Abstract: The disclosure relates in some aspects to enabling a user terminal (UT) to obtain information about nearby cells and any beams generated by nearby cells. For example, a network can send a neighbor cell list to UTs, where the list identifies the cells in that neighborhood and provides information about any beams generated by those cells. Thus, a UT can learn the neighboring beams/cells that the UT can reselect to if the current beam/cell becomes weak. In some aspects, the UE can learn the attitude (e.g., pitch, roll, yaw, or any combination thereof) profile of neighboring satellites as well as the pointing angles and the ON-OFF schedules of their beams. In some aspects, the UT can learn a start angle and a span for a satellite and use this information to identify a satellite the UT can reselect to if the current beam/cell becomes weak.

Abstract: A message may be too long to be sent all at once. For example, there may be a limit on the number of bits that can be transmitted by a device operating in a power-save mode. The disclosure relates in some aspects to sending a message over packet boundaries (e.g., several frames or sub-frames). The disclosure relates in some aspects to segmenting a Broadcast Information Block and sending the resulting segments over broadcast information window boundaries. In some aspects, this information may be sent via overhead channels. To facilitate this segmentation, information about the segmentation may be included in the information sent from the transmitter to the receiver. For example, a first segment may indicate the number of segments and subsequent segments may indicate the segment number.

Abstract: Certain aspects of the present disclosure provide techniques for sending a retransmission of codewords of a data packet to a receiver node, that were not previously successfully received by the receiver node, in a manner compatible with a receive capability constraint of the receiver node.

Abstract: Various aspects of the disclosure relate to managing ephemeris information. Provisions are made for providing ephemeris information to a user terminal (UT). Messages are defined for sending ephemeris information and for requesting ephemeris information. Ephemeris information for a subset of the satellites in a constellation may be sent to a UT to reduce signaling load. A UT may manage a database of ephemeris information to ensure freshness of the ephemeris information.
