The present application claims priority to Chinese Patent Application No. 201510460003.8, filed on Jan.

Technical field

The present disclosure relates to the field of communications, and in particular, to a method, an apparatus, a network side device, and a terminal for indicating resource transmission.

Background technique

In the current frame structure of the LTE (Long Term Evolution), the downlink control channel (Downlink Control Information) of the downlink control channel in the downlink control area is used to perform downlink scheduling allocation and uplink scheduling authorization, where the control area is occupied at most. 3 OFDM (Orthogonal Frequency Division Multiplexing) symbols (4 for 1.4 MHz system bandwidth).

The downlink control allocation DCI includes the PDSCH (Physical Downlink Shared Channel) resource indication, the transmission format, and the HARQ (Hybrid Automatic Repeat reQuest) information, which is related to spatial multiplexing. The control information (if spatial multiplexing is used), the downlink scheduling assignment further includes a power control command of the uplink physical channel of the PUCCH (Physical Uplink Control Channel).

The control information included in the uplink scheduling grant DCI includes a PUSCH (Physical Uplink Shared Channel) resource indication, a transport format, and HARQ related information. It also includes power control commands for the PUSCH uplink physical channel.

The terminal obtains the location information of the physical resources scheduled by the user by reading the DCI information carried by the control channel, and further performs corresponding operations of the uplink and downlink data, demodulation, decoding, and the like, and coding and modulation mapping of the uplink data.

As shown in FIG. 1 , in a subframe, the base station indicates, by using a scheduling resource indication, which PRB (Physical Resource Block) resources are occupied by the user in the frequency domain for transmission. For resource mapping, you only need to avoid reference signals such as CRS (Cell-specific Reference Signals), DMRS (Demodulation Reference Signals), and CSI-RS (Channel State Information Reference Signals). The position of the status information reference signal) is sufficient.

With the variety of communication services, there are some small data services or small packet services, which may be transmitted in the LTE frame structure in the related art, as shown in FIG. 2, which is a schematic diagram of the data resources occupied in the subframe. After the packet transmission occupies the transmission resource of the ordinary LTE user, for the ordinary LTE user, the useful data corresponding to the resource location occupied by the packet service will be punctured.

In addition, in the design of a new generation mobile communication 5G frame structure, in order to reduce the delay requirement of feedback, etc., there is a scheme to design a downlink control channel for the first OFDM symbol in one subframe, and an uplink control channel for the last OFDM symbol. Thus, once the last OFDM symbol has control information transmission, it cannot be used by ordinary LTE users to transmit data.

In the frame design of the future 5G, considering the requirement of low delay, a minimum scheduled transmission time unit (for example, a TTI (Transmission Time Interval) length may be further shortened, such as by the current 14 OFDM symbols. Shortened to 1 or 2 OFDM symbols (it is to be noted that the number of OFDM symbols described above is merely exemplary, and the specific number may be determined according to the specific communication system used (for example, 5G mobile communication system).) Users with less data can occupy one TTI, and users with large data volume also need to occupy multiple TTI transmissions, that is, multiple TTI scheduling. As shown in Figure 3, it is a schematic diagram of multi-TTI scheduling. There are two users on the uplink. Multi-TTI scheduling is performed, but one TTI is used to transmit PUCCH, and other users are scheduled by TTI. Among them, since the user does not know the resource occupation in multiple TTIs in advance, user 1 is located in multi-TTI scheduling. The data transmission of the location of the TTI used to transmit the PUCCH is affected.

Step 11: Obtain information about the occupation status of the user resource by the high priority service;

Step 12: Send the user resource information of the high priority service to the terminal by using the control information.

In step 111, the information about the occupation of the high-priority service of the user resource is obtained by the situation that the resource block corresponding to the user resource is occupied by the high-priority service.

Further, the method for transmitting the user resource by the high-priority service occupation situation information to the terminal by using the control information provided in the foregoing embodiment of the present disclosure may include:

Step 121: The user resource is sent to the terminal by the high-priority service occupation information through the public control information of the public control area or the control information of the terminal-specific control area.

Further, the method for transmitting the user resource by the high-priority service occupation situation information to the terminal by using the control information provided in the foregoing embodiment of the present disclosure may include:

Step 122: The N bits added in the control information in the physical downlink control channel are used to indicate the occupation of the resource block corresponding to the user resource.

Step 123: Send control information indicating that the resource block is occupied by the high priority service to the terminal.

Step 1221: In the M resource blocks, the resource blocks actually occupied by the high-priority service are represented by a bitmap by using the added N bits, M=N or

In step 1222, among the M resource blocks, the N resource blocks of the fixed position actually occupied by the high priority service are directly represented by bits, and N is smaller than M.

Specifically, the N resource blocks of the fixed location in step 1222 are distributed in the M resource blocks.

Further, before the high-priority service is fixed in the resource block of the N locations in the step 1222 in the foregoing embodiment of the present disclosure, the method further includes:

Step 1220: The high priority service is transmitted by using a pre-defined or broadcast channel or radio resource control signaling to notify a resource block of a fixed N locations in a resource block corresponding to the user resource.

