Abstract: A UE may transmit a message comprising information regarding one or more physical random access channel (PRACH) capabilities of the UE to a base station (BS). The UE may then receive, from the BS, signaling comprising an indication of one or more configured PRACH formats supporting the one or more PRACH capabilities. Next, the UE may transmit, using the one or more configured PRACH formats, one or more preambles to the BS in a random access (RACH) procedure. Accordingly, the UE may receive a random access response (RAR) from the base station and further, in response to receiving the RAR, establish a connection with the BS.

Abstract: Systems and methods for implementing uplink (UL) gaps to facilitate user equipment (UE) calibration are disclosed herein. A UE determines one or more slot patterns of a slot configuration that is repeated during time division duplex (TDD) communication with a base station. The UE determines a UL gap periodicity (defining periods covering an integer number of repetitions of the slot configuration). The UE then performs UE calibration during one or more semi-persistently configured UL slots of a period of the UL gap periodicity that correspond to UL indication(s) in one or more of a common configuration, a dedicated configuration, and/or a slot format indication (SFI) downlink control information (DCI) for the slot pattern(s) of the slot configuration. Methods of identifying particular semi-persistently configured UL slots of a period to use for the UL gap are also discussed. UL slot indications from dynamic DCI are not used for UL gap purposes.

Abstract: Techniques discussed herein may better ensure proper timing and synchronization of transmissions within a wireless communications network that includes a terrestrial network and a non-terrestrial network (NTN). A user equipment (UE) may maintain (e.g., determine and update on an ongoing basis) a timing advance (TA) value that the UE may apply to uplink (UL) transmissions to account for propagation delays, including changes in propagation delays, between the UE, NTN, and terrestrial network. TA maintenance may be based on network broadcasts, random access channel (RACH) procedures, control messages, timing drift rates (e.g., of the UE or NTN satellite), beam switching, and more.

Abstract: The present application relates to devices and components including apparatus, systems, and methods for triggering and using uplink gaps in cellular networks. A method of an embodiment comprises: transmitting, to a base station, an indication of an uplink (UL) gap capability or preference of the UE for body proximity sensing (BPS) or transceiver calibration; activating a UL gap configuration based on an activation command received from a network; and performing operations for BPS or transceiver calibration within a UL gap defined by the UL gap configuration.

Abstract: Aspects are presented herein of apparatuses, systems, and methods for measurement gap configuration. A cellular network may establish communication with a UE using a first and second cell. The cellular network may configure bandwidth parts (BWPs) for the first and second cell, including a first and second BWP for the first cell and a third and fourth BWP for the second cell. A measurement gap configuration that specifies when the UE is to use a first measurement gap pattern may be provided to the UE. At a first time, the cellular network may communicate with the UE using the first BWP for the first cell and the third BWP for the second cell, based on the first measurement gap pattern. At a second time, the cellular network may communicate with the UE using the second BWP for the first cell based on a modification of the first measurement gap pattern.
