Abstract: A communication method and apparatus. The method includes: a terminal device receives a first parameter from a network device, where the first parameter is used to determine indication information of a first precoding matrix and a second parameter, and the second parameter is used to determine indication information of a second precoding matrix; and then, the terminal device sends the indication information of the second precoding matrix to the network device. The method and the apparatus may be used to determine indication information of a precoding matrix when a rank indicator value reported by the terminal device is 3 or 4.

Abstract: An access network device sends first indication information to a terminal device, and sends second indication information to the terminal device. When the second indication information indicates a first value, the first indication information indicates a first port index group in a plurality of port index groups included in a first set. When the second indication information indicates a second value, the first indication information indicates a second port index group in a plurality of port index groups included in a second set. The first port index group and the second port index group have an association relationship.

Abstract: A communication method and a communication apparatus. A terminal device receives first indication information and second indication information from a network device and determines, based on the first indication information and the second indication information, that a first resource in a resource group corresponding to at least one DMRS port in any one of at least one first time unit does not carry a first data signal, and that a second resource in the resource group corresponding to the at least one DMRS port in another time unit in a time unit set other than the at least one first time unit carries the first data signal. The terminal device receives the first data signal from the network device on a third resource in all the time units in the time unit set, where the third resource includes the second resource and does not include the first resource.

Abstract: A signal monitoring method and apparatus are provided. The method includes: determining, by a terminal device based on received configuration information, an index of a first time unit in which a start position of a control channel resource of a control channel is located, where a system frame number in which the first time unit is located is determined based on a first parameter; and monitoring, by the terminal device, the control channel starting from a time domain position corresponding to the index of the first time unit. In this way, the terminal device can monitor the control channel starting from a time unit corresponding to the index of the first time unit, to avoid monitoring the control channel extremely early and reduce overheads.

In the indication information, a first group of indication information includes reference amplitude indication information corresponding to each spatial layer, and differential amplitude indication information and phase indication information of X weighting coefficients, and a second group of indication information includes differential amplitude indication information and phase indication information of Y weighting coefficients. Values of X and Y are related to a first parameter, and a sum of X and Y is equal to KNZ−v. It can be learned that the quantity of weighting coefficients included in each of the first group of indication information and the second group of indication information is determined based on the first parameter.
