Abstract: Methods, systems, and devices for wireless communications are described. For a set of scheduled transmission instances of a data communication, a transmitting network node may determine a first spatial filter to apply for a first subset of the scheduled transmission instances configured to provide the data communication and a second spatial filter to apply for a second subset of the scheduled transmission instances configured to allow energy harvesting at an energy harvesting device. In some cases, the transmitting network node may indicate a first quasi co-location (QCL) relation to use for the first subset of the scheduled transmission instances configured to provide the data communication to the network node receiving the data transmissions, and the transmitting network node may indicate a second QCL relation to use for the second subset of the scheduled transmission instances configured to allow energy harvesting to the energy harvesting device.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) and a network entity may support a configured grant (CG)-specific retransmission timer configuration based on a traffic type to be communicated using a given CG. For example, the network entity may indicate a CG for uplink transmissions and may indicate a retransmission timer that is specific to the CG. As such, the UE may transmit a data message in accordance with the CG and may select a time period during which to monitor a downlink control channel for control information indicating a retransmission request for the data message in accordance with a value of the retransmission timer. Additionally, or alternatively, the UE and the network entity may support a downlink-to-uplink configuration dependency for determining an uplink periodicity of a CG based on a downlink periodicity.

Abstract: Certain aspects provide a method for wireless communication by a first user equipment (UE), such as a receiver (RX) UE. The method generally includes receiving signaling configuring the first UE with a discontinuous reception (DRX) mode having one or more DRX ON durations for sidelink communications with at least a second UE, and deciding to extend a DRX ON duration of the one or more DRX ON durations configured for the first UE when the first UE is in the DRX ON duration and when one or more conditions are met.

Abstract: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support use of a connected mode RS in an unconnected mode according to one or more aspects. In a first aspect, a method of wireless communication includes operating, by a user equipment (UE), in an unconnected mode. The method also includes determining, by the UE, reference signal (RS) configuration settings for the unconnected mode. The method includes monitoring, by the UE, for a reference signal based on the RS configuration settings. The method further includes receiving, by the UE, a RS transmission in the unconnected mode based on the RS configuration settings. Other aspects and features are also claimed and described.

Abstract: Wireless devices are configured to facilitate UE assisted bandwidth part (BWP) selection in wireless communication systems. According to one example, a scheduled entity can receive an RRC reconfiguration message indicating a handover from a source cell to a target cell, identify uplink data in the buffer, and send an enhanced UE assistance information (UAI) transmission to the target cell, the enhanced UAI indicating a preferred BWP of the target cell. In addition, a scheduling entity can receive an enhanced UAI transmission from a scheduled entity indicating a preferred BWP for the scheduled entity, and select the preferred BWP for communication with the scheduled entity from the enhanced UAI. Other aspects, examples, and features are also included.

Abstract: Certain aspects of the present disclosure provide techniques for identifying, from a resource pool allocated for sidelink communications between UEs, a first number of resources for transmissions from the first UE to a second UE based on a set of one or more parameters shared between the first UE and the second UE and identifying, from the resource pool, a second number of resources for transmissions from the second UE to the first UE based on the shared set of one or more parameters. The first UE may communicate with the second UE using the first and the second number of resources and avoid using the remaining available resources for power saving. For example, the first UE and the second UE may avoid sidelink communications on time slots on which no subchannels belong to either the first subset or second number of the resources.

The apparatus may receive, from a base station, an indication of a plurality of transmission schedules for at least one of a plurality of PUSCHs or a plurality of PDSCHs, the indication including a time gap prior to a transmission of each of the plurality of PUSCHs or each of the plurality of PDSCHs. The apparatus may also receive, from the base station, DCI identifying at least one transmission schedule for at least one PUSCH of the plurality of PUSCHs or at least one PDSCH of the plurality of PDSCHs. Further, the apparatus may transmit, to the base station, the at least one PUSCH or receive, from the base station, the at least one PDSCH based on the at least one transmission schedule in the received DCI.
