Description

Wireless communication method, communication device and storage medium Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a wireless communication method, communication equipment, and storage medium. Background Art

[0002] Traditional IoT devices are typically powered by conventional batteries with limited lifespans. If the batteries run out, the device becomes unusable, requiring battery replacement or even replacement. Maintaining IoT network operations and replacing batteries can be challenging in extreme environments.

[0044] Based on the above solution, by introducing priority, resource conflicts can be resolved when the first transmission and the second transmission share the same frequency band, thereby standardizing the first transmission and / or the second transmission and improving the communication quality of the first transmission and / or the second transmission.

[0045] In some embodiments of the first aspect, resources of the first transmission and the second transmission conflict, and the execution of the first transmission or the second transmission is determined according to the priority of the first transmission and / or the priority of the second transmission, including: there is a resource conflict between the first resource of the first transmission and the second resource of the second transmission and the first device does not support the simultaneous execution of the first transmission and the second transmission, and the execution of the first transmission or the second transmission is determined according to the priority of the first transmission and / or the priority of the second transmission; the first resource belongs to the first frequency band; the second resource belongs to the first frequency band.

[0046] Based on the above solution, when the first terminal does not support the simultaneous execution of the first transmission and the second transmission, the execution of the first transmission and / or the second transmission is determined according to the priority. This is equivalent to when the first terminal supports the execution of the first transmission and the second transmission at the same time. In this case, the first terminal can execute the first transmission and the second transmission at the same time, thereby ensuring the transmission quality while improving the effective utilization of resources.

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.

[0126] In some embodiments, the core network device may be a single device including a first network element, or may be multiple 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).

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

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] Backscatter transmission network architectures can include but are not limited to the following:

[0138] 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.

[0139] 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).

[0140] 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).

[0141] 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.

[0142] Ambient IoT devices are all capable of performing reflection and scattering. In some embodiments, ambient IoT devices can be classified based on whether they can amplify signals. In some embodiments, ambient IoT devices can be classified based on whether they can generate their own signals, rather than relying solely on reflection and scattering signals.

[0143] 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:

[0144] Type A: No energy storage, cannot generate or amplify signals independently, and can only perform backscatter transmission.

[0145] Type B: Has energy storage, cannot generate signals independently, and can only perform backscatter transmission. The use of stored energy can include amplification of the backscatter signal.

[0146] Type C: It has energy storage and can generate signals independently, that is, it has active radio frequency (RF) components for transmission.

[0147] As shown in FIG2A , an embodiment of the present disclosure provides a wireless communication method, which is performed by a communication system. The method may include:

[0148] S2101: The network device receives capability information of the first terminal.

[0149] In some embodiments, the network device may be an access network device.

[0150] In some embodiments, the capability information is used to indicate whether the first device supports performing the first transmission and the second transmission simultaneously.

[0151] In some embodiments, the first transmission and the second transmission share the same frequency band (eg, the first frequency band), and the network device obtains capability information of the first device.

[0152] For example, the first frequency band may be any frequency band in various frequency ranges, for example, the first frequency band belongs to frequency range 1 (FR1) and / or frequency range 2 (FR2) or other frequency ranges.

[0153] In some embodiments, the first transmission includes continuous wave (CW) transmission and / or backscattered base station (BS) reception by the first device to the second terminal. Exemplarily, the second terminal may be the aforementioned ambient IoT device. For example, the second terminal may be any of the types of devices shown in FIG. 1H . Exemplarily, the first device may include, but is not limited to, a first terminal.

[0154] In some embodiments, the second transmission includes uplink (UL) transmission and / or downlink (DL) reception between the first terminal and the network device.

[0155] In some embodiments, the first device includes a network device and / or a first terminal.

[0156] In some embodiments, the first terminal may be a terminal supporting LTE and / or NR. For example, a typical first terminal may include but is not limited to: a mobile phone, a tablet computer, a wearable device, an in-vehicle device, or a mobile robot.

[0157] In some embodiments, the first device is a network device, and the network device obtains its own capability information.

