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.
Claims20
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:
- determine a transmission time for a signal, wherein a data is encoded into the transmission time so that the transmission time corresponds to the data;
- and
- transmit the signal at the determined transmission time, or determine not to transmit the signal at the determined transmission time.
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;
- determine for the signal at least one of a reception time, a transmission time, or a time window covering the transmission time and the reception time;
- and
- decode the data based on at least one of the reception time, the transmission time, or the time window covering the transmission time and the reception time,
- wherein the data corresponds to at least one of the reception time, the transmission time, or the time window covering the transmission time and the reception time.
A system comprising:
- a transmitter configured to receive data for encoding;
- at least one processor configured to determine a transmission time for a signal, wherein data is encoded into the transmission time so that the transmission time corresponds to the data,
- wherein the transmitter is configured to transmit the signal at the determined transmission time, or determine not to transmit the signal at the determined transmission time;
- and
- a receiver also configured to receive the signal,
- wherein the at least one processor is also configured to determine for the signal at least one of a reception time, the transmission time, or a time window covering the transmission time and the reception time;
- and to decode the data based on at least one of the reception time, the transmission time or the time window covering the transmission time and the reception time, and
- wherein the data corresponds to at least one of the reception time, the transmission time, or the time window covering the transmission time and the reception time.
