    Abstract: Disclosed in the present application is a beam failure recovery method and apparatus, a UE, a base station, and a readable storage medium. The method comprises: a UE determines a target reporting mode for beam failure of a first SCell; if the UE detects that beam failure occurs to the first SCell, the UE reports information of beam failure recovery to a base station by using the target reporting mode; the base station performs beam failure recovery of the first SCell according to the detected information indicating that a beam failure event occurs to the first SCell and/or candidate beam information. According to the present application, a UE may perform beam failure reporting of a SCell in a relatively reliable mode or a relatively reliable mode selected by a base station, so that the system is able to use a reliable beam reporting mode of the SCell to perform beam failure recovery of the SCell.

    Abstract: The present invention provides an uplink transmission method and apparatus, for use in improving the flexibility of uplink scheduling. 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 signal transmission method and apparatus, and a storage medium. The method comprises: determining a first determination mode and/or a second determination mode, wherein the first determination mode is a mode for determining first SRS transmission corresponding to an uplink signal, and the second determination method is a mode for determining a first antenna port corresponding to the uplink signal; and transmitting the first determination mode and/or the second determination mode to a UE, and the UE determines the first SRS transmission according to the first determination mode, and/or determines the first antenna port according to the second determination mode, and transmits the uplink signal according to the first SRS transmission and/or the first antenna port. Therefore, the present application can solve the defects in the prior art of a transmission scheme being inflexible and configuration and trigger flexibility of an SRS resource being low due to there being only one antenna port and/or SRS transmission scheme for an uplink signal, thereby reducing the degree of network congestion, and improving the flexibility of signal transmission.

    Abstract: The embodiments of the present application relate to the technical field of wireless communication, and provide a signal transmission method and device, which are used to more flexibly indicate the transmission of information when PUSCH uplink transmission is performed. The method comprises: a network side device first determines transmission information that is used for uplink signal transmission and that corresponds to first resource information, then generates transmission indication information according to the transmission information, and finally indicates the transmission indication information to a terminal so that the terminal determines, according to the transmission indication information, transmission information corresponding to an uplink signal on a frequency domain resource, and transmits the uplink signal according to the transmission information. Since there is a correspondence between the transmission information and the first resource information, the transmission information can be determined according to the first resource information, thus the transmission information can be indicated more flexibly.
