Abstract: Aspects are described for modifying transmission of control channel signaling during wireless communication. The described aspects include detecting a communication condition corresponding to signaling information transmitted on a Dedicated Channel (DCH); determining whether a Dedicated Physical Data Channel (DPDCH) is transmitted based on detecting the communication condition; and performing a Dedicated Physical Control Channel (DPCCH) gating pattern in response to the determination that the DPDCH is not transmitted, wherein performing the DPCCH gating pattern includes intermittently transmitting the DPCCH when one or more signaling radio bearers (SRBs) are not being transmitted.

Abstract: Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, an uplink MIMO transmission (e.g., a rank 2 transmission) may be established, wherein a primary stream transport block size (TBS) is determined in accordance with a received scheduling grant, and a modulation scheme for the transmission is determined in accordance with the TBS. Further, a predetermined spreading factor, such as a 2×SF2+2×SF4 spreading factor, may be configured for both uplink streams, independent of the TBS. Finally, the uplink MIMO transmission may be made in accordance with the determined TBS, modulation scheme, and spreading factor. In some examples, if the primary stream TBS or a determined secondary stream TBS is less than a minimum threshold TBS, the transmission may be reconfigured as a rank 1 transmission.

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.
