Description

[Technical field]

[0001] The present application relates to the technical field of communications, and in particular to a port mapping method and terminal for a sounding reference signal. [Background technology]

[0002] In the NR system, a sounding reference signal (SRS) can be used for beam management, codebook-based transmission, non-codebook-based transmission, and antenna switching transmission. A terminal can obtain multiple SRS resource sets through higher layer signaling, and each SRS resource set configuration includes its purpose, periodicity characteristics, and other configurations.

[0003] In Release-15 / 16, the SRS resource can occupy the last 6 symbols in one slot, and the SRS can be transmitted occupying 1 / 2 / 4 symbols by higher layer signaling, and can be arranged to support comb-2 and comb-4 structures in the frequency domain. Release-17 is an enhancement based on Release-15 / 16, allowing the symbol start position of the SRS resource to be at any symbol within one slot. It also supports the comb-8 structure.

[0004] In the conventional NR protocol, only SRSs with port numbers of 1, 2, and 4 are supported. In order to further improve the performance of uplink transmission, it is necessary to introduce an SRS that supports a larger number of ports, for example, an SRS with 6 or 8 SRS ports. Since it is necessary to ensure orthogonality between different SRS ports as much as possible, the conventional SRS port mapping method cannot be fully applied to the scenarios where the SRS port numbers are 6 and 8.

When the number of ports is 6 and the size of the comb configuration is 8, the 6 ports of the first SRS are divided into two groups, and the ports in the same group adopt the same CS, and the ports in different groups adopt different CS; The CS of the sequence to which each port of the first SRS is mapped is calculated by the following formula: Where: is the CS corresponding to port i, is the cyclic shift offset, is the maximum cyclic shift offset, is the port number, is the number of ports, is the first parameter, is a value specified by default by the network side device and the terminal, and / or a value indicated by the network side device, and / or a value notified by the terminal, The method for port mapping of a sounding reference signal according to claim 2, wherein:

41. The six ports of the first SRS are divided into three groups, and the ports in the same group are mapped to the same comb position, and the ports in different groups are mapped to different comb positions; The comb position to which each port of the first SRS is mapped is calculated by the following formula: Or, Where: is the comb position to which port i is mapped, is the comb offset, is the size of the comb configuration, is a value specified by the network side device and the terminal as a default, and / or is a value instructed by the network side device, and / or is a value notified by the terminal, is a value specified by the network side device and the terminal as a default, and / or is a value instructed by the network side device, and / or is a value notified by the terminal, The port mapping method for a sounding reference signal according to claim 40, wherein: is a value specified by the network side device and the terminal as a default, and / or is a value indicated by the network side device, and / or is a value notified by the terminal.

42. When the number of ports of a first sounding reference signal (SRS) is 6 or 8, the terminal is provided with a first determination unit used to determine a cyclic shift (CS) corresponding to each port of the first SRS and / or a comb position to which each port of the first SRS is mapped; A port mapping device for a sounding reference signal, wherein the size of the comb configuration of the first SRS is N, where N is 2, 4, 6 or 8.

43. A terminal comprising a processor and a memory for storing programs or commands executable by the processor, the programs or commands being executed by the processor to implement the steps of a sounding reference signal port mapping method according to any one of claims 1 to 41.

44. A readable storage medium storing a program or command, which, when executed by a processor, implements the method for port mapping of a sounding reference signal according to any one of claims 1 to 41.
