[0127] As shown in Figure 1A, a communication system 100 includes a terminal 101 and a network device 102. The network device 102 may include an access network device and / or a core network device.

[0128] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0132] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0133] In some embodiments, the core network device may be a single device including a first network element, or may be a plurality of devices or a group of devices, each including a first network element. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0135] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1A are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include entities other than those shown in Figure 1A.

Furthermore, multiple systems may be combined (for example, LTE and NR).

[0137] In some cases, IoT devices are often powered by traditional batteries with limited lifespans, negatively impacting the user experience. The expected astronomical growth in the number of IoT devices, coupled with the massive scale of these devices, has pushed maintenance expenses, including labor and battery costs, to a whole new level. Billions of traditional batteries are discarded each year, with only a small fraction effectively recycled, negatively impacting the Earth's ecosystem. Maintaining IoT network operations and replacing batteries can be extremely challenging in extreme environmental conditions. Battery-free IoT communications have been proposed to improve network performance and sustainability, expanding their application scenarios. Furthermore, battery-free communications are more environmentally friendly and safer for children and the elderly. Eliminating traditional batteries significantly reduces device size and cost, paving the way for a variety of new applications.

[0138] In some implementations, various Low Power Wide Area (LPWA) technologies, such as Machine Type Communication (MTC), Narrow Band Internet of Things (NB-IoT), and Reduced Capability (RedCap), have been developed to meet the growing demands of various vertical sectors. These LPWA technologies offer low cost, low power consumption, and large-scale connectivity, meeting the requirements of many applications. However, many use cases and applications remain unaddressed. First, battery-powered devices are not suitable, such as in extreme environmental conditions (e.g., high voltage, extremely high / low temperatures, and humid environments). Second, maintenance-free devices are required (e.g., devices without traditional batteries requiring replacement). Finally, ultra-low complexity, very small device size / form factor (e.g., mm thickness), and extended lifecycles are required. Ambient-powered IoT devices are promising technologies that can address these unmet needs. Ambient-powered IoT devices are IoT devices powered by energy harvesting, either without batteries or with limited energy storage capabilities (e.g., using capacitors). Energy is collected from radio waves, light, motion, heat, or any other suitable power source.

[0139] Energy obtained from the environment can drive data transmission and wireless communication of sensing nodes. The current mainstream low-power IoT communication chips (such as BLE, LoRa, NB-IoT) have a transmit and receive power consumption of tens or even hundreds of milliwatts, while the energy obtained by environmental energy harvesting is only at the microwatt level, which is unable to drive these types of nodes to work. Therefore, a new wireless communication technology is needed to reduce communication energy consumption to tens of microwatts or even less than ten microwatts. The current mainstream method uses backscatter communication technology. Backscatter Communications is one of the key technologies for building a green, energy-saving, low-cost, and flexibly deployable future Internet of Things, and is an important means to achieve "Intelligent Connection of Everything". The methods that can be used include backscatter transmission (Backscatter Communications) technology.

[0140] As shown in Figure 1B, backscatter transmission can utilize the principle of RF signal backscattering to design extremely low-power modulation and transmission technologies. A reader sends a physical layer signal to an ambient IoT device. This physical layer signal can be a pulse signal or other AC signal. In some embodiments, this physical layer signal is used to provide energy for the ambient IoT device to transmit the signal. Therefore, this physical layer signal can be referred to as an excitation signal or trigger signal. For example, since a portion of the excitation signal is reflected when it reaches the ambient IoT device, the ambient IoT device can adjust the matching between the receiving antenna and the impedance according to the intended information to enhance the reflection of the incident excitation signal and modulate the acquired sensor data onto the reflected signal to complete the data transmission. This process is similar to a reflector. Compared to other communication technologies, backscatter transmission does not require complex RF structures, reducing the use of components such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also does not require complex baseband processing. Therefore, it can simplify the design of ambient IoT devices and significantly reduce the cost of ambient IoT device nodes. Ambient IoT devices are IoT devices that use environmental energy to operate. This environmental energy can include the aforementioned wireless signal energy, as well as other environmental capabilities such as geothermal energy and / or light energy.

[0141] Here, the device that sends a physical layer signal to the ambient IoT device and triggers the ambient IoT device to return a reflected signal can be called an anchor point of the ambient IoT device reader.

[0142] It is worth noting that an ambient IoT device is a device that uses the backscatter transmission mechanism for wireless communication. In specific implementations, other devices can also use the backscatter transmission mechanism for wireless communication.

