Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating a master cell group (MCG) maximum power value and a secondary cell group (SCG) maximum power value. The UE may determine whether a combination of the maximum power values satisfies a threshold. The UE may perform a transmission on the SCG using a first transmit power and a transmission on the MCG using a second transmit power, wherein, based on the combination of the MCG maximum power value and the SCG maximum power value satisfying the threshold, the first transmit power is determined based on a time offset, or wherein, based on the combination of the MCG maximum power value and the SCG maximum power value failing to satisfy the threshold, the first transmit power is determined without using the time offset. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a deadline prior to a first uplink transmission associated with a secondary cell group (SCG), wherein the first uplink transmission is associated with a first priority level; determine whether to perform a second uplink transmission associated with a master cell group (MCG), wherein the second uplink transmission is initiated after the deadline, and wherein the second uplink transmission is associated with a second priority level; and adjust a transmit power of the first uplink transmission based at least in part on at least one of: determining whether to perform the second uplink transmission, or the first priority level and the second priority level. Numerous other aspects are provided.

Abstract: Aspects described herein relate to indicating search spaces and/or control information formats for receiving multicast/broadcast service (MBS) downlink control information (DCI). A device can receive a search space configuration defining one or more search spaces for detecting communications intended for a group of one or more user equipment (UEs), determine a priority for detecting control information transmitted over a control channel based on the one or more search spaces, and perform, based on the priority, detection for the control information over the control channel based on the one or more search spaces and/or the other defined search spaces.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a notification of a change to multicast broadcast (MB) control information associated with at least one MB service to which the UE is subscribed, the MB control information being included in an MB control channel (MBCCH) scheduled by a physical downlink control channel (PDCCH) communication addressed to an MB radio network temporary identifier (MB-RNTI); and monitor one or more resources of the MBCCH to receive updated MB control information based at least in part on receiving the notification of the change to the MB control information. Numerous other aspects are provided.

Abstract: A base station may transmit a broadcast/multicast service in a multicast broadcast single frequency network (MBSFN) area multicast communication. A method of wireless communication at a base station in accordance with an aspect of the present disclosure comprises determining a broadcast/multicast service to be provided to a user equipment (UE) in a multicast broadcast single frequency network (MBSFN) area, and transmitting a tracking reference signal (TRS) to the UE, the TRS indicating information associated with receiving the broadcast/multicast service by the UE.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encored on computer storage media, for fifth generation (5G)-new radio (NR) physical layer (PHY) timing synchronization. In one aspect, a user equipment (UE) computing device may determine a new timing advance (TA) between downlink frames and uplink frames (NTA_new) for a base station (BS) and determine whether the NTA_new may be within a timing advance acceptable range. In another aspect, a BS may determine a timing advance command (TA) for a timing advance group (TAG) for the BS, and send the TA to the UE computing device. In determining the timing advance command, the TA may be configured by the BS to cause the UE computing device to determine that a new timing advance between downlink frames and uplink frames (NTA_new) for the BS using the TA is within a timing advance acceptable range.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication of a first cell associated with a first uplink carrier and a first downlink carrier and a second cell associated with a second uplink carrier, wherein the second cell comprises an uplink-only cell. The UE may receive, via the first downlink carrier of the first cell or via the second downlink carrier associated with a third cell, a second indication of subsequent communications to be performed via the first uplink carrier of the first cell, the second uplink carrier of the second cell, or both. The UE may perform the subsequent communications according to the second indication, wherein the subsequent communications comprise at least one of access communications, uplink communications, or both.

Abstract: Scheduling information configured to schedule a secondary uplink on a second cell is received on a first cell. Downlink reference signals (DL RSs) are received on the first cell, or radio resource control (RRC) signaling configuring a third cell is received and the DL RSs are received on the third cell. The secondary uplink is transmitted on the second cell. An apparatus receives RRC signaling configuring a location of DL RSs associated with a secondary uplink. The DL RSs are at least one of: within a first carrier bandwidth or a first bandwidth part (BWP) of the secondary uplink, within a second carrier bandwidth or a second BWP of a second cell configured to the apparatus for a non-secondary uplink, or are not within any cell configured to the apparatus. The apparatus transmits the secondary uplink at a power or with timing control determined with the DL RSs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, capability information indicating a set of uplink transmission capabilities. The UE may transmit, to the network node, an indication of a power class switch from a first power class associated with a first uplink transmission power to a second power class associated with a second uplink transmission power. The UE may transmit, to the network node, an indication of a power class switching mode associated with the power class switch. The UE may transmit, to the network node, an uplink transmission based at least in part on one or more revised uplink transmission capabilities, from the set of uplink transmission capabilities, associated with the power class switching mode. Numerous other aspects are described.
