Abstract: Methods, systems, and devices for wireless communications are described. A communications device such as a user equipment (UE) may receive a control message that indicates at least one transmission configuration to apply for bandwidth part (BWP) switching between multiple BWPs, to apply for component carrier (CC) switching between multiple CCs, or both. The at least one transmission configuration may be associated with a plurality of scheduled transmissions (such as semi-persistent scheduling (SPS) or configured grant (CG) transmissions) associated with a BWP or CC configuration. The UE may then receive a switch command to switch from a first BWP to a second BWP, from a first CC to a second CC, or both. The UE may then transmit one or more scheduled transmissions in accordance with the at least one transmission configuration.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a wireless network device (e.g., a base station or a transmission reception point (TRP) of the base station), a first control message comprising an indication of a set of energy saving modes of the wireless network device. The UE may receive a second control message indicating a first energy saving mode from the set of energy saving modes, where the first energy saving mode may be indicative of a number of channel state information (CSI) reference signal (CSI-RS) resources used by the wireless network device. The UE may monitor one or more of the CSI-RS resources for a CSI-RS in accordance with the first energy saving mode, and transmit, to the wireless network device, CSI feedback determined based on measurements made by the UE of the CSI-RS.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an indication of a capability associated with maintaining phase continuity and power consistency for demodulation reference signal (DMRS) bundling between a full-duplex slot and a half-duplex slot. The UE may transmit a first signal during a first slot of a first time domain window (TDW) associated with the DMRS bundling. The UE may determine whether to terminate the first TDW based on the capability associated with maintaining the phase continuity and the power consistency between the full-duplex slot and the half-duplex slot. The UE may transmit a second signal during a second slot of the first TDW or a second TDW based on the determination of whether to terminate the first TDW.

Abstract: Methods, systems, and devices for wireless communication are described. A network entity may transmit control signaling that indicates a format for group common downlink control information (DCI) associated with tracking reference signal resources. The network entity may transmit the group common DCI that indicates a downlink power control configuration to be applied during transmission of tracking reference signals. A user equipment (UE) may receive the group common DCI in accordance with the format and monitor for tracking reference signals during the tracking reference signal resources in accordance with the downlink power control configurations.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) determines (e.g., based on an indication from base station) one or more physical random access channel (PRACH) preamble transmission parameters associated with one or more PRACH coverage enhancement (CE) levels of a RACH procedure. The UE and the base station perform a RACH procedure in accordance with the one or more PRACH preamble transmission parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify physical uplink shared channel (PUSCH) configuration parameters to send a handover completion message at the end of a handover. A source cell may notify the UE of a handover via a handover command and the UE may acquire system information, and in some cases, a downlink message, from a target cell. The UE may identify a waveform configuration, numerology configuration, and/or modulation scheme using information from the handover command message, the system information, and/or the downlink message. The UE may also determine occasions for transmitting a PUSCH. For example, each occasion may include a set of time-frequency resources on which the PUSCH may be transmitted. The UE may send the handover completion message to the target cell via the PUSCH, during the one or more identified occasions, using the identified configuration parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first message indicating that a network entity, in wireless communication with the UE, is operating in a first energy saving mode of multiple energy saving modes. The UE may receive information indicating multiple sets of parameters for a radio link monitoring (RLM) operation, each of the sets of parameters being associated with a different energy saving mode. The UE may perform the RLM operation using one or more parameters of a first set of parameters (e.g., a maximum beam failure instance count parameter, one or more threshold parameters, and other parameters) associated with the first energy saving mode. The may use a second set of parameters to perform the RLM operation in response to the network entity switching from operating in the first energy saving mode to operating in the second energy saving mode.

Abstract: Aspects relate using peak reduction tones on a supplementary uplink to reduce peak to average power ratio on the supplementary uplink. For example, when a UE elects to switch from a primary carrier (e.g., a 5G NR carrier) to an SUL carrier (e.g., in a limited coverage scenario), the UE may use a defined set of PRTs to transmit data on the SUL carrier. In some examples, PRTs may be used on multiple carriers. For example, a first set of PRTs may be defined for an SUL carrier and a second set of PRTs may be defined for another carrier.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support allocation of resources for a physical broadcast channel (PBCH) for reduced bandwidth devices. In a first aspect, a method includes monitoring, by a user equipment (UE) configured for reduced bandwidth operation, at least a subset of a first set of time and frequency resources allocated to a synchronization signal block (SSB) for UEs configured for non-reduced bandwidth operation. The SSB includes synchronization signals and a PBCH. The method includes monitoring, by the UE, a second set of time and frequency resources allocated to the PBCH for UEs configured for reduced bandwidth operation. The method includes receiving, by the UE, the synchronization signals and the PBCH within at least the subset of the first set of time and frequency resources and the second set of time and frequency resources. Other aspects and features are also claimed and described.
