Abstract

A method for assigning physical channels to time slots in a hybrid wireless time division multiple access/code division multiple access communication system begins by providing physical channels for assignment. A set of time slots is provided for potential assignment. The set of time slots is arranged into a sequence based on a quality of each of the set of time slots. The provided physical channels are assigned to the time slots in a time slot order of the sequence.

Claims

1. A method for assigning physical channels to time slots in a hybrid wireless time division multiple access/code division multiple access communication system, comprising the steps of:

providing physical channels for assignment;

providing a set of time slots for potential assignment;

arranging the set of time slots into a sequence based on a quality of each of the set of time slots; and

assigning the provided physical channels to the time slots in a time slot order of the sequence.

2. The method of claim 1, wherein the provided physical channels are physical channels of a user service.

3. The method of claim 1, wherein the provided physical channels are physical channels of a coded composite transport channel.

4. The method of claim 1, wherein the quality of each time slot is based on in part an interference measurement and an allowed number of the provided physical channels to be assigned to that channel.

5. The method of claim 1 for use in downlink physical channel assignments, wherein the quality of each time slot is based on in part a transmit power of that slot and an allowed number of the provided physical channels to be assigned to that time slot.

6. A radio network controller (RNC) for use in a hybrid wireless time division multiple access/code division multiple access communication system, the RNC assigning a set of physical channels to a set of time slots, the RNC comprising:

a radio resource management device configured to arrange the set of time slots into a sequence based on a quality of each of the set of time slots and configured to assign the set of physical channels to the time slots in a time slot order of the sequence.

7. The RNC of claim 6, wherein the set of physical channels are physical channels of a user service.

8. The RNC of claim 6, wherein the set of physical channels are physical channels of a coded composite transport channel.

9. The RNC of claim 6, wherein the quality of each time slot is based on in part an interference measurement and an allowed number of the provided physical channels to be assigned to that channel.

10. The RNC of claim 6 for use in downlink physical channel assignments, wherein the quality of each time slot is based on in part a transmit power of that slot and an allowed number of the provided physical channels to be assigned to that physical channel.

11. A radio network controller (RNC) for use in a hybrid wireless time division multiple access/code division multiple access communication system, the RNC assigning a set of physical channels to a set of time slots, the RNC comprising:

arranging means for arranging the set of time slots into a sequence based on a quality of each of the set of time slots; and

assigning means for assigning the set of physical channels to the time slots in a time slot order of the sequence.

12. The RNC of claim 11, wherein the set of physical channels are physical channels of a user service.

13. The RNC of claim 11, wherein the set of physical channels are physical channels of a coded composite transport channel.

14. The RNC of claim 11, wherein the quality of each time slot is based on in part an interference measurement and an allowed number of the provided physical channels to be assigned to that channel.

15. The RNC of claim 11 for use in downlink physical channel assignments, wherein the quality of each time slot is based on in part a transmit power of that slot and an allowed number of the provided physical channels to be assigned to that time slot.
