Allocating resources for shared and non-shared downlink wireless resources
View Patent ↗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.
1. A method performed by a wireless network, the method comprising:
dynamically allocating, by the wireless network to a user equipment (UE) in a cell, a timeslot to a downlink dedicated channel for a call, wherein the timeslot has a lowest available timeslot number in a frame;
monitoring, by the wireless network, the call and reallocating the call to a different timeslot substantially midcall, wherein the different timeslot has a highest quality rank in the cell;
allocating, subsequently by the wireless network, another timeslot for a downlink shared channel in the cell, wherein the another 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, a predetermined number of timeslots for the downlink dedicated channel.
4. The method of claim 1 , wherein the timeslot or the different timeslot is used by another dedicated downlink channel by another UE.
5. The method of claim 1 , wherein the reallocation is performed based on a location of the UE in the cell.
6. The method of claim 1 , wherein the timeslot or the different timeslot is allocated based on intercell interference signals.
7. The method of claim 1 , wherein the timeslot or the different timeslot is allocated based on interference signal code power or signal to interference ratio associated with the timeslot or the different timeslot.
8. The method of claim 1 , wherein the different timeslot is added, substantially midcall, to the 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 time division duplex (TDD) communication.
10. A wireless network characterized in that:
the wireless network is configured to allocate, dynamically to a user equipment (UE) in a cell, a timeslot to a downlink dedicated channel for a call, wherein the timeslot has a lowest available timeslot number in a frame;
the wireless network is configured to monitor the call and configured to reallocate the call to a different timeslot substantially midcall, wherein the different timeslot has a highest quality rank in the cell;
the wireless network is further configured to allocate, subsequently, another timeslot for a downlink shared channel in the cell, wherein the another 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 of claim 10 further characterized in that:
the wireless network is configured to allocate a predetermined number of timeslots for the downlink dedicated channel.
13. The wireless network of claim 10 , wherein the timeslot or the different timeslot is used by another dedicated downlink channel by another UE.
14. The wireless network of claim 10 , wherein the reallocation is performed based on a location of the UE in the cell.
15. The wireless network of claim 10 , wherein the timeslot or the different timeslot is allocated based on intercell interference signals.
16. The wireless network of claim 10 , wherein the timeslot or the different timeslot is allocated based on interference signal code power or signal to interference ratio associated with the timeslot or the different timeslot.
17. The wireless network of claim 10 , wherein the different timeslot is added, substantially midcall, to the timeslot for the call while a power level for the call is held substantially constant.
18. The wireless network of claim 10 , wherein the wireless network is configured to provide time division duplex (TDD) communication.