[0158] In some embodiments, the first device is a first terminal, and the network device receives the capability information sent by the first terminal. Exemplarily, the first terminal sends the capability information to the network device when it is in a connected state. For example, the first terminal sends its own capability information through an RRC message, MAC signaling, or uplink control information (UCI) in the connected state. For another example, the first terminal sends its own capability information to the network device through an RRC connection release request message. For another example, the first terminal sends its own capability information through user assistance information (UAI).

[0159] In some embodiments, the first device is a first terminal, and the network device may obtain the capability information of the first terminal according to the model of the first terminal or from a device server of the first terminal.

[0160] S2102: The network device configures the priority of the first transmission and / or the priority of the second transmission.

[0161] In some embodiments, the network device configures the priority of the first transmission and / or the priority of the second transmission according to the first configuration and / or the second configuration.

[0162] In some embodiments, the first configuration is used to configure a first transmission. Exemplarily, the first configuration is used for a first device to perform the first transmission.

[0163] In some embodiments, the first configuration is at least used to configure a first resource. The first resource may be a time-frequency domain resource for the first transmission.

[0164] In some embodiments, the second configuration is used to configure the second transmission. Exemplarily, the second configuration is used for the first device to perform the second transmission.

[0165] In some embodiments, the second configuration is at least used to configure a second resource. The second resource may be a time-frequency domain resource of the first transmission.

[0166] Exemplarily, when the network device determines that the first resource and the second resource have a resource conflict according to the first configuration and the second configuration, the network device performs priority configuration of the first transmission and / or the second transmission.

[0167] In some embodiments, the first resource and the second resource having a resource conflict may include: the first resource and the second resource having overlapping positions in the time domain and / or frequency domain. If the first resource and the second resource have overlapping positions in the time domain, then the first resource and the second resource have a resource conflict in the time domain. If the first resource and the second resource have overlapping positions in the frequency domain, then the first resource and the second resource have a resource position in the frequency domain.

[0168] In some embodiments, when there is a resource conflict between the first resource and the second resource, the network device configures the priority of the first transmission and / or the priority of the second transmission according to the first information.

[0169] In some embodiments, the first device is a first terminal, the first transmission and the second transmission share a first frequency band, and whether to configure the priority of the first transmission and / or the priority of the second transmission is determined according to the capability of the first terminal.

[0170] In some embodiments, when configuring the first resource and / or the second resource, the network device determines that there is a resource conflict between the first resource and the second resource, and then the network device configures the priority of the first transmission and / or the priority of the second transmission according to the first information.

[0171] Exemplarily, when configuring the first resource and / or the second resource, the network device determines that there is a resource conflict between the first resource and the second resource and the first information indicates that the first terminal does not support simultaneous execution of the first transmission and the second transmission, then configures the priority of the first transmission and / or the priority of the second transmission.

[0172] For example, if the first transmission for which resources have been configured is not configured with a priority and the priority of the second transmission to be configured is higher than the priority of the first transmission, the priority of the first transmission can be configured and the priority of the second transmission can be configured, and the priority of the second transmission can be configured to be higher than the priority of the first transmission.

[0173] For another example, if a first transmission for which resources have been configured is not configured with a priority and a second transmission to be configured has a higher priority than the first transmission, the priority of the second transmission may be configured, and the priority of the second transmission may be configured to be any priority higher than the lowest priority. For example, any priority higher than the lowest priority may be the highest priority. In this case, if the first device does not receive the priority of the first transmission, the priority of the first transmission at the corresponding position may be assumed to be the lowest priority.

[0174] For another example, in some embodiments, if the first resource and the second resource have a resource conflict and the first device does not support simultaneous execution of the first transmission and the second transmission, the priority of the first transmission and / or the priority of the second transmission can be configured according to the type of the second transmission at the resource conflict.

