Abstract: Various aspects provide a method for radio resource allocation to support multicast services from a 5G-NR base station. In some aspects, the method may be performed by a processor of the base station. Various aspects include determining a multicast bandwidth part (BWP) within a carrier bandwidth, sending an indication of the multicast BWP to one or more user equipment (UE) computing devices in communication with the base station, and scheduling transmission of multicast data in the multicast BWP.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may determine a beam configuration associated with a set of directional beams of a base station. The beam configuration may include a set of identifiers associated with the set of directional beams. The UE may determine beam position information associated with a coverage area of each directional beam of the set of directional beams based on the beam configuration. Additionally or alternatively, the UE may determine beam classification information associated with the coverage area of each directional beam of the set of directional beams based on the beam configuration. The UE may select a directional beam of the set of directional beams based on the beam position information and the beam classification information, and communicate with the base station using the selected directional beam.

Abstract: Aspects described herein relate to receiving an update value for a timing advance of a satellite link between the UE and a base station, computing, based on the update value for the timing advance, a portion of a timing difference between the update value and a previous value for the timing advance of the satellite link that is corrected by closed loop timing advance control from the base station, computing, based at least in part on computing the portion, a total value for the timing advance of the satellite link, and applying, at the UE and based at least in part on the total value for the timing advance of the satellite link and the closed loop timing advance control, an applied timing advance for communicating with the base station.

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 loss of coherence associated with the UE. The UE may perform at least one adjustment to a transmission parameter or a reception parameter based at least in part on the indication of the loss of coherence. For example, the adjustment to the transmission parameter may include adjusting a transmit power, adjusting a transmit frequency, adapting a transmission time, changing an antenna port, or a combination thereof. Additionally, or alternatively, the adjustment to the reception parameter may include refraining from joint channel estimation across a plurality of slots, adjusting a downscaling parameter or a frequency tuning associated with at least one reception antenna, refraining from blind decoding, or a combination thereof. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for neighbor cell measurements for narrowband communications. An example method generally includes detecting a trigger to take neighbor cell measurements while a user equipment is in a radio resource control (RRC) connected state with a serving cell, based at least in part on a threshold applied to a channel condition metric measured for the serving cell and one or more additional conditions. The method also includes taking neighbor cell measurements in response to detecting the trigger.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a duration of a first gap that precedes a reference signal, based at least in part on a polarization of the reference signal. The UE may determine a duration of a second gap that succeeds the reference signal, based at least in part on the polarization of the reference signal. The UE may perform a measurement of the reference signal based at least in part on the first gap and the second gap. 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 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.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may enable selection of a modulation order (Qm) parameter, a transport block size (TBS) parameter, a quantity of subframes in a transport block (NSF) parameter, and/or the like. For example, based at least in part on receiving a downlink control information or another factor, a user equipment may select, for example, a table of Qm, TBS, and NSF values and may select a particular set of a Qm value, a TBS value, and an NSF value from the table. In this way, the UE may use a higher order modulation and coding scheme in, for example, a narrowband Internet of Things deployment.
