Abstract: A signal sending method and a related apparatus are disclosed. In the signal sending method, an access network device obtains a channel information sample, determines M′ frequency domain units in M frequency domain units in an (x+T)th time unit based on the channel information sample, and sends one or more measurement pilots to a terminal in the M′ frequency domain units. The one or more measurement pilots are used to measure CSI, and the channel information sample includes channel information in an xth time unit to an (x+T−1)th time unit, where M′

Abstract: This application provides a reference signal transmission method and an apparatus, used in a multipoint coordination transmission scenario. In one example method, a frequency domain resource that carries a target reference signal in a frequency domain resource or a time domain resource that is associated with each QCL assumption may be separately determined, and then the target reference signal carried on the frequency domain resource that is associated with the QCL assumption is separately received by using the corresponding QCL assumption.

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 disclosure provides example wireless communication methods and communication apparatuses. One example method includes that a network device sends indication information of m first symbol groups used for repeated transmission of a first transport block (TB) to a terminal. The terminal and the network device determine, according to a same rule, a quasi co-location (QCL) assumption corresponding to each of second symbol groups actually used when the first TB is sent or received.

Abstract: Example signal sending methods and apparatus are described. One example method includes obtaining a first insertion loss corresponding to a first resource and a second insertion loss corresponding to a second resource, where the first insertion loss is different from the second insertion loss. A first transmit power corresponding to the first resource is determined based on the first insertion loss. A second transmit power corresponding to the second resource is determined based on the second insertion loss. A first signal is sent on the first resource based on the first transmit power. A second signal is sent on the second resource based on the second transmit power.

Abstract: The present disclosure relates to resource determining methods and apparatus. One example method includes receiving, by a terminal, N pieces of channel measurement reference signal configuration information, where each of the N pieces of channel measurement reference signal configuration information is used to indicate a time domain resource occupied by a channel measurement reference signal on one carrier, serving cell, or bandwidth part, and N is a positive integer, and determining, by the terminal based on the N pieces of channel measurement reference signal configuration information, an orthogonal frequency division multiplexing (OFDM) symbol occupied by a demodulation reference signal (DMRS) in a first time unit.

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: This application provides a communications method and apparatus, to improve uplink transmission performance. The method includes determining, by a terminal device, capability indication information and sending the capability indication information to a network device. The capability indication information is used to determine a power scaling factor, the power scaling factor is a ratio of a sum of actual transmit power of n non-zero antenna ports to channel transmit power, and a maximum value of the channel transmit power is a rated maximum transmit power of a system.
