Patent ID: 8155023

Claim:
A process of spatial multiplexing in a wireless cellular communications network having a primary base station in a first cell, a secondary base station in a second cell adjacent the first cell, a low-latency, high throughput link between the primary base station and the secondary base station, and one user equipment in an edge region between the first cell and second cells, comprising: A. sending from the primary base station to the secondary base station over the link packets containing media access control layer transport block information for the one user equipment; B. establishing from the media access control layer transport block information identical reserved resource block spaces in the resource blocks in the primary and secondary base stations and a reservation schedule in the secondary base station for the one user equipment; C. reserving resource block spaces in the resource blocks in the secondary base station for more than one user equipment including reserving transmission to the one user equipment in one subcarrier frequency at one time and reserving transmission to another user equipment in another subcarrier frequency at the same time; D. transmitting from the primary base station to the user equipment PHY control channel information for the one user equipment; E. simultaneously transmitting from the primary and secondary base stations the media access control layer transport block information to the one user equipment; F. receiving from the one user equipment in the primary and secondary base stations one of an acknowledgement and no acknowledgement; and G. releasing the reserved resource block spaces in the secondary base station after a certain time if the secondary base station has not received scheduling information from the primary base station.
