Detailed ways

The embodiments of the present application are applicable to various types of communication systems. FIG. 1 is a schematic diagram of a communication system provided by an embodiment of the present application, which includes a network device 11 and a terminal device 12 such as user equipment (User Equipment, UE), wherein the network device 11 may be a network side device, such as a wireless security True (Wireless-Fidelity, Wi-Fi) access point AP, the base station of next-generation communication, such as 5G gNB or small station, micro station, it can also be a relay station, access point, vehicle-mounted equipment, etc. The terminal device 12 in the embodiment of the present application may refer to an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a user agent or a user device. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant , referred to as "PDA"), handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminals in 5G networks, stations in next-generation WIFI (Station, STA) etc.

In a Long Term Evolution (LTE) system, the network device allocates scheduling request (Scheduling Request, SR) resources to the terminal device, and the terminal device can apply for uplink scheduling resources to the network device by sending an SR on the SR resource, and Traditional mobile broadband (Mobile Broad Band, MBB) service data is sent on the uplink scheduling resource allocated by the network device to the terminal device.

In the 5G network, the Ultra Reliable Low Latency Communications (URLLC) service is introduced. This service requires that the data transmission delay is less than 0.5ms, and the probability of successful data transmission is greater than or equal to 99.999%. This requirement is much stricter than the existing Long Term Evolution (Long Term Evolution, LTE) system. In order to meet the requirements of the URLLC service, the data of the URLLC service can be transmitted uplink using Grant-free resources.

FIG. 2 is a schematic diagram of a method for sending MBB service data provided by an embodiment of the present application. As shown in Figure 2, when the MBB service data arrives at the radio access network (Radio Access Network, RAN for short) side of the UE, the UE starts to wait for a scheduling request (Scheduling Request, SR for short) resource, and the SR resource is provided by the base station for each UE. A dedicated resource allocated. The period of SR is configured through the sr-Config Index field of IE: Scheduling Request Config, and the base station can send SR resources on physical uplink control channel (Physical Uplink Control Channel, PUCCH) format 1 resources. When the UE receives the SR resource from the base station, it sends an SR on the SR resource to tell the base station that the UE has data to send. After receiving the SR, the base station allocates a small part of uplink resources to the UE. The resources are sufficient for the UE to send a buffer status report (Buffer Status Reports, BSR), and then the base station issues an uplink scheduling authorization UL grant to the UE. The UL grant is used to indicate at which time, which carrier and which modulation and coding method the UE can upload the BSR. The uplink resource indicated by the UL grant sends a BSR to the base station to tell the base station how much data the UE has to send. After receiving the BSR, the base station allocates uplink resources to the UE again and sends a UL grant to the UE. At this time, the UL grant is used to indicate At which time, which carrier and which modulation and coding mode the UE can upload the MBB service data, and the UE sends the MBB service data to the base station according to the uplink resource indicated by the UL grant.

As shown in Figure 3, if the UE does not receive the UL grant issued by the base station after sending the SR to the base station, the UE can continue to send the SR at the next SR opportunity until the number of SRs sent by the UE reaches a certain number of times (for example, 6 times) , the embodiment of the present application does not limit the specific number of times) before receiving the UL grant from the base station, the UE will initiate random access on the next physical random access channel (Physical Random Access Channel, PRACH) resource ( Random Access, RA) process.

Since the terminal device can correspond to data of various services, the types of uplink resources required by the terminal device to send different service data are different. However, in the prior art, the terminal device cannot apply for different types of uplink resources from the network device. In order to solve this problem, the embodiment of this application provides a resource application method, specifically provides the following several embodiments, and the following describes the embodiments in combination with specific scenarios:

FIG. 4 is a schematic flowchart of a method for resource application provided by an embodiment of the present application. The method described in the embodiment of this application is not only applicable to the 5G system, as long as the uplink resource needs to be allocated by one of the communication parties, the method described in the embodiment of the application can be used. The following uses the 5G system as an example to introduce the resource application method, as follows As shown in Figure 4, the method specifically includes the following steps:

Step S401, the terminal device determines the first type of uplink resource applied for from the network device.

