The P2P LSP can be built from a core mLDP enabled LSR to the ingress edge LSR, across a non-mLDP enabled LSR between the core mLDP enabled LSR and the ingress edge LSR.

The base station sets the number of spatial multiplexing sequences (rank) of data being used by the mobile station when transmitting a PUSCH, further sets orthogonal resources used by the mobile station for the same number of reference signals as the set number of spatial multiplexing sequences which are transmitted together with the PUSCH, and transmits downlink control information indicating the number of spatial multiplexing sequences and information indicating the orthogonal resources for the reference signals. The mobile station receives the downlink control information, selects orthogonal resources to respectively apply to the reference signals, applies the selected orthogonal resources to generate the reference signals, and transmits the generated reference signals to the base station apparatus.

Abstract: Systems and methods for cellular or WIFI mobile traffic optimization based on public or private network destination are disclosed. One embodiment includes a mobile device whose traffic is optimized based on destination IP network type where the mobile device includes a local proxy which detects outgoing traffic and determines whether the outgoing traffic is directed towards a public IP network or private IP network. In general, the outgoing traffic is categorized as optimizable for mobile device battery conservation and/or network resource conservation if the outgoing traffic is directed towards the public IP network. Optimization of the outgoing traffic can be performed by a native operating system of the mobile device or an application that is non-native to the native operating system of the mobile device. The optimization can also be in part or in whole performed by a remote proxy in communication with the local proxy on the mobile device.
