Abstract
Systems and methods are disclosed for a WTRU to operate using multiple schedulers. The WTRU may exchange data with the network over more than one data path, such that each data path may use a radio interface connected to a different network node and each node may be associated with an independent scheduler. For example, a WTRU may establish a RRC connection between the WTRU and a network. The RRC connection may establish a first radio interface between the WTRU and a first serving site of the network and a second radio interface between the WTRU and a second serving site of the network. The RRC connection may be established between the WTRU and the MeNB and a control function may be established between the WTRU and the SCeNB. The WTRU may receive data from the network over the first radio interface or the second radio interface.

Claim
A method for a wireless transmit receive unit (WTRU), the method comprising:
the WTRU establishing a radio resource control (RRC) connection, wherein the RRC connection is common between at least a first medium access control (MAC) instance associated and a second MAC instance; the WTRU receiving first data associated with a first data radio bearer DRB via the first MAC instance, the first MAC instance being associated transmissions to and/or from a macro cell; and the WTRU receiving second data associated with a second DRB via the second MAC instance, the second MAC instance being associated with transmissions to and/or from one or more small cells.
2. The method as in claim 1, wherein at least a third DRB is split between the first and second MAC instances below a packet data convergence protocol (PDCP) layer.
3. The method as in claim 1, wherein a single RRC entity at the WTRU is configured to configured each of the first and second MAC instances.
4. The method as in claim 1, wherein the macro cell is provided by a first type of radio access node associated with a first cell type and the one or more small cells are provided by a second type of radio access node associated with a second cell type.
5. A wireless transmit receive unit (WTRU) comprising a processor configured to:
establish a radio resource control (RRC) connection, wherein the RRC connection is common between at least a first medium access control (MAC) instance associated and a second MAC instance; receive first data associated with a first data radio bearer (DRB) via the first MAC instance, the first MAC instance being associated transmissions to and/or from a macro cell; and receive second data associated with a second DRB via the second MAC instance, the second MAC instance being associated with transmissions to and/or from one or more small cells.
