Problems solved by technology

OFDM system bandwidth is generally divided into multiple levels, such as 5MHz, 10MHz, 15MHz and 20MHz. In this way, P-SCH only uses 1.08MHz of it, and the rest of the bandwidth will be idle and wasted, and the larger the system bandwidth, the more serious the waste of resources.

Embodiment Construction

[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0059] The method and device for improving the utilization rate of downlink pilot frequency (DwPTS) time slot resources in this time division duplex system of the present invention, in order to improve the frequency resource utilization rate of DwPTS, first set the information that needs to be sent in the idle frequency band of the DwPTS time slot, Then use the idle frequency band of the DwPTS time slot to send the set information to the user terminal, and the user terminal receives the set information in the idle frequency band of the DwPTS time slot.

[0060] Among them, setting the information that needs to be sent in the free frequency band of the DwPTS time slot has two implementation methods: one is to pre-set the information that needs to be sent ...

Abstract

The invention provides a method for improving the resource utilization rate of a downlink pilot time slot (DwPTS) by a time division duplexing system. The method comprises the following steps: firstly, information sent in an idle frequency band of the DwPTS is set, then the idle frequency band of the DwPTS is used for sending the set information to a user terminal, and the user terminal receives the set information in the idle frequency band of the DwPTS. The invention further provides a device corresponding to the method for improving the resource utilization rate of the DwPTS by the time division duplexing system. Compared with the prior art, the method and the device can improve the frequency resource utilization rate of the DwPTS, reduce waste of the DwPTS resources, increase the use of the DwPTS, and cause no impact on the data transmission rate of the conventional time slots.

Description

technical field [0001] The invention relates to resource utilization technology of a time division duplex (TDD) system, in particular to a method and a device for improving the resource utilization rate of a downlink pilot (DwPTS) time slot in a time division duplex system. Background technique [0002] Time Division Synchronous Code Division Multiple Access (TD-SCDMA) is the only technology that adopts Time Division Duplex (TDD) among the three major international standards of the third-generation mobile communication system. Its evolution system is a system based on OFDM adjustment. The TDD system The preferred frame structure is the second frame structure among the two frame structures determined to be supported by the LTE system. [0003] The basic second type of frame structure is as figure 1 Shown: the frame length of the second type of wireless frame is 10ms, and each wireless frame is split into two half-frames of 5ms. Each half frame consists of TS0~TS6( figure 1...
