If the UE receives an ACTIVE SET UPDATE, CELL UPDATE CONFIRM, or any reconfiguration message:

1> if the IE "MIMO mode with four transmit antennas parameters" is not included:

2> clear the MIMO_MODE_WITH_FOUR_TRANSMIT_ANTENNAS_PARAMS variable;

2> trigger lower layers to stop operation in MIMO mode with four transmit antennas.

1> otherwise:

2> if the IE "MIMO mode with four transmit antennas N_cqi_typeA/M_cqi ratio" is included:

3> store the value of the IE "MIMO mode with four transmit antennas N_cqi_typeA/M_cqi ratio" in the MIMO_MODE_WITH_FOUR_TRANSMIT_ANTENNAS_PARAMS variable.

2> if the IE "MIMO mode with four transmit antennas pilot configuration" is included:

3> store the value of the IE "MIMO mode with four transmit antennas pilot configuration" in the MIMO_MODE_WITH_FOUR_TRANSMIT_ANTENNAS_PARAMS variable.
