Method for determining orthogonal resource based on virtual cell ID in CoMP communication system

摘要

The invention provides a solution, in a reception point of a communication system, of providing a user equipment with a virtual cell ID, where firstly a virtual cell ID corresponding to the reception point is received from a network control device, the virtual cell ID being used for indicating a cluster to which the reception point belongs; then the virtual cell ID is provided to at least one user equipment served by the reception point; and finally resource index information corresponding to each user equipment among the at least one user equipment is transmitted respectively to the each user equipment. There is further provided a solution, in a user equipment of a communication system, of determining an orthogonal resource, where firstly a virtual cell ID of the reception point is obtained; then resource index information corresponding to the present user equipment is received from the reception point; next an orthogonal resource corresponding to the present user equipment is determined according to the virtual cell ID and the resource index information; and finally uplink control information is transmitted to the reception point over the determined orthogonal resource. A tradeoff between the number of orthogonal resources and interference intensity can be achieved by applying of the invention.
