Abstract: Certain aspects of the present disclosure provide techniques for search space alignment for control channel monitoring. A method that may be performed by a user equipment (UE) includes aligning a first set of monitoring occasions associated with a common search space (CSS) with a second set of monitoring occasions associated with a UE-specific search space (USS). The method further includes monitoring for signals from a network entity via at least one of the CSS or the USS in the aligned first and second set of monitoring occasions. The method also includes communicating with a network entity based on reception of at least one of the signals in the aligned first and second set of monitoring occasions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication of a configuration for a time domain (TD) control resource set (CORESET) for single carrier waveforms that dynamically changes one or more parameters associated with the TD CORESET. The UE may receive, from the base station, a physical downlink control channel based at least in part on the indication of the configuration for the TD CORESET. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods, and apparatuses for determining whether a channel state information reference signal (CSI-RS) is to be transmitted, and a configuration for transmission of the CSI-RS on a wideband based on an outcome of a listen-before-talk (LBT) operation in multiple sub-bands of the wideband. In one aspect, a base station may transmit sub-band usage information indicating sub-band availability before the CSI-RS, thereby allowing a user equipment (UE) to determine whether the CSI-RS will be transmitted and, if so, on which sub-bands the CSI-RS will be transmitted. Furthermore, rate matching configurations are provided based on whether sub-band usage has been received, based on which sub-bands are available. Still further, power configurations and resource element selection criteria are provided for wideband CSI-RS and CSI feedback.

Abstract: Aspects described herein relate to sidelink transmissions. In an example, a first user equipment (UE) may receive, from a network entity, a first sidelink grant for a transmission between the first UE and a second UE; communicate the transmission according to the first sidelink grant to the second UE; determine initiation of a sidelink round trip timer subsequent to communicating the transmission to the second UE; and initiate an inactive mode for the first UE based on a second grant not being received from the network entity before completion of a duration of a sidelink retransmission timer that was initiated upon completion of a duration of the sidelink round trip timer, the first UE being configured out of an ON duration of a discontinuous reception (DRX) cycle, and an inactivity timer expiring before completion of the duration of the sidelink retransmission timer.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an uplink power control configuration for a sounding reference signal (SRS) resource set associated with an uplink component carrier, wherein the uplink power control configuration configures separate power control adjustment states between SRS transmissions and physical uplink shared channel (PUSCH) transmissions, and wherein the uplink power control configuration indicates one of a first SRS power control adjustment state or a second SRS power control adjustment state. The UE may transmit, to the base station, an SRS based at least in part on the uplink power control configuration for the SRS resource set. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for facilitating reference signal multiplexing with downlink data are disclosed herein. An example method for wireless communication at a user equipment (UE) includes receiving, from a base station, a reference signal configuration associated with at least one of a tracking reference signal (TRS) and a channel state information reference signal (CSI-RS), the reference signal configuration comprising a symbol level rate matching configuration, a precoder configuration, or a guard tone configuration. The example method also includes receiving, from the base station, a transmission comprising at least a reference signal and data based on the reference signal configuration.

Abstract: Certain aspects of the present disclosure provide techniques for control channel repetition and control information transmission on a data channel. One aspect provides a method for wireless communication by a user-equipment (UE). The method generally includes receiving, from a base station (BS), a scheduling of a control channel resource set for transmission of an uplink control channel repetition; determining whether the uplink control channel repetition using the control channel resource set will be dropped; and transmitting, to the BS, the uplink control channel repetition on another control channel resource set based on the determination.

The network entity may further transmit an indication including the beam sweep pattern to a user equipment (UE). In another aspect, a UE may receive a beam sweep pattern for at least one of a SPS based downlink periodic transmission, an uplink control transmission for the SPS based downlink periodic transmission, or a CG based uplink periodic transmission from a network entity.
