Abstract

This disclosure relates to techniques for performing inter radio access technology measurements without a measurement gap in a wireless communication system. A wireless device and a cellular base station may establish a wireless link according to a first radio access technology. The cellular base station may indicate to the wireless device to perform inter radio access technology measurements. The wireless device may determine that it is capable of performing the inter radio access technology measurements without a measurement gap. The wireless device may provide capability information to the cellular base station indicating that the wireless device is capable of performing the inter radio access technology measurements without a measurement gap. The wireless device may perform the inter radio access technology measurements without a measurement gap.

Claims20

Dependent claims

A method, comprising:

by a wireless device:
establishing a wireless link with a cellular base station according to a first radio access technology (RAT);
receiving an indication from the cellular base station to perform at least a first inter-RAT measurement;
determining that the wireless device is capable of performing the first inter-RAT measurement without a measurement gap;
determining that one or more of data or control communication on the wireless link with the cellular base station and the first inter-RAT measurement are associated with different subcarrier spacing;
determining that the wireless device does not support mixed numerology;
interrupting one or more of data or control communication on the wireless link with the cellular base station while performing the first inter-RAT measurement without a measurement gap based at least in part on one or more of data or control communication on the wireless link with the cellular base station and the first inter-RAT measurement being associated with different subcarrier spacing and the wireless device not supporting mixed numerology;
and
performing the first inter-RAT measurement without a measurement gap.
