Base station selection mechanism and procedure based on uplink pilot and distributed user proximity detection

摘要

Disclosed herein are methods and apparatus for base station selection based on uplink pilots and distributed user proximity detection. In one embodiment, the method comprises performing uplink pilot configuration of multiple user terminals for a set of common resource elements, comprising generating multiple pilot patterns of the multiple user terminals Each of the plurality of pilot patterns includes at least one zero power resource element and at least one non-zero power resource element, and at least one zero power resource element assigned to each different one of the plurality of user terminals is And including steps having different positions within the pilot pattern.
