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: 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.

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: 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.

Abstract: A method is described for adapting the size of data for a future Transmission Time Interval (TTI) by a User Equipment (UE), wherein all the Media Access Control (MAC)-d flows are grouped and stored in different lists based on a type of grants associated with the MAC-d flows, ability of a MAC-d flow to be multiplexed with another MAC-d flow from a list, and data availability in a logical channel mapped onto a MAC-d flow in the current TTI. The E-TFC is then selected by the UE for the future TTI using the MAC-d flow having the highest power offset in a consolidated list including the grouped MAC-d flows. The size of the data is thereby adapted using the selected E-TFC. Further disclosed is a method for generating RLC PDUs by the UE for the future TTI using the variation in the scheduled grant for the UE and the size of the data adapted for the future TTI.

Abstract: A method and system for handling security synchronization for prolonged periods of no-reception of voice frames. The method includes receiving one or more protocol data units (PDUs) by a radio link control (RLC) sub layer and determining a time period between the receiving of each PDU and a previously received PDU by the RLC sub layer. Further, the method includes initiating recovery procedure for the time period exceeding a first predefined time. The recovery procedure includes identifying count of the one or more PDUs to be recovered, deciphering each PDU using a plurality of hyper frame numbers (HFNs) and updating a master HFN based on the deciphering. The master HFN deciphers each PDU among the one or more protocol data units. Further, the method also includes delivering the one or more PDUs to a packet data convergence protocol sub layer where type verification of the PDU is performed.

Abstract: Wireless devices operate under network control. The network sends access control information for receipt by wireless devices that are operating in a suspended connected mode or idle mode under control of the network. The access control information operates to control access to the network by the wireless devices regardless of whether the wireless devices are operating in a suspended connected mode or idle mode.

Abstract: A method and apparatus for performing measurements in a multi-carrier environment are provided. In the method, a request to perform measurements on a frequency corresponding to one of at least one frequency band is received from a base station. It is determined whether a compressed mode is to be applied on the frequency corresponding to the one of the at least one frequency band based on capabilities of a user equipment. If so, the compressed mode is applied on the frequency corresponding to the one of the at least one frequency band so that measurements can be performed on the frequency corresponding to the one of the at least one frequency band without interrupting data activity on the remaining frequency bands. Otherwise, measurements are performed on the frequency corresponding to the one of the at least one frequency band without applying the compressed mode.

Abstract: A serving cell change method and apparatus is provided for efficiently performing the serving cell change in a mobile communication system. The UE receives a cell change control information including an activation time from a serving cell, when a downlink channel status of the serving cell is inferior to a downlink channel status of a target cell, reports a measurement result to the serving cell while performing data communication with the serving cell, monitors receipt of a cell change indicator transmitted by the target cell before the expiration of the activation time while performing the data communication with the serving cell, and when the cell change indicator is received, communicates data with the target cell by sending an acknowledgement in response to the cell change indicator and switching to the target cell.

Abstract: A method and apparatus are provided for determining a Transmission Power Control (TPC) command of an UpLink (UL) channel in a User Equipment (UE). The method includes storing TPC commands received through each Radio Link (RL) for preset combining periods, before entry into Discontinuous Transmission (DTX); combining the stored TPC commands; if all of the TPC commands are UP commands, determining a combined TPC command of the UL channel as a power level derived using a TPC command received in a designated previous DownLink (DL) slot among DL slots included in each RL, and controlling a transmit power of the UL channel, in a current DL slot which uplink transmission is resumed, using a power level corresponding to the determined TPC command.
