Method and apparatus for shifting control areas in a wireless communication system
First Claim
1. An apparatus for assigning a plurality of access nodes of a wireless communication network to control areas, the apparatus comprising:
- a processing apparatus, configured to;
assign each access node in the plurality of access nodes to a control area of a plurality of control areas;
determine a first control phase, wherein a control phase comprises a period of time during which the assignment of access nodes to control areas remains constant;
when changing from the first control phase to a following second control phase;
reassign at least a subset of access nodes which were assigned to a first control area of the plurality of control areas during the first control phase to a second control area of the plurality of control areas, andreassign at least a subset of access nodes which were assigned to a third control area of the plurality of control areas during the first control phase to the first control area;
reassign the control areas such that an access node that is adjacent a boundary of the first control area during the first control phase is no longer adjacent the boundary of the first control area during the following second control phase; and
instruct access nodes assigned to a same control area to perform coordinated multi-point transmission or reception or multi-input multi-output type transmissions.

Abstract
An apparatus for assigning a plurality of access nodes of a wireless communication network to control areas includes a processing apparatus. The processing apparatus is configured to assign each access node in the plurality of access nodes to a control area of a plurality of control areas and to determine a first control phase. The first control phase is a period of time during which the assignment of access nodes to control areas remains constant. The processing apparatus is configured to, when changing from the first control phase to a following second control phase, reassign at least a subset of access nodes which were assigned during the first control phase to a first control area to a second control area and reassign at least a subset of access nodes which were assigned during the first control phase to a third control area to the first control area.
