Problems solved by technology

The purpose of this is to reduce the requirements for software / hardware processing power, but the price paid is the time it takes to perform the first step of the initial cell search
At the same time, with this method, the RF / ABB module needs to be turned on during the first step of the cell search, which consumes a lot of power for mobile phones.

Embodiment Construction

[0055] pass below Figure 4 to Figure 5 A specific embodiment of the present invention is described in detail, so as to further understand the content of the present invention.

[0056] Such as Figure 5 Shown: the user terminal in the time division synchronous code division multiple access system of the present invention carries out the method for initial cell search first step, comprises the following steps:

[0057] Step 1, clear the counters K, m, J used in the calculation process, and clear the memory used in the calculation process. The counter K is used for counting subframes, the counter m is used for counting time slices, and the counter J is used for counting the average number of subframes.

[0058] Step 2, the user terminal (UE) receives the signal belonging to the mth time slice of the Kth subframe (starting from the 0th subframe), and adds one to the value in the counter K.

[0059] Step 3, the user terminal (UE) makes sliding correlation between the input sig...

Abstract

This invention relates to a method for carrying out first step searching to the initial areas of a user terminal including the following steps: dividing data of each sub-frame into M time slices, receiving signals in the M time slices in the continuous sub-frames and using the received signals of the sub-frames to slide the down synchronous codes orderly to accumulate the related results to get the maximum value of the related results of the time slices and its related down synchronous code and the position, taking the down synchronous code corresponding to the maximum value in M maximum values as the detected one for the first step of area research and getting the head position of the sub-frame detected for the area searching by the time slice and position information corresponding to the maximum value.

Description

[0001] This application is a divisional application, [0002] Original application number: 200510027739.2 [0003] Original filing date: July 14, 2005 [0004] Invention title of original application: Method for the first step of initial cell search in time division synchronous code division multiple access system technical field [0005] The present invention relates to a method applied to a wireless communication system, in particular to a method applied to a Time Division Synchronous Code-Division Multiple Access (TD-SCDMA) mobile communication system, where a user terminal performs an initial cell search The method of the first step (Initial CellSearch Stepl). Background technique [0006] In 1946, Bell Laboratories in the United States proposed to divide the service area of ​​mobile phones into several cells, and set up a base station in each cell to form a new concept of cellular (Cellular) mobile communication in a cellular system. In 1978, this system was successf...
