摘要： Methods, systems, and devices for wireless communications are described. A wireless device may establish connectivity between the wireless device and a user equipment (UE) via a first communication path, and between the wireless device and the UE via a second communication path that includes a relay device. The wireless device may transmit, via the first communication path, a first message in a first format to the UE, including first data, and transmit, via the second communication path to the relay device, a second message in a second format and including the first data, the second format indicating that the relay device is to relay the first data to the UE. The relay device may receive, via a first portion of the second communication path, the first message and may transmit, to the UE via a second portion of the second path, a second message including the first data.

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： 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 and apparatuses are disclosed for a network controller to receive data from a user terminal (UT) via a satellite in a satellite system. The network controller may allocate contention-based resources of the satellite system to a plurality of UTs, and may activate the allocated contention-based resources by transmitting an activation signal to the plurality of UTs. The network controller may receive, from a first UT via a satellite of the satellite system, a first portion of data on a plurality of subframes of the contention-based resources during a time period, and may suspend the allocation of contention-based resources after an expiration of the time period or upon a grant of scheduled return link resources to the first UT, irrespective of collisions on the contention-based resources.

摘要： According to some aspects, a transport accelerator of a client device may generate a chunk request that is derived from a fragment request and that has transport acceleration metadata. The transport acceleration metadata may indicate that the request is from a transport accelerator and/or indicate a fragment associated with the fragment request. The transport accelerator may receive a signal to cancel one or more chunk requests and/or wait to receive a full fragment. A client application of the client device may generate the signal upon receipt of an HTTP response from a server that complies with a handshaking procedure.

摘要： A method and apparatus for operating a user terminal in a satellite communication system during inter-beam handovers. In some aspects, the user terminal may determine an occurrence of an inter-beam handover for switching communication with a network controller of the satellite communication system from a first beam to a second beam. The user terminal measures a channel quality of the second beam based at least in part on the occurrence of the inter-beam handover, and sends the channel quality measurement to the controller via a reverse-link communication.

摘要： Handover parameter settings are automatically adapted in access points in a system to improve handover performance. Reactive detection techniques are employed for identifying different types of handover-related failures and adapting handover parameters based on this detection. Messaging schemes are also employed for providing handover-related information to access points. Proactive detection techniques also may be used for identifying conditions that may lead to handover-related failures and then adapting handover parameters in an attempt to prevent such handover-related failures. Ping-ponging may be mitigated by adapting handover parameters based on analysis of access terminal visited cell history acquired by access points in the system. In addition, configurable parameters (e.g., timer values) may be used to detect handover-related failures.

摘要： Systems and methods which are adapted to provide selective transport accelerator operation are disclosed. In operation according to embodiments, one or more functions of transport accelerator operation is selectively bypassed or not based upon particular criteria. Transport accelerator control logic may obtain one or more acceleration selection attributes and, based on the one or more acceleration selection attributes, selectively invoke first functionality of transport accelerator logic of a client device to obtain the content from the content server or bypassing the first functionality of the transport accelerator logic of the client device to obtain the content from the content server. The first functionality may comprise subdividing the user agent's request for content into a plurality of chunk requests for requesting chunks of the content from the content server to provide accelerated delivery of the content to the client device.
