Abstract: A wireless communication device (UE) may provide information pertaining to one or more operating capabilities of the UE to LTE and 5G-NR networks. The UE may transmit information to an LTE base station directly, and to a 5G-NR base station directly, or indirectly via the LTE base station. The information may include preferred values corresponding to any number of different operating parameters associated with wireless communications or wireless communication capabilities of the UE in both LTE and 5G-NR networks, to inform and/or request the LTE and 5G-NR networks to make provisions based on the transmitted information for the wireless communications of the UE on those networks. The UE may thereby provide assistance information to LTE and 5G-NR networks in a multi-radio-access-technology dual-connectivity setting to request the respective networks to adjust certain operating capabilities of the UE in order to alleviate one or more operating issues that may be affecting the UE.

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: Apparatuses, systems, and methods for a user equipment device (UE) to perform a method using a status change of a timer associated with a connected mode discontinuous reception (CDRX) communication session with a base station to trigger a switch from using a first bandwidth part (BWP) to a second BWP as the active BWP for the CDRX communication session. The timer may be an on-duration timer, an inactivity timer, or a retransmission timer. The UE may also alter a monitoring schedule of a physical downlink control channel (PDCCH) in response to detecting the status change of the timer. The second BWP may have a wider or narrower bandwidth than the first BWP, depending on the type of timer and the type of status change.

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: A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.

Abstract: An evolved Node B (eNB) serves as a primary serving cell (PCell) providing a primary component carrier (PCC) in a licensed spectrum to a user equipment (UE) in a carrier aggregation (CA) scheme. A secondary component carrier (SCC) is provided in an unlicensed spectrum. The eNB monitors parameters of bandwidths in the unlicensed spectrum, when at least one of the parameters indicates a change in availability of a select one of the bandwidths, the eNB generates a control indicator defining the change in availability of the bandwidth and broadcasts the control indicator to the UE, wherein the control indicator affects a modification in a transceiver of the UE associated with the bandwidth.

Abstract: Methods and devices for performing an offline beam search. The methods include receiving a radio frequency signal comprising a reference signal, wherein the radio frequency signal corresponds to a transmitter beam, projecting the radio frequency signal on orthogonal signal subspaces and storing the projected signals and performing a beam search to identify a receiver beam for the transmitter beam using the projected signals, wherein the beam search is performed offline.

Abstract: This disclosure relates to techniques for opportunistically depowering receiver chains of a wireless device. Based on received control information, a device may determine a depowering time. For example, the device may determine a minimum number of symbols of the payload channel that will provide an effective spectral efficiency less than a supportable spectral efficiency of the payload channel. The depowering time may be determined as a time upon receipt of the determined minimum number of symbols. The device may determine whether to perform a depowering procedure, based upon the determined depowering time. In response to determining to perform the depowering procedure, the device may depower an RF receiver of the device at the depowering time, wherein the depowering time is prior to the end of the payload channel. The device may decode the payload channel based on a portion of the payload channel received by the RF receiver.

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.
