Abstract
The present disclosure describes an electronic device configured to concurrently transmit wake-up radio (WUR) packets in a duplicated WUR transmission mode, non-duplicated WUR transmission mode, and/or mixed WUR transmission mode in one or more channels of a wideband basic service set (BSS) communication. Receiving electronic devices may be grouped together and assigned to monitor for the WUR packets. For example, the receiving electronic devices may be assigned to a position within the one or more channels to monitor for the WUR packets.
Claims19
An electronic device comprising:
- a memory;
- and
- one or more processors communicatively coupled to the memory and configured to:
- transmit a first wake-up radio (WUR) packet in a first channel of a wideband basic service set (BSS) communication, wherein the first WUR packet comprises a first WUR beacon and an indication of a first transmission power of the first channel, wherein the first transmission power of the first channel is different than a sum transmission power of the wideband BSS communication that includes the first channel and at least one other channel;
- based on a policy, transmit the indication of the first transmission power in one out of every N WUR beacons transmitted, where N is an integer greater than 1;
- and
- transmit, substantially concurrently with the first WUR packet transmission, a second WUR packet in a duplicated WUR transmission mode in a second channel of the wideband BSS communication.
A non-transitory computer-readable medium having instructions stored therein, which when executed by one or more processors in an electronic device cause the one or more processors to perform operations for receiving a wake-up radio (WUR) packet, the operations comprising:
- receiving a first WUR packet comprising a first WUR beacon that comprises:
- an explicit mode indicator on a first channel of a wideband basic service set (BSS) communication;
- and
- an indication of a first transmission power of the first channel, wherein the first transmission power of the first channel is different than a sum transmission power of the wideband BSS communication that includes the first channel and at least one other channel, wherein based on a policy, the indication of the first transmission power is received in one out of every N WUR beacons received, where N is an integer greater than 1;
- and
- determining, based at least in part on the explicit mode indicator, a second channel of the wideband BSS communication to monitor for one or more additional WUR packets;
- receiving a second WUR packet on the second channel;
- in response to receiving the second WUR packet, waking a main radio of the electronic device;
- and
- receiving a wireless local area network (WLAN) packet using the main radio of the electronic device.
A method for an electronic device comprising:
- transmitting a first wake-up radio (WUR) packet in a first channel of a wideband basic service set (BSS) communication, wherein the first WUR packet comprises a first WUR beacon and an indication of a first transmission power of the first channel, wherein the first transmission power of the first channel is different than a sum transmission power of the wideband BSS communication that includes the first channel and at least one other channel;
- based on a policy, transmitting the indication of the first transmission power in one out of every N WUR beacons transmitted, where N is an integer greater than 1;
- and
- transmitting, substantially concurrently with the first WUR packet transmission, a second WUR packet in a non-duplicated WUR transmission mode in a second channel of the wideband BSS communication.
