Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine to use multi-cluster communications in a vehicle based communication network. The UE may identify a configuration parameter associated with the multi-cluster communications. The UE may select a cluster resource from a set of available cluster resources based on the configuration parameter. The cluster resource may include one or more clusters used for multi-cluster transmissions in the vehicle based communication network. The UE may transmit an indication of the selected cluster resource to a wireless node of the vehicle based communication network, for example, to another UE. The UE may transmit the multi-cluster transmission on the selected cluster resource.

Abstract: Methods, systems, and devices are described for switching a mode of operations in device to device (D2D) communications. A UE within the coverage area of a base station may communicate directly with other UEs using a centralized transmission resource schedule. Prior to experiencing radio link failure (RLF), the UE may determine that switching parameters have been met and transition to an intermediate mode based on a distributed transmission schedule using a pool of resources established by the base station. In one example, the switching parameters may be received from the base station in a connection response message. In another example, the UE may send a switching request to the base station prior to initiating the transition to the intermediate mode. In some cases, after the transition to the intermediate mode, the UE may experience a radio link failure and transition to a distributed mode using a predetermined pool of resources.

Abstract: An efficient approach for a mobile device apparatus that is out of network coverage to communicate with the network is desired. The apparatus may be a user equipment (UE). The apparatus receives one or more device-to-device (D2D) signals respectively from one or more proximate UEs. The apparatus measures signal strength of the one or more D2D signals based on signal strength of one or more resource elements used for receiving one and/or more reference signals of the one or more D2D signals or signal strength of one or more resource elements used for receiving one or more data parts of the one or more D2D signals. The apparatus selects one of the one or more proximate UEs as a relay UE based on the measurement of the signal strength of the one or more D2D signals, to communicate with the base station via the selected relay UE.

Abstract: Methods, systems, and devices are describe for signaling protocols for device-to-device discovery operations in a wireless communication system. A user equipment (UE) may be communicating with a serving base station using a first frequency in a first frequency band. The UE may transmit, to the serving base station, information associated with performing a discovery scan procedure on a second frequency in a second frequency band during a discovery scan interval. The first frequency may be different from the second frequency. The UE may identify a capability to skip one or more downlink transmissions from the serving base station during the discovery scan interval.

Abstract: Techniques for scheduling assignment (SA) transmissions in device-to-device (D2D) communications are described. A D2D user equipment (UE) may use a block of time resources for SA transmissions. A D2D UE may transmit an SA transmission relatively quickly after determining that D2D data is to be transmitted to another D2D UE, relative to having to wait for specified time resources to send an SA transmission. The D2D data may then be transmitted following the SA transmission, reducing latency for transmission of the D2D data. It may be desirable for vehicle-to-vehicle (V2V) transmissions to have a relatively low latency to provide data from one vehicle to another with sufficient time for a vehicle to take action while moving at relatively high rates of speed.

Abstract: Methods, systems, and devices are described for transmissions and retransmissions of scheduling assignment (SA) information, and for content of SA transmissions. SAs may be transmitted during an initial communications period, followed by data transmissions for a certain time period. A device may monitor for transmissions during the SA period and then monitor for data transmissions during periods indicated in a received SA. SAs may be retransmitted according to a retransmission pattern that may provide time or frequency diversity patterns in order to enhance reception of SAs at a receiving device. Retransmission patterns may be determined based on a resource from an SA resource pool that is used for an initial transmission of the SA.

Abstract: Apparatuses, systems, and devices are described for transmissions and retransmissions of device-to-device (D2D) communications. A D2D message may be transmitted during an initial communications period, followed by one or more retransmissions. A device may transmit an initial transmission, determine a time hopping pattern for the retransmission(s), and determine a transmission resource for the retransmission(s) based at least in part on a resource of the initial transmission and the time hopping pattern. The messages may include, for example, a scheduling assignment (SA) for data transmission, or data transmissions from a transmitting device. Time hopping patterns may be determined based on times and/or frequencies of the initial transmission. A base station may transmit a message to a transmitting device that indicates one or more time hopping patterns that are to be used for the transmissions.
