Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0035] Such as figure 2 Shown is a schematic structural diagram of the UE described in the present invention, including a cache module, a control module, a measurement module, and a radio frequency data module;

[0036] The buffer module is used to store the FFT value and FFT reciprocal value of the Midamble code of the TS0 time slot of the TD-SCDMA wireless subframe;

[0037] The control module is used to determine whether the measurement resource is available after receiving the measurement command, and if so, set the activation flag position of the measurement module to 1; otherwise, after waiting for the measurement resource to be available, set the activation flag position of the measurement module to 1. 1; used for power conversion and filtering of the received PCCPCHRSCP measurement value;

[0038] The radio frequency data ...

Abstract

The invention relates to a user terminal and a method for measuring PCCPCHRSCP (Primary Common Control Physical Channel Received Signal Code Power). The user terminal comprises a cache module, a control module and a measuring module. The method comprises the following steps of: caching FFT (Fast Fourier Transform) and a reciprocal of the FFT of basic Midamble codes of all measuring cells in advance by the user terminal; after receiving a measuring command, carrying out channel estimation on all the measuring cells according to the cached FFT and the reciprocal of the FFT of the basic Midamble codes; and calculating the PCCPCHRSCP of the corresponding cell according to a channel estimating result. The invention improves the measuring precision and reduces the calculation amount and power consumption.

Description

technical field [0001] The invention relates to the field of TD-SCDMA (Time Division Synchronous Code Division Multiple Access), in particular to a user terminal (UE) and a method for measuring PCCPCH (Primary Common Control Physical Channel) RSCP (Received Signal Code Power). Background technique [0002] In the TD-SCDMA mobile communication system, the physical layer needs to perform cell measurement in different processes such as idle mode, random access mode, and business mode. All these cell measurements are performed by the upper layer protocol stack according to the signal strength of the current serving cell. Decides whether to start the associated measurement. Cell measurement includes serving cell measurement, same-frequency adjacent cell measurement, and inter-frequency adjacent cell measurement, among which the most important measurement quantity is RSCP. RSCP is used to identify the strength of the cell signal. The user terminal (UE) tracks the signal of the se...