Wherein, a feasible implementation manner for the terminal device to determine the first type of uplink resources applied for from the network device is: the terminal device determines the first logical channel that triggers the process of the first indication information, and the first indication information uses To indicate the amount of data to be transmitted by the terminal device; the terminal device determines at least one first type from at least one type of uplink resource corresponding to the first logical channel.

As shown in FIG. 5, a terminal device such as a UE has four logical channels (Logical Channel, LCH), and the four logical channels are LCH1, LCH2, LCH3, and LCH4 respectively, wherein the priorities of LCH1, LCH2, LCH3, and LCH4 are in order The reduction is only a schematic illustration here, and does not limit the number of logical channels of the terminal equipment. In order to distinguish different logical channels, the first logical channel in this embodiment may specifically be LCH2, and the second logical channel appearing in subsequent embodiments may specifically be LCH1.

Specifically, LCH1, LCH2, LCH3, and LCH4 correspond to different buffer areas of the terminal device, and the priorities of the data cached in different buffer areas are different, so the priorities of the data in the buffer areas corresponding to LCH1, LCH2, LCH3, and LCH4 respectively decrease in turn. . When data arrives at the buffer area corresponding to the first logical channel, the process of the first indication information is triggered. The first indication information may be specifically BSR. For example, when data arrives at the buffer area corresponding to LCH2, a BSR process is triggered. At this time The BSR is used to indicate the amount of data to be sent by a terminal device such as a UE after the data arrives at the buffer area corresponding to LCH2. The data to be sent may be the sum of the data in the buffer areas corresponding to the four logical channels.

In addition, each logical channel corresponds to its own uplink resource type, and the uplink resource type includes but is not limited to an air interface format or a transmission time interval (Transmission Time Interval, TTI) length, wherein the correspondence between the logical channel and the uplink resource type is given by Configured by the base station, the air interface format includes at least one of subcarrier spacing, cyclic prefix (CyclicPrefix, CP) length, and TTI length. As shown in Figure 5, LCH2 corresponds to three different air interface formats or TTI lengths. The three different air interface formats or TTI lengths are respectively recorded as: air interface format or TTI length 2A, air interface format or TTI length 2B, air interface format or TTI length 2C, 2A, 2B, and 2C can be used as identification information of three different air interface formats or TTI lengths.

For example, when the buffer corresponding to LCH2 has data arriving and the buffer corresponding to LCH1 has no data, it is LCH2 that triggers the BSR process. At this time, LCH2 is the LCH with the highest priority that triggers the BSR process. Since the first logical channel can specifically It is LCH2. In order to distinguish it from the second logical channel such as LCH1 involved in subsequent embodiments, the BSR process triggered by LCH2 can be recorded as BSR process A here, and the BSR process triggered by LCH1 in subsequent embodiments can be recorded as BSR process b. A terminal device such as a UE selects an air interface format or TTI length from three different air interface formats or TTI lengths corresponding to LCH2 as the type of uplink resources that a terminal device such as a UE applies to the base station, for example, a terminal device such as a UE media access The control (Media Access Control, MAC) layer entity selects the air interface format or TTI length 2A from the air interface format or TTI length 2A, the air interface format or TTI length 2B, the air interface format or TTI length 2C, the first type described in this embodiment Specifically, it is an air interface format or a TTI length of 2A, indicating that a terminal device such as a UE requires that the type of uplink resources allocated by the base station to the UE be the type identified by 2A.

Step S402, the terminal device selects a first target resource from the scheduling request resources, and indicates the first type of the uplink resource through the first target resource.

