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 existing technology, thereby reducing the quality of uplink data transmission

Abstract

The present invention provides a method for determining uplink transmission power and user equipment. In the present invention, the user equipment determines the overlap between the uplink channel of the cell in the current subframe and the uplink channel of other cells performing carrier aggregation with the above cell in the adjacent subframe, so that the above user equipment can determine the above current channel according to the determined overlap. The transmission power of the PUSCH of the above-mentioned cell in the subframe and other cells performing carrier aggregation with the above-mentioned cell in the above-mentioned current subframe can avoid the problem that the uplink power control of the user equipment according to the existing technology is not accurate enough, thereby improving the uplink data transmission. the quality of.

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 (CarrierAggregation, 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 send...
