MULTIPOINT TRANSMISSION IN WIRELESS COMMUNICATION

摘要

Embodiments contemplate wireless transmit/receive unit (WTRU) transmissions of different types of uplink channels and/or signals in a system deployment where multiple destination points may exist. Some embodiments contemplate that a WTRU may select the destination point of a transmission on a dynamic basis. In one or more systems where destination point selection from among multiple potential destination points may be possible for a WTRU transmission, some embodiments contemplate the determination of the handling of hybrid automatic repeat request (HARQ) retransmissions and for different power headroom reporting mechanisms. Embodiments also contemplate the reduction and/or inhibition of WTRU transmissions to destination points to which the WTRU may have lost connectivity.

1. A wireless transmit/receive unit (WTRU), comprising:
a processor, the processor configured, at least, to:
select at least one Uplink Transmission Context (UTC), the at least one UTC corresponding to one or more characteristics and to at least one reception point;select at least one of the one or more characteristics; andinitiate a transmission to the at least one reception point based, at least, on the at least one of the one or more characteristics, wherein the selecting of at least one of: the at least one UTC or the at least one of the one or more characteristics is done dynamically.
