Abstract: The present disclosure provides for the trigger of a beam refinement reference signal (BRRS) message. Triggering a BRRS message can include determining that a measured quality of a transmit and receive (Tx-Rx) beam pair is below the first value of the first quality threshold, the Tx-Rx beam pair corresponding to a current transmit (Tx) beam from an evolved node B (eNodeB) and the current receive (Rx) beam at the user equipment (UE), encoding a message for the eNodeB based on the determination that the quality of the Tx-Rx beam pair is below the quality threshold, wherein the message comprises a request for one or more BRRS, and processing the one or more BRRS to select a different Rx beam at the UE than the current Rx beam.

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.

In some embodiments, UCI symbols are mapped to resource elements (REs) in the time/frequency resource grid to maximize frequency diversity. In some embodiments, UCI is mapped in a manner that takes into account channel estimation performance by mapping UCI symbols to those REs that are closest (in terms of OFDM subcarriers/symbols) to REs that carry reference signals.

Abstract: Methods, systems, and devices for transmission and reception of SPS communications are disclosed herein. User equipment (UE) is configured to receive, in a first subframe, a physical downlink control channel or enhanced physical downlink control channel (PDCCH/EPDCCH) corresponding to semi-persistent scheduling (SPS) activation. The PDCCH/EPDCCH conveys a value of nSCID. The UE configures, based on the SPS activation, a downlink (DL) assignment in a second subframe for receiving an SPS physical downlink shared channel (PDSCH) without a corresponding PDCCH/EPDCCH. The UE determines a reference signal sequence corresponding to the SPS PDSCH using nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UE receives the SPS PDSCH in a second subframe. The UE processes the SPS PDSCH based on the reference signal sequence for the SPS PDSCH in the second subframe using the nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation.

Abstract: Devices and methods of receiving a PDCCH-less xSIB are generally described. A UE receive a xPBCH that occurs in a 0th or a 25th subframe and an ePBCH in an ePBCH transmission block. The ePBCH has the xSIB and is received on different Tx beams. The ePBCH spans consecutive symbols on the same subcarrier and with the same ePBCH symbol. The frame number, subframe number and symbol number of the ePBCH is dependent on a subframe number and symbol number of the xPBCH. The number of beams received for a particular symbol is dependent on a total number of beams, a beam sweeping time for the beams and a transmission periodicity of the xPBCH and ePBCH. The UE also uses different OCCs to demodulate a DMRS from different APs, in a same PRB as the ePBCH.

Abstract: A method for low overhead system information acquisition (LOSIA) is disclosed. The LOSIA method includes several techniques for transmitting common channels in a next generation Radio Access Technology (xRAT). Instead of transmitting system information in a periodic, static, cell-specific, wideband manner, the transmission is triggered by user equipment in an “on demand” manner. The LOSIA method allows the network to control the overhead, bandwidth, and periodicity, as well as other characteristics. The LOSIA method employs several different techniques to trigger the information upon which the network can act, for example, by transmitting different payloads depending on the received trigger.

Abstract: An eNB (or other base station) comprising one or more processors may generate a plurality of channel status activation indicators. The eNB's processors may encode the plurality of indicators into a Downlink Control Information (DCI) codeword, may scramble the cyclic redundancy check bits of the DCI with a predetermined sequence, and may generate the DCI codeword to the UE as part of a DCI transmission on a physical control channel. A UE (or other mobile handset) comprising one or more processors may process a DCI transmission from the eNB, the DCI transmission including a DCI codeword. The UE's processors may decode a plurality of channel status activation indicators from the DCI codeword, may check if the cyclic redundancy bits of the DCI are scrambled with a predetermined sequence, and may trigger a plurality of physical layer activation-and-deactivation circuitries based on the plurality of channel status activation indicators.

Cross-RAT/partition-scheduling can include when S-RAT is scheduled by P-RAT or when P-RAT is scheduled by S-RAT.

The one or more processors of the UE may then be further to process the partition configuration transmission.
