METHODS AND APPARATUS FOR DYNAMIC IDENTIFICATION (ID) ASSIGNMENT IN WIRELESS NETWORKS
First Claim
1. A method of providing a data service to a wireless device from a serving device, the method comprising:
- receiving a first message from the wireless device;
determining a first element based at least in part on one or more first transmission channel path characteristics of the first message;
associating the data service to the first element; and
transmitting the associated data service and the first element.

Abstract
Methods and apparatus that reduce user identification overhead for communications. In one aspect of the invention, a reciprocal transmission channel characteristic (e.g., the channel impulse response) is used to derive shared and anonymous user identification between two wireless devices. In one embodiment, subscription-less data transmissions are broadcast from a base station to multiple user equipment, each user equipment receiving its correspondingly identified subscription-less data. The use of quantization levels and/or levels of tolerance for compensating for non-ideal differences in recipient and transmitter channel characteristics are also disclosed.

11. Serving apparatus for anonymously providing a data service to a wireless device, the serving apparatus comprising:
-
a radio transceiver; a processing device in data communication with the radio transceiver; and a computer readable apparatus comprising a medium adapted to store a computer program, the computer program which, when executed by the processing device; generates a first element based on a radio channel characteristic specific to the wireless device; associates the data service with the first element; transmits the data service and the first element via the radio transceiver; and does not identify the wireless device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A wireless apparatus for receiving a data service from a serving device, the wireless apparatus comprising:
-
a radio transceiver; a processing device in data communication with the radio transceiver; and a computer readable apparatus comprising a medium adapted to store a computer program, the computer program which, when executed by the processing device; receives a data service and a first element via the radio transceiver; generates a second element based on a radio channel characteristic specific to the serving device; compares the first and second element; and consumes the data service if the first and second element are substantially equivalent. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A method of providing data services using a wireless network, the method comprising:
-
utilizing one or more channel characteristics of a wireless channel, the wireless channel having substantially reciprocal transmission properties, to generate a unique identification for a wireless device requesting a data service; wherein the utilizing of the one or more channel characteristics does not require any information exchange between a serving device and a wireless device. - View Dependent Claims (40, 41, 42, 43, 44)

45. A mobile device, comprising:
-
a wireless transceiver capable of transmitting and receiving signals over a substantially reciprocal wireless channel; and a processor in communication with the transceiver configured to process signals received via the wireless transceiver to determine a unique signature based on one or more channel path characteristics of the substantially reciprocal wireless channel, and utilize the unique signature or an approximation thereof, as a unique identification for accessing a wireless network.