As shown in Figure 5, SR resources appear periodically, and the air interface format or TTI length that each SR resource can indicate can be the same or different. For example, the first SR resource can indicate the air interface format or TTI length 2A or the air interface format or TTI Length 2B, the second SR resource can indicate the air interface format or TTI length 2A or the air interface format or TTI length 2C, and the subsequent SR resources will not be described again. Since a terminal device such as a UE determines that the type of uplink resource that needs to be allocated by the base station to the UE is the type identified by 2A, that is, the air interface format or TTI length 2A, the MAC layer entity selects from the periodically occurring SR resources that can indicate the air interface format or TTI length 2A SR resource, and record the SR resource that can indicate the first type, that is, the air interface format or TTI length 2A, as the first target resource. As shown in Figure 5, the first SR resource, the second SR resource, the fourth The SR resource and the fifth SR resource can indicate the air interface format or TTI length 2A. Therefore, the first SR resource, the second SR resource, the fourth SR resource, and the fifth SR resource are used as the first target resource, such as The shaded part of the vertical line shown in Figure 5.

Step S403, the terminal device sends first scheduling request information on the first target resource, the first scheduling request information is used to request the network device to allocate the first type of uplink resource to the terminal device .

After the MAC layer entity selects the first target resource, it notifies the UE's physical layer entity to send scheduling request information on the first SR resource, the second SR resource, the fourth SR resource, and the fifth SR resource, such as SR information In this embodiment, the first type of the uplink resource is indicated by the first target resource, specifically including the following possible situations:

A possible situation is: the time-frequency position where the first target resource appears. The time-frequency position may specifically be at least one of time and frequency domain positions, and may indicate the first type of uplink resources that the base station is requested to allocate to the UE, for example, The timings at which the first SR resource, the second SR resource, the fourth SR resource, and the fifth SR resource appear respectively may indicate that the type of the uplink resource allocated to the UE by the requesting base station is 2A. Specifically, the MAC layer entity notifies the physical layer entity to send an SR to the base station on the corresponding SR resource when the first SR resource, the second SR resource, the fourth SR resource, and the fifth SR resource respectively appear.

Another possible situation is: the first scheduling request information sent by the UE on the first target resource includes identification information of the type of uplink resources that the base station is requested to allocate to the UE, for example, the UE is on the first SR resource, the second The SR sent on the SR resource, the fourth SR resource, and the fifth SR resource respectively include the identification information of the air interface format or TTI length 2A, that is, 2A, because the first SR resource, the second SR resource, and the fourth SR resource resource, the fifth SR resource can not only indicate the air interface format or TTI length 2A, but also indicate the air interface format or TTI length 2B or 2C, therefore, in the first SR resource, the second SR resource, the fourth SR resource, When sending an SR on the fifth SR resource, the identification information 2A needs to be carried in the SR to indicate the air interface format actually indicated by the first SR resource, the second SR resource, the fourth SR resource, and the fifth SR resource or The TTI length is 2A instead of 2B or 2C.

As shown in Figure 5, the MAC layer entity selects an air interface format or TTI length 2A from the air interface format or TTI length 2A, the air interface format or TTI length 2B, the air interface format or TTI length 2C, in other embodiments, the MAC layer The entity can also choose multiple air interface formats or TTI lengths. As shown in Figure 6, the MAC layer entity selects two air interface formats or TTI length, specifically air interface format or TTI length 2A and air interface format or TTI length 2B. At this time, the first type can be air interface format or TTI length 2A and air interface format or TTI length 2B, that is, the number of the first type can be One, or more than one. If there are multiple first types, the first target resource indicates one of the multiple first types.

After the MAC layer entity selects the air interface format or TTI length 2A and the air interface format or TTI length 2B, it selects the SR resources that can indicate the air interface format or TTI length 2A or the air interface format or TTI length 2B from the SR resources that appear periodically, such as As shown in Figure 6, the first SR resource, the second SR resource, the fourth SR resource, and the fifth SR resource can indicate the air interface format or TTI length 2A, and the first SR resource, the third SR resource, and the Four SR resources, the seventh SR resource can indicate the air interface format or TTI length 2B, where the first SR resource can indicate either the air interface format or TTI length 2A, or the air interface format or TTI length 2B, the fourth SR resource The resource can indicate either the air interface format or TTI length 2A, or the air interface format or TTI length 2B. In this case, it can be determined which one the first SR resource and the fourth SR resource indicate through the following feasible implementation methods: Air interface format or TTI length:

A feasible implementation method is: from the air interface format or TTI length 2A and the air interface format or TTI length 2B, randomly select an air interface format or TTI length as the air interface format that the first SR resource and the fourth SR resource can indicate. TTI length.

