Abstract: Techniques related to physical uplink control channel procedures are described. Briefly, in accordance with one embodiment, an Uplink Control Information (UCI) payload size is determined based at least in part on configuration information and Downlink Control Information (DCI). A Fifth Generation (5G) Physical Uplink Control Channel (xPUCCH) format is then determined based at least in part on the determined UCI payload size. Other embodiments are also disclosed and claimed.

Abstract: Devices for and methods of providing low latency 5G FDD communications are generally described. A HARQ ACK/NACK for an xPDSCH is transmitted in the xPUCCH of the same or next subframe as the xPDSCH and xPDCCH. An xPUSCH is generated in the same subframe in response to an xPDCCH and HARQ ACK/NACK response is carried by another xPDCCH or xPHICH in the same or next sub frame. The xPDCCH and the xPUCCH are at opposite ends of the same subframe, DL and UL subframe are delayed relative to each other, or at least one of the DL and UL subframe has an additional blank portion, portion with data associated with another UE or portion that contains a reference signal, broadcast signal or control information.

Abstract: Systems, methods, and baseband processors are provided to generate or process symbols in a synchronization subframe. In one example, a method includes selecting non-consecutive orthogonal frequency division multiplexing (OFDM) symbols in a synchronization subframe. A transmitter is instructed to transmit demodulation reference symbols (DM-RS) on identical first sets of subcarriers in respective OFDM symbols of the selected non-consecutive OFDM symbols for a Physical Broadcast Channel (PBCH) using a same transmit beam, wherein a gap between two subcarriers in a respective set of the identical first sets of subcarriers is three subcarriers. The transmitter is instructed to transmit the PBCH on identical second sets of subcarriers in respective OFDM symbols in the selected non-consecutive OFDM symbols.

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.
