Abstract: A channel quality information transmission method and system are described. A terminal device determines a reporting priority of channel quality information according to a reporting priority rule when reporting of first channel quality information conflicts with reporting of second channel quality information. The device further determines to-be-reported content or to-be-discarded content based on the reporting priority of the channel quality information. The terminal device reports the to-be-reported content to a network device.

Abstract: The present disclosure provide a method and an apparatus for transmitting channel state information. A terminal device receives a reference signal from a network device, obtains a precoding matrix based on the reference signal. The terminal device determines first amplitude information and second amplitude information of the precoding matrix. The first amplitude information is used to indicate amplitude quantization information of a wideband, and the second amplitude information is used to indicate amplitude quantization information of N subbands of the wideband. The terminal device sends the first amplitude information and the second amplitude information to the network device.

Abstract: This application provides example reference signal (RS) transmission methods and example communication apparatuses. One example reference signal transmission method includes receiving, by a terminal device, first information in a first time unit, where the first information triggers the terminal device to transmit a RS. The terminal device can then transmit the RS in a second time unit, where the second time unit is indicated by a time offset indicator n in valid uplink transmission time units starting from the first time unit.

Abstract: This application provides example antenna panel status indication methods and apparatuses. One example method includes sending first antenna panel status information, where the first antenna panel status information indicates a status of at least one antenna panel. Response information of the first antenna panel status information can then be received. It can then be determined, based on the response information, that the status of the at least one antenna panel takes effect.

Abstract: This application provides a communication method and a communications apparatus. The method includes: determining first antenna panel information; sending a link failure recovery request message, where the link failure recovery request message indicates the first antenna panel information; and sending an uplink signal based on the first antenna panel information. When a link between a terminal device and a network device fails, and the terminal device requests the network device to recover the link, in the method, information about an antenna panel for sending an uplink signal is indicated by using a link failure recovery request message. For example, the terminal device may indicate, in an explicit or implicit manner, the information (a panel ID) about the antenna panel.

Abstract: This application provides a link failure recovery method and apparatus. When a link failure occurs and link recovery is performed, if a terminal device determines that no new link is identified, according to the method, the terminal device may report, to a network device, an identifier of a cell in which the link failure occurs and information indicating whether a new link is identified for each cell. The network device may reconfigure a new resource set based on the information, and notify the terminal device of the new resource set by using downlink control information DCI. In other words, a reference signal in another resource set is triggered by using the DCI, and the reference signal in the resource set is reported for link recovery.

Abstract: In the 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 ith cell in N second cells. 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.

Abstract: This application provides a method which 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.