Another feasible implementation method is: according to the priority of the air interface format or TTI length 2A, air interface format or TTI length 2B, air interface format or TTI length 2C corresponding to LCH2, determine the priority of the first SR resource and the fourth SR resource Indicate which air interface format or TTI length, optional, air interface format or TTI length 2A, air interface format or TTI length 2B, air interface format or TTI length 2C have priority in descending order, then the first SR resource and the fourth SR resource It can preferentially indicate the air interface format or TTI length 2A.

Therefore, as shown in FIG. 6, the MAC layer entity notifies the physical layer entity that the SRs sent on the first SR resource, the second SR resource, the fourth SR resource, and the fifth SR resource carry identification information 2A. The SR sent on three SR resources and the seventh SR resource carries identification information 2B. The first target resource in this embodiment may specifically be the SR resource in the shaded part of the vertical line as shown in FIG. 6 . Among them, the MAC layer entity does not notify the physical layer entity to send an SR on the sixth SR resource, because the sixth SR resource can indicate the air interface format or TTI length 2C, that is, it can request the base station for the air interface format or the uplink with a TTI length of 2C resource, so the MAC layer entity does not notify the physical layer entity to send an SR on the sixth SR resource.

In addition, the terminal device determines at least one first type from at least one type of uplink resource corresponding to the first logical channel, including the following several feasible implementation manners:

A feasible implementation manner is: the terminal device selects an uplink resource type with the highest priority as the first type from at least one type of uplink resource corresponding to the first logical channel. The priority here can be obtained in three ways: one method is stipulated by the protocol, and the criterion for judging the priority of all UEs is the same; the other way is indicated through broadcast messages, and the criterion for judging the priority of all UEs is the same; Yet another way is configured by dedicated signaling, and each UE has different criteria for judging the priority.

Another feasible implementation manner is: the terminal device randomly selects an uplink resource type from at least one uplink resource type corresponding to the first logical channel as the first type.

Another feasible implementation manner is: the terminal device selects an uplink resource type with the shortest transmission time interval from at least one type of uplink resource corresponding to the first logical channel as the first type.

Yet another feasible implementation manner is: the terminal device selects an uplink resource type with the highest reliability from at least one type of uplink resource corresponding to the first logical channel as the first type.

Another feasible implementation manner is: the terminal device selects an uplink resource type with the densest scheduling request resource as the first type from at least one type of uplink resource corresponding to the first logical channel.

Another feasible implementation manner is: the terminal device selects, from at least one type of uplink resource type corresponding to the first logical channel, an uplink resource type whose corresponding scheduling request resource arrives earliest as the first type.

Wherein, the first logical channel may specifically be the LCH2 described in the foregoing embodiment. The at least uplink resource type corresponding to the first logical channel may specifically be the air interface format or TTI length 2A, the air interface format or TTI length 2B, and the air interface format or TTI length 2C corresponding to the LCH2 described in the above embodiments. The first type may specifically be the air interface format or TTI length 2A described in the above embodiments, or the air interface format or TTI length 2A and the air interface format or TTI length 2B, that is, the first type may be an air interface format or TTI length, or It can be multiple air interface formats or TTI lengths.

In the resource application method provided in this embodiment, the terminal device determines the type of uplink resource applied to the network device, selects a target resource that can indicate the type from the scheduling request resources, and sends scheduling request information on the target resource, so as to Requesting the network device to allocate this type of uplink resource to the terminal device realizes the mechanism that the terminal device can apply for different types of uplink resources from the network device.

