Abstract
In some aspects, a method of wireless communication performed by a wireless relay node includes receiving, from a first energy harvesting tag, a first data packet comprising a header and a payload, wherein one or more flag bits in the header of the first data packet indicate a level of a criticality of the payload of the first data packet; and transmitting an indication that the payload of the first data packet includes critical information based on the level of the criticality of the payload of the first data packet satisfying a criticality threshold.
Claims20
An energy harvesting tag, comprising:
- one or more memories;
- one or more antennas;
- and
- one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
- receive, via the one or more antennas, an energizing signal;
- and
- transmit, via the one or more antennas, based on energy harvested from the energizing signal, a data packet comprising a header and a payload, wherein one or more flag bits in the header indicate a level of a criticality of the payload of the data packet.
A wireless relay node, comprising:
- one or more memories;
- one or more transceivers;
- and
- one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
- receive, via the one or more transceivers, from a first energy harvesting tag, a first data packet comprising a header and a payload, wherein one or more flag bits in the header of the first data packet indicate a level of a criticality of the payload of the first data packet;
- and
- transmit, via the one or more transceivers, an indication that the payload of the first data packet includes critical information based on the level of the criticality of the payload of the first data packet satisfying a criticality threshold.
A server, comprising:
- one or more memories;
- one or more transceivers;
- and
- one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
- transmit, via the one or more transceivers, to one or more wireless relay nodes, first scheduling information indicating a first set of time slots allocated for transmission of alert packets by any wireless relay node;
- receive, via the one or more transceivers, from a wireless relay node of the one or more wireless relay nodes, over at least one time slot of the first set of time slots, an alert packet indicating that a payload of a data packet transmitted by an energy harvesting tag includes critical information;
- and
- transmit, via the one or more transceivers, to the one or more wireless relay nodes, second scheduling information indicating a second set of time slots allocated for transmission of alert packets by any wireless relay node, wherein the second set of time slots includes more time slots than the first set of time slots.
