Embodiment Construction

[0034] In traditional single-hop systems (such as 802.16-2004 and 802.16e-2005), standard admission procedures already exist to support MS or SS to enter the communication network. However, when the network is modified to support relay functions that traditional MSs or SSs do not understand, from the network point of view, it is necessary to modify the network entry procedure in order to quickly and effectively support MS / SS network entry.

[0035] The present invention provides a protocol intended to be used as a modified entry procedure (ie in RS and BS) from a network point of view. Specifically, this protocol is designed to be able to apply the IEEE802.16 standard, and from the perspective of MS or SS, there is no need to change the program. This protocol is also designed for the case of non-transparent relays, where the RS is able to transmit preambles and broadcast control information, and thus has the ability to manage the process locally (i.e., decentralized control), ...

Abstract

The invention discloses a wireless communication system, a communication method for use in the wireless communication system and an intermediate apparatus. The system includes a source apparatus, a destination apparatus and an intermediate apparatus, where the source apparatus and destination apparatus are arranged to transmit and receive information via the intermediate apparatus, and where at least the source apparatus is arranged to perform a network entry process including the ranging process in order to connect to the system. The communication method for use in the wireless communication system includes, in the intermediate apparatus, managing the ranging process between the intermediate apparatus and the source apparatus until the threshold is met.

Description

[0001] This application is filed in accordance with Article 42 of the Detailed Rules for the Implementation of the Patent Law. It is a divisional application of a Chinese patent application with an application date of September 6, 2007, an application number of 200710149198.x, and an invention title of "communication system". technical field [0002] Currently, there is intense interest in using multi-hop techniques in packet-based radio communication systems and other communication systems, which are said to enable both extended coverage and increased system capacity (throughput). Background technique [0003] In a multi-hop communication system, communication signals are sent in a communication direction along a communication path from a source device to a destination device via one or more intermediate devices. figure 1 exemplarily includes a base station BS (known as a "node-B" NB in ​​the context of a 3G communication system), a relay node RN (also known as a relay stati...
