WIRELESS-RESOURCE BROKER
First Claim
1. A method for allocating wireless resources among a plurality of users, the method comprising the steps of:
- (a) receiving one or more user parameters characterizing at least one of one or more receivers and one or more transmitters associated with one or more of the users;
(b) receiving one or more resource parameters characterizing one or more wireless resources;
(c) generating, based on the one or more user parameters and the one or more resource parameters, a policy for using one or more of the wireless resources by a particular user, wherein the policy is such that an expected utility that the particular user obtains by adopting the policy is not less than the expected utility that the particular user obtains by adopting an alternative strategy; and
(d) transmitting the policy for the particular user.

Abstract
In one embodiment, a wireless-resource broker employs a self-enforcing spectrum-sharing policy, e.g., the expected utility (e.g., rate) a user obtains by following the policy provided by the broker is not less than the expected utility that the user obtains by switching to some other strategy. Each user is associated with one or more transmitter-receiver pairs, e.g., a transmitter of a wireless device and a receiver of a base station in communication via a wireless channel. The broker receives, as input, user parameters characterizing one or more of the transmitters and/or receivers and resource parameters characterizing one or more available spectrum blocks. The broker solves a linear-programming problem to generate and transmit a recommended policy for one or more users. The policy for each user includes information such as the spectrum block(s) to which the user is assigned, the transmission power for the user, and the transmission rate for the user.

8. A wireless-resource broker for allocating wireless resources among a plurality of users, the wireless-resource broker comprising:
-
a receiver adapted to; (a) receive one or more user parameters characterizing at least one of one or more receivers and one or more transmitters associated with one or more of the users; and (b) receive one or more resource parameters characterizing one or more wireless resources; a processor adapted to generate, based on the one or more user parameters and the one or more resource parameters, a policy for using one or more of the wireless resources by a particular user, wherein the policy is such that an expected utility that the particular user obtains by adopting the policy is not less than the expected utility that the particular user obtains by adopting an alternative strategy; and a transmitter adapted to transmit the policy for the particular user. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A communications device for use with a wireless-resource broker for allocating wireless resources among a plurality of users, the communications device comprising:
-
a receiver adapted to receive, from the wireless-resource broker, a policy for using one or more of the wireless resources; and a processor adapted to selectively adopt or ignore the policy. - View Dependent Claims (16, 17, 18, 19, 20)
