Abstract
This invention discloses a method in a wireless communication network, the method comprises generating a first piece of feedback information by a first hub serving a user terminal, transmitting a second piece of feedback information to the first hub by a second hub, combining the first and second pieces of feedback information by the first hub to form a third piece of feedback information, and transmitting the third piece of feedback information to the user terminal.
Claims13
A method in a wireless communication network having multiple hubs and a user terminal, the method comprising:
- designating one of multiple non-serving hubs or a serving hub as a center hub, wherein each hub within the reception range of the user terminal generates a first feedback information including reception quality information, wherein the center hub is a dedicated hub exclusively for feeding feedback information to the user terminal;
- transmitting the first feedback information corresponding to the user terminal to the center hub by all non-serving hubs within the reception range of the user terminal;
- combining all the first feedback information to a first combined feedback information by the center hub;
- transmitting the first combined feedback information to the serving hub by the center hub;
- combining the first combined feedback information with a second feedback information generated by the serving hub to form a second combined feedback information;
- and
- transmitting the second combined feedback information to the user terminal by the serving hub, wherein the first feedback information from the non-serving hubs is transmitted only to the center hub to reduce reception and processing elements at the multiple hubs and the user terminal.
A wireless communication network having multiple hubs, the network comprising:
- a serving hub;
- a center hub designated by the network, the center hub being one of multiple non-serving hubs or the serving hub, wherein the center hub receives a first feedback information corresponding to a user terminal generated by non-serving hubs within the reception range of the user terminal and combines all the first feedback information to a first combined feedback information, the center hub being a dedicated hub exclusively for feeding feedback information to the user terminal,
- wherein the center hub transmits the first combined feedback information to the serving hub, the serving hub combines a second feedback information generated by the serving hub with the first combined feedback information to form a second combined feedback information, and
- wherein the serving hub transmits the second combined feedback information to the user terminal which receives no feedback information from the non-serving hubs such that the number of data streams sent to the user terminal is reduced, and
- wherein the first feedback information from the non-serving hubs is transmitted only to the center hub to reduce reception and processing elements at the multiple hubs.
A method for reducing data stream received by a user terminal in a wireless communication network having multiple hubs, the method comprising:
- designating one of a plurality of non-serving hubs within the reception range of the user terminal as a center hub, wherein each of the plurality of non-serving hubs generates feedback information corresponding to the user terminal and transmits the feedback information to the center hub, and the center hub is a dedicated huh exclusively for feeding, feedback information to the user terminal;
- combining all the feedback information to form a first combined feedback information by the center hub;
- transmitting the first combined feedback information to a serving hub by the center hub;
- combining the first combined feedback information with a feedback information generated by the serving hub to form a second combined feedback information;
- and
- transmitting the second combined feedback information to the user terminal by the serving hub, wherein the user terminal receives no feedback information from the non-serving hubs such that the number of data streams sent to the user terminal is reduced,
- wherein the feedback information from the non-serving hubs is transmitted only to the center hub to reduce reception and processing elements at the multiple hubs.
