Embodiment Construction

[0031] Hereinafter, the implementation of the method and device for frequency point power measurement in the cell search phase of the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0032] Figure 4 It is a schematic flowchart of a method for measuring frequency point power in the cell search phase of an embodiment of the present invention, as shown in Figure 4 As shown, the method includes:

[0033] Step 401: Preset the length of the data receiving block, determine the number of frequency points that can be measured in a subframe according to the length of the data receiving block, and divide the frequency points to be measured into several frequency point sets according to the number of frequency points.

[0034] Among them, when dividing the frequency point set according to the number of frequency points, the purpose is only to divide the frequency point to be measured into several parts according to the numbe...

Abstract

The invention discloses a method and device for measuring frequency point power during a cell-search stage. The method includes determining the number of frequency points, which can be measured in a subframe, according to a preset length of a data receiving block; dividing frequency points in need of measurement into frequency point sets according to the number of frequency points; carrying out the following processing on each frequency point set in sequence: determining receiving sequences of frequency points in the frequency point set, sequentially receiving data receiving blocks of each frequency point in the frequency point set according to the sequences, and cycling for preset cycle times; and calculating power of each frequency point according to the received data receiving blocks of each frequency point, wherein the number of the data receiving blocks is the cycle times. The method and device can shorten the total time of power measurement of all frequency points, and improve cell-search speed.

Description

technical field [0001] The invention relates to a frequency point power measurement technology, in particular to a method and device for frequency point power measurement in a cell search stage. Background technique [0002] In the TD-SCDMA (Time Division Synchronous Code Division Multiple Access) system, its wireless frame structure is generally as follows figure 1 As shown, one radio frame has a length of 10ms and is divided into two 5ms subframes. The structures of these two subframes are exactly the same. Such as figure 1 As shown, each subframe is further divided into 7 regular time slots and 3 special time slots. The three special time slots are DwPTS (downlink pilot time slot), GP (guard time slot) and UpPTS (uplink pilot time slot). Of the 7 regular time slots, TS0 is always allocated to the downlink and TS1 is always allocated to the uplink. The DwPTS in each subframe is designed for downlink pilot and synchronization. The time slot is composed of a SYNC_DL se...
