Description

A method and device for transmitting an uplink response message

technical field

The present invention relates to the technical field of communication, in particular to a technology for transmitting an uplink response message.

Background technique

A machine type communication (MTC, Machine Type Communication) device is a user equipment (UE, User Equipment) used by a machine for a specific application. An example of the MTC device is a smart meter. Some of these smart meters are located in basements, which suffer from high penetration loss, so communication with the network is difficult for MTC devices. Therefore, in 3GPP, a new project group on low-cost MTC UE and coverage enhancement was approved. The goal of coverage enhancement is to extend the coverage of such MTC UEs by 15dB. We call such UEs Coverage Enhanced Machine Type Communication User Equipment (CE-MTC UE, Coverage Enhanced MTCUE).

In order to achieve 15dB coverage enhancement, it is expected to repeat dozens to hundreds of times PRACH (Physical Random Access Channel, Physical Random Access Channel) and PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel), which reduces the spectral efficiency of the system to 1/100 of the system, therefore, techniques to improve the spectral efficiency of the system are required. An important aspect of the spectrum efficiency problem is the signaling overhead, because the transmission is still dynamically scheduled on the PDCCH (Physical Downlink Control Channel). 100 repetitions means that PDSCH (Physical Downlink Shared Channel)/PUSCH and PDCCH need so many repetitions. Moreover, the typical application is that the meter-type equipment is characterized by small data transmission, so the signaling overhead is more important than other services such as web browsing. A useful method to reduce signaling overhead is continuous scheduling, especially when CSI (Channel State Information, Channel State Information) is unknown. However, this method has little effect, because the main transmission of the session is about signaling. Figure 1 shows the corresponding signaling flow in the process of UE random access to eNB (evolved Node B). A typical application of an electricity meter sends only a small number of packets, which makes continuous scheduling of the application difficult. Another possible way to reduce signaling is persistent scheduling of signaling transmissions, but this also does not work well because signaling flows are more complex and sometimes unpredictable than data transmissions, and this can sometimes be modeled by a state machine. Therefore, traditional persistent scheduling methods waste resources when there is data transmission. Second, as each signaling needs to be repeated 100 times, the current signaling flow has excessive delay, which means that the UE needs more power to decode and/or transmit more messages, thus consuming more power.

Specifically, the detection device 11 of the base station 1 detects whether the mobile device 2 served by the base station 1 satisfies the scheduling trigger condition for pair scheduling; when the scheduling trigger condition is met and the base station 1 sends a downlink message, the sending unit 12 determines the uplink resource allocation information of the uplink response message corresponding to the downlink message of the mobile device 2, so as to use the identification information for pairing scheduling of the mobile device 2 and the uplink resource allocation information The allocation information is sent to the mobile device 2; correspondingly, the receiving device 21 of the mobile device 2 receives the identification information for pairing scheduling of the mobile device 2 sent by the base station 1 serving the mobile device 2, and the base station 1 The uplink resource allocation information of the uplink response message corresponding to the downlink message of the mobile device 2 determined when the downlink message is sent to the mobile device 2; the response sending unit 22 is based on the uplink resource allocation information according to the identification information resource allocation information, and transmit the uplink response message to the base station 1 .

Here, the mobile device refers to the part of the mobile communication device that terminates the wireless transmission from or to the network and adapts the capabilities of the terminal device to the wireless transmission, that is, the device that the user accesses the mobile network, including But not limited to any electronic product that can interact with the user through keyboards, touch panels, or voice-controlled devices, and can transmit and receive signals with the base station through the mobile network to achieve the transmission of mobile communication signals, such as tablet computers , smartphones, PDAs, vehicle computers, UEs for coverage enhancement, MTC devices, CE-MTC UEs, CE-MTC devices, etc. Here, the base station refers to a device in the mobile communication system that connects the fixed part and the wireless part and connects with the mobile station through wireless transmission in the air, including but not limited to eNB base stations and the like. Here, the mobile network includes but not limited to GSM, 3G, LTE, Wi-Fi, WiMax, WCDMA, CDMA2000, TD-SCDMA, HSPA, LTD and so on. Those skilled in the art should be able to understand that the above-mentioned mobile equipment, base station and mobile network are only examples, and other existing or future user equipment or base stations or mobile networks, if applicable to the present invention, should also be included in the protection scope of the present invention , and is hereby incorporated by reference.

Specifically, the detection means 11 of the base station 1 detects whether the mobile equipment served by the base station meets the scheduling trigger condition for pair scheduling.

Here, the meaning of the paired scheduling (a paired scheduling) refers to scheduling possible RRC uplink feedback messages at the same time in the signaling of scheduling downlink RRC (Radio Resource Control, Radio Resource Control) messages, for example, based on the message being mechanism for the organization (for example, in the signaling flow shown in Figure 1, the uplink message "RRC connection reconfiguration" is followed by the corresponding downlink response message "RRC connection reconfiguration complete" ("RRC connection reconfiguration" and "RRC connection reconfiguration complete" constitutes a pairing message)), when the base station eNB sends a downlink message to the mobile device UE, it can know the uplink response message that the mobile device UE will send in response to the downlink message, and estimate the uplink response The size of the message, so that information such as the uplink resource allocation of the corresponding uplink response message can be sent at the same time when the downlink message is sent, so that uplink resources and downlink resources can be allocated in the same resource allocation message. Figure 3 shows the signaling that satisfies the pairing scheduling shown in Figure 1, wherein the signaling in the thick dotted line "---" box is the pairing signaling, as can be seen from Figure 3, the pairing scheduling of the present invention can be used in Most of the signaling is used in transmission, 12 of the 18 signalings shown in Figure 3 can use pair scheduling, therefore, about 30% of the signaling can be saved, and correspondingly, the power of the mobile device is also saved.

Here, the scheduling trigger conditions include but are not limited to at least any of the following: 1) The preamble sequence used by the mobile device to randomly access the base station meets a predetermined sequence number, for example, the mobile device randomly accesses the base station At this time, the preamble sequence sent on PRACH (Physical Random Access Channel) is 31-56, while the preamble sequence used by normal UE to access the base station is 1-30; Ⅱ) The mobile device The subframe in which the PRACH is sent when accessing the base station meets the predetermined subframe number, that is, the PRACH when the mobile device accesses the base station and the PRACH when a normal UE accesses the base station are sent in different subframes. The UE transmits in subframe 0, and the mobile device can transmit in the remaining subframes. Those skilled in the art should be able to understand that the above scheduling trigger conditions are only examples, and other existing or future scheduling trigger conditions, if applicable to the present invention, should also be included within the protection scope of the present invention, and are hereby referenced included here.

For example, assume that when mobile device 2 starts up and initially accesses the network, it searches for a cell covered by base station 1 and realizes synchronization with the cell. Then, mobile device 2 applies for the possibility of establishing a network connection with base station 1, that is, realizes Random access of base station 1 to establish uplink synchronization. Assuming that the preamble sequence sent on the PRACH when mobile device 2 randomly accesses base station 1 is preamble50, and the above scheduling trigger condition I is satisfied, detection device 11 can determine that the mobile device 2 Satisfy the scheduling trigger condition for pair scheduling. For another example, assuming that mobile device 2 sends PRACH on subframe 0 when randomly accessing base station 1, and does not satisfy the above scheduling trigger condition II, detection device 11 may determine that mobile device 2 does not meet the scheduling trigger condition for pair scheduling.

