Abstract: A method includes: determining, by a terminal device within a discontinuous reception period, an occasion set for paging of the terminal device based on a terminal device identifier, where the occasion set for paging includes at least two occasions for paging; and receiving, in a time range corresponding to the occasions for paging included in the occasion set for paging, a paging message. One discontinuous reception period is partitioned into a plurality of occasion sets for paging, and one occasion set for paging includes at least two occasions for paging. After determining, within a discontinuous reception period, a corresponding occasion set for paging, the terminal device may receive a paging message on an occasion for paging included in the occasion set for paging.

Abstract: A power allocation method and apparatus belong to the field of communications technologies. The method includes: determining, by UE, a first start time point of a first control subframe and a second start time point of a second control subframe; determining, based on the first start time point and the second start time point, whether a priority of a first target subframe is higher than a priority of a second target subframe; and if the priority of the first target subframe is higher than the priority of the second target subframe, allocating, based on first uplink channel information and second uplink channel information, power to the UE in a base station or a cell group in which the first target subframe is located, and allocating reserved power of the UE to the UE in a base station or a cell group in which the second target subframe is located.

Abstract: According to a resource configuration method, user equipment, and a base station that are provided in embodiments of the present invention and relate to the communications field. A specific solution is as follows: A base station sends M reference signals to UE in N time units in a time unit set, where the reference signal is used by the UE to perform channel quality measurement, and each reference signal in the M reference signals is corresponding to one piece of precoding matrix information. The base station receives channel quality indication information sent by the UE.

Abstract: Embodiments of the present invention provide a method for determining a precoding matrix indicator, a receiving device, and a sending device. The method for determining a precoding matrix indicator includes: selecting, by a receive end, a precoding matrix W from a codebook based on a reference signal sent by a transmit end, where the precoding matrix W is a product of two matrices W1 and W2, where the W1 includes NB block matrices Xi, NB≥1, and the W1 is indicated as: W1=diag{X1, . . . , XNB}, where 1≤i≤NB, and a column xi,j of each block matrix Xi is a Kronecker product of a first vector Aij and a second vector Bij, that is, xij=Aij⊗Bij; and sending, by the receive end, a precoding matrix indicator PMI corresponding to the precoding matrix W to the transmit end, so that the transmit end obtains the precoding matrix W according to the PMI.

Abstract: The present invention provides a signal sending apparatus, a signal detection apparatus, a signal sending and detection system, a signal sending method, and a signal detection method. The apparatus determines a time unit that is in each time window and that is used to transmit a synchronization signal, and transmits the synchronization signal in the determined time unit in each time window. Therefore, a synchronization signal is always located in a time unit that has a fixed location in each time window, so that a device at a receive end needs to perform detection only in a fixed time unit in each time window, thereby reducing complexity of designing and detecting the synchronization signal.

Abstract: In a 3D MIMO scenario with 16 antenna ports, antenna ports can be extended in different directions because of different configuration manners of the antenna ports. An apparatus and method where different antenna port counting manners are determined in different configurations are provided, so that in different configurations, a matrix whose dimension is 8 and a matrix whose dimension is 2 are determined in a precoding codebook, and a value of a PMI is fed back to indicate a precoding matrix.
