Cloud radio access network
Abstract:
Instead of just consuming network resources, client devices create network resources via cooperative subspace processing to increase data bandwidth and expand radio coverage so the network grows dynamically with demand. Server-side cooperative-MIMO provides joint processing for geographically distributed base stations with overlapping coverage areas. A combination of centralized coordination and distributed computing pools and virtualizes base station processing, which reduces complexity, size, and power requirements of base stations to facilitate rapid and inexpensive network deployments. Cooperative subspace coding reduces overhead and transport-layer inefficiencies, and enables each channel to simultaneously employ multiple network paths, even over non-homogeneous networks. Cooperative subspace processing enables a client in a first network to reuse its allocated channels for communicating in another network without interfering with the first network.