[0143] The anchor point or reader of the ambient IoT device may be a network node of a wireless communication network, such as an access network device, a relay node (or intermediate node), or a terminal.

[0144] Backscatter transmission network architectures can include but are not limited to the following:

[0145] Architecture 1: As shown in Figure 1C, uplink (UL) and downlink (DL) data transmission is performed directly between ambient IoT devices and access network devices.

[0146] Architecture 2: As shown in Figure 1D, DL and UL data transmission occurs indirectly between ambient IoT devices and access network equipment. Intermediary nodes (also called auxiliary nodes) are present to forward data. These nodes can be relays, integrated access backhaul (IAB), user equipment (UE), or repeaters (RP).

[0147] Architecture 3: As shown in Figure 1E, data is directly transmitted between the ambient IoT device and the access network device on the uplink (UL), and an auxiliary node exists on the downlink (DL) to assist the base station and the ambient IoT device in downlink transmission. As shown in Figure 1F, data is directly transmitted between the ambient IoT device and the access network device on the DL, and an auxiliary node exists on the UL to assist the base station and the ambient IoT device in uplink transmission. Exemplarily, the auxiliary node can be a relay, an integrated access backhaul (IAB) node, a first terminal, and a network controlled repeater (NCR).

[0148] Architecture 4: As shown in Figure 1G, ambient IoT devices and UEs directly receive and transmit data on the downlink and uplink. The UE collects data and forwards it to the network.

[0149] As shown in Figure 1H, ambient IoT devices that use the backscatter transmission mechanism for wireless communication can be divided into the following three types:

[0150] Device A: has no energy storage, cannot generate or amplify signals independently, and can only perform backscatter transmission.

[0151] Device B: Has energy storage, cannot generate signals independently, and can only perform backscatter transmission. The use of stored energy can include amplification of the backscattered signal.

[0152] Device C: has energy storage and can independently generate signals, that is, has an active radio frequency (RF) component for transmission. In view of this, as shown in Figure 2A, an embodiment of the present disclosure provides a resource configuration method performed by a communication system. The method may include:

[0153] S2101: The first terminal sends a message to the network device.

[0154] In some embodiments, the first terminal may provide an excitation signal to the second terminal, and / or receive information sent by the BS from the second terminal.

The first terminal can serve as an intermediate node as shown in FIG1D . Alternatively, the first terminal can serve as an auxiliary node as shown in FIG1E and / or FIG1F . The first terminal can also be a terminal as shown in FIG1G .

[0158] In some embodiments, the first message may be used by the first terminal to request the first resource from the network device.

[0159] In some embodiments, the first message is used to request a semi-statically configured first resource.

[0160] In some embodiments, the first resource may be a periodic resource or a semi-static resource.

[0161] If the first resource is a semi-static resource, the first message may be used to request semi-static configuration information.

[0162] In some embodiments, the first message may be used to request a first resource dynamically configured by a network device, where the first resource is used for the first terminal to send a CW to the second terminal and / or receive a CW from the second terminal.

[0163] In some embodiments, the fifth message includes resource information of a second resource, where the second resource is used by the network device to configure the first resource for the first terminal.

[0164] In some embodiments, the first message and the fifth message may be different messages.

If the first message and the fifth message are the same message, the message includes a configuration request for requesting configuration of the first resource and may also include resource information for configuring the second resource.

[0166] In some embodiments, the first terminal sends a radio resource control (RRC) message, a media access control (MAC) layer message, or uplink control information (UCI) to the network device.

[0179] If the first terminal acts as an intermediate node as shown in Figure 1D, it will perform CW transmission and BS reception. The CW transmission can be used to provide an excitation signal to the ambient energy IoT device. The BS reception can be the wireless signal returned by the ambient energy IoT device based on the CW transmission.

[0180] If the first terminal acts as an auxiliary node as shown in FIG1E , the first terminal will perform CW transmission. This CW transmission can be used to provide an excitation signal to the ambient energy IoT device. The BS transmission of the ambient energy IoT device is directly returned to the access network device.

[0181] If the first terminal acts as an auxiliary node as shown in FIG1F , the first terminal will perform BS transmission. In this case, the CW transmission of the environmental IoT device can be performed by the access network device.

[0182] If the first terminal is as shown in FIG. 1G , the first terminal will perform CW transmission and BS reception.

[0183] In some embodiments, UL transmission may be a signal transmitted by the terminal to the access network device on the uplink.

