Abstract
A communication system for a vehicle includes a transceiver and a telematics control module. The transceiver receives data from a network device using first antennas disposed external to a vehicle and second antennas disposed internal to the vehicle. The transceiver receives the data using a first antenna combination including two antennas, which include one or more of the first antennas or one or more of the second antennas. The telematics control module: reads channel state information including reference signal received power (RSRP) and rank indicator (RI) values; determines if the RSRP value is greater than a threshold value and the RI value is less than a minimum number of antennas being used to transfer the data; and based on the first RSRP value being greater than the threshold value and the RI value being less than the number of antennas, switches from the first to a second antenna combination.