On the basis of the above embodiments, when the terminal device sends the first scheduling request information on the first target resource, data arrives at the buffer corresponding to the second logical channel, and triggers the process of the second indication information, so The second indication information is used to indicate the amount of data to be transmitted by the terminal device after the data arrives in the cache corresponding to the second logical channel.

Wherein, the first logical channel may specifically be the LCH2 described in the above embodiment, the second logical channel may specifically be the LCH1 described in the above embodiment, and the first target resource is the shaded part of the vertical line as shown in Figure 5 or 6 SR resource, the first scheduling request information is the SR sent on the first target resource. As shown in Figure 5 or 6, during the process of the physical layer entity sending an SR on the SR resource in the shaded part of the vertical line, for example, when the third SR is sent, new data arrives at the cache corresponding to LCH1. If the priority is higher than that of LCH2, the priority of the new data arriving at the cache corresponding to LCH1 is higher than that of the data arriving at the cache corresponding to LCH2 in the above embodiment. This is only a schematic illustration and does not limit the The priority is higher than that of LCH2, and the priority of LCH1 can be lower than that of LCH2, or, the priority of LCH1 is equal to that of LCH2, and both LCH1 will trigger BSR process B, and LCH1 becomes the triggering BSR process the LCH with the highest priority, the terminal device performs the following steps:

determining, by the terminal device, a second type of uplink resource applied to the network device from at least one type of uplink resource corresponding to the second logical channel;

The terminal device selects a second target resource from the scheduling request resources, and indicates the second type of the uplink resource through the second target resource;

The terminal device sends second scheduling request information on the second target resource, where the second scheduling request information is used to request the network device to allocate the second type of uplink resource to the terminal device.

Wherein, the number of the second type is multiple, and the second target resource indicates one of the multiple second types. The aforementioned steps will be described in detail below with reference to FIG. 7 .

As shown in Figure 7, LCH1 corresponds to two different air interface formats or TTI lengths, namely air interface format or TTI length 1A and air interface format or TTI length 2A. What needs to be explained here is that the air interface format or TTI length corresponding to each LCH The number and type of can be pre-configured. The MAC layer entity determines the second type of uplink resource applied to the network device from the two different air interface formats or TTI lengths corresponding to LCH1. The second type can be one or multiple. Optionally, the first The second type is air interface format or TTI length 1A or air interface format or TTI length 2A. Since the new data arrives at the buffer corresponding to LCH1 when the physical layer entity sends the third SR, starting from the fourth SR resource, the MAC layer entity selects from the periodically occurring SR resources that can indicate the air interface format or TTI length 1A Or air interface format or SR resource with TTI length 2A, and record the SR resource that can indicate air interface format or TTI length 1A or air interface format or TTI length 2A as the second target resource, as shown in Figure 7, the fourth SR resource can be Indicate the air interface format or TTI length 2A, the fifth SR resource can indicate the air interface format or TTI length 1A, and the sixth SR resource can indicate the air interface format or TTI length 2A, then the fourth SR resource, fifth SR resource, The sixth SR resource is recorded as the second target resource, as shown in the shaded part of the horizontal line in FIG. 7 . If an SR resource can indicate either the air interface format or TTI length 1A, or the air interface format or TTI length 2A, the priority of the air interface format or TTI length 1A is higher than that of the air interface format or TTI length 2A. The SR resource preferably indicates the air interface format or TTI length 1A, and can also randomly select one from the indicated air interface format or TTI length 1A and the indicated air interface format or TTI length 2A as the air interface format or TTI length indicated by the SR resource. After the MAC layer entity determines the second target resource, it sends the second scheduling request information on the second target resource. For example, when sending SR on the fourth SR resource and the sixth SR resource, the SR needs to carry identification information 2A , to indicate that the air interface format or TTI length actually indicated by the fourth SR resource and the sixth SR resource is 2A, indicating that the UE needs the type of uplink resource allocated by the base station to the UE to be the type identified by 2A; on the fifth SR resource When sending an SR, it is necessary to carry the identification information 1A in the SR, to indicate that the air interface format or TTI length actually indicated by the fifth SR resource is 1A, and to indicate that the type of uplink resources allocated by the UE to the UE by the base station is the type identified by 1A. Since the seventh SR resource can indicate the air interface format or TTI length of 2C, that is, the uplink resource with the air interface format or TTI length of 2C can be requested from the base station, and the air interface format or TTI length of 2C is not the air interface format or TTI length corresponding to LCH1, so , the MAC layer entity does not notify the physical layer entity to send an SR on the seventh SR resource.

