Abstract
Interference management in a wireless network is disclosed in this document. Two networks with overlapping frequency bands and coverage areas are configured to cooperate in order to mitigate mutual interference. Some embodiments relate to medium reservation in a first network to protect a transmission in a second network, while other embodiments relate to aligning communication parameters between the networks.
Claims22
A method, comprising:
- detecting, in a network apparatus, presence of a first network and a second network on overlapping frequency bands;
- determining a first operating bandwidth of the first network, where the first operating bandwidth comprises a first upper frequency and a different first lower frequency;
- determining a second operating bandwidth of the second network, where the second operating bandwidth comprises a second upper frequency and a different second lower frequency;
- detecting that the first operating bandwidth and the second operating bandwidth are at least partially different, where the detecting comprises determining that at least one of the first upper frequency is different from the second upper frequency or the first lower frequency is different from the second lower frequency;
- in response to detecting that the first operating bandwidth and the second operating bandwidth are at least partially different, causing at least a first access point of the first network to initiate a procedure to change at least one operating bandwidth of a set comprising the first operating bandwidth and the second operating bandwidth so that the operating bandwidths of the first network and the second network are the same after the change.

An apparatus comprising:
- at least one processor;
- and
- at least one non-transitory memory including a computer program code,
- wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- detect presence of a first network and a second network on overlapping frequency bands;
- determine a first operating bandwidth of the first network, where the first operating bandwidth comprises a first upper frequency and a different first lower frequency;
- determine a second operating bandwidth of the second network, where the second operating bandwidth comprises a second upper frequency and a different second lower frequency;
- detect that the first operating bandwidth and the second operating bandwidth are at least partially different, where the detecting comprises determining that at least one of the first upper frequency is different from the second upper frequency or the first lower frequency is different from the second lower frequency;
- in response to the detection that the first operating bandwidth and the second operating bandwidth are at least partially different, cause at least a first access point of the first network to initiate a procedure to change at least one operating bandwidth of a set comprising the first operating bandwidth and the second operating bandwidth so that the operating bandwidths of the first network and the second network are the same after the change.

A non-transitory program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for performing operations, the operations comprising:
- detecting presence of a first network and a second network on overlapping frequency bands;
- determining a first operating bandwidth of the first network, where the first operating bandwidth comprises a first upper frequency and a different first lower frequency;
- determining a second operating bandwidth of the second network, where the second operating bandwidth comprises a second upper frequency and a different second lower frequency;
- determining that the first operating bandwidth and the second operating bandwidth are at least partially different, where the determining that the first operating bandwidth and the second operating bandwidth are at least partially different comprises at least one of determining that the first upper frequency is different from the second upper frequency or determining that the first lower frequency is different from the second lower frequency;
- in response to the determining that the first operating bandwidth and the second operating bandwidth are at least partially different, causing at least a first access point of the first network to initiate a procedure to change at least one operating bandwidth of a set comprising the first operating bandwidth and the second operating bandwidth so that the operating bandwidths of the first network and the second network are the same after the change.
