Description

Devices and orchestrating system for a similar data sharing system TECHNICAL FIELD The present disclosure relates to a secondary device for use in a similar data sharing system, to an orchestrating system in the similar data sharing system and to a primary device for use with the orchestrating system. BACKGROUND Low-power networks are a crucial component of Internet-of-Things (loT) and machine-to- machine (M2M) communication. Low power devices may, for example, rely on energy-harvesting, which requires that these devices must operate in an energy efficient manner. Where devices must conserve energy, specifically those with limited resources and without a battery, needless transmission must be avoided. Such devices may be referred to as power-constrained devices. For example, 3GPP recently issued a study on ambient power-enabled loT devices, in Technical Recommendation 3GPP TR 22.840. The document discloses use cases and requirements for ambient power-enabled loT devices, being battery-less devices with limited energy storage capability (a capacitor may be included) wherein the energy is provided through the harvesting of radio waves, light, motion, heat or any other power source that could be suitable. Thus, energy is a very scarce resource in this context, and its usage is preferably optimized by limiting the number and/or size of exchanged messages. SUMMARY The inventors have realized that wireless transmissions may require a much higher energy consumption for a device than computation in that same device. Receiving data and performing computations on the received data may, therefore, be preferable over transmission of data. To that end, a secondary device is disclosed for use in a similar data sharing system comprising an orchestrating system and at least one primary device configured for transmission of first data. The secondary device is configured to receive a first radio resource indication from the orchestrating system regarding radio resources for transmission of the first data from the primary device. Such radio resource indication may specify a radio resource used for transmitting the first data by the primary device to, for example, the orchestrating system, for example, specify at least one of a time slot, frequency, code, etc. The secondary device may be configured to overhear the transmission of the first data from the primary device using the first radio resource indication. The first radio resource indication assists the secondary device to listen to the first data transmission from the primary device while the transmission is not directed to the secondary device. This includes a transmission of first data from the primary device to another device than the secondary device, for example to the orchestrating system. The transmission may also be a broadcast of the first data. In this manner, the secondary device may receive the first data from the primary device without the transmission being directed to the secondary device. The secondary device may further be configured to compare at least a part of the first data with second data accessible to the second device to obtain a comparison result. The second data may, e.g. be stored in the secondary device. The second data may have been received previously or may have been obtained locally. The comparison result shows whether or not the first data is similar to the second data which is reflected in a comparison indication. Also, the secondary device may determine the comparison indication based on the comparison result. The (value of the) comparison indication signals whether or not the secondary device may take action, for example whether the secondary device should send the second data, or a part thereof, to the recipient (e.g. the orchestrating system) of the transmission of the first data from the primary device in order for the recipient to have sufficient data available to perform its task(s). If the data is considered not similar, the comparison indication may trigger a transmission of the differences between the first and second data only. If the comparison result indicates that the received first data is similar to the second data, the comparison indication may trigger one or more actions. For example, it may be decided that nothing needs to be done. Optionally, however, the secondary device is configured to trigger a transmission so that it arrives at the recipient of the first data, such as directly to the orchestrating system, or via other devices, such as the primary device or other second device (s).. The comparison indication may, for example, trigger transmission of a small message indicating similarity of the data to the recipient, such as the orchestrating system. Another aspect of the disclosure pertains to an orchestrating system for use in a similar data sharing system comprising a plurality of devices. The orchestrating system may be configured to transmit a first radio resource indication to a set of secondary devices of
