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, configuration information indicating a first set of open-loop power control parameters associated with a first control resource set (CORESET) pool index value and a second set of open-loop power control parameters associated with a second CORESET pool index value. The UE may receive, via a first CORESET, a first downlink control information (DCI) message that schedules a first physical uplink shared channel (PUSCH) message. The UE may transmit the first PUSCH message using a transmit power level, based on the first set of open-loop power control parameters or the second set of open-loop power control parameters, based on a CORESET pool index value associated with the first CORESET. Numerous other aspects are provided.

Abstract: A method of wireless communication performed by a wireless communications device may include receiving, from a second wireless communication device, one or more signals associated with a beam parameter, determining, for each of a plurality of locations within a first zone, a first signal measurement for the one or more received signals, determining, at each of a plurality of locations within a second zone, a second signal measurement for the one or more received signals, wherein the second zone is different from the first zone, and determining whether the second wireless communication device satisfies an interference condition based at least in part on a cumulative distribution of at least one of the first signal measurements at the plurality of locations within the first zone or a cumulative distribution of at least one of the second signal measurements at the plurality of locations within the second zone.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on an access link from a base station, a first downlink control information (DCI) that schedules a first communication on a physical sidelink shared channel (PSSCH) and a second DCI that schedules a second communication on the PSSCH. The first communication and the second communication may be scheduled according to a rule for overlapping or ordering communications on the PSSCH that are associated with one or more hybrid automatic repeat request identifiers. The UE may transmit the first communication and the second communication as scheduled. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide for managing random access channel (RACH) procedures in wireless communication systems. In some examples, a UE includes a processor, a transceiver communicatively coupled to the processor and configured to communicate with a scheduling entity in the wireless communication network, and a memory communicatively coupled to the processor. The processor is configured to receive a signal from a base station at the beginning of a fixed frame period during a two-step random access procedure, determine whether a resource for a transmission occasion overlaps one or more symbols located at an edge of the fixed frame period, and discard the resource for the transmission occasion at the UE when the resource overlaps the one or more symbols located at the edge of the fixed frame period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a radio resource control (RRC) message, the RRC message including an indication of whether group-based beam reporting is enabled for the UE. The UE may transmit a group-based beam report based at least in part on the indication that the group-based beam reporting is enabled for the UE. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a first message to indicate a sidelink bandwidth part (BWP) switch, for the first UE, to a first sidelink BWP, wherein the first message includes an indication of the first sidelink BWP and a first sidelink resource pool in the first sidelink BWP. The UE may receive, from the second UE, a second message that confirms the sidelink BWP switch for the first UE. The UE may transmit, to the second UE, a third message to activate the sidelink BWP switch, for the first UE, to the first sidelink BWP, based at least in part on receiving the second message that confirms the sidelink BWP switch. Numerous other aspects are described.

Abstract: User equipment associated with a legacy network may utilize a bottom-to-top search technique to identify relevant control channel samples. Generating a control channel that is configured for the bottom-to-top search technique may lead to poor performance in a single-carrier waveform, which may be disadvantageous as networks move toward New Radio. In some aspects, described herein, a base station generates a control channel that is configured to minimize gaps in the control channel, and a user equipment performs a top-to-bottom search technique to identify relevant control channel samples. By using the top-to-bottom search technique, degradation of single-carrier waveforms is reduced and efficiency is improved.

Abstract: Methods, systems, and devices for wireless communications are described to support determination of an uplink beam for uplink transmissions. A base station may configure a user equipment (UE) with multiple sets of sounding reference signal (SRS) resources that may be used for uplink transmissions from the UE. In some cases, each set of SRS resources may be configured with one associated channel state information reference signal (CSI-RS) resource, and each CSI-RS resource may correspond to an uplink beam. The base station may transmit a downlink control message to the UE, indicating one or more selected SRS resource sets and one or more selected SRS resources within each of the one or more selected SRS resource sets. The UE may transmit an uplink transmission with a beam associated with the indicated SRS resource set.
