Problems solved by technology

However, the current 3GPP MAC protocol TS 36.321 V8.2.0 only defines the relationship between the measurement gap and HARQ retransmission, that is, HARQ retransmission is not allowed during the measurement gap; the protocol does not define how to implement the priority relationship between the measurement gap and DRX

Embodiment Construction

[0045] The present invention notices that solving the conflict between DRX and measurement gap is mainly to solve the situation that measurement gap may occur during DRX activity time. During the DRX active time, the UE needs to monitor the PDCCH in the PDCCH subframe; while during the measurement gap time, the UE is not allowed to monitor the PDCCH and perform downlink / uplink transmission. Since the DRX active time is controlled by the duration timer or the DRX inactivity timer or the DRX retransmission timer or the contention resolution timer, when any one or more of the above timers are running, the UE is in the DRX active time.

[0046] The processing method when the present invention proposes discontinuous reception and measurement gap conflict is as follows:

[0047] If there is a measurement gap during the DRX active time, the terminal does not monitor the PDCCH within the overlapping time range of the DRX active time and the measurement gap.

[0048] Further, the term...

Abstract

The invention provides a method for processing conflict between the discontinuous receiving and the measurement clearance. If the measurement clearance exists in the discontinuous receiving of DRX activity time, a terminal does not monitor the physical downlink control channel PDCCH in a time range that the DRX activity time and the measurement clearance are overlapped. The invention also providesa method for processing conflict between the discontinuous receiving and the measurement clearance. When a contention resolution timer runs, the terminal cancels the measurement clearance if the measurement clearance exists. The invention provides a particular scheme for conflict between the measurement clearance and the DRX activity time, namely the PDCCH cannot be monitored in the time range that the DRX activity time and the measurement clearance are overlapped so as to solve the conflict existing in the current 3GPP protocol under the condition and make the priority relation of the DRX and the measurement clearance definite.

Description

technical field [0001] The invention relates to the technical field of digital mobile communication, in particular to a processing method when discontinuous reception and measurement gap conflicts in a wireless communication system. Background technique [0002] In the third-generation mobile communication Long Term Evolution (LTE for short) system, in order to save the battery / power consumption of the User Equipment (UE for short, also called the terminal), the system configures the discontinuous reception (Discontinuous reception) Reception, referred to as DRX) function. With DRX, the UE is allowed to stop monitoring the Physical Downlink Control Channel (PDCCH for short) within a certain period of time, that is, the UE is allowed to monitor the PDCCH intermittently. [0003] DRX functions include Long DRX cycle, DRX Inactivity Timer, DRX retransmission Timer, and may also include Short DRX Cycle and DRX short cycle timing (DRX Short CycleTimer). [0004] In order to de...
