The Backscatter communication device 13 can be a communication device supporting a Backscatter communication technology, such as a Backscatter tag or a Backscatter reader, etc.

[0042] For ease of understanding, the related content involved in the embodiments of the present application is described as follows:

[0043] I. Backscatter communication (BSC)

[0044] Backscatter communication refers to a backscatter communication device modulating a signal to transmit its own information by using radio frequency signals of other devices or the environment. A backscatter communication terminal device (BSC UE) can be a tag in traditional radio frequency identification (RFID) or a passive Internet of Things terminal (Passive-IoT).

[0045] As a passive or low-energy technology, the backscatter technology has the technical feature of transmitting its own signal by changing the characteristics of the received environmental radio frequency signals, such as phase or amplitude information, to achieve extremely low or zero power consumption information transmission. For example, as shown in Figure 2 a backscatter transmitter transmits information to a reader by radio frequency signals emitted by the reader or radio frequency signals in the environment.

[0046] From the power supply mode, the BSC UE can be divided into three modes: passive, semi-passive, and active.

[0047] For a passive BSC UE, the BSC UE first obtains energy from external electromagnetic waves (energy harvesting) and supplies internal channel coding and modulation circuit modules to work, while communicating by reflecting and scattering radio frequency signals, thereby realizing zero-power communication.

[0048] For a semi-passive BSC UE, its internal circuit modules are powered by its own battery, and communicate by backscattering radio frequency signals. Since the internal battery is only used for simple internal circuit modules such as channel coding and modulation, the power consumption is very low, and the battery life of the BSC UE can reach more than ten years. External radio frequency signals can all be used for backscatter communication, without storing part of the energy for power supply.

[0049] For an active BSC UE, its built-in battery is not only used for simple internal circuit work such as channel coding and modulation, but also for power amplifier (PA) and low noise amplifier (LNA) circuit work, so it can realize more complex backscatter communication signal modulation and demodulation.

[0050] For example, as shown in Figure 3A Backscatter use case is shown, that is, a scenario in which a mobile phone as a Backscatter control device (Reader) is connected with smart glasses as a Backscatter terminal device (Tag), the smart glasses collect the energy of the signal transmitted by the mobile phone, and transmit the information b(t) of the Tag by reflecting the signal x(t) transmitted by the mobile phone.

[0051] II. In-device Coexistence (IDC)

[0052] The same device can simultaneously support New Radio (NR) / Long Term Evolution (LTE), and Global Navigation Satellite System (GNSS) (for example, Global Positioning System (GPS), Global Navigation Satellite System (GLONASS), BeiDou Navigation Satellite System (BDS), Galileo Satellite Navigation System (GALILEO), or Indian Constellation Navigation System (NAVIC), Wireless Local Area Network (WLAN), and Bluetooth, and the like functions.

[0053] Among them, the in-device coexistence problem can refer to the interference problem on multiple subframes or time slots in the device. At present, the NR / LTE UE has supported IDC solutions with other technologies such as GNSS, WLAN, and Bluetooth, for example, Frequency Division Multiplexing (FDM) solutions.

[0054] Optionally, the UE can report IDC assistance information according to the indication of the network, and the IDC assistance information can include the frequency point that is being affected or may be affected, and the affected system type (Victim System Type).

[0055] Wherein, the above affected system type can be used to indicate a list of affected system types of IDC interference caused by NR when configuring uplink (UL) carrier aggregation (CA). The values gps, glonass, bds, galileo and navIC represent the types of GNSS. The value WLAN represents WLAN, and the value Bluetooth represents Bluetooth.

[0056] III. UE assistance information

[0057] For the purpose of power saving or preventing overheating, the UE can send a preference indication to the network in a UE assistance information message. The network decides whether to change the configuration of the UE. For example, the UE suggests the network to configure fewer carriers, fewer multiple-input multiple-output (MIMO) layers, or discontinuous reception (DRX) preference. The network can adjust the configuration of the UE accordingly. However, the network can also not respond to the request of the UE.

[0058] For example, Figure 4 A schematic diagram of a DRX procedure is shown. Based on Figure 4 It can be known that the above DRX preference configuration can include parameters such as inactivity timer, long cycle, short cycle, short cycle timer, etc.

[0059] The information transmission method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings, some embodiments and application scenarios.

