Problems solved by technology

However, the uplink pilot signal in this way will occupy the uplink business time slot, resulting in a decrease in system data capacity
If the uplink pilot signal and uplink service data are concurrently used, the detection of the uplink pilot signal will reduce the performance of the base station, resulting in a decrease in the success rate of system access

Embodiment Construction

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The core idea of ​​the method provided by the present invention mainly includes: the mobile terminal sends the uplink pilot signal in the uplink pilot time slot (UpPTS) in the pre-appointed radio frame structure, wherein the UpPTS in the pre-appointed radio frame structure moves to two Between service time slots.

[0023] Correspondingly, the base station receives the uplink pilot signal on the UpPTS in the pre-appointed radio frame structure, where the UpPTS in the pre-appointed radio frame structure moves to between two service time slots.

[0024] In order to facilitate the understanding of the present invention, the location of the existing UpPTS is first briefly introduced, such as figure 2 As shown, there is a special time slot between t...

Abstract

The invention provides a method, a base station and a mobile terminal for sending and receiving uplink pilot signals, and the mobile terminal sends the uplink pilot signals on an uplink pilot time slot (UpPTS) in a predetermined wireless frame structure, wherein the UpPTS in the predetermined wireless frame structure is shifted backward to between two service time slots; and correspondingly, the base station receives the uplink pilot signals on the UpPTS in the predetermined wireless frame structure. The invention can reduce the influence of downlink signals of an adjacent base station on the local uplink pilot signals and ensure the system capacity and the success rate of access.

Description

Technical field [0001] The present invention relates to mobile communication technology, in particular to a method, base station and mobile terminal for sending and receiving uplink pilot signals. Background technique [0002] In the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, the time division duplex (TDD) mode is adopted to keep synchronization between different base stations. However, as the propagation distance increases, the downlink signals sent by the neighboring base stations may affect the local area The uplink pilot signal causes interference, which affects the normal operation of the base station. Such as figure 1 As shown, base station 2 and base station 3 are neighboring cell base stations of base station 1. After base station 2 delays t1, its downlink pilot signal will cause interference to base station 1’s uplink pilot signal; base station 3 after delay t2, its The downlink service data sent on the time slot TS0 will cause interferen...
