Description

METHOD FOR DATA SEGMENTATION OF A DATA TRANSMISSION AND RELATED

DEVICES

The present disclosure pertains to the field of wireless communications. The present disclosure relates to a method for data segmentation of a data transmission, and related devices.

BACKGROUND

Future wireless communication services will benefit from widespread connectivity between large networks of wireless devices. Changing or recharging batteries manually may not be feasible due to the inefficiency of such battery solutions and the physical inaccessibility of some these devices.

New wireless devices, such as Ambient loT devices, are expected to be batteryless and/or to have very limited energy storage. These new wireless devices may instead be able to harvest energy directly from ambient sources such as radio waves, sun, wind, etc.

However, due to the limited energy capabilities of these wireless devices, some data transmissions performed by these wireless devices may be unable to be completed due to insufficient energy and/or charge.

SUMMARY

Accordingly, there is a need for devices and methods for data segmentation of a data transmission, which may mitigate, alleviate or address the shortcomings existing and/or may provide a data transmission segmented into two or more data blocks, thereby allowing for the wireless device to perform energy harvesting between the segmented data blocks of the data transmission. This enables the data transmission to be performed by the wireless device with an improved speed and/or efficiency.

A method for data segmentation of a data transmission is disclosed. The method is performed by a radio network node. The method comprises obtaining a device configuration comprising one or more device parameters of a wireless device including a first device parameter indicative of a data segmentation capability of the wireless device. The method comprises transmitting, to the wireless device, a data transmission configuration comprising one or more data transmission parameters indicative of data segmentation for the wireless device. The data transmission configuration is for example based on the first device parameter. A radio network node is disclosed. The radio network node comprises a memory circuitry, a processor circuitry, and a wireless interface. The radio network node is configured to perform any of the methods disclosed herein

A method for data segmentation of a data transmission is disclosed. The method is performed by a wireless device. The method comprises obtaining a data transmission configuration comprising one or more data transmission parameters. The method comprises transmitting a first data block according to the data transmission configuration. The method comprises transmitting, after a first time gap e.g., based on the data transmission configuration, a second data block according to the data transmission configuration.

A wireless device is disclosed. The wireless device comprises a memory circuitry, a processor circuitry, and a wireless interface. The wireless device is configured to perform any of the methods disclosed herein.

A method, e.g. for data segmentation of a data transmission is disclosed. The method is performed in an intermediate device. The method comprises obtaining, from a radio network node, at least a part of a data transmission configuration comprising one or more data transmission parameters. The method comprises receiving a first data block according to the data transmission configuration. The method comprises receiving, after a first time gap e.g., based on the data transmission configuration, a second data block according to the data transmission configuration.

An intermediate device is disclosed. The intermediate device comprises a memory circuitry, a processor circuitry, and a wireless interface. The intermediate device is configured to perform any of the methods disclosed herein.

It is an advantage of the present disclosure that the disclosed methods enable the wireless device to perform energy harvesting prior to the data transmission stopping due to insufficient energy. This enables a reduction in the downtime of the wireless device as energy harvesting can be performed progressively over the course of a data transmission.

It is not efficient for the wireless device to restart from the beginning whenever it run out of energy. The disclosed methods and related device provide a segmentation mechanism enabling the wireless device to segment its data transmission to two or more data blocks based on a device configuration of the wireless device, thereby enabling improved efficiency, robustness and/or speed of the data transmission performed by the wireless device. Furthermore, the disclosed methods and related devices enable an improved control of data transmission performed by the wireless device.

The disclosed methods and related devices enable longer transmissions to be provided by the wireless device in a controlled manner, such as by advantageously reducing uncontrolled delays in data transmissions caused by insufficient energy at the wireless device.

The disclosed methods and related devices may advantageously enable improved alignment and/or synchronization between the wireless device and other devices, such as nodes, of the wireless communication network e.g., enabled by trigger signals, device parameters and/or data transmission parameters.

Further, the multi-triggering disclosed herein may advantageously enable improved control of the carrier wave, thereby facilitating an improved energy harvesting efficiency at the wireless device.