[0184] In some embodiments, DL reception may be a terminal receiving a signal sent by an access network device in a downlink.

[0185] In some embodiments, both UL transmission and DL reception occur at the Uu port of the first terminal, and the UL transmission and DL reception may be collectively referred to as Uu port transmission.

[0186] S2102: The network device sends configuration information to the first terminal.

[0187] In some embodiments, the configuration information is used at least to configure the first resource.

[0188] In some embodiments, the first resource is used for continuous wave (CW) transmission and / or backscatter BS reception at the first terminal.

[0189] In some embodiments, the CW transmission is used to provide an excitation signal to the second terminal.

[0190] For example, the first resource is used for CW transmission of the first terminal. Alternatively, the first resource is used for BS reception of the first terminal. Alternatively, the first resource is used for CW transmission and BS reception of the first terminal.

[0191] In some embodiments, the excitation signal may be used to provide energy to the second terminal.

[0192] In some embodiments, the network device sends an RRC message, a MAC layer message, or downlink control information (DCI) carrying configuration information.

[0193] The first resource is used for CW transmission and / or BS reception, and the first terminal does not perform uplink UL transmission and / or does not perform downlink DL reception on at least the first resource.

[0195] In some embodiments, the first resource is used for CW transmission and / or BS reception, and the first terminal does not perform UL transmission and does not perform DL reception on the first resource and in the first interval.

[0196] The first interval is used for frequency domain isolation of CW transmission from at least one of UL transmission and DL reception; and / or the first interval is used for time domain isolation of BS reception from at least one of UL transmission and DL reception.

[0197] In some embodiments, the first interval is used for frequency domain protection (or for frequency domain isolation).

[0198] In some embodiments, the first interval is used for time domain protection (or for time domain isolation).

[0199] In some embodiments, the first interval is used for protection of the frequency domain and the time domain (or for isolation of the frequency domain and the time domain).

[0200] If the first interval is used for time domain isolation or frequency domain isolation, good isolation protection can be achieved, and the resources required for isolation can be reduced, thereby improving the effective use of resources.

[0201] If the first interval is used for time domain isolation and frequency domain isolation, this can effectively achieve isolation between different transmissions, reduce interference within the first terminal, protect the hardware of the first terminal, and provide sufficient conversion time for changing the transmission type of the first terminal to ensure the communication quality of various transmissions.

[0202] In some embodiments, the first resource is dedicated to CW transmission, and the first terminal does not perform UL transmission, DL reception, or BS reception on the first resource.

[0203] If the first resource is dedicated to CW transmission, the first resource is not used for UL transmission, DL reception, and BS reception, which can maximize the CW transmission without interference.

[0204] In some embodiments, the first resource is dedicated to CW transmission, and the first terminal does not perform UL transmission, does not perform DL reception, and does not perform BS reception on the first resource and within the second interval; the second interval is used for frequency domain isolation of CW transmission and at least one of UL transmission, DL reception, and BS reception; and / or, the second interval is used for time domain isolation of BS reception and at least one of UL transmission, DL reception, and BS reception.

[0205] In some embodiments, the second interval is used for frequency domain protection (or for frequency domain isolation).

[0206] In some embodiments, the second interval is used for time domain protection (or for time domain isolation).

[0207] In some embodiments, the second interval is used for protection of the frequency domain and the time domain (or for isolation of the frequency domain and the time domain).

[0208] If the second interval is used for time domain isolation or frequency domain isolation, which can already achieve a good isolation effect, the resources required for isolation can be reduced, thereby improving the effective use of resources.

[0209] If the second interval is used for time domain isolation and frequency domain isolation, this can effectively achieve isolation between different transmissions, reduce interference within the first terminal, protect the hardware of the first terminal, and provide sufficient conversion time for changing the transmission type of the first terminal to ensure the communication quality of various transmissions.

[0210] In some embodiments, the first resource is dedicated to BS reception, and the first terminal does not perform UL transmission, does not perform DL reception, and does not perform CW transmission on the first resource.

[0211] In some embodiments, the first resource is dedicated to BS reception, and the first terminal does not perform UL transmission, does not perform DL reception, and does not perform CW transmission on the first resource and within the third interval; the third interval is used for frequency domain isolation of BS reception and at least one of UL transmission, DL reception, and CW transmission; and / or, the second interval is used for time domain isolation of BS reception and at least one of UL transmission, DL reception, and CW transmission.

[0214] In some embodiments, the third interval is used for protection of the frequency domain and the time domain (or for isolation of the frequency domain and the time domain).

