Abstract: There is provided a method for performing direct mobile-to-mobile communication in a cellular mobile communication system, the cellular mobile communication system having at least two mobile stations and a communication network. The method includes associating a first mobile station and a second mobile station with at least one base station of the communication network, performing neighbor discovery between the first mobile station and the second mobile station for reporting to the at least one base station, detecting the feasibility of direct communication between the first mobile station and the second mobile station, establishing a direct communication link between the at least two mobile stations, allocating identification for communication and flow and resources for a flow between the first mobile station and the second mobile station, synchronizing the flow between the first mobile station and the second mobile station, and sending automatic repeat requests (ARQ) messages.

Abstract: The present invention is directed to a base station including a transceiver configured to communicate with another base station using a radio resource, wherein the radio resource is allocated to the base station to serve communication devices located in a radio cell operated by the base station. A method of operating a base station is also disclosed.

Abstract: A method for enabling a forwarding to network operation in a cellular mobile communication system is described, the cellular mobile communication system comprising a plurality of mobile stations and at least one base station, the method comprising: reporting forwarding capability of a first mobile station of the plurality of mobile stations with the at least one base station; discovering neighboring mobile stations to the first mobile station; selecting a second mobile station from the neighboring mobile stations and establishing a forwarding link between the first mobile station and the second mobile station; allocating radio resources for a link between the first mobile station and the second mobile station; and synchronizing the link between the first mobile station and the second mobile station to establish the forwarding network.

Abstract: A infrastructure station in a cellular mobile communication system, the infrastructure station includes a infrastructure station core configured to provide infrastructure station functionality to a plurality of dependent stations, a topographer configured to discover a network topology and designate a failover topology from the network topology for use in the event that the infrastructure station fails thereby no longer being capable of providing infrastructure station functionality to the plurality of dependent stations, the failover topology comprising failover stations, and a synchronizer configured to periodically provide timing estimates of dependent stations to the failover stations such that network reentry after infrastructure station failure is shorter than normal network entry.

Abstract: The present invention is directed to a communication terminal in a wireless communication network. The communication terminal includes a receiver configured to receive a first message comprising a media access control (MAC) frame at a first transmission rate from a communication device in the wireless communication network; a message generator configured to generate a second message in response to the received first message, the second message comprising a control response frame; and a transmitter configured to transmit the control response frame at a second transmission rate, wherein the second transmission rate is lower than or equal to the first transmission rate; and wherein the second transmission rate is dependent on a difference in qualities between downlink communication and uplink communication between the communication device and the communication terminal. Methods of modulating a message for transmission in the wireless communication network are also disclosed.
