Problems solved by technology

[0003] However, since the transmission path of the uplink signal of the user equipment to the base station through different cells may be different, for example, the user equipment may need to pass through the relay node to send the uplink signal to the base station through some cells, while sending the uplink signal to the base station through other cells It may not need to go through the relay node, so the uplink transmission time of the user equipment may be different, which leads to the inaccurate uplink power control performed by the UE according to the prior art, thereby reducing the quality of uplink data transmission

Abstract

The invention provides an uplink sending power determining method and user equipment. Overlap of an uplink channel of a cell inside a present subframe and uplink channels of other cells, which perform carrier aggregation with the cell, inside an adjacent subframe is confirmed through the user equipment, and sending power of the cell in the present subframe and a physical uplink shared channel (PUSCH) of the other cells, which perform carrier with the cell, inside the present subframe, is confirmed by the user equipment according the confirmed overlap. The problems that uplink power control which is carried out according to the prior art by the user equipment is not accurate enough can be avoided, so that quality of sending uplink data is improved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method for determining uplink transmission power and user equipment. Background technique [0002] In a wireless communication system with a cell aggregation (Carrier Aggregation, CA for short) feature, a user equipment can communicate with a base station through multiple cells. In the uplink transmission process, in order to ensure that the uplink signals of all user equipments under the base station reach the base station synchronously, the base station can adjust the time when the user equipment sends the uplink signal, that is, the uplink transmission time, according to the deviation of the arrival time of the uplink signal of the user equipment. [0003] However, since the transmission path of the uplink signal of the user equipment to the base station through different cells may be different, for example, the user equipment may need to pass through the relay node to sen...
