Abstract

The embodiments of the present invention provide for methods, devices, and systems adapted to enable an eNodeB to instruct a user equipment/device (UE) to adjust its current discontinuous reception (DRX) state, cycle level or cycle state, based on one or more reserved bit values of a MAC LCID.

Claims

1. A method of discontinuous reception (DRX) management, the method comprising the steps of:

receiving by a user equipment (UE), a Medium Access Control (MAC) control element having at least one reserve bit location;

testing by the UE of the received MAC control element for one or more reserved bit values; and

setting a DRX state based on the one or more reserved bit values.

2. The method of discontinuous reception (DRX) management of claim 1 wherein the setting of the DRX state effects a change in at least one of a DRX cycle state and a DRX cycle state level.

3. The method of discontinuous reception (DRX) management of claim 1 wherein the MAC control element is a MAC Link Control Identifier (LCID).

4. A system comprising:

a first node comprising;

a DRX controller module adapted to configure a Medium Access Control (MAC) control element comprising at least one reserve bit location having a value indicating a DRX state for a receiving user equipment (UE); and

a communication interface module adapted to transmit the MAC control element comprising at least one reserve bit having a value indicating a DRX state; and

the UE comprising;

a communication interface module adapted to receive the MAC control element comprising at least one reserve bit location having a value indicating the DRX state; and

a DRX execution module adapted to;

test the received MAC control element for one or more reserved bits having reserved bit values; and

set the DRX state of the UE based on one or more reserved bit values.

5. The system of claim 4 wherein the first node is an eNodeB.

6. The system of claim 4 wherein the indicated DRX state effects a change in at least one of a DRX cycle state and a DRX cycle state level.

7. The system of claim 4 wherein the MAC control element is a MAC Link Control Identifier (LCID).

8. The system of claim 4 wherein the first node is an eNodeB.

9. A user equipment device in a radio access network, said device comprising:

a communication interface processing module configured to receive a Medium Access Control (MAC) control element comprising at least one reserve bit having a value indicating a DRX cycle level; and

a DRX execution processing module configured to;

test the received MAC control element for one or more reserved bits having reserved bit values; and

set the DRX state based on one or more reserved bit values.

10. The user equipment device in a radio access network of claim 9 wherein the setting of the DRX state effects a change in at least one of a DRX cycle state and a DRX cycle state level.

11. The user equipment device in a radio access network of claim 9 wherein the MAC control element is a MAC Link Control Identifier (LCID).