[0175] In some embodiments, configuring the priority of the first transmission and / or the priority of the second transmission based on the type of the second transmission at the resource conflict may include:

[0176] If the second transmission at the resource conflict location is a transmission of a specified type, the priority of the second transmission is configured to be higher than the priority of the first transmission;

[0177] If the second transmission at the resource conflict is not a transmission of the specified type, the priority of the second transmission is configured to be lower than the priority of the first transmission.

[0178] In some embodiments, the specified type may include a common signal and / or a common message. For example, a typical common signal may include a cell-level reference signal and / or a user equipment (UE) group-level reference signal. The common message may include: cell broadcast information and / or multicast information. The broadcast information may include, but is not limited to, system information. The system information may include, but is not limited to, a master information block (MIB) and / or a system information block (SIB). Exemplarily, the broadcast information may also include some broadcast service data, etc.

[0179] The priority of the first transmission is lower than the priority of the common signal in the second transmission; and / or,

[0180] The priority of the first transmission is lower than the priority of the system information in the second transmission; and / or,

[0181] The priority of the first transmission is lower than the priority of the paging message in the second transmission; and / or,

[0182] The priority of the first transmission is lower than the priority of random access of the second transmission.

[0183] In some embodiments, random access may include two-step random access and / or four-step random access.

[0184] In some embodiments, the random access comprises a random access request.

[0185] The common signal includes at least: a synchronization signal broadcast block SSB.

[0186] In some embodiments, if the first information indicates that the first device supports simultaneous execution of the first transmission and the second transmission, the priority of the first transmission and / or the second transmission may not be used.

[0187] In some embodiments, the CW transmission is configured on the UL spectrum of the first frequency band.

[0188] In some embodiments, the BS receives a UL spectrum configured in a first frequency band.

[0189] In some embodiments, the CW transmission is configured on a DL spectrum of a first frequency band.

[0190] In some embodiments, the BS receives a DL spectrum configured on a first frequency band.

[0191] In some embodiments, both CW transmission and BS reception are configured on the UL spectrum of the first frequency band.

[0192] In some embodiments, both CW transmission and BS reception are configured on a DL spectrum of the first frequency band.

[0193] In some embodiments, CW transmission is configured on a UL spectrum of a first frequency band and BS reception is configured on a DL spectrum of the first frequency band.

[0194] In some embodiments, CW transmission is configured on a DL spectrum of a first frequency band and BS reception is configured on a UL spectrum of the first frequency band.

[0195] S2103: The network device sends priority information to the first terminal.

[0196] In some embodiments, the priority information includes first priority information and / or second priority information.

[0197] The first priority information indicates a priority of the first transmission. The second priority information indicates a priority of the second transmission.

[0198] In some embodiments, the network device sends the priority information to the first terminal in the first configuration and / or the second configuration. For example, the first priority information is carried in the first configuration, and the second priority information is carried in the second configuration.

[0199] In some embodiments, the network device sends the priority information to the first terminal using a downlink message different from the downlink message carrying the first configuration and / or the second configuration.

[0200] In some embodiments, an RRC message, a MAC message, or a DCI is sent containing the priority information.

[0201] In some embodiments, the priority information may include first priority information and / or second priority information. The first priority information indicates the priority of the first transmission. The second priority information indicates the priority of the second transmission.

[0202] In some embodiments, the priority of the first transmission and / or the second transmission may be determined by a protocol agreement or a preset method. In this case, S2102 and S2103 may be optional steps. For another example, if the first device supports simultaneous execution of the first transmission and the second transmission, the priority of the first transmission and / or the second transmission may not be determined, and steps S2102 and S2103 may also be omitted.

[0203] In some embodiments, the priority is configured by the network device.

[0204] In other embodiments, the priority is determined by protocol.

[0205] In some embodiments, the first terminal supports simultaneous first and second transmissions, and the first and second resources have a guard interval in the frequency domain. In this case, the network device considers the introduction of the guard interval when configuring the first and second configurations, so that the first and second resources have a certain frequency interval in the frequency domain at the overlapping position in the time domain.

