Abstract: Methods, systems, and devices for wireless communications are described. A satellite may determine one or more sets set of resources for conveying reference signals to a user terminal. In one example, the satellite may determine a set of resources that includes multiple resource groups each associated with a respective frequency range. In another example, the satellite may determine multiples sets of resources and each set of resources may include resources within respective frequency range. Upon determining the set(s) of resources, the satellite may transmit an indication of the set(s) of resources to a user terminal.

Abstract: Apparatus, methods, and computer-readable media for indicating repetition for messages without relying on RRC signaling are disclosed herein. An example method for wireless communication at a UE includes receiving, before performing an RRC configuration procedure or an RRC reconfiguration procedure, a first communication scheduling a first data transmission with associated feedback. The first communication may include first information associated with the first data transmission and a first redundancy version indicator (rv Index). The example method also includes attempting to receive the first data transmission based on the first information. The example method also includes transmitting, based on the first rv Index, a first quantity of repetitions of first data feedback for the first data transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a downlink communication that indicates a random access response (RAR) or a fallback RAR, the downlink communication being received during a contention-free random access (CFRA) involving the UE and the network node. The UE may transmit, to the network node and based at least in part on an uplink grant in the RAR or in the fallback RAR, an uplink transmission with a repetition, the uplink transmission with the repetition being transmitted during the CFRA involving the UE and the network node. Numerous other aspects are described.

Abstract: Aspects are provided for enhancing a physical uplink control channel PUCCH) with frequency hopping for PUCCH repetition prior to dedicated PUCCH resource configuration. For example, the PUCCH may carry a HARQ ACK for Message 4 or Message B. An apparatus such as a user equipment (UE) receives an indication that a cell supports an enhanced physical uplink control channel (PUCCH) frequency hopping pattern for PUCCH with repetition prior to dedicated PUCCH resource configuration. The UE indicates at least one of a capability or a request of the UE for the enhanced PUCCH frequency hopping pattern. The UE receives downlink control signaling that indicates whether the enhanced PUCCH frequency hopping pattern is configured. The UE transmits a PUCCH with repetition and frequency hopping based on whether the enhanced PUCCH frequency hopping pattern is configured.

Abstract: Aspects are provided for repeating a configuration for a transmission after contention resolution in an early contention resolution. An apparatus may be configured to obtain a configuration indicating a number of repetitions for a PUCCH transmission for a PDSCH prior to activation of a dedicated PUCCH resource configuration. The PUCCH transmission may include a HARQ feedback message after receiving a contention resolution message carried in a prior PDSCH in a random access procedure. The apparatus may also be configured to transmit the HARQ feedback message for the PDSCH on a PUCCH according to the number of repetitions. The apparatus may further be configured to transmit a subsequent HARQ feedback message for the PDSCH on the PUCCH according to the number of repetitions for the HARQ feedback message for the PDSCH on the PUCCH. This allows coverage techniques to be applied to certain transmissions in order to improve coverage and reliability.

Abstract: Aspects are provided for enhancing HARQ ACK for Message 4 or Message B. An apparatus may obtain a configuration indicating a number of repetitions for a physical uplink control channel (PUCCH) transmission in a plurality of slots prior to activation of a dedicated PUCCH resource configuration with a plurality of repetitions based on a radio resource control (RRC) message. The PUCCH transmission includes a Hybrid Automatic Repeat Request (HARQ) feedback message in response to receiving a message on a Physical Downlink Shared Channel (PDSCH) in a random access procedure. The PUCCH transmission may then be transmitted on a PUCCH according to the number of repetitions. This allows coverage techniques to be applied to certain transmissions in order to improve coverage and reliability. In an aspect, the coverage enhancement techniques may include repetition of a transmission for coverage extension.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, flight path information that indicates a planned flight path of the UE. The UE may receive, from the network node, timing advance compensation configuration information associated with the planned flight path of the UE and an indication of at least one application criterion associated with the timing advance compensation configuration information. The UE may transmit, to the network node, an uplink communication using a timing advance based at least in part on the timing advance compensation configuration information, in connection with a determination that the at least one application criterion is satisfied. Numerous other aspects are described.

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.
