Embodiment 1

[0040] An embodiment of the present invention provides a method for scheduling cell search and energy measurement tasks. The execution subject of the method may be software installed in the UE, and the scheduling strategy for the UE to perform cell search and energy measurement tasks is implemented by the software.

[0041] Such as figure 1 As shown, the above method specifically includes:

[0042] 101. Set the cycle for executing the cell search task to be the same as or be an integer multiple of the cycle for the energy measurement task;

[0043] 102. Comparing the execution time Tcs of the cell search task before scheduling and the execution time Tmeas of the energy measurement task, if Tcs is greater than Tmeas before scheduling, perform step 103, and if Tcs is less than Tmeas before scheduling, perform step 104;

[0044] 103. Adjust Tmeas according to the Tcs before scheduling, and obtain the execution time Tmeas of the energy measurement task after scheduling;

[0045]...

Embodiment 2

[0048]The embodiment of the present invention provides a method for scheduling cell search and energy measurement tasks, which is improved on the basis of embodiment 1, and the execution subject is the same as that in embodiment 1;

[0049] like figure 2 As shown, a method for scheduling cell search and energy measurement tasks specifically includes:

[0050] 201. Set the period for executing the cell search to be the same as or have an integer multiple of the period for performing the energy measurement;

[0051] It should be noted that the period of energy measurement is specified in the 3GPP_TS_25.133 protocol and is fixed. In this embodiment, Tmeas_period is used to represent the period of energy measurement, and the period for performing cell search is set as Tcs_period. Then it is set that the cycle of executing the cell search is the same as or has an integer multiple relationship with the cycle of energy measurement, specifically:

[0052] Tcs_period=N*Tmeas_period;...

Embodiment 3

[0087] This embodiment provides a device for scheduling cell search and energy measurement tasks, such as Figure 4 As shown, the device specifically includes:

[0088] The cycle setting module 301 is used to set the cycle of executing the cell search task to be the same as the cycle of the energy measurement task or have an integer multiple relationship;

[0089] The duration comparison module 302 is used to compare the execution duration Tcs of the cell search task before scheduling and the execution duration Tmeas of the energy measurement task;

[0090] The first adjustment module 303 is used to adjust Tmeas according to the Tcs before scheduling when the comparison module 302 obtains that Tcs is greater than Tmeas before scheduling, so as to obtain the execution time Tmeas of the energy measurement task after scheduling. ;

[0091] The second adjustment module 304 is used to adjust the Tcs according to the Tmeas before scheduling when the time length comparison module 3...

Abstract

The present invention discloses a method and device for scheduling cell search and energy measurement tasks, and relates to the field of communications. The present invention can ensure, by setting the period for carrying out the cell search task to be the same as or an integral multiple relationship of the period of the energy measurement, that the cell search task can be carried out when the energy measurement task is carried out, thus improving concurrency of the cell search task and energy measurement task, shortening the execution time of the total tasks and reducing the standby power of a UE, and the invention adjusts, according to one task with longer execution time which is one of the cell search task and the energy measurement task, the other task with shorter execution time, thus enhancing the performance of the UE for carrying out the cell search task and energy measurement task.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for scheduling cell search and energy measurement tasks. Background technique [0002] Standby power consumption is an important indicator of UE (User Equipment, user equipment) in a wireless communication network, especially an important performance indicator of a mobile phone. In the standby state, cell search and energy measurement are two essential tasks of the UE. Among them, the purpose of cell search is to provide accurate phase information for cell energy measurement. When the UE is in a dynamic scenario, the phase information of the cell is constantly changing, and it is necessary to perform cell search periodically to obtain the information of the cell where the UE currently resides, and then perform subsequent energy measurement. [0003] At the current stage, the cell search time and cell energy measurement time are fixed, and the cell search cy...
