Abstract

The invention discloses a method for collocating a discontinuous receiving cycle starting point, including the following steps: offsets of the starting points of the DRX cycles of all users in a long-term evolution item time division multiplexing (LTE TDD) wireless frame are obtained, and the offsets of different users are distributed on a downlink subframe of the LTE TDD wireless frame; and the offsets of the starting points of the DRX cycles are sent to a corresponding user terminal. The invention also discloses a device for collocating a discontinuous receiving cycle starting point. The scheme of the invention enables the time for a plurality of terminals to start up the DRX to be evenly distributed on all downlink subframes in an LTE TDD system, thereby the equilibrium of the utilization ratio of downlink dispatching and downlink resources can be achieved.

Description

technical field

[0001] The present invention relates to the technical field of mobile communication, and in particular to a method and device for configuring a start point of a discontinuous reception (Discontinuous Reception, DRX) cycle. Background technique

[0002] In the Long Term Evolution (LTE) system of the 3GPP, a Discontinuous Reception (DRX) technology is introduced in a Radio Resource Control (Radio Resource Control, RRC) connection state. DRX means that the terminal discontinuously receives downlink scheduling and downlink data. When it does not need to receive downlink data, the terminal can be in a sleep state, and the radio frequency unit and even other processing units of the terminal can not work, so as to achieve the purpose of power saving.

[0003] The principle of periodic configuration of DRX is as follows: figure 1 shown. At the beginning of each DRX cycle, it first enters a short continuous receiving state, which is called an on-duration, and usuall...
