Abstract: A user equipment (UE) receives one or more timing advance commands from a non-terrestrial network (NTN). The UE resets, after a GNSS fix, a cumulative timing advance value based on the one or more timing advance commands from the NTN and transmits an uplink transmission with a timing advance based on a self-estimated delay and the cumulative timing advance value. The UE may adjust a self-estimated delay based on at least one GNSS fix. The UE may transmit an uplink transmission with a timing advance based on the adjusted self-estimated delay and a cumulative timing advance value based on the one or more timing advance commands from the NTN.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a beam failure recovery (BFR) message regarding a failed link, wherein the failed link is one of an indirect link with a network node via a relay node or a direct link with the network node, wherein the BFR message is transmitted on one of the indirect link or the direct link that is not the failed link. The UE may receive an updated beam configuration for the failed link on a selected beam indicated by the BFR message. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit downlink control information (DCI) to a user equipment (UE) indicating a joint field for at least a first component carrier (CC) and a second CC of a carrier aggregation configuration. For example, the joint field may include a rate matching (RM) indication for the first CC and the second CC, a zero power channel state information reference signal (ZP-CSI-RS) indication for the first CC and the second CC, or both. In some cases, the RM indication may include a common RM resource (RMR) configuration applicable for both the first CC and the second CC or per-CC RMR configurations that indicate separate RMRs for each of the CCs. Additionally, the ZP-CSI-RS indication may include a set identifier that indicates a resource set for ZP-CSI-RS resources for both the first CC and the second CC.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may transmit an expiration indication to a receiving device as part of a scheduling message for a transport block. The expiration indication may provide information related to an expiration time for the transport block. If the expiration time is reached prior to successful reception by a receiving device, the receiving device may assume that the transport block has expired and may refrain from transmitting a retransmission grant, or may empty a hybrid automatic repeat request (HARQ) buffer associated with the transport block. If the transmitting device fails to successfully receive an indication from the receiving device of a successful reception of the transport block prior to the expiration period, the transmitting device may also assume that the transport block has expired.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may employ one or more scheduling constraints to support efficient utilization of techniques for intra-device handling of overlapping scheduled uplink transmissions (e.g., intra-device dynamic resource cancelation and multiplexing) as well as inter-device handling of overlapping scheduled uplink transmissions (e.g., inter-device dynamic resource cancelation and multiplexing). Scheduling constraints may define how a device may apply intra-device and inter-device multiplexing and cancelation rules for various scenarios. For example, a device may apply intra-UE cancelation rules before inter-device cancelation rules. In some examples, later-received grants or uplink preemption indications (ULPIs) may not change a device's previously established decision to drop an uplink transmission. As another example, a device may not expect to receive a grant for an uplink transmission that would arise in subsequent cancelation of that uplink transmission due to a previously-received grant or previously-received ULPI.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may accumulate a number of hybrid automatic repeat request (HARQ) bits as a result of one or more resource conflicts and may store the number of HARQ bits for a later transmission opportunity. The UE may transmit a scheduling request that requests resources for a transmission of the number of HARQ bits that are stored at the UE as a result of the number of HARQ bits satisfying a triggering condition. For example, the UE may transmit the scheduling request if a quantity of the number of HARQ bits satisfies a threshold quantity. Additionally or alternatively, the UE may transmit the scheduling request if the number of HARQ bits include triggering content. For example, the UE may transmit the scheduling request if any HARQ bit stored at the UE conveys a negative acknowledgement (NACK).
