Method to support channel estimation and corresponding base station

摘要

A CDMA mobile radio communication system down link channel estimation procedure with multiple antenna beam forming uses a pilot sequence transmitted from the base station (BS) on a shared channel with varying (VP) transmit power, beam forming vector and spreading code transmission parameters and processed by the mobile (MS) to estimate the channel properties. A CDMA mobile radio communication system down link channel estimation procedure with multiple antenna beam forming uses a pilot sequence transmitted from the base station (BS) on a shared channel with varying (VP) transmit power, beam forming vector and spreading code transmission parameters and processed by the mobile (MS) to estimate the channel properties. Includes an INDEPENDENT CLAIM for a base station using the system.