The following describes the resource block situation that is actually occupied by the high priority service in a bitmap mode in combination with two specific embodiments.

As shown in FIG. 8 , one subframe is composed of N OFDM symbols, and N bits are required in the bitmap to represent resource blocks actually occupied by high-priority services, and 0 can be artificially defined to correspond to resources that are not occupied, and 1 is high. The resources occupied by the priority data. Or the meaning of 0, 1 is exchanged.

From right to left, the resources in the first OFDM symbol and the fourth OFDM symbol are high The first-level service is occupied. The corresponding bit position identifier in the bitmap is “1”, and the remaining bit positions are identified as “0”.

As shown in FIG. 9, when a radio frame is composed of N TTIs, N bits are required in the bitmap to represent resource blocks actually occupied by high-priority services, and 0 can be artificially defined to correspond to resources that are not occupied. Resources used by high priority data. Or the meaning of 0, 1 is exchanged. Those skilled in the art can understand that the above radio frame is merely exemplary, and the disclosure is not limited thereto; in other communication systems different from the LTE communication system, other elements may be used instead of the above-mentioned radio frame as long as it It can represent a higher level of time unit than the basic scheduled transmission unit.

From right to left, the resources in the second OFDM symbol and the fourth OFDM symbol are occupied by the high priority service, the corresponding bit position in the bitmap is identified as "1", and the remaining bit positions are identified as "0".

The following is a detailed description of the manner in which the bit is directly represented to indicate the resource block actually occupied by the high priority service.

As shown in FIG. 10, one subframe is composed of 0 OFDM symbols. First, each subframe has P=2 OFDM symbols, which can be used to transmit high-priority services. The two OFDM symbols are evenly spaced at intervals. In the frame. It should be noted that the value of P can be artificially set. In this case, only the P=2bit indication needs to be used in the control information. As shown in the figure, “01” indicates that the first OFDM symbol does not actually have high priority traffic transmission, and the second OFDM symbol has high priority traffic transmission. The "01" 2 bits directly indicate that the resource is occupied by the high priority service.

As shown in FIG. 11, when a radio frame is composed of 0 TTIs, firstly, each frame has P=2 TTIs, which can be used to transmit high-priority services, and the two TTIs are evenly spaced in the frame. It should be noted that the value of P can be artificially set. In this case, only the P=2bit indication needs to be used in the control information. As shown in the figure, “01” indicates that the first TTI does not actually have high-priority service transmission, and the second TTI has high-priority service transmission. The "01" 2 bits directly indicate that the resource is occupied by the high priority service.

Further, the step 12 in the foregoing embodiment of the present disclosure, after the control information indicating that the resource block is occupied by the high-priority service is sent to the terminal, further includes:

Step 13: If the resource block actually occupied by the high-priority service has resources that are not occupied by the high-priority service, the resource block actually occupied by the high-priority service is sent to the terminal.

Further, in the foregoing embodiment of the present disclosure, if the resource block actually occupied by the high-priority service has resources that are not occupied by the high-priority service, the resource actually occupied by the high-priority service is used. The method of sending a block to the terminal, the step 13 may include:

Step 131: Define a set of L elements for the resource block, where each element corresponds to a local or all resources in the resource block;

In step 132, the m=Log(L) bit is used to dynamically indicate the resources actually occupied by the high priority service.

The method of dynamically indicating the resources actually occupied by the high priority service using the m=Log(L) bit will be described in detail below with reference to two specific embodiments.

First, an OFDM symbol or a subframe indicating a minimum scheduled transmission time interval unit is divided from the frequency domain, and a set of resources is used to represent elements of the set of Φ={R ₀ , R ₁ , . . . R _N-1 } For N, the elements in the set have different resource sizes, and R ₀ contains the smallest resource, and may also be an empty set (indicating that the corresponding OFDM symbol or subframe has no actual transmission), and the resource represented by the set element follows the set. The increase of the element subscript gradually increases, but does not necessarily increase uniformly. For example, R _i+1 includes more resources than R _i , and R _{i+1 may} include R _i or may not be included. R _N-1 contains the largest resources, but also all resources, indicating that all resources are occupied. The specific resource division mode needs to be determined in combination with the high-priority service usage resource, and is sent to the UE through high-level signaling or system broadcast information. For example, when a high-priority service allocates resources, it is preferentially allocated from a low resource block RB index. When dividing a resource set, it may be divided according to RB index, R ₀ corresponds to RB index is less than or equal to x, and R ₁ corresponds to RB index is less than or equal to y, y. More than x, R ₂ corresponds to RB index is less than or equal to z, z is greater than y, and so on. It can be understood by those skilled in the art that the foregoing subframe is merely exemplary, and the disclosure is not limited thereto; in the LTE communication system, the foregoing subframe may be a TTI; in other communication systems different from the LTE communication system Other elements may be used instead of the above-described subframes as long as they can describe a basic scheduling time unit in the time domain.