On the basis of the above embodiments, the first indication information corresponds to the process of the first scheduling request, the second indication information corresponds to the process of the second scheduling request, and the priority of the process of the second scheduling request is higher than that of the scheduling request. The priority of the process of the first scheduling request. The first indication information refers to the amount of data to be sent by the UE after the data arrives in the buffer area corresponding to LCH2, that is, the BSR. The second indication information refers to the amount of data to be sent by the UE after the data arrives in the buffer area corresponding to LCH1, that is, the BSR. The process of the scheduling request may specifically be the first SR process, and the process of the second scheduling request may specifically be the second SR process. In this embodiment, it may be determined whether process 2 needs to be triggered in the following implementable manner. Specifically, the terminal device According to the first time window corresponding to the first scheduling request information and the second time window corresponding to the second scheduling request information, determine whether to trigger the process of the second scheduling request; where the first time window is The shortest time interval for the terminal device to send two adjacent first scheduling request messages; the second time window is the shortest time interval for the terminal device to send two adjacent second scheduling request messages. Wherein, the length of the first time window corresponding to the first scheduling request information and the length of the second time window corresponding to the second scheduling request information are configured by the base station, for example, may be configured through RRC.

As shown in Figure 8, arrow A indicates that the first SR process is triggered, arrow B indicates that the first SR process sends an SR, and 81 indicates the time window after the first SR process sends an SR, and there may be SRs in this time window The resource appears, but the first SR process of the UE cannot send SR through the SR resource within the duration of the time window 81, and needs to wait until the end of the time window 81 to send the SR on the first SR resource that appears. Arrow C indicates that the second SR process is assumed to be triggered, and arrow D indicates the moment when the second SR process sends the SR after the second SR process is assumed to be triggered. 82 indicates the time window after the second SR process sends the SR. There are SR resources, but the second SR process of the UE cannot send SR through the SR resources within the duration of the time window 82, and needs to wait until the end of the time window 82 to send the SR on the first SR resource that appears. It can be seen from FIG. 8 that the end time of the time window 82 is earlier than the end time of the time window 81 , in this case, the second SR process is triggered. Optionally, the first SR process may also be stopped.

Arrow E indicates that the second SR process is assumed to be triggered, arrow F indicates the moment when the second SR process sends an SR after the second SR process is assumed to be triggered, and 83 indicates the time window after the second SR process sends an SR. There are SR resources, but the second SR process of the UE cannot send SR through the SR resources within the duration of the time window 83, and needs to wait until the end of the time window 83 to send the SR on the first SR resource that appears. It can be known from FIG. 8 that the end time of the time window 83 is later than the end time of the time window 81 , in this case, the second SR process is not triggered. Optionally, the first SR process may also be continued.

The resource application method provided in this embodiment determines whether the SR process is triggered through a time window, and prevents the old SR process from being unconditionally interrupted by the new SR process.

In addition, on the basis of the foregoing embodiments, the process of the first scheduling request and the process of the second scheduling request may be parallelized, and the parallel here refers to the parallelism of the processes, not the parallelism of the SR resources. As shown in Figure 9, process 1 represents the process of the first scheduling request, process 2 represents the process of the second scheduling request, process 1 and process 2 are parallel, and the count of process 1 is used to count the UE sending the first scheduling request information The number, the counting of the process 2 is used to count the number of second scheduling request information sent by the UE, and the UE counts the number of first scheduling request information and the number of second scheduling request information sent respectively.