Those skilled in the art should be able to understand that the above method of detecting whether the mobile device satisfies the scheduling trigger condition for pairing scheduling is only an example, and other existing or future methods for detecting whether the mobile device meets the scheduling trigger condition for pairing scheduling Conditional means, if applicable to the present invention, shall also be included within the protection scope of the present invention, and are incorporated herein by reference.

When the scheduling trigger condition is satisfied and the base station sends a downlink message to the mobile device, the sending unit 12 determines the uplink resource allocation information of the uplink response message corresponding to the downlink message about the mobile device, so as to The identification information for performing pair scheduling on the mobile device and the uplink resource allocation information are sent to the mobile device.

Here, the identification information is used to indicate whether the paired scheduling is used, which can be defined in the DCI (downlink control information, Downlink Control Information) of the downlink scheduling, or can be defined in a system message such as SIB (system Message block, SystemInformation Block) to define.

Here, the uplink resource allocation information includes but not limited to at least any of the following: i) Uplink resource block allocation information corresponding to the uplink response message; ii) Resource block starting position corresponding to the uplink response message information and resource block quantity information; iii) the offset information (offset) between the first physical resource block corresponding to the uplink response message and the first physical resource block corresponding to the downlink message; iv) the uplink Time interval information (timing) between the response message and the downlink message. Here, the uplink resource allocation information can be defined in DCI of downlink scheduling, or can be defined in system information such as SIB. Preferably, the offset information can be indicated in the SIB, and the time interval information can also be indicated in the SIB.

Here, only the identification information and the uplink resource allocation information shown in the DCI are taken as an example for illustration, and the existing DCI format 1A, DCI format 1, and DCI format 1C are respectively improved, as described in the newly added A bit of the identification information and a bit of the uplink resource allocation information to show the identification information and the uplink resource allocation information:

1) DCI format 1A is improved to obtain DCI format 1A', the information included and the bits occupied by each information are as follows:

- Uplink resource block allocation – 3bits

2) DCI format 1 is improved to obtain DCI format 1', the information it includes and the bits occupied by each information are as follows:

- Carrier indication – 0 or 3 bits

- Resource block allocation

-Modulation and coding scheme – 2bits

-Number of HARQ processes – 3bits (FDD, Frequency Division Duplexing), 4bits (TDD, Time Division Duplexing)

- New data indication – 1bit

-Redundant version – 2bits

-PUCCH power control command – 2bits

- Downlink allocation index (for FDD) – 2bits

- Pair scheduling uses –1bit

- Uplink resource block allocation – 3bits

3) DCI format 1C is improved to obtain DCI format 1C', the information included and the bits occupied by each information are as follows:

-1bit indicates the gap value

- Resource block allocation

-Modulation and coding scheme – 2bits

- Pair scheduling uses –1bit

- Uplink resource block allocation – 3bits

Here, the "pairing scheduling usage" bit in the above-mentioned DCI format 1A', DCI format 1', and DCI format 1C' is used to indicate whether the pairing scheduling is used, that is, to reflect the identification information. The above-mentioned DCI format 1A The "uplink resource block allocation" bit in ', DCI format 1', and DCI format 1C' shows the uplink resource allocation information. In addition, for those skilled in the art, by comparing the above DCI format 1A', DCI format 1', and DCI format 1C' with DCI format 1A, DCI format 1, and DCI format 1C in the prior art, it can be found that, Some information in DCI format 1A, DCI format 1, and DCI format 1C in the prior art is unnecessary in the above-mentioned DCI format 1A', DCI format 1', and DCI format 1C', and the number of bits of some information can be Reduced, here, only DCI format 1A is used as an example for illustration, such as "SRS (Sounding Reference Signal, Sounding Reference Signal) request-0 or 1 bit" in DCI format 1A in the prior art is not valid for DCI format 1A' Necessary, the "modulation and coding scheme" is 5 bits in DCI format 1A, and 3 bits in DCI format 1A'. Therefore, the total number of bits in DCI format 1A' and DCI format 1A has not changed; for another example, for The maximum resource to be allocated to the mobile device 2 is 6 PRBs (Physical Resource Block, Physical Resource Block), so the number of bits used for resource allocation is small, which is sufficient for uplink resource allocation in the same message.

Specifically, when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device, the sending unit 12 may first determine the uplink resource of the uplink response message corresponding to the downlink message about the mobile device Allocation information, such as determining the uplink resource allocation information according to the historical uplink resource allocation information of the mobile device, so as to send the uplink resource allocation information to the mobile device; and then pairing the mobile device The scheduled identification information and the uplink resource allocation information are sent to the mobile device.

For example, as for the mobile equipment 2, assuming that the detection device 11 determines that the mobile equipment 2 satisfies the scheduling trigger condition, when the base station 1 receives a new downlink message from a higher layer such as RRC, the base station 1 sends the mobile equipment 2 a message as shown in Figure 1 The downlink message shown is "When the RRC connection is established", because the uplink response message "RRC establishment complete" and "RRC connection establishment" as shown in Figure 1 are paired messages, the base station 1 can predict that the mobile device 2 will respond to the downlink message "RRC connection establishment" is the uplink resource allocation information when sending "RRC establishment complete" to base station 1. Assume that when mobile device 2 sends "RRC establishment complete" to base station 1 in history, base station 1 assigns this uplink response to mobile device 2 The historical uplink resource allocation information of the message is 3PRBs, then when the base station 1 performs pairing scheduling on the mobile device 2 and the base station 1 sends the downlink message "RRC connection establishment" to the mobile device 2, the sending device 12 can determine the relationship between the mobile device 2 and the The uplink resource assignment information of the uplink response message corresponding to the above downlink message is UL resource assignment=3PRBs.

Next, the sending unit 12 sends to the mobile device 2 identification information for performing pair scheduling on the mobile device 2 and the uplink resource allocation information. For example, following the above example, assuming that the base station 1 chooses to use the above-mentioned DCI format 1A' to send the identification information and the uplink resource allocation information to the mobile device 2, the sending device 12 can first generate corresponding scheduling information such as scheduling-DCI1A' , wherein the scheduling information scheduling-DCI1A' includes the identification information and the uplink resource allocation information, for example, the bit value corresponding to "pair scheduling usage" in scheduling-DCI1A' is "1" (here, bit The value of the bit shows the identification information, for example, "1" or "0" can be predetermined to indicate whether the paired scheduling is used), and the bit value in "uplink resource block allocation" in scheduling-DCI1A' is "011" (Here, the value of the bit shows the number of PRBs in the uplink resource allocation information, because the "uplink resource block allocation" in the above-mentioned DCI1A' occupies 3 bits, and the uplink resource allocation information first determined by the sending device 12 is 3PRBs , therefore, the bit value here is "011"); then, the sending device 12 sends the scheduling information scheduling-DCI1A' to the mobile device 2 through a mobile network such as LTE (Long Term Evolution), so as to send the identification The information and the uplink resource allocation information are sent to the mobile device 2. Here, the manner of showing the identification information and the uplink resource allocation information in the DCI information is only an example, and other existing or future possible ways of showing the identification information and the uplink resource allocation information in the DCI information The way of distributing information, if applicable to the present invention, should also be included in the protection scope of the present invention, and is hereby incorporated by reference.