[0206] S2104: There is a resource conflict between the first transmission and the second transmission. Determine whether to perform the first transmission or the second transmission according to the priority of the first transmission and / or the priority of the second transmission.

[0212] In some embodiments, the first transmission and the second transmission share a first frequency band and resources of the first transmission and the second transmission conflict. The first transmission or the second transmission with a higher priority is performed at the resource conflict location according to the priority, and the second transmission or the first transmission with a lower priority is discarded.

[0213] In some embodiments, the first transmission and the second transmission share a first frequency band, there is a resource conflict between the first resource of the first transmission and the second resource of the second transmission, and the second transmission is a random access transmission, and the random access transmission is performed according to priority.

[0214] In some embodiments, the random access transmission is used to cause the first terminal to switch from the first state to the second state.

[0215] In some embodiments, the first state includes a radio resource control (RRC) idle state and / or an RRC inactive state.

[0216] In some embodiments, the second state comprises an RRC connected state.

[0261] Exemplarily, when the network device determines that the first resource and the second resource have a resource conflict according to the first configuration and the second configuration, the network device performs priority configuration of the first transmission and / or the second transmission.

[0262] In some embodiments, the first resource and the second resource having a resource conflict may include: the first resource and the second resource having overlapping positions in the time domain and / or the frequency domain.

[0263] In some embodiments, when there is a resource conflict between the first resource and the second resource, the network device configures the priority of the first transmission and / or the priority of the second transmission according to the first information.

[0264] In some embodiments, when configuring the first resource and / or the second resource, the network device determines that there is a resource conflict between the first resource and the second resource, and then the network device configures the priority of the first transmission and / or the priority of the second transmission according to the first information.

[0265] Exemplarily, when configuring the first resource and / or the second resource, the network device determines that there is a resource conflict between the first resource and the second resource and the first information indicates that the terminal does not support simultaneous execution of the first transmission and the second transmission, then configures the priority of the first transmission and / or the priority of the second transmission.

[0266] For example, if the first transmission for which resources have been configured is not configured with a priority and the priority of the second transmission to be configured is higher than the priority of the first transmission, the priority of the first transmission can be configured and the priority of the second transmission can be configured, and the priority of the second transmission can be configured to be higher than the priority of the first transmission.

[0267] For another example, if a first transmission for which resources have been configured is not configured with a priority and a second transmission to be configured has a higher priority than the first transmission, the priority of the second transmission may be configured, and the priority of the second transmission may be configured to be any priority higher than the lowest priority. For example, any priority higher than the lowest priority may be the highest priority. In this case, if the first device does not receive the priority of the first transmission, the priority of the first transmission at the corresponding position may be assumed to be the lowest priority.

[0268] For another example, in some embodiments, if the first resource and the second resource have a resource conflict and the first device does not support simultaneous execution of the first transmission and the second transmission, the priority of the first transmission and / or the priority of the second transmission can be configured according to the type of the second transmission at the resource conflict.

The first transmission or the second transmission with a higher priority is performed at the resource conflict location according to the priority, and the second transmission or the first transmission with a lower priority is discarded.

[0293] In some embodiments, the first transmission and the second transmission share a first frequency band, there is a resource conflict between the first resource of the first transmission and the second resource of the second transmission, and the second transmission is a random access transmission, and the random access transmission is performed according to priority.

[0309] For example, the first frequency band may be any frequency band in various frequency ranges, for example, the first frequency band belongs to frequency range 1 (FR1) and / or frequency range 2 (FR2) or other frequency ranges.

[0310] In some embodiments, the first transmission includes a continuous wave (CW) transmission and / or backscattered BS reception by the first terminal to the second terminal. For example, the second terminal may be the aforementioned ambient IoT device. For example, the second terminal may be any of the types of devices shown in FIG. 1H .

[0311] In some embodiments, the second transmission includes uplink (UL) transmission and / or downlink (DL) reception between the first terminal and the network device.

[0312] S3102: Configure the priority of the first transmission and / or the priority of the second transmission.

