    摘要: 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.

    摘要: Embodiments of a distributed antenna system (DAS) and method for enhanced positioning in a wireless network are generally described herein. In some embodiments, an enhanced Node-B (eNB) operates as part of a DAS that includes one or more nodes having the same cell ID as the eNB. The eNB is to transmit a UE-specific reference signal and configure one or more of the other nodes of the cell to transmit UE-specific reference signals that are distinguishable from each other and from the UE-specific reference signal that is transmitted by the eNB. The eNB may receive location estimate information from user equipment (UE) that is determined at least in part from the UE-specific reference signals. The eNB may also configure the nodes to perform cooperative OFDMA transmission techniques for the UEs operating in the cell.

    摘要: Methods and apparatus provide increased symbol length with more subcarriers in a fixed-bandwidth system. The subcarriers spacing may be reduced to provide increased symbol length and enable higher throughput. In one implementation, a system compatible with the IEEE P802.11n proposal can use 128 subcarriers in 20 MHz operation to provide increased throughput in lower-bandwidth channel operation.
