Abstract: Various features described herein relate to DM-RS design for a control channel and a data channel that maybe used for vehicular communications. In an aspect, a UE may determine a base DM-RS sequence associated with a control channel for V2V communication. The UE may further determine a DM-RS sequence based on the base DM-RS sequence and an identity of the UE, and transmit a plurality of DM-RS symbols within the control channel in a subframe using the DM-RS sequence. In another aspect, a UE may generate a plurality of DM-RS sequences, each DM-RS sequence maybe generated for a corresponding DM-RS symbol of a plurality of DM-RS symbols associated with a data channel for V2V communication based on a DM-RS symbol number of the corresponding DM-RS symbol. The UE may transmit the plurality of DM-RS symbols within the data channel in a subframe using the plurality of DM- RS sequences.

Abstract: Improvements may be made for the Channel Busy Ratio, CBR, based congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a User Equipment, UE. The UE determines an energy-based channel busy ratio (CBR) based on a number of probes on a set of radio resources having respective energy levels greater than an energy threshold. The UE performs congestion control based on the energy-based CBR by adjusting at least one transmission parameter of one or more transmission parameters or transmission power of the UE based on the energy-based CBR.The adjusting may be carried out taking into account a usage limit, or CBR limit. In addition, the UE may detect that a second technology different from a first technology is also using the channel, and in addition consider a decode-based CBR for the purpose.

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: A method, an apparatus, and a computer program product for wireless communication are provided in connection with improving packet communication in a broadcast D2D communication system. In an example, a communications device is equipped to receive a first packet during a first timeslot from a broadcast transmitter, measure a power level of a NACK received during the first timeslot, receive the first packet during a second timeslot, and determine whether to transmit the first packet during the second timeslot based on the measured power level of the NACK. In such an aspect in which the communications device determines that the measured power level of the NACK is above a threshold power level, the communications device may act as a relay and transmit the first packet during the second timeslot.

Abstract: A user device may transmit a request to a base station for an allocation of device-to-device (D2D) discovery resources. In response to the request, the user device may receive from the base station a response that indicates whether the D2D discovery resources allocated to the user device are common resources (e.g. Type 1) or dedicated resources (e.g. Type 2, including two different variations: Type 2A and Type 2B).
