Abstract: A method of determining reference signal received power (RSRP) by user equipment (UE) associated with a distributed antenna system (DAS) may include detecting at least three different reference signals in one or more common reference signals (CRSs) that are associated with different antennas in the DAS. The method may also include determining at least three different RSRPs corresponding to the at least three different reference signals. The at least three different RSRPs may be level 3 filtered to produce at least three corresponding filtered powers. The UE may report a maximum of the at least three corresponding filtered powers to the distributed antenna system.

Abstract: A system and method for multiplexing subchannels in an OFDMA network is provided. The subchannels can be multiplexed by splitting the subchannels in the frequency domain. Alternatively, the subchannels can be code division multiplexed using N orthogonal spreading codes. The subchannel multiplexing increases system capacity for low-rate services, such as voice-based services.

Abstract: 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.

Abstract: Systems and methods for providing opportunistic carrier aggregation to short range or low power extension carriers are generally disclosed herein. One embodiment includes data traffic offload techniques to offload data communicated in a Wireless Wide Area Network (WWAN) from a primary cell to a secondary cell. For example, the primary cell may be provided by a LTE/LTE-A base station operating in licensed spectrum, and the secondary cell may be provided by a low-power extension carrier operating in unlicensed spectrum using a LTE/LTE-A standard. The low-power extension carrier may be activated as needed to offload data transfers from the primary cell, in download-only, upload-only, and time-division LTE (TD-LTE) modes. Configurations involving multimode base stations, multimode user equipment (UE), relay extension carriers, and remote radio equipment are also described herein, in conjunction with deployment of opportunistic carrier aggregation using extension carriers.
