摘要： 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.

摘要： Methods, systems, and devices for wireless communications are described. In an example, a method includes a first node receiving a precision time protocol (PTP) message, identifying one or more timing domains to be supported by the first node based at least in part on the PTP message, and sending, to a second node of the wireless communication network, an indicator of the one or more timing domains to be supported by the first node. Another example at a node includes receiving, from additional nodes of the wireless communication network, indicators of one or more timing domains supported by the additional nodes, receiving a PTP message associated with a timing domain, and sending the PTP message to a subset of the additional nodes based at least in a part on the indicators of one or more timing domains supported by the additional nodes.

摘要： Methods, systems, and devices for wireless communications are described. In an example ingress point of a wireless communication network, a method includes receiving a first ethernet frame comprising a precision time protocol (PTP) message at a first node and determining an ingress time for the PTP message, generating a packet data unit (PDU) for transmission to a second node of the wireless communication network based at least in part on the first ethernet frame by overwriting a field in the PTP message with a value corresponding to the ingress time, and sending the PDU to the second node. An egress point method may include receiving a PDU comprising a PTP message, determining an ingress time from a field in the PTP message overwritten with a value corresponding to the ingress time, and determining an adjustment for a timing parameter based at least in part on the ingress time.

摘要： Local IP access is provided in a wireless network to facilitate access to one or more local services. In some implementations, different IP interfaces are used for accessing different services (e.g., local services and operator network services). A list that maps packet destinations to IP interfaces may be employed to determine which IP interface is to be used for sending a given packet. In some implementations an access point provides a proxy function (e.g., a proxy ARP function) for an access terminal. In some implementations an access point provides an agent function (e.g., a DHCP function) for an access terminal. NAT operations may be performed at an access point to enable the access terminal to access local services. In some aspects, an access point may determine whether to send a packet from an access terminal via a protocol tunnel based on the destination of the packet.

摘要： Various aspects of the disclosure relate to handoff of a user terminal in communication with a gateway through a satellite in a non-geosynchronous satellite communication system. In some aspects, a gateway and a user terminal use a satellite and beam transition table to determine when to handoff the user terminal from one beam to another and/or from one satellite to another. In some aspects, a user terminal sends capability information, location information, or other information to a gateway whereby, based on this information, the gateway generates a satellite and beam transition table and/or selects a handoff procedure for the user terminal. In some aspects, handoff of a user terminal to a different satellite involves the user terminal conducting satellite signal measurements and sending a measurement message to the gateway. In some aspects, the gateway generates a new satellite and beam transition table as a result of receiving a measurement message.

摘要： Methods and apparatuses are disclosed for a user terminal (UT) to transmit data to a network controller via a satellite in a satellite system. The UT may begin transmitting, during a time period, a first portion of the data using contention-based resources of the satellite system prior to receiving a grant of scheduled return link resources of the satellite system. The UT may also transmit, on the contention-based resources, a buffer status report (BSR) during the time period. The UT may terminate data transmissions on the contention-based resources after an expiration of the time period or upon receiving the grant of scheduled return link resources. After receiving the grant, the UT may transmit a second portion of the data on the scheduled return link resources.

摘要： A method and apparatus for operating a satellite access network (SAN) of a satellite communication system to schedule communications with a user terminal. In some aspects, the SAN may provision a communication frame, for the user terminal, into a number of forward-link (FL) subframes and a different number of reverse-link (RL) subframes. The SAN then transmits the FL subframes to the user terminal via a forward link of the satellite communication system, and subsequently receives the RL subframes from the user terminal via a reverse link of the satellite communication system.

摘要： Techniques are described for wireless communication. One method includes encapsulating and segmenting a packet data convergence protocol (PDCP) protocol data unit (PDU), at a medium access control (MAC) layer, to form at least a first MAC service data unit (SDU) and a second MAC SDU; mapping the first MAC SDU to a first MAC PDU and the second MAC SDU to a second MAC PDU; and transmitting the first MAC PDU in a first transport block and the second MAC PDU in a second transport block. In some method examples, the encapsulating may include segmenting the PDCP PDU. In some examples, the method may include transmitting framing information in the first transport block and the second transport block. In some examples, the framing information for a transport block may be transmitted in at least one MAC sub-header of the transport block.

A processor may determine an ingress rate of content data to a buffer. The processor may determine an amount of the content data stored in the buffer. The processor may determine an egress rate of the content data from the buffer to the client application based on the ingress rate and the amount of content data stored in the buffer. The processor may send the content data from the buffer to the client application at the egress rate.
