Abstract: Embodiments are presented herein of apparatuses, systems, and methods for performing unicast sidelink access stratum level connection maintenance. A first wireless device and a second wireless device may establish a unicast sidelink wireless connection. One or both of the first wireless device and the second wireless device may perform access stratum level connection maintenance on the unicast sidelink wireless connection. This may include performing any or all of radio link monitoring, radio resource management, or physical layer based link quality detection. The access stratum and the non-access stratum of each device may also communicate with each other regarding either or both of link quality or link status of the unicast sidelink wireless connection.

Abstract: First user equipment (UE) exchanges at least a portion of data to be transmitted to a communication network with a second UE on a side channel. The UEs then send the data to the network at increased transmission power by using transmit antennas of both the first and second UEs, instead of just those of the first UE. In some cases, the second UE may transmit a variation of the data sent by the first UE to perform transmit diversity and improve signal-to-noise ratio. To avoid unintended beamforming of the transmissions, the network may mix signals (e.g., having a same symbol) received at the same time period but at different sub-carriers, or mix the signals received at different time periods but at the same sub-carrier. The network may notify the UEs of a phase correction value based on the signals, and the UEs may adjust using the phase correction value.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for mitigation of secondary cell failures. A user equipment (UE) may establish communication with a macro cellular base station. The UE may perform a signal quality measurement of a small cell base station and compare the signal quality measurement to a threshold. Based on the signal quality measurement exceeding the threshold, the UE may attempt to additionally connect to the small cell base station. In response to a radio link failure of the second base station, the UE may modify the first threshold. In response to subsequent failures to additionally connect to the small cell base station using the modified first threshold, the UE may disable connections to the small cell base station.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for network assisted side-link resource configuration for unicast and/or multi-cast/groupcast communications in V2X networks. A UE may, after establishing an RRC connection with a base station, transmit, to the base station, V2X connection information. The V2X connection information may include a V2X identifier associated with the UE and a V2X identifier associated with a target UE. The UE may receive, from the base station, a side-link configuration for data transmission with the target UE. The side-link configuration may include a resource allocation defined in time and frequency (e.g., a transmit/receive pool). The UE may communicate with the target UE using the resource allocation included in the side-link configuration.
