Abstract: In a method, a terminal device reports, to a network device, a full-power transmission codebook subset corresponding to a frequency band supported by the terminal device before transmission channel switching. The network device or the terminal device in a communications system may determine, according to a specified rule and full-power transmission codebook subsets corresponding to a plurality of source frequency bands, a full-power transmission codebook subset corresponding to a target frequency band after transmission channel switching. The plurality of source frequency bands are frequency bands in which a plurality of target antenna ports are located before antenna port switching, and the plurality of target antenna ports are antenna ports in the target frequency band after antenna port switching.

Abstract: A resource selection method includes: A first terminal device determines an initial candidate resource set including M resources, and determines, based on an RSRP and a collision index that are associated with SCI received in a sensing window, whether to exclude an ith resource in the M resources from the initial candidate resource set, to obtain a candidate available resource set. The collision index is an index of a collision between a reserved resource indicated by the SCI received in the sensing window and an ith periodic resource. The ith periodic resource includes the ith resource and a resource obtained after the ith resource is extended based on a preset first period. Herein, M is a positive integer, and i is a positive integer from 1 to M.

Abstract: A first device sends first control information and second control information to a second device. At least one of a first field or a second field in the first control information indicates a format of the first control information and a format of the second control information. A first format of the first control information indicates a time-frequency resource for feeding back a specified message by the second device. A third format of the second control information indicates a redundancy version of the specified message fed back by the second device. When the first control information is in the first format and the second control information is in the third format, the first device receives, on the time-frequency resource, the specified message fed back by the second device.

Abstract: A resource processing method includes a first device receiving first sidelink control information (SCI) having first indication information. The first indication information indicates a first time-frequency resource, and the first indication information further indicates the first device to send second SCI. The first device sends the second SCI. The second SCI includes second indication information indicating a second time-frequency resource. The first time-frequency resource is a time-frequency resource reserved for a second device to send data to the first device or a time-frequency resource that is reserved for the second device to send data to the first device and that is reserved for the first device to receive data. The second time-frequency resource is a time-frequency resource reserved for the first device to receive data.

Abstract: An interference power measurement method and a device are provided. The method includes: receiving, by a terminal, first signaling that carries first indication information, where the first indication information is used to indicate n first channel state information-reference signal CSI RS resources, and a jth first CSI RS resource is associated with a power parameter Pc,j; and sending, by the terminal, a channel quality indicator CQI, where the CQI is determined based on a total interference power. The total interference power is a linear weighting result of an interference power measured on each of the n first CSI RS resources and an interference power I0 measured on a zero power CSI RS resource. A weighting coefficient of an interference power Ij measured on the jth first CSI RS resource is a function of the power parameter Pc,j, and a weighting coefficient of I0 is a function of 1 - ∑ j = 1 n P c , j .

Abstract: This application provides a method for determining a precoding matrix set, so as to avoid a case in which a relatively large quantity of precoding matrices in a precoding matrix set cannot be used, thereby improving system performance. A terminal device receives indication information from a network device, and determines a second precoding matrix set from a first precoding matrix set whose rank is R based on the indication information. Each precoding matrix W in the first precoding matrix set satisfies W=W1×W2, the second precoding matrix set is a proper subset of the first precoding matrix set, and the second precoding matrix set does not include W=W1×W2 that satisfies the specific condition in the first precoding matrix set.
