    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: Embodiments of the present disclosure describe devices, methods, computer-readable media, and systems configurations for configuration of downlink coordinated multipoint (CoMP) communications in a wireless communication network. A user equipment (UE) may receive, from an evolved Node B (eNB), a radio resource control (RRC) transmission including channel state informations (CSI) reference signal (RS) parameters for a plurality of transmission points. The UE may subsequently receive a medium access control (MAC) control element (CE) including a plurality of index bits corresponding to one or more activated transmission points of the plurality of transmission points for which the feedback module is to generate CSI-RS feedback. The eNB may dynamically update the transmission points that are activated for CSI-RS feedback. The UE may receive another MAC CE from the eNB to notify the UE of the updated set of activated transmission points.

A user equipment (UE) may receive channel state information (CSI) reference signal (RS) parameters, from an evolved Node B (eNB), for individual transmission points of a coordinated multi-point (CoMP) Measurement Set including a plurality of transmission points. The UE may generate CSI-RS feedback information for the individual transmission points of the CoMP Measurement Set, and may transmit the generated CSI-RS feedback information for one or more of the individual transmission points to the eNB. The UE may receive a transmission from the eNB updating the individual transmission points included in the CoMP Measurement Set.

    摘要: A system and method for multicast servicing in a unicast subframe is disclosed. The method using an evolved Node B (eNodeB) comprises the operation of setting up a multicast service on each of a plurality of user equipments (UEs) in a multicast group using a multicast identifier. The operation of allocating unicast data channel resources for the multicast group using unicast control channel information coded by the multicast identifier follows. The method using a UE comprises the operation of receiving a multicast identifier for a multicast group from an eNodeB, wherein the multicast identifier is shared among a plurality of UEs in the multicast group. The operation of receiving unicast control channel information coded by the multicast identifier from the eNodeB follows. The next operation of the method is extracting control channel information for allocating unicast data channel resources from the received unicast control channel information using the multicast identifier.
