Embodiment Construction

[0046] Aiming at the problem of low utilization efficiency of system resources existing in the prior art, the base station provided by the embodiment of the present invention stores the corresponding relationship between the frame structure parameters and the cell type, and determines the type of the covered cell according to the network environment; according to the determined cell type Determine the frame structure parameters, configure the frame structure according to the determined frame structure parameters, and send the determined frame structure parameters through broadcast. Thereby, the above-mentioned problems are solved.

[0047] Such as figure 2 As shown, the time division duplex wireless communication base station in the embodiment of the present invention includes: a storage module 100 , a processing module 110 , a configuration module 120 and a sending module 130 .

[0048]The storage module 100 is connected with the configuration module 120 and is used for sto...

Abstract

The invention discloses a method for configuring frame structure and the corresponding relationship between parameters of the frame structure and cell types is set. The method comprises the steps as follows: A. the type of the cell to be covered is confirmed according to the network environment; B. the parameter of the frame structure is confirmed according to the confirmed type of the cell, and the frame structure is set according to the confirmed parameter of the frame structure, which is sent out by broadcast. For the micro-cell environment, the invention adopts the proposal of reducing cyclic prefixes so as to obtain the required guard space between switching points of uplink and downlink, while for the macro-cell environment, the invention adopts the proposal of reducing the use of OFDM symbols in the time slot so as to obtain the required guard space between switching points of downlink and uplink. The invention solves the problem existing in the prior art that the utilization efficiency of system resources is low. The invention also discloses a base station.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a base station and a method for configuring a frame structure of a time division duplex system. Background technique [0002] In the advanced International Mobile Telecommunications / Internet Mobile Telecommunications (IMT-Advanced) system of the International Telecommunications Union (International Telecommunications Union: ITU), the maximum wireless communication bandwidth can reach 100 MHz. Through broadband wireless communication, users can enjoy high-speed data download, online shopping, mobile video chat, mobile TV and many other wireless mobile services. The maximum transmission rate of the IMT-Advanced system can reach 1Gbps, which greatly meets the needs of users for wireless mobile communications. [0003] For wireless communication bandwidth, the use of time division duplex (TDD) does not require paired frequencies, and various frequency resources can be u...
