Technical Field

Background

The 5G (5 th Generation mobile networks, 5th Generation wireless systems or 5th-Generation, fifth Generation mobile communication technology) NR (New Radio, new air interface) supports Frequency spectrum of different FR (Frequency Range). With the repeated cultivation of the frequency spectrum of the previous generation mobile communication network, the available frequency spectrum of the 5G NR is more dispersed and the bandwidth is narrower for the low-frequency FR1 frequency band. For the FR2 band and some FR1 bands, the available spectrum may be wider, thus requiring multi-carrier operation. While ensuring that these scattered spectrum or wider bandwidth spectrum is utilized in a more spectrally efficient, power efficient and flexible manner, higher throughput and wider coverage may be provided.

The current scheduling mechanism of NR supports a single DCI (Downlink Control Information ) on one cell to schedule a PDSCH (Physical Downlink Shared Channel ) or PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) on one cell. When PDSCH or PUSCH scheduling is performed on a plurality of cells, a plurality of DCI needs to be transmitted for PDSCH or PUSCH scheduled on each cell.

Detailed Description

The technical scheme of the present disclosure is described in further detail below through the accompanying drawings and examples.

In the related art, when the DCI schedules the PDSCH or PUSCH in one cell, the DCI includes frequency domain resource allocation indication information for indicating the frequency domain resource allocation of the PDSCH or PUSCH in one cell. The frequency domain resource allocation has a plurality of types, wherein type 1 allocates consecutive resource blocks within a cell.

For uplink frequency domain resource allocation type 1, DCI adoptsIndividual bits or-> The number of bits indicates the number of allocated starting virtual resource blocks and allocated consecutive virtual resource blocks, or +.>Or (b)The number of bits indicates the number of allocated starting virtual resource block groups and allocated consecutive virtual resource block groups. Wherein (1)>Indicating the initial or active upstream BWP (Bandwidth Part) size, N _{UL_hop} The number of bits representing the frequency offset for indicating PUSCH frequency hopping, represents the starting position of the uplink BWP, i.e. the common resource block index of the starting resource block, K1 represents the granularity of the type 1 uplink frequency domain resource allocation. The resource blocks in the uplink BWP are divided into resource block groups in units of K1. First resource block group sizeIf-> Last resource block group size-> Otherwise, the size of the last resource block group is K1; the remaining resource block group size is K1.

For downlink frequency domain resource allocation type 1, DCI adoptsThe number of bits indicates the number of allocated initial virtual resource blocks and allocated continuous virtual resource blocks, or The number of bits indicates the number of allocated starting virtual resource block groups and allocated consecutive virtual resource block groups. Wherein (1)>Indicating the initial or active downstream BWP size, or the control resource set 0 (Control Resource Set, coreset 0) size, +.> Represents the starting position of the downlink BWP, i.e. the common resource block index of the starting resource block, K2 represents the granularity of the type 1 downlink frequency domain resource allocation. The resource blocks in the downlink BWP are divided into resource block groups in units of K2. First resource block group sizeIf->Last resource block group size- > Otherwise, the size of the last resource block group is K2; the remaining resource block group size is K2.

The inventors found that when PDSCH or PUSCH scheduling is performed on a plurality of cells, the related art needs to transmit a plurality of DCIs, and the DCI overhead is large. If the above number of bits are used for each cell in a single DCI to indicate frequency domain resource allocation, the bit overhead of the frequency domain resource allocation indication information is large.

The present disclosure proposes a joint indication method for multi-cell frequency domain resource allocation by using a single DCI, which reduces bit overhead and improves resource utilization efficiency. It should be noted that, DCI in the present disclosure may also be used to schedule PDSCH or PUSCH of some or all carriers in multiple carriers, and one PDSCH or PUSCH may be scheduled in each carrier, where in this case, cells may be replaced by carriers in the present disclosure, which does not affect application of the scheme, and belongs to the protection scope of the present disclosure. For Uplink transmission of one cell, a SUL (Supplementary Uplink, complementary Uplink) carrier and a NUL (Normal Uplink) carrier may be configured. The DCI may indicate PUSCH of the cell is transmitted on a SUL carrier or a NUL carrier. The DCI may also indicate that PUSCH of the cell is transmitted simultaneously on the SUL carrier and the NUL carrier. The cells in the multi-cell in the present disclosure may also be cell groups, and the frequency domain resource allocation of PDSCH or PUSCH is the same in the cells included in each cell group, and at this time, the cells in the present disclosure may be replaced with cell groups, which does not affect the application of the scheme, and belongs to the protection scope of the present disclosure.

