Abstract

A method for transmitting information includes by a NodeB, receiving a message for setting up/reconfiguring a shared Enhanced Dedicated Channel (E-DCH) transmission channel from a Radio Network Controller (RNC); and setting up the shared E-DCH transmission channel according to parameters in the message, and exchanging information with the RNC through an established shared E-DCH transmission bearer.

Claims

1. A method for transmitting information, comprising:

receiving, by a NodeB, a message for setting up a shared enhanced dedicated channel (E-DCH) from a radio network controller (RNC), wherein the shared E-DCH is an E-DCH shared among a plurality of user equipments (UEs) and seized by one of the UEs via competition; and

setting up, by the NodeB, the shared E-DCH according to the message;

wherein the message comprises the following parameters that are needed when a UE performs a random access procedure through the shared E-DCH;

a signature list;

a relevant E-DCH physical layer parameter;

a transmission channel parameter; and

a transmission bearer parameter;

and wherein the signature list is transmitted to the NodeB by the RNC in a same manner as transmitting a preamble signature in a physical random access channel (PRACH).

2. The method of claim 1, further comprising:

returning, by the NodeB, information about the shared E-DCH to the RNC, wherein the returned information comprises at least one of a transmission layer address and a binding ID.

3. The method of claim 1, further comprising:

converting, by the NodeB, data sent by a UE into a frame protocol (FP) frame carrying a UE identification (ID) of the UE, and

sending, by the NodeB, the FP frame to the RNC through the shared E-DCH.

4. The method of claim 1, wherein the signature list comprises an index in a table in a protocol, the index corresponding to the signature list.

5. The method of claim 1, wherein

the relevant E-DCH physical layer parameter comprises at least one of:

E-DPCH information, E-DCH FDD Information and F-DPCH Information.

6. The method of claim 5, wherein the E-DPCH information comprises at least one of the following items:

a maximum set of an E-DPDCH, a puncture limit, E-TFCS Information, E-TTI, an E-DPCC power offset and HARQ Info for E-DCH.

7. The method of claim 1, wherein the transmission bearer parameter comprises at least one of:

a binding identification (ID),

a transport layer address,

a common transport channel ID,

a transport format set, and

TNL QoS.

8. A system for transmitting information, comprising:

a radio network controller (RNC); and

a NodeB;

wherein the RNC is configured to send a message for setting up a shared enhanced dedicated channel (E-DCH) to the NodeB, wherein the shared E-DCH is an E-DCH shared among a plurality of user equipments (UEs) and seized by one of the UEs via competition; and

the NodeB is configured to set up the shared E-DCH according to the message sent by the RNC;

wherein the message comprises the following parameters that are needed when a UE performs a random access procedure through the shared E-DCH;

a signature list, which is transmitted to the NodeB by the RNC in a same manner as transmitting a preamble signature in a physical random access channel (PRACH),

a relevant physical layer parameter,

a transmission channel parameter, and

a transmission bearer parameter.

9. The system of claim 8, wherein:

the NodeB is further configured to obtain an E-DCH frame protocol (FP) frame that carries a UE identification (ID) of the UE and corresponds to data received from the UE, and to send the E-DCH FP frame, which carries the UE ID, through the shared E-DCH to the RNC; and

the RNC is further configured to receive the E-DCH FP frame sent by the NodeB and resolve the received E-DCH FP frame to obtain the UE ID.

10. A NodeB, comprising:

a transceiver, configured to receive a message for setting up a shared enhanced dedicated channel (E-DCH) from a radio network controller (RNC), wherein the shared E-DCH is an E-DCH shared among a plurality of user equipments (UEs) and seized by one of the UEs via competition; and

a channel setup unit, configured to set up the shared E-DCH according to the message received by the transceiver;

wherein the message comprises the following parameters that are needed when a UE performs a random access procedure through the shared E-DCH;

a signature list, which is transmitted to the NodeB by the RNC in a same manner as transmitting a preamble signature in a physical random access channel (PRACH),

a relevant physical layer parameter,

a transmission channel parameter, and

a transmission bearer parameter.

11. The NodeB of claim 10, further comprising:

an identification unit, configured to obtain an E-DCH frame protocol (FP) frame that carries a UE ID of the UE and corresponds to data received from the UE, and to control the transceiver to send the E-DCH FP frame to the RNC through the shared E-DCH.

12. The NodeB of claim 10, wherein the relevant E-DCH physical layer parameter comprises at least one of:

E-DPCH information, E-DCH FDD Information and F-DPCH Information.

13. The NodeB of claim 12, wherein the E-DPCH information comprises at least one of a maximum set of an E-DPDCH, a puncture limit, E-TFCS Information, E-TTI, an E-DPCC power offset and HARQ Info for E-DCH.

14. The NodeB of claim 10, wherein the transmission bearer parameter comprises at least one of a binding ID, a transport layer address, a common transport channel ID, a transport format set and TNL QoS.
