A priority-resource-limited CoMP scheme is proposed based on a coordination priority index of users which comes into play to perform cooperation set selection and resource allocation in small cell networks. The CoMP control unit (CCU) configures and then transmits to the donor (serving) Transmission / Reception Point (TRP) the coordination priority index which is determined as a function of the required Bit Rate for that specific User Equipment and the SINR or the CQI.

The configuration of the coordination priority index allows the User Equipment to select a subset of Channel State Information reports or Channel State Information quantities to report so that the threshold index of the coordination priority is met.

The components retain the infrared blocking characteristic while allowing signal penetration, and remain substantially transparent in the visible spectrum, and any feature is difficult to detect by naked eyes. This performance is achieved by isolating the stack with conductive performance into discrete small cells by a gap pattern, the subsequent result being that the gap is covered by a secondary stack. The line width of the secondary stack is at least 0.4 microns larger than the gap between the small cell main stacks. The main stack increases from zero to full thickness near the gap with a sidewall transition length exceeding 0.2 microns.