[0060] Please refer to Figure 5 , Figure 5 is a flowchart of an information transmission method provided by the embodiments of the present application, which can be executed by a terminal device, as shown in Figure 5 The method comprises the following steps:

[0061] Step 501, the terminal device sends Backscatter related information to the network side device;

[0062] Wherein, the terminal device supports a first communication technology, the network side device is a device corresponding to the first communication technology, the Backscatter related information is information related to the Backscatter communication technology, and the first communication technology is different from the Backscatter communication technology.

[0063] In this embodiment, the first communication technology can include, but is not limited to, at least one of the following: a 3GPP radio access technology (RAT), such as NR, LTE, etc.; a GNSS, such as GPS, BDS, GLONASS, GALILEO, or NAVIC, etc.; a communication technology based on an industrial scientific medical (ISM) frequency band, such as Bluetooth, WIFI, near field communication (NFC), etc.; an air interface, such as a Uu interface, a sidelink (SideLink) interface, etc.

[0064] The network side device can be a network side device corresponding to the first communication technology. For example, if the first communication technology includes a 3GPP RAT, the network side device can include a base station or a core network corresponding to the 3GPP RAT, etc.; if the first communication technology includes WIFI, the network side device can include a router corresponding to WIFI, etc.; if the first communication technology includes a GNSS, the network side device can include a system device corresponding to the GNSS, such as a GPS system, a BDS system, etc. It should be noted that, for ease of description, the first communication technology is taken as a 3GPP RAT in the following embodiments of the present application.

[0065] The Backscatter communication technology can refer to a communication technology that uses radio frequency signals in other devices or environments to modulate signals to transmit information. The Backscatter communication device, i.e., a device supporting the Backscatter communication technology, can include a first communication device for modulating signals using radio frequency signals transmitted by devices other than the first communication device or radio frequency signals in the environment to transmit information, and a second communication device for receiving radio frequency signals reflected by the first communication device to receive information. It should be noted that, in some scenarios, the first communication device can also be referred to as a Backscatter tag or a passive IoT or a Backscatter terminal, and the second communication device can also be referred to as a Backscatter reader or a Backscatter control device.

[0066] The Backscatter related information can include, but is not limited to, information related to the in-device coexistence problem between the Backscatter communication technology and the first communication technology, such as frequency domain resource information, time domain resource information, etc.

[0067] In an embodiment, the terminal device can support the first communication technology. Optionally, in this embodiment, the terminal device can report the Backscatter related information of at least one communication device supporting the Backscatter communication technology and the first communication technology, for example, the terminal device can act as a proxy of the at least one communication device supporting the Backscatter communication technology and the first communication technology, or can be an aggregation center of a plurality of communication devices supporting the Backscatter communication technology and the first communication technology, so that the at least one communication device supporting the Backscatter communication technology and the first communication technology can report the Backscatter related information to the network side device via the terminal device, so that the network side device can configure the transmission configuration information, such as frequency domain resource, time domain resource, etc., of the at least one communication device based on the reported Backscatter related information, or the network side device can control the information transmission between the at least one communication device to reduce the communication conflict or interference between the Backscatter communication technology and the first communication technology in the at least one communication device.

[0068] In another embodiment, the terminal device can support the Backscatter communication technology and the first communication technology. Optionally, in this embodiment, the terminal device can report the Backscatter related information of the terminal device to the network side device, so that the network side device can configure the transmission configuration information of the terminal device or control the information transmission between the terminal device based on the Backscatter related information of the terminal device to reduce the communication conflict or interference between the Backscatter communication technology and the first communication technology in the terminal device; or the terminal device can also report the Backscatter related information of a communication device supporting the Backscatter communication technology and the first communication technology other than the terminal device to the network side device, so that the network side device can configure the transmission configuration information of the communication device or control the information transmission between the communication device based on the reported Backscatter related information to reduce the communication conflict or interference between the Backscatter communication technology and the first communication technology in the communication device.

[0069] The information transmission method provided by the embodiments of the present application is that the terminal device sends information related to the Backscatter communication technology to the network side device corresponding to the first communication technology, so that the network side device can configure transmission configuration information related to the first communication technology or control information transmission related to the first communication technology based on the information related to the Backscatter communication technology, so as to reduce the communication conflict or interference between the Backscatter communication technology and the first communication technology, and further solve the in-device coexistence problem between the Backscatter communication technology and other communication technologies (such as NR / LTE, etc.).

[0070] Optionally, the Backscatter-related information includes at least one of the following:

[0071] IDC auxiliary information; the IDC auxiliary information includes auxiliary information related to Backscatter in-device coexistence;

[0072] Backscatter-related configuration preference information (Configuration Preference).

