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: Methods, systems, and devices for wireless communications are described that provide for measurement of reference signals by an aerial user equipment (UE), and reporting of the measurements to a serving base station. An aerial UE may initiate one or more measurements based on one or more height thresholds, and may transmit measurement reports that provide an indication of height along with measured parameters. An aerial UE may also provide an indication of a number of other aerial UEs or other aerial vehicles that are detected within a vicinity of the aerial UE, Reports of measurements (e.g., reference signal received power (RSRP) measurements) by multiple UEs for multiple different locations and heights may be used to determine coverage maps and/or drone density maps for multiple different heights or altitudes.

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: A method for wireless communication by a wireless device includes receiving a first bit sequence and a second bit sequence from an upper layer of a wireless communication protocol stack. The first bit sequence is assigned a first class and the second bit sequence is assigned a second class. The second bit sequence is included in a same medium access control (MAC) packet data unit (PDU) as the first bit sequence. The method also includes processing, at a physical layer, the first bit sequence with a first quality of service (QoS) level, and the second bit sequence with a second QoS level that is different from the first QoS level.

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.
