1. A method, comprising:
- receiving signal-related information at an apparatus;
determining signal activity expected in an environment in which the apparatus is operating based on the received signal-related information;
comparing the expected signal activity to a scan schedule in the apparatus, the scan schedule comprising one or more instances during which scans are scheduled;
updating the scan schedule by altering timing for any of the one or more scan instances that potentially conflict with the expected signal activity; and
transmitting information comprising at least the updated scan schedule,wherein the signal-related information is received from, and the updated scan schedule information is transmitted to, other apparatuses in a same cognitive radio network as the apparatus, andwherein the updated scan schedule is configured to enable scanning for available bandwidth in which to operate in a television white space.

Abstract
A system for managing wireless communication in view of other potentially interfering wireless signal sources. Signal-related information may be collected from one or more apparatuses that are participating in a network. The information may then be evaluated in order to determine expected signal activity in the environment in which the apparatuses are operating. In some instances the signal activity may then be compared to a scan schedule utilized, for example, to identify legacy apparatuses operating in the environment. This scan schedule may be altered to avoid potential conflicts that may exist with the expected signal activity. The scan schedule may then be communicated to the networked apparatuses.

7. A computer program product comprising computer executable program code recorded on a non-transitory computer readable storage medium, the computer executable program code comprising:
-
code configured to cause an apparatus to receive signal-related information at an apparatus; code configured to cause an apparatus to determine signal activity expected in an environment in which the apparatus is operating based on the received signal-related information; code configured to cause an apparatus to compare the expected signal activity to a scan schedule in the apparatus, the scan schedule comprising one or more instances during which scans are scheduled; code configured to cause an apparatus to update the scan schedule by altering timing for any of the one or more scan instances that potentially conflict with the expected signal activity; and code configured to cause an apparatus to transmit information comprising at least the updated scan schedule, wherein the signal-related information is received from, and the updated scan schedule information is transmitted to, other apparatuses in a same cognitive radio network as the apparatus, and wherein the updated scan schedule is configured to enable scanning for available bandwidth in which to operate in a television white space. - View Dependent Claims (8, 9, 10, 11, 12)

13. An apparatus, comprising:
-
at least one processor; and at least one memory including executable instructions, the at least one memory and the executable instructions being configured to, in cooperation with the at least one processor, cause the apparatus to perform at least the following; receive signal-related information at the apparatus; determine signal activity expected in an environment in which the apparatus is operating based on the received signal-related information; compare the expected signal activity to a scan schedule in the apparatus, the scan schedule comprising one or more instances during which scans are scheduled; update the scan schedule by altering timing for any of the one or more scan instances that potentially conflict with the expected signal activity; and transmit information comprising at least the updated scan schedule, wherein the signal-related information is received from, and the updated scan schedule information is transmitted to, other apparatuses in a same cognitive radio network as the apparatus, and wherein the updated scan schedule is configured to enable scanning for available bandwidth in which to operate in a television white space. - View Dependent Claims (14, 15, 16, 17, 18)

19. A system, comprising:
-
an apparatus configured to operate in an environment comprising one or more other apparatuses; the apparatus further configured to receive signal-related information from the one or more other apparatuses and determine signal activity expected in the environment in which the apparatus is operating based on the received signal-related information; the apparatus further configured to compare the expected signal activity to a scan schedule in the apparatus, the scan schedule comprising one or more instances during which scans are scheduled and update the scan schedule by altering timing for any of the one or more scan instances that potentially conflict with the expected signal activity; and the apparatus further configured to transmit information comprising at least the updated scan schedule to the one or more other apparatuses, wherein the signal-related information is received from, and the updated scan schedule information is transmitted to, the one or more other apparatuses in a same cognitive radio network as the apparatus, and wherein the updated scan schedule is configured to enable scanning for available bandwidth in which to operate in a television white space.