[0215] If the third interval is used for time domain isolation or frequency domain isolation, a good isolation effect can be achieved, and the resources required for isolation can be reduced, thereby improving the effective use of resources.

[0216] If the third interval is used for time domain isolation and frequency domain isolation, this can, on the one hand, achieve good isolation between different transmissions, reduce interference within the first terminal, protect the hardware of the first terminal, and provide sufficient conversion time for changing the transmission type of the first terminal, thereby ensuring the communication quality of various transmissions.

[0217] In some embodiments, the first interval, the second interval and the third interval can all be protection intervals. On the one hand, the introduction of the protection interval can avoid mutual interference caused by untimely switching of different types of transmissions of the first terminal. On the other hand, it can reduce damage to hardware equipment caused by failure to stop a certain type of transmission in time.

[0218] In some embodiments, the configuration information includes at least one of the following:

[0219] Time information, used to indicate the time position of the first resource;

[0220] Timing reference information, used to indicate a reference timing of the first resource;

[0221] Frequency domain information, used to indicate the frequency domain position of the first resource;

[0222] Cell information, used to indicate the cell corresponding to the first resource;

[0223] The validity period information is used to indicate the validity period of the first resource.

[0224] The time information may include absolute time, identifiers of various time units, etc. The time units here may include: time slots, mini-time slots, symbols, etc.

[0225] In some embodiments, the timing reference information may provide a reference timing corresponding to the time information. Specifically, the timing reference information may include a cell identifier. The cell identifier indicates that the reference timing is based on a clock of the corresponding cell.

[0226] In some embodiments, the timing reference signal may further include a time offset value, and the time offset value and the cell identifier are used together to determine the reference timing.

[0227] In some embodiments, the time information includes at least one of the following:

[0229] An offset, used to indicate the time interval between the time domain starting position of the first first resource and the time instant of receiving the configuration information;

[0243] In some embodiments, the configuration information may be semi-static information, and in this case the first resource is a semi-static configuration resource.

[0244] S2103: The first terminal sends a second message to the network device.

[0245] In some embodiments, the second message is sent to the network device before the validity period of the currently configured first resource expires.

[0246] In some embodiments, the second message is used to request the network device to extend the validity period of the first resource.

[0247] In some embodiments, the second message may be used to request an extension of the validity period of the first resource.

[0248] In some embodiments, the second message may be an RRC message, a MAC layer message, or UCI.

[0249] In some embodiments, the second message includes at least one of the following:

[0250] An extension request, used to request the network device to extend the validity period of the first resource;

[0251] The first validity period information is used to determine the extended validity period of the first resource to the network device.

[0252] In some embodiments, the second message may include an extension request. The duration of the first resource's validity period extension may be determined by the network device or according to a protocol agreement. For example, the network device may determine to extend the first resource's validity period by one or half the validity period based on the extension request. In other words, the first validity period information is optional content in the second message.

[0253] In some embodiments, the second message may include the first validity period information but not the extension request. The fact that the second message carries the first validity period information implicitly indicates that the first terminal requests an extension of the validity period of the first resource, and the requested extension duration is the duration indicated by the first validity period information.

[0254] S2104: The network device sends a third message to the first terminal.

[0255] In some embodiments, the third message is used to indicate to the first terminal whether to allow extension of the validity period of the first resource.

[0256] In some embodiments, the network device sends a third message to the first terminal based on the second message.

[0257] In some embodiments, the third message may be an acceptance message indicating acceptance of the extension of the first resource.

[0258] In some embodiments, the third message may be a rejection message indicating rejection of the extension of the first resource.

[0259] In some embodiments, the third message includes at least one of the following:

[0260] An extension indication, used to indicate to the first terminal whether to allow the validity period of the first resource to be extended;

[0261] The second validity period information is used to indicate the extended validity period of the first resource to the first terminal.

[0262] In some embodiments, the third message may carry an extension indication but not the second validity period information, and the extension period of the first resource validity period may be determined according to a protocol or by default.

[0263] In some embodiments, the third message may carry the second validity period information but not an extension indication, in which case the extension of the first resource is allowed by default and the extension duration is indicated by the second validity period information.

[0264] S2105: The first terminal releases the first resource.

[0265] In some embodiments, when the validity period of the first resource expires, the first resource is released. In one example, the first terminal requests the network device to extend the validity period, and the network device agrees to extend the validity period. At this time, the limited period of the first resource expires when the extended validity period expires.

