Abstract: Apparatuses and methods for altitude-dependent measurement and reporting configurations are described. An apparatus is configured to receive, from a network node, a measurement object configuration, where the measurement object configuration indicates at least one altitude parameter associated with a set of SSBs. The apparatus is also configured to measure a SSB value for each SSB in the set of SSBs based on the measurement object configuration and an altitude of the UE. An additional apparatus is configured to configure, for a UE, a measurement object configuration, where the measurement object configuration indicates at least one altitude parameter associated with a set of SSBs. The additional apparatus is also configured to provide the set of SSBs indicated in the measurement object configuration.

Abstract: In a user equipment (UE) of a wireless communication network, the UE configured to operate in half duplex frequency division duplexing (HD-FDD) mode in the network the UE configures for one or more conditions under which the UE will transmit under HD-FDD mode in uplink (UL) to the network and not receive in downlink (DL) from the network during a Random Access Channel (RACH) procedure. The UE determines whether the configured one or more conditions obtain for a particular RACH procedure. Upon determining that the configured one or more conditions obtain for the particular RACH procedure, the UE transmits under HD-FDD mode in UL during the particular RACH procedure in accordance with the configured one or more conditions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive radio resource control (RRC) signaling that indicates (e.g., schedules, configures) resources for a set of physical uplink control channel (PUSCH) transmission occasions, each of the PUSCH transmission occasions configured with a capacity for transmission of a maximum quantity of transport blocks (TBs), the maximum quantity including two or more TBs. The UE may generate a PUSCH message in accordance with the RRC signaling, where the PUSCH message includes one or more TBs, the one or more TBs being less than the maximum quantity of TBs, and may transmit the PUSCH message within a PUSCH transmission occasion of the set of PUSCH transmission occasions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) including a transmission configuration indicator (TCI) field with a value, the value mapping to a set of TCI states for a set of co-scheduled cells. The UE may communicate on the set of co-scheduled cells using the set of TCI states associated with the value of the TCI field. Numerous other aspects are described.

Abstract: To facilitate operations of a low-power UE with high RF sensitivity, methods, apparatuses, and computer-readable medium are provided. An example method includes receiving, from a base station or a second UE, a reservation reserving a set of time-domain resources and a set of frequency domain resources around a WUS for a low-power UE. The example method further includes refraining from transmitting in the reserved resources.

Abstract: Non-terrestrial networks (NTNs) may establish uplink (UL) and downlink (DL) radio frame timing structures to efficiently account for propagation delay and propagation delay variation associated with communications in the NTN. NTNs may manage (synchronize) radio frame timing structures of base stations (e.g., satellites) and user equipment (UEs) in the NTN. Further, UEs may determine timing advance (TA) values to be applied to UL transmissions based on their respective scheduling offset (e.g., offset in UL and DL radio frame timing structures), as well as based on propagation delay or round trip time (RTT). As such, served UEs may determine UL timing such that UL transmissions from the UEs to a satellite arrives at the satellite in a time synchronized manner. In other cases, a satellite may determine UL timing, based on reception timing, such that various UEs in the NTN may implement uniform UL and DL radio frame timing structures.

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.
