    Abstract: A system and method for enhanced cell detection by a User Equipment (UE) is provided. The UE includes a transceiver configured to receive a discovery reference signal (DRS) occasion from at least one transmission point. The DRS occasion comprising a set of consecutive DRS sub-frames. The UE also includes processing circuitry configured to: in response to detecting a physical cell identity (PCID) of a Primary Synchronization Signal (PSS)/Secondary Synchronization Signal (SSS)/Cell-Specific Reference Signal (CRS) that is the same as a reference PCID for a configured Channel State Information-Reference Signal (CSI-RS) resource, the processing circuitry attempts to detect or measure the CSI-RS using the timing obtained from the PSS/SSS/CRS; and in response to not detecting a PCID of PSS/SSS/CRS that is the same as the reference PCID for a configured CSI-RS resource (TP), the processing circuitry does not attempt to detect or measure the CSI-RS.

    Abstract: Coordinate multi-point (CoMP) transmission is facilitated by resolving collisions between feedback reporting. Based upon the conditions within the network, collision resolution may be by dropping a channel report during a subframe, multiplexing channel reports from a plurality of user equipment, compressing channel reports a plurality of user equipment, and combined reporting, either through joint reports or by using carrier aggregation, for conditions between a user equipment and a plurality of transmission points. New signaling and reporting formats facilitate selection of a collision resolution suitable for current network conditions.

    Abstract: A method for efficient data transmission in a wireless communication system includes dynamically configuring at least one period cycle (P-CYCLE) pattern comprising a period-on (P-ON) duration and a period-off (P-OFF) duration that are adjusted in accordance with a number of transmissions from user equipments (UEs) operating in a shared band spectrum, wherein the number of transmissions comprises a number of successful transmissions or a number of unsuccessful transmissions received from the UEs. The method further includes transmitting the P-CYCLE pattern including the P-ON duration and the P-OFF duration to the UEs using a downlink channel over the shared spectrum band, wherein the downlink channel comprises a higher layer signal or a physical layer signal.
