Abstract

The present invention discloses a method for reducing transmission power at a user side in a dual/multiple-connection wireless communication system, wherein: according to a type of a channel and/or data transmitted in the channel, setting a primary priority for the channel; according to a base station corresponding to the channel and/or a link connected to the base station, setting a secondary priority for the channels having the same primary priority; and when the entire transmission power of the user apparatus exceeds maximum transmission power allowed by the user apparatus, according to the primary priority and the secondary priority, reducing the transmission power for parts of or all of the channels.

Description

technical field [0001] The present invention mainly relates to communication technology, in particular to a method for reducing transmission power of user equipment in a multi / dual connection wireless communication system. Background technique [0002] Since low-power nodes can bring gains in terms of capacity expansion and blind spot coverage, more and more research focuses on the deployment and enhancement of small cells covered by low-power nodes. Here, the low-power node may be a small base station, examples of which include but are not limited to low-power base stations such as Pico and Femto. In 3GPP R12, a new research project "Small Cell Enhancements for E-UTRA and E-UTRAN Higher-layer aspects" has been approved, and One of the key points is to support dual / plural connectivity between a macro cell (a cell covered by a macro base station) and a small cell. [0003] Since there are at least two connections in the multi-connection wireless communication system, in the...
