    Abstract: A device is configured to perform a method of wireless communication in a wireless communication network. The method includes receiving, from a communications controller, a device-to-device (D2D) subframe configuration to communicate with one or more second wireless devices, the subframe configuration indicating one or more subframes in which to transmit a D2D signal or receive one or more D2D signals. The method also includes receiving, from the communications controller, scheduling information to transmit a first signal to the communications controller on a subframe indicated by the D2D subframe configuration. The method further includes prioritizing the transmission of the first signal over a transmission of the D2D signal or a reception of the one or more D2D signals, and transmitting the first signal.

    Abstract: A next-generation base station can update an uplink-downlink (UL/DL) configuration of a cell more frequently than legacy user equipments (UEs) are configured to recognize UL/DL updates while preventing non-compliant uplink transmissions in downlink subframes. For instance, a next-generation base station can restrict updates to the uplink-downlink configuration such that uplink timeslots previously allocated for random access channel (RACH) transmission opportunities by legacy UEs remain configured for uplink transmission. Alternatively, the next-generation base station can restrict the allocation of RACH transmission opportunities of legacy UEs to timeslots that are statically configured for uplink transmission. Notably, such a restriction may be selectively applied to legacy UEs, so as to not limit the performance of next-generation UEs.

    Abstract translation: 下一代基站可以比传统用户设备（UE）更频繁地更新小区的上行链路 - 下行链路（UL / DL）配置以识别UL / DL更新，同时防止下行链路子帧中的不符合上行链路传输。 例如，下一代基站可以限制对上行链路 - 下行链路配置的更新，使得由传统UE先前分配给随机接入信道（RACH）传输机会的上行链路时隙保持配置用于上行链路传输。 或者，下一代基站可以将传统UE的RACH传输机会的分配限制为静态配置用于上行链路传输的时隙。 值得注意的是，这种限制可以选择性地应用于传统的UE，以便不限制下一代UE的性能。

    Abstract: A method for device-to-device (D2D) communication includes determining that a first user equipment (UE) is out-of-coverage, the first UE having been previously in-coverage on a first cell. The method also includes starting a timer upon determining that the first UE is out-of-coverage and determining whether the first UE has returned to be in-coverage after starting the timer. Additionally, the method includes determining whether the timer has expired and communicating, by the first UE directly with a second UE, using out-of-coverage resources from the first cell when the timer has not expired and the first UE has not returned to be in-coverage.

    Abstract: Embodiments are provided for optimizing the Almost Blank Subframe (ABS) pattern in heterogeneous network (HetNet) deployments with multiple small cells. One ABS pattern is used for all small cells. Different small cells can have different downlink loads from user equipments (UEs). An embodiment method includes transmitting a pilot signal in a small cell, and determining downlink load (DLL) information according to a pair of measurements from each UE served by the small cell. The pair of measurements includes a first measurement of the pilot signal and a second measurement of a second pilot signal from a macro cell. The method further includes determining a number of ABSs according to the DLL information, and reporting the DLL information and the number of ABSs to a network entity for selecting ABS density and range extension for the small cell and the macro cell.
