Description

Resource allocation method and device for physical uplink control channel
Technical Field
The present application relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for resource configuration of a Physical Uplink Control Channel (PUCCH).
Background
In a satellite communication system, Uplink Control Information (Uplink Control Information) may be transmitted along PUCCH format 1(format 1) and PUCCH format 3 of a New Radio (NR) system. PUCCH format 1 is used to carry 1-to-2-bit Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) transmission or carry uplink Scheduling Request (SR) transmission, spread with orthogonal sequences in the time domain, perform cyclic shift based on ZC (Zadoff-chu) sequences in the frequency domain, and implement large multiuser multiplexing transmission capacity through dual spreading in the time domain and the frequency domain. The initial cyclic shift parameters of the cyclic shift of the ZC sequence are configured through signaling, so as to ensure that different user equipments (ues) working in the same Resource Block (RB) realize orthogonal transmission of data through different cyclic shifts in the frequency domain when the time domain locations are the same and the same orthogonal sequence is used, thereby realizing multiplexing transmission of different users on the same time-frequency domain Resource.
In the NR system, before a PUCCH Resource is configured without a dedicated Radio Resource Control (RRC) (i.e., in an initial access procedure, an RRC reestablishment procedure, or the like), the PUCCH Resource is notified by system information. Specifically, the 4-bit Information in the Remaining System Information (RMSI) (e.g. System Information Block 1, SIB1) may indicate one set of Information in a predefined table containing 16 sets of Information to the ue for determining the common PUCCH resource set in the cell. And the user equipment determines the proper PUCCH resources to carry out HARQ-ACK transmission in the common PUCCH resource set according to the respective scheduling conditions.
In a satellite communication system, the radius of a cell is large (the diameter can reach more than 1000 km), and the difference of transmission delay from user equipment located at different positions of the cell to a cell base station is large, so that the time when a plurality of users in the cell reach the cell base station cannot be strictly ensured to be completely aligned. In addition, when the radius of the cell is larger, the difference of the multipath propagation delay is also larger. To avoid interference of a signal of one user equipment with a signal of another user equipment, a large cyclic shift is required to ensure orthogonality between ZC sequences. On the other hand, since the resource overhead of the PUCCH in the system needs to be considered, the cyclic shift interval cannot be increased at once. In addition, although the channel difference on different frequency domain resources in the satellite communication cell is not large, the adjacent cell interference situations on different frequency domain resources may be different, and therefore, a more flexible adjustment of RB offset dedicated to the cell than that in the NR system is required to implement the division of the common PUCCH resource in the cell to a suitable position on the frequency domain, so as to improve the transmission performance of the PUCCH.
At present, in a satellite communication system, there is no clear method for how to acquire a PUCCH resource common to cells before there is no dedicated RRC configured PUCCH resource.

Specifically, the base station selects one group from N predefined groups of PUCCH parameters, and sends the configuration index corresponding to the group of PUCCH parameters to all user equipment in the cell by carrying the configuration index in the configuration information.
Wherein the length of the configuration information is not more than 4 bits. The configuration information is carried in the system information, and the system information is SIB1 or RMSI.

In other embodiments, when the determined set of PUCCH parameters includes PUCCH symbols, PRB offset, and initial cyclic shift index set, the base station determines a PUCCH resource set according to the PUCCH symbol number, PRB offset, and initial cyclic shift index set.
Further, the base station determines a PUCCH resource set according to the determined set of PUCCH parameters, further including: determining a starting position of a PUCCH as a specific symbol in one slot, for example, the specific symbol is a first symbol; determining the format of the PUCCH as a predefined PUCCH format, such as PUCCH format 0 or PUCCH format 1 in a satellite communication system; it is determined whether the PUCCH uses frequency hopping or does not use frequency hopping.
The following describes the flow shown in fig. 1 and 2 in detail by taking as an example that the system defines 16 sets of PUCCH parameters in advance as shown in table 1, the SIB1 defines 4-bit information for indicating the configuration index of the 16 sets of PUCCH parameters, the configuration index and the predefined 16 sets of PUCCH parameters are shown in table 7, the pre-agreed initial cyclic shift index set is {0,6}, and the base station selects and uses a set of PUCCH parameters corresponding to the configuration index of 0 to determine the set of common PUCCH resources in the cell.
Based on the parameters predefined by the system, the base station generates SIB1 information, sets 4-bit information in the SIB1 for indicating the configuration index of the PUCCH parameter to a state indicating 0, and transmits the SIB1 information in the cell.
All user equipments in the cell receive the SIB1 information to obtain 4-bit information indicating a configuration index of a PUCCH parameter, determine, according to the 4-bit information, a set of PUCCH parameters corresponding to a configuration index of 0, that is, the number of PUCCH symbols is 8, and a PRB offset is 0, thereby determining that the transmission length of the PUCCH in the cell is 8 symbols, and determine 16 common PUCCH resources in the cell by setting RB offset to 0 and a pre-agreed initial cyclic shift index set {0,6} to form a common PUCCH resource set of the cell.
The 16 common PUCCH resources in this cell are shown in table 8, where a hopping direction of 0 indicates: the first hop part (hop) of the PUCCH in-slot hopping transmission is in a low frequency band, and the second hop is in a high frequency band of the BWP which is centrosymmetric; a hopping direction of 1 means: the first hop of the PUCCH for intra-slot frequency hopping transmission is in the high band and the second hop is in the low band of the BWP, which is centrosymmetric.
Specifically, the 16 common PUCCH resources are determined as follows: when the frequency hopping direction is 0, corresponding to 8 common PUCCH resources, and according to the PRB offset which is exclusive to the cell and is 0, determining that starting from the first RB of the BWP of the cell, each RB comprises 2 common PUCCH resources, and corresponding to the initial cyclic shift indexes of 0 and 6 respectively, namely RB #0 comprises 2 common PUCCH resources, RB #1 comprises 2 common PUCCH resources, RB #2 comprises 2 common PUCCH resources, and RB #3 comprises 2 common PUCCH resources; based on the center symmetry of the BWP, when the frequency hopping direction is 1, 8 common PUCCH resources are also associated, and 2 common PUCCH resources, namely RB # x, RB # (x-1), RB # (x-2), and RB # (x-3), each of which is the maximum RB number of the BWP of the cell, exist in 4 RBs starting from the highest RB number of the BWP to the lower band.
And determining 16 common PUCCH resources as a common PUCCH resource set in the cell, wherein each user equipment can determine to use one PUCCH resource for HARQ-ACK transmission according to the downlink scheduling of the user equipment and PUCCH resource indication information corresponding to the downlink scheduling.
