Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for bandwidth part (BWP) dynamic adaptation in accordance with an energy level at a user equipment (UE). In some systems, the UE may implement techniques for power savings by operating according to a narrower BWP in accordance with an energy level at the UE. In some implementations, the UE may reduce the bandwidth size of the active BWP if the UE energy level satisfies a threshold. The UE may transmit signaling to the network indicating that the bandwidth size of the active BWP is reduced. Additionally, or alternatively, the UE may fall back to a default BWP if the UE energy level satisfies a threshold. For example, the UE may fall back to the default BWP prior to expiration of a timer configured to trigger the UE to fall back to the default BWP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a source base station associated with a source master cell group (MCG), a physical uplink shared channel (PUSCH) repetition in one or more slots of the source MCG during a handover of the UE from the source MCG to a target MCG. The UE may perform, to a target base station associated with the target MCG, an uplink transmission in one or more slots to the target MCG during the handover, wherein PUSCH repetitions associated with the source MCG that overlap in time with the uplink transmission to MCG are canceled and a counting of the PUSCH repetitions is based at least in part on slots of the source MCG associated with canceled PUSCH repetitions. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A device may receive a resource allocation for transmitting a transport block (TB) over a set of time slots. The TB may include a set of coded bits. In some aspects, the device may determine starting indexes of subsets of the coded bits, each subset of the coded bits may be for transmission during a respective subset of time slots. In some other aspects, the device may receive a configured grant for a transmission of the TB over the set of time slots. In other aspects, the device may scale a size of the TB based on a first value independent of a second value associated with a number of time slots associated with the set of time slots.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a network entity scheduling a set of multiple periodic tracking reference signals (TRSs) and indicating a transmission power level for the periodic TRSs. For example, the control signaling may be received via radio resource control (RRC). The UE may receive a downlink control information (DCI) message from the network entity indicating an adjustment to the transmission power level and a resource for an aperiodic TRS. The UE may monitor the resource for the aperiodic TRS in accordance with the indicated adjustment to the transmission power level. The UE may transmit a message to the network entity indicating a measurement of the aperiodic TRS based on the adjustment to the power level. The adjustment to the power level may apply to one or more of the set of multiple periodic TRSs.

Abstract: Aspects described herein relate to physical downlink control channel (PDCCH) limits for multiple cells scheduling one cell in fifth generation new radio (5G NR). In an example, the aspects may include determining a PDCCH limit corresponding to at least one of a number of blind detections (BDs) and a number of control channel elements (CCEs) used for decoding PDCCH candidates for a first cell that schedules a second cell, and at least a third cell that schedules the second cell, wherein the third cell is the same cell as the second cell or the third cell is different from the second cell; and receiving one or more PDCCH transmissions from the first cell and the third cell based on the PDCCH limit.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform beam sweeping for a physical uplink channel within time domain windows or across time domain windows based on a time domain window index. In cases where frequency hopping is enabled, the UE may transmit uplink repetitions and demodulation reference signals (DMRSs) across two frequency hops during two consecutive time domain windows using a first transmit beam, and may then follow up with transmissions across two frequency hops during the next two consecutive time domain windows using a second transmit beam. Or, the UE may transmit uplink repetitions and DMRSs in a first frequency hop with first and second transmit beams during two respective consecutive time domain windows, and may transmit in a second frequency hop with the first and second transmit beams during the next two respective consecutive time domain windows.

Abstract: Aspects relate to mechanisms for wireless communication devices for tone reservation. A user equipment (UE) receives an indication of one or more peak-reduction tone (PRT) resources for a transmission of one or more signals for a base station. The UE transmits a first signal to the base station on an uplink. The UE transmits a second signal to a relay entity on a sidelink for reception by the base station. The second signal is transmitted on the sidelink utilizing the one or more PRT resources.

Abstract: Methods, systems, and devices for wireless communications are described to switch between waveform configurations based on an indicated modulation coding scheme (MCS) such that waveform switching may be signaled implicitly. A base station may configure a user equipment (UE) with a hybrid MCS table including MCS indexes associated with a first waveform configuration and MCS indexes associated with a second waveform configuration. The base station may schedule resources for an uplink transmission for the UE and may indicate an MCS index associated with the uplink transmission, using index from the MCS table. The UE may select a waveform configuration for the uplink transmission based on the MCS index. For example, the UE may compare the MCS index with a threshold MCS index of the hybrid MCS table and determine a waveform configuration associated with the MCS index based on whether the MCS index falls above or below the threshold.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a transmission power for a synchronization signal block (SSB) transmission by a base station, the indicated transmission power different than a default transmission power for SSB transmissions by the base station. The UE may determine a received power with which the SSB transmission is received at the UE. The UE may receive one or more downlink transmissions from the base station based at least in part on the received power for the SSB transmission and a difference between the default transmission power and the indicated transmission power for the SSB transmission.

Abstract: Bandwidth part (BWP) configurations supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. Full duplex (FD) frequency-based BWP configurations may, for example, be configured as a subset of defined BWP resources for supporting full duplex operation by base stations and/or user equipments (UEs). Usable bandwidth of a FD frequency-based BWP configuration may be selected from half duplex frequency-based BWPs in legacy BWPs. Bandwidths of usable BWPs for a FD frequency-based BWP configuration may be selected so as to be non-overlapping in frequency. Transition between configurations and modes (e.g., between full duplex frequency-based BWP configurations, between half duplex and full duplex modes, etc.) may be managed to avoid periods in which a communication device cannot perform any uplink or downlink transmissions due to switching between defined BWP configurations, or otherwise reduces BWP switching time. Other aspects and features are also claimed and described.
