摘要： Various methods and devices are provided to address the need for improved cooperation-based signal processing. In a first method, network equipment determines (801) a set of dominant interferers for a wireless transmission and requests (802) user-plane data corresponding to each dominant interferer in the set of dominant interferers. The network equipment then processes (803) a received signal corresponding to the wireless transmission to extract the information transmitted. This processing uses at least some user-plane data corresponding to at least one dominant interferer in the set of dominant interferers.

摘要： In a method for dynamically setting a content rate of a multimedia session for a client in a network, a proxy server receives a channel condition feedback message from a network controller and determines whether a receiver report message has been received from the client since a most recent previous channel condition feedback message. The channel condition feedback message includes current channel condition information for the network. The proxy server sends one of an extended feedback report message and a short feedback report message to a media server based on the determining step. The short feedback report message includes at least a maximum transmission rate parameter for the multimedia session. The extended feedback report message includes at least information contained in the receiver report message. The extended feedback report message may, in addition, include the maximum transmission rate parameter for the multimedia session.

摘要： In an application level multicast (ALM), multiple flows of data packets containing shared material are destined for different devices. A packet compression device is used to compress the data packets to reduce traffic load. This compression device includes a cache for recording the payloads of selected data packets which currently are not of record in the cache. If it is determined that the cache has therein a record of an identical version of the payload of a data packet, the compression device releases a compressed version of the data packet which includes a representation of the payload in lieu of the actual payload.

摘要： Methods for proxy-driven content rate selection for streaming media servers are provided. In one method, one or more maximum transmission rate parameters from a network controller are stored at a proxy server in response to a receiver report message from the client. A target rate for the media session is generated based on the stored maximum transmission rate parameters, and the target rate is transmitted to a media server in a proxy-to-server feedback message. The media server selects the content rate from among a plurality of supported content rates in response to the proxy-to-server feedback message from the proxy server, and streams streaming multimedia frames to the client at the selected content rate.
