Embodiment 1

[0043] In the evolved network, the downlink transmission of the eNodeB adopts OFDM modulation, the data transmission is carried out in units of frames, and the multiple access method adopts OFDMA / TDMA. In order to perform effective inter-cell interference management, different cells in the evolved network are strictly synchronized in time. The format of the downlink OFDMA data frame carrying cell load information provided by the present invention is shown in FIG. 5 .

[0044] The downlink data frame format of the present invention has three parts at the beginning of each frame: main preamble, secondary preamble and broadcast information. The three parts are described as follows:

[0045] Primary preamble: It is a pseudo-random sequence modulated on subcarriers, mainly used for cell synchronization. In order to ensure fast cell synchronization, all cells use the same sequence. The main preamble generally only occupies one OFDM symbol.

[0046] Secondary preamble: It is a gr...

Embodiment 2

[0066] The base stations of the local cell and neighboring cells continuously send downlink frames, which contain the quantized load information of the cell; in order to avoid the problem of inaccurate PN sequence phases caused by path transmission delays, it may be considered not to represent the initial phase Instead, select a group of mutually orthogonal codes, divide them into several disjoint subsets, assign different subsets to each cell, and a code in each subset represents a state of load information, so that the terminal The load information can be obtained only by knowing the received code.

[0067] The terminal analyzes the load information of each cell, first determines the downlink information of several cells that can be used according to the correlation peak, and then obtains the quantized load information of these cells according to the phase of the correlation peak, and makes the following judgment: If the analyzed If the first N / 2 bits of the N-bit quantizati...

Embodiment 3

[0072] As shown in FIG. 8 , the present invention also provides a system for acquiring radio resource management information in an evolved network, including: user equipment (UE), a base station in a local cell, and a base station in a neighboring cell; the user equipment has radio resource management information A transceiver device; wherein: the wireless resource management information includes adjacent cell resource information, and the adjacent cell resource information includes: adjacent cell resource load information, adjacent cell wireless resource allocation information, and availability status of adjacent cell wireless resources , the following takes the resource load information of adjacent cells as an example to illustrate:

[0073] (1') The base stations of the current cell and the neighboring cell continuously transmit downlink frames, and the downlink frames include quantized resource load information of the cell;

[0074] (2') The resource load information analy...

Abstract

The provided obtaining method for wireless resource management message in evolution network is to use a UE to obtain the wireless resource management message from near subzone and send to local BS for process. This invention completes task with less cost since no signaling interaction.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to wireless resource management between base stations in a wireless evolution network, and specifically to a method and system for acquiring wireless resource management information in an evolution network. Background technique [0002] The Universal Mobile Telecommunications System (UMTS) is a third-generation mobile communication system using WCDMA air interface technology, and the UMTS system is usually called a WCDMA communication system. The UMTS system adopts a structure similar to that of the second generation mobile communication system, including a radio access network (RAN) and a core network (CN). Among them, RAN is used to handle all wireless-related functions, while CN handles all voice calls and data connections in the UMTS system, and realizes switching and routing functions with external networks. CN is logically divided into circuit switched do...
