    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: This application provides a data transmission method and apparatus. The method includes: receiving, by a terminal device, a first reference signal sent by a network device; measuring, by the terminal device, a downlink channel based on the first reference signal, to obtain a channel status of the downlink channel; determining, by the terminal device, a target mode from a plurality of modes based on the channel status of the downlink channel, where information that is used to feed back channel state information (CSI) and that is sent by the terminal device in different modes of the plurality of modes is different; and sending, by the terminal device, indication information to the network device, where the indication information is used to indicate the target mode. The data transmission method and apparatus in the embodiments of this application are conducive to improve flexibility of feeding back CSI.

    Abstract: This application provides a communication method, a terminal device, and a network device. The method includes: using, by a terminal device, a first receive parameter to receive control information sent by a network device, where the control information is used to indicate a second receive parameter used by the terminal device to receive a to-be-transmitted signal; determining, by the terminal device based on a first antenna panel to which the first receive parameter belongs and a second antenna panel to which the second receive parameter belongs, a beam switching time required for switching from the first receive parameter to the second receive parameter; and receiving, by the terminal device, the to-be-transmitted signal based on the beam switching time.

    Abstract: A signal sending and receiving method includes: receiving, by a terminal device, at least one piece of resource configuration information for determining N reference signal resource groups, and each of the N reference signal resource groups includes at least one reference signal resource; and sending a reference signal on a resource in an ith reference signal resource group in the N reference signal resource groups by using a jth antenna group corresponding to the ith reference signal resource group, where the jth antenna group includes at least one antenna. The N reference signal resource groups correspond to N antenna groups, and any two of the N antenna groups are different.
