Abstract

A packet data communication network includes a plurality of base stations for communicating with mobile stations of a user over packet data traffic channels. Radio transmission control nodes control the operation of the plurality of base stations and a scheduler associated with each of the base stations is configured to allocate a first logical control channel associated with a first user application on a first part of an available radio channel resource, and to allocate a second logical control channel associated with at least a second user application on a second part of the available radio channel resource.

Claims

1. A method in a packet data communication system for allocating user dedicated control channels on an available radio channel resource for transmission of control signals, wherein a first delay sensitive user application and at least a second user application, which is less delay sensitive than the first user application, are assigned for user data transmissions on a packet data traffic channel, the method comprising the steps of:

allocating a first logical control channel associated with the first user application on a first part of the available radio channel resource according to a first predetermined repetition pattern within a superframe structure; and

allocating a second logical control channel associated with the at least second user application on a second part of the available radio channel resource according to a second predetermined repetition pattern within said superframe structure;

wherein said first and second predetermined repetition patterns are selected such that said first and second logical control channels and packet data traffic channel are allocated on a same timeslot within said superframe structure.

2. The method of claim 1, wherein each of said first and second logical control channel is allocated on the same timeslot in one frame at a time.

3. The method of claim 2, wherein each of said first and second logical control channel is allocated on the same timeslot in every second frame of said one frame at a time.

4. The method of claim 2, wherein each of said first and second logical control channel is allocated on the same timeslot in four consecutive frames of said one frame at a time.

5. A packet data communication system comprising:

a plurality of base stations for radio communication with mobile stations of user data over packet data traffic channels;

a radio transmission control node for controlling operation of said plurality of base stations; and

a scheduler associated with each of the plurality of base stations, wherein the scheduler operates to;

allocate a first logical control channel associated with a first user application on a first part of an available radio channel resource according to a first predetermined repetition pattern within a superframe structure; and

allocate a second logical control channel associated with at least a second user application on a second part of the available radio channel resource according to a second predetermined repetition pattern within the superframe structure;

wherein the at least second user application is less delay sensitive than the first user application and the first and second predetermined repetition patterns are selected such that the first and second logical control channels and the packet data traffic channel are allocated on a same timeslot within the superframe structure.

6. The system of claim 5, wherein said radio transmission control node is a base station control node BSC.

7. The system of claim 5, wherein a ratio between said first and second parts of said available radio channel resource is selected based on a network configuration.

8. The system of claim 5, wherein a ratio between said first and second parts of said available radio channel resource is selected based on said first and at least second user applications.

9. The system of claim 5, wherein a ratio between said first and second parts of said available radio channel resource is 50%.

10. A packet data communication system comprising:

a plurality of base stations for radio communication with mobile stations of user data over packet data traffic channels;

a radio transmission control node for controlling operation of the plurality of base stations; and

a scheduler associated with each of the plurality of base stations, wherein the scheduler operates to;

allocate a first logical control channel associated with a first user application on a first part of an available radio channel resource, wherein said first logical control channel is a packet slow associated control channel, PSACCH; and

allocate a second logical control channel associated with at least a second user application on a second part of the available radio channel resource, wherein said second logical control channel is a packet timing advance control channel, PTCCH,

wherein the at least second user application is less delay sensitive than the first user application.

11. The system of claim 10, wherein said scheduler further operates to assign said allocated PSACCH for transmission in an uplink direction of measurement reports.

12. The system of claim 10, wherein said scheduler further operates to assign said allocated PSACCH for transmission in a downlink direction of system-specific information.

13. A packet data communication system comprising:

a plurality of base stations for radio communication with mobile stations of user data over packet data traffic channels;

a radio transmission control node for controlling operation of the plurality of base stations; and

a scheduler associated with each of the plurality of base stations, wherein the scheduler operates to;

allocate a first logical control channel associated with a first user application on a first part of an available radio channel resource according to a first predetermined repetition pattern within a superframe structure; and

allocate a second logical control channel associated with at least a second user application on a second part of the available radio channel resource according to a second predetermined repetition pattern within the superframe structure,

wherein the at least second user application is less delay sensitive than the first user application, and wherein said scheduler further operates to select said first and second predetermined repetition patterns such that said first and second logical control channels and packet data traffic channel are allocated on a same timeslot within said superframe structure.

14. The system of claim 13, wherein said scheduler further operates to allocate each of said first and second logical control channel on timeslot in one frame at a time.

15. The system of claim 14, wherein said scheduler further operates to allocate each of said first and second logical control channel on timeslot in every second frame of said one frame at a time.

16. The system of claim 14, wherein said scheduler further operates to allocate each of said first and second logical control channel on timeslot in four consecutive frames of said one frame at a time.
