METHOD OF DETERMINING ORTHOGONAL RESOURCE BASED ON VIRTUAL CELL ID IN COMP COMMUNICATION SYSTEM

摘要

SUMMARY OF THE INVENTION The present invention provides a solution for providing a user equipment with a virtual cell ID at a receiving point in a communication system wherein a virtual cell ID corresponding to the first receiving point is received from the network controlling device, Used to indicate the cluster to which it belongs; The virtual cell ID is then provided to at least one user equipment served by the receiving point; Finally, resource index information corresponding to each user equipment of at least one user equipment is transmitted to each user equipment. In the user equipment of the communication system, a solution for determining orthogonal resources is additionally provided, wherein first a virtual cell ID of the receiving point is obtained; Then resource index information corresponding to the current user equipment is received from the receiving point; Next, an orthogonal resource corresponding to the current user equipment is determined according to the virtual cell ID and resource index information; And finally the uplink control information is transmitted to the receiving point through the determined orthogonal resource. A trade-off between the number of orthogonal resources and the interference strength can be achieved by the application of the present invention.
