    Abstract: Disclosed are a method for processing multi-transmission reception point (TRP) data, a base station, a terminal, and a storage medium, used for solving the problem in the prior art of low reliability of data transmission when data is transmitted by using multiple TRPs. The method includes a base station generates a resource allocation instruction and a quasi-co-location (QCL) instruction according to the mapping relations between a transmission coding block of data to be transmitted and multiple TRPs, and the QCL instruction is used for indicating the associations between an allocated resource and the QCL identifiers of the multiple TRPs, and the allocated resource comprises a time-frequency resource or a demodulation reference signal (DMRS) port resource; and sends downlink control information (DCI) to a user terminal, the DCI comprising at least the resource allocation instruction and the QCL instruction as well as a data merging and detection instruction.

    Abstract: A TA configuration method, a terminal and a network side device are provided. The TA configuration method includes: transmitting, by a terminal, a first SRS to a network side device on N SRS resource sets through N antenna groups respectively, N being an integer greater than 1; and receiving, by the terminal, a first configuration message transmitted by the network side device, the first configuration message being used to configure N TAs, the N TAs corresponding to the N antenna groups respectively, the N TAs being obtained by the network side device through measuring the first SRS on the N SRS resource sets.

    Abstract: Disclosed in the present application are methods for sending and receiving channel state information (CSI), a terminal device and a network device, which are used to provide a CSI sending method or receiving method on the basis of a Rel-16 codebook structure. The method for sending CSI includes determining a compressed basis vector in a precoding matrix, the compressed basis vector belonging to a set of candidate basis vectors, and the compressed basis vector weighted by coefficients of the precoding matrix is used to construct frequency domain characteristics of the precoding matrix; and sending the CSI to a network device, and the CSI includes basis vector indication information, and the basis vector indication information is used to indicate the compressed basis vector.

    Abstract: The present application can provide an uplink transmission method and apparatus. The method comprises: a base station instructs a UE to send SRSs corresponding to N groups of SRS resources, each of the N groups of SRS resources comprising one or more SRS resources; N being a positive integer; the base station receives the SRSs sent by the UE to determine X groups of uplink scheduling information, each of the X groups of uplink scheduling information corresponding to one group of SRS resources in the N groups of SRS resources; uplink scheduling information in different groups corresponding to SRS resources in different groups; X being a positive integer greater than one and not greater than N; the base station sends the determined X groups of uplink scheduling information to the UE so that the UE transmits an uplink signal according to the X groups of uplink scheduling information.
