Abstract
The present disclosure provides a communication apparatus that comprises a receiver which, in operation, receives a wake-up radio (WUR) frame, during an on duration in a duty cycle, in a first channel assigned to the communication apparatus by an Access Point (AP), and receives a WUR Beacon frame in a second channel, a transmission of the WUR Beacon frame being scheduled at a target WUR beacon transmission time (TWBTT); and a processor which, in operation, operates the duty cycle, wherein, during a determined time from the TWBTT, any WUR frame is not transmitted in the first channel from the AP.
Claims20
A communication apparatus comprising:
- a receiver which, in operation, receives a wake-up radio (WUR) frame, during an on duration in a duty cycle, in a first channel assigned to the communication apparatus by an Access Point (AP), and receives a WUR Beacon frame in a second channel, a transmission of the WUR Beacon frame being scheduled at a target WUR beacon transmission time (TWBTT);
- and
- a processor which, in operation, operates the duty cycle, wherein:
- during a determined time from the TWBTT, any WUR frame is not transmitted in the first channel from the AP, and
- the determined time varies depending on whether the first channel and the second channel are on the same or different frequency bands.