Furthermore, due to the low energy nature of these wireless devices, full stack protocols may not be suitable. The disclosed methods and related devices enable a simpler protocol stack for energy harvesting to be performed, e.g., corresponding with physical and multiple access scheme layers.

Fig. 2A shows a first data transmission 16 performed by a wireless device, such as an AloT. The first data transmission 16 is performed according to the data transmission configuration.

The first data transmission 16 comprises a first data block 20, a second data block 24, a third data block 28, and a fourth data block 32, transmitted, by the wireless device, according to the data transmission configuration, e.g., as a part of the data transmission according to the data transmission configuration.

Each data block 20, 24, 28, 32 of the first data transmission 16 comprises a data block number. The data block number can be seen as a number indicative of the number of data blocks that are yet to be transmitted by the wireless device for a given data transmission, such as the first data transmission 16. For example, the radio network node may determine, based on the data block number, a quantity of data blocks of a data transmission yet to be received.

Each data block comprises a data block number, N, is for example indicative of how many data blocks remain to be transmitted by the wireless device. The first data block 20 may comprise a data block number N, where N is indicative of the total number of data blocks of a data transmission. The final data block (the fourth data block 32 in the first data transmission 16) may have a data block number of Nmin indicating that the fourth data block 32 is the final data block of the data transmission, e.g., where Nmin has a value of 0.

In first data transmission 16, as the data transmission comprises 4 data blocks, N may be 3 and Nmin may be 0. In other words, the first data block 20 comprises a first data block number 3, and the fourth data block 32 comprises a fourth data block number of 0. The second data block number of the second data block 24 is N-1 (e.g., 2), and the third data block number of the third data block 28 is N-2 (e.g., 1 ). The fourth data block number of the fourth data block 32 can be seen as N-3 (such as 0), or Nmin as it is the last data block of the first data transmission 16. The wireless device transmits, according to the data transmission configuration, the first data block 20 comprising a first preamble 21 and a first postamble 22.

According to the data transmission configuration, after a first time gap 23, the wireless device transmits a second data block 24. The second data block comprises a second preamble 25 and a second postamble 26. The wireless device performs a first energy harvesting during the first time gap 23. The energy harvested by the wireless device during the first energy harvesting is used by the wireless device to transmit the second data block 24. In other words, the first energy harvesting performed by the wireless device during the first time gap 23 enables the wireless device to have sufficient energy to transmit the second data block 24. The first time gap 23 corresponds with the first time gap disclosed in S208 of Fig. 4A, S212 of Fig. 4B, and S714 of Fig. 5.

According to the data transmission configuration, after a second time gap 27, the wireless device transmits a third data block 28. The third data block comprises a third preamble 29 and a third postamble 30. The wireless device performs a second energy harvesting during the second time gap 27. The energy harvested by the wireless device during the second energy harvesting is used by the wireless device to transmit the third data block 28. In other words, the second energy harvesting performed by the wireless device during the second time gap 27 enables the wireless device to have sufficient energy to transmit the third data block 28. The second time gap 27 corresponds with the second time gap disclosed in S213 and S214 of Fig. 4B.

According to the data transmission configuration, after a third time gap 31 , the wireless device transmits a fourth data block 32. The fourth data block comprises a fourth preamble 33 and a final postamble 34. The final postamble for example indicates the end of the first data transmission 34. The wireless device performs a third energy harvesting during the third time gap 31 . The energy harvested by the wireless device during the third energy harvesting is used by the wireless device to transmit the fourth data block 32. In other words, the third energy harvesting performed by the wireless device during the third time gap 31 enables the wireless device to have sufficient energy to transmit the fourth data block 32.

The first data transmission 16 can be seen as a data transmission having a first data segmentation type, where the data block number is arranged in a different location of the data block, such as each data block of the first data transmission 16, than for a second data segmentation type. The second data transmission 18 is a data transmission having a second data segmentation type. In the first data transmission 16, the wireless device may determine (as shown in S206B of Fig. 4A) the arrangement of the data block number in the data blocks 20,24,28,32 of the first data transmission based on a data segmentation type identifier, e.g., indicative of the first data segmentation type. For example, the data segmentation type identifier may indicate to the wireless device to transmit one or more of the data blocks 20,24,28,32 comprising the data block number in the preamble or postamble of each data block. For the first data transmission 16, the data segmentation type identifier indicates to the wireless device to include the data block number in the postamble of each data block 20,24,28,32. Accordingly, the first postamble 22, second postamble 26, third postamble 30, and the fourth postamble 34 comprise a data block number corresponding with each block. For example, the first postamble 22 comprises a first data block number of 3, the second postamble 26 comprises a second data block number of 2, the third postamble 28 comprises a third data block number of 1 , and the final postamble 34 comprises a fourth data block number of 0.