Alternatively, the value of N depends on the granularity of resources required and the overhead that can be tolerated. For example, if N=2 and the bandwidth is 20MHz and there are 100 RBs, only 1 bit can be indicated, but if R ₀ is 50 RBs and R ₁ is 100 RBs, even if only 1 RB is high priority service. The occupation also needs to indicate that R ₀ and other 49 RBs corresponding to R ₀ cannot be indicated, so that it cannot be used by the LTE user, that is, the granularity is indicated to be coarse, which causes waste of resources.

By using m=log2(N) bits in the common control channel or the UE-specific control channel to dynamically indicate the resources actually occupied by the high-priority service, the user obtains the scheduling information of the UE-specific control channel to obtain the scheduled service. Time-frequency resources, which determine that there are currently scheduled resources OFDM symbols (for intra-frame scheduling) or subframes (for multi-subframe scheduling) where high-priority services are not included; if included, m bits need to be read to determine which resources are actually occupied by high-priority services, and corresponding Data processing.

As shown in FIG. 12, an OFDM symbol is evenly divided into N shares from the frequency domain, R _{0 is} 1/N, and R _{i is} (i+1)/N shares, and R _N-1 takes the entire resource. The i+1 resources included in R _i may be continuous or may be spaced or evenly spaced. If the current indication information indicates R _i , the user understands that the high priority service occupies the resources of R _i , that is, occupies (i+1)/N resources. The drawing from right to left by m = log2 (N) in a first OFDM symbol bit information indicating R _1, then the user is understood to high-priority services occupy resources of R _1, i.e. occupied 2 / N resources; if the current indication information in the fourth OFDM symbol indicates R ₂ , the user understands that the high priority service occupies the resource of R ₂ , that is, occupies 3/N resources.

As shown in FIG. 13, for example, a TTI is uniformly divided into N shares from the frequency domain, R ₀ takes 1/N, and R _i takes (i+1)/N shares, and R _N-1 takes the entire resource. The i+1 resources included in R _i may be continuous or may be spaced or evenly spaced. If the current indication information indicates R _i , the user understands that the high priority service occupies the resources of R _i , that is, occupies (i+1)/N resources. In the figure, from right to left, in the second TTI, R ₀ is indicated by m=log2(N) bit information, and the user understands that the high priority service occupies the resource of R ₀ , that is, 1/N is occupied. parts of resources; and a third TTI by m = log2 (N) bits of information indicating R _3, the user is understood to high-priority services occupy resources R _3, i.e., occupied by 4 / N parts resources.

Further, in the foregoing embodiment of the present disclosure, if the resource block actually occupied by the high-priority service has resources that are not occupied by the high-priority service, the resource block actually occupied by the high-priority service is sent to the terminal. The method of step 13 may further include:

Step 133: Determine whether resource blocks that are scheduled to be allocated to the terminal and are not occupied by the high priority service are available.

Further, in the foregoing embodiment of the present disclosure, a method for determining whether a resource block that is allocated to a resource block of a terminal and is not occupied by a high-priority service is available, the step 133 may include:

Step 1331, indicating, by using 1 bit, whether resource blocks in which all high-priority services within the user resource scheduling range are located are available; or

Step 1332, indicating corresponding to each resource block occupied by the high priority service by Y bit Whether the resource is available, where Y is the number of the resource blocks.

Specifically, the resource blocks described in the above embodiments of the present disclosure include: orthogonal frequency division multiplexing OFDM symbols in a subframe or a transmission time interval TTI in a frame.

A method for determining whether a resource block allocated to a resource block of a terminal and not occupied by a high priority service is available through a terminal-specific control region using a 1-bit or Y-bit is described in detail below in conjunction with two specific embodiments.

As shown in FIG. 14 , when the OFDM symbol of all the high-priority services in the user resource scheduling range is available, the “1” is used, and the other indications are 0. For UE1, not all Alternate resources are available, indicating that the message is "0", and for UE2, two alternative resources are available, indicating that the message is "1."

As shown in FIG. 15, when indicated by the Y bit, it can be indicated whether the corresponding resource in each TTI occupied by the high priority service can be utilized by the UE, and each bit of the Y bits corresponds to one TTI, which is 0. It means that it cannot be used, and it means that it can be utilized by 1. In the case of a sub-frame: for the UE1: the indication message is "01", indicating that the resource corresponding to the first high-priority service is unavailable, the second one is available; for the UE2, the indication message is "11", indicating that the two high-priority Resources corresponding to the level service are available. This method can also be used for the case where the intra-subframe OFDM symbol is occupied.

In the above method of the embodiment of the present disclosure, by designing the control channel indication and transmitting the control information, the network side device and the terminal can agree on the resource usage when the high priority service occupies the resource transmission of the common service, and appropriately modify the data. The processing method prevents user data from being punctured and reduces user performance. On the other hand, when a high-priority service only occupies part of the resource transmission, the reserved resources can also be used by ordinary users, which improves resource utilization.
