Wireless multi-hop system with macroscopic multiplexing
DCFirst Claim
1. A method for communicating in a wireless multi-hop system having at least one base station, at least one relay station, and user equipment, the method comprising:
- facilitating, at a first relay station, a communication between user equipment and the first relay station using a second radio interface; and
multiplexing the communication between the first relay station and a base station and between the first relay station and a second relay station using a first radio interface to create a plurality of simultaneous data streams; and
processing the communication between the first relay station and the base station with the first radio interface separately from the communication between the user equipment and the first relay station.

Abstract
A method, device, and system in which radio links between relays and users are optimized separately from the links between relays and base stations and in which multiple simultaneous data streams between relays and base stations are created. The system includes transceivers of at least three kinds with two kinds of radio interfaces. The first kind of transceiver, a base station (BS), is connected to the core network with a link of wire line quality. The second kind, a relay station (RS), is connected to the BS with a first radio interface, and to the third kind, the user equipment (UE), with a second radio interface. The first and second radio interfaces can operate, at least in part, using the same frequency bandwidth. The UE can also connect directly to the BS using the second radio interface if the BS is closer than any RS.

11. A wireless communication system having a base station and a relay station that communicate with user equipment, the system comprising:
-
a base station having a first radio transceiver and being connected to a core network; and a first relay station having a second radio transceiver and being configured to simultaneously communicate with the base station and with a second relay station using a first radio interface and being configured to communicate with user equipment having a third radio transceiver using a second radio interface, wherein the operation of the first radio interface and the second radio interface are separate from each other. - View Dependent Claims (12, 13)
