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.

Neighbor cell list

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.

Receiver capability aware implementation of HARQ feedback

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.

Ephemeris information management for satellite communication

The disclosure relates in some aspects to forbidden area procedures and connection release management for a user terminal (UT). Forbidden area-related procedures include, for example, using a special paging area code (PAC) in conjunction with a forbidden area, defining a location reporting threshold for a UT based on the proximity of the UT to a forbidden area, or using a default paging area code if a service restriction for a UT has ended. Connection release management includes, for example, a UT sending a request to cause the release of a Radio Connection that the UT no longer needs, or a UT sending a Location Indication (e.g., including a flag requesting release of a connection) to release the connection used for location reporting when a UT is done sending the location information and is going to go back to idle mode.

Forbidden area procedures and connection release management

The disclosure relates in some aspects to managing paging area information for a user terminal (UT) and connection signaling. In some aspects, paging area information is provided for an idle UT by defining a default paging area code (PAC) that is known by the network and the UT. In some aspects, paging area information is communicated via connection signaling. In some aspects, connection signaling may be used to force a UT to invoke an update procedure (e.g., a reconnection).

Paging area procedures and connection signaling

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.

Dynamically segmenting information according to at least one criterion

The disclosure relates in some aspects to location reporting and paging for satellite communication. In one aspect, the disclosure relates to a user terminal (UT) sending a message to report information about the UT's location. A threshold may be used to control whether (e.g., when) the UT reports its location. The location information may be used to enforce area (e.g., country) restrictions for the UT. In one aspect, the disclosure relates to forwarding paging messages between network access controllers. For example, a network access controller that is not able to page a UT may forward a paging message to another network access controller. In one aspect, the disclosure relates to a list of paging areas that indicates where a UT need not perform a paging area update.

Wireless communication location reporting and paging

Methods, systems, and devices are described for wireless communication. A user equipment (UE), for example, may determine a content size of an uncompressed buffer and a content size of a compressed buffer. The UE may then generate a buffer status report (BSR) based on the content sizes of the uncompressed buffer and the compressed buffer. Alternatively, a base station may receive a BSR based on a size of an uncompressed buffer of the UE. The base station may then receive a compressed packet from the UE and may determine a compression gain based on a size of the compressed packet and a size of a corresponding uncompressed packet. The base station may then adjust the received BSR based on the compression gain.

Buffer status report for eDCS

Methods, systems, and devices are described for wireless communication at a UE. In aspects, a receiver may receive a transmission requesting information about support for data compression. The receiver may determine parameters related to the types of supported data compression and communicate the information to the transmitting device. In some cases, the receiver may then receive a message from the transmitting entity that requests establishment of a data compression configuration. The receiver may respond with confirmation or rejection of the proposed compression configuration. If the configuration is confirmed, the transmitter and receiver may exchange compressed data packets according to the configuration. The devices may exchange status and control information related to the compression configuration (e.g., in a compression header of a compressed message or a separate status and/or control information message).

Evolved data compression scheme signaling

Methods, systems, and devices are described for wireless communication at a device. A transmitting device such as a base station may select some packets for direct transmission to a receiving device using data compression based on the reliability of the direct connection. The transmitting device may select other packets for indirect transmission via an unreliable connection using uncompressed packets or compressed packets that will not be used to update a compression buffer. In some cases, uncompressed packets may also be sent via the reliable connection. If a packet sent over the unreliable connection is lost, it may be transmitted over the reliable connection.

Evolved data compression scheme for unreliable transmission modes

Satellite communication location reporting and paging

Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to enhanced compression formats for data compression (e.g., uplink data compression (UDC)). A method is provided for wireless communications. The method generally includes determining one or more blocks of data in a current packet matching one or more blocks of data in one or more portions of one or more previous packets stored in a memory, compressing at least a portion of the current packet based on an enhanced compression format having reduced metadata relative to another compression format to indicate one or more of the matching blocks of data, and transmitting the compressed current packet. Numerous other aspects are provided.

Enhanced compression formats for data compression

A user equipment (UE) and source base station may use data compression techniques for data packets sent between them. During a handover, the source base station may provide data compression context to a target base station, thus enabling the target base station to continue the data compression following the handover without having to reestablish the data compression context. The source base station may determine data compression capabilities of the UE or the target base station, or both, and may communicate the determined data compression capabilities to the UE or target base station. The source base station may identify at least one gap in a sequence of packets received from the UE, and communicate the existence of the gap to the target base station, which may request retransmission of packets associated with the gap.