[0266] In some embodiments, the first resource is released in advance when CW transmission and / or BS reception is completed.

[0267] By releasing the first resource, it is convenient for the network device to schedule transmission on the Uu port, thereby improving the effective utilization rate of the first resource.

[0268] It is worth noting that one or more of the above S2101, S2103 to S2105 can be optional steps. The network device can automatically configure the first resource without the first terminal requesting or providing resource information for the first resource configuration, and the first message and / or the fifth message can be omitted. After receiving the configuration information of the first resource, the first terminal uses the first resource for CW transmission and / or BS reception without extending the use of the first resource, and the steps related to the transmission of the second message and the third message can be omitted. When the validity period of the first resource expires, the network device can automatically reclaim the first resource without the first terminal releasing it, so S2105 can also be omitted.

[0269] As shown in FIG2B , an embodiment of the present disclosure provides another resource configuration method, which is performed by a communication system. The method may include:

[0270] S2201: The first terminal sends a message to the network device.

[0271] In some embodiments, the first terminal may serve as a first terminal providing an excitation signal to a second terminal and / or a device receiving a signal sent by a BS from the second terminal. For example, the first terminal may serve as an auxiliary node, intermediate node, relay node, or other device for an ambient energy IoT device.

[0272] Exemplarily, the second terminal may be an ambient IoT device. Exemplarily, the second terminal may be device A, device B, and / or device C as shown in FIG1H .

[0273] For example, the first terminal can serve as an intermediate node, auxiliary node, relay node, or other device for an ambient energy IoT device. The first terminal can serve as an intermediate node as shown in FIG1D . Alternatively, the first terminal can serve as an auxiliary node as shown in FIG1E and / or FIG1F . The first terminal can also be a terminal as shown in FIG1G .

[0274] In some embodiments, the first terminal sends the fourth message and / or the fifth message to the network device.

[0275] In some embodiments, the fourth message and the fifth message may be the same message.

[0276] In some embodiments, the fourth message and the fifth message may be different messages.

[0277] In some embodiments, the fourth message is used to request a one-time (one short) resource.

[0288] The first resource is suggested to be used for CW transmission and / or BS reception;

[0289] The recommended cell where the first resource is located.

[0290] In some embodiments, the first terminal may provide resource information for configuring the second resource to the network device via a fifth message. The resource information for the second resource may be used by the network device to configure the first resource for the terminal. For example, the network device may select some or all of the second resource to configure the first terminal.

[0298] It is worth noting that the information content of the fifth message here can refer to the relevant description of the embodiment corresponding to Figure 2A.

[0299] S2202: The network device sends configuration information.

[0300] In some embodiments, the configuration information is used at least to configure the first resource.

[0301] In some embodiments, the first resource is used for continuous wave (CW) transmission and / or backscatter BS reception at the first terminal.

[0302] In some embodiments, the CW transmission is used to provide an excitation signal to the second terminal.

[0303] For example, the first resource may be used solely for CW transmission by the first terminal, the first resource may be used solely for BS reception by the first terminal, or the first resource may be used for both CW transmission and BS reception by the first terminal.

[0304] In some embodiments, the excitation signal may be used to provide energy to the second terminal.

[0305] Exemplarily, the second terminal may include but is not limited to the aforementioned environmental Internet of Things device, specifically the device shown in Figures 1C to 1E.

[0306] In some embodiments, the network device sends an RRC message, a MAC layer message, or downlink control information (DCI) carrying configuration information.

[0307] The first resource is used for CW transmission and / or BS reception, and the first terminal does not perform uplink UL transmission and downlink DL reception on at least the first resource.

[0308] In some embodiments, the first resource is not used for UL transmission and DL reception of the first terminal, and both UL transmission and DL reception are Uu port transmission, which can at least reduce interference between Uu transmission and CW transmission and / or BS reception.

[0309] In some embodiments, the first resource is used for CW transmission and / or BS reception, and the first terminal does not perform UL transmission and does not perform DL reception on the first resource and in the first interval.

[0310] The first interval is used for frequency domain isolation of CW transmission from at least one of UL transmission and DL reception; and / or the first interval is used for time domain isolation of BS reception from at least one of UL transmission and DL reception.

[0311] In some embodiments, the first interval is used for frequency domain protection (or for frequency domain isolation).

[0312] In some embodiments, the first interval is used for time domain protection (or for time domain isolation).

[0313] In some embodiments, the first interval is used for protection of the frequency domain and the time domain (or for isolation of the frequency domain and the time domain).

