Embodiment Construction

[0025] The present invention will now be described with reference to the drawings, wherein like reference numerals designate like or similar devices throughout.

[0026] Figures 1A and 1B describe basic IEEE802.16 relay scenarios and have been described in the background art.

[0027] According to the present invention, in the IEEE802.16 relay scenario, that is, the throughput-enhanced scenario shown in FIG. 1A and / or the coverage-extended scenario shown in FIG. 1B , all control and scheduling functions can be performed by the base station. The base station is responsible for allocating bandwidth resources for the uplink and downlink services of the relay station and wireless communication terminals as users (such as each mobile station), and coordinating the communication between the relay station and each mobile station. This centralized control method can greatly reduce the complexity and cost of the relay station. Since there is a line-of-sight transmission channel betwee...

Abstract

The invention provides a relay method in the wireless switch system which includes following steps: receiving the descending data from the base station; and the descending data includes the control information for the relay operation; building the resending ascending data; according to the configuration of control information resends the descending data, on the ascending direction, according to the configuration of control information receives the ascending data from the wireless communication terminals; recovering the ascending data in the wireless communication terminal; and resending the ascending data to said base station according to the configuration in the control information. The invention also provides base station, relay device and wireless relay system. By the invention, the base station can control the several wireless relay systems concentrately, and it can reduce the complexity of relay device, and realize the transparent transmission for the wireless communication terminals.

Description

technical field [0001] The present invention generally relates to a wireless access system, and more specifically relates to a service relay method of the wireless access system, a base station, a relay device and a relay system using the method. Background technique [0002] Since the 1990s, with the increasing demand for wireless access, especially broadband wireless access, broadband wireless access technology has developed rapidly. The Institute of Electrical and Electronics Engineers (IEEE) established the IEEE 802.16 working group to study technical specifications of broadband fixed wireless access, with the goal of establishing a global unified broadband wireless access standard. In order to facilitate the achievement of this goal, several world-renowned companies also initiated the establishment of the Worldwide Interoperability for Microwave Access (WiMAX) Forum, striving to promote this standard globally. [0003] As a next-generation wireless broadband access tec...