Each data block 40, 44, 48, 52 of the second data transmission 18 comprises a data block number. The data block number can be seen as a number indicative of the number of data blocks that are yet to be transmitted by the wireless device for the second data transmission 18.

The first data block 40 may comprise a data block number of N, where N is indicative of the total number of data blocks of a data transmission. The final data block (the fourth data block 52 in the second data transmission 18) may have a data block number of Nmin indicating the final data block of the data transmission, e.g., where Nmin has a value of 0.

In second data transmission 18, as the data transmission comprises 4 data blocks, N may be 3 and Nmin may be 0. In other words, the first data block 40 comprises a first data block number 3, and the fourth data block 52 comprises a fourth data block number of 0. The second data block number of the second data block 44 is N-1 (e.g., 2), and the third data block number of the third data block 48 is N-2 (e.g., 1 ). The fourth data block number of the fourth data block 52 can be seen as N-3 (such as 0), or Nmin as it is the last data block of the second data transmission 18.

The wireless device transmits, according to the data transmission configuration, the first data block 40 comprising a first preamble 41 and a first postamble 42.

According to the data transmission configuration, after a first time gap 43, the wireless device transmits a second data block 44. The second data block comprises a second preamble 45. The wireless device performs a first energy harvesting during the first time gap 43. The energy harvested by the wireless device during the first energy harvesting is used by the wireless device to transmit the second data block 44. In other words, the first energy harvesting performed by the wireless device during the first time gap 43 enables the wireless device to have sufficient energy to transmit the second data block 44. The first time gap 43 corresponds with the first time gap disclosed in S208 of Fig. 4A, S212 of Fig. 4B, and S714 of Fig. 5.

According to the data transmission configuration, after a second time gap 47, the wireless device transmits a third data block 48. The third data block 48 comprises a third preamble 49. The wireless device performs a second energy harvesting during the second time gap 47. The energy harvested by the wireless device during the second energy harvesting is used by the wireless device to transmit the third data block 48. In other words, the second energy harvesting performed by the wireless device during the second time gap 47 enables the wireless device to have sufficient energy to transmit the third data block 48. The second time gap 47 corresponds with the second time gap disclosed in S213 and S214 of Fig. 4B.

According to the data transmission configuration, after a third time gap 51 , the wireless device transmits a fourth data block 52. The fourth data block comprises a fourth preamble 33 and a final postamble 54. The final postamble 54 may for example indicate an end of the second data transmission 18. The wireless device performs a third energy harvesting during the third time gap 51 . The energy harvested by the wireless device during the third energy harvesting is used by the wireless device to transmit the fourth data block 52. In other words, the third energy harvesting performed by the wireless device during the third time gap 51 enables the wireless device to have sufficient energy to transmit the fourth data block 52.

The second data transmission 18 can be seen as a data transmission having a second data segmentation type, where the data block number is arranged in a different location of the data block, such as each data block of the second data transmission 18, than for the first data segmentation type. The second data transmission 18 is a data transmission having a second data segmentation type. In the second data transmission 18, the wireless device may determine (as shown in S206B of Fig. 4A) the arrangement of the data block number in the data blocks 40, 44, 48, 52 of the second data transmission 18 based on a data segmentation type identifier, e.g., indicative of the second data segmentation type. For the second data transmission 18, the data segmentation type identifier indicates to the wireless device to include the data block number in the preamble of each data block 40, 44, 48, 52. Accordingly, the first preamble 41 , second preamble 45, third preamble 49, and the fourth preamble 53 comprise a data block number corresponding with each block. For example, the first preamble 41 comprises a first data block number of 3, the second preamble 45 comprises a second data block number of 2, the third preamble 49 comprises a third data block number of 1 , and the fourth preamble 53 comprises a fourth data block number of 0.

