Methods of Measurement of the Electromagnetic and Operational Compatibility of UPCS Devices
synchronized with the timeslot pattern in the frame of the EUT. If necessary, the manufacturer
shall supply means by which to synchronize the interference with the timeslot structure of the
EUT. The interference shall be timed so as to occur centered within the timeslot.
NOTE—A “timeslot” here refers to a subdivision of the EUT frame interval to support multiple users on a single-
carrier frequency using TDMA. It does not refer to the subdivision of a 10 ms interval into multiple frames. For
example, assume that the duration of the EUT frame is 10/X ms, where X is an integer, and each frame is divided into
N timeslots. For the test, there should be N interference pulses per 10 ms interval, not NX pulses. The timing of the
pulses should be arranged such that each of the N timeslots receives one pulse in 10 ms, not one pulse per EUT frame,
unless the EUT frame duration is 10 ms.

Time and spectrum window access procedure
This clause contains tests to verify transmission termination for EUTs that transmit unacknowledged
control and signaling information, and tests for EUTs that do not transmit unacknowledged control and
signaling information. These tests are intended to verify the proper implementation by the EUT of the
requirements of 47CFR15.323(c)(4) to terminate an unacknowledged communications channel within 1 s if
no acknowledgement occurs at initiation, or in 30 s if acknowledgements are lost after initiation, and to
verify (if the EUT transmits a control and signaling channel) the proper implementation by the EUT of the
