Embodiment Construction

[0015] The system and method for exchanging wireless relay scheduling information according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the embodiments described herein with reference to the accompanying drawings are merely illustrative, and the invention should not be construed as being limited to the embodiments described herein.

[0016] figure 2 is a schematic diagram showing the structure of a scheduling information exchange system for wireless relay stations according to an embodiment of the present invention. Such as figure 2 As shown, the system includes a base station and three relay stations RS1, RS2 and RS3 located in the cell of the base station. The relay stations RS1, RS2 and RS3 each have their own relay range. The base station can control all assumptions. In this system, the user equipment (not shown) has moved out of the effective range of the base ...

Abstract

The invention provides a resource scheduling method for wireless relay stations, which comprises that: a base station selects the wireless relay station with the poorest channel state from n wireless relay stations according to state information, performs exclusive OR processing on the scheduling information of the selected wireless relay station and the scheduling information of the other n-1 wireless relay stations to obtain n-1 pieces of exclusive OR data during each time slot respectively, and broadcasts the n-1 pieces of exclusive OR data to the n wireless relay stations, wherein n is an integer more than or equal to 2; and the n wireless relay stations receive the n-1 pieces of exclusive OR data during each time slot, and obtain the scheduling information of the other wireless relay station by the n-1 pieces of exclusive OR data and own scheduling information.

Description

technical field [0001] The present invention relates to resource scheduling of wireless relays, more specifically, to a method for exchanging resource scheduling information of wireless relay stations in wireless communication. Background technique [0002] In a wireless communication system, when the distance from the base station (BS) to the user equipment (UE) is long, and there are obstacles between the base station and the user equipment, sometimes a good received power cannot be guaranteed. In this case, communication quality deteriorates. To solve this problem, in the existing wireless communication system, a relay station (RS) is used to receive, amplify or decode the signal sent by the base station, and then resend it to the user equipment. [0003] In the existing wireless relay system, when the user equipment leaves the range of the base station, the base station communicates with the user equipment through the relay station. That is to say, when the base statio...