Each data block, e.g., of the first data transmission 16 and/or the second data transmission 18 may have a variable size (e.g., A < A_max) where A denotes the size of a data block, and Amax denoted a maximum size of the data block. The data transmission may for example be segmented in data blocks having a fixed size during the entire transmission operation. For example, the data blocks 20, 24, 28, 32 of the first data transmission 16 and/or the data blocks 40, 44, 48, 52 of the second data transmission 18 may have the same size and/or length. In some examples, the data blocks 20, 24, 28, 32 of the first data transmission 16 and/or the data blocks 40, 44, 48, 52 of the second data transmission 18 may vary in size and/or length, e.g., the variation being determined based on the data transmission configuration.

The size can be determined, e.g., when the data blocks have a fixed size, based on the one or more of: the wireless device type, a smallest allowable energy storage device, the energy harvesting capability of the wireless device, and a corresponding energy harvesting efficiency of the wireless device.

When the data blocks have a fixed size but the amount of data to be transmitted is smaller than the available block size, the wireless device may wait until the end of the transmission of a data block to be to transmit the data block number, e.g., according to the second data segmentation type. In this period, the wireless device may perform padding by transmitting data with a given pattern, or the wireless device may not transmit anything, e.g., perform zero padding. The wireless device can use the zero padding period to harvest energy, for example when the wireless device is a backscattering device. In some examples, for data transmission according to the first data segmentation type, the wireless device may stop the data transmission when it has no data to transit as the block size number is transmitted at the beginning of the data block, such as in the preamble of the data block.

Fig. 3 shows a flow diagram of an example method 100, performed by a radio network node according to the disclosure, for data segmentation of a data transmission.

For example, the second device parameter may indicate that a maximum transmit for a data transmission may be 1000 bits.

For example, the third device parameter may be indicative of an ability of the wireless device to perform a data transmission and/or data segmentation, based on an energy availability, e.g., at a given time, such as a quantity of energy stored in the wireless device at a given time.

The method 200 for example comprises determining, based on the third device parameter indicative of an energy capability, e.g., of the wireless device, the data transmission configuration. In other words, the data transmission, such as the first data transmission 16 of Fig. 2A, can be segmented to two or more data blocks (e.g., data blocks 20, 24, 28, 32 of the first transmission 16 of Fig. 1 ) data blocks based on the amount of energy available in the energy storage of the wireless device, e.g., at a time of the data transmission.

In one or more example methods, the radio network node may for example determine (e.g., estimate), based on the third device parameter indicative of an energy capability, such as based on an energy capability of the wireless device and an amount of time available for energy harvesting, the amount of energy stored in the wireless device. For example, based on a time period of first energy harvesting and a maximum rate of energy harvesting of the wireless device, the radio network node may determine, such as estimate, an amount of energy stored in the wireless device.

In other words, the third device parameters may for example be indicative of a size of the energy storage in the device, e.g., taking into account discharging characteristics and/or an amount of energy available in the energy storage of the wireless device at a start time of the data transmission.

The fourth device parameter may for example be seen as indicative of a minimum time gap between transmission of two data blocks. The time gap can be seen as a time period during a data transmission, such as the first data transmission 16 shown in Fig. 2A, where there is a pause in the data transmission, as shown by the time gaps in Figs. 2A-2B. In other words, the time gap may be seen as a time period between two segmented data blocks where the wireless device is performing energy harvesting instead of transmitting data, e.g., as shown in Fig. 2A- 2B and S208 of Fig. 4A.

For example, the fourth device parameter may indicate to the radio network node a minimum time gap between transmission of two data blocks that the wireless device is capable of performing. In some examples, the fourth device parameter may comprise a maximum time gap, e.g., indicative of a maximum time gap that the wireless device is capable of performing.

The fifth device parameter may for example be seen as indicative of whether the wireless device requests for energy harvesting to be performed via a carrier wave. In some examples, the carrier wave may for example be seen as a wave from which wireless device is configured to harvest energy, e.g., for transmission of a subsequent data block. For example, the radio network node may determine, based on the fifth device parameter whether to transmit a request to an intermediate device to transmit a carrier wave to the wireless device, e.g., for energy harvesting. In one or more examples, the radio network node may transmit the carrier wave to the wireless device for the wireless device to perform energy harvesting using the carrier wave.

