    Abstract: Embodiments disclose a reference signal transmission method and an apparatus. The method includes receiving reference signal resource configuration information sent by a base station, where the reference signal resource configuration information includes antenna port quantity information and a resource configuration index. The method also includes determining a reference signal configuration from a reference signal configuration set according to the antenna port quantity information and the resource configuration index. The method also includes obtaining, according to the determined reference signal configuration, positions of the resource elements (REs) that are used to send the reference signal on the antenna ports in the antenna port set, and receiving reference signals according to the positions of the REs.

    Abstract: This application relates to the field of wireless communications, and in particular, to a communication method, an apparatus, and a system in a wireless communications system. In the method, a network device and a terminal device determine M resource element group bundles in a control resource set. The network device sends a control channel on resources corresponding to the M resource element group bundles. The terminal device detects the control channel on the resources corresponding to the M resource element group bundles, where M is greater than or equal to 1. The control resource set includes B resource element group resource element group bundles. By using the method, resource configuration efficiency in a communications system is improved.

    Abstract: Example methods and apparatus for sending an uplink control channel and receiving an uplink control channel are described. One example method for sending an uplink control channel includes determining a resource set to be used for an uplink control channel by a terminal device, where the uplink control channel carries uplink control information and a demodulation reference signal (DMRS). The resource set includes N resource subsets, each of the N resource subsets includes a plurality of consecutive symbols in time domain, and N is greater than or equal to 1. The terminal device determines, for each of the N resource subsets, a quantity of symbols used to carry the DMRS, where the quantity of symbols is one of at least two candidate symbol quantities. The terminal device sends the uplink control channel by using the resource set.

    Abstract: The present disclosure discloses a method, a user equipment and a base station for determining a PMI. The method includes: receiving a reference signal set sent by a base station; based on the reference signal set, selecting a precoding matrix from a codebook, the codebook at least including a non-constant modulus precoding matrix, the non-constant modulus precoding matrix at least including a non-constant modulus column vector, amplitude values of at least two elements of the non-constant modulus column vector forming a symmetrical sequence; and sending a PMI to the base station, the PMI corresponding to the selected precoding matrix. According to the method, the user equipment and the base station for determining PMI, because the non-constant modulus precoding matrix included in the adopted codebook can adjust the shape of a beam, antennas may focus power on a hotspot region, and thus a load balance may be effectively realized.
