Abstract

The embodiment of the invention provides an uplink power control method based on movable sub frame under time division duplex (TDD) model. The method comprises the following steps: generating transmitting power of each uplink sub frame respectively according to the transmitting power of a pervious uplink sub frame of each uplink sub frame in a plurality of uplink sub frames, or the transmitting power of the pervious fixed uplink sub frame, wherein the uplink sub frames comprises at least one fixed uplink sub frame and at least one uplink sub frame configured by movable uplink sub frames. In the embodiment, the transmitting power of each uplink sub frame is generated in the presence of the sub frame including at least one fixed uplink sub frame and at least one uplink sub frame configured by the movable uplink sub frame, so that the power control under the condition including movable uplink sub frames is realized.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a flexible subframe-based uplink power control method and device in time division duplex TDD mode. Background technique [0002] LTE-A (LTE-Advance, evolution of LTE) is an enhancement of LTE (Long Term Evolution, long-term evolution) technology. LTE-A has higher bandwidth requirements than LTE and supports a peak data rate of up to 1G. Both LTE-A and LTE support two duplex modes of FDD (Frequency Division Duplex, frequency division duplex) and TDD (Time Division Duplex, time division duplex). [0003] In the TDD duplex mode of LTE-A, the sending and receiving signals are in the same frequency band, and the uplink and downlink signal frames are distinguished by sending them in different time periods on the time axis. A signal frame can include: downlink subframes , uplink subframe, special subframe and flexible subframe. Wherein, the flexi...