In some examples, e.g., when the wireless device is operating based on backscattering, the fifth may indicate that the wireless device requests a dedicated reference signal from the intermediate device, e.g., carrier wave emitter, for its energy harvesting to be performed by the wireless device.

The fifth device parameter may also indicate whether the wireless device requests a continuous carrier wave for energy harvesting and subsequent transmission. When fifth device parameter indicates a request for continuous carrier wave for energy harvesting and subsequent data transmission, the fifth device parameter may indicate for how long time this is requested. In some examples, the radio network node can also trigger the intermediate device to start carrier wave transmission, e.g., during the data transmission.

In some examples, the wireless device may request a continuous carrier wave for energy harvesting in preparation for subsequent transmission. In some examples, the wireless device may perform energy harvesting without a continuous carrier wave, e.g., provided by the intermediate device. When the wireless device provides a request for a continuous carrier wave for energy harvesting in preparation to subsequent data transmission, the wireless device may indicate a time period for which the continuous carrier wave is requested. The sixth device parameter can for example be seen as indicative a trigger signal request, such as a request associated with a number of trigger signals associated with a given data transmission, e.g., comprising two or more segmented blocks. For example, the sixth device parameter may comprise a trigger signal request indicative of a number of trigger signals requested by the wireless device for a given data transmission, such as data transmissions 16 and/or 18 of Figs. 2A-2B. For example, the sixth device parameter may determine, based on the sixth device parameter, a number of trigger signals to provide to the wireless device during the data transmission. In other words, the sixth device parameter can for example be seen as indicative of a request for one or more of: first trigger signal, second trigger signal, third trigger signal, etc. For example, the sixth device parameter may indicate to the radio network node to provide only one trigger signal for triggering of the data transmission, such as the first trigger signal 608, as shown in Fig. 9. When the radio network node provides one trigger signal the data transmission comprising two or more data blocks, this can be seen as the wireless device performing autonomous segmentation. In other words, autonomous segmentation can be seen as the wireless device transmitting a data block without being directly triggered by a corresponding trigger signal, as shown in Fig. 9.

For example, the sixth device parameter may indicate to the radio network node to provide one trigger signal per data block, e.g., first trigger signal 608, second trigger signal 616, third trigger signal 624, etc., as shown in Fig. 10. When the radio network node provides a trigger signal for two or more data blocks, such as for each data block as shown in Fig. 10, this can be seen as multi-triggering.

The seventh device parameter may for example be indicative of an identity of the wireless device. For example, the seventh device parameter may be indicative of a type of wireless device, e.g., where the wireless device type is associated with the device parameters of the wireless device. For example, one or more of: compatible energy sources for energy harvesting by the wireless device, maximum and/or minimum rate of energy harvesting, and maximum and/or minimum energy storage capability of the wireless device may be common across one or more wireless devices of the same type. In some examples, the seventh device parameter comprises a unique identifier, e.g., wireless device identifier, corresponding with a given wireless device.

In some examples, a database, such as an external server device, may comprise one or more device parameters that correspond with a given wireless device, and/or wireless device type. In one or more example methods, the radio network node may obtain, based on the seventh device parameter, such as based on the identifier, one or more device parameters corresponding with the wireless device from the database, such as the external server device. For example, obtaining S102 the device configuration may comprise obtaining, from the wireless device, e.g., via the intermediate device, only the seventh parameter, e.g., an identifier of the wireless device, and then obtaining one or more device parameters corresponding with the seventh device parameter from a database. This may advantageously enable the wireless device to reduce the amount of transmitted data, thereby reducing the energy usage of the wireless device, resulting in a reduction in the number of time gaps for data harvesting during the data transmission, and thereby enabling faster and/or more efficient transmission by the wireless device of the data transmission.

In one or more example methods, obtaining S102 the device configuration comprises determining one or more device parameters of the wireless device, e.g., indicative of a segmentation capability of the wireless device.

