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: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit a random access message (e.g., a message 3) associated with a random access procedure. A hybrid automatic repeat request (HARQ) feedback may be disabled for the random access procedure. The UE may initiate a contention resolution window associated with the random access procedure for a first downlink data channel transmission of a set of downlink data channel transmissions associated with the random access procedure. The UE may receive, during the contention resolution window, the first downlink data channel transmission carrying a contention resolution medium access control-control element (MAC-CE). The UE may transmit acknowledgment information for the first downlink data channel transmission carrying the contention resolution MAC-CE based on an indication to enable the HARQ feedback.

Abstract: A base station may transmit a broadcast/multicast service in a multicast broadcast single frequency network (MBSFN) area multicast communication. A method of wireless communication at a base station in accordance with an aspect of the present disclosure comprises determining a broadcast/multicast service to be provided to a user equipment (UE) in a multicast broadcast single frequency network (MBSFN) area, and transmitting a tracking reference signal (TRS) to the UE, the TRS indicating information associated with receiving the broadcast/multicast service by the UE.

Abstract: A scheduling offset between an uplink and downlink radio frame timing structure of a user equipment (UE) may be updated to provide for more efficient utilization of hybrid automatic repeat request (HARQ) processes in a non-terrestrial network. For instance, different UEs may experience different round trip delays (RTDs) with a non-terrestrial cell. Different UEs may be configured with different scheduling offsets such that scheduling delays may be reduced and HARQ processes identifiers may be reused more rapidly. Additionally or alternatively, wireless communications systems may define one or more separation distances (or timing thresholds) for timing between communications and HARQ processes may be reused based on the separation distance threshold (e.g., such that a satellite may reuse a HARQ process ID for two scheduled communications that have not yet been performed by the UE).

Abstract: Certain aspects of the present disclosure provide techniques for communicating segment-based pre-compensated uplink signals in a non-terrestrial network. A method that may be performed the UE includes transmitting capability information indicating whether the UE needs time gaps between transmission segments associated with uplink signals to be transmitted by the UE in a non-terrestrial network (NTN), obtaining, based at least in part on the capability information, configuration information configuring the time gaps between the transmission segments associated with the uplink signals to be transmitted by the UE, and transmitting the uplink signals in one or more transmission segments based on the configuration information.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The UE detects one or more conditions are met for transmitting a medium access control (MAC) control element (CE) providing assistance information to a network entity for scheduling. In response to the detection, the UE then takes one or more actions to obtain uplink (UL) resources for transmitting the MAC CE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that indicates whether a multicast and broadcast service (MBS) physical downlink shared channel (PDSCH) scheduled by downlink control information (DCI) is associated with a second PDSCH processing capability, wherein the second PDSCH processing capability has a shorter duration than a first PDSCH processing capability. The UE may receive, from the base station, the MBS PDSCH scheduled by the DCI. The UE may transmit, to the base station and based at least in part on the indication, hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback in accordance with the first PDSCH processing capability or the second PDSCH processing capability. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide systems and methods for informing a user equipment (UE) that which beam the UE is being served, for example, such as in relation to bandwidth part (BWP) switching in a non-terrestrial network (NTN). According to certain aspects, a network entity may transmit to a user equipment (UE) signaling indicating at least one BWP switch. The network entity provides, to the UE, an indication of a serving synchronization signal block (SSB) for the UE to use after the BWP switch.
