  • Publication number: 20190313350
    Abstract: Apparatuses, systems, and methods for performing timing synchronization between a base station and a user equipment device within an unlicensed spectrum band. In some scenarios, beamforming tracking may also be performed. Upon determining that a transmission medium within the unlicensed spectrum band is available for transmission, a base station may transmit a plurality of synchronization signal blocks (SSBs), or a plurality of copies of one SSB, with associated remaining minimum system information (RMSI) blocks, within a single time instance within a SSB burst window. The SSBs may be transmitted at different frequency positions and according to distinct beamforming configurations. The SSBs and RMSI blocks may be configured such that a receiving user equipment device may determine the time-domain, and optionally the frequency-domain, position of the SSB and RMSI within the SSB burst window, to allow timing synchronization and optionally beamforming tracking.

  • Publication number: 20190313382
    Abstract: Techniques are disclosed relating to control data for retransmissions in wireless communications. In various embodiments, a UE sends acknowledgements (e.g., HARQ acknowledgements) at code block group (CBG) granularity. CBGs may be included in codewords that may be transmitted using multiple MIMO layers. In some embodiments, the network is configured to send a new data indicator for each CBG. In some embodiments, the network is configured to use a different number of layers for a retransmission of a CBG than for the original transmission. Thus, the layer-to-CBG or layer-to-codeword mapping may be specified dynamically. In various embodiments, the disclosed techniques may improve overall network bandwidth relative to traditional retransmission techniques.

  • Publication number: 20190281546
    Abstract: A base station and mobile device (UE) may coordinate transmission of reference signals and reception of corresponding channel state information (CSI) reports. If a periodic reference signal is scheduled for transmission outside the on-duration period of the UE, even if the reference signal corresponds to a periodic CSI report scheduled to be transmitted by the UE during the on-duration period, the base station may not transmit the periodic reference signal, thereby allowing the UE not to prematurely exit a low-power state. The base station may instead transmit an aperiodic reference signal at a specified point in time later than the scheduled transmission of the periodic reference signal. The UE may receive the aperiodic reference signal and either transmit the periodic CSI report or an aperiodic CSI report in response, depending on how close to the start of the on-duration period the transmission of the periodic CSI report is scheduled.

  • Publication number: 20190281652
    Abstract: Apparatuses, systems, and methods for a base station to perform a method construct dynamic hierarchical sub-configurations of bandwidth parts (BWPs) for use in a connected mode discontinuous reception (CDRX) communication session with a user equipment (UE) device. The base station may configure a first BWP at a baseband frequency associated with the CDRX communication session as a default BWP, a second BWP with a wider bandwidth than the first BWP as a transmission BWP, and one or more third BWPs as resting BWPs. The transmission BWP and the one or more resting BWPs may be configured to periodically override the default BWP as the active BWP for a predetermined number of CDRX cycles. The transmission BWP may be utilized, when activated to perform data transmission by UE device, and the one or more resting BWPs may be utilized, when activated, for performing channel measurements.

  • Publication number: 20190254120
    Abstract: A hierarchical beamforming structure may help reduce network traffic overhead for transmission of beam indication (information) and enable efficient Transmission Configuration Indication, while facilitating beam tracking between a base station(s) and a mobile device(s) during downlink communications. Downlink control information (DCI) may be expanded to carry/transmit a beam/QCL (quasi co-location) indication for a control resource set (CORESET) for monitoring a next instance of a physical control channel. Error resilient design techniques may be employed to further improve device mobility while increasing the flexibility and reducing the latency for GC-PDCCH/PDCCH beam/QCL indications. For example, the aggregation level for select DCI (e.g.

  • Publication number: 20190253137
    Abstract: Techniques are disclosed relating to handling preemptive data services in cellular wireless transmissions. In some embodiments, a device wirelessly transmits uplink data for a first data service during a time dimension duplex (TDD) scheduled transmission interval using a first frequency band. While transmitting, in these embodiments, the device also monitors a downlink control channel that uses a second frequency band that does not overlap with the first frequency band. The downlink control channel may be dedicated for preemption indicators that indicate another service is preempting scheduled resources. In response to detecting an indicator in the downlink control channel of communications for a second data service in the first frequency band during the scheduled transmission interval, the device may reduce the transmission of the uplink data on resources used for the communications for the second data service (e.g., by blanking or transmitting at a lower power).