The method 100 comprises transmitting S106, to the wireless device, a data transmission configuration comprising one or more data transmission parameters indicative of data segmentation for the wireless device. The data transmission configuration is based on the first device parameter.

In some examples, transmitting S106, to the wireless device, the data transmission configuration comprises transmitting, via the intermediate device, the data transmission to the wireless device.

The data transmission configuration may be seen as a configuration for a data transmission, e.g., a data transmission performed by the wireless device. For example, the wireless device may be configured, based on the data transmission configuration provided by the radio network node, e.g., based one or more data transmission parameters, to perform the data segmentation of the data transmission. In other words, the wireless device may be configured to perform the data segmentation of the data transmission according to the data transmission configuration, e.g., according to one or more data transmission parameters.

The data transmission configuration may be indicative of one or more transmission settings for the wireless device, e.g., transmission settings based on which the wireless device device may perform the data transmission and/or data segmentation of the data transmission. In other words, the data transmission configuration can for example be seen as data segmentation settings.

The wireless device may for example perform the data segmentation according to the data transmission configuration for one or more subsequent data transmissions. The data transmission configuration can for example be seen as a static or semi-static configuration. In other words, the method 100 may for example comprise providing, to the wireless device, an updated data transmission configuration, e.g., updated based on one or more previous data transmissions and/or previous data segmentations. In some examples, the method comprises updating, e.g., based on one or more previous data transmissions, the data transmission configuration.

In one or more example methods, transmitting S106, to the wireless device, the data transmission configuration, comprises transmitting to the wireless device, a data transmission configuration per data transmission, thereby enabling improved flexibility of the data transmission.

The one or more data transmission parameters can for example be seen as one or more data transmission parameters, based upon which the wireless device may segment the data transmission, e.g., into two or more data blocks.

In one or more example methods, the one or more data transmission parameters comprise one or more of: a first data transmission parameter indicative of a minimum time gap between two data blocks, a second data transmission parameter indicative of a maximum data block size, a third data transmission parameter indicative of a maximum occupation time, a fourth data transmission parameter indicative of a maximum number of data blocks, a fifth data transmission parameter indicative of a back-off period, and a data segmentation type identifier indicative of an arrangement of a data block number in a data block.

For example, the wireless device may transmit the data transmission according one or more of the one or more data transmission parameters.

The first data transmission parameter for example indicates a minimum time gap, such as minimum time period, between two segmented time blocks to be transmitted by the wireless device. For example, the first data transmission parameter may indicate a minimum time gap, e.g., time gap in the data transmission, such as time gap between two segmented blocks of the data transmission, that would enable the wireless device to harvest sufficient energy to transmit the second data. For example, the first data transmission parameter may indicate to the wireless device a minimum first time gap, such as an estimated minimum first time gap, after transmission of a first data block that would enable the wireless device to harvest sufficient energy to transmit the second data block. In some examples, the first data transmission parameter may comprise a maximum time gap, e.g., indicative of a maximum time gap for energy harvesting. The second data transmission parameter is for example indicative of a maximum block length, such as size, of a data block of the data transmission. The second data transmission parameter may for example comprise information indicative of a fixed block size and/or fixed block length for one or more, such as each, of the data blocks of the data transmission. The second data transmission parameter may for example comprise information indicative of one or more varied block sizes and/or varied block lengths for one or more, such as each, of the data blocks of the data transmission. In other words, the second data transmission parameter may for example indicate that the data block size and/or length may be fixed or variable for the entire data transmission.

The third data transmission parameter is for example indicative of a maximum number and/or proportion of resources of the wireless device that may be occupied for a given time period, e.g., during the data transmission. In some examples, the third data transmission parameter may be indicative of an occupation time for which one or more resources of the wireless device may be occupied, such as used for the data transmission. The resources of the wireless device can for example comprise the transmitting elements, receiving elements and/or data harvesting elements, etc. In some examples, the number of resources that can be occupied over a certain time, as denoted by T_on, may for example be limited to -_r < a where T_totai is the total time T total period needed for entire data transmission, and a is for example the third data transmission parameter.

