Frequency division duplexing in paired uplink and downlink bands

A method for wireless communications by a user equipment (UE), comprising:

• receiving a first downlink reference signal in a first frequency band to determine one or more first channel conditions associated with the first frequency band, the first downlink reference signal associated with downlink communications;
• receiving a second downlink reference signal in a second frequency band to determine one or more second channel conditions associated with the second frequency band, the second downlink reference signal associated with uplink communications;
• and
• transmitting one or more uplink signals in the second frequency band in accordance with one or more transmission parameters that are based at least in part on the one or more second channel conditions determined using the second downlink reference signal.

A non-transitory computer-readable medium storing code for wireless communications, the code comprising instructions executable by one or more processors to:

• receive a first downlink reference signal in a first frequency band to determine one or more first channel conditions associated with the first frequency band, the first downlink reference signal associated with downlink communications;
• receive a second downlink reference signal in a second frequency band to determine one or more second channel conditions associated with the second frequency band, the second downlink reference signal associated with uplink communications;
• and
• transmit one or more uplink signals in the second frequency band in accordance with one or more transmission parameters that are based at least in part on the one or more second channel conditions determined using the second downlink reference signal.
