Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a transmission type for a physical downlink shared channel, wherein the transmission type is a multicast transmission type or a unicast transmission type. The UE may determine, based at least in part on the transmission type for the physical downlink shared channel, a transmission configuration indicator state, of a plurality of possible transmission configuration indicator states, that corresponds to a quasi-co-location assumption, of a plurality of possible quasi-co-location assumptions, for the physical downlink shared channel. The UE may decode the physical downlink shared channel based at least in part on the transmission configuration indicator state. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for narrowband transmissions with finer granularity of reserved resources. A method that may be performed by a user equipment (UE) includes receiving a configuration indicating first resource elements (REs) reserved from being used for narrowband Internet of things (NB-IoT) transmissions in a subframe; determining second REs, in the subframe, for narrowband reference signals (NRSs), based on the configuration; and processing the NRSs on the second REs in the subframe.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first common frequency resource (CFR) configured for multicast downlink communications and associated with a first bandwidth part, and an indication of a second CFR configured for broadcast downlink communications and associated with a second bandwidth part. The UE may determine whether to switch a bandwidth part for receiving downlink communications based at least in part on the indication of the first CFR and the indication of the second CFR. Numerous other aspects are provided.

Abstract: A user equipment (UE) selects or reselects a target cell of a non-terrestrial network or resumes connectivity with the target cell after a satellite handover for a permanently fixed low Earth orbit (LEO) cell. The target cell is a serving or non-serving cell. The UE determines a cell type of the target cell. The cell type may be a LEO cell type, a geostationary Earth orbit (GEO) cell type, a moving cell type, a fixed cell type, a temporarily fixed LEO cell type, or a permanently fixed LEO cell type. The UE completes selection or reselection of the target cell or completes the connectivity with the target cell, based on the cell type.

Abstract: A method for wireless communication at a user equipment (UE) includes receiving, from a base station, multicast data via a multicast channel. The method also includes transmitting, to the base station, multicast feedback based on receiving the multicast data. In some examples, the multicast feedback is associated with a group of UEs including the UE. The method further includes receiving, from the base station, a re-transmission of the multicast data on the multicast channel or a unicast channel based on one or more of a number of UEs served by the base station, a number of UEs from the group of UEs providing the multicast feedback, or a radio channel condition.

Abstract: A method, base station (BS), user equipment (UE), apparatus, and computer program product for wireless communication are provided. A BS and a UE may communicate using a narrowband Internet of Things (NB-IoT) communication system. However, a frequency, time, and/or power associated with transmission of a SIB1-NB on a non-anchor carrier may not be configured for NB-IoT. In some aspects, the BS may determine parameters, such as a time domain location parameter, a frequency domain location parameter, a quantity of repetitions, a power boosting parameter, and/or the like for a transmission in NB-IoT. In some aspects, a UE may determine to transmit a connection request message on a different carrier than a random access channel message.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station, a first indication to disable hybrid automatic repeat request (HARQ) feedback for a number of instances of a multicast transport block (TB). The method also includes receiving, from the base station, a second indication identifying a value of the number of instances of the multicast TB. The method further includes receiving, from the base station, one or more instances of the multicast TB. The method still further includes determining, based on the one or more received instances, whether the multicast TB is recoverable. The method further includes selectively transmitting, to the base station, HARQ feedback after all instances of the multicast TB have been transmitted by the base station based on the determination of whether the multicast TB is recoverable.
