Embodiment Construction

[0045] The 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 wireless communication multi-hop branch may be expressed as BSRSRSRSRSSS, where "" indicates the wireless link used by each station for communication. The number of RS can be 0, 1 or more, SS can be 0 or 1, and 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 hop node is called the parent node of the i-th hop node, the i+1 hop node is the child node of the i-th hop node, and BS has no parent node; BS and RS can be the parent node node, RS can be a child node, and the last hop node has no child nodes.

[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 broadcast frame structure. Wherei...

Abstract

The invention provides a method for realizing the steady state of the relay station, a transmission system and transmission equipment. Wherein, the method includes: the relay station obtains the frame sequence number of the current frame sent by the parent node, the frame length and the frame sequence number of the frame designated to receive the relay control signaling from the control signaling broadcast by the parent node in each frame, Calculate the start time of the specified frame; the relay station determines the start time of the parent node sending the relay control signaling in the specified frame; the relay station broadcasts from the start time of the specified frame pilot and control signaling, and according to the transmission format of the relay control signaling sent by the parent node, the relay control signaling is received from the initial moment when the parent node sends the relay control signaling, and enters a steady state. The invention enables the relay station to enter a steady state.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for realizing a steady state of a relay station, a transmission system and transmission equipment. Background technique [0002] With the continuous development of communication technology, the requirement for access rate is also increasing. In order to meet the requirement of access rate, the Broadband Wireless Access (BWA) method has attracted more and more attention. The communication system established based on the IEEE802.16e standard is a kind of BWA communication system. [0003] In the 802.16e standard, wireless transmission is carried out between the base station (BS) and the subscriber station (SS). In order for the SS to send and receive data with the BS, the BS broadcasts the pilot (Preamble) and control signal at the head of each frame. order (FCH, DL-MAP and UL-MAP), and periodically broadcast the downlink channel descriptor (DCD) and uplink...
