Abstract: A method for wireless communication by a network node includes transmitting, to a group of user equipment (UEs), radio resource control (RRC) signaling to configure a function for enabling and disabling hybrid automatic repeat request (HARQ) feedback for a set of N instances of a multicast transport block (TB). The method also includes transmitting, to the group of UEs, the set of N instances of the multicast TB. The method further includes transmitting, to the group of UEs, a downlink control information (DCI) message on a group-common physical downlink control channel (PDCCH) with a cyclic redundancy check (CRC) scrambled by a group-common radio network temporary identifier (RNTI) configured for the group of UEs. The method also includes receiving, from one or more UEs of the group of UEs, a HARQ feedback message associated with one or more instances of the set of N instances after transmitting all N instances.

Abstract: Certain aspects of the present disclosure provide techniques for bandwidth part (BWP) switching by frequency shifting and/or by transmission configuration indicator (TCI) state configuration. A method that may be performed by a user equipment (UE) includes receiving a BWP configuration indicating a frequency location and bandwidth of at least a first BWP; receiving signaling indicating at least one frequency shift to determine a second BWP from a frequency location of the first BWP; and communicating on the second BWP after performing a BWP switch from the first BWP to the second BWP based on the at least one frequency shift.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARM) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, an indication of one of: a quantity of physical uplink control channel (PUCCH) resources in a PUCCH slot for negative acknowledgement (NACK)-only-based multicast feedback, or a quantity of transport blocks (TBs) with the NACK-only-based multicast feedback to be multiplexed in the PUCCH slot. The UE may determine, based at least in part on the indication, the quantity of PUCCH resources in the PUCCH slot for the NACK-only-based multicast feedback. The UE may determine a physical downlink shared channel (PDSCH) processing timeline. The UE may transmit, to the network node, the NACK-only-based multicast feedback using the quantity of PUCCH resources and based at least in part on the PDSCH processing timeline. 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, after an update to a location or a velocity of the UE, a closed-loop frequency pre-compensation and an open-loop frequency pre-compensation. The UE may transmit, after the update to the location or the velocity of the UE, an uplink signal using a frequency pre-compensation that is based at least in part on the closed-loop frequency pre-compensation and the open-loop frequency pre-compensation. Numerous other aspects are described.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus at a UE in NTN are provided. The UE may be configured to receive one or more FPC commands from an NTN. The UE may be further configured to transmit, in response to receiving the one or more FPC commands, an uplink transmission with a frequency change having a total FPC adjustment calculated based on (a) a current UE location update and a current UE velocity update, wherein the total FPC adjustment satisfies one or more threshold requirements, or (b) an intermediary UE location update between the current UE location update and a previous UE location update and an intermediary UE velocity update between the current UE velocity update and a previous UE velocity update.

Abstract: A UE may receive, from at least one cell via at least one bit in a MIB or a SIB, a barring indication based on a supported network of the at least one cell and a supported network of the UE. The supported network of the at least one cell may correspond to a TN or an NTN, and the supported network of the UE may correspond to a TN or an NTN. The UE may skip, based on the received barring indication, a selection of the at least one cell for communication. Accordingly, the UE may not camp on the at least one cell. The barring indication for NTN-supporting UEs and for TN-supporting UEs may be separately indicated via the MIB or the SIB.

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: Methods, systems, and devices for wireless communications are described Generally, the described techniques provide for a user equipment (UE) to perform a beam switching operation from a current beam to a target beam based on a beam switching duration. The UE may transmit a capability report that may include an antenna pointing capability, a list of one or more detailed capabilities, or both to another device, such as a network entity (e.g., a satellite). The UE may perform the beam switching operation based on the capability report. The UE may perform a random access procedure as part of a change of association operation. The UE may receive a control message from the other device, which may be the network entity, that includes an identity of a target network entity, one or more resources for the random access procedure, an indication of the beam switching duration, or any combination.
