Abstract: A user equipment (UE) receives one or more timing advance commands from a non-terrestrial network (NTN). The UE resets, after a GNSS fix, a cumulative timing advance value based on the one or more timing advance commands from the NTN and transmits an uplink transmission with a timing advance based on a self-estimated delay and the cumulative timing advance value. The UE may adjust a self-estimated delay based on at least one GNSS fix. The UE may transmit an uplink transmission with a timing advance based on the adjusted self-estimated delay and a cumulative timing advance value based on the one or more timing advance commands from the NTN.

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: RACH occasion repetition and PRACH format selection in an NTN are disclosed. The base station may determine, based on at least one beam, a first PRACH configuration for at least one first UE and a second PRACH configuration for at least one second UE. The base station may transmit, to at least one of the at least one first UE or the at least one second UE, an indication of the first PRACH configuration and the second PRACH configuration. The UE, based on whether it is a first UE or a second UE, may select, based on the received indication, the first PRACH configuration or the second PRACH configuration for at least one beam. The UE may initiate, via the at least one beam, a RACH procedure for the selected first PRACH configuration or the selected second PRACH configuration.

Abstract: Disclosed are techniques for location verification. In an aspect, a radio access network (RAN) node receives a request from a core network node to verify a location of a user equipment (UE), performs a RAN-based positioning procedure with the UE to determine a verified location of the UE, and transmits a response to the core network node, the response including: measurements obtained by the UE during the RAN-based positioning procedure, measurements obtained by the RAN node during the RAN-based positioning procedure, the verified location of the UE, an indication that the location of the UE is verified, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a duty cycle function corresponding to a duty cycle range. In some cases, the UE may determine the duty cycle function based on a congestion metric. The UE may identify a bandwidth allocation for the UE and may determine a duty cycle within the duty cycle range based on the duty cycle function and the bandwidth allocation. In some cases, the UE may identify one or more of the duty cycle function, the congestion metric, the duty cycle range, or the bandwidth allocation based on control signaling from a base station. The UE may transmit a packet within the bandwidth allocation in accordance with the duty cycle.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify time and frequency resources for a physical downlink shared channel (PDSCH) to be transmitted to a user equipment (UE) in a first transmission time interval (TTI). The base station may transmit configuration information for a control channel search space set in a second TTI. The second TTI may precede the first TTI. The configuration information may include an indication of an absence of a physical downlink control channel (PDCCH) transmission to send in the control channel search space set indicating the identified time and frequency resources for the PDSCH, and a set of time and frequency resources for the control channel search space set. The UE may receive the configuration information and identify the time and frequency resources allocated for the PDSCH in the second TTI, and receive the PDSCH transmission in the second TTI.
