Embodiment 1

[0034] Figure 2a A flow chart of a discontinuous reception (DRX) method provided in Embodiment 1 of the present invention, such as Figure 2a As shown, the discontinuous reception method includes:

[0035] Step 101, the user equipment receives the virtual scheduling activation indication sent by the base station on the physical downlink control channel PDCCH, and the virtual scheduling activation indication is used to perform virtual scheduling on the user equipment in the current subframe to prolong the activation opportunity of the user equipment ;

[0036] In the embodiment of the present invention, when the virtual scheduling is performed on the user data in the current subframe, there is no actual data to be transmitted, and only the virtual scheduling is used to prolong the activation opportunity of the user equipment to detect the PDCCH.

[0037] Using step 101, if the activation opportunity of the user equipment conflicts with the special subframe of the base statio...

Abstract

The invention discloses a discontinuous receiving method and equipment. The discontinuous receiving method comprises the following steps that a virtual scheduling activation instruction which is sent by a base station is received by user equipment on a PDCCH (Physical Datalink Control Channel); the virtual scheduling activation instruction is used for virtually scheduling the user equipment in a current subframe so as to prolong the activation time of the user equipment; and a deactivation timer of the user equipment is started by the user equipment according to the virtual scheduling activation instruction. The deactivation timer can be started by the UE (User Equipment) disclosed by the embodiment of the invention in the DRX (Discontinuous Reception) activation time according to the virtual scheduling activation instruction of the base station, thereby solving the problem of data transmission when the DRX activation time is occupied by a special subframe. The UE is instructed by the base station to perform conflict resolution, and therefore, power consumption of the UE can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a discontinuous reception method and device. Background technique [0002] The Long Term Evolution (LTE) research project led by the 3rd Generation Partnership Project (3rd Generation Partnership Project; 3GPP for short) is a new generation of wireless communication technology, expecting higher data throughput and better network performance. In the LTE system, the air interface is based on Orthogonal Frequency Division Multiplexing (OFDM) technology: a shared channel is used for communication between the base station and the terminal, and each UE does not have its own exclusive wireless resource, and the user equipment ( User Equipment (abbreviation: UE) does not know in advance when the base station sends data to itself. In the LTE system, the time axis is divided into several time slots. The most basic transmission time slice is a subfram...
