Abstract: A configuration to allow a UE to transmit or receive control information on a downlink or uplink channel that is mapped to specific layers. The apparatus receives, from a base station, a first DCI on a PDCCH. The apparatus receives, from the base station, a second DCI on a PDSCH. The first DCI schedules the transmission of the PDSCH having the second DCI. The apparatus receives a configuration for a scheduled uplink or downlink transmission based on the second DCI. The second DCI is associated with a layer of the PDSCH having the second DCI having a lowest DMRS port ID.

Abstract: A non-terrestrial network is provided that includes a satellite that transmits an orbital parameter message to a user equipment. The user equipment processes the orbital parameter message to determine a current range from the user equipment to the satellite based upon the received orbital parameter message, a timing offset and a frequency offset for an uplink transmission to the satellite.

Abstract: Disclosed are techniques for positioning. A receiver measures a time of arrival (ToA) of a positioning reference signal (PRS) transmission of a first PRS sequence transmitted by a first transmitter, measures a ToA of a PRS transmission of a second PRS sequence transmitted by a second transmitter, and determines an observed time difference of arrival (OTDOA) as a difference between the ToA of the PRS transmission of the first PRS sequence and the ToA of the PRS transmission of the second PRS sequence, wherein the OTDOA is less than half a maximum differential delay expected between the PRS transmission of the first PRS sequence and the PRS transmission of the second PRS sequence, and wherein a repetition duration of the first PRS sequence and the second PRS sequence is greater than 10 milliseconds (ms) and at least twice the maximum differential delay.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station by initiating a random access procedure with a two-root preamble. The UE may receive, from the base station, control signaling that indicates a set of root preamble sequences. The UE may transmit, to the base station, a preamble signal that is generated based on a first root preamble sequence and a second root preamble sequence of the set of root preamble sequences. The UE may then monitor for a preamble response based on the preamble signal. In some cases, the base station may be a base station in a terrestrial network. In other cases, the base station may be a satellite in a non-terrestrial network (NTN).

Abstract: Various aspects of the disclosure relate to allocating control signaling resources for multiple carrier scenarios. In an example implementation, N-to-1 mapping is used between forward link control signaling resource allocation indices (e.g., control channel elements) and return link control signaling resources (e.g., for ACK/NACK signaling) indices in each return link component carrier. A collision between forward link control signaling assignments for different user terminals (UTs) may occur when UT-specific search spaces overlap each other. Such a collision may be avoided, for example, by scheduling different UTs on different return link component carriers, scheduling return link grants instead of forward link grants, or scheduling a different forward link control signaling candidate that is associated with a different forward link control signaling resource allocation index.

Abstract: A method and apparatus for operating a controller for a satellite communications system during inter-beam handovers. In some aspects, the controller may perform an inter-beam handover by switching communications with a user terminal from a first beam to a second beam of a satellite. The controller receives a feedback message form the user terminal, via the first beam, after the inter-beam handover is completed, and may then selectively retransmit data to the user terminal via the second beam based at least in part on the feedback message.

Abstract: A non-geosynchronous satellite system, where each satellite has an antenna (perhaps a multi-element antenna) to form a beam pattern comprising a set of beams in the footprint of the satellite, where in one implementation each beam is substantially elliptical in shape having a minor axis and a major axis, where the minor axes are substantially collinear and the major axes are substantially oriented east to west. For a satellite, power is reduced or turned off for a subset of the set of beams, wherein each beam in the subset is reduced at or below a corresponding power level such that when a beam is powered above its corresponding power level an equivalent power flux-density (EPFD) exceeds a limit at some point on the Earth's surface.

Abstract: In a disclosed embodiment, signal levels of the active sectors of an access terminal are compared with the signal level of the current serving sector of the access terminal (204). Next, a delta credit is accumulated (206). If a DRC lock bit is available, then an accumulated total credit is authorized to produce an authorized accumulated total credit (208), (210). Afterwards, a new serving sector is identified from a pool of candidate sectors based on the signal levels of the active sectors and the authorized accumulated total credits (212).

Abstract: A UE may identify a first set of preserved resources of one or more sets of preserved resources. An aircraft-borne device may identify a first set of preserved resources of one or more sets of preserved resources. The first set of preserved resources may be associated with a time domain starting point, a time domain duration, and a frequency domain resource allocation. The UE may transmit, to an aircraft-borne device and the aircraft-borne device may, receive from the UE, over at least part of the first set of preserved resources, a synchronization signal and a first payload message. The first payload message may include a first emergency message and may be transmitted and received via one of a first PUSCH, a first PSSCH, or a PSCCH. The aircraft-borne device may forward, to a base station or another aircraft-borne device, at least the first emergency message.
