METHOD AND DEVICE FOR COOPERATIVE WIRELESS COMMUNICATIONS

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for cooperation in wireless communication.SOLUTION: A wireless transmitter/receiver unit (WTRU) 150 transmits channel state information (CSI) or a beam forming weight to a plurality of network nodes including a relay node (RS) 160 and a base station (BS) 195. Based on the CSI or the beam forming weight, the plurality of network nodes prepare to beam form data to perform cooperative transmission. Also, one network node BS 195 transmits scheduling permission information. Based on the scheduling permission information, the WTRU 150 receives identical data virtually simultaneously from the plurality of network nodes.SELECTED DRAWING: Figure 2
