[0011] 5. Retransmission Timer: Only applicable to DL
For LTE Rel-8 UE only works on one CC, so the DRX mechanism of LTE can be used on its working CC, but since Rel-10 UE can work on multiple carriers at the same time, it needs to consider the existing How to perform DRX for Rel-10UE in the PDCCH mode, the deficiency of the existing technology is that there is no DRX solution under CA for Rel-10UE at present

Embodiment 1

[0135] This embodiment is the method of combination 1. The basic idea of ​​this embodiment is: the base station configures only one set of DRX parameters for a UE for the PDCCH CC subset, and the maintenance of each DRX timer is also for the UE. The maintenance process of each timer is as follows:

[0136] On duration timer: The start time of the On duration timer is consistent with the calculation method of the LTE system. The on duration start time and duration.

[0137] Inactivity Timer: After DRX is configured, the timer is turned on when the UE receives the control signaling of HARQ initial transmission within the time allowed to monitor the control channel (Active Time). Before the timer expires, the UE continuously monitors the PDCCH CC subset , if before the Inactivity Timer expires, as long as the UE receives the HARQ initial transmission control signaling on any CC on the supported PDCCH CC subset, it will terminate and restart the Inactivity Timer for the UE PDCCH C...

Embodiment 2

[0145] This embodiment is the way of combination 3, and embodiment 2 can be regarded as an optimization of embodiment 1, that is, the Active Time of all CCs in the PDCCH CC subset is equal to the sum of the Active Time of all PDSCH CC subsets that may be scheduled by it, but the PDSCH CC The DRX mechanism on each CC in the subset set is maintained independently, and is not affected by the PDCCH CC subset set.

[0146] Figure 10 It is a schematic diagram of DRX parameter configuration in Embodiment 2. In the figure, CC1 and CC2 are PDSCH CCs, CC3 and CC4 are PDCCH CCs, and the DRX timers on all CCs in the PDCCH CC subset are maintained uniformly, as shown in the figure:

[0147] t1: The UE receives the scheduling signaling for the initial transmission a of CC2 on CC4, then the UE starts the DRX Inactivity timer and the HARQ RTT timer for the process a on the PDCCH CC subset;

[0148] t2: The UE receives the control signaling for the initial transmission b of CC1 on CC3, then ...

Abstract

The invention discloses a discontinuous reception processing method and discontinuous reception processing equipment. The discontinuous reception processing method comprises that: in a multicarrier aggregation system, an evolved NodeB (eNB) determines to send a Physical Downlink Control Channel (PDCCH) CC set used aiming at a scheduling signaling of certain User Equipment (UE) and determines a Physical Downlink Shared Channel (PDSCH) CC set required for use and the number of PDSCH CC activated in the PDSCH CC at any time according to a data rate required by the UE; the eNB sends the scheduling signaling to the UE according to a Discontinuous Reception (DRX) parameter through the PDCCH CC set, wherein the scheduling signaling indicates at which time-frequency resources of the PDSCH CC set the UE receives data; and the UE periodically monitors the PDCCH CC set according to the DRX parameter, and receives the data on the PDSCH CC set according to the scheduling signaling acquired by the monitoring. Through the mode, the scheme provided by the method provides a discontinuous reception mechanism under a multicarrier aiming at Rel-10UE, and the mechanism is suitable for PDCCH 1a and PDCCH 1b, and can ensure flexible scheduling and effectively save the power at the same time.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a discontinuous reception processing method and equipment. Background technique [0002] 1. Brief introduction of DRX (Discontinuous Reception, discontinuous reception) process in LTE (Long Term Evolution, long term evolution). [0003] In a mobile communication system based on shared channels, such as LTE, the transmission of uplink and downlink data is controlled by the base station (eNB) scheduler. When the scheduler determines to schedule a certain user, it will notify UE (User Equipment, user equipment) through the control channel On which resource to send or receive data. The UE monitors the control channel, and when it detects the scheduling signaling directed at itself, it completes data transmission (uplink) or reception (downlink) according to the scheduling signaling on the control channel. In the activated state, since the terminal is not sure when the eN...
