Abstract: This disclosure provides systems, methods and apparatus for aperiodic measurement configurations. In one aspect, delaying transitioning of a secondary cell group (SCG) to an active state until a next synchronization signal block (SSB) or periodic reference signal may result in an excessive delay in obtaining network resources of the SCG. Some aspects described herein enable a base station (BS) to transmit signaling using a master cell group (MCG) cell to schedule resources for an aperiodic reference signal transmission and measurement using the SCG. For example, the BS may transmit signaling to a user equipment (UE) to identify a reference signal resource for an aperiodic reference signal transmission and measurement. In this case, the BS may transmit the aperiodic reference signal using an SCG cell, and the UE may measure the aperiodic reference signal and provide a report identifying the measurement of the aperiodic reference signal.

Abstract: Various aspects of the present disclosure generally relate to frequency hopping within a virtual BWP. In son aspects, a UE may determine a virtual bandwidth part (BWP) in which to frequency hop from a first narrow BWP to a second narrow BWP by a frequency offset. The virtual BWP may have a same subcarrier spacing as the first narrow BWP and a larger bandwidth than the first narrow BWP. The UE may perform communication based at least in part on frequency hopping within the virtual BWP. Numerous other aspects are provided.

Abstract: In an aspect, a UE and BS perform a RACH procedure whereby a preamble sequence group for a preamble is associated with a downlink receive capability of the UE. In another aspect, a UE and BS perform a RACH procedure whereby a preamble sequence group is associated with a group-specific RA-RNTI that is used to scramble an associated DCI communication. In another aspect, UEs performing a RACH procedure with a BS via different sets of ROs may monitor the same GC-DCI scrambled with a common RA-RNTI. In another aspect, a UE and BS perform a 2-Step RACH procedure whereby a Msg-A payload includes information indicative of a downlink receive capability level associated with the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A group of random access channel opportunities are identified over which to transmit a preamble associated with a random access channel procedure. A preamble sequence group associated with the identified group of random access channel opportunities is determined based on a repetition level associated with the preamble sequence group. At least one downlink message associated with the random access channel procedure is received based on the repetition level.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may transmit a plurality of repetitions of a cell-common wakeup signal (WUS) on a different transmit beam in each monitoring occasion of one or more monitoring occasions. Another apparatus may beam sweep receive beams in each monitoring occasion to receive the cell-common WUS and to identify a transmit beam/receive beam pair for receiving a paging communication in a paging occasion associated with the transmit beam.

Abstract: Certain aspects of the present disclosure provide techniques for detecting power consumption conditions to trigger transmission of user equipment (UE) assistance information (UAI) for a reconfiguration request. For example, an example method by a UE generally includes detecting one or more conditions associated with at least one metric related to UE power consumption; and transmitting UAI to a network entity, in response to the detection, to request a reconfiguration of the UE to operate according to a set of one or more parameters selected based on a value of the at least one metric.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may inform a base station of multiple transmission-antenna switching capabilities supported by the UE. The supported transmission-antenna switching capabilities may include a first transmission-antenna switching capability and a second transmission-antenna switching capability. The UE may receive a message that triggers the UE to switch from using a first configuration associated with the first transmission-antenna switching capability to using a second configuration associated with the second transmission-antenna switching capability. The UE may perform a sounding procedure using the second configuration associated with the second transmission-antenna switching capability based on receiving the message.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for interference management with adaptive resource block (RB) allocation. In an exemplary method, a user equipment (UE) receives, from a base station (BS), an indication of a first set of resource blocks (RBs) to receive a first downlink (DL) transmission in a time interval, the UE receives, from the BS, an indication of a dynamically allocated second set of RBs to receive a second DL transmission from the BS in the time interval, and the UE alters one or more parameters of a receiver, based on the second set of RBs, when receiving the second DL transmission on the second set of RBs. Altering the one or more parameters may include switching a phase-locked loop (PLL) of the receiver to a center frequency determined based on the second set of RBs.

Abstract: A user equipment (UE) can report direct current (DC) subcarrier location information for a subset of possible combinations of bandwidth parts and component carriers supported by a base station. In one aspect, the UE can receive, from a scheduling entity, a message for activating a first combination of bandwidth parts (BWPs) and component carriers (CCs) in a list including a subset of combinations of BWPs and CCs configured for the UE. The UE can report direct current subcarrier location information for the first combination of BWPs and CCs to the scheduling entity.
