Abstract

A network server and method thereof are provided. The method performed by a network server includes receiving a first data from a first radio frame on a UL DPDCH, despreading the first data with a fixed spreading factor, de-rate matching the despreaded first data with a plurality of de-rate matching schemes, and determining a transport format of the first data that is being used based on all decoded data.

Claims

1. A method, performed by a network server, comprising:

receiving a first data from an uplink dedicated data physical channel (UL DPDCH);

despreading the first data with a plurality of spreading factors; and

determining a transport format of the first data that is being used based on all despreaded data,

wherein the first data has a variable data rate.

2. The method of claim 1, further comprising:

receiving a second radio frame on an uplink dedicated control physical channel (UL DPCCH), wherein the second radio frame contains only a pilot data, a feedback indication (FBI) data, and a transmit power control (TPC) data.

3. The method of claim 1, wherein the determining step comprises:

determining accuracy for each despreaded data based on an error detection scheme; and

determining the transport format of the first data based on the accuracy.

4. The method of claim 1, wherein the first data is a circuit switched data.

5. A method, performed by a network server, comprising:

receiving a first data from a first radio frame on a UL DPDCH;

despreading the first data with a fixed spreading factor;

de-rate matching the despreaded first data with a plurality of de-rate matching schemes; and

determining a transport format of the first data that is being used based on all decoded data.

6. The method of claim 5, wherein the despreaded first data includes a repeated data pattern.

7. The method of claim 5, wherein the de-rate matching step comprises de-rate matching the despreaded first data based on a repetition pattern.

8. The method of claim 5, wherein the determining step comprises:

determining accuracy for each decoded data based on an error detection scheme; and

determining the transport format of the first data based on the accuracy.

9. The method of claim 5, further comprising:

receiving a second radio frame on a UL DPCCH, wherein the second radio contains only a pilot data, a feedback indication (FBI) data, and a transmit power control (TPC) data.

10. The method of claim 5, wherein the first data is a circuit switched data.

11. A method performed by a mobile communications device, comprising:

generating a radio frame which only consists of a pilot data, a feedback indication (FBI) data, and a transmit power control (TPC) data; and

transmitting the radio frame on an uplink dedicated control physical channel (UL DPCCH).

12. The method of claim 11, further comprising:

rate matching a first data to a fixed data length;

spreading the rate matched first data with a fixed spreading factor; and

transmitting the spreaded data on a UL DPDCH.

13. A method performed by a mobile communications device, comprising:

rate matching a first data to a fixed data length;

spreading the rate matched first data with a fixed spreading factor; and

transmitting the spreaded data on a UL DPDCH.

14. The method of claim 13, further comprising:

transmitting a radio frame on an uplink dedicated control physical channel (UL DPCCH);

wherein the radio frame only consists of a pilot data, a feedback indication (FBI) data, and a transmit power control (TPC) data.
