APPARATUS, METHOD AND COMPUTER PROGRAM PRODUCT PROVIDING COMMON PILOT CHANNEL FOR SOFT FREQUENCY REUSE

摘要

A method for operating a wireless communication system in a cell includes allocating a first plurality of pilot resources to a first frequency sub-band comprising a plurality of high power sub-carriers, allocating a second plurality of pilot resources to a second frequency sub-band comprising a plurality of low power sub-carriers, signaling a power offset between the plurality of pilot resources in the plurality of high power sub-carriers and the plurality of pilot resources in the plurality of low power sub-carriers, and transmitting the first and the second plurality of pilot resources over the first and the second frequency sub-bands.
