Abstract

The techniques described herein provide enhanced measurement gap sharing solutions that enable measurement gap sharing for layer 1 (L1) measurements for serving and non-serving cells, and for layer 3 (L3) measurements for intra-frequency measurements and inter-frequency/inter-radio access technology (RAT) measurements. Also provided are solutions for measurement gap sharing among intra-frequency L1 and L3 measurements and inter-frequency L1 and L3 measurements. Measurement gap patterns for L1 and L3 measurements are also provided, as well as solutions for further splitting L1 measurement gap sharing among different types of L1 operations.
