RADIO COMMUNICATION SYSTEM, RADIO BASE STATION APPARATUS, USER TERMINAL AND RADIO COMMUNICATION METHOD

摘要

In order to enable user equipment (UE) to determine which cell a downlink signal comes from, thereby enabling reception accuracy to be maintained, even in a heterogeneous environment in which the same cell identification information is used, this wireless communication method is characterized in that: a wireless base station generates a reference signal sequence by using a pseudo-random sequence that includes user-specific information, and transmits the reference signal sequence to UE; and the UE uses the reference signal sequence transmitted by the wireless base station to perform signal processing.
