摘要： Embodiments of this application provide a paging method and apparatus. The 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. Therefore, 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. In this way, the terminal device may receive, in one discontinuous reception period, a paging message for a plurality of times, thereby increasing a speed of transmitting the paging message.

摘要： The present invention provides an uplink power control method, user equipment, and a base station. The user equipment includes: a receiver, configured to receive first radio resource control protocol RRC configuration information sent by a first base station, where the first RRC configuration information includes a parameter used to calculate a power headroom PH that is of the UE and that is in a first cell controlled by the first base station; and a transmitter, configured to send second RRC configuration information to a second base station, where the second RRC configuration information includes the parameter used to calculate the PH that is of the UE and that is in the first cell. The user equipment provided in the embodiments of the present invention is applicable to a scenario in which both RRC functions of two cells are controlled by means of RRC of one base station, and moreover, when two base stations use independent RRC, transmit power of the UE can also be effectively controlled, thereby improving uplink power control compatibility.

摘要： Embodiments of the present invention provide a method and an apparatus for controlling a serving grant of a user terminal UE of a neighboring cell, and a user terminal, a base station, a radio network controller and a communication system having this apparatus. The method is used for controlling a UE in a CELL-FACH state or in an idle state of a neighboring cell of each cell through a common E-RGCH channel of each cell, where the UE in the CELL-FACH state or in the idle state obtains a control command by monitoring a common E-RGCH channel of a neighboring cell of a cell to which the UE belongs, thereby adjusting a serving grant of the UE. The method includes: further setting at least one controlled condition; determining whether the UE satisfies the at least one controlled condition; and when the UE satisfies the at least one controlled condition, adjusting a serving grant of the UE based on the obtained control command. Through the method and the apparatus for controlling a serving grant of a UE of a neighboring cell according to the embodiments of the present invention, interference control may be performed on the UE in the CELL-FACH state or in the idle state of the neighboring cell, and at the same time, throughput of the UE may be prevented from being reduced excessively, thereby improving communication performance.
