Embodiment 1

[0032] see Figure 1-a , this embodiment provides a method for discontinuous reception, the method may be specifically executed by the UE, including:

[0033] S11: Receive a PDCCH command or a MAC (MediumAccessControl, medium access control) CE (ControlElement, control element) command sent by the base station, the PDCCH command includes: first indication information and / or second indication information, and the MACCE order includes: the first One indication information and / or second indication information, wherein the first indication information is used to notify the user equipment UE that the base station will no longer schedule new data packets for the UE in the current discontinuous reception DRX cycle, and the second indication information uses Notifying the UE that the base station will no longer schedule a downlink HARQ retransmission for the UE within the current DRX cycle;

[0034] S12: According to the first indication information, at any time between the current su...

Embodiment 2

[0043] see figure 2 , this embodiment provides a discontinuous reception method, including:

[0044] 101: The base station sends a PDCCH command or a MACCE command to the UE. The PDCCH command includes: first indication information, and the MACCE command includes: first indication information. The first indication information is used to notify the UE that the base station will no longer schedule new DRX for the UE within the current DRX cycle. data pack.

[0045] Specifically, the base station may send a PDCCH command to the UE when scheduling new data packets for the last time in the current DRX cycle, that is, the PDCCH command is a PDCCH command for the base station to schedule new data packets for the last time in the current DRX cycle.

[0046] Wherein, the first indication information may be indication information of "last new data packet scheduling in the current DRX cycle", indication information of "terminate DRX-InactivityTimer", or indication information of "do no...

Embodiment 3

[0061] see image 3 , this embodiment provides a discontinuous reception method, including:

[0062]201: The base station sends a PDCCH command or a MACCE command to the UE. The PDCCH command includes: second indication information, and the MACCE command includes: second indication information. The second indication information is used to notify the UE that the base station will no longer schedule downlink for the UE within the current DRX cycle HARQ retransmission.

[0063] Specifically, the base station may send a PDCCH command when scheduling the last data packet retransmission in the current DRX cycle, that is, the PDCCH command is a PDCCH command for the base station to schedule the last data packet retransmission in the current DRX cycle.

[0064] Wherein, the second indication information may be indication information of "scheduling the last data packet retransmission in the current DRX cycle", indication information of "terminating DRX-RetransmissionTimer", or indicat...

Abstract

The invention discloses a discontinuous reception method and a device for the same and belongs to a communication technology field. The method comprises receiving a PDCCH or an MAC CE command transmitted by a base station, wherein the PDCCH or the MAC CE command comprises a first indication information and / or a second indication information, wherein the first indication information is used for notifying a UE base station of no longer scheduling new data packets for the UE in a current DRX period, and the second indication information is used for notifying the UE base station of no longer scheduling downlink HARQ retransmissions for the UE in the current DRX period; terminating or stopping restarting a DRX static timer based on the first indication information at any time from a current subframe or a first subframe after the current subframe to a first preset value; and terminating or stopping restarting a DRX retransmission timer based on the second indication information at any time from the current subframe or the first subframe after the current subframe to a second preset value to make the UE enter a sleep state as soon as possible. According to the invention, the UE is made to enter the sleep state as soon as possible through the above scheme, such that power consumption is saved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a discontinuous reception method and device. Background technique [0002] In order to save power consumption of UE (User Equipment, user equipment), a DRX (Discontinuous Reception, discontinuous reception) technology is introduced in an LTE (Long Term Evolution, long term evolution) system. [0003] In LTE DRX technology, at the beginning of each DRX cycle, the UE first starts the onDurationTimer (duration timer), and within the onDurationTimer time, the UE needs to monitor the PDCCH (PhysicalDownlinkControlChannel, physical downlink control channel) channel to obtain scheduling information. If the UE does not receive any scheduling information within the onDurationTimer, the UE enters a sleep state and stops monitoring the PDCCH channel. If within the onDurationTimer time, the UE receives scheduling information on the PDCCH channel, when the base station schedul...
