Abstract: A precoding matrix indication method and a related device. In the method, a transmit end can group K combination coefficients based on an amplitude value of each of the K combination coefficients, to obtain Q combination coefficient groups, and determine a phase value of each combination coefficient in each combination coefficient group. The amplitude value of each combination coefficient is determined by using a same amplitude quantization bit quantity and a same amplitude quantization rule. In addition, phase quantization bit quantities and/or phase quantization rules used by at least two of the Q combination coefficient groups are different.

Abstract: Example link recovery methods and apparatus are described. One example method includes determining a link failure of a first control resource set, where the first control resource set is a control resource set configured by a first master information block MIB. A link failure recovery request is sent, where the link failure recovery request is used to request to recover a communication link of the first control resource set. The first control resource set may be a control resource set (CORESET), a control region, or an enhanced physical downlink control channel (ePDCCH) set defined in a 5G mobile communications system.
