PROBLEM TO BE SOLVED: To provide systems and methods that designate a control attachment point(s) during transmission of data in a coordinated multipoint (CoMP) system.SOLUTION: The control attachment point is represented by an anchor cell to address control signaling and represent interaction of user equipment (UE) with a wireless communication system from a perspective of control (e.g., supplying/sending grants to the UE, transmitting/receiving ACKS on a downlink/uplink to the UE and control information (CQI), and the like.) The cells can further engage in backhaul transfer of information therebetween, and dynamic switching/change of an anchor point based on criteria such as control loading and channel quality can further be implemented. |