[0314] If the first interval is used for time domain isolation or frequency domain isolation and can achieve a good isolation effect, the resources required for isolation can be reduced, thereby improving the effective use of resources.

[0315] If the first interval is used for time domain isolation and frequency domain isolation, this can effectively achieve isolation between different transmissions, reduce interference within the first terminal, protect the hardware of the first terminal, and provide sufficient conversion time for changing the transmission type of the first terminal to ensure the communication quality of various transmissions.

[0316] In some embodiments, the first resource is dedicated to CW transmission, and the first terminal does not perform UL transmission, DL reception, or BS reception on the first resource.

[0317] If the first resource is dedicated to CW transmission, the first resource is not used for UL transmission, DL reception, and BS reception, which can maximize the CW transmission without interference.

[0318] In some embodiments, the first resource is dedicated to CW transmission, and the first terminal does not perform UL transmission, does not perform DL reception, and does not perform BS reception on the first resource and within the second interval; the second interval is used for frequency domain isolation of CW transmission and at least one of UL transmission, DL reception, and BS reception; and / or, the second interval is used for time domain isolation of BS reception and at least one of UL transmission, DL reception, and BS reception.

[0319] In some embodiments, the second interval is used for frequency domain protection (or for frequency domain isolation).

[0320] In some embodiments, the second interval is used for time domain protection (or for time domain isolation).

[0321] In some embodiments, the second interval is used for protection of the frequency domain and the time domain (or for isolation of the frequency domain and the time domain).

[0322] If the second interval is used for time domain isolation or frequency domain isolation, which can already achieve a good isolation effect, the resources required for isolation can be reduced, thereby improving the effective use of resources.

[0323] If the second interval is used for time domain isolation and frequency domain isolation, this can effectively achieve isolation between different transmissions, reduce interference within the first terminal, protect the hardware of the first terminal, and provide sufficient conversion time for changing the transmission type of the first terminal to ensure the communication quality of various transmissions.

[0324] In some embodiments, the first resource is dedicated to BS reception, and the first terminal does not perform UL transmission, does not perform DL reception, and does not perform CW transmission on the first resource.

[0325] In some embodiments, the first resource is dedicated to BS reception, and the first terminal does not perform UL transmission, does not perform DL reception, and does not perform CW transmission on the first resource and within the third interval; the third interval is used for frequency domain isolation of BS reception and at least one of UL transmission, DL reception, and CW transmission; and / or, the second interval is used for time domain isolation of BS reception and at least one of UL transmission, DL reception, and CW transmission.

[0326] In some embodiments, the third interval is used for frequency domain protection (or for frequency domain isolation).

[0327] In some embodiments, the third interval is used for time domain protection (or for time domain isolation).

[0328] In some embodiments, the third interval is used for protection of the frequency domain and the time domain (or for isolation of the frequency domain and the time domain).

[0329] If the third interval is used alone for time domain isolation or frequency domain isolation, a good isolation effect can be achieved, and the resources required for isolation can be reduced, thereby improving the effective use of resources.

[0330] If the third interval is used for both time domain isolation and frequency domain isolation, this can effectively achieve isolation between different transmissions, reduce interference within the first terminal, protect the hardware of the first terminal, and provide sufficient conversion time for changing the transmission type of the first terminal, thereby ensuring the communication quality of various transmissions.

[0331] In some embodiments, the first interval, the second interval and the third interval can all be protection intervals. On the one hand, the introduction of the protection interval can avoid mutual interference caused by the untimely switching of different types of transmissions of the first terminal. On the other hand, it can reduce the damage to the hardware equipment caused by the failure to stop a certain type of transmission in time.

[0332] In some embodiments, the configuration information includes at least one of the following:

[0345] S2203: The first terminal releases the first resource.

[0346] For example, the first terminal automatically releases the first resource when the duration of the first resource expires.

[0347] For another example, if the first terminal completes sending and / or the BS completes receiving in advance, the first resource may be released in advance.

[0348] It is worth noting that one or more of S2201 and S2203 above may be optional. If the network device can automatically configure the first resource without the first terminal requesting or providing resource information for the second resource, the fourth and / or fifth messages may be omitted. After the duration of the first resource expires, the network device can automatically reclaim the first resource without requiring the first terminal to release it, so S2203 may also be omitted.

[0427] As shown in FIG4B , another resource configuration method provided by an embodiment of the present disclosure is performed by a first terminal and includes:

[0428] S4201: Receive message.

