Abstract
Various example embodiments provide a system for transmission of low power signals based on using transmission time as one coding parameter. A code table may be used at a transmitter and receiver to map different data to different transmission times and/or other parameters. Advantageously, large amount of information may be transmitted with short and power efficient signals, for example to report status of a sensor every now and then. A receiver may use the same code table to decode the signals. Apparatuses, methods, and computer programs are disclosed.
Claims19
An apparatus, comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer code configured to, with the at least one processor, cause the apparatus at least to:
- derive a signaling time instant from data content that is known by both the apparatus and a receiver;
- and
- transmit a signal at the signaling time instant corresponding to the data content, or determine not to transmit the signal at the signaling time instant,
- wherein the data content forces use of the signaling time instant.
A method comprising:
- deriving a signaling time instant from data content that is known by both an apparatus and a receiver;
- and
- transmitting a signal at the signaling time instant corresponding to the data content, or determining not to transmit the signal at the signaling time instant,
- wherein the data content forces use of the signaling time instant.
An apparatus, comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer code configured to, with the at least one processor, cause the apparatus at least to:
- receive a signal at a particular time that has been sent by a transmitter, or determine that the signal from the transmitter is not received at the particular time;
- compare the particular time with predetermined data associated with or stored by the apparatus and known by both the transmitter and the apparatus;
- and
- in response to receiving the signal at the particular time or determining that the signal is not received at the particular time, obtain data corresponding to the particular time from the predetermined data.
