Abstract
A method for communication in a wireless telecommunication system is provided. The method includes assigning a first cell of a first network node to a first timing advance group (TAG) of a user equipment (UE) and assigning a second cell of a second network node to a second TAG of the UE, wherein the second network node has a separate MAC (medium access control) scheduler from the first network node, and wherein the UE is able to transmit data on both the first and the second cell.
Claims18
A method for communication in a wireless telecommunication system, the method comprising:
- signaling, to a user equipment (UE), a timing advance group (TAG) comprising at least a first cell originating from a first network node and a second cell originating from a second network node separate from the first network node;
- wherein the second network node has a separate MAC (medium access control) scheduler from the first network node, wherein the second network node is an evolved Node B (eNB) having its own radio resource management (RRM) functionality.
A first network node comprising:
- a processor configured to signal, to a user equipment (UE), a timing advance group (TAG) comprising at least a first cell originating from the first network node and a second cell originating from a second network node separate from the first network node,
- wherein the second network node has a separate medium access control (MAC) scheduler from the first network node, wherein the second network node is an evolved Node B (eNB) having its own radio resource management (RRM) functionality.
A user equipment (UE) comprising:
- a processor configured to receive a timing advance group (TAG) comprising at least a first cell originating from a first network node and a second cell originating from a second network node separate from the first network node,
- wherein the second network node has a separate medium access control (MAC) scheduler from the first network node, wherein the second network node is an evolved Node B (eNB) having its own radio resource management (RRM) functionality.
