Method and apparatus for a millimeter wave communication system

A method performed by a wireless transmit/receive unit (WTRU), the method comprising:

• receiving, by the WTRU, a plurality of signals, wherein the plurality of signals is swept over time using a respective plurality of beams, wherein each signal of the plurality of signals includes a sequence based on an index of a respective one of the plurality of beams;
• measuring, by the WTRU, a first signal of the plurality of signals;
• and
• transmitting, by the WTRU, a measurement report including the measurement of the first signal of the plurality of signals and the index of a respective one of the plurality of beams.

A network node comprising:

• a processor;
• and
• a transceiver;
• the transceiver configured to transmit a plurality of signals using a respective plurality of beams, wherein the plurality of signals is swept over time using the respective plurality of beams, wherein each signal includes a sequence;
• the processor configured to produce each sequence based on an index of a respective one of the plurality of beams;
• and
• the transceiver configured to receive a measurement report including a measurement of a first signal of the plurality of signals and the index of a respective one of the plurality of beams.