A flow chart of some embodiments of the frequency domain resource allocation indication method of the present disclosure is shown in fig. 1.

In step 120, the network side device determines a frequency domain resource allocation of PDSCH or PUSCH on the plurality of cells. In some embodiments, the frequency domain resource allocation of at least one of PDSCH or PUSCH on each cell may be determined based on any frequency domain resource allocation method in the related art, respectively. In some embodiments, the RIV (Resource Indicator Value ) for each cell may be determined, denoted RIV _i The resource indication value is used to indicate the frequency domain resource allocation of PDSCH or PUSCH on a single cell, where i is the cell identity.

In step 140, the network side device transmits DCI to the terminal. In some embodiments, the network-side device is a base station, or a device in an uplink direction of the base station, and sends DCI to the terminal through the base station. The DCI includes multi-cell frequency-domain resource allocation indication information indicating frequency-domain resource allocation of PDSCH or PUSCH on a plurality of cells. In some embodiments, the plurality of cells is greater than 2 cells. In some embodiments, the plurality of cells may also be 2 cells.

In some embodiments, the multi-cell frequency domain resource allocation indication information may be generated in conjunction with frequency domain resource allocation of a plurality of cells. In some embodiments, each bit of the multi-cell frequency domain resource allocation indication information is used to indicate the frequency domain resource allocation of PDSCH or PUSCH on multiple cells. That is, different values of bits of the multi-cell frequency domain resource allocation indication information are adopted to indicate different situations of frequency domain resource allocation of PDSCH or PUSCH on a plurality of cells. Therefore, a single DCI can indicate the frequency domain resource allocation condition of multiple cells, and the bit overhead of the DCI is reduced.

In some embodiments, the RIV may be indicated according to the resources of each cell _i And determining a joint resource indicated value RIV, wherein the joint resource indicated value has a corresponding relation with the resource indicated value of each cell, and the multi-cell frequency domain resource allocation indication information is used for representing the joint resource indicated value. For example, decimal joint resource indication values are determined, and multi-cell frequency domain resource allocation indication information is generated according to the joint resource indication values, and in some embodiments, the generation mode includes binary conversion.

Further, the DCI issued in one cell carries the multi-cell frequency domain resource allocation indication information. The DCI is carried through a PDCCH (Physical Downlink Control Channel ) on one cell. In some embodiments, as shown in fig. 2, unlike the related art manner shown in the upper half of the figure, there is no need to issue control channels carrying frequency domain resource allocation indication information for the frequency domain resource allocation of the data channel on each cell (the control channels 211 to 231 occupy the resource issue frequency domain resource allocation indication information in the cells 1 to 3, respectively, the control channel overhead is large, resulting in a reduction of the total amount of resources that can be utilized by the data channels 212 to 232), but the frequency domain resource allocation indication information of a plurality of cells is carried and issued through the control channel on a single cell as shown in the lower half, the control channel 241 issues the frequency domain resource allocation indication information for a plurality of cells only through the cell 1, the overhead is small, and thus the total amount of resources that can be utilized by the data channels 242 to 244 increases.

Based on the method in the above embodiment, unified scheduling between cells can be realized, that is, PDSCH or PUSCH on multiple cells are scheduled by DCI on one cell, so that compared with the case that multiple scheduling DCIs are respectively transmitted for data channels on each cell, the method has the advantages of reducing the overhead of a control channel, reducing the collision probability of the control channel, improving the throughput, reducing the power consumption of UE and the like, and effectively improving the spectrum efficiency and the power efficiency of discrete spectrum or wider bandwidth spectrum.

