Abstract: Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may identify at least one scheduling offset associated with a propagation delay between a base station of a NTN and the UE. The apparatus may also select a first scheduling offset of the at least one scheduling offset associated with the propagation delay between the base station and the UE. Additionally, the apparatus may transmit, to the base station, an uplink transmission based on the first scheduling offset, the uplink transmission being associated with a PUSCH, a PUCCH, or a PRACH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source base station, configuration information for a handover, wherein the configuration information indicates, for a target non-terrestrial cell, timing and synchronization parameters including a scheduling timing offset, a round trip time between a reference point and a target base station associated with the target non-terrestrial cell, satellite ephemeris information, an ephemeris validity duration associated with the satellite ephemeris information, common timing advance parameters, and a common timing advance validity duration associated with the common timing advance parameters. The UE may perform the handover with the target base station associated with the target non-terrestrial cell based at least in part on the timing and synchronization parameters for the target non-terrestrial cell. Numerous other aspects are described.

The apparatus transmits a RRC connection request to establish a connection with a second network associated with one of the NTN or the TN. The apparatus receives an RRC reconnection message from a network entity associated with the second network. The apparatus transmits an RRC reconnection complete message to the network entity associated with one of the NTN or the TN of the second network. The apparatus may transmit a registration update request to the network entity associated with one of the NTN or the TN of the second network.

Abstract: Certain aspects of the present disclosure provide techniques for data collection for non-terrestrial networks (NTN). One aspect provides a method for wireless communications by a user equipment (UE). The method generally includes transmitting an indication of a capability of the UE to connect to a network via both terrestrial network (TN) cells and non-terrestrial network (NTN) cells and transmitting one or more data collection reports in accordance with the indicated capability.

Abstract: A receiver receives a first message including a first PDCP SN. The receiver may receive a second message including a second PDCP SN. The receiver may derive a second RTP SN based on at least one of a first RTP SN of the first message, the first PDCP SN, the second PDCP SN, or an RTP SN field of a second PDCP header composing the second message.

Abstract: Methods, systems, and devices for wireless communications are described. A network may be configured to provide a beam measurement configuration to a UE that indicates durations for monitoring transmission beams, and tuning a component of the UE between the monitoring. The durations may include a first portion that a UE may use for a tuning operation and a second portion that the UE may use to monitor for or measure a respective reference signal. In various examples, the indicated durations may include a third portion that the UE may use for another tuning operation, or the durations may overlap with one another during an overlap duration that the UE may use for another tuning operation. During the indicated durations, the network may refrain from transmitting other downlink data or control information for the UE, and the UE may refrain from monitoring for such other downlink data or control information.

CPC classification number: H04W72/21
Abstract: An apparatus for wireless communications includes a processor, and a memory coupled with the processor and storing instructions operable, when executed by the processor, to cause the apparatus to output a pre-configured uplink resource (PUR) configuration information comprising a least significant bit (LSB) associated with a hyper system frame number (H-SFN). Execution of the instructions further cause the apparatus to obtain, from a user equipment (UE) at a PUR start time, a first message on a PUR associated with the PUR configuration information, the PUR start time associated with the H-SFN corresponding to the LSB.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may start a timer after a repetition of a communication, where calculation of a length of the timer includes an offset that corresponds to a propagation delay between the UE and a base station via a non-terrestrial network (NTN) entity. The UE may start a discontinuous reception (DRX) retransmission timer after expiration of the timer. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may use enhanced techniques for determining whether a transmission is scheduled to include new data when a mode for reporting acknowledgment feedback is disabled for one or more hybrid automatic repeat request (HARQ) processes used by the receiving device. An enhanced technique may include increasing a quantity of bits used to convey an indication of whether a scheduled data transmission includes new data. An enhanced technique may include monitoring a duration between transmissions scheduled by different control messages based on a timing parameter that indicates a maximum time between transmissions of a data set and corresponding transmission including the data set.
