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 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: The present disclosure relates to resource indication methods and apparatus. In one example method, a network device configures resource configuration information for a terminal device. The terminal device determines channel state information based on the resource configuration information, and sends the channel state information. The resource configuration information is used to indicate a first reference signal resource set, L second reference signal resource sets, and a type of the first reference signal resource set. The first reference signal resource set includes resources for M first reference signals, and a resource for one of the M first reference signals is used to measure a channel.

Abstract: In a depth estimation method, a depth estimation apparatus obtains a first color image, and inputs the first color image into a first depth estimation model to obtain a first intermediate depth image. The depth estimation apparatus then inputs the first color image and the first intermediate depth image into a second depth estimation model to obtain a first target depth image. The second depth estimation model is obtained through training based on a color image and a target depth image corresponding to the color image, and the first depth estimation model is obtained through training based on the color image and an intermediate depth image corresponding to the color image.

Abstract: This application provides a link failure recovery method and apparatus. A terminal is configured to send first request information to a network device on the same resource (namely, a first resource) when detecting that a link of any one of a plurality of cells fails or the links of more than one of the plurality of cells fail, to notify the network device that a link of at least one of the cells fails. In this way, in a multi-carrier scenario resource overheads are reduced as compared to the solution of using separate resources to notify link failures in multiple cells.

Abstract: This application provides example methods and example devices for sending channel state information. One example method includes receiving L reference signals, where L is a positive integer greater than or equal to 1. Channel state information can then be sent, where the channel state information includes resource indexes of M reference signals in the L reference signals, K pieces of antenna panel state information, and M sets of channel quality information, where the K pieces of antenna panel state information indicate states of antenna panels, the K pieces of antenna panel state information are related to M sets of channel quality information, the M sets of channel quality information are in a one-to-one correspondence with the resource indexes of the M reference signals.

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.

Abstract: Embodiments of the present invention disclose an information transmission method, a related device, and a system. The method includes: determining, by a terminal device at a moment n, that a communication failure occurs on a physical downlink control channel (PDCCH) on a first control resource set; and if the terminal device detects, within a first time period after the moment n, that channel quality of the PDCCH on the first control resource set meets a first preset condition, canceling, by the terminal device, sending of communication failure recovery request information, and/or stopping, by the terminal device, timing of a communication failure recovery clock. In the embodiments of the present invention, a communication link can be rapidly recovered after a communication failure occurs.

Abstract: A communication method and a communications apparatus are provided. The method includes: determining a first bandwidth part (BWP) and a second BWP; determining an association relationship between the first BWP and the second BWP; and recovering a link of a first downlink resource of the first BWP based on the association relationship and/or detecting a link failure of a second downlink resource of the second BWP based on the association relationship. The link of the first downlink resource of the first BWP can be accurately recovered based on the association relationship between the two BWPs, thereby ensuring communication reliability.
