Abstract: Certain aspects of the present disclosure provide techniques for providing feedback. For example, a user equipment (UE) may receive, from a network node, a configuration of a search space comprising time and frequency resources available to the network node for communicating a downlink control channel, the configuration indicating a feedback process type corresponding to the search space. The UE may also receive, from the network node, the downlink control channel in the search space. The UE may also receive a downlink transmission scheduled by the downlink control channel. The UE may selectively provide feedback to the network node regarding decoding of the downlink transmission according to the feedback process type corresponding to the search space.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a duration of a first gap that precedes a reference signal, based at least in part on a polarization of the reference signal. The UE may determine a duration of a second gap that succeeds the reference signal, based at least in part on the polarization of the reference signal. The UE may perform a measurement of the reference signal based at least in part on the first gap and the second gap. Numerous other aspects are provided.

Abstract: 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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an offset associated with a propagation delay in a network, wherein hybrid automatic repeat request (HARQ) feedback is enabled at the UE, and may monitor for a retransmission of a downlink communication in the network according to the offset. In some aspects, a UE may start a timer associated with monitoring for a retransmission of a downlink communication in a network, wherein HARQ feedback is disabled at the UE, and may monitoring for the retransmission of the downlink communication after starting the timer or after expiration of the timer. Numerous other aspects are provided.

Abstract: Some techniques and apparatuses described herein enable a user equipment (UE) to autonomously modify one or more transmission parameters, other than a transmit power, for uplink communications after detecting a change in pathloss. The UE may modify the one or more transmission parameters without receiving instructions from a base station, such as in downlink control information, with updated value(s) for the one or more transmission parameters. As a result, the UE and the base station avoid the round trip delay that would otherwise be required to modify the transmission parameter(s) and perform link adaptation. Some techniques and apparatuses described herein apply to non-terrestrial networks with a large round trip delay. Other aspects are described.

Abstract: Various aspects relate to adjusting communication timing in response to a switch from one feeder link to another feeder link in a non-terrestrial network. For example, when a satellite moves out of the coverage area of a first ground network entity (or if the first ground network entity is turned off), the satellite switches to a second ground network entity. The resulting switch from a first feeder link for the first ground network entity to a second feeder link for the second ground network entity may cause a timing glitch that adversely affects the UEs under the coverage of the satellite. The disclosure relates in some aspects to sending an indication of the switch and/or a common timing adjust command to all of the UEs affected by the feeder link switch.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may account for the application of orthogonal cover coding (OCC) to an uplink transmission when determining the transport block size (TBS) for the uplink transmission. OCC may be used to multiplex transmissions from multiple UEs and may involve spreading information. Described techniques may involve accounting for the spreading of information bits when determining the TBS for the uplink transmission to which OCC is applied. Sub-physical resource block (sub-PRB) frequency allocations may be provided for uplink transmissions. The UE may account for the allocated quantity of sub-carriers when determining the quantity of information bits. To indicate a sub-PRB, the UE may be configured to reinterpret one or more fields of an existing downlink control information (DCI) format as indicating the allocated sub-carriers, or a new DCI format may be configured that includes fields for indicating a sub-PRB allocation.

Abstract: Techniques are disclosed for coverage-aware joint configuration for multi-network wireless communication. The techniques can include identifying a travel route for travel of a user equipment (UE) from a start location to a destination location, obtaining multi-network wireless coverage information for the travel route, wherein the multi-network wireless coverage information includes terrestrial network (TN) wireless coverage information and non-terrestrial network (NTN) wireless coverage information, determining a joint TN/NTN wireless communication configuration for the UE for the travel route based on the multi-network wireless coverage information, and sending the joint TN/NTN wireless communication configuration to the UE.

Abstract: A user equipment (UE) may transmit a first message comprising a first indication associated with a timing advance command (TAC) granularity. A network node may receive the first message. The network node may transmit a second message comprising a TAC configuration associated with the TAC granularity based on the first indication. The network node may transmit the second message in response to receiving the first message. The UE may receive the second message. The network node may transmit a TAC. The UE may receive the TAC. The UE may transmit a third message based on the TAC configuration. The UE may transmit the third message in response to receiving the TAC. The network node may receive the third message. The network node may be a non-terrestrial network node, such as a satellite or a low-Earth orbit device.
