Method of determining orthogonal resource based on virtual cell id in comp communication system

A method, in a reception point of a communication system, of providing a user equipment with a virtual cell ID, the method comprising:

• receiving a virtual cell ID corresponding to the reception point from a network control device, the virtual cell ID being used for indicating a cluster to which the reception point belongs;
• providing the virtual cell ID to at least one user equipment served by the reception point;
• and
• transmitting resource index information corresponding to each user equipment among the at least one user equipment respectively to the each user equipment.

A method, in a user equipment of a communication system, of determining an orthogonal resource, the user equipment being served by a reception point, and the method comprising:

• obtaining a virtual cell ID of the reception point;
• receiving resource index information corresponding to the present user equipment from the reception point;
• determining an orthogonal resource corresponding to the present user equipment according to the virtual cell ID and the resource index information;
• and
• transmitting uplink control information to the reception point over the determined orthogonal resource.

An apparatus, in a reception point of a communication system, for providing a user equipment with a virtual cell ID, the apparatus comprising:

• a first receiving device configured to receive a virtual cell ID corresponding to the reception point from a network control device, the virtual cell ID being used for indicating a cluster to which the reception point belongs;
• a providing device configured to provide the virtual cell ID to at least one user equipment served by the reception point;
• and
• a second transmitting device configured to transmit resource index information corresponding to each user equipment among the at least one user equipment respectively to the each user equipment.