In addition, the process of the first scheduling request and the process of the second scheduling request can also be serialized, and the serialization here refers to the serialization of two SR resources, that is, only one process is in progress at the same time, and the other process It can be suspended. The difference between suspending and stopping is that the process may not resume after it stops, but it may resume after the process is suspended. As shown in Figure 10 or 11, when process 2 is triggered, process 1 is suspended; when process 2 is suspended, process 1 is resumed. When the process of the first scheduling request resumes, the terminal device recounts the number of sent first scheduling request information, or counts the number of first scheduling request information sent according to the historical statistics of the number of first scheduling request information number. As shown in FIG. 10 , when process 1 is resumed, on the basis of the historically counted number 4 of first scheduling request information, the number of sent first scheduling request information, such as 5, 6, and 7, continues to be counted. As shown in FIG. 11 , when process 1 is resumed, the number of first scheduling request information is counted from 1 again.

In the resource application method provided by this embodiment, by counting SR processes of different priorities, the SR processes of different priorities can be performed in parallel or serially. Counting, when SRs with different priorities are serialized, the counting of the restored SR process can be restarted, or continue counting from the historical counting basis, which improves the flexibility of counting SR processes.

On the basis of the foregoing embodiments, if the type of the uplink resource indicated by the scheduling request resource includes the first type or the second type, the terminal device counts the progress of the second scheduling request. For example, the process of the second scheduling request, that is, the second SR process, has a higher priority than the process of the first scheduling request, that is, the first SR process. When the first SR process and the second SR process run in parallel, if the same SR Resources can be used by two SR processes at the same time. How to count the two SR processes includes the following feasible implementation methods: counting the high-priority SR processes. As shown in Figure 12, the MAC layer entity determines that the air interface format or TTI length 2A, air interface format or TTI length 2B, and air interface format or TTI length 2C corresponding to LCH2 are all of the first type, that is, it can indicate the air interface format or TTI length 2A, air interface The SR resource with format or TTI length 2B or air interface format or TTI length 2C is recorded as the first target resource, and the SR is sent through the first SR resource, the second SR resource and the third SR resource respectively. SRs sent on a target resource are counted. After the third SR is sent, more advanced data arrives at the cache corresponding to LCH1, then LCH1 triggers a new process 2, process 1 represents the process of the first scheduling request, process 2 represents the process of the second scheduling request, and process 2 The priority of process 1 is higher than that of process 1.

After process 2 is triggered, the fourth SR resource can indicate the air interface format or TTI length 2A, or indicate the air interface format or TTI length 2B, because the air interface format or TTI length 2A belongs to the air interface format or TTI length corresponding to LCH1, and also belongs to LCH2 For the corresponding air interface format or TTI length, since the priority of LCH1 is higher than that of LCH2, the UE counts the SR sent on the fourth SR resource as the first count of process 2, that is, the count of process 2 plus 1, but the count of process 1 does not add 1. Since the fifth SR resource indicates the air interface format or TTI length 1A, and the air interface format or TTI length 1A belongs to the air interface format or TTI length corresponding to LCH1, the count of process 2 is added by 1. The SR sent on the sixth SR resource is counted as the third count of process 2, similar to the fourth SR resource, and the seventh SR resource indicates the air interface format or TTI length 2C, and the air interface format or TTI length 2C does not belong to LCH1 The corresponding air interface format or TTI length belongs to the air interface format or TTI length corresponding to LCH2. Since process 1 and process 2 are parallel, process 1 continues to be counted. This embodiment is limited to the case where there is only one SR resource at the same time. If there are multiple SR resources at the same time, the UE can use multiple SR resources at the same time and request different types of resources from the base station respectively, and the two SR processes are sent at the same time.

The resource application method provided in this embodiment counts the parallel SR processes separately. When the same SR resource can be used by two SR processes at the same time, it can count the high-priority SR processes, avoiding the possibility of SR process counting. error occurred.

