Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform multiple TTI PUSCH transmissions in a wireless communication system as well as code block groups (CBGs) based retransmissions operations. A UE may perform radio resource control (RRC) signaling with a network entity to configure a data structure that may include one or more sets of physical uplink shared channel (PUSCH) transmission configurations, where each set of PUSCH transmission configurations span multiple TTIs. The wireless device may be configured to receive, from the network entity, a downlink control information (DCI) message that may include a time domain resource assignment field (TDRA) that may indicate a set of PUSCH transmission configurations included in the data structure. The wireless device may perform PUSCH transmissions spanning multiple TTIs according to the indicated set of PUSCH transmission configurations over an unlicensed band.

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.

Abstract: This disclosure relates to performing detection of burst cellular communication in unlicensed spectrum. A wireless device may establish a cellular link with a cellular base station, which may provide a first cell deployed on an unlicensed frequency channel. The wireless device may receive a transmission from a second cell. The second cell may not be a serving cell of the wireless device. The transmission may be received on at least a portion of the unlicensed frequency channel. The wireless device may decode a channel occupancy time field of the transmission from the second cell. The wireless device may determine a channel occupancy time of the transmission from the second cell based at least in part on the channel occupancy time field.

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.

Abstract: Apparatuses, systems, and methods for a wireless device to perform user equipment (UE) initiated beam management procedures with a base station or gNB. A wireless device in communication with a 5G base station may detect degradation in the pair of transmit and receive beams between the gNB and the device. The device may select a preferred beam management procedure and indicate the preference to the gNB.

Abstract: Apparatuses, systems, and methods for a wireless device to perform a method including performing one or more of periodic beam quality measurements and/or event based beam quality measurements, determining, based at least in part on one or more of the periodic beam quality measurements and/or the event based beam quality measurements, a recommended beam quality measurement configuration, and transmitting, to a base station serving the UE, the recommended beam quality measurement configuration. In addition, the UE may perform receiving, from the base station, instructions regarding the beam quality measurement configuration. The instructions may include instructions to activate, deactivate, and/or modify at least one beam quality measurement configuration. In addition, the instructions may be based, at least in part, on the recommended beam quality measurement configuration.

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.

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. DCI in which the GC-PDCCH/PDCCH beam indication has changed) may be increased, the transmission of such select DCI may be limited to a certain (specified) aggregation level, and in case discontinuous transmission (DTX) is received, the base station may transmit both old and new beam/QCL indications.
