Reconfiguration and handover procedures for fuzzy cells

Abstract

A wireless transmit/receive unit (WTRU) for providing dual connectivity. The WTRU may receive a reconfiguration message from a source eNode-B that may identify a resource. The WTRU may send a reconfiguration complete message to the source eNode-B that may indicate that the WTRU may be configured to use the resource. The WTRU may maintain a first connection the source eNode-B using a component carrier while establishing a second connection to the target eNode-B using the resource.

What is claimed: 
     
         1 . An apparatus for providing dual connectivity for a wireless transmit/receive unit (WTRU), the apparatus comprising:
 a processor, the processor being configured to:
 send an allocation request to a target eNode-B to request a resource for the WTRU; 
 receive an acknowledgement message from the target eNode-B indicating that the resource has been allocated for the WTRU; and 
 send a reconfiguration message to the WTRU to instruct the WTRU to maintain a first connection to the source eNode-B using a component carrier while establishing a second connection to the target eNode-B using the resource. 
   
     
     
         2 . The apparatus of  claim 1 , wherein the component carrier is a first component carrier and the resource is a second component carrier. 
     
     
         3 . The apparatus of  claim 1 , wherein the processor is further configured to receive a reconfiguration complete message from the WTRU indicating that the WTRU is configured to use the resource. 
     
     
         4 . The apparatus of  claim 1 , wherein the processor is further configured to notify the target eNode-B that the WTRU is configured to use the resource. 
     
     
         5 . The apparatus of  claim 1 , wherein the processor is further configured to identify the resource. 
     
     
         6 . The apparatus of  claim 1 , wherein the processor is further configured to receive a measurement report from the WTRU. 
     
     
         7 . The apparatus of  claim 1 , wherein the processor is further configured to receive a recommendation message from the target eNode-B that identifies the resource. 
     
     
         8 . An apparatus for providing dual connectivity for a wireless transmit/receive unit (WTRU), the apparatus comprising:
 a processor, the processor being configured to:
 receive an allocation request from a source eNode-B that requests a resource for the WTRU; 
 send an acknowledgement message to the source eNode-B indicating that the resource has been allocated for the WTRU; and 
 establishing a connection to the WTRU using the resource such that the WTRU can also maintain a connection to the source eNode-B using a component carrier. 
   
     
     
         9 . The apparatus of  claim 8 , wherein the acknowledgement message further indicates that the resource can be used to split data between the source eNode-B and the target eNode-B. 
     
     
         10 . The apparatus of  claim 8 , wherein the component carrier is a first component carrier and the resource is a second component carrier. 
     
     
         11 . The apparatus of  claim 8 , wherein the processor is further configured to receive a reconfiguration complete message from the source eNode-B indicating that the WTRU is configured to use the resource. 
     
     
         12 . The apparatus of  claim 1 , wherein the allocation request identifies the resource. 
     
     
         13 . The apparatus of  claim 1 , wherein the processor is further configured to send a recommendation message to the source eNode-B that identifies the resource. 
     
     
         14 . A wireless transmit/receive unit (WTRU) for providing dual connectivity, the WTRU comprising:
 a processor, the processor being configured to:
 receive a reconfiguration message from a source eNode-B that identifies a resource; 
 sending a reconfiguration complete message to the source eNode-B that indicates that the WTRU is configured to use the resource; and 
 maintaining a first connection to the source eNode-B using a component carrier while establishing a second connection to the target eNode-B using the resource. 
   
     
     
         15 . The WTRU of  claim 14 , wherein the component carrier is a first component carrier and the resource is a second component carrier. 
     
     
         17 . The WTRU of  claim 14 , wherein the processor is further configured to receive data via the first component carrier and the second component carrier. 
     
     
         18 . The WTRU of  claim 14 , wherein the processor is further configured to establish the second connection to the target eNode-B using the resource by establishing the second connection via a random access procedure. 
     
     
         19 . The WTRU of  claim 14 , wherein the processor is further configured to send a measurement report to the source eNode-B. 
     
     
         20 . The WTRU of  claim 14 , wherein the processor is further configured to receive the reconfiguration message via medium access control (MAC) or a radio resource control (RRC) signaling.
