Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information indicating whether hybrid automatic repeat request (HARQ) feedback is disabled for one or more HARQ processes. The UE may receive a downlink communication. The downlink communication may include a HARQ process identifier that indicates a HARQ process to be used for the downlink communication. The UE may selectively provide HARQ feedback for the downlink communication based at least in part on the HARQ identifier and information indicating whether HARQ feedback is disabled for the HARQ process. Numerous other aspects are provided.

Disabling hybrid automatic repeat request feedback

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a default value for a radio parameter used for communicating with a network node based at least in part on whether the network node is a terrestrial network (TN) node or a non-terrestrial network (NTN) node, an orbit type associated with the network node, or a coverage type associated with the network node. The UE may transmit a communication, e.g., to the network node based at least in part on the default value for the radio parameter. Numerous other aspects are described.

Non-terrestrial network default value configuration

Certain aspects of the present disclosure provide techniques for indicating a user equipment (UE) preferred paging carrier. According to certain aspects, a method for wireless communications by a UE generally includes generating a cell measurement report, transmitting the cell measurement report to a network entity, transmitting, to the network entity, an indicator of a preferred paging carrier, and monitoring paging occasions (POs) in at least the preferred paging carrier.

Indication of preferred paging carrier

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity and via a system information block (SIB), information that indicates frequencies associated with a terrestrial network (TN) cell. The information may include one or more of a priority of frequency, frequency-specific offset, or cell-specific offset. The UE may perform, during an idle mode of the UE, measurements of the frequencies associated with the TN cell based at least in part on a location of the UE being within the TN cell. Numerous other aspects are described.

Performing measurements of frequencies associated with terrestrial network cells

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive first control signaling indicating a configuration associated with a target network node in a non-terrestrial network. The configuration may include a first UE-group configuration and a UE-specific configuration including integrity information for the first UE-group configuration. The UE may perform a connection operation based on a trust status of the first UE-group configuration.

Managing group configurations in wireless communications systems

A base-station (BS) receiving a random access request from user equipment (a UE), followed by a connection request. The connection request contains UE identity information which may have one of multiple formats depending on whether the access request and/or the connection request indicate that the UE is operating as a bandwidth-limited (BL) UE, an enhanced coverage (CE) UE, or a UE that operates in neither the BL mode nor the CE mode. In the BL mode, the UE may transmit a truncated identifier that is sufficient for the BS to retrieve capability information for the UE prior to transmitting a resource grant to the UE. The BS may then configure the UE and BS to using a radio configuration optimized for the UE's capabilities and transmit the resource grant in accordance with the optimized configuration.

Truncated identification indicators for early user equipment (UE) capability retrieval

Certain aspects of the present disclosure are directed to techniques for hybrid automatic repeat request (HARQ) codebook design. For example, a user equipment (UE) configured for feedback processing may comprise a memory and a processor configured to receive, from a base station (BS), a first indication of a first feedback process type for providing feedback to the BS for a plurality of feedback processes of the UE. The memory and the processor may also be configured to receive one or more first downlink transmissions from the BS associated with at least one feedback process of the plurality of feedback processes. The memory and the processor may also be configured to transmit feedback or withhold transmission of feedback to the BS regarding decoding of the one or more first downlink transmissions according to the first feedback process type.

Hybrid automatic repeat request (HARQ) codebook design

Certain aspects of the present disclosure provide a method of wireless communication by a user equipment (UE). The method generally includes performing a mobility procedure to establish a connection in a target radio access technology (RAT) while maintaining a context established in a source RAT, wherein one of the source RAT or target RAT is a terrestrial network (TN) RAT and the other is a non-terrestrial network (NTN) RAT and sending a tracking area update (TAU) request after establishing the connection in the target RAT.

Handover between terrestrial network and nonterrestrial network

Aspects described herein relate to receiving an update value for a timing advance of a satellite link between the UE and a base station, computing, based on the update value for the timing advance, a portion of a timing difference between the update value and a previous value for the timing advance of the satellite link that is corrected by closed loop timing advance control from the base station, computing, based at least in part on computing the portion, a total value for the timing advance of the satellite link, and applying, at the UE and based at least in part on the total value for the timing advance of the satellite link and the closed loop timing advance control, an applied timing advance for communicating with the base station.

Techniques for controlling timing of wireless communications devices in non-terrestrial networks

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an entity of a non-terrestrial network (NTN), a system information block (SIB) that indicates information relating to one or more NTN SIBs that are to include at least one of ephemeris information or feeder link timing advance information. The UE may receive, from the entity of the NTN, the one or more NTN SIBs based at least in part on the information. Numerous other aspects are described.

A method of wireless communication performs a public land mobile network (PLMN) search for a higher priority PLMN. The PLMN search includes a candidate PLMN having a different mobile country code (MCC) than a serving PLMN. The method switches to the higher priority PLMN when the PLMN search locates the higher priority PLMN. A method determines whether a user equipment (UE) has transitioned between an international area and a national area. The method triggers PLMN selection in response to the UE having transitioned between the international area and the national area.

Wireless network selection in international areas

A user equipment (UE) selects or reselects a target cell of a non-terrestrial network or resumes connectivity with the target cell after a satellite handover for a permanently fixed low Earth orbit (LEO) cell. The target cell is a serving or non-serving cell. The UE determines a cell type of the target cell. The cell type may be a LEO cell type, a geostationary Earth orbit (GEO) cell type, a moving cell type, a fixed cell type, a temporarily fixed LEO cell type, or a permanently fixed LEO cell type. The UE completes selection or reselection of the target cell or completes the connectivity with the target cell, based on the cell type.
