Abstract
A wireless mobile device is configured to set up communications via wireless links with wireless base stations of a cellular communication system and to obtain information indicative of shadow prices of said wireless base stations via wireless transmissions. Each of the wireless base stations has a corresponding shadow price. The wireless mobile device is configured to make a select one of the wireless base stations for a wireless link with the wireless mobile device based on the information indicative of the shadow prices.
Claims20
An apparatus, comprising:
- a wireless mobile device being configured to set up communications via wireless links with wireless base stations of a cellular communication system and to obtain information indicative of shadow prices of said wireless base stations via wireless transmissions, each of the wireless base stations having a corresponding shadow price;
- and
- wherein the wireless mobile device is configured to select one of the wireless base stations for a wireless link with the wireless mobile device based on the information indicative of the shadow prices.
A method, comprising:
- assigning shadow prices to a plurality of wireless base stations of a cellular communication system such that each wireless base station has a corresponding shadow price, each shadow price being indicative of a relative transmission power load on the corresponding wireless base station;
- and
- making candidate assignments of communication links between wireless communication devices and the wireless base stations based on the assigned shadow prices.
A system, comprising:
- a plurality of wireless base stations located in a contiguous spatial coverage region of a cellular communication system, each wireless base station being configured to generate a coverage pilot beam to enable wireless mobile devices to set up wireless communication links with the generating wireless base station;
- and
- wherein the wireless base stations are configured to transmit data to wireless mobile devices to cause a portion of the wireless mobile devices to select ones of the wireless base stations for wireless communication links in a manner that reduces power load imbalances between the wireless base stations;
- and
- wherein the transmitted data is indicative of a set of shadow prices, each of the wireless base stations is associated with a corresponding one of the shadow prices.