The fourth data transmission parameter is for example indicative of a maximum number of data blocks for a given data transmission. For example, the fourth data transmission parameter can be seen as indicative of a maximum number of segmentations, e.g., for provision of data blocks, that can be performed by the wireless device for a given data transmission. For example, in Figs. 2A-2B the radio network node transmitted to the wireless device a fourth data transmission parameter indicating that for example that 4 is the maximum number of data blocks for the first data transmission 16 and the second data transmission 18. In some examples, the fourth data transmission parameter is indicative of a maximum number of data blocks that the radio network node supports, such as a data block capacity, such as capability, of the radio network node. The maximum, such as total, number of data blocks can be based on the total available data in the wireless device. The data transmission, such as the uplink data transmission, may for example be scheduled until it reaches this data block capacity of the radio network node and/or when device indicates when the wireless device indicates to the radio network node that there is no more data to transmit. When the number of data blocks becomes larger than the data block capacity of the radio network node, the wireless device may be configured to start a new data transmission, e.g., comprising one or more data blocks. The fifth data transmission parameter may indicate, e.g., to the wireless device, a back-off period. In one or more example methods, the fifth data transmission parameter comprises an arbitrary, e.g., randomly determined within a given range, back-off value indicative of a back-off period. In one or more example methods, the fifth data transmission parameter may be indicative of a starting time window and/or the back-off time window. The starting time window can for example be seen as the time window for starting the transmission of one or more data blocks of the data transmission. The back-off period may for example be seen as a time period where the data transmission is further paused and/or allowing further energy harvesting, e.g., to enable one or more resources of the wireless device to be applied for other data transmissions. The fifth data transmission may for example enable a reduction, such as a minimization, of the interference of other wireless devices, e.g., user equipment, with the data transmission of the wireless device.

The data segmentation type identifier is for example indicative of data segmentation type associated with a given data transmission. For example, the data segmentation type identifier may be indicative of whether the wireless device is to perform a first type of data segmentation, e.g., as shown in Fig. 2A, or a second type of data segmentation, e.g., as shown in Fig. 2B. For example, the data segmentation type identifier may be indicative of location of a data block number in a data block. For example, the data segmentation type identifier may be indicative of whether the data block number is to be located in the preamble of the data block of a data transmission (e.g., as in Fig. 2A) and/or in the postamble of a data block of a data transmission (e.g., as shown in Fig. 2B).

The device may in some examples autonomously perform segmentation, as shown in Fig. 9. The device may for example indicate, such as request, for data segmentation based on for instance buffer status. For example, when the buffer status indicates a high level of buffering, the wireless device may request data segmentation. For example, the data transmission configuration may comprise information indicative of buffering associated with the data transmission. In some examples, the data transmission configuration may indicate the data rate of the transmission and/or the active power consumption, e.g., of the wireless device, during the transmission.

The wireless device may for example indicate request a new trigger for each new block it will transmit, or it may indicate that a single trigger is sufficient and/or that the wireless device can autonomously transmit subsequent data without any additional triggers, such as without any additional triggers beyond the first trigger signal. In some examples, when the device requests a new trigger, a binary value, such as a one-bit flag, indicative of a request for multi-triggering may be provided to the intermediate device and/or the radio network node. For example, the sixth device parameter may comprise a binary value indicating whether the wireless device requests multi-triggering.

In the case of multi-trigger not being requested, the wireless device may indicate, e.g., in the first data block, how many data blocks it is planning to transmit in the data transmission. The trigger signal provided to the wireless device may for example comprise information indicative of when the wireless device is allowed to transmit. The wireless device for example be allowed to transit, e.g., by the radio network node and/or the intermediate device, during a certain time duration and/or during that time duration in specific occasions.

The use of the terms “first”, “second”, “third” and “fourth”, “primary”, “secondary”, “tertiary” etc. does not imply any particular order, but are included to identify individual elements. Moreover, the use of the terms “first”, “second”, “third” and “fourth”, “primary”, “secondary”, “tertiary” etc. does not denote any order or importance, but rather the terms “first”, “second”, “third” and “fourth”, “primary”, “secondary”, “tertiary” etc. are used to distinguish one element from another. Note that the words “first”, “second”, “third” and “fourth”, “primary”, “secondary”, “tertiary” etc. are used here and elsewhere for labelling purposes only and are not intended to denote any specific spatial or temporal ordering. Furthermore, the labelling of a first element does not imply the presence of a second element and vice versa.

