Abstract: Embodiments of the present invention disclose a communication method and a device. Configuration information indicating one or more spatial domain beam basis vector groups and Q thresholds is received from a network device, where the Q thresholds correspond one-to-one to spatial domain beam basis vectors in the one or more spatial domain beam basis vector groups. L spatial domain beam basis vectors are selected from a spatial domain beam basis vector group set. K frequency domain basis vectors are selected from a frequency domain basis vector set for each of the L spatial domain beam basis vectors.

Abstract: Example communication methods and apparatus are described. One example method includes receiving a reference signal from a network device by a terminal device. The reference signal has an association relationship with a weight matrix and a channel between the network device and the terminal device, a quantity of rows or columns of the weight matrix is N, and N is a positive integer less than or equal to a quantity of receive ports of the terminal device. The terminal device determines an estimation result of the weight matrix based on the reference signal, where the estimation result of the weight matrix is used by the terminal device to perform signal detection on a data signal received by the terminal device from the network device, or is used by the terminal device to precode a data signal sent by the terminal device to the network device.

Abstract: This application provides a link failure recovery method and apparatus. A terminal may send first request information to a network device on a same resource (namely, a first resource) when detecting that a link of any one of a plurality of cells fails or links of any more than one of the plurality of cells fail, to notify the network device that a link of at least one of the L cells fails. In this way, in a multi-carrier scenario, compared with resource overheads in a solution in which when a link of each cell fails, one resource is occupied to send one piece of request information, resource overheads are reduced in embodiments of this application.