[0429] In some embodiments, the network device receives the fourth message and / or the fifth message sent by the first terminal.

[0430] In some embodiments, the fourth message may be used by the first terminal to request a one-time first resource from the network device.

[0431] In some embodiments, the fifth message may be used by the first terminal to provide resource information of the second resource to the network device.

[0433] In some embodiments, the relevant description of the first message and / or the fifth message here can refer to the relevant description of the corresponding embodiment of Figure 2B.

[0434] S4202: Send configuration information of the first resource.

[0435] In some embodiments, the configuration information includes at least one of the following: time information, used to indicate the time position of the first resource; timing reference information, used to indicate the reference timing of the first resource; frequency domain information, used to indicate the frequency domain position of the first resource; cell information, used to indicate the cell corresponding to the first resource.

[0436] In some embodiments, the time information includes at least one of the following: period information, used to indicate the period of the first resource; an offset, used to indicate the time interval between the time domain starting position of the first first resource and the moment of receiving the configuration information; and duration information, used to indicate the duration of a first resource.

[0437] It is worth noting that: for optional embodiments of step S4201, reference may be made to any optional embodiment of the embodiment corresponding to FIG2B , for example, the network device may automatically configure a one-time first resource for the terminal.

[0438] If the terminal acts as a reader and supports data transmission with an ambient IoT device within the DL bandwidth or UL bandwidth on the terminal's Uu port, there will be an intra-terminal interference problem.

[0439] The embodiments of the present disclosure are directed to a terminal as a reader, supporting data transmission with an ambient IoT device within the DL bandwidth or UL bandwidth on the Uu port of the terminal, and how to avoid interference within the terminal to make terminal communication and communication between the terminal and a tag efficient, thereby improving data transmission and reception reliability.

[0440] Figures 5A to 5D respectively provide several examples of interference within the terminal:

[0441] Scenario 1: In the scenario shown in FIG5A , the terminal performs UL transmission on the UL frequency band, and at the same time, the terminal performs CW transmission and backscatter reception on the UL frequency band. Therefore, the UL transmission will at least result in backscatter reception.

[0442] Scenario 2: In the scenario shown in Figure 5B , the terminal operates on the UL band and performs UL transmission. Simultaneously, the terminal performs backscatter reception on the UL band. In this case, CW transmission can be specified by another device or node. Similarly, UL transmission will at least include backscatter reception.

[0443] Scenario (case) 3: In the scenario shown in FIG5C , the terminal operates in the DL frequency band to perform DL reception, and at the same time the terminal performs CW transmission and backscatter reception in the DL frequency band. Therefore, the DL reception includes at least backscatter reception.

[0444] Scenario 4: In the scenario shown in Figure 5D, the terminal operates on the DL band and performs DL reception. Simultaneously, the terminal performs backscatter reception on the DL band. In this case, CW transmission can be specified by another device or node. Similarly, DL reception will at least include backscatter reception.

[0445] In view of the above-mentioned interference within the terminal, several implementation methods are provided to reduce the interference within the terminal. It is worth noting that if a terminal needs to perform CW transmission and BS reception at the same time, there will be mutual interference between the CW transmission and the BS reception.

[0446] Solution 1: For scenarios 1 to 4, the terminal's DL reception and / or UL transmission of resource requests can interfere with the backscatter of IoT devices in the environment.

[0447] Option 1: The network side semi-statically configures a periodic window or gap for the terminal through RRC signaling. The periodic window or gap is used for the terminal to implement the reader function on the DL or UL spectrum.

[0448] For example, sending an excitation signal CW to the ambient energy Internet of Things device, and / or receiving the signal / information reflected back by the ambient energy Internet of Things device.

[0449] Configuration parameters of the periodic window or gap include but are not limited to: period, offset, and duration.

[0450] The timing reference of the periodic window or gap is a serving cell, which is the primary cell (PCell) by default.

[0451] Furthermore, the periodic window or gap is also associated with a serving cell identifier (ID). In this case, the spectrum resources used to communicate with the ambient IoT device use the DL spectrum or UL spectrum resources of the cell corresponding to the serving cell ID.

[0452] Furthermore, the network side may also configure which portion of the DL or UL spectrum resources is used for CW transmission and / or BS reception, for example, a BWP configuration, which is used for CW transmission and / or BS reception.

[0453] The network may also indicate the total duration of the resource allocation. If the duration expires and the terminal expects to continue using the allocated time and / or frequency domain resources for CW transmission and / or BS reception, the terminal may request the network to extend the resource occupation and may provide a recommended extension duration.