Here, the present invention enables the base station to allocate the uplink and downlink resources in the same resource allocation message by sending the identification information of the pairing scheduling and the uplink resource allocation information of the uplink response message corresponding to the downlink message to the mobile equipment performing the pairing scheduling. resources to achieve the beneficial effect of reducing signaling overhead, which can save 50% of signaling overhead.

Preferably, when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device, the sending unit 12 may first determine the uplink resource of the uplink response message corresponding to the downlink message about the mobile device allocation information, so as to send the uplink resource allocation information to the mobile device; or, when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device, the sending device 12 may first generate the corresponding first Two scheduling information, wherein the second scheduling information includes identification information for performing pairing scheduling on the mobile device; and then, sending the second scheduling information to the mobile device, so as to send the identification information to the mobile device.

Specifically, when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device, the sending unit 12 may first determine the uplink resource of the uplink response message corresponding to the downlink message about the mobile device Assignment information. Here, the method of determining the uplink resource allocation information by the sending device 12 is the same or basically the same as the above-mentioned method of determining the uplink resource allocation information by the sending device 12. included with this.

Then, the sending unit 12 sends the uplink resource allocation information to the mobile device, such as generating corresponding system information according to the uplink resource allocation information, wherein the system information includes the uplink resource allocation information; then, the The system information is broadcast to the mobile device, so as to send the uplink resource allocation information to the mobile device. For example, for the mobile equipment 2, assuming that the detecting means 11 determines that the mobile equipment 2 satisfies the scheduling trigger condition, when the base station 1 receives a new downlink message from a higher layer such as RRC, the sending means 12 first determines the information about the mobile equipment 2 and the The uplink resource assignment information of the uplink response message corresponding to the downlink message is UL resource assignment=3PRBs, then the sending device 12 can generate a corresponding system message such as SIB according to the uplink resource assignment information, and the system information SIB includes the uplink resource Assignment information UL resourceassignment=3PRBs; then, the sending device 12 periodically broadcasts the system message SIB to the mobile device 2 through a mobile network such as LTE.

Alternatively, when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device, the sending device 12 may first generate corresponding second scheduling information, wherein the second scheduling information includes Perform identification information for pairing scheduling; then, send the second scheduling information to the mobile device, so as to send the identification information to the mobile device. For example, following the above example, the detection device 11 determines that the mobile device 2 satisfies the scheduling trigger condition, assuming that the base station 1 chooses to use the DCI format 1' to send the identification information and the uplink resource allocation information to the mobile device 2, then The sending device 12 may first generate the corresponding second scheduling information such as scheduling-DCI1', wherein the second scheduling information scheduling-DCI1' includes the identification information, such as the bit corresponding to "pair scheduling use" in scheduling-DCI1' The bit value is "1"; then, the sending means 12 sends the second scheduling information scheduling-DCI1' to the mobile device 2 through a mobile network such as LTE, so as to send the identification information to the mobile device 2.

Here, the present invention sends the identification information only in the scheduling information (that is, only in the DCI information), and sends the uplink resource allocation information in the system message (such as in the SIB), so that the DCI information is used for uplink resource allocation The bits of the DCI information can be reduced to the minimum, that is, the number of bits of the DCI information is reduced, and the beneficial effect of further reducing signaling overhead is achieved.

Here, those skilled in the art should understand that the present invention may also only send the uplink resource allocation information in scheduling information (that is, only DCI information), and send the identification information in system information (such as SIB).

Preferably, the pair scheduling in the present invention can be used together with dynamic scheduling and continuous scheduling of data. Mobile device 2 can use a scheduling request (SR, Scheduling Request) to request additional resources for uplink transmission, and base station 1 can also schedule mobile device 2 in one direction, uplink or downlink, when scheduling in that direction is needed.

Preferably, the pairing scheduling of the mobile device in the present invention can be predetermined, or configured by a high-level message; the signaling message pair used in the pairing scheduling can be defined in the standard, or be related to the resource quantity allocated for the corresponding uplink response message Together they are indicated in system messages such as SIBs.

Correspondingly, the receiving unit 21 of the mobile device 2 receives the identification information for pairing scheduling of the mobile device 2 sent by the base station 1 serving the mobile device 2 through a mobile network such as LTE, and the base station 1 sends the mobile device 2 to the mobile device 2. The uplink resource allocation information of the uplink response message corresponding to the downlink message about the mobile device 2 determined when the device 2 sends the downlink message.

The response sending unit 22 transmits the uplink response message to the base station 1 according to the identification information and based on the uplink resource allocation information. For example, for the mobile device 2, it is assumed that the receiving device 21 receives the identification information for pairing scheduling of the mobile device 2 sent by the base station 1 serving the mobile device 2, such as the scheduling information scheduling- In DCI1A', the value of the bit corresponding to the "used for pairing scheduling" of the identification information is "1", and the connection with the mobile device 2 determined when the base station 1 sends a downlink message to the mobile device 2 The uplink resource allocation information of the uplink response message corresponding to the downlink message is determined when the base station 1 sends the downlink message "RRC connection establishment" to the mobile device 2 indicated in the scheduling information scheduling-DCI1A' sent by the sending device 12 of the base station 1 The uplink resource allocation information of the uplink response message "RRC establishment complete" corresponding to the downlink message "RRC connection establishment" of the mobile device 2, such as the bit value in "uplink resource block allocation" in scheduling-DCI1A' is "011", then the response sending device 22 sends an uplink response message "RRC establishment complete" on the 3 PRBs continuously allocated in the frequency domain according to the identification information, or, after a predetermined delay time, on the 3 PRBs continuously allocated in the frequency domain An uplink response message "RRC establishment complete" is sent on the 3 PRBs.

As another example, assume that the receiving unit 21 of the mobile device 2 receives the identification information for pairing scheduling of the mobile device 2 sent by the base station 1 serving the mobile device 2, such as the scheduling information scheduling- In DCI1A', the value of the bit corresponding to the "use of pairing scheduling" of the identification information is "1", and the connection between the mobile device 2 and the mobile device 2 determined when the base station 1 sends the downlink message "RRC connection establishment" to the mobile device 2 The uplink resource allocation information of the uplink response message "RRC establishment complete" corresponding to the downlink message "RRC connection establishment", the uplink resource allocation information is shown in Figure 4, wherein the uplink resource allocation information includes: 1) Uplink response message The offset information offset between the first physical resource block corresponding to "RRC establishment complete" and the first physical resource block corresponding to the downlink message "RRC connection establishment"; 2) the uplink response message "RRC establishment complete" and the downlink message The time interval information timing between "RRC connection establishment"; 3) The resource block number information corresponding to the uplink response message "RRC establishment complete", such as 3PRBs, the response sending device 22 can determine to send the uplink response according to the offset information offset The starting position of the PRB for the message "RRC establishment complete", after the time interval timing, the uplink response message "RRC establishment complete" is sent on the 3 PRBs continuously allocated in the frequency domain starting from the starting position.