[0073] In an embodiment, the above-mentioned Backscatter-related information can include IDC auxiliary information. The above-mentioned IDC auxiliary information can include information related to the IDC problem between the Backscatter communication technology and the first communication technology. In actual application, the above-mentioned IDC auxiliary information can be determined according to the Backscatter communication related situation, for example, the above-mentioned IDC auxiliary information can be determined according to the frequency point, channel, etc. used by the Backscatter communication.

[0074] Optionally, the IDC auxiliary information can include but is not limited to at least one of the following:

[0075] Affected system type, the affected system type including Backscatter;

[0076] Affected frequency point, the affected frequency point including the frequency point of Backscatter data transmission and reception;

[0077] Working frequency point of Backscatter, the working frequency point including at least one of the frequency point of Backscatter energy collection and the frequency point of Backscatter data transmission and reception;

[0078] Affected channel, the affected channel including the channel used by Backscatter.

[0079] In this embodiment, the victim system type can be used to indicate the system type that the network-side device can be currently affected by the first communication technology, and when the victim system type includes Backscatter, it means that the system type that the network-side device can be currently affected by the first communication technology includes a Backscatter communication system.

[0080] The affected frequency point can also be referred to as an unusable frequency point, and the affected frequency point can include but is not limited to a frequency point for Backscatter data transmission. The working frequency point of the Backscatter can include but is not limited to at least one of a frequency point for Backscatter energy collection and a frequency point for Backscatter data transmission. The affected channel can also be referred to as an unusable channel, and the affected channel can include but is not limited to a channel used by the Backscatter. It should be noted that the affected frequency point can include a frequency point that is being affected or can be affected, and the affected channel can include a channel that is being affected or can be affected.

[0081] The following examples are used to illustrate the present embodiment:

[0082] The terminal device supports both the Backscatter communication technology and the first communication technology, and the Backscatter communication technology and the first communication technology work in parallel based on a frequency-division multiplexing (FDM) manner. In this case, the terminal device can report to the network-side device that the victim system type is Backscatter, the affected frequency point (such as a frequency point for Backscatter data transmission, or a frequency point for Backscatter data transmission and a frequency point for Backscatter energy collection), and the affected channel (such as a channel used by the Backscatter). In this way, the network-side device can configure the terminal device not to use the affected frequency point and the affected channel for transmission related to the first communication technology, for example, to use a frequency point different from the affected frequency point and a channel different from the affected channel for transmission related to the first communication technology, so as to reduce frequency conflict or radio frequency interference between the Backscatter communication technology and the first communication technology.

[0083] In another implementation, the Backscatter related information can include Backscatter related configuration preference information, to inform the network side device of configuration information of Backscatter communication preference, so that the network side device can configure the first communication technology related transmission configuration information based on the Backscatter related configuration preference information. Wherein, the Backscatter related configuration preference information can include time domain configuration related preference information.

[0084] Optionally, the Backscatter related configuration preference information can include at least one of the following:

[0085] Backscatter preference information;

[0086] Discontinuous reception (DRX) preference information;

[0087] Gap preference information;

[0088] Purpose indication information, used to indicate the purpose of configuring the Backscatter related configuration preference information.

[0089] Optionally, the Backscatter preference information can include at least one of the following:

[0090] Backscatter energy collection duration;

[0091] Backscatter data transceiving duration;

[0092] Discontinuous transmission (DTX) cycle;

[0093] DTX duration.

[0094] The Backscatter data transceiving duration mentioned above, for example, can refer to the duration of data transceiving between two energy collections.

[0095] The DRX preference information mentioned above can include, but not limited to, at least one parameter in the following: inactivity timer, long cycle, short cycle, short cycle timer, etc.

[0096] Optionally, the DRX preference information is determined based on the Backscatter preference information.

[0097] For example, the preferred DRX cycle can be determined according to the preferred Backscatter data transceiving duration, or the preferred DRX cycle is determined based on the preferred Backscatter energy harvesting duration and the Backscatter data transceiving duration.

[0098] Optionally, the DRX preference information comprises a DRX cycle, the DRX cycle covering at least a first duration and a second duration.

[0099] The first duration is a DRX On Duration corresponding to the first communication technology, and the second duration comprises a sum of a Backscatter energy harvesting duration and a Backscatter data transceiving duration, or the second duration comprises the Backscatter data transceiving duration.

[0100] In an embodiment, for example, as shown in Figure 6 the DRX cycle (DRX Cycle) covers at least the DRX On Duration corresponding to the first communication technology and the Backscatter data transceiving duration.

