    Abstract: A method, a computer-readable medium, and an apparatus may include a receiving UE that is configured to receive at least a portion of a message for a service group, measure a signal strength for the message received, and determine whether to send feedback based on the signal strength measured for the message. In some aspects, a transmitting UE is configured to determine an intended range for a service group, and transmit a message for the service group based, at least in part, on the intended range. In some aspects, the transmitting UE is configured to receive HARQ feedback from at least one receiving UE, measure a signal strength for the HARQ feedback, and determine whether to resend the message based on the signal strength measured for the HARQ feedback.

    Abstract: An improved manner of transmitting and receiving messages in V2X/V2V/D2D is presented in which a transmitting device determines a geographic location of the mobile transmitting device and generates a message for a service group having a group ID associated with the service group, the message comprising a first indication of a geographic area associated with the message, the geographic area based at least in part on the geographic location of the transmitting device. Then, the apparatus transmits the message to the service group, e.g., via V2X/V2V/D2D communication. A receiving device then determines its geographic location and determines whether to send a feedback for the message based on the first indication of the geographic area associated with the message and the geographic location of the receiving device.

    Abstract: A method, a computer-readable medium, and an apparatus may be a first UE in a bundled TTI comprising a first TTI and a second TTI. The first UE is configured to receive a first data transmission and a first reference signal from a second UE in the first TTI, to transmit a SRS to the second UE, and to receive a second data transmission having one or more transmission parameters adapted based on the SRS in the second TTI. In certain aspects, the first UE is configured to transmit a first data transmission and a first reference signal to a second UE in the first TTI, to receive a SRS from the second UE, to adapt one or more transmission parameters for a second data transmission in the second TTI based on the SRS, and to transmit the second data transmission to the second UE in the second TTI.

    Abstract: A method, a computer-readable medium, and an apparatus may involve wireless communication in a bundled TTI comprising a first TTI and a second TTI. A first UE may be configured to receive a first data transmission and a first reference signal from a second UE in the first TTI, to transmit a feedback to the second UE, and to receive a second data transmission having one or more transmission parameters adapted based on the feedback in the second TTI. In certain aspects, the first UE may be configured to transmit a first data transmission and a first reference signal to a second UE in the first TTI, to receive a feedback from the second UE, to adapt one or more transmission parameters for a second data transmission in the second TTI based on the feedback, and to transmit the second data transmission to the second UE in the second TTI.

    Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus communicates with a second apparatus, including transmitting or receiving a first transmission. The apparatus receives information about the second UE from a sensor at the first UE and/or from a BSM. The apparatus determines whether the first apparatus and the second apparatus are in a LOS condition based on a correlation of the information with one or more of a channel estimation, PMI feedback, or RI feedback. The apparatus may adapt a transmission parameter for a second transmission based on a predicted location of the first apparatus or the second apparatus. The transmission parameter may include at least one of a modulation, a code rate, a DMRS density, a precoder, a CSI-RS transmission periodicity or a feedback rate.

    Abstract: Various aspects are provided related to techniques for signal extension (SE) signaling. A signal extension (SE) duration for a data unit can be identified from a set of at least three possible SE durations. A single signaling bit in the data unit can be used to indicate the identified SE duration from the set of at least three possible SE durations to a receiver of the data unit. The data unit can be output for transmission to the receiver.

    Abstract: An example method may include decoding, at a UE, a downlink data transmission and determining, over each of multiple streams including a single stream and two dual streams, whether to transmit an acknowledge (ACK) or a negative acknowledge (NACK) message to a base station based on a result of the decoding. Further, the example method may include calculating a signal noise ratio (SNR) value for adjusting each of the multiple streams based on the determining. Further still, the example method may include mapping the calculated SNR value of the single stream to a first channel quality indicator (CQI) value. Moreover, the example method may include mapping the calculated SNR value of the two dual streams to a second CQI value. In addition, the example method may include transmitting the first CQI value and the second CQI value to the base station.