Various devices of the base station 1 and the mobile device 2 are continuously working. Specifically, the detection device 11 of the base station 1 continuously detects whether the mobile device 2 served by the base station 1 meets the scheduling trigger condition for pair scheduling; when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device When , the sending unit 12 continues to determine the uplink resource allocation information of the uplink response message corresponding to the downlink message of the mobile device 2, so as to assign the identification information of the mobile device 2 to pair scheduling and the uplink resource The allocation information is sent to the mobile device 2; correspondingly, the receiving device 21 of the mobile device 2 continues to receive the identification information for pairing scheduling of the mobile device 2 sent by the base station 1 serving the mobile device 2, and the base station 1 The uplink resource allocation information of the uplink response message corresponding to the downlink message of the mobile device 2 determined when sending the downlink message to the mobile device 2; The uplink resource allocation information is transmitted to the base station 1 with the uplink response message. Those skilled in the art should understand that "persistent" means that each device of the base station 1 and the mobile device 2 respectively continuously detects whether the trigger condition for pairing scheduling is met, sends and receives identification information for pairing scheduling, and uplink resource allocation information 1. Sending the uplink response message until the mobile device 2 served by the base station 1 stops the detector for a long time to meet the scheduling trigger condition for pair scheduling.

Fig. 5 shows a base station 1 for transmitting an uplink response message according to a preferred embodiment of the present invention, wherein the base station 1 includes a detection device 11' and a sending device 12', wherein the sending device 12' includes a determining unit 121' and a sending device Unit 122'. Specifically, the detection device 11' of the base station 1 detects whether the mobile device 2 served by the base station 1 satisfies the scheduling trigger condition for pair scheduling; when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device , the determining unit 121' determines the uplink resource allocation information of the uplink response message corresponding to the downlink message about the mobile device; the sending unit 122' performs pairing scheduling identification information on the mobile device and the uplink Resource allocation information is sent to the mobile device. Here, the content of the detection device 11' is the same or substantially the same as that of the corresponding device in the specific embodiment in FIG.

Specifically, when the scheduling trigger condition is satisfied and the base station sends a downlink message to the mobile device, the determining unit 121' determines the uplink resource allocation of the uplink response message corresponding to the downlink message of the mobile device information. Here, the manner of determining the uplink resource allocation information by the determining unit 121' includes but not limited to at least any of the following:

1) According to the device type information of the mobile device, determine the uplink resource allocation information of the uplink response message corresponding to the downlink message about the mobile device. Here, the device type information includes, but is not limited to, low-cost type devices, high-cost type devices, and the like. For example, for the mobile equipment 2, assuming that the detecting device 11' determines that the mobile equipment 2 satisfies the scheduling trigger condition, when the base station 1 receives a new downlink message from a higher layer such as RRC, for example, the base station 1 sends a message to the mobile equipment 2 as shown in Figure 1 The downlink message shown is "When the RRC connection is established", because the uplink response message "RRC establishment complete" and "RRC connection establishment" as shown in Figure 1 are paired messages, the base station 1 can predict that the mobile device 2 will respond to the downlink message "RRC connection establishment" is to send the uplink resource allocation information when "RRC establishment is completed" to base station 1, for example, according to the capability of mobile device 2 and the stored information, estimate the uplink response message "RRC establishment is completed" to be sent Which parameters are available and which parameters are not used, so as to estimate the number of bits in the uplink response message "RRC establishment complete", and then calculate the required uplink resource allocation information, that is, the required number of PRBs, such as assuming that the mobile device is low For cost-type devices, for the uplink response message "RRC establishment complete", registeredMME is an option. If the system has only one MME (Mobility Management Entity) or all mobile devices accessing base station 1 use a certain MME, Then for the uplink response message "RRC establishment complete", the registeredMME parameter may not be sent, then the determining unit 121' may first determine that the number of bits of the uplink response message "RRC establishment complete" is the number of bits after subtracting the bits occupied by the registeredMME parameter, that is 17+ fixed MAC and RLC headers are required; then, determine the MCS (Modulation and Coding Scheme) according to the bit error rate performance, and then determine the required number of PRBs according to the number of bits that can be transmitted by each PRB, such as 2PRBs, that is, the determining unit 121' determines that the uplink resource allocation information is 2PRBs.

2) According to the historical uplink resource allocation information of the mobile equipment, determine the uplink resource allocation information of the uplink response message corresponding to the downlink message about the mobile equipment. For example, assuming that the detection device 11' determines that the mobile device 2 satisfies the scheduling trigger condition, when the base station 1 receives a new downlink message from a higher layer such as RRC, the base station 1 sends the downlink message as shown in Figure 1 to the mobile device 2 For example, "when the RRC connection is established", because the uplink response message "RRC establishment complete" and "RRC connection establishment" as shown in Figure 1 are paired messages, the base station 1 can predict that the mobile device 2 will respond to the downlink message "RRC connection establishment" That is, the uplink resource allocation information when sending "RRC establishment complete" to base station 1, assuming that when mobile device 2 sends "RRC establishment complete" to base station 1 in history, base station 1 allocates the historical uplink resource of the uplink response message for mobile device 2 The allocation information is 3PRBs, then when the base station 1 performs pairing scheduling on the mobile device 2 and the base station 1 sends the downlink message "RRC connection establishment" to the mobile device 2, the determination unit 121' can determine that the mobile device 2 is related to the downlink message The uplink resource allocation information of the corresponding uplink response message is ULresource assignment=3PRBs.

Those skilled in the art should understand that the above method of determining the uplink resource allocation information is only an example, and other existing or future possible methods of determining the uplink resource allocation information, if applicable to the present invention, should also be included in the within the scope of this invention and is hereby incorporated by reference.

The sending unit 122' sends the identification information for performing pair scheduling on the mobile device and the uplink resource allocation information to the mobile device. Here, the manner in which the sending unit 122' sends the identification information and the uplink resource allocation information includes but is not limited to at least any of the following:

1) First generate corresponding system information, where the system information includes identification information for performing pair scheduling on the mobile device and the uplink resource allocation information; then, broadcast the system information to the mobile device to sending the identification information and the uplink resource allocation information to the mobile equipment. For example, following the above example, the determining unit 121' determines that the uplink resource assignment information of the uplink response message corresponding to the downlink message of the mobile device 2 is UL resource assignment=3PRBs, then the sending unit 122' may first generate the corresponding System information such as SIB', the system information SIB' includes identification information for pairing scheduling of the mobile device 2, such as improving the system information SIB in the prior art to obtain the system information SIB' suitable for the present invention, such as first in the SIB Add information "Pairing Scheduling Use – 1bit" to obtain SIB', where the "Pairing Scheduling Use" bit is used to indicate whether the pairing scheduling is used, that is, to reflect the identification information, such as "1" or "0" indicates whether the paired scheduling is used, and at the same time, add the uplink resource assignment information UL resource assignment=3PRBs in the SIB; then, the sending unit 122' transmits to the mobile network such as LTE (Long Term Evolution) Device 2 periodically broadcasts the system message SIB'.

