Abstract: A Device to Device (D2D) user equipment (UE) is configured to support synchronization in a D2D network. The D2D UE includes an antenna configured to communicate via a D2D communication. The D2D UE also includes processing circuitry configured to enter a communication Mode 2 when certain conditions are met. The certain conditions include: when a first timer (T310) for detecting radio link failure is running, a second timer (T311) for initiating the connection reestablishment is running, or a third timer (T301) for requesting connection reestablishment is running. In communication Mode 2, the D2D UE, on its own, selects resources from resource pool(s) to transmit D2D data and D2D control information. The processing circuitry further configured to exit the communication Mode 2 and enter a communication Mode 1 when the certain condition is no longer met. In communication Mode 1, the D2D UE uses resources configured by another station.

Abstract: Drive testing for network optimization has been supplemented by the use of information measuring radio conditions collected by mobile terminals (i.e. UEs). To improve the user experience of multicast and broadcast services based on cellular telecommunications networks, such as MBMS and eMBMS, a mechanism is described that adapts UE-based reporting of measurement reports to multicast and broadcast services.

Abstract: Methods and apparatuses for CSI reporting mechanisms are provided. A user equipment (UE) includes a transceiver and a processor operably connected to the transceiver. The transceiver is configured to receive information indicating a channel state information reference signal (CSI-RS) resource configuration, uplink-related downlink control information (DCI), and a CSI-RS associated with a selected CSI-RS resource in a same subframe as the uplink-related DCI. The processor configured to determine, in response to a CSI request included in the uplink-related DCI, an aperiodic CSI in reference to the CSI-RS. The transceiver is further configured to report the aperiodic CSI by transmitting the aperiodic CSI on an uplink channel.
