Abstract

Claims (73)

1 . A method implemented in a wireless device, WD, which has been configured with concurrent measurement gap patterns, the method comprising:

determining that one or more measurement gap conflicts will arise such that two measurement gaps in the concurrent measurement gap patterns are too close to each other in time;
