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: In some aspects, a user equipment (UE) may receive, via a first radio access technology (RAT), system information that identifies a set of frequencies of a second RAT and one or more available multicast or broadcast (MB) services. The UE may trigger a switch from a first multicast radio bearer (MRB), of the first RAT, to a first unicast dedicated radio bearer (DRB), of the first RAT, for reception of an MB service via the first RAT. The UE may transmit an indication that indicates the MB service or a frequency via which the MB service is available via the second RAT. The UE may receive an MRB configuration associated with receiving the MB service via a target base station using the second RAT. The UE may switch from a second unicast DRB, of the second RAT, to a second MRB, of the second RAT, after handover.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform one or more measurements associated with an altitude of the UE. The UE may obtain an indication of an antenna condition or a flight path condition associated with the UE. The UE may transmit, based at least in part on the altitude of the UE being greater than an altitude threshold and at least one of the antenna condition or the flight path condition being satisfied, a measurement report that includes an indication of at least one of a location of the UE or a velocity of the UE. 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.

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: Method and apparatus for an RRC reestablishment procedure between a TN and an NTN. The apparatus may be on a first network associated with one of the TN or the NTN. The apparatus transmits a RRC connection request to establish a connection with a second network associated with one of the NTN or the TN. The apparatus receives an RRC reconnection message from a network entity associated with the second network. The apparatus transmits an RRC reconnection complete message to the network entity associated with one of the NTN or the TN of the second network. The apparatus may transmit a registration update request to the network entity associated with one of the NTN or the TN of the second network.