2) First generate corresponding first scheduling information, where the first scheduling information includes identification information for performing pair scheduling on the mobile device, and the uplink resource allocation information; then, send the first scheduling information to the mobile device, so as to send the identification information and the uplink resource allocation information to the mobile device. For example, following the above example, assuming that the base station 1 chooses to use the above-mentioned DCI format 1C' to send the identification information and the uplink resource allocation information to the mobile device 2, the sending unit 122' can first generate corresponding first scheduling information such as scheduling -DCI1C', wherein the first scheduling information scheduling-DCI1C' includes the identification information and the uplink resource allocation information, such as the bit number value corresponding to "pair scheduling use" in scheduling-DCI1C' is "1" (Here, the value of the bit shows the identification information, such as "1" or "0" can be predetermined to indicate whether the paired scheduling is used), the bit in "uplink resource block allocation" in scheduling-DCI1C' The value is "011" (here, the value of the bit shows the number of PRBs in the uplink resource allocation information, because the "uplink resource block allocation" in the above-mentioned DCI1C' occupies 3 bits, and the determining unit 121' first determines The uplink resource allocation information is 3PRBs, therefore, the bit value here is "011"); then, the sending unit 122' sends the first scheduling information scheduling-DCI1C' to the mobile device 2 through a mobile network such as LTE, to Send the identification information and the uplink resource allocation information to the mobile device 2 .

Those skilled in the art should be able to understand that the above-mentioned way of sending the identification information and the uplink resource allocation information is only an example, and other existing or future ways of sending the identification information and the uplink resource allocation information are as follows: It is applicable to the present invention, and should also be included in the protection scope of the present invention, and is hereby incorporated by reference.

Fig. 6 shows a flowchart of a method for cooperating between a mobile device and a base station to transmit an uplink response message according to another aspect of the present invention.

Specifically, in step S1, the base station 1 detects whether the mobile device 2 served by the base station 1 satisfies the scheduling trigger condition for pair scheduling; when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device , in step S2, the base station 1 determines the uplink resource allocation information of the uplink response message corresponding to the downlink message of the mobile device 2, so as to use the identification information for performing pairing scheduling on the mobile device 2 and the The above uplink resource allocation information is sent to the mobile device 2; correspondingly, the mobile device 2 receives the identification information for performing pairing scheduling on the mobile device 2 sent by the base station 1 serving the mobile device 2, and the base station 1 sends The uplink resource allocation information of the uplink response message corresponding to the downlink message of the mobile device 2 determined when the mobile device 2 sends the downlink message; in step S3, the mobile device 2 is based on the identification information, The uplink resource allocation information transmits the uplink response message to the base station 1 .

Here, the mobile device refers to the part of the mobile communication device that terminates the wireless transmission from or to the network and adapts the capabilities of the terminal device to the wireless transmission, that is, the device that the user accesses the mobile network, including But not limited to any electronic product that can interact with the user through keyboards, touch panels, or voice-controlled devices, and can transmit and receive signals with the base station through the mobile network to achieve the transmission of mobile communication signals, such as tablet computers , smartphones, PDAs, vehicle computers, UEs for coverage enhancement, MTC devices, CE-MTC UEs, CE-MTC devices, etc. Here, the base station refers to a device in the mobile communication system that connects the fixed part and the wireless part and connects with the mobile station through wireless transmission in the air, including but not limited to eNB base stations and the like. Here, the mobile network includes but not limited to GSM, 3G, LTE, Wi-Fi, WiMax, WCDMA, CDMA2000, TD-SCDMA, HSPA, LTD and so on. Those skilled in the art should be able to understand that the above-mentioned mobile equipment, base station and mobile network are only examples, and other existing or future user equipment or base stations or mobile networks, if applicable to the present invention, should also be included in the protection scope of the present invention , and is hereby incorporated by reference.

Specifically, in step S1 of the base station 1, the base station 1 detects whether the mobile device served by the base station satisfies the scheduling trigger condition for pair scheduling.

Here, the meaning of the paired scheduling (a paired scheduling) refers to scheduling possible RRC uplink feedback messages at the same time in the signaling of scheduling downlink RRC (Radio Resource Control, Radio Resource Control) messages, for example, based on the message being mechanism for the organization (for example, in the signaling flow shown in Figure 1, the uplink message "RRC connection reconfiguration" is followed by the corresponding downlink response message "RRC connection reconfiguration complete" ("RRC connection reconfiguration" and "RRC connection reconfiguration complete" constitutes a pairing message)), when the base station eNB sends a downlink message to the mobile device UE, it can know the uplink response message that the mobile device UE will send in response to the downlink message, and estimate the uplink response The size of the message can send information such as the uplink resource allocation of the corresponding uplink response message at the same time when sending the downlink message, so as to realize the method of allocating uplink resources and downlink resources in the same resource allocation message. Figure 3 shows the signaling that satisfies the pairing scheduling shown in Figure 1, wherein the signaling in the thick dotted line "---" box is the pairing signaling, as can be seen from Figure 3, the pairing scheduling of the present invention can be used in Most of the signaling is used in transmission, 12 of the 18 signalings shown in Figure 3 can use pair scheduling, therefore, about 30% of the signaling can be saved, and correspondingly, the power of the mobile device is also saved.

Here, the scheduling trigger conditions include but are not limited to at least any of the following: 1) The preamble sequence used by the mobile device to randomly access the base station meets a predetermined sequence number, for example, the mobile device randomly accesses the base station At this time, the preamble sequence sent on PRACH (Physical Random Access Channel) is 31-56, while the preamble sequence used by normal UE to access the base station is 1-30; Ⅱ) The mobile device The subframe in which the PRACH is sent when accessing the base station meets the predetermined subframe number, that is, the PRACH when the mobile device accesses the base station and the PRACH when a normal UE accesses the base station are sent in different subframes. The UE transmits in subframe 0, and the mobile device can transmit in the remaining subframes. Those skilled in the art should be able to understand that the above scheduling trigger conditions are only examples, and other existing or future scheduling trigger conditions, if applicable to the present invention, should also be included within the protection scope of the present invention, and are hereby referenced included here.

For example, assume that when mobile device 2 starts up and initially accesses the network, it searches for a cell covered by base station 1 and realizes synchronization with the cell. Then, mobile device 2 applies for the possibility of establishing a network connection with base station 1, that is, realizes Random access of base station 1 to establish uplink synchronization. Assume that the preamble sequence sent on the PRACH when mobile device 2 randomly accesses base station 1 is preamble50, which satisfies the above scheduling trigger condition I, then in step S1, base station 1 It can be determined that the mobile device 2 satisfies the scheduling trigger condition for pair scheduling. For another example, assuming that mobile device 2 sends PRACH on subframe 0 when it randomly accesses base station 1, and does not meet the above scheduling trigger condition II, then in step S1, base station 1 may determine that mobile device 2 does not meet the scheduling trigger for pair scheduling condition.

Those skilled in the art should understand that the above method of detecting whether the mobile device satisfies the scheduling trigger condition for pairing scheduling is only an example, and other existing or future methods for detecting whether the mobile device meets the scheduling trigger condition for pairing scheduling Conditional means, if applicable to the present invention, shall also be included within the protection scope of the present invention, and are incorporated herein by reference.

