Abstract: Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE) comprises circuitry to configure a scheduling request (SR) transmission based on a physical uplink control channel (PUCCH), and combine the scheduling request with a buffer status report (BSR). The UE transmits the combined SR and BSR in a single subframe to a network entity, receives uplink resource scheduling from the network entity in reply to the combined SR and BSR, and transmits uplink data to the network entity according to the uplink resource scheduling.

Abstract: Techniques for facilitating device-to-device (D2D) communications using a high efficiency distributed channel access scheme are generally described herein. In some examples, a communication zone allocated for wireless D2D communications is divided into resource contention and scheduled transmission portions. The resource contention segment may be used to transmit a request message from a transmitting device to a receiving device (a request-to-send message), and transmit a response to the request message from the receiving device to the transmitting device (a clear-to-send message). The response can indicate a time for the data transmission to occur during the scheduled transmission segment. During the scheduled transmission segment, the scheduled data transmission and other D2D data transmissions among the various devices will be performed. In further examples, contention access techniques may be used during the resource contention segment to manage access to the resource channel.

Abstract: A method for selecting at least one parameter for downlink data transmission with a mobile user equipment. The method is executable by a wireless communication base station having multiple antennas configured to communicate wirelessly with the mobile user equipment. The method receives an uplink probing signal from the mobile user equipment. The method determines a plurality of angles of arrival for a corresponding plurality of paths between the mobile user equipment and the multiple antennas. The method transmits a plurality of downlink probing signals directionally toward corresponding angles of arrival in the plurality of angles of arrival. Each downlink probing signal is a virtual antenna port with respect to the mobile user equipment. The method receives channel state information. The method composes at least one of a rank indicator (RI), precoding matrix indicator (PMI), or modulating and coding scheme (MCS) for downlink data transmission to the mobile user equipment.
