Distributed resource management for enhanced dedicated channel
View Patent ↗The present invention provides methods for distributed resource management for enhanced dedicated channel. One method of communication with at least one base station includes determining at least one short-term entity associated with the at least one base station and providing the at least one short-term entity to a radio network controller. Another method includes receiving at least one short-term entity associated with the at least one base station and allocating at least one long-term resource based upon the at least one short-term entity.
1. A method comprising:
performing, in at least one base station, at least one measurement of uplink signals from a plurality of mobile units;
determining, at said at least one base station, a plurality of short-term entities based on said at least one measurement, each short-term entity being associated with one of the mobile units, said at least one base station being configured to allocate short-term resources to each of the mobile units based on said short-term entity to approach a selected level of a rise-over-thermal caused by the mobile units;
determining, at said at least one base station, at least one long-term entity associated with the plurality of mobile units based on said at least one measurement; and
providing said short-term entities and said at least one long-term entity to a radio network controller that is configured to allocate long term resources based on said plurality of short-term entities and said at least one long-term entity.
2. The method of claim 1 , wherein determining a plurality of short-term entities comprises determining at least one of a legacy dedicated channel fraction of a received total wideband power, a legacy dedicated channel fraction of a received signal strength indication, an average normalized received chip energy, a radio channel condition, and an individual normalized received chip energy.
3. The method of claim 1 , comprising establishing at least one wireless communication link between at least one base station and at least one mobile unit.
4. The method of claim 3 , wherein establishing the at least one wireless communication link comprises establishing at least one uplink dedicated channel between the at least one base station and the at least one mobile unit and modifying a data rate or time scheduling of the mobile units to satisfy a rise-over-thermal tolerance requirement.
5. The method of claim 1 , comprising allocating said at least one short-term resource to account for silences in voice communication.
6. The method of claim 5 , wherein allocating the at least one short-term resource comprises dynamically allocating at least one of a voice communication bandwidth and a data communication bandwidth so that the data communication bandwidth is increased when the voice communication bandwidth decreases and the data communication bandwidth is decreased when the voice communication bandwidth increases.
7. The method of claim 5 , wherein allocating the at least one short-term resource comprises allocating the at least one short-term resource on a timescale of between one to fifteen time slots (about 0.667 and ten milliseconds in UMTS) or one to sixteen power control groups (about 1.25 ms to twenty milliseconds in CDMA2000).
8. The method of claim 5 , wherein allocating the at least one short-term resource comprises allocating the at least one short-term resource to attempt to maximize capacity of a wireless telecommunications system by approaching a maximum tolerable level of the rise-over-thermal caused by the mobile units.
9. The method of claim 8 , wherein allocating the at least one short-term resource comprises dynamically controlling interference from at least one of mobile unit to control the rise-over-thermal caused by the mobile units.
10. The method of claim 1 , wherein determining said at least one long-term entity comprises determining at least one long-term entity indicating an aggregate power received from the plurality of mobile units.
11. A method, comprising:
receiving, at a network controller, a plurality of short-term entities associated with each of a plurality of mobile units and at least one long-term entity associated with the plurality of mobile units, the plurality of short-term entities and said at least one long term entity being determined based on at least one measurement of uplink signals from the mobile units performed by at least one base station, said at least one base station being configured to allocate short-term resources to each of the mobile units based on said short-term entity associated with a corresponding mobile unit to approach a selected level of a rise-over-thermal caused by the mobile units; and
allocating at least one long-term resource based upon the a plurality of short-term entities and said at least one long-term entity.
12. The method of claim 11 , wherein receiving the at least one short-term entity comprises receiving at least one of a legacy dedicated channel fraction of a received total wideband power or received signal strength indication, an average normalized received chip energy, a radio channel condition, and an individual normalized received chip energy.
13. The method of claim 11 , wherein allocating the at least one long-term resource comprises determining whether or not to admit a mobile unit depending on whether the short-term entity indicates that a saturation stage has been reached by said at least one base station.
14. The method of claim 11 , wherein allocating the at least one long-term resource comprises allocating the at least one long-term resource on a timescale of approximately 100 milliseconds to a few seconds.
15. The method of claim 11 , comprising terminating at least one wireless communication link between at least one base station and at least one mobile unit.
16. The method of claim 15 , wherein terminating the at least one wireless communication link comprises terminating the at least one wireless communication link based upon at least one of a poor radio channel condition, a system overload, and a handoff.
17. The method of claim 11 , wherein receiving said at least one long-term entity comprises receiving at least one long-term entity indicating an aggregate power received from the plurality of mobile units.
