MULTI-POINT TRANSMISSION IN WIRELESS COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To provide a multi-point transmission in wireless communication.SOLUTION: The embodiments are intended for wireless transmitting/receiving unit (WTRU) transmissions of different types of uplink channels and/or signals in a system deployment where multiple destination points may exist. Some embodiments are arranged so that a WTRU may dynamically select the destination point of transmission. In one or more systems where destination point selection from among multiple potential destination points may be possible for WTRU transmission, some embodiments are intended to determine a handling of hybrid automatic repeat request (HARQ) retransmissions and for different power headroom reporting mechanisms. The embodiments are also intended for the reduction and/or inhibition of WTRU transmissions to destination points to which the WTRU may have lost connectivity.SELECTED DRAWING: Figure 3
