Abstract

Systems, methods, and instrumentalities are disclosed for a wireless transmit/receive unit (WTRU) comprising a processor configured to receive a set of gap patterns, and measurement activities associated therewith, wherein each of the gap patterns includes an identifier for the measurement activity to be performed, and measure a signal pursuant to at least one of the gap patterns to obtain a measurement.

First claim

1 .- 22 . (canceled)

23 . A wireless transmit/receive unit (WTRU) comprising:
a memory; and a processor configured to:
send a measurement gap request message associated with a millimeter wave (mmW) measurement, wherein the measurement gap request message includes a measurement gap requirement, and wherein the measurement gap requirement relates to a capability associated with the WTRU or a measurement status associated with the WTRU;
receive a first measurement gap pattern and a second measurement gap pattern, wherein the first measurement gap pattern is associated with a first activity and the second measurement gap pattern is associated with a second activity, and wherein the first measurement gap pattern and the second measurement gap pattern occur in a time period;
perform a measurement associated with a mmW serving cell in accordance with the first measurement gap pattern; and
perform a measurement associated with a first mmW neighbor cell in accordance with the second measurement gap pattern.

24 . The WTRU of claim 23 , wherein the first activity includes a wide beam measurement and the second activity includes a narrow beam measurement, wherein the wide beam measurement and the narrow beam measurement are associated with the mmW serving cell.

25 . The WTRU of claim 23 , wherein the processor is further configured to:
receive a third measurement gap pattern, wherein the third measurement gap pattern is associated with a third activity, and wherein the first, second, and third measurement gap patterns occur in the time period; and perform a measurement associated with a second mmW neighbor cell in accordance with the third measurement gap pattern.

26 . The WTRU of claim 23 , wherein the measurement status is based on at least one of: a measurement result, a number of neighbor mmW cells detected, a location of the WTRU, or a speed of the WTRU.

27 . The WTRU of claim 23 , wherein the capability associated with the WTRU includes at least one of a number of beams supported by the WTRU, a number of phase antenna arrays supported by the WTRU, or a number of simultaneous receive beams supported by the WTRU.

28 . The WTRU of claim 23 , wherein each measurement gap pattern is associated with respective configuration parameters.

29 . The WTRU of claim 23 , wherein at least one of the first measurement gap pattern or the second measurement gap pattern is received by decoding a measurement DCI in a control channel.

30 . The WTRU of claim 23 , wherein at least one of the first measurement gap pattern or the second measurement gap pattern is received by decoding a MAC control element.

31 . A method of evaluating connectivity in a millimeter wave (mmW) system, comprising:
sending a measurement gap request message associated with a millimeter wave (mmW) measurement, wherein the measurement gap request message includes a measurement gap requirement, and wherein the measurement gap requirement relates to a capability associated with the WTRU or a measurement status associated with the WTRU; receiving a first measurement gap pattern and a second measurement gap pattern, wherein the first measurement gap pattern is associated with a first activity and the second measurement gap pattern is associated with a second activity, and wherein the first measurement gap pattern and the second measurement gap pattern occur in a time period; performing a measurement associated with a mmW serving cell in accordance with the first measurement gap pattern; and performing a measurement associated with a first mmW neighbor cell in accordance with the second measurement gap pattern.

32 . The method of claim 31 , wherein the first activity includes a wide beam measurement and the second activity includes a narrow beam measurement, wherein the wide beam measurement and the narrow beam measurement are associated with the mmW serving cell.

33 . The method of claim 31 , further comprising:
receiving a third measurement gap pattern, wherein the third measurement gap pattern is associated with a third activity, and wherein the first, second, and third measurement gap patterns occur in the time period; and performing a measurement associated with a second mmW neighbor cell in accordance with the third measurement gap pattern.

34 . The method of claim 31 , wherein the measurement status is based on at least one of: a measurement result, a number of neighbor mmW cells detected, a location of the WTRU, or a speed of the WTRU.

35 . The method of claim 31 , wherein the capability associated with the WTRU includes at least one of: a number of beams supported by the WTRU, a number of phase antenna arrays supported by the WTRU, or a number of simultaneous receive beams supported by the WTRU.

36 . The method of claim 31 , wherein each measurement gap pattern is associated with respective configuration parameters.

37 . The method of claim 31 , wherein:
at least one of the first measurement gap pattern or the second measurement gap pattern is received by decoding a measurement DCI in a control channel; or at least one of the first measurement gap pattern or the second measurement gap pattern is received by decoding a MAC control element.
