    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 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 system and method for D2D discovery is provided. In an embodiment the method includes sending, by a base station, first parameters to a first User Equipment (UE) indicating a set of discovery resources in a discovery cycle, wherein the discovery cycle comprises a plurality of subframes; and sending, by the base station, second parameters to the first UE indicating a first probability for transmitting a first discovery signal to a second UE on a subframe of the plurality of subframes so that the first UE is capable of transmitting the first discovery signal to a second UE in the discovery cycle according to the first parameters when a random number between 0 and 1, selected by the first UE, is equal or larger than the first probability.

    Abstract: Systems and methods for User Equipment (UE) synchronization for Device-to-Device (D2D) out-of-coverage communication are provided. In an embodiment, a method in an in-coverage (IC) UE for the IC UE to become a synchronization source for out-of-coverage UEs for D2D communication includes obtaining, by the IC UE scanning parameters; scanning, by the IC UE, for out-of-coverage synchronization signals; transmitting, by the IC UE, a measurement report to a Transmission Point (TP) in response to a report trigger, the measurement report comprising information of one or more received out-of-coverage synchronization signals; receiving, by the IC UE, a configuration command from the TP instructing the IC UE to become a synchronization source in response to a configuration command from the TP; and transmitting, by the IC UE, a D2D synchronization signal (SS) for a duration of time or until instructed not to do so by the TP.