It may be appreciated that the figures comprise some circuitries or operations which are illustrated with a solid line and some circuitries, components, features, or operations which are illustrated with a dashed line. Circuitries or operations which are comprised in a solid line are circuitries, components, features or operations which are comprised in the broadest example. Circuitries, components, features, or operations which are comprised in a dashed line are examples which may be comprised in, or a part of, or are further circuitries, components, features, or operations which may be taken in addition to circuitries, components, features, or operations of the solid line examples. It should be appreciated that these operations need not be performed in order presented. Furthermore, it should be appreciated that not all of the operations need to be performed. The example operations may be performed in any order and in any combination. It should be appreciated that these operations need not be performed in order presented. Circuitries, components, features, or operations which are comprised in a dashed line may be considered optional.

Other operations that are not described herein can be incorporated in the example operations. For example, one or more additional operations can be performed before, after, simultaneously, or between any of the described operations.

Certain features discussed above as separate implementations can also be implemented in combination as a single implementation. Conversely, features described as a single implementation can also be implemented in multiple implementations separately or in any suitable sub-combination. Moreover, although features may be described above as acting in certain combinations, one or more features from a claimed combination can, in some cases, be excised from the combination, and the combination may be claimed as any sub-combination or variation of any sub-combination

It is to be noted that the word "comprising" does not necessarily exclude the presence of other elements or steps than those listed.

It is to be noted that the words "a" or "an" preceding an element do not exclude the presence of a plurality of such elements.

It is to be noted that the term "indicative of" may be seen as “associated with”, “related to”, “descriptive of”, “characterizing”, and/or “defining”. The terms “indicative of”, “associated with”, “related to”, “descriptive of”, “characterizing”, and “defining” can be used interchangeably. The term “indicative of” can be seen as indicating a relation. For example, weight data indicative of weight may comprise one or more weight parameters.

It is to be noted that the word "based on" may be seen as “as a function of” and/or “derived from”. The terms “based on” and “as a function of” can be used interchangeably. For example, a parameter determined “based on” a data set can be seen as a parameter determined “as a function of” the data set. In other words, the parameter may be an output of one or more functions with the data set as an input.

A function may be characterizing a relation between an input and an output, such as mathematical relation, a database relation, a hardware relation, logical relation, and/or other suitable relations.

It should further be noted that any reference signs do not limit the scope of the claims, that the examples may be implemented at least in part by means of both hardware and software, and that several "means", "units" or "devices" may be represented by the same item of hardware.

Language of degree used herein, such as the terms “approximately,” “about,” “generally,” and “substantially” as used herein represent a value, amount, or characteristic close to the stated value, amount, or characteristic that still performs a desired function or achieves a desired result. For example, the terms “approximately”, “about”, “generally,” and “substantially” may refer to an amount that is within less than or equal to 10% of, within less than or equal to 5% of, within less than or equal to 1 % of, within less than or equal to 0.1% of, and within less than or equal to 0.01% of the stated amount. If the stated amount is 0 (e.g., none, having no), the above recited ranges can be specific ranges, and not within a particular % of the value. For example, within less than or equal to 10 wt./vol. % of, within less than or equal to 5 wt./vol. % of, within less than or equal to 1 wt./vol. % of, within less than or equal to 0.1 wt./vol. % of, and within less than or equal to 0.01 wt./vol. % of the stated amount.

The various example methods, devices, nodes and systems described herein are described in the general context of method steps or processes, which may be implemented in one aspect by a computer program product, embodied in a computer-readable medium, including computerexecutable instructions, such as program code, executed by computers in networked environments. A computer-readable medium may include removable and non-removable storage devices including, but not limited to, Read Only Memory (ROM), Random Access Memory (RAM), compact discs (CDs), digital versatile discs (DVD), etc. Generally, program circuitries may include routines, programs, objects, components, data structures, etc. that perform specified tasks or implement specific abstract data types. Computer-executable instructions, associated data structures, and program circuitries represent examples of program code for executing steps of the methods disclosed herein. The particular sequence of such executable instructions or associated data structures represents examples of corresponding acts for implementing the functions described in such steps or processes.
