The Backscatter communication device 13 may refer to a communication device supporting backscatter communication technology, for example, a Backscatter tag (Tag) or a Backscatter reader (Reader).

For ease of understanding, the following describes the relevant content involved in the embodiment of the present application:

1. Backscatter Communication (BSC)

Backscatter communication means that backscatter communication devices use other devices or radio frequency signals in the environment to perform signal modulation to transmit their own information. Backscatter communication terminal equipment (BSC UE) can be a tag (Tag) in traditional radio frequency identification (Radio Frequency Identification, RFID), or a passive Internet of Things terminal (Passive Internet of Things, Passive-IoT).

As a passive or low energy consumption technology, Backscatter (backscatter) technology is characterized in that it can complete the transmission of its own signal by changing the characteristics of the received environmental radio frequency signal, such as phase or amplitude information, to achieve extremely low power consumption Or information transfer with zero power consumption. For example, as shown in FIG. 2, a backscatter transmitter (Backscatter transmitter) transmits information to a reader through a radio frequency signal emitted by a reader (Reader) or a radio frequency signal in the environment.

From the perspective of energy supply, BSC UE can be divided into three types: passive, semi-passive and active.

For passive BSC UE, BSC UE first obtains energy (Energy harvesting) from external electromagnetic waves, and supplies internal channel coding and modulation circuit modules to work, and at the same time communicates by reflecting and scattering radio frequency signals, thereby realizing zero-power consumption communication .

For semi-passive BSC UE, its internal circuit module is powered by its own battery and communicates with backscattered radio frequency signals. Because its internal battery is only used for simple channel coding and modulation and other internal circuit modules, the power consumption is very low, so the battery life of BSC UE can reach more than ten years. All external radio frequency signals can be used for reverse communication without storing part of the energy for power supply.

For 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 amplification (Power Amplifier, PA) and low noise amplification (Low Noise Amplifier, LNA), etc. The circuit works, so the signal modulation and demodulation of more complex backscatter communication can be realized.

Illustratively, Figure 3 shows a Backscatter usage scenario, that is, a scenario in which a mobile phone is used as a Backscatter control device (Reader) and is connected to smart glasses as a Backscatter terminal device (Tag), and the smart glasses collect the energy of the signal sent by the mobile phone, and pass Reflect the signal x(t) sent by the mobile phone to send the Tag information b(t).

2. In-device Coexistence (IDC)

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 Navigation with Indian Constellation (NAVIC) , LAN (Wireless Local Area Network, WLAN) and Bluetooth (bluetooth) and other functions.

Wherein, the problem of coexistence in a device may refer to the problem of interference on multiple subframes or time slots in a device. Currently, NR/LTE UE already supports IDC solutions with other technologies such as GNSS, local area network, and Bluetooth, for example, Frequency Division Multiplexing (FDM) solutions.

Optionally, the UE may report IDC auxiliary information according to the instruction of the network, and the IDC auxiliary information may include frequency points that are being affected or may be affected, and an affected system type (Victim System Type).

Wherein, the aforementioned affected system types may be used to indicate a list of affected system types that NR causes IDC interference when an uplink (Up Link, UL) carrier aggregation (Carrier Aggregation, CA) is configured. The values gps, glonass, bds, galileo and navIC indicate the type of GNSS. A value of wlan indicates WLAN and a value of bluetooth indicates Bluetooth.

3. UE auxiliary information

For the purpose of saving power or preventing overheating, the UE may send a preference indication to the network in a UE assistance information message (UE assistance information). The network decides whether to change the configuration of the UE. For example, the UE suggests that the network configure fewer carriers, fewer multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO) layers, or discontinuous reception (Discontinuous Reception, DRX) preferences. The network can adjust the configuration of the UE accordingly. However, the network may not respond to the UE's request.

For example, FIG. 4 shows a schematic diagram of a DRX process. Based on FIG. 4 , it can be known that the above DRX preference configuration may include parameters such as Inactivity Timer, Long Cycle, Short Cycle, and Short Cycle Timer.
