Abstract
Methods and apparatuses for millimeter wave (mmW) beam acquisition are disclosed. An apparatus may include a processor and a transceiver configured to receive configuration information from a first network node using a first radio access technology (RAT). The configuration information may include an index associated with a beam of a second network node and timing information corresponding to the first RAT. The second network node may use a second RAT. The apparatus may be further configured to transmit a measurement report to the first network node that includes a measurement of the beam and index associated with the beam of the second network node.

5. The WTRU of claim 1, wherein the processor and transceiver are further configured to receive second configuration information and, in response to the received second configuration information, to connect to a base station associated with the second network node.
6. The WTRU of claim 5, wherein the processor and transceiver are configured to simultaneously maintain connections to both the first network node and the second network node.
7. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
receiving, by the WTRU from a first network node using a first radio access technology (RAT), configuration information, wherein the configuration information includes an index associated with a beam of a second network node using a second RAT and an indication of a frame and subframe of a transmission from the first network node; and transmitting a measurement report that includes a measurement of the beam of the second network node at the indicated frame and subframe of the transmission from the first network node, and the index associated with the beam of the second network node.
8. The method of claim 7, wherein the configuration information further includes a plurality of indices associated with a respective plurality of beams of the second network node, and wherein the measurement report includes the measurement and the index of one of the plurality of beams of the second network node with a highest signal strength.
9. The method of claim 7, wherein the first RAT is a long term evolution RAT and the configuration information is received in a radio resource control (RRC) message.
10. The method of claim 9, wherein the measurement report is transmitted on a physical uplink shared channel (PUSCH).
11. The method of claim 7 further comprising receiving second configuration information and, in response to receiving second configuration information, connecting to a base station associated with the second network node.
12. The method of claim 11 further comprising simultaneously maintaining connections to both the first network node and the second network node.
