Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive an indication of a first set of resources for feedback and an indication of a second set of resources for feedback, where the second set of resources are associated with a smaller quantity of cyclic shifts than the first set of resources. Accordingly, the mobile station may transmit feedback on either the first set of resources or the second set of resources based at least in part on a distance associated with the feedback. As an alternative, the mobile station may compute a timing advance associated with transmission of feedback. Accordingly, the mobile station may feedback that is shifted in time according to the timing advance. Numerous other aspects are described.

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, 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.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may receive a feedback configuration for providing feedback for downlink communications from a base station. Based on the feedback configuration, the UE may determine whether one or more feedback processes has a multicast-only configuration for multicast data communications, or a multicast-or-unicast configuration for either multicast data communications or unicast data communications. The UE may decode one or more transmissions associated with the one or more feedback processes based on the multicast-only or multicast-or-unicast configuration, and may determine a feedback codebook based on the multicast-only or multicast-or-unicast configuration of the one or more feedback processes. The UE may monitor for retransmissions of one or more multicast data communications based on the feedback process configuration.

Abstract: A method of wireless communication performed by a user equipment (UE) includes receiving, from a base station, a message comprising a multicast downlink grant for a downlink channel associated with a multicast transmission. The method also includes receiving, from the base station, a reference signal associated with the downlink channel. The method further includes transmitting, to the base station, a unicast message comprising a measurement report indicating a measurement of the reference signal associated with the downlink channel. The reference signal may be measured based on receiving the multicast downlink grant.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a connection release message, the connection release message including a resource indicator indicating that a set of resources are to be used for grant-free uplink transmissions by the UE while operating in a disconnected state. The UE may transition from a connected state to a disconnected state based at least in part on the connection release message. The UE may perform, while operating in the disconnected state, the grant-free uplink transmissions using the set of resources.

The UE may transmit, to a second UE in a PC5 radio resource control (RRC) message, capability information that includes an indication that the first UE is an unmanned aerial vehicle (UAV). Numerous other aspects are described.

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 (HARQ) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

Abstract: Aspects described herein relate to retransmission implementations in new radio (NR) wireless communication systems. In one aspect, a network entity may initially perform a multicast transmission and then a multicast retransmission according to a hybrid automatic repeat request (HARQ) process. In another aspect, a user equipment (UE) may initially receive a multicast transmission from a network entity and a subsequent multicast transmission according to a HARQ process. In an additional aspect, a network entity may initially perform a multicast transmission and then a subsequent unicast retransmission according to a HARQ process. In yet another aspect, a UE may initially receive a multicast transmission from a network entity and a subsequent unicast transmission according to a HARQ process.

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.
