Problems solved by technology

[0010] (2) Waste of resources. When the traffic volume of the relay link is small and a small bandwidth is required, if the original support for the Relay frame structure is adopted, the bandwidth of the entire Relay zone needs to be allocated to the relay link. It is a huge waste of resources

Abstract

The invention provides a wireless communication system for supporting Relay characterized as comprising: base station, relay and terminal; wherein time slot of subframe is divided into uplink signal area and downlink signal area when base station and relay transmits data; the uplink signal area at least comprises uplink mixing zone, and downlink signal area at least comprises downlink mixing zone; relay receives broadcasting information, data and control signal transmitted by base station at downlink signal area; base station separately transmits data to terminal and relay at downlink direction; terminal transmit data to relay at uplink direction, and the relay receives and processes data and transmits the data to base station according to frequency resource allocated by base station; Themethod fully utilizes time frequency resource of system, reduces cost of system and promotes resource utilization.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless communication system supporting Relay. Background technique [0002] In 3G and B3G (Beyond 3 Generation, super 3 generation) communication systems, the coverage is an important indicator of the wireless access system, and the wireless access system generally achieves coverage of the service area through base stations or access points. However, due to the mobility of the terminal, it is entirely possible that the terminal is outside the service area and thus cannot obtain wireless access services; even if the terminal is within the service area, the signal transmission may still be blocked by obstacles on the transmission path, resulting in A decline in the quality of service. In the future mobile communication system, it is necessary to transmit very high-speed data (such as 1Gbps), and due to the limitation of frequency band allocation conditions, the ...
