SWITCHING DIVERSITY IN SCALABLE RADIO FREQUENCY COMMUNICATION SYSTEM

摘要

A system implementing switching diversity in a scalable radio frequency communication system includes a primary radio frequency integrated circuit (RFIC), a first secondary RFIC, and a second secondary RFIC. The first secondary RFIC is configured to receive a radio frequency (RF) signal from a device via antenna elements based on a first beam setting, and transmit the RF signal to the primary RFIC. The primary RFIC is configured to receive the RF signal; downconvert the RF signal to an intermediate frequency (IF) signal; transmit the IF signal to a baseband processor; receive, from the baseband processor, a control signal including a second beam setting; and transmit the control signal to the second secondary RFIC. The second secondary RFIC is configured to receive the control signal from the first primary RFIC, and receive the first RF signal from the device via second antenna elements based on the second beam setting.

1. A system comprising:
a first secondary radio frequency integrated circuit (RFIC) configured to receive a first radio frequency (RF) signal from a device via first antenna elements based at least in part on a first beam setting, and transmit the first RF signal to a first primary RFIC; the first primary RFIC configured to:
receive the first RF signal from the first secondary RFIC;downconvert the first RF signal to a first intermediate frequency (IF) signal and transmit the first IF signal to a baseband processor;receive, from the baseband processor, a first control signal comprising a second beam setting for receiving the first RF signal through a second secondary RFIC; andtransmit the first control signal to the second secondary RFIC; and the second secondary RFIC configured to receive the first control signal from the first primary RFIC, and receive the first RF signal from the device via second antenna elements based at least in part on the second beam setting.
