Channel state information (CSI) measurement and report for dynamic spectrum sharing (DSS) in a wireless wide area network (WWAN)

A method for dynamic spectrum sharing (DSS) in a wireless wide area network (WWAN) performed by a first node, comprising:

• transmitting, to a second node, a control message that indicates one of a first subframe of a frame or a second subframe of the frame in which one or more channel state information (CSI) reference signals (CSI-RSs) are to be provided to the second node, wherein the first subframe is associated with a first subframe type and the second subframe is associated with a second subframe type;
• receiving a first signal quality report from the second node, the first signal quality report indicating a third signal quality measurement that is a combination of a first signal quality measurement weighted by a percentage of the frame that includes subframes of the first subframe type and a second signal quality measurement weighted by a percentage of the frame that includes subframes of the second subframe type;
• and
• scheduling a data transmission in at least one of the first subframe and the second subframe, the scheduling being associated with the third signal quality measurement.

An apparatus of a first node configured to implement dynamic spectrum sharing (DSS) in a wireless wide area network (WWAN), the apparatus comprising:

• one or more processors;
• one or more memories coupled with the one or more processors;
• and
• one or more processor-readable instructions stored in the one or more memories and executable by the one or more processors individually or collectively to cause the apparatus to:
• perform a first signal quality measurement associated with a first subframe of a frame received from a second node, and perform a second signal quality measurement associated with a second subframe of the frame, wherein the first subframe is associated with a first subframe type and the second subframe is associated with a second subframe type;
• identify that a first percentage of the frame includes subframes of the first subframe type, wherein the first signal quality measurement is associated with the subframes of the first subframe type;
• identify that a second percentage of the frame includes subframes of the second subframe type, wherein the second signal quality measurement is associated with the subframes of the second subframe type;
• weigh the first signal quality measurement according to the first percentage and the second signal quality measurement according to the second percentage;
• calculate a third signal quality measurement using the weighted first signal quality measurement and the weighted second signal quality measurement;
• and
• transmit, to the second node, a first signal quality report associated with at least one of the first signal quality measurement and the second signal quality measurement, and including the third signal quality measurement that is calculated using the weighted first signal quality measurement and the weighted second signal quality measurement.
