Embodiment Construction

[0045] The present invention provides a method for realizing the steady state of the relay station. The method is applied to a multi-hop wireless communication system.

[0046] Wherein, the multi-hop branch of wireless communication can be expressed as BSRSRSRSRSSS, where "" represents the radio link used by each station for communication. The number of RSs can be 0, 1 or more, and the number of SSs can be 0 or 1. The BS, RS and SS are called nodes, wherein the BS is the 0th hop node, which is i (i is a natural number) hop away from the BS The node is the i-th hop node; the i-1-th hop node is the parent node of the i-th hop node, the i+1-th hop node is the child node of the i-th hop node, and the BS has no parent node; BS and RS can be parent nodes. Node, RS can be a child node, and the last hop node has no child node.

[0047] In this system, the steady state of the relay station refers to the state in which the relay station can transmit information in a synchronous broadc...

Abstract

The invention provides a method for stabilizing a relay station and a transmission system as well as a transmission device, wherein, the method includes the following steps: the relay station obtains the frame number and the frame length of the current frame transmitted from a parent node in the control signaling of each frame broadcast, and designating the frame number receiving relay control signaling, and calculates the starting time of the designated frame; the relay station determines the starting time when the parent node transmits the relay control signaling in the designated frame; the relay station begins broadcasting pilot frequency, controlling signaling at the starting time of the designated frame, as well as receives the relay control signaling at the starting time of the parent node transmitting the relay control signaling in the transmission mode in accordance with transmission mode thereof. The invention realizes the stability of the relay station.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method, a transmission system and a transmission device for realizing the steady state of a relay station. Background technique [0002] With the continuous development of communication technology, the requirements for the access rate are also constantly increasing. In order to meet the requirements of the access rate, the broadband wireless access (BWA) method has been paid more and more attention by people. The communication system established based on the IEEE802.16e standard is a BWA communication system. [0003] In the 802.16e standard, wireless transmission is carried out between a base station (BS) and a subscriber station (SS). In order to enable the SS to send and receive data with the BS, the BS broadcasts a pilot (Preamble) and a control signal at the head of each frame. order (FCH, DL-MAP and UL-MAP), and broadcast the Downlink Channel ...
