Abstract: A wireless transmit/receive unit (WTRU) (e.g., a millimeter WTRU (mWTRU)) may receive a first control channel using a first antenna pattern. The WTRU may receive a second control channel using a second antenna pattern. The WTRU may demodulate and decode the first control channel. The WTRU may demodulate and decode the second control channel. The WTRU may determine, using at least one of: the decoded first control channel or the second control channel, beam scheduling information associated with the WTRU and whether the WTRU is scheduled for an mmW segment. The WTRU may form a receive beam using the determined beam scheduling information. The WTRU receive the second control channel using the receive beam. The WTRU determine, by demodulating and decoding the second control channel, dynamic per-TTI scheduling information related to a data channel associated with the second control channel.

Abstract: A wireless transmit/receive unit (WTRU) is configured to receive an identifier of a beam. The WTRU is configured to measure a downlink quality associated with at least one beam. The WTRU is configured to determine whether the measured downlink quality is below a threshold value. The WTRU is configured to receive at least one control channel transmission using the beam of the identifier in response to a determination that the measured downlink quality is below the threshold value, wherein the beam used to receive the at least one control channel transmission is a same beam used to receive an associated data channel transmission.

Abstract: Methods, devices and systems are provided for performing a random access (RA) procedure. A wireless transmit/receive unit (WTRU) may be configured to receive RA resource sets, where each of the RA resource sets is associated with a node-B directional beam, select an RA resource set from among the RA resource sets, and initiate an RA procedure based on the selected RA resource set. The RA procedure may include selecting multiple preambles which include a preamble for each resource of a plurality of resources corresponding to the selected RA resource set. The WTRU may be configured to sequentially transmit the selected multiple preambles in sequential RA transmissions, and may be configured to receive, from a node-B, in response to the RA transmissions, at least one RA response (RAR), where each of the received at least one RAR corresponds to one of the transmitted multiple preambles.

Abstract: A wireless transmit/receive unit (WTRU) may receive a request to perform directional signal strength measurements and provide location data associated with the WTRU. The WTRU may transmit directional signal strength measurements, based on the request and the location data associated with the WTRU, to facilitate generation of a directional radio environment map (DREM). The WTRU may receive a request to switch to a new transmission and reception beam pair based on the DREM.

Abstract: A wireless transmit/receive unit (WTRU) (e.g., a millimeter WTRU (mWTRU)) may receive a first control channel using a first antenna pattern. The WTRU may receive a second control channel using a second antenna pattern. The WTRU may demodulate and decode the first control channel. The WTRU may demodulate and decode the second control channel. The WTRU may determine, using at least one of: the decoded first control channel or the second control channel, beam scheduling information associated with the WTRU and whether the WTRU is scheduled for an mmW segment. The WTRU may form a receive beam using the determined beam scheduling information. The WTRU receive the second control channel using the receive beam. The WTRU determine, by demodulating and decoding the second control channel, dynamic per-TTI scheduling information related to a data channel associated with the second control channel.