[0454] If the time expires, the resource occupation is automatically released.

[0455] Option 2: The terminal acts as a reader and communicates with surrounding IoT devices, for example, providing CW transmission and / or base station reception capabilities. The terminal then requests the network to allocate frequency and / or time domain configuration information. The terminal can also provide frequency and / or time domain configuration information that it recommends or prefers.

[0456] The request information can be carried in the UE Assistance Information message. The request information can include a recommended BWP configuration information for providing the terminal's preferred frequency domain resources and a periodic window information, including the period, offset value, duration, etc., for providing the terminal's preferred time domain resources.

[0457] At the same time, the terminal may also request the total duration of occupying time domain and / or frequency domain resources.

[0458] The network semi-statically configures a periodic window or gap for the terminal through RRC signaling. The periodic window and gap are used by the terminal to implement reader functions on the DL or UL spectrum, such as sending a CW excitation signal to an ambient IoT device and / or receiving signals / information reflected from the ambient IoT device. Configuration parameters for the periodic window or gap include, but are not limited to, period, offset, and / or duration. The timing reference of the periodic window or gap is a serving cell, which defaults to the PCell.

[0459] Furthermore, the periodic window or gap is also associated with a serving cell ID. In this case, the spectrum resources used to communicate with the ambient IoT device use the DL spectrum or UL spectrum resources of the cell corresponding to the serving cell ID.

[0460] Furthermore, the network side can also configure which part of the DL or UL spectrum resources is used for CW transmission and / or BS reception, for example, it can be a BWP configuration, and the BWP configuration is used for CW transmission and / or BS reception.

[0461] Furthermore, the network may also indicate the total duration of resource allocation. If the duration expires and the terminal desires to continue using the allocated time and / or frequency domain resources for CW transmission and / or BS reception, the terminal may request the network to extend the resource occupation and may provide a recommended extension duration. If the duration expires, the resource occupation is automatically released.

[0462] Option 3: The terminal may also request one short resource (time domain and / or frequency domain resource) for CW transmission and / or BS reception.

[0463] Solution 2: Interference avoidance for scenarios 1 / 2 / 3 / 4 where DL / UL interference from ambient IoT devices interferes with backscatter

[0464] Option 1: For scenarios 1 / 2, based on the solution in solution 1, when the network side is scheduling, it cannot schedule the terminal's UL during the time period used for communication with ambient IoT devices.

[0465] Option 2: For scenarios 3 / 4, based on the solution in solution 1, when the network is scheduling, it cannot schedule the terminal's DL during the time period used for communication with ambient IoT devices. Alternatively, when scheduling DL, the network cannot schedule time-frequency resources that are too close to the communication resources with ambient IoT devices. The specific distance can be determined based on auxiliary parameters reported by the terminal. For example, the terminal reports auxiliary parameters, which are the minimum time domain interval from the communication resources of the ambient IoT device in the time domain, such as a number of slots, and / or the minimum frequency domain interval from the communication resources of the ambient IoT device in the frequency domain, such as a number of RBs / PRBs. Optionally, a reference subcarrier spacing (SCS) can also be provided. The SCS is used to measure the actual spacing size in the frequency domain.

[0466] Solution 3: For scenario 1 / 3, the interference problem of the CW excitation signal on the backscatter of the ambient energy IoT device

[0467] Option 1: Based on options 1 and 2, if dedicated resources are allocated to the terminal for transmitting CWs when used as a reader, the terminal can report the minimum time domain interval and / or minimum frequency domain interval to the network to avoid CW interference on the BS. The network then configures dedicated resources for BS reception, achieving better time-frequency and / or frequency domain isolation, reducing or eliminating CW interference on the BS. The dedicated resources configured for BS reception can be periodic resources or one-shot resources. If it is a periodic resource, the network also indicates the resource period, offset, and the resource occupied PRB (resource onduration).

[0468] Option 2: Based on options 1 and 2, if dedicated resources are allocated to the terminal for transmitting CWs used as a reader and / or for the BS to receive CWs, a certain time domain separation and / or frequency domain isolation is guaranteed based on the terminal to avoid interference.

[0469] The embodiments of the present disclosure are directed to a terminal as a reader, supporting data transmission with an ambient IoT device within the DL bandwidth or UL bandwidth on the Uu port of the terminal, and how to avoid interference within the terminal, so as to make terminal communication and communication between the terminal and the tag efficient and improve data transmission and reception reliability.