[0101] Taking an example that the terminal device supports the first communication technology and the Backscatter communication technology simultaneously, the Backscatter energy harvesting can be harvesting energy from radio frequency signals transmitted by a device other than the terminal device or radio frequency signals in the environment, in which case there is no communication conflict or interference between the Backscatter energy harvesting process and the first communication technology, and therefore, the Backscatter data transceiving time can be controlled to be located in a non-transmitting interval of the first communication technology, for example, a DRX off interval, that is, the DRX cycle at least comprises the DRX On Duration corresponding to the first communication technology and the Backscatter data transceiving duration, which can reduce the conflict or interference between the Backscatter data transceiving and the first communication technology.

[0102] In another embodiment, for example, as shown in Figure 7 the DRX cycle (DRX Cycle) covers at least the DRX On Duration corresponding to the first communication technology, the Backscatter data transceiving duration and the Backscatter energy harvesting duration.

[0103] For example, the terminal device supports the first communication technology and the backscatter communication technology at the same time, and the backscatter energy collection can be collecting energy by using the radio frequency signal transmitted by the terminal device. In this case, the backscatter data transceiving time and the backscatter energy collection time can be controlled to be located in the non-transmission interval of the first communication technology, for example, the DRX off interval. That is, the DRX cycle includes the DRX OnDuration corresponding to the first communication technology, the backscatter data transceiving time and the backscatter energy collection time. In this way, the conflict or interference between the backscatter data transceiving and the backscatter energy collection and the first communication technology can be reduced.

[0104] Optionally, in order to further reduce the conflict or interference between the backscatter data transceiving and the data transceiving of the first communication technology, the time length of the data transceiving of the first communication technology can be counted in advance. The DRX cycle can be greater than or equal to the sum of the DRX OnDuration corresponding to the first communication technology, the preset time length of the data transceiving of the first communication technology and the backscatter data transceiving time.

[0105] The gap preference information can include at least one of the gap cycle, the gap start time and the gap length, but is not limited to the above.

[0106] In the embodiment, the gap represented by the gap preference information is used for the backscatter communication, that is, the backscatter communication can be performed in the gap represented by the gap preference information.

[0107] Optionally, the gap preference information can be determined based on the backscatter preference information.

[0108] For example, the preferred gap length can be determined according to the preferred backscatter data transceiving time, or the preferred gap length can be determined based on the preferred backscatter energy collection time and the backscatter data transceiving time.

[0109] The purpose indication information is used to indicate the purpose of configuring the backscatter related configuration preference information. For example, the purpose indication information indicates that the purpose of configuring the backscatter configuration preference information is the backscatter communication or the low-power communication, and the communication power of the low-power communication is lower than the preset power.

[0110] The present embodiment is described below in conjunction with examples:

[0111] In a case where the terminal device supports the Backscatter communication technology and the first communication technology in a time-division multiplexing (TDM) manner, the terminal device can report to the network-side device at least one of the following Backscatter-related configuration preference information: a preferred Backscatter energy collection duration, a preferred Backscatter data transmission / reception duration, a preferred DTX configuration, a preferred DRX configuration, and a preferred Gap configuration, so that the network-side device can configure the terminal device based on the Backscatter-related configuration preference information to reduce communication conflicts or interference between the Backscatter communication technology and the first communication technology.

[0112] Optionally, the terminal device sends the Backscatter-related information to the network-side device, including:

[0113] In a case where a target condition is met, the terminal device sends the Backscatter-related information to the network-side device;

[0114] The target condition includes at least one of the following:

[0115] The terminal device is a Backscatter communication device;

[0116] IDC problems are detected between the Backscatter communication technology and the first communication technology;

[0117] The Backscatter-related information changes;

[0118] The terminal device needs to perform a service related to the first communication technology in a case where the terminal device performs Backscatter communication;

[0119] The terminal device needs to perform Backscatter communication in a case where the first communication technology is in a connected state;

[0120] The Backscatter communication technology needs to use different frequencies to transmit / receive data from the first communication technology.

[0121] In the embodiment, the terminal device as the Backscatter communication device can be understood as that the terminal device supports the Backscatter communication technology, that is, the terminal device supports the first communication technology and the Backscatter communication technology.

[0122] In an embodiment, the Backscatter related information can be sent to the network side device in the case that the terminal device supports the first communication technology and the Backscatter communication technology, or the Backscatter related information can be sent to the network side device in the case that the terminal device supports the first communication technology and the Backscatter communication technology and needs to perform the Backscatter communication.
