Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect an occurrence of a triggering event associated with power headroom reporting. The UE may transmit, from the UE to a base station, a power headroom report (PHR) medium access control (MAC) control element (CE) based at least in part on the occurrence of the triggering event, wherein the PHR MAC-CE is for one or more uplink component carriers of the UE that are associated with one or more control resource set pool index values. Numerous other aspects are provided.

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: Some techniques and apparatuses described herein permit a user equipment (UE) to transition among different power configurations, which include different values for different power parameters, that impact an amount of power consumed by the UE. In some aspects, these transitions may be signaled by a base station based at least in part on traffic volume for the UE, which may assist with improving throughput and/or extending battery life of the UE. Furthermore, these transitions may be signaled dynamically, such as in downlink control information (DCI) and/or a medium access control (MAC) control element (CE) MAC-CE, which may conserve battery power and/or network resources as compared to reconfiguring the UE using an RRC message, and which may allow the UE to be reconfigured quickly as conditions associated with the UE change.

Abstract: Processes, systems, and devices for wireless communications are described. A communication device may monitor a wakeup signal monitoring occasion in an inactive duration of a discontinuous reception (DRX) cycle. The communication device may transmit, in a first active duration of the DRX cycle, a channel state information (CSI) report on one or more resources based on monitoring the wakeup signal monitoring occasion. In some examples, the communication device may transmit an indication that the communication device requests reporting of the CSI report in the first active duration of the DRX cycle. The communication device may, in some examples, receive, in a second active duration of the DRX cycle, control information for the UE based on the CSI report.

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: Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally, or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.

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: In some aspects, a user equipment (UE) determines a transmission gap adjustment (TGA) for a first message (msgA) of a 2 step random access channel (RACH) procedure based on measurement of a reference signal transmitted by a base station as well as the radio resource configuration (RRC) configurations for msgA. In other aspects, a base station transmits a system information block (SIB) or RRC signaling that indicates at least one possible configuration of the TGA, and UEs determine the TGA depending on RRC state. Connected mode UEs having a timing alignment (TA) timer running may determine the TGA based on a previous TA. UEs in other RRC modes determine the TGA based on the possible configuration transmitted in the SIB or RRC signaling. Advantageously, 2 step RACH UEs are able to communicate with the base station without the closed loop TA information provided by a 4 step RACH.

Abstract: Provided herein are various techniques and solutions to paging user equipment (UE). In particular, paging at higher levels of granularity, such as a beam level, for low mobility or stationary UEs in inactive and/or idle states are described. An apparatus may be configured to receive, from a network, a message configuring at least one beam notification area associated with positioning of the apparatus. The at least one beam notification area may include a set of beams corresponding to a set of cells identified by the network as candidates for carrying a paging message for the apparatus in the at least one beam notification area. The apparatus may be further configured to receive the paging message from the network via one of the set of beams corresponding to one of the set of cells in which the apparatus is positioned based on the at least one beam notification area.
