full_form: Plane Wave Synthesizer
context: calibration and measurement procedures for E-UTRA and NR will be highly similar. All uncertainty factors were judged to be the same. The MU value was thus agreed to be 1.1 dB for up to 3 GHz bands. - For the frequency range 4.2 - 6 GHz, all MU factors including instrumentation related MU were judged to be the same as for the 3 - 4.2 GHz range, and thus the total MU for 4.2 â 6 GHz is the same as for 3 - 4.2 GHz. This assessment was made under the assumption of testing BS designed for licensed spectrum; for unlicensed spectrum the MU may differ. The MU value was thus agreed to be 1.3 dB for 3 â 6 GHz bands. The MU in 4.2 - 6 GHz is valid for BS designed to operate in licensed spectrum. - Based on CATR inputs in clause 9.2.3.4, for the frequency range 24.25 < f < 29.5 GHz the MU was decided to be 1.7 dB. - Based on CATR inputs in clause 9.2.3.4, for the frequency range 37 < f < 43.5 GHz the MU was decided to be 2.0 dB.

description: The Plane Wave Synthesizer (PWS) refers to a specific type of message used in the context of cell broadcast cancellation. The PWS CANCEL REQUEST and PWS CANCEL RESPONSE messages are exchanged between the ng-eNB-CU and ng-eNB-DU to initiate and acknowledge the cancellation of warning messages for a particular area or all cells.
explanation: The text explicitly mentions 'PWS CANCEL REQUEST message' and 'PWS CANCEL RESPONSE message', indicating that PWS is related to signaling messages used in cancelling cell broadcasts. This classifies PWS as a Message entity type.
