    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.

    Abstract: Provided are a beam management method and apparatus, and a network side device, a terminal and a storage medium. The method includes receiving beam information for beam management sent by a terminal, wherein the beam information comprises uplink beam information or downlink beam information; determining specified information for beam management according to the beam information, wherein the specified information comprises terminal location information and/or beam quality information; and determining transmission beams for signal transmission and/or a trend of transmission beam change according to the specified information and network deployment information, wherein the signal transmission comprises uplink signal transmission or downlink signal transmission. The great overhead and delay problems caused by the frequent beam sweeping process in high-speed occasions can be solved, the beam management strategy can be optimized and beam sweeping time and beam overhead can be saved.

    Abstract: The present application provides an information transmission method and apparatus, and a storage medium. The method includes: determining whether at least one sounding reference signal (SRS) resource is used for multiple usages; determining, according to a first result, a bit width and/or a coding mode of SRS resource indicator (SRI), where the SRI is used to indicate an SRS resource corresponding to transmission of a physical uplink shared channel (PUSCH); the first result is that the at least one SRS resource is used for multiple usages, or, no SRS resource is used for multiple usages. Therefore, when transmitting an SRS of the SRS resource set, the terminal will perform the SRS transmission according to requirements of multiple usages, so the network device can use the same SRS resource set to realize the measurement of multiple usages, thus improving resource utilization and reducing resource waste.
