3GPP45.005GSM/EDGE Radio transmission and receptionTS

The received signal level in table 1v refers to the signal level of VAMOS subchannel 2. In addition to the GMSK signal from VAMOS subchannel 2 at signal level according to table 1v, the signal from VAMOS subchannel 1 is also added at both the RX antennas. The ratio of the received power of VAMOS subchannel 2 relative to the received power of VAMOS subchannel 1 shall be equal to the Subchannel power imbalance ratio on uplink (SCPIR_UL) as specified in table 1v.
