Abstract

A wireless network dynamically allocating a timeslot to a downlink dedicated channel to a user equipment (UE) in a cell is disclosed. A call may be reallocated a different timeslot midcall where the different timeslot has a highest quality rank in the cell. The timeslot may then be allocated to a downlink shared channel in the cell. The allocation of the timeslot to the downlink dedicated channel may be prioritized over the allocation of the timeslot to the downlink shared channel.

Claims

1. A method performed by a wireless network device, the method comprising:

dynamically allocating, dynamically by the wireless network device to a user equipment (UE) in a cell, a first timeslot to a downlink dedicated channel for a call, wherein the first timeslot has a lowest available timeslot number in a frame associated with a plurality of pre-configured timeslot numbers;

monitoring, by the wireless network device, the call and reallocating the call to a different second timeslot substantially midcall during the call, wherein the different second timeslot has a highest high quality rank in the cell during the frame;

allocating, subsequently by the wireless network device, another a third timeslot for a downlink shared channel in the cell, wherein the another third timeslot has a highest available timeslot number; and

wherein allocation of timeslots to the downlink dedicated channel are prioritized over allocation of timeslots to the downlink shared channel.

2. The method of claim 1, wherein the timeslot or the different timeslot have a dynamically assigned maximum number.

3. The method of claim 1 further comprising:

allocating, by the wireless network device, a predetermined number of timeslots for the downlink dedicated channel.

4. The method of claim 1, wherein the first timeslot or the different second timeslot is currently used by another dedicated downlink dedicated channel by another UE.

5. The method of claim 1, wherein the reallocation is performed based on a location of the UE in the a cell.

6. The method of claim 1, wherein the first timeslot or the different second timeslot is allocated based on intercell interference signals.

7. The method of claim 1, wherein the first timeslot or the different second timeslot is allocated based on interference signal code power or signal to interference ratio associated with the first timeslot or the different second timeslot.

8. The method of claim 1, wherein the different second timeslot is added, substantially midcall, to the first timeslot for the call while a power level for the call is held substantially constant.

9. The method of claim 1, wherein the wireless network is configured to provide first timeslot, the second timeslot, or the third timeslot are part of time division duplex (TDD) communication.

10. A wireless network characterized in that device comprising:

the wireless network isone or more processors configured to allocate, dynamically to a user equipment (UE) in a cell, a first timeslot to a downlink dedicated channel for a call, wherein the first timeslot has a lowest available timeslot number in a frame associated with a plurality of pre-configured timeslot numbers;

the wireless network isthe one or more processors further configured to monitor the call and configured to reallocate the call to a differentsecond timeslot substantially midcallduring the call, wherein the differentsecond timeslot has a highesthigh quality rank in the cellduring the frame;

the wireless network is one or more processors are further configured to allocate, subsequently, another a third timeslot for a downlink shared channel in the cell, wherein the another third timeslot has a highest available timeslot number; and

wherein allocation of timeslots to the downlink dedicated channel are prioritized over allocation of timeslots to the downlink shared channel.

11. The wireless network of claim 10, wherein the timeslot or the different timeslot have a dynamically assigned maximum number.

12. The wireless network device of claim 10 further characterized in that comprising:

the wireless network is one or more processors are further configured to allocate a predetermined number of timeslots for the downlink dedicated channel.

13. The wireless network device of claim 10, wherein the first timeslot or the different second timeslot is currently used by another dedicated downlink dedicated channel by another UE.

14. The wireless network device of claim 10, wherein the reallocation is performed based on a location of the UE in the a cell.

15. The wireless network device of claim 10, wherein the first timeslot or the different second timeslot is allocated based on intercell interference signals.

16. The wireless network device of claim 10, wherein the first timeslot or the different second timeslot is allocated based on interference signal code power or signal to interference ratio associated with the first timeslot or the different second timeslot.

17. The wireless network device of claim 10, wherein the different second timeslot is added, substantially midcall, to the first timeslot for the call while a power level for the call is held substantially constant.

18. The wireless network device of claim 10, wherein the wireless network is configured to provide first timeslot, the second timeslot, or the third timeslot are part of time division duplex (TDD) communication.