In some embodiments, the joint indication of the multi-cell frequency domain resource allocation may use different values of bits of the multi-cell frequency domain resource allocation indication information to indicate different situations of the multi-cell frequency domain resource allocation, where each value indicates one situation of the multi-cell frequency domain resource allocation, so that a bit length of the multi-cell frequency domain resource allocation indication information is less than or equal to a sum of bit lengths corresponding to each of the plurality of cells, where the bit length corresponding to a cell is a bit length required to carry information indicating the frequency domain resource allocation of the PDSCH or PUSCH on the corresponding cell. In some embodiments, the continuous value of the bits of the multi-cell frequency domain resource allocation indication information may be used to indicate different frequency domain resource allocations of PDSCH or PUSCH on the multiple cells, so as to compress the bit length required by the multi-cell frequency domain resource indication information, and further reduce the bit overhead.

In some embodiments, a weighted sum of the resource indicator values for each cell may be used as the joint resource indicator value. For example, when i=1, the weight of the resource instruction value of the i-th cell (i.e., 1-th cell) is set to 1; when i is a positive integer greater than 1, the weight of the resource indication value of the i-th cell is set to be the product of the first parameters of each of the 1 st cell to the i-1 th cell, where the first parameters are the sum of the positive integer series with the second parameters as the maximum value, and the second parameters refer to parameters related to the BWP size of the cell.

In some embodiments, in the case of frequency domain resource allocation of PUSCH, the second parameter is an initial or active uplink BWP size. In some embodiments, in the case of frequency domain resource allocation of PDSCH, the second parameter is an initial or active downlink BWP size, or a control resource set CORESET 0 size.

In some embodiments, the ith cell is a cell sequence number of the cells after the cells are sequenced according to an ascending or descending order of cell indexes, i is greater than or equal to 1 and less than or equal to M, and M is the number of the cells, so that both parties of communication can conveniently agree on cell sequences, and accuracy of information analysis is improved. In some embodiments, the cell index is a serving cell index, and may also be other cell indexes configured for higher layer signaling.

In some embodiments, the bit length of the multi-cell frequency domain resource allocation indication information is the length of the binary number of the product of the first parameters of each cell, so that compared with directly splicing the frequency domain resource allocation indication information of each cell, the required bit cost can be reduced, and the utilization efficiency of resources can be improved.

In some embodiments, the resource indication value RIV of the current cell i is determined according to the number of the initial virtual resource blocks and the continuous virtual resource blocks of the PDSCH or the PUSCH allocated in the current cell _i The joint resource indication value RIV is:

By such a method, the bit length required for representing the joint resource indication value RIV can be made smaller than that required for representing eachRIV (RIV) _i The sum of the required bit lengths of the multi-cell frequency domain resource allocation indication information is reduced, and the purpose of improving the utilization efficiency of resources is achieved.

In some embodiments, based on the method in equation (1), the RIV of each cell is represented by the multi-cell frequency domain resource allocation indication information _i Initial virtual Resource Block (RB) allocated by each cell _start，ci Number L of allocated continuous virtual resource blocks _RBs，ci As shown in fig. 3A, it can be seen that by such a method, the bit overhead required for the multi-cell frequency domain resource allocation indication information and the number of resources occupied by the corresponding DCI can be reduced, thereby improving the resource utilization efficiency.

In some embodiments, in the case of frequency domain resource allocation of PUSCH, the second parameter is: the remainder of the starting position of the upstream BWP divided by the granularity of the type 1 upstream frequency domain resource allocation is rounded up with the quotient of the upstream BWP size and the granularity of the upstream frequency domain resource allocation. In some embodiments, the second parameter N is in the case of frequency domain resource allocation of PUSCH _{RBG，K1，ci} Can be expressed as:

where mod is the operator of the modulo (i.e., the remainder) operation,for the i-th cell uplink BWP size,for the starting position of the i-th cell uplink BWP, K1 is the granularity of the type 1 uplink frequency domain resource allocation, +.>An operator rounded up.

In some embodiments, in case of frequency domain resource allocation of PDSCHThe second parameters are: the remainder of the division of the starting position of the downlink BWP by the granularity of the type 1 downlink frequency domain resource allocation is rounded up with the sum of the downlink BWP size and the quotient of the granularity of the downlink frequency domain resource allocation. In some embodiments, in the case of frequency domain resource allocation of PDSCH, the second parameter is N _{RBG，K2，ci} Can be expressed as:

wherein mod is an operator of the modulo operation,for the i-th cell downlink BWP size,for the starting position of the i-th cell downlink BWP, K2 is the granularity of the type 1 downlink frequency domain resource allocation.
