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.

Abstract: Methods, systems, and devices for wireless communication are described. Devices may synchronize parameters associated with an encryption key to avoid a key mismatch. In a first example, a transmitter and a receiver may each update a respective parameter at each transmission occasion associated with semi-statically allocated resources, regardless of whether signaling is transmitted in the transmission occasion. In a second example, the transmitter and the receiver may each update the respective parameter based on a slot count, rather than at each transmission occasion. In a third example, the transmitter may indicate a value of a transmitter parameter to the receiver, for example in control signaling or in the signaling in each transmission occasion. In a fourth example, the receiver may be enabled to identify a skipped transmission occasion The receiver may be enabled with a feedback process to indicate the receiver recognized the associated transmission occasion was skipped.

Abstract: Certain aspects provide a method for wireless communication. The method generally includes determining a first configuration for sidelink (SL) communication by a user-equipment (UE), determining a second configuration for uplink (UL) or downlink (DL) communication by the UE, the first configuration and the second configuration being determined to allow the UL or DL communication to overlap in time domain with the SL communication, and transmitting the first configuration and the second configuration to the UE.

Abstract: Certain aspects of the present disclosure provide techniques for carrier group based multiple-input multiple-output (MIMO) layers and antenna adaptation. A method that may be performed by a user equipment (UE) includes receiving a configuration of one or more groups of component carriers (CCs) and, for each group of CCs, one or more sets of configured maximum number of MIMO layers. Each set includes a configured maximum number of MIMO layers associated with each CC in the group. The UE receives an indication of at least one of the one or more sets and determines the configured maximum number of MIMO layers associated with each CC in the corresponding group of CCs based on the indication.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may perform uplink reference signal bundling for access link communications and transmit sidelink communications using time or frequency division multiplexed resources. The UE may determine to drop or to transmit a sidelink communication based on a relationship with multiple instances of an uplink reference signal that are to maintain phase continuity. The UE may drop a sidelink communication when a time duration between two instances of the uplink reference signal is less than or equal to a time threshold value, and may transmit the sidelink communication when the time duration exceeds the time threshold value. In frequency division multiplexed cases, the UE may set a transmission power for each instance of the uplink reference signal, and the sidelink communication may use a remaining amount of power.
