Abstract: Methods, systems, and devices for wireless communications are described. A central access node (CAN) may manage and schedule resources for a wireless mesh network. The CAN may transmit a first message to a relay access node (AN) to expedite transmission of a priority communication in the wireless mesh network. The first message may provide configuration information for modifying a preconfigured schedule to expedite the transmission of the priority communication. For example, the first message may provide configuration information to modify a preconfigured schedule to allow a first network node to transmit the priority communication to a second network node during a reserved time period. The relay AN may generate a second message regarding the modified schedule and transmit the second message to the second network node.

Abstract: Systems and methods herein remedy thermal constraints experienced by wireless communication systems operating in the millimeter wave spectrum. User equipment (UE) having a plurality of antenna subarrays controlled by respective RFICs monitor temperature gradients of respective sectors of the UE. Upon the thermal gradient of a sector reaching a temperature threshold, the UE performs thermal management steps to prevent hardware of a respective sector from damage due to overshoot.

Abstract: Various aspects of the present disclosure relate to vehicle-to-vehicle (V2V) data sharing. The sensor data collected from each vehicle may be divided into common information and detailed information. The common information is broadcasted to every other nearby vehicle. Based on the received common information other vehicles may express interest in some particular detailed information. Unicast and/or multicast sessions may be set up to share the detailed information with the interested vehicles.

Abstract: Techniques for procedures using request to send/clear to send (RTS/CTS) procedures and multiple timers are described. A RTS/CTS procedure using multiple timers may use a first timer and a second timer. The first timer may be associated with a duration to transmit and receive a request to send (RTS) message and a clear to send (CTS) message. The second timer may be associated with a duration to transmit a data message. A network device may transmit a RTS message to request communication resources to transmit data. If the CTS message is not received prior to the expiration of the first timer, neighboring network devices may determine that the communication resources were not allocated and may attempt to request the newly available resources. If a CTS message is received, the network device may communicate the second timer data to the neighboring network devices in a variety of ways.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may select an orthogonal metric based at least in part on at least one of each direction of a plurality of directions to transmit millimeter wave discovery signals or a location parameter associated with the transmitting device. The transmitting device may transmit, in the each direction of the plurality of directions, the millimeter wave discovery signals, where the each transmitted millimeter wave discovery signal has a different orthogonal metric applied that was selected based at least in part on the at least one of the each direction or the location parameter.

Abstract: Methods, systems, and devices for wireless communication are described. A relay wireless node may receive, during a first transmit time interval (TTI), a data message to be forwarded to a wireless node. The relay wireless node may forward the data message to the wireless node during the first TTI. The relay wireless node may receive, during a second TTI, a feedback message from the wireless node. The relay wireless node may retransmit the feedback message during the second TTI.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless node may transmit directional signals in a sweeping transmission pattern while receiving communications from a second wireless node. Another wireless node may then, during a listen-before-talk (LBT) procedure, receive one of the directional signals, and terminate a correspondence communication session to avoid potential interference. Additionally or alternatively, a wireless node may listen in directions in a sweeping receive pattern while transmitting to a second wireless node. While listening, the wireless node may detect a transmission from a third wireless node in a particular direction. The wireless node may then accordingly refrain from transmitting in that direction to avoid potential interference.

Abstract: Methods, systems, and devices for wireless communication are described in which a number of reference signal processes may be configured for a number of slots in a radio frame, and a corresponding reference signal process for each slot may be based at least in part on a location of the slot within the radio frame and a number of configured reference signal processes. An indication may be provided to a user equipment (UE) in each slot that indicates a presence or absence of a reference signal transmission in the slot.

Abstract: Methods and apparatus related to the sharing of wide area network (WAN) with peer to peer communication signaling usage are described. A mobile communications device receives a signal from a base station and measures a power of the received signal. The mobile communication device determines a transmission power level of a peer to peer reference signal as a function of the measured power of the received signal from the base station, wherein said function of the measured power of the received signal from the base station depends on a mobile target signal to noise ratio. The mobile communications device broadcasts the peer to peer reference signal at the transmission power level.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a first base station (e.g., corresponding to, associated with, or included in a first cell) includes receiving location information from a vehicle; identifying, based at least in part on the location information, a plurality of cells from which to broadcast a location message associated with the vehicle, where the plurality of cells include at least a cell of a second base station; and communicating with at least the second base station regarding a broadcast of the location message. A method for wireless communication at a vehicle include transmitting location information from the vehicle to a base station on an access stratum (AS) layer, and transmitting location message information to the base station. Numerous other aspects are provided.
