[0183] The following embodiments of the present disclosure can be applied to the communication system shown in FIG. 1A and FIG. 1B, or part of the subject, but are not limited thereto. The subjects shown in FIG. 1A and FIG. 1B are examples, and the communication system can include all or part of the subjects in FIG. 1A and FIG. 1B, or other subjects other than those in FIG. 1A and FIG. 1B.

Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0185] Optionally, the AIOT devices can be divided into AIOT devices of type A (Device A), AIOT devices of type B (Device B), and AIOT devices of type C (Device C). Among them, the AIOT devices of type A cannot independently generate / amplify signals, for example, can use the working mode of backscatter. But it does not have the ability to amplify DL signals and / or UL signals. The AIOT devices of type B have energy storage capability, but cannot independently generate signals. For example, it can use the working mode of backscatter. And use the stored energy for DL signal and / or UL signal amplification. The AIOT devices of type A / AIOT devices of type B can use relatively simple modulation and demodulation modes, such as On-Off Keying (OOK) modulation / Phase Shift Keying (PSK) modulation, etc. The AIOT devices of type C have energy storage capability and can independently generate signals, for example, have a radio frequency (RF) module that actively transmits signals. The AIOT devices of type C can also use high-complexity modulation and demodulation modes, such as Orthogonal Frequency Division Multiplexing (OFDM) modulation and demodulation. The uplink signal or downlink signal can be amplified.

[0186] Optionally, among the above three types, the Device C has the strongest capability and the highest cost. The Device A has the weakest capability and the lowest cost. In addition, the Device A and the Device B can only use the working mode of backscatter and cannot actively transmit signals. When they need to transmit information, they need to have an external carrier wave (CW) for backscatter to support a smaller coverage range. However, the power consumption of the working mode of the Device A / Device B is much smaller than that of the working mode of the Device C.

[0187] Optionally, based on backscatter, the AIOT device needs an energy source (also can be called as CW node) to provide carrier wave (CW) for it to reflect when transmitting data. The CW is generally constant amplitude. The CW node can be a separate node or a base station / intermediate node (such as UE) in communication with the AIOT device. The AIOT device reflects the received CW, loads the signaling / data to be transmitted onto the reflected wave, and transmits the reflected wave. The reflected wave and the CW are the same frequency or have a certain frequency offset. At the same time, the CW can also charge the AIOT device. For example, the AIOT device can receive a wireless signal CW, activate the internal receiving processing module, and start working to encode and modulate the signaling / data to be uploaded by the AIOT device.

[0188] Optionally, in the AIOT application, the link and channel of the physical layer are specified (the reader can be a base station or an intermediate UE). R2D represents Reader-to-Device. D2R represents Device-to-Reader. CW2D represents carrier-wave-to-device.

[0189] Optionally, for AIOT devices that cannot actively transmit, an external carrier wave CW needs to be provided to the AIOT device for backscatter of the AIOT device. When the carrier wave CW is provided by an access network device (such as a base station) or an intermediate node terminal (such as an intermediate node UE) contained in the topology, it can be considered that the carrier wave CW is from inside the topology (CW from inside topology); when the carrier wave CW is provided by a node outside the topology, it can be considered that the carrier wave CW is from outside the topology (CW from outside topology).

[0190] Optionally, AIOT can also be called passive Internet of Things, environmental Internet of Things, etc. AIOT devices can also be called passive Internet of Things devices, environmental Internet of Things devices, etc. No limitation is made to this.

[0191] In the related art, the device for charging and / or carrying information and / or backscatter signal is not supported to be flexibly selected, thereby affecting the performance of the AIOT system.

[0208] In some embodiments, the information related to the first signal can comprise supported first signal resource information. The first information can be used to indicate the supported first signal resource information.

The first information can be used to indicate the TRP information supporting sending the first signal. That is, the first information can be used not only to support the TRP identifier of sending the first signal, but also to indicate the TRP information supporting sending the first signal. The TRP information can be, for example, the geographical location corresponding to the TRP, without limitation.

[0214] In some embodiments, the first device can request the first information fed back by the at least one second device by sending a first request to the at least one second device, and the at least one second device can feed back the first information to the first device in response to the first request.

