Abstract: A UE may include IoT NTN device, and the UE may acquire the GNSS location to perform the time/frequency pre-compensation. A NAS layer of the UE may initiate a connection request procedure based on the GNSS fix procedure at one or more lower layer of the UE. A network may transmit a paging request to the UE, and manage a paging response timer based on the GNSS fix procedure at the UE.

Abstract: A wireless device may output a first message or a compression context message. The first message may include (a) a first payload associated with a first RTP-SN, (b) the first RTP SN, and (c) a first PDCP SN that is incrementally synchronized with the first RTP SN. The compression context message may include an indicator of compression context between the first RTP SN and the first PDCP SN. The wireless device may obtain a confirmation that a compression context between the first RTP SN and the first PDCP SN is established at a receiver. In response, the wireless device may output a second message. The second message may have a second payload associated with a second RTP SN and a second PDCP SN that is incrementally synchronized with the second RTP SN. The second message does not comprise a ROHC header having an RTP SN field.

Abstract: This disclosure provides systems, methods and apparatus for enabling multi-TRP transmission in non terrestrial networks. In one aspect, a user equipment receives a first reference signal from a first satellite transmission reception point (TRP) at a first timing and receives a second reference signal from a second satellite TRP at a second timing. The first timing is synchronized with the second timing at a first geographic location. The user equipment receives a third reference signal from the first satellite TRP at a third timing and receives a fourth reference signal from the second satellite TRP at a fourth timing. The third timing and the fourth timing are synchronized at the user equipment. The user equipment receives an indication of a timing offset of the fourth reference signal with respect to the second reference signal and uses the third and fourth reference signals as a quasi colocation (QCL) source.

Abstract: Certain aspects of the present disclosure provide techniques for signaling a scheduling offset for non-terrestrial networks (NTNs). In one aspect, a method for wireless communications by a user equipment (UE) includes receiving first signaling indicating a first part of a scheduling offset associated with a common timing advance (TA); receiving second signaling indicating a second part of the scheduling offset; and transmitting an uplink transmission based on the first and second parts of the scheduling offset.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a global navigation satellite system (GNSS) position associated with the UE, the GNSS position being associated with a GNSS validity timer. The UE may receive, in a connected mode, a closed loop command that is associated with a closed loop timer. The UE may perform an action based at least in part on an expiry of the GNSS validity timer and an expiry of the closed loop timer. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for a UE to select a public land mobile network (PLMN). In general, the present disclosure provides methods for PLMN scanning and selection of a PLMN with discontinuous coverage. In certain aspects, a UE may perform a PLMN scan according to a first schedule when a preferred PLMN of the UE is associated with discontinuous coverage (DC) and perform the PLMN scan according to a second schedule when the preferred PLMN of the UE is not associated with DC.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a trigger indicating that the UE is to perform a global navigation satellite system (GNSS) acquisition process within a GNSS measurement gap, wherein a start time of the GNSS measurement gap is based at least in part on whether hybrid automatic repeat request (HARQ) feedback is enabled for a channel in which the trigger is received. The UE may perform the GNSS acquisition process within the GNSS measurement gap based at least in part on the trigger. Numerous other aspects are described.
