METHOD AND APPARATUS FOR POWER CONTROL IN A MULTIPLE ANTENNA SYSTEM

摘要

The method involves multiplying selected antenna weights to produce a weighted transmission signal. The weighted signal is transmitted using an initial overall transmission power. The antenna weights in the transmission signal are adjusted. The transmission signal is retransmitted until a satisfactory signal strength acknowledgement is received from an intended receiver. The overall transmission power level of the transmission signal is increased when the acknowledgement is not received within a preset number of antenna weight adjustments. Independent claims are also included for the following: (1) a multi-antenna transmitter comprising a signal generator (2) an integrated circuit comprising a signal generator.
