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: Certain aspects of the present disclosure provide techniques for physical downlink control channel (PDCCH) monitoring for multicast-broadcast service (MBS). A method of wireless communications by a wireless node includes obtaining signaling indicating one or more search space (SS) parameters including at least one of: a defined set of control channel element (CCE) aggregation levels or a quantity of one or more PDCCH candidates per CCE aggregation level; and monitoring for one or more PDCCHs scheduling communication via one or more MBS channels based on the one or more SS parameters.

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.

Abstract: A UE receives, from a network entity, an allocation of resources for a sidelink transmission, the allocation of resources including an indication of a destination identifier (ID). The UE transmits the sidelink transmission to a second UE based on the allocation of resources for the sidelink transmission and the destination ID associated with the second UE. A UE receives, from a first UE, a request to form a connection for sidelink communication. The UE measures at least one colliding sidelink transmission from at least one additional UE interfering with a sidelink transmission from the first UE and transmits, to a network entity, a sidelink collision report indicating the measured at least one colliding sidelink transmission from the at least one additional UE. The UE communicates, with the first UE, via the sidelink communication based on an allocation of resources for the sidelink transmission after the sidelink collision report.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of a number of automatic gain control (AGC) symbols included in a sidelink slot structure for sidelink communication. The UE may receive a sidelink communication associated with a sidelink control information (SCI) field that indicates whether the number of AGC symbols are present within the sidelink communication. Numerous other aspects are described.

Abstract: A configuration to enable a base station to schedule cross carrier scheduling of uplink and/or downlink transmissions using a DCI. The apparatus transmits, to a UE, a PDCCH including a cross carrier schedule. The PDCCH comprises DCI configured to schedule an uplink transmission or a downlink transmission. The DCI includes at least one FDRA field indicating RBs for the uplink transmission or the downlink transmission on at least one serving cell of the cross carrier schedule. The apparatus communicates with the UE based on the cross carrier schedule configured by the DCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects generally relate to reducing interference in a user equipment (UE) with respect to non-cell defining synchronization signal and physical broadcast channel block (NCD-SSB) communications. Some aspects more specifically relate to configuring the UE to mitigate interference caused by collisions between the NCD-SSB and a cell-defining SSB (CD-SSB). Some aspects more specifically relate to configuring the UE to mitigate interference and/or other issues that might occur when at least a portion of the NCD-SSB is received during one or more downlink slots or symbols and one or more uplink slots or symbols.

Abstract: Positioning assistance data is broadcast by Transmission Reception Points (TRPs) that includes information that is specific for aerial user equipment (UEs) and information that is for terrestrial UEs. The positioning assistance data may be included in positioning System Information Blocks (posSIBs), and the information for the aerial UEs and information for the terrestrial UEs may be provided together in the posSIB or may be provided in separate posSIBs. The positioning assistance data, for example, may separately list, e.g., the TRPs, resource sets, or resources to be used for positioning aerial UEs.
