Abstract: This application relates to channel state information (CSI) feedback methods and devices. One method comprises: receiving, by a terminal device from a network device, indication information of a channel state information (CSI) reporting band; determining, by the terminal device, based on the indication information, a subset of subbands in a bandwidth part configured for the terminal device for CSI reporting; determining, by the terminal device, CSI reporting priorities of the subset of the subbands based on index numbers of the subset of the subbands, wherein the index numbers of the subset of the subbands are numbered in an ascending numerical order; and sending, by the terminal device to the network device, CSI of M subbands with higher CSI reporting priorities in the subset of the subbands compared to a remainder of subbands in the subset of subbands.

Abstract: This application relates to the field of communication technologies, and provides a reference signal resource determining method and an apparatus. In a multi-point transmission mode, uplink sending occurs between reference signals from different transmission points in a CSI measurement process; consequently, phases are discontinuous on the reference signals received by a terminal device from the different transmission points. First, configuration information of a reference signal resource set is obtained to determine K reference signal resources, where K is a positive integer, and slots in which at least two of the K reference signal resources are located are different slots, or there is an uplink symbol in a first interval of at least two of the K reference signal resources.

Abstract: Embodiments of this application provide a reference signal (RS) sending method and a communication apparatus, which may be applied to a scenario in which an RS is sent based on aperiodic time-domain behavior. The method may include: A terminal device obtains downlink control information (DCI); determines first time information based on the DCI; determines, based on the first time information and a time unit in which the DCI is located, a time unit for sending an RS; and sends the RS in the determined time unit for sending the RS. Correspondingly, a network device determines the first time information based on the DCI; determines, based on the first time information and the time unit in which the DCI is located, a time unit for receiving the RS; and receives the RS in the determined time unit for receiving the RS.
