specific Embodiment 1

[0070] The UE sleep wake-up processing flow of this specific embodiment is as follows figure 2 Shown:

[0071] In this embodiment, the UE needs 1 subframe to complete device stabilization, and p subframes are needed to restore timing synchronization;

[0072] 1. In the idle mode, the UE receives and interprets the system information, and obtains the position of the subframe where the physical channel under each system information block is located;

[0073] 2. The UE judges whether the arrival time of a subframe carrying a certain type of system information block is within a specific range. If yes, perform step 3; otherwise, perform step 9

[0074] Wherein, the specific range is the subframe where the PICH is located - T ~ the subframe where the PICH is located + T time range; T is the time required for the UE to measure the cell during this wake-up process;

Abstract

The present invention provides a processing method for sleep wakeup of a mobile terminal. UE interprets system information in idle mode to obtain the position information of each subframe carrying a certain type of system information block, and compares it with the position of the subframe where the PICH is located. When When the distance between the subframe carrying a certain type of system information block and the subframe where the PICH is located is within a specific range, reconstruct and obtain the corresponding symbol standard mapping position of the specific physical channel carrying a certain type of system information block in the subframe, and use The symbol standard mapping position and the joint detection and equalization output of the target code channel in the TSO time slot of the subframe perform frequency calibration based on standard symbol information reconstruction to realize frequency synchronization recovery. The method of the present invention utilizes known system information to perform frequency synchronization recovery during sleep wakeup, and improves the synchronization recovery performance of UE sleep wakeup without significantly increasing UE power consumption.

Description

technical field [0001] The present invention relates to the third-generation mobile terminal power saving technology, in particular to a processing method for mobile terminal sleep wake-up Background technique [0002] In a time division-synchronous code division multiple access (abbreviation, TD-SCDMA) system, a mobile terminal (abbreviation, UE) has two basic operation modes: an idle mode and a connected mode. UEs in idle mode are identified by the non-access stratum. In the TD-SCDMA system, there is no individual information about UEs in idle mode, and the network can only address and send messages to all UEs in the cell or all UEs listening to the same paging period. [0003] When the UE is in idle mode, before initiating a radio resource control (RRC) connection establishment application, it usually includes the following main work contents: [0004] - Receive system messages from Public Land Mobile Networks (PLMN for short) [0005] - Listen for paging [0006] -Ce...
