Abstract

A technique for wireless communications in a wireless system including: receiving, by a wireless device, a request to perform a pathloss reference signal (PLRS) measurement procedure in an unlicensed band, wherein the wireless device is configured to accumulate a first number of PLRS measurements within a PLRS switching period to perform the PLRS measurement procedure, wherein the first number of PLRS measurements is more than one, measuring, by the wireless device, a second number of PLRS signals during the PLRS switching period, wherein the second number is less than the first number of PLRS measurements within the PLRS switching period, determining, by the wireless device, to extend the PLRS switching period, and listening, by the wireless device, for a PLRS signal during the extended PLRS switching period.
