When the MP interval timer expires, a value of the PMP timer is set to a predetermined time duration and the receiver filter is disabled.

If the vehicle remains stationary, start the measurement of the test period

The modulation waveforms used to modulate the light sources (12a, 12b) and corresponding demodulation waveforms used to demultiplex the composite signal are symmetrically timed about a center point for each of the measurement periods.

The apparatus may be an access point (AP) in a BSS which includes a measurement period (MP) interval timer, a promiscuous measurement period (PMP) timer and a receiver filter.

At least one average signal strength value of the signal measurement data received during the measurement period is computed.

During this QCM period, the data rate cannot change.

The secondary station determines average channel characteristics over a measurement period.

In particular, the reduced measurement period can be less than 100 milliseconds.

The transmission frame may include an explicit instruction for the media idle measurement period or may cause the media idle measurement period by simulating a collision on the communications media.

Disclosed is a method for adaptive adjustment of the measurement period of a neighbouring cell.

For a E-DCH transmission, a reduced measurement period can be utilized in order to report a UPH measurement.

When the data burst spans multiple measurement periods and the data burst is split at each measurement period boundary.

A laser distance measurement unit successively outputs laser distance measurement data during a measurement period while the flying body is flying in a rectilinear flying path (32).

Moreover, the user equipment (140) measures (207) said at least one measurement quantity on at least the second cell on the second carrier over the first measurement period.

The timing deciding means assigns the same different frequency measuring timing to at least two mobile stations belonging to the same multicast group.
