摘要:
A wireless communication method and apparatus are disclosed for assigning different phases, (i.e., time periods), to perform data transmissions over designated frequency bands in a cooperative relaying system. In phase 1, a relay station (RS) listens to a wireless transmit/receive unit (WTRU) and successfully receives b information bits. In phase 2, the RS and WTRU cooperatively transmit these b information bits to the destination. These transmissions may be performed in a unicast scheme, wherein a WTRU sends information to a selected RS in phase 1, and the RS forwards the information to a base station (BS) in phase 2. The transmission may also be performed in a multicast scheme, wherein the WTRU sends information to the RS and the BS in phase 1, and the RS transmits a subset the information to the BS in phase 2.

公开了一种用于分配不同相位(即,时间段)以在协作中继系统中在指定频带上执行数据传输的无线通信方法和装置。 在阶段1中,中继站(RS)监听无线发射/接收单元(WTRU)并成功地接收b个信息比特。 在阶段2中,RS和WTRU协调地将这些b信息比特传送到目的地。 这些传输可以在单播方案中执行,其中WTRU在阶段1中向所选择的RS发送信息,并且RS将信息转发到阶段2中的基站(BS)。传输也可以以多播方案 ,其中WTRU在阶段1中向RS和BS发送信息,并且RS在阶段2中将信息发送到BS。
