Methods and apparatus for adapting SRS switching accounting for measurement procedure

A method, in a network node, comprising:

• transmitting a configuration for reference signal carrier-based switching to a user equipment, the configuration comprising an indication of when to switch to one or more carriers;
• determining that the user equipment is to perform one or more radio measurements using a first set of reference time resources on at least a first cell operating on a first carrier frequency;
• determining, based on the indication of when to switch to one more carriers in the configuration for reference signal carrier-based switching and the first set of reference time resources, that performing reference signal carrier-based switching according to the obtained configuration will interfere with performing the one or more radio measurements;
• determining that the user equipment is to adaptively perform reference signal carrier based switching for transmitting a reference signal on a second cell operating on a second carrier frequency based on the determined first set of reference time resources so as to ensure that the first set of reference time resources is available for radio measurement;
• receiving the one or more measurements from the user equipment;
• and
• using a result of the adaptive reference signal carrier based switching for one or more operational tasks.

A user equipment comprising one or more processors, wherein the one or more processors are configured to:

• obtain a configuration for reference signal carrier-based switching, the configuration comprising an indication of when to switch to one or more carriers;
• determine that the user equipment is to perform one or more radio measurements using a first set of reference time resources on at least a first cell operating on a first carrier frequency;
• determine, based on the indication of when to switch to one more carriers in the configuration for reference signal carrier-based switching and the first set of reference time resources, that performing reference signal carrier-based switching according to the obtained configuration will interfere with performing the one or more radio measurements;
• adaptively perform reference signal carrier-based switching for transmitting a reference signal on a second cell operating on a second carrier frequency based on the determined first set of reference time resources, so as to ensure that the first set of reference time resources is available for radio measurement;
• and
• perform the one or more measurements using the first set of time resources.
