Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a downlink control information (DCI) message associated with scheduling transmissions for the UE on a plurality of component carriers. The UE may determine, for at least a first component carrier of the plurality of component carriers, that a frequency resource allocation field of the DCI message comprises an indication of a value that is invalid for frequency resource allocation on the first component carrier. The UE may determine, based at least in part on the invalid indication and using a subset of fields of the DCI message corresponding to the first component carrier, that one or more component carriers of the plurality of component carriers are dormant.

Abstract: Wireless communications systems and methods related to acknowledgement/negative-acknowledgement (ACK/NACK) feedback operations for multicast communications are provided. A first user equipment (UE) receives, from a base station (BS), a multicast feedback configuration indicating a first resource configuration for a negative-acknowledgement (NACK) feedback mode; and a second resource configuration for an acknowledgement/negative-acknowledgement (ACK/NACK) feedback mode. The first UE receives, from the BS, a first multicast communication. The first UE transmits, to the BS, a NACK feedback for the first multicast communication based on the first resource configuration. The first UE receives, from the BS, a second multicast communication. The first UE transmits, to the BS, an ACK feedback or a NACK feedback for the second multicast communication based on the second resource configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a search space associated with a physical downlink control channel (PDCCH) corresponding to a multicast/broadcast (MBS) physical downlink shared channel (PDSCH) for at least one MBS PDCCH communication having a payload that is scrambled according to a PDCCH payload scrambling sequence based on a value of a radio network temporary identifier (RNTI), wherein the value of the RNTI is equal to a group-RNTI (G-RNTI) or zero. The UE may receive the at least one MBS PDCCH communication. 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 transmit, to a network node, a first uplink transmission using a first transmit power that is based at least in part on: a first power level associated with the first uplink transmission, and a power scaling factor based at least in part on a power offset. The UE may transmit, to the network node, a second uplink transmission, at least partially overlapping in time with the first uplink transmission, using a second transmit power that is based at least in part on: a second power level associated with the second uplink transmission, a maximum available transmit power, and the first transmit power. 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 receive, in an idle or inactive state and in a common frequency resource (CFR) used for multicast and broadcast services (MBS), a tracking reference signal (TRS) configuration for MBS. The UE may receive a TRS according to the TRS configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate over multiple component carriers (CCs). The UE may receive control signaling indicating a joint feedback codebook configuration for jointly reporting feedback for a first CC, a second CC, and a virtual CC that may be mapped to a third CC and a fourth CC. The UE may then receive downlink control information (DCI) scheduling a first downlink transmission via the first CC and a second downlink transmission on the second CC, or both downlink transmissions may be scheduled via the virtual CC. The UE may transmit a joint feedback message for the first CC, the second CC, and the virtual CC based on the joint codebook configuration.

Abstract: Aspects include systems, methods, devices, and non-transitory processor readable storage mediums for managing a broadcast signal of an apparatus for wireless communication. Various aspects may enable an apparatus to send a message using either omnidirectional transmissions or beamformed transmission based on whether the altitude of the apparatus meets an altitude threshold. In some implementations and aspects, the processor of the apparatus may determine a type of the message and may select the altitude threshold based on the determined message type. In some implementations and aspects, the processor of the apparatus may send the message using beamformed transmissions in response to determining that the message is intended for reception by a certain type of second apparatus.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to monitor search spaces on a primary cell and an secondary cell in a carrier aggregation configuration. The UE may monitor the search spaces for control information according to a shared search space monitoring configuration. Based on the shared search space monitoring configuration, the UE may identify that the secondary cell is a scheduling cell and the primary cell is a scheduled cell (e.g., cross-carrier scheduling). The UE may monitor control channel candidates of search spaces on the primary cell and on the secondary cell for downlink control information messages scheduling data transmissions with the primary cell. In some examples, the cross-carrier scheduled communications may be configured according to a scheduling configuration, which may include one or more scheduling constraints.

Abstract: A method for obtaining flight path information comprises: receiving, at a network entity, a capability report indicating a capability of a UE to report a flight path of the UE; and transmitting, from the network entity, a flight path report message that requests the UE to provide: partial-path reporting by reporting first flight path information indicative of a portion of the flight path of the UE that is less than all of the flight path; or triggered reporting by reporting second flight path information in response to occurrence of a trigger event, the second flight path information indicative of at least some of the flight path of the UE; or differential reporting by reporting third flight path information indicative of a difference between a present flight path of the UE and a previous flight path of the UE; or any combination thereof.