In addition, when the number of the second scheduling request information sent by the terminal device or the number of the first scheduling request information is greater than the preset number, the method further includes at least one of the following:

The terminal device initiates a random access procedure; for example, the UE cancels all suspended or pending SR procedures. When initiating a random access process, according to one or more air interface formats or TTI lengths corresponding to the SR-BSR-LCH that has reached the maximum number of times, select the corresponding "PRACH resource + preamble ID" combination to initiate random access. The combination of the time-frequency position of the PRACH resource and the preamble ID can indicate to the network side which air interface format or TTI-length resource.

The terminal device releases at least one of the following first types of uplink resources corresponding to the first logical channel: uplink control channel resources, uplink reference signal resources, uplink data transmission resources, and downlink data transmission resources; or, the The terminal device releases at least one of the following second types of uplink resources corresponding to the second logical channel: uplink control channel resources, uplink reference signal resources, uplink data transmission resources, and downlink data transmission resources. For example, the UE notifies the radio resource control (Radio Access Technology, RRC) layer entity of the UE "the SR process is triggered by the BSR of which LCH", and the RRC layer entity releases one or more SRs corresponding to the LCH according to the information of the LCH. The physical uplink control channel (Physical Uplink Control Channel, PUCCH) resource, channel sounding reference signal (Sounding Reference Signal, SRS) resource, downlink (Down Link, DL) resource and uplink (Uplink) resource corresponding to each air interface format or TTI length Any one or more resources in Link, UL) resources.

In the resource application method provided in this embodiment, when the number of SR transmissions is greater than the preset number of times, resource utilization is improved by releasing resources or initiating random access.

In addition, canceling the SR process includes the following feasible implementation methods:

A feasible implementation manner is: if the type of the uplink resource allocated by the network device includes the first type, the terminal device cancels the first scheduling request process; or if the terminal device receives the If the type of the uplink resource allocated by the network device includes the second type, the second scheduling request process is canceled. For example, the UE receives the uplink resource allocated by the base station, and the air interface format or TTI length of the uplink resource falls within the scope of the SR application. As shown in Figure 12, there are two SR processes, process 1 and process 2. Process 1 is triggered by LCH2, and the resource type it applies for is 2A, 2B, or 2C. Either one can cancel process 1; similarly, process 2 is triggered by LCH1, and the resource type it applies for is 1A or 2A, as long as the UE receives either 1A or 2A allocated by the base station, it can be canceled Process 2.

Another feasible implementation manner is: if the terminal device sends the first indication information to the network device, cancel the first scheduling request process, and the first indication information is used to indicate that the first The amount of data to be transmitted corresponding to the logical channel; or if the terminal device sends second indication information to the network device, cancel the second scheduling request process, and the second indication information is used to indicate the The amount of data to be transmitted corresponding to the second logical channel. For example, the UE sends a BSR, and the BSR includes data to be sent on the LCH or LCH group that currently triggers the SR process. For example, if the UE sends a BSR, and the BSR contains data of the LCH 2, the SR process triggered by the LCH 2 is canceled.

Another feasible implementation is: if the terminal device sends the first indication information to the network device through the uplink resource of the first type or the second type, cancel the first scheduling request process. For example, the UE sends a BSR, and the BSR contains the pending data of the LCH or LCH group currently triggering process 1, and the air interface format or TTI length priority of the uplink resource sending the BSR is higher than or equal to the LCH or LCH If the priority of the air interface format or TTI length corresponding to the group is selected, process 1 is canceled. For example, if the UE sends a BSR, and the BSR contains the data of LCH2, and the BSR is transmitted through the air interface format 2A, 2B, or 2C or a higher priority air interface format, process 1 is canceled.

Another feasible implementation is: if the type of the uplink resource indicated by the combination of the PRACH resource and the preamble ID used when the terminal device initiates the random access procedure includes one or more types corresponding to the first logical channel uplink resource type, then cancel the first scheduling request process;

Another feasible implementation is: if the type of the uplink resource indicated by the combination of the PRACH resource and the preamble ID used when the terminal device initiates the random access procedure includes one or more uplink resource type, cancel the second scheduling request process.
