Abstract: Aspects of the present disclosure provide systems and methods for assigning one or more user equipments (UEs) at one or more corresponding starting positions of multiple slots to perform channel access procedures, such as listen before talk (LBT) procedures in New Radio unlicensed band (NR-U) sidelink communications. The network entity may indicate, to a UE, a starting position in a multi-opportunity grant (e.g., a DCI scheduling multiple slots). The network entity may multiplex different transmitter UEs with different starting positions. If the channel accessing procedure is successful, the transmitter UE with the earliest starting position than the rest may block the rest of the transmitter UEs. In some cases, starting position hopping may be used so that the multiple UEs may have different priority at different slots. In some cases, the DCI may include LBT parameters that are inherited from NR-U uplink transmission configurations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for control channel repetition and control information transmission on a data channel. One aspect provides a method for wireless communication by a user-equipment (UE). The method generally includes receiving, from a base station (BS), a scheduling of a control channel resource set for transmission of an uplink control channel repetition; determining whether the uplink control channel repetition using the control channel resource set will be dropped; and transmitting, to the BS, the uplink control channel repetition on another control channel resource set based on the determination.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, an indication associated with a quantity of active hybrid automatic repeat request (HARQ) processes, wherein the quantity of active HARQ processes is dynamically changeable based at least in part on an operating band and an associated subcarrier spacing. The UE may transmit, to the network entity, HARQ feedback based at least in part on the indication associated with the quantity of active HARQ processes. Numerous other aspects are described.

Abstract: An apparatus may be configured to communicate at least one pilot signal with another apparatus according to a first configuration, at least one of a lower frequency density or a higher time density being indicated by the first configuration than a second configuration for a type of pilot signal that includes the at least one pilot signal. The apparatus may be further configured to communicate with the other apparatus based on the at least one pilot signal. Another apparatus may be configured to receive, from a base station, spatial relationship information or transmission configuration indicator (TCI) state information corresponding to a directional beam at the UE for communication on a channel. The apparatus may be further configured to apply the directional beam for communication with the base station on another channel in a sub-6 gigahertz (GHz) frequency band.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station associated with a cell of a time division duplex communication system may determine a guard interval that is less than a maximum time delay, based at least in part on a radius of the cell, for air-to-ground communications; and transmit a scheduling configuration to a user equipment that identifies the guard interval. Numerous other aspects are provided.