[0215] In some embodiments, one or more of the at least one second device receiving the first request can feed back respective first information to the first device, or each of the at least one second device can feed back the first information to the first device, without limitation.

[0216] In some other embodiments, step S2101 can not be performed, and the second device can directly send the first information to the first device. For example, the first device and the second device are base stations, and the second device includes the first information in a connection establishment request message when sending the connection establishment request message to the first device.

[0217] In step S2103, the first device selects a second device from the at least one second device according to the first information.

[0218] The selected second device is used to send the first signal. For example, the selected second device can send the carrier CW. Alternatively, at least one TRP of the selected second device supporting sending the carrier CW can send the carrier CW.

[0219] In some embodiments, the number of the selected second devices can be one or more. That is, the first device can select a second device from the at least one second device with reference to the first information of the at least one second device, so that the selected second device can send the first signal.

[0221] For example, if the first information of a second device includes indication information supporting sending the first signal, the second device can be selected as the second device sending the first signal, and in addition, if the first information further includes a TRP identifier supporting sending the first signal, the TRP to which the TRP identifier supporting sending the first signal in the second device belongs can be further selected as the TRP sending the first signal. In addition, appropriate first signal resources for sending the first signal can be configured according to the supported first signal resource information, and appropriate sending power for sending the first signal can be configured according to the supported first signal sending power. Of course, the appropriate second device can also be selected based on other arbitrary possible manners referring to various possible contents in the first information, and specific individual settings can be made according to actual AIOT application requirements.

[0222] In step S2104, the first device sends a second request to the selected second device.

Thus, the first device can accurately perform AIOT related operations.

[0230] In some embodiments, if the number of selected second devices is multiple, the first device can send a second request to one or more selected second devices, or the first device can send a second request to each selected second device, without limitation.

[0232] The second information is used to configure the first signal resource. The second information can also be referred to as first signal resource configuration information, first signal configuration information, etc., without limitation. For example, the first information is CW configuration information.

[0233] In some embodiments, after the first device sends the second request to the selected second device, the selected second device can receive the second request and feed back the second information to the first device in response to the second request. When the selected second device feeds back the configured second information to the first device, the first device can timely learn the second information to determine the configuration of the first signal resource and accurately perform AIOT related operations.

[0234] In some embodiments, the second information is used to configure at least one of the following: identification of the first signal resource; bandwidth of the first signal resource; frequency domain information of the first signal; time domain information of the first signal; transmission power of the first signal. Thus, the flexibility of the first signal resource configuration can be effectively improved, and effectively applied to personalized AIOT application scenarios.

The frequency domain information of the first signal requested by the first device and the frequency domain information of the configured first signal can be the same or different. The time domain information of the first signal requested by the first device and the time domain information of the configured first signal can be the same or different. The transmission power of the first signal requested by the first device and the transmission power of the configured first signal can be the same or different. In actual configuration, the first signal resource can be configured based on AIOT application requirements.

[0236] In some embodiments, the selected second device can send the first signal based on the second information after determining the second information, and the relevant AIOT device in the AIOT application scenario can receive the first signal sent by the selected second device and implement charging, and / or carrying information, and / or backscattering based on the first signal. In addition, the first device can be the relevant AIOT device as described above, or can also be a relevant AIOT device not as described above, and no limitation is made in this regard.

[0237] In step S2106, the first device performs an AIOT-related operation according to the second information.

[0238] In some embodiments, the first device can receive the second information fed back by the selected second device, and perform an AIOT-related operation according to the second information. The AIOT-related operation can be, for example, inventory, positioning (finding), perception, command, and other services. For example, the first device can feed back the second information to a third device, which is, for example, a reader of the AIOT. The third node can be a UE, a base station, or a DU in the base station. The first device can link the second device and the third device to perform the AIOT-related operation based on the second information, and no limitation is made in this regard.

[0239] In some embodiments, the first device can configure the reader performing the AIOT operation according to the second information, so that the reader can effectively receive the feedback of the AIOT device through the instruction. The feedback of the AIOT device is the feedback of the AIOT device through the charging or reflection of the first signal.
