Definitions
- FIG. 1 is a schematic structural diagram of a power control apparatus according to an embodiment of the present invention.
- FIG. 6 is a flowchart of another power control method according to an embodiment of the present invention.
- the generating unit 11 is specifically configured to generate a third correspondence, where the third correspondence is resource information used by the transmission power control command, and the identifier information of the serving cell of the user equipment and/or the identifier information of the serving cell group. Correspondence.
- the sending unit 12 sends multiple power control commands respectively in a serving cell of the user equipment using resources corresponding to multiple power control commands according to the third correspondence generated by the generating unit 11, that is, sending multiple different commands on different resources. Power control commands.
- the receiving unit 21 is configured to receive a correspondence between a power control command sent by the base station and a serving cell and/or a serving cell group of the power control device, and configured to receive the service cell in a serving cell of the power control device. a plurality of power control commands sent by the base station; or the receiving unit 21, configured to receive downlink control information in a serving cell of the power control device, where the downlink control information includes: multiple power control commands, and the The identification information of the serving cell and/or the identification information of the serving cell group respectively corresponding to the multiple power control commands; or the downlink control information includes: multiple power control commands, and identification information of one serving cell and/or a serving cell group Identification information.
- the transmitting adjustment unit 22 is specifically configured to determine that multiple power control commands are used for The power control device is instructed to adjust the transmit power of the serving cell and/or the serving cell group identified by the identity information included in the downlink control information. If the downlink control information received by the receiving unit 21 includes: identification information of multiple serving cells and/or serving cell groups, and multiple power control commands, the transmission adjusting unit 22 is specifically configured to determine a power control command for indicating power. The control device adjusts the transmit power of the serving cell and/or the serving cell group identified by the identity information associated with the power control command.
- Step 201 The user equipment receives a power control command sent by the base station, and a corresponding relationship between the serving cell and/or the serving cell group of the user equipment, and receives a plurality of power control commands sent by the base station in a serving cell of the user equipment.
- the base station carries the multiple TPC commands in a downlink control information, that is, the DCI, and sends the information to the user equipment in the common search space of the primary cell to which the user equipment belongs, and includes, in multiple TPC commands, the user equipment to be transmitted in the primary cell.
- the user equipment uses the TPC command obtained by the first RNTI descrambling to adjust the transmit power of the PUCCH transmitted by the user equipment on the primary cell, and uses the TPC command obtained by the second RNTI descrambling to adjust the transmit power of the PUCCH transmitted by the user equipment on the first PSCell.
