摘要： An apparatus for adaptively defining clusters transmit points for coordination in a communication network includes a circuit that receives radio frequency channel information corresponding to the transmit points and defines a subset of the transmit points based at least in part on the radio frequency communication channel information. The subset is interrelated by a contiguous chain of dominant interference relationships between pairs of the transmit points. The apparatus further includes a processor that independently coordinates radio communications among the subset of transmit points.

摘要： Real-time video can be efficiently and reliably streamed over wireless networks by fountain encoding a stream of video packets at the frame-level. Specifically, deep packet inspection may be performed on the stream of video packets to identify a set of video packets corresponding to an intra-coded frame (I-frame). The set of video packet may then be fountain encoded together as a data segment to produce a set of fountain encoded packets corresponding to the I-frame. Video packets corresponding to other frames (e.g., P-frames, etc.) may also be encoded on a frame-by-frame basis. This may allow a user equipment (UE) to begin displaying earlier frames in a group of pictures (GoP) while fountain encoded packets for subsequent frames are still being received, thereby reducing latency and improving the overall user experience.
摘要翻译：通过在帧级编码视频数据包流，可以通过无线网络高效可靠地流式传输视频。具体地，可以对视频分组流执行深度分组检查，以识别与帧内编码帧（I帧）对应的一组视频分组。然后，该组视频分组可以一起作为数据段进行喷泉编码，以产生与I帧对应的一组喷泉编码分组。对应于其他帧（例如，P帧等）的视频分组也可以逐帧编码。这可以允许用户设备（UE）开始在一组图像（GoP）中显示较早的帧，而用于后续帧的喷泉编码分组仍然被接收，从而减少等待时间并改善整体用户体验。

摘要： Network caching performance can be improved by allowing users to discover distributed cache locations storing content of a central content server. Specifically, retrieving the content from a distributed cache proximately located to the user, rather than from the central content server, may allow for faster content delivery, while also consuming fewer network resources. Content can be associated with distributed cache locations storing that content by cache location tables, which may be maintained at intermediate network nodes, such as border routers and other devices positioned in-between end-users and central content servers. Upon receiving a query, the intermediate network nodes may determine whether the content requested by the query is associated with a cache location in the cache location table, and if so, provide the user with a query response identifying the associated cache location.
摘要翻译：通过允许用户发现存储中央内容服务器内容的分布式高速缓存位置，可以提高网络缓存性能。具体来说，从分布式高速缓存检索内容，而不是从中央内容服务器，而不是来自中央内容服务器，可以允许更快的内容传送，同时也消耗更少的网络资源。内容可以与通过高速缓存位置表存储该内容的分布式高速缓存位置相关联，高速缓存位置表可以在诸如边界路由器和位于最终用户与中央内容服务器之间的其他设备的中间网络节点处维护。在接收到查询之后，中间网络节点可以确定查询所请求的内容是否与高速缓存位置表中的高速缓存位置相关联，如果是，则向用户提供标识相关联的高速缓存位置的查询响应。

摘要： Disclosed is system and method to implement an on-demand file repair protocol. In the protocol, a traffic source sends all data packets of a data file to a traffic sink. The traffic source then sends to the traffic sink an indication that the sending of the all data packets is complete. If data packets are missing, a request is received from the traffic sink for retransmission of missing packets. The traffic source then sends fountain codes of the missing packets to the traffic sink.
