Title:
アップリンクパイロット及び分散されたユーザ近接検出に基づく基地局選択のメカニズム及び手順
Document Type and Number:
Japanese Patent JP6845871
Kind Code:
B2
Abstract:
A method and apparatus is disclosed herein for base station selection based on uplink pilot and distributed user-proximity detection. In one embodiment, the method comprises performing uplink pilot configuration for a plurality of user terminals over a set of common resource elements, including generating a plurality of pilot patterns for the plurality of user terminals, where each of the plurality of pilot patterns comprises at least one zero-power resource element and at least one non-zero-power resource element and at least one zero-power resource element allocated to each different one of the plurality of user terminals has a different position in the pilot pattern.
