Abstract: Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for a UE to request a beam quality measurement procedure. A user equipment device may be configured to perform a method including performing transmitting a request to perform a beam quality measurement procedure for downlink receptions (e.g., a P3 procedure) to a base station/network entity, receiving instructions to perform the beam quality measurement procedure from the base station, and transmitting results of the beam quality measurement procedure to the base station. In some embodiments, transmission of the request may be response to at least one trigger condition and/or detection of a condition at the UE. The request may include an indication of a preferred timing offset. The instructions to perform the beam quality measurement procedure may include a schedule for the beam quality measurement.

Abstract: A device, system and method for determining when to initiate certain operations associated with received data. The method is performed at a device connected to a network. The method includes estimating a first number of repetitions of a subframe which is associated with a likelihood that the device will successfully perform an operation based on the subframe. The method further includes delaying initiating the operation for the subframe until a received number of repetitions of the subframe is greater than or equal to the first number of repetitions.

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: Apparatuses, systems, and methods to dynamically indicate preference for self-contained slots and slot duration by a user equipment device (UE) in communication with a base station (e.g., a gNB) using a 5G NR radio access technology. A UE may determine to send an indication to a gNB indicating a preference for self-contained slots and slot duration for downlink and/or uplink communications utilizing one or more of the physical downlink control channel (PDCCH), the physical downlink shared channel (PDSCH), and/or acknowledgement messaging (ACK/NACK) for downlink communications, and utilizing one or more of the physical uplink control channel (PUCCH), the PDCCH, and/or the physical uplink shared channel (PUSCH) for uplink communications. The configuration of self-contained slots and slot duration for uplink and/or downlink may be based on one or more of average packet size, average packet rate, traffic type and UE processing capabilities.

Abstract: Adaptive multiplexing and transmit/receive diversity. A wireless device may include multiple antennas. A first set of antennas may be used for communication. One or more trigger conditions may be determined, and additional antennas may be activated for measurement. Based on the measurement(s), a second set of antennas may be selected and used for communication.

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.

Abstract: This disclosure relates to techniques for estimating baseband power consumption and using the baseband power consumption estimation to select baseband operation features. According to some embodiments, one or more baseband power consumption modifiers occurring during an estimation window may be identified. Baseband power consumption of the wireless device during the estimation window may be estimated based on the identified baseband power consumption modifiers occurring during the estimation window. Baseband data throughput of the wireless device during the estimation window may also be estimated. One or more baseband operation characteristics may be selected based at least in part on the estimated baseband power consumption during the estimation window, possibly in conjunction with the estimated baseband data throughput during the estimation window, current wireless medium conditions, and/or other considerations.

Abstract: In order to facilitate communication in a dynamic cellular network, an accessibility issue in the dynamic cellular network may be detected. For example, if an electronic device is near the boundary between two adjacent cells in the dynamic cellular-telephone network, the signal power of signals from the adjacent cell may be higher than that of signals from the current servicing cell, which may offer an opportunity to improve communication performance. Thus, the accessibility issue may be detected if the difference is larger than a threshold value (such as 2-4 dB). In response to detecting the accessibility issue, a remedial action may be performed, such as repeating at least a portion of an acquisition process. In this way, the communication technique may improve the communication performance of the electronic device in the dynamic cellular network, thereby improving the user experience and customer satisfaction.
