Abstract
A radio device for a wireless communication network includes a backscatter transmitter for transmitting a signal using a backscattered signal, and to at least one or more groups of a plurality of different device groups.
Claims28
A radio device for a wireless communication network, comprising
- a backscatter transmitter for transmitting a signal using a backscattered signal,
- wherein the radio device belongs to at least one or more groups of a plurality of different device groups,
- wherein the radio device is to receive an incident signal which indicates at least one group of the plurality of different device groups, and
- wherein the radio device is to determine whether or not the at least one group indicated by the incident signal matches one or more or all of the groups to which the radio device belongs to, wherein
- if there is a match, the radio device transmits a signal using the backscattered signal, and/or
- if there is no match, the radio device does not transmit a signal using the backscattered signal.
3 more elements
A reader device for a wireless communication network, comprising
- a transmitter for transmitting a signal to one or more radio devices of the wireless communication network, the radio devices using a backscattered signal for a communication within the wireless communication network and wherein belonging to at least one or more groups of a plurality of different device groups,
- wherein the reader device is to transmit a signal which indicates at least one of the plurality of different device groups for allowing a radio device is to determine whether or not the at least one group indicated by the signal matches one or more or all of the groups to which the radio device belongs to, wherein
- if there is a match, the radio device transmits a signal using the backscattered signal, and/or
- if there is no match, the radio device does not transmit a signal using the backscattered signal.
1 more element
A method for operating a radio device for a wireless communication network, the method comprising
- transmitting a signal using a backscattered signal,
- wherein the radio device belongs to at least one or more groups of a plurality of different device groups,
- wherein the radio device receives an incident signal which indicates at least one group of the plurality of different device groups, and
- wherein the radio device determines whether or not the at least one group indicated by the incident signal matches one or more or all of the groups to which the radio device belongs to, wherein
- if there is a match, the radio device transmits a signal using the backscattered signal, and/or
- if there is no match, the radio device does not transmit a signal using the backscattered signal.
