Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may obtain, at an access stratum (AS) layer, an indication of an inter-satellite link (ISL) activation that is to take place at an activation time. The wireless communication device may receive communications. The wireless communication device may buffer the communications in a buffer at the AS layer. The wireless communication device may release the communications from the buffer to an upper protocol layer at a rate of release that is to change between a transition start time and the activation time. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for random access. A method for wireless communications by a user equipment (UE) includes determining a first timing advance (TA) for transmitting a random access channel (RACH) preamble. The method includes determining a second TA, different than the first TA, for transmitting the RACH preamble. The method includes transmitting the RACH preamble using the second TA. The method includes receiving a random access response (RAR) message including a timing advance command (TAC) and determining whether the RAR is intended for the UE based on the TAC, the first TA, and the second TA. The method includes transmitting a physical uplink shared channel (PUSCH) transmission based on a determination that the RAR is intended for the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate with a non-terrestrial network entity using a radio configuration over a service link. The UE may receive an indication of a topology change event that is to occur in association with an inter-satellite link. The UE may communicate, after the topology change event, using at least part of the radio configuration over the service link. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for compensating for certain characteristic(s) of an intelligent reflecting surface (IRS). A method that may be performed by a first wireless node includes obtaining an indication of a correction for an IRS to compensate for one or more characteristics of the IRS and communicating with a second wireless node via the IRS using the indication of the correction.

Abstract: Certain aspects of the present disclosure provide techniques for communicating with an ad hoc intelligent reflecting surface (IRS). A method that may be performed by a user equipment includes receiving signals from a network entity via an ad hoc IRS; configuring the IRS for communications between the UE and the network entity based at least in part on the received signals; and communicating with the network entity through the IRS.

Abstract: Methods, apparatuses, and computer-readable medium for fronthaul compression are provided. An example method may include receiving, from a UE, uplink data via one or more active tones of a plurality of tones in a symbol, the uplink data corresponding to an access vector. The example method may further include compressing the uplink data based on a linear transformation of a pseudo-access vector generated based on the access vector, the linear transformation including a matrix, the compression enabling a second network entity to decompress the compressed uplink data without knowing one or more locations associated with the one or more active tones. The example method may further include transmitting, to the second network entity, the compressed uplink data.

Abstract: A node may forward, from a base station to a first UE, or from the first UE to the base station, one or more wireless signals. The node may identify an indication to stop signal forwarding to the first UE. The indication may be based on a level of an interference to a second UE associated with the signal forwarding to the first UE being greater than a first threshold. The level of the interference to the second UE may be based on a path gain difference or a signal strength at the first UE associated with the signal forwarding to the first UE. The signal strength at the first UE associated with the signal forwarding to the first UE may correspond to an RSRP at the first UE. The node may stop the signal forwarding to the first UE based on the indication.

Abstract: A node may identify a node configuration including one or more surface phase configurations associated with the node. In one configuration, the node may receive, from the base station, an indication of the node configuration. In another configuration, the node may select, at a controller associated with the node, the node configuration. The one or more surface phase configurations may be based on a wavelength corresponding to a center of a BWP associated with the one or more wireless signals or a wavelength corresponding to a center of a resource allocation associated with the one or more wireless signals. The node may forward, from a base station to a UE, or from the UE to the base station, one or more wireless signals. The forwarded one or more wireless signals may be associated with a beam squint less than a first threshold.

Abstract: A UE determines a group identifier based at least in part on a timing advance (TA) associated with the UE, the group identifier associated with at least the UE and a second UE and receives a sidelink resource allocation associated with the group identifier. The UE transmits sidelink communication using the sidelink resource allocation. A network node associates a UE with a group identifier based on a timing advance (TA) associated with the UE and transmits a sidelink resource allocation associated with the group identifier, the group identifier associated with at least the UE and a second UE.
