Abstract

The invention provides a method of controlling transmission power of a user equipment side on a base station side supporting TDD eIMTA (Enhancement to LTE TDD for DL-UL Inference Management and Traffic Adaptation), and an apparatus thereof. A specific subframe on the base station side jointly schedules an (n+k) UL subframe and an (n+7) UL subframe on the user equipment side, wherein the specific subframe sends a TPC command to the user equipment side so as to control transmission power of the (n+k) UL subframe and the (n+7) UL subframe on the user equipment side, wherein the TPC command respectively indicates a closed loop power control value of the (n+k) UL subframe, and a closed loop power control value of the (n+7) UL subframe. The invention also provides a method of controlling transmission power on A user equipment side supporting TDD eIMTA, and an apparatus thereof.

Description

technical field [0001] The present invention mainly relates to the technical field of wireless communication, and in particular, relates to a method and device for controlling uplink subframe transmission power of a user equipment side under the condition of supporting eIMTA. Background technique [0002] In the time division duplex (TDD) eIMTA (Enhancements to LTE TDD for DL-ULInterference Management and Traffic Adaptation) work item of release 12, for uplink / downlink HARQ, the following agreements have been reached: [0003] - For uplink, scheduling and HARQ timing follow the TDD uplink-downlink configuration sent in System Information Block 1 (SIB1). [0004] - The downlink HARQ reference configuration can be selected from the TDD uplink-downlink configuration {2, 4, 5} of Release8. [0005] In the current TDD standard, for TDD configuration 0, the 2-bit uplink index in the uplink grant (UL grant) is used to perform multi-subframe scheduling, as shown in Section 8.0 of 3...
