TECHNIQUES FOR CHANNEL MEASUREMENTS FOR MULTIPLE UPLINK CARRIERS IN CARRIER AGGREGATION

Abstract

Methods, systems, and devices for wireless communications are described for channel measurements for multiple uplink carriers in carrier aggregation (CA). A CA configuration may provide a first downlink carrier, a first uplink carrier, and a second uplink carrier. The second uplink carrier may be a supplemental uplink (SUL) carrier that does not have an associated downlink carrier in a same frequency band. A measurement downlink carrier may be configured and associated with the second uplink carrier, and measurements of a reference resource of the measurement downlink carrier may be used to determine transmission parameters of the second uplink carrier.
