摘要： A method for relaying data packets to a subscriber station (SS) by taking a relay station (RS) into consideration when a base station (BS) establishes a data packet scheduling is disclosed. According to the method, a data packet is relayed by RSs, which have a signal intensity greater than a threshold value for all RSs appointed by the BS. Each SS determines whether the SS receives the data packet directly from the BS or via an RS, based on signal intensities between the SS and the BS and between the SS and RSs, and feeds channel information corresponding to the determination back to the BS, thereby allowing the data packet to be transmitted.
摘要翻译：公开了一种通过在基站（BS）建立数据分组调度时考虑到中继站（RS）来将数据分组中继到用户站（SS）的方法。根据该方法，数据分组由RS中继，对于由BS指定的所有RS，信号强度大于阈值。每个SS基于SS和BS之间以及SS和RS之间的信号强度确定SS是直接从BS还是经由RS接收数据分组，并且将与该确定相对应的信道信息反馈给BS，从而允许传输数据包。
