    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.

    Abstract: This application relates to the field of wireless communications technologies, and in particular, to a sounding reference information (SRS) transmission method, to resolve a problem of when to transmit an SRS. In the method, user equipment (UE) receives SRS resource configuration information sent by a base station. The UE receives downlink control information (DCI) sent by the base station. The UE sends an SRS in a determined slot and symbol, where the determined symbol is determined by the UE based on the SRS resource configuration information.

    Abstract: An embodiment of this application provides a method for transmission in a time interval. The time interval includes one or more first time units and one or more second time units. The one or more first time units are used to transmit a first-type signal, and a quantity of first time units is associated with a quantity of first-type signals. The one or more second time units are used to transmit a second-type signal. In the method, a receiving node may obtain time unit information, where the time unit information is used to obtain a location of the one or more second time units, that is, determine a time domain location of the second-type time-frequency resource in the time interval. Then, the receiving node may receive or send the second-type signal on the second-type time-frequency resource.

    Abstract: A reference signal transmission method includes: sending, by a terminal, a first reference signal and a second reference signal; and correspondingly, receiving, by a network device, the first reference signal and the second reference signal, where the first reference signal is mapped to a plurality of symbols and is used for estimation of channel state information, the second reference signal is mapped to at least two of the plurality of symbols and is used for phase tracking, and a subcarrier to which the second reference signal is mapped on one of the at least two symbols has a same frequency-domain location as a subcarrier to which the second reference signal is mapped on the rest of the at least two symbols. With the foregoing solution, accuracy of channel state information estimation can be improved.

    Abstract: Embodiments of the present application disclose a sounding reference signal configuration method and an apparatus. The method includes: determining, by a base station, a movement speed of user equipment UE; determining, by the base station based on the movement speed of the UE, a UE-specific subframe configuration set in a plurality of UE-specific SRS subframe configuration sets corresponding to a used cell-specific SRS subframe configuration set, and determining a UE-specific SRS subframe configuration parameter in the determined UE-specific subframe configuration set, where the UE-specific SRS subframe configuration parameter is used to indicate a subframe used to send an SRS; and sending, by the base station, the UE-specific SRS subframe configuration parameter and identification information of the UE-specific subframe configuration set to the UE.