When the scheduling trigger condition is satisfied and the base station sends a downlink message to the mobile device, in step S2, the base station 1 determines the uplink resource of the uplink response message corresponding to the downlink message about the mobile device 2 Allocating information, so as to send to the mobile device 2 identification information for performing pair scheduling on the mobile device 2 and the uplink resource allocation information.

Here, the identification information is used to indicate whether the paired scheduling is used, which can be defined in the DCI (downlink control information, Downlink Control Information) of the downlink scheduling, or can be defined in a system message such as SIB (system Message block, SystemInformation Block) to define.

Here, the uplink resource allocation information includes but not limited to at least any of the following: i) Uplink resource block allocation information corresponding to the uplink response message; ii) Resource block starting position corresponding to the uplink response message information and resource block quantity information; iii) the offset information (offset) between the first physical resource block corresponding to the uplink response message and the first physical resource block corresponding to the downlink message; iv) the uplink Time interval information (timing) between the response message and the downlink message. Here, the uplink resource allocation information can be defined in DCI resource allocation for downlink scheduling, or can be defined in system information such as SIB. Preferably, the offset information can be indicated in the SIB, and the time interval information can also be indicated in the SIB.

Here, only the identification information and the uplink resource allocation information shown in the DCI are taken as an example for illustration, and the existing DCI format 1A, DCI format 1, and DCI format 1C are respectively improved, as described in the newly added A bit of the identification information and a bit of the uplink resource allocation information to show the identification information and the uplink resource allocation information:

1) DCI format 1A is improved to obtain DCI format 1A', the information included and the bits occupied by each information are as follows:

-1bit indicates the gap value

- Resource block allocation

- Pair scheduling uses –1bit

- Uplink resource block allocation – 3bits

Here, the "pairing scheduling usage" bit in the above-mentioned DCI format 1A', DCI format 1', and DCI format 1C' is used to indicate whether the pairing scheduling is used, that is, to reflect the identification information. The above-mentioned DCI format 1A The "uplink resource block allocation" bit in ', DCI format 1', and DCI format 1C' shows the uplink resource allocation information. In addition, for those skilled in the art, by comparing the above DCI format 1A', DCI format 1', and DCI format 1C' with DCI format 1A, DCI format 1, and DCI format 1C in the prior art, it can be found that, Some information in DCI format 1A, DCI format 1, and DCI format 1C in the prior art is unnecessary in the above-mentioned DCI format 1A', DCI format 1', and DCI format 1C', and the number of bits of some information can be Reduced, here, only DCI format 1A is used as an example for illustration, such as "SRS (Sounding Reference Signal) request-0 or 1 bit" in DCI format 1A in the prior art is unnecessary for DCI format 1A' Yes, the "modulation and coding scheme" is 5 bits in DCI format 1A, and 3 bits in DCI format 1A'. Therefore, the total number of bits in DCI format 1A' and DCI format 1A has not changed; The maximum resource allocated to mobile device 2 is 6 PRBs (Physical Resource Block, Physical Resource Block), so the number of bits used for resource allocation is small, which is sufficient for uplink resource allocation in the same message.

Specifically, when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device, in step S2, the base station 1 may first determine the uplink response corresponding to the downlink message about the mobile device The uplink resource allocation information of the message, such as determining the uplink resource allocation information according to the historical uplink resource allocation information of the mobile device, so as to send the uplink resource allocation information to the mobile device; The identification information of the mobile device performing pair scheduling and the uplink resource allocation information are sent to the mobile device.

For example, as for the mobile device 2, assuming that in step S1, the base station 1 determines that the mobile device 2 satisfies the scheduling trigger condition, then when the base station 1 receives a new downlink message from a higher layer such as RRC, if the base station 1 sends a message to the mobile device 2 Send the downlink message as shown in Figure 1, such as "RRC connection establishment", because the uplink response message "RRC establishment complete" and "RRC connection establishment" as shown in Figure 1 are paired messages, then base station 1 can predict that the mobile device 2 Responding to the downlink message "RRC connection established", that is, sending the uplink resource allocation information to base station 1 when "RRC establishment is completed", assuming that mobile device 2 has historically sent "RRC establishment complete" to base station 1, base station 1 allocates resources for mobile device 2 The historical uplink resource allocation information of the uplink response message is 3PRBs, then when the base station 1 performs pairing scheduling on the mobile device 2 and the base station 1 sends the downlink message "RRC connection establishment" to the mobile device 2, in step S2, the base station 1 can Determine that the uplink resource assignment information of the uplink response message corresponding to the downlink message on the mobile device 2 is UL resource assignment=3PRBs.

Next, in step S2 , the base station 1 sends to the mobile device 2 identification information for performing pair scheduling on the mobile device 2 and the uplink resource allocation information. For example, following the above example, assuming that the base station 1 chooses to use the above-mentioned DCI format 1A' to send the identification information and the uplink resource allocation information to the mobile device 2, then in step S2, the base station 1 can first generate corresponding scheduling information such as scheduling-DCI1A', wherein the scheduling information scheduling-DCI1A' includes the identification information and the uplink resource allocation information, for example, the bit value corresponding to "pair scheduling usage" in scheduling-DCI1A' is "1" ( Here, the value of the bit shows the identification information, such as "1" or "0" can be predetermined to indicate whether the paired scheduling is used), the value of the bit in "uplink resource block allocation" in scheduling-DCI1A' is "011" (here, the value of the bit shows the number of PRBs in the uplink resource allocation information, because the "uplink resource block allocation" in the above-mentioned DCI1A' occupies 3 bits, and in step S2, base station 1 first The determined uplink resource allocation information is 3PRBs, therefore, the number of bits here is "011"); Then, in step S2, base station 1 sends the scheduling information scheduling-DCI1A through a mobile network such as LTE (Long Term Evolution) 'Send to the mobile device 2, so as to send the identification information and the uplink resource allocation information to the mobile device 2. Here, the manner of showing the identification information and the uplink resource allocation information in the DCI information is only an example, and other existing or future possible ways of showing the identification information and the uplink resource allocation information in the DCI information The way of distributing information, if applicable to the present invention, should also be included in the protection scope of the present invention, and is hereby incorporated by reference.

Here, the present invention enables the base station to allocate the uplink and downlink resources in the same resource allocation message by sending the identification information of the pairing scheduling and the uplink resource allocation information of the uplink response message corresponding to the downlink message to the mobile equipment performing the pairing scheduling. resources to achieve the beneficial effect of reducing signaling overhead, which can save 50% of signaling overhead.

Preferably, when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device, in step S2, the base station 1 may first determine the uplink response corresponding to the downlink message about the mobile device The uplink resource allocation information of the message, so as to send the uplink resource allocation information to the mobile device; or, when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device, in step S2, The base station 1 may first generate corresponding second scheduling information, wherein the second scheduling information includes identification information for performing pair scheduling on the mobile device; then, send the second scheduling information to the mobile device, to send the identification information to the mobile device.

Specifically, when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device, in step S2, the base station 1 may first determine the uplink response corresponding to the downlink message about the mobile device Uplink resource allocation information of the message. Here, in step S2, the manner in which the base station 1 determines the uplink resource allocation information is the same or basically the same as the manner in which the base station 1 determines the uplink resource allocation information in step S2 described above. Again, it is incorporated herein by reference.

