摘要： Embodiments are provided for implementing traffic engineering (TE) using link buffer status. The link buffer status for each link is used to identify links with buffer build-ups. One or more of the capacity and resource parameters at the links with buffer build-ups are then reserved. This is achieved by modifying the capacity and resource input parameters to the TE model according to the level of build-ups in the link buffers, as reflected by the buffer status information from the links and nodes. The modified input capacity or resource parameters are then fed to a TE engine to calculate the routing of traffic across all links and paths. As such, the reserved capacity or resource is considered in the TE routing technique to route the traffic accordingly, leading to the depletion of link buffers with build-ups at all or multiple considered paths at the same time.

摘要： Method and apparatus for decoding a transmitted signal by a receiver in a MIMO system into a first estimate component for estimating a first signal, a first interference component indicating interference resulting from a correlation relationship among a set of signals to be transmitted, and a first noise component. A base station generates the transmitted signal from the set of signals through a coding process, the coding process defining a correlation relationship amongst the set of signals. The correlation information about the correlation relationship is transmitted to the receiver directly or by a dedicated reference symbol. The decoding is performed by determining a linear receiver filter for the first signal in accordance with the correlation information, and de-correlating the first signal and interferences.
