Abstract  Abstract

A mobile station when receiving a transmission diversity signal of executing handoff from the transmitting signal of the first base station to transmit diversity operation mode when the emission signal of the second base station in the transmission mode of operation of the method. In the method the mobile station communicating with a first base station in the transmission diversity mode of operation. before executing the handoff the mobile station communicating with the first base station in the non-transmission diversity mode of operation. in the process of handoff the mobile station communicating with the first and second base stations in non-transmission diversity mode of operation. after completing the handoff the mobile station communicates with a second base station in a non-transmission diversity mode of operation. after a predetermined time the mobile station using a transmit diversity operation mode and the second base station. It also provides other method for implementing switching wherein for example a mobile station and a base station using transmission diversity and non-transmission diversity mode of operation.

A method for performing a handoff when a mobile station receiving a transmission diversity signal travels from a first base station transmitting a signal in a transmission diversity mode of operation to a second base station transmitting a signal in the transmission diversity mode of operation. In the method the mobile station communicates with the first base station in the transmission diversity mode of operation. Prior to performing handoff the mobile station communicates with the first base station in a non-transmission diversity mode of operation. During the handhoff the mobile station communicates with the first and second base stations in the non-transmission diversity mode of operation. Upon completing the handhoff the mobile station communicates with the second base station in the non-transmission diversity mode of operation. After a predetermined time the mobile station communicates with the second base station in the transmission diversity mode of operation. Other methods for performing the handhoff are also provided where for example the mobile station and the base stations operate in the transmission diversity and the non-transmission diversity modes of operation.