Then, in step S2, the base station 1 sends the uplink resource allocation information to the mobile device, such as generating corresponding system information according to the uplink resource allocation information, wherein the system information includes the uplink resource allocation information; Then, broadcast the system information to the mobile device, so as to send the uplink resource allocation information to the mobile device. For example, for mobile device 2, assuming that in step S1, base station 1 determines that mobile device 2 meets the scheduling trigger condition, then when base station 1 receives a new downlink message from a higher layer such as RRC, in step S2, base station 1 first It is determined that the uplink resource assignment information of the uplink response message corresponding to the downlink message on the mobile device 2 is ULresource assignment=3PRBs, then in step S2, the base station 1 can generate a corresponding system message according to the uplink resource assignment information such as SIB, the system information SIB includes the uplink resource assignment information UL resource assignment=3PRBs; then, in step S2, the base station 1 periodically broadcasts the system information SIB to the mobile device 2 through a mobile network such as LTE.

Alternatively, when the scheduling trigger condition is met and the base station sends a downlink message to the mobile device, in step S2, the base station 1 may first generate corresponding second scheduling information, wherein the second scheduling information includes The identification information of the mobile device performing pairing scheduling; and then, sending the second scheduling information to the mobile device, so as to send the identification information to the mobile device. For example, following the above example, in step S1, the base station 1 determines that the mobile device 2 satisfies the scheduling trigger condition, assuming that the base station 1 chooses to use the above-mentioned DCI format 1' to send the identification information and the uplink resource to the mobile device 2 allocation information, then in step S2, base station 1 may first generate corresponding second scheduling information such as scheduling-DCI1', wherein the second scheduling information scheduling-DCI1' includes the identification information, such as "scheduling-DCI1'" The bit value corresponding to "Pairing Scheduling Use" is "1"; then, in step S2, the base station 1 sends the second scheduling information scheduling-DCI1' to the mobile device 2 through a mobile network such as LTE, so as to transmit the The identification information is sent to the mobile device 2 .

Here, the present invention sends the identification information only in the scheduling information (that is, only in the DCI information), and sends the uplink resource allocation information in the system message (such as in the SIB), so that the DCI information is used for uplink resource allocation The bits of the DCI information can be reduced to the minimum, that is, the number of bits of the DCI information is reduced, and the beneficial effect of further reducing signaling overhead is achieved.

Here, those skilled in the art should understand that the present invention may also only send the uplink resource allocation information in scheduling information (that is, only DCI information), and send the identification information in system information (such as SIB).

Preferably, the pair scheduling in the present invention can be used together with dynamic scheduling and continuous scheduling of data. Mobile device 2 can use a scheduling request (SR, Scheduling Request) to request additional resources for uplink transmission, and base station 1 can also schedule mobile device 2 in one direction, uplink or downlink, when scheduling in that direction is needed.

Preferably, the pairing scheduling of the mobile device in the present invention can be predetermined, or configured by a high-level message; the signaling message pair used in the pairing scheduling can be defined in the standard, or be related to the resource quantity allocated for the corresponding uplink response message Together they are indicated in system messages such as SIBs.

Correspondingly, the mobile device 2 receives the identification information for pairing scheduling of the mobile device 2 sent by the base station 1 serving the mobile device 2 through a mobile network such as LTE, and the base station 1 sends a downlink message to the mobile device 2 The message is the determined uplink resource allocation information of the uplink response message corresponding to the downlink message about the mobile device 2 .

In step S3, the mobile device 2 transmits the uplink response message to the base station 1 according to the identification information and based on the uplink resource allocation information. For example, for the mobile device 2, it is assumed that in step S2 it receives the identification information for pairing scheduling of the mobile device 2 sent by the base station 1 serving the mobile device 2, such as the scheduling information sent by the base station 1 in step S2 In scheduling-DCI1A', the value of the bit corresponding to the "pairing scheduling use" of the identification information is "1", and the information about the mobile device 2 determined when the base station 1 sends a downlink message to the mobile device 2 The uplink resource allocation information of the uplink response message corresponding to the downlink message, such as the base station 1 sending a downlink message to the mobile device 2 indicated in the scheduling information scheduling-DCI1A' sent by the base station 1 in step S2 The uplink resource allocation information about the uplink response message "RRC establishment complete" of the mobile device 2 corresponding to the downlink message "RRC connection establishment" determined when "RRC connection establishment" is determined, such as "uplink resource block allocation" in scheduling-DCI1A' The bit value in " is "011", then in step S3, the mobile device 2 sends an uplink response message "RRC establishment complete" on the 3 PRBs continuously allocated in the frequency domain according to the identification information, or, in the predetermined After the delay time, an uplink response message "RRC establishment complete" is sent on the 3 PRBs continuously allocated in the frequency domain.

As another example, assume that the mobile device 2 receives in step S2 the identification information for pairing scheduling of the mobile device 2 sent by the base station 1 serving the mobile device 2, such as the scheduling information sent by the base station 1 in step S2. In DCI1A', the value of the bit corresponding to the "use of pairing scheduling" of the identification information is "1", and the connection between the mobile device 2 and the mobile device 2 determined when the base station 1 sends the downlink message "RRC connection establishment" to the mobile device 2 The uplink resource allocation information of the uplink response message "RRC establishment complete" corresponding to the downlink message "RRC connection establishment", the uplink resource allocation information is shown in Figure 4, wherein the uplink resource allocation information includes: 1) Uplink response message The offset information offset between the first physical resource block corresponding to "RRC establishment complete" and the first physical resource block corresponding to the downlink message "RRC connection establishment"; 2) the uplink response message "RRC establishment complete" and the downlink message The time interval information timing between "RRC connection establishment"; 3) The resource block number information corresponding to the uplink response message "RRC establishment complete", such as 3PRBs, then in step S3, the mobile device 2 can use the offset information offset Determine the starting position of the PRB for sending the uplink response message "RRC establishment complete", and after the time interval timing, send the uplink response message "RRC establishment complete" on the 3 PRBs continuously allocated in the frequency domain starting from the starting position.

The various steps of the base station 1 and the mobile device 2 are continuously working. Specifically, in step S1, the base station 1 continuously detects whether the mobile device 2 served by the base station 1 satisfies the scheduling trigger condition for pair scheduling; when the scheduling trigger condition is met and the base station sends a downlink message, in step S2, the base station 1 continues to determine the uplink resource allocation information of the uplink response message corresponding to the downlink message about the mobile device 2, so as to use the identification information for pairing scheduling of the mobile device 2 And the uplink resource allocation information is sent to the mobile device 2; correspondingly, the mobile device 2 continues to receive the identification information for performing pairing scheduling on the mobile device 2 sent by the base station 1 serving the mobile device 2, and the The uplink resource allocation information of the uplink response message corresponding to the downlink message of the mobile device 2 determined when the base station 1 sends the downlink message to the mobile device 2; in step S3, the mobile device 2 continues to The identification information is used to transmit the uplink response message to the base station 1 based on the uplink resource allocation information. Those skilled in the art should understand that "continuous" means that the steps of the base station 1 and the mobile device 2 respectively continuously detect whether the trigger conditions for pairing scheduling are met, send and receive identification information for pairing scheduling, and uplink resource allocation information 1.

