Abstract: A method of downloading video contents from a content server to a client through a base station of a wireless communication network is provided. Each video content includes a sequence of encoded video frames. The method includes having the content server send a video content in a sequence of data packets, each data packet including data corresponding to at least one portion of an encoded video frame, and having a proxy server at the base station classify each data packet according to the type of video frame it correspond to. The method also includes having a scheduler at the base station assign radio resources for the transmission of the data packets to the client based on the classification carried out by the proxy server, and transmitting the data packets to the client by exploiting the radio resource assignment carried out by the scheduler.

Abstract: A method of downloading a multimedia content from a content server to a client through a wireless communication network is provided. The multimedia content is subdivided into a plurality of chunks and for each chunk the content server has at least two corresponding versions thereof encoded with different encoding rates. The method includes having the client send a first request of a first version of a corresponding requested chunk, and having a proxy server intercept the first request to generate a second request of a second version of the requested chunk. The method also includes having the proxy server send the second request to the content server in place of the first request, and having the content server send the second version to the client. The second request is generated based on the amount of information content of the versions of said requested chunk.

Abstract: A method for estimating a signal to interference and noise ratio of a communication link between a fist node and a second node of a wireless communication network, the network comprising a number of further communication links between said first node and a number of further nodes. The method comprises, at the first node, providing first estimates of useful signal powers on all the links; providing second estimates of the signal powers on the link and on the further communication links on the basis of, jointly, the first estimate of the signal power on the link and the first estimates of the signal powers on the further links; estimating the signal to interference and noise ratio as a ratio between the second estimate of the signal power on the link and a power term comprising a sum of the second estimates of the signal powers on the further links.

Abstract: A method for scheduling radio resource allocation among active flows within a wireless communication network. The method includes, at each working period of the scheduling method; for each active flow, checking presence of priority data to be transmitted within the current working period. Each active flow having priority data to be transmitted within the current working period is classified as a priority active flow. The remaining active flows are classified as non-priority active flows, the non-priority active flows having non-priority data that need not to be transmitted within the current working period. Radio resources are allocated among the priority active flows, and corresponding priority data are transmitted over the respective allocated resources. After completing priority data transmission, the radio resources are allocated among the non-priority active flows and corresponding non-priority data are transmitted over the respective allocated radio resources until the end of the current working period.

Abstract translation: 一种在无线通信网络内的主动流中调度无线资源分配的方法。 该方法包括在调度方法的每个工作周期; 对于每个活动流程，检查在当前工作时段内要发送的优先级数据的存在。 在当前工作时段内要发送的具有优先权数据的每个活动流被分类为优先活动流。 剩余的活动流被分类为非优先级活动流，非优先级活动流具有在当前工作周期内不需要传送的非优先级数据。 在优先活动流中分配无线资源，通过各自分配的资源发送对应的优先级数据。 完成优先级数据传输后，在非优先级活动流中分配无线资源，相应的非优先级数据通过各自分配的无线电资源发送，直至当前工作周期结束。
