Abstract

A method of receiving control information for an uplink in a network includes receiving, by at least one Medium Access Control (MAC) sub-layer in the network, a MAC-e Protocol Data Unit (PDU) from a User Equipment (UE) via an Enhanced Dedicated Channel (E-DCH) which is an uplink transport channel handled by the at least one MAC sub-layer; and acquiring the control information from the received MAC-e PDU, the control information indicating an amount of resources required by the UE. A first format of the MAC-e PDU is received when the control information is included with other information in the MAC-e PDU and a second format of the MAC-e PDU is received when only the control information is included in the MAC-e PDU. The first format of the MAC-e PDU includes a first indicator having a first specific value to indicate that the MAC-e PDU includes the control information.

Claims

1. A method of receiving control information for an uplink in a network, the method comprising:

receiving, by at least one Medium Access Control (MAC) sub-layer in the network, a MAC-e Protocol Data Unit (PDU) from a User Equipment (UE) via an Enhanced Dedicated Channel (E-DCH) which is an uplink transport channel handled by the at least one MAC sub-layer;

and

acquiring the control information from the received MAC-e PDU, the control information indicating an amount of resources required by the UE,

wherein;

a first format of the MAC-e PDU is received when the control information is included with other information in the MAC-e PDU and a second format of the MAC-e PDU is received when only the control information is included in the MAC-e PDU;

the first format of the MAC-e PDU includes a first indicator having a first specific value to indicate that the MAC-e PDU includes the control information; and

a second indicator, which is received via an Enhanced Dedicated Physical Channel (E-DPCCH), has a second specific value to indicate that the second format of the MAC-e PDU includes only the control information.

2. The method of claim 1, further comprising allocating the resources to the UE using the control information.

3. The method of claim 1, wherein the control information comprises scheduling information used by the network.

4. The method of claim 1, wherein the control information comprises buffer status information of the UE.

5. The method of claim 1, wherein the control information comprises transmission power information of the UE.

6. The method of claim 1, wherein the second indicator comprises an Enhanced-Transport Format Combination Indicator (E-TFCI).

7. The method of claim 1, wherein the first indicator comprises a Data Description Indicator (DDI).

8. The method of claim 1, wherein the other information included with the control information in the MAC-e PDU comprises user data.

9. The method of claim 1, wherein the first format of the MAC-e PDU is a piggybacked MAC-e PDU.

10. The method of claim 1, wherein the second format of the MAC-e PDU is a stand alone MAC-e PDU.

11. The method of claim 1, wherein the at least one MAC sub-layer comprises a MAC-e sub-layer and a MAC-es sub-layer.

12. The method of claim 11, wherein the MAC-es sub-layer sits on top of the MAC-e sub-layer.

13. The method of claim 11, wherein the MAC-e sub-layer is located in a base station and the MAC-es sub-layer is located in a serving radio network controller (SRNC).
