Abstract
User Equipment (UE) and methods for antenna port quasi co-location signaling in coordinated multi-point (CoMP) operations are generally described herein. In some embodiments, one or more downlink channels are at least partially offloaded from a serving Evolved Node-B (eNB) to one or more neighbor eNBs. The UE may receive signaling from the serving eNB to indicate a reference signal of a neighbor eNB to use for estimation of one or more large-scale physical-layer parameters associated with the one or more downlink channels provided by one of more of the neighbor eNB. The UE may estimate the one or more large-scale physical-layer parameters based on receipt of the indicated reference signal from the neighbor and serving eNBs. The UE may also apply the estimated one or more large-scale physical-layer parameters for processing the one or more downlink channels from the neighbor and serving eNBs.

22. User Equipment (UE) arranged to:
-
receive signaling from a serving Evolved Node B (eNB) indicating a transmission mode for receiving a downlink channel, the transmission mode indicating that a first set of antenna ports and a second set of antenna ports are quasi co-located; estimate a member of a set of large scale parameters for the first set of antenna ports, members of the set of large scale parameters including at least one of Doppler shift, Doppler spread, average delay, or delay spread; and apply the estimated member of the set of large scale parameters to operations of the second set of antenna ports based on the indication of quasi co-location between the first set of antenna ports and the second set of antenna ports. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
