US 2019/0357257 A1 · WIRELESS COMMUNICATION APPARATUS AND METHOD

Abstract

An electronic apparatus includes processing circuitry configured to select a first interval to be used for an access to a medium when a first condition is satisfied. The first interval has a fixed length shorter than DIFS (distribute coordination function inter frame space) defined in IEEE802.11 standard. The processing circuitry is also configured to select a second interval to be used for the access to the medium when a second condition different from the first condition is satisfied. The second interval has a fixed length equal to or longer than the DIFS defined in the IEEE802.11 standard. The electronic apparatus also includes wireless circuitry configured to access the medium to transmit a radio wave conforming to a first wireless specification different from the IEEE802.11 standard after the medium is idle for the selected first or second interval.

Dependent claims

An electronic apparatus, comprising:

processing circuitry configured to:
select a first interval to be used for an access to a medium when a first condition is satisfied, wherein the first interval has a fixed length shorter than DIFS (distribute coordination function inter frame space) defined in IEEE802.11 standard;
and
select a second interval to be used for the access to the medium when a second condition different from the first condition is satisfied, wherein the second interval has a fixed length equal to or longer than the DIFS defined in the IEEE802.11 standard;
and
wireless circuitry configured to access the medium to transmit a radio wave conforming to a first wireless specification different from the IEEE802.11 standard after the medium is idle for the selected first or second interval.
