Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Systems, methods, and devices of the various embodiments enable rate shaping of content data delivered to a client application. 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.

Abstract: 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.

Abstract: In overview, the various embodiments provide methods implemented by a processor executing a DASH client on a receiver device for determining when, in view of a change in the receiver device's resources (e.g., bandwidth, battery power, etc.), to cancel or abandon downloading the current segment at the current representation and restart download of the current segment at a different representation to meet one or more performance objectives and/or optimizations related to the change in the receiver device's resources. In various embodiments, the receiver device processor may perform a cost-benefit analysis to determine whether switching representations during the ongoing download of the current segment will benefit the performance of the receiver device, and the receiver device processor may switch representations in response to determining that switching representations would improve the performance of the receiver device.
