Abstract: Certain aspects of the present disclosure provide techniques for coordinated power savings configurations for access link and sidelink(s). A wireless node may receive information from a user equipment (UE) over a sidelink. In some aspects, the wireless node forwards the information to a base station (BS) over an access link and receives, from the BS, a first power savings configuration for the access link and a second power savings configuration for the sidelink. In some aspects, the wireless node receives, from a BS, a first power savings configuration for an access link and determines a second power savings configuration for the sidelink based on the information and the first power savings configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a differential UE-specific timing advance (TA) based at least in part on a difference between a first UE-specific TA associated with a current global navigation satellite system (GNSS) position fix and a second UE-specific TA associated with a previous GNSS position fix. The UE may transmit, to a non-terrestrial network (NTN) node, an uplink message at a time that is based at least in part on the differential UE-specific TA. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit multiple repetitions of a paging early indication (PEI) signal to a user equipment (UE) to indicate that the UE is to receive paging signaling in a paging occasion. In some cases, a PEI occasion for transmitting a PEI repetition may have a scheduling conflict. For example, a PEI occasion may collide with other downlink signaling. A UE may implement techniques to resolve scheduling conflicts or collisions for PEI repetitions. For example, the UE may be configured to receive either colliding PEI signaling or colliding downlink signaling based on priorities of the signaling. Additionally, or alternatively, PEI signaling may be shifted (e.g., delayed) until after the downlink signaling ends. In some cases, a UE may be configured with a subset of blind decoding hypotheses for PEI decoding.

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 receive a first message indicating a first set of parameters associated with time domain resource allocation (TDRA) information for a first quantity of shared channels. The UE may receive a second message (e.g., downlink control information (DCI)) scheduling a set of shared channels, a second quantity of the set of shared channels exceeding the first quantity. The set of shared channels may include a first subset of shared channels corresponding to the first quantity, and a second subset of shared channels including additional shared channels. In addition, the UE may determine a second set of parameters for the second subset based on the first set of parameters, where the UE and a network entity may communicate the first subset using the first set of parameters and the second subset using the second set of parameters.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a time period during which the UE is configured to receive grants scheduling communications for the UE, wherein the grants are associated with a first grant format type. The UE may determine that the grants include a feedback process identifier exceeding a threshold value. The UE may maintain a power saving state of a discontinuous reception procedure for a feedback process associated with the feedback process identifier during the time period based at least in part on the feedback process identifier exceeding the threshold value.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a waveform threshold for selecting a waveform type for transmitting a message of a random access procedure. The UE may select the waveform type for the message of the random access procedure based on the waveform threshold and a value associated with a power of signals received at the UE. The UE may transmit the message of the random access procedure to a network entity according to the waveform type selected for the message.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for measuring, filtering, and reporting cross-link interference (CLI) in cases where not all aggressor user equipments (UEs) are transmitting signals that can be measured by a victim UE. A UE may obtain a set of CLI measurements by performing CLI measurements during a set of CLI measurement occasions. The UE may determine a first subset of the set of CLI measurements that satisfy a CLI measurement threshold and a second subset of the set of CLI measurements that do not satisfy the CLI measurement threshold. The UE may apply a filter to the first subset of the set of CLI measurements, and suppress the filter for the second subset of the set of CLI measurements, to obtain a filtered CLI measurement value. The UE may transmit the filtered CLI measurement value to a base station.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity, such as a base station, may receive, from a first network entity, a broadcast indicating a downlink control channel transmission pattern associated with the first network entity. The network entity may monitor a plurality of receive beams for a plurality of downlink control channel transmissions from the first network entity according to the downlink control channel transmission pattern and may select a communication beam according to one or more cross-link interference (CLI) measurements associated with one or more of the plurality of receive beams in accordance with the monitoring. The network entity may communicate with a user equipment using the selected communication beam and a first set of resources that at least partially overlap in time and frequency with a scheduled communication at the first network entity. The network entity may experience or may cause the measured CLI.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for determining a transmit power of a paging early indication (PEI) transmission. In particular, a user equipment (UE) receives a PEI from a base station indicating whether the UE is being paged during a paging occasion. The UE determines a transmit power of the PEI transmission. In some aspects, the UE determines the transmit power of the PEI transmission based on a configuration of the PEI provided to the UE, which may include an indication of the PEI transmission power as an absolute power value and/or a power offset value with respect to another transmission, signal, or channel. In some aspects, the transmit power of the PEI transmission is based on whether the PEI transmission is a beamformed transmission.
