摘要： This application provides a reference signal transmission method, including: determining at least two first reference signal resources; receiving a first channel based on the at least two first reference signal resources when a scheduling offset is less than or equal to a preset threshold and/or there is no spatial relation parameter information indication field in downlink control information DCI; and demodulating the first channel. When data on at least two reference signal resources needs to be received within a period of time, the method can increase a probability that a terminal device successfully receives the data.a

摘要： An information transmission method, an apparatus, and a device are disclosed. The method includes: A terminal receives first signaling, where the first signaling includes a first field, a state value of the first field is used to indicate a first spatial relation parameter for receiving a first channel, the state value of the first field is one of a plurality of candidate state values corresponding to the first field, and at least one of the plurality of candidate state values corresponds to two or more spatial relation parameters. The terminal obtains one or more target spatial relation parameters in the first spatial relation parameter, and receives the first channel based on the one or more target spatial relation parameters. In this method, the terminal receives the first channel by receiving the first signaling sent by a base station and obtaining a target spatial relation parameter in a plurality of spatial relation parameters, to cope with an issue of indicating QCL information in a scenario in which one piece of data is scheduled by each of a plurality of pieces of DCI signaling and the data comes from different TRPs.

摘要： Embodiments of this application provide a link failure recovery method and a related device. In the link failure recovery method, a terminal device may send first indication information on a first uplink resource based on information about a spatial relation parameter, to indicate that a link failure occurs in a i th cell in N second cells. Correspondingly, a network device may receive the first indication information on the first uplink resource based on the information about the spatial relation parameter, and send link failure recovery response information based on the first indication information, to recover a failed link. The information about the spatial relation parameter is information about a spatial relation parameter used to send a channel and/or a signal of a first cell, and the first uplink resource is an uplink resource of the first cell. Therefore, the network device does not need to configure a plurality of uplink resources that are associated with a plurality of reference signal resources of a second cell and that are used to indicate that a link failure occurs in the second cell, thereby reducing resource overheads.

摘要： This application provides a channel state information transmission method and an apparatus. The method includes: receiving, by a terminal, N reference signal groups, where each of the N reference signal groups includes at least two reference signals that are simultaneously received; and sending indication information used to indicate channel state information of at least one reference signal in each of K reference signal groups. Therefore, the terminal can feed back the channel state information of the reference signal in a scenario in which a plurality of reference signals can be simultaneously received, so that a network device selects a beam from a plurality of beams that can be simultaneously sent to send data. In this way, when a quantity of selected beams is greater than 1, communication efficiency is improved; when a beam with high communication quality is selected from the plurality of beams, communication quality can be improved; and when the channel state information of the at least one reference signal is fed back, if a quantity of the at least one reference signal is less than a total quantity of corresponding reference signal groups, signaling overheads can be reduced.