Fig. 7 shows a flowchart of a method for transmitting an uplink response message according to a preferred embodiment of the present invention.

Wherein, the method includes step S1' and step S2', wherein step S2' includes step S21' and step S22'. Specifically, in step S1', the base station 1 detects whether the mobile device 2 served by the base station 1 satisfies the scheduling trigger condition for pair scheduling; when the scheduling trigger condition is met and the base station sends a downlink message, in step S21', base station 1 determines the uplink resource allocation information of the uplink response message corresponding to the downlink message about the mobile device; in step S22', base station 1 will perform The identification information of pair scheduling and the uplink resource allocation information are sent to the mobile device. Here, the content of step S1' is the same or substantially the same as that of the corresponding step in the specific embodiment of FIG.

Specifically, when the scheduling trigger condition is satisfied and the base station sends a downlink message to the mobile device, in step S21', the base station 1 determines an uplink response message corresponding to the downlink message about the mobile device Uplink resource allocation information. Here, in step S21', the way for base station 1 to determine the uplink resource allocation information includes but not limited to at least any of the following:

1) According to the device type information of the mobile device, determine the uplink resource allocation information of the uplink response message corresponding to the downlink message about the mobile device. Here, the device type information includes, but is not limited to, low-cost type devices, high-cost type devices, and the like. For example, for the mobile device 2, assuming that in step S1', the base station 1 determines that the mobile device 2 satisfies the scheduling trigger condition, then when the base station 1 receives a new downlink message from a higher layer such as RRC, if the base station 1 sends a message to the mobile device 2 Send the downlink message as shown in Figure 1, such as "RRC connection establishment", because the uplink response message "RRC establishment complete" and "RRC connection establishment" as shown in Figure 1 are paired messages, then base station 1 can predict that the mobile device 2 Responding to the downlink message "RRC Connection Establishment", that is, sending the uplink resource allocation information when "RRC establishment is complete" to the base station 1, such as predicting the uplink response message "RRC connection" to be sent according to the capabilities of the mobile device 2 and the stored information. Which parameters are available and which parameters are not used in "establishment complete", so as to estimate the number of bits in the uplink response message "RRC establishment complete", and then calculate the required uplink resource allocation information, that is, the required number of PRBs, assuming The mobile device is a low-cost device. For the uplink response message "RRC establishment complete", registeredMME is an option. If the system has only one MME (Mobility Management Entity) or all mobile devices accessing base station 1 use For a certain MME, for the uplink response message "RRC establishment complete", the registeredMME parameter may not be sent, then in step S21', base station 1 may first determine that the number of bits in the uplink response message "RRC establishment complete" is minus the registeredMME parameter The number of bits after the bit, that is, 17+ fixed MAC and RLC headers are required; then, the MCS (modulation and coding scheme, Modulation and Coding Scheme) is determined according to the bit error rate performance, and then according to the number of bits that can be transmitted by each PRB, and then Determine the required number of PRBs, if it is 2PRBs, that is, in step S21', the base station 1 determines that the uplink resource allocation information is 2PRBs.

2) According to the historical uplink resource allocation information of the mobile equipment, determine the uplink resource allocation information of the uplink response message corresponding to the downlink message about the mobile equipment. For example, assuming that in step S1', base station 1 determines that mobile device 2 satisfies the scheduling trigger condition, when base station 1 receives a new downlink message from a higher layer such as RRC, base station 1 sends mobile device 2 a message as shown in Figure 1. The downlink message shown is "When RRC connection is established", because the uplink response message "RRC establishment complete" and "RRC connection establishment" shown in Figure 1 are paired messages, then base station 1 can predict that mobile device 2 will respond to the downlink message " RRC connection establishment" is the uplink resource allocation information sent to base station 1 when "RRC establishment is completed". Assume that when mobile device 2 historically sends "RRC establishment complete" to base station 1, the uplink response message allocated by base station 1 to mobile device 2 The historical uplink resource allocation information is 3PRBs, then when the base station 1 performs pairing scheduling on the mobile device 2 and the base station 1 sends the downlink message "RRC connection establishment" to the mobile device 2, in step S21', the base station 1 can determine the 2. The uplink resource assignment information of the uplink response message corresponding to the downlink message is UL resource assignment=3PRBs.

Those skilled in the art should understand that the above method of determining the uplink resource allocation information is only an example, and other existing or future possible methods of determining the uplink resource allocation information, if applicable to the present invention, should also be included in the within the scope of this invention and is hereby incorporated by reference.

In step S22', the base station 1 sends the identification information for performing pair scheduling on the mobile device and the uplink resource allocation information to the mobile device. Here, in step S22', the way for the base station 1 to send the identification information and the uplink resource allocation information includes but not limited to at least any of the following:

1) First generate corresponding system information, where the system information includes identification information for performing pair scheduling on the mobile device and the uplink resource allocation information; then, broadcast the system information to the mobile device to sending the identification information and the uplink resource allocation information to the mobile equipment. For example, following the above example, in step S21', the base station 1 determines that the uplink resource allocation information of the uplink response message corresponding to the downlink message of the mobile device 2 is UL resource assignment=3PRBs, then in step S22', The base station 1 can first generate a corresponding system information such as SIB', the system information SIB' includes identification information for pairing scheduling of the mobile device 2, such as improving the system information SIB in the prior art, to obtain a system suitable for the present invention The message SIB', such as first adding information "pairing scheduling use -1 bit" in the SIB to obtain SIB', wherein the "pairing scheduling use" bit is used to indicate whether the pairing scheduling is used, that is, it reflects the identification information , for example, "1" or "0" can be predetermined to indicate whether the paired scheduling is used, and at the same time, the uplink resource assignment information UL resourceassignment=3PRBs is added to the SIB; then, in step S22', the base station 1 passes such as mobile The network, such as LTE, periodically broadcasts the system message SIB' to the mobile device 2 .

2) First generate corresponding first scheduling information, where the first scheduling information includes identification information for performing pair scheduling on the mobile device, and the uplink resource allocation information; then, send the first scheduling information to the mobile device, so as to send the identification information and the uplink resource allocation information to the mobile device. For example, following the above example, assuming that the base station 1 chooses to use the above-mentioned DCI format 1C' to send the identification information and the uplink resource allocation information to the mobile device 2, then in step S22', the base station 1 can first generate the corresponding first Scheduling information such as scheduling-DCI1C', wherein the first scheduling information scheduling-DCI1C' includes the identification information and the uplink resource allocation information, such as the bit value corresponding to "pair scheduling use" in scheduling-DCI1C' "1" (here, the value of the bit shows the identification information, such as "1" or "0" can be predetermined to indicate whether the paired scheduling is used), "uplink resource block allocation" in scheduling-DCI1C' The value of the bit in is "011" (here, the value of the bit shows the number of PRBs in the uplink resource allocation information, because the "uplink resource block allocation" in the above-mentioned DCI1C' occupies 3 bits, and in step S21 ', the uplink resource allocation information firstly determined by base station 1 is 3PRBs, therefore, the bit number value here is "011"); then, in step S22', base station 1 uses the mobile network such as LTE to schedule the first The information scheduling-DCI1C' is sent to the mobile device 2, so as to send the identification information and the uplink resource allocation information to the mobile device 2.