[0313] In some embodiments, the first transmission and the second transmission share the same frequency band (eg, the first frequency band), and the priority of the first transmission and / or the priority of the second transmission are configured.

[0314] In some embodiments, the network device configures the priority of the first transmission and / or the priority of the second transmission according to the first configuration and / or the second configuration.

[0315] In some embodiments, the first configuration is used to configure a first transmission. Exemplarily, the first configuration is used for a first terminal to perform the first transmission.

[0316] In some embodiments, the first configuration is at least used to configure a first resource. The first resource may be a time-frequency domain resource for the first transmission.

[0318] In some embodiments, the second configuration is at least used to configure a second resource. The second resource may be a time-frequency domain resource of the first transmission.

[0319] Exemplarily, when the network device determines that the first resource and the second resource have a resource conflict according to the first configuration and the second configuration, the network device performs priority configuration of the first transmission and / or the second transmission.

[0320] In some embodiments, the first resource and the second resource having a resource conflict may include: the first resource and the second resource having overlapping positions in the time domain and / or the frequency domain.

[0321] In some embodiments, when there is a resource conflict between the first resource and the second resource, the network device configures the priority of the first transmission and / or the priority of the second transmission according to the first information.

[0322] In some embodiments, the first device is a first terminal, the first transmission and the second transmission share a first frequency band, and whether to configure the priority of the first transmission and / or the priority of the second transmission is determined according to the capability of the first terminal.

For example, any priority higher than the lowest priority may be the highest priority. In this case, if the first terminal does not receive the priority of the first transmission, the priority of the first transmission at the corresponding position may be assumed to be the lowest priority.

[0327] For another example, in some embodiments, if the first resource and the second resource have a resource conflict and the first terminal does not support simultaneous execution of the first transmission and the second transmission, the priority of the first transmission and / or the priority of the second transmission can be configured according to the type of the second transmission at the resource conflict.

[0329] If the second transmission at the resource conflict location is a transmission of a specified type, the priority of the second transmission is configured to be higher than the priority of the first transmission;

[0330] If the second transmission at the resource conflict is not a transmission of the specified type, the priority of the second transmission is configured to be lower than the priority of the first transmission.

[0331] In some embodiments, the specified type may include a common signal and / or a common message. For example, a typical common signal may include a cell-level reference signal and / or a user equipment (UE) group-level reference signal.

The system information may include, but is not limited to, a master information block (MIB) and / or a system information block (SIB). Exemplarily, the broadcast information may also include some broadcast service data, etc.

[0332] The priority of the first transmission is lower than the priority of the common signal in the second transmission; and / or,

[0333] The priority of the first transmission is lower than the priority of the system information in the second transmission; and / or,

[0334] The priority of the first transmission is lower than the priority of the paging message in the second transmission; and / or,

[0337] In some embodiments, the random access comprises a random access request.

[0338] The common signal includes at least: a synchronization signal broadcast block SSB.

[0339] In some embodiments, if the first information indicates that the first device supports simultaneous execution of the first transmission and the second transmission, then the priority of the first transmission and / or the second transmission may not be configured.

[0344] In some embodiments, the priority information includes first priority information and / or second priority information.

[0345] The first priority information indicates a priority of the first transmission. The second priority information indicates a priority of the second transmission.

[0346] In some embodiments, the network device sends the priority information to the first terminal in the first configuration and / or the second configuration. For example, the first priority information is carried in the first configuration, and the second priority information is carried in the second configuration.

[0347] In some embodiments, the network device sends the priority information to the first terminal using a downlink message different from the downlink message carrying the first configuration and / or the second configuration.

[0348] In some embodiments, an RRC message, a MAC message, or a DCI is sent containing the priority information.

[0349] In some embodiments, the priority of the first transmission and / or the second transmission may be determined by a protocol agreement or according to a preset method. In this case, S2102 and S2103 may be optional steps. For another example, if the first terminal supports simultaneous execution of the first transmission and the second transmission, the priority of the first transmission and / or the second transmission may not be required, and steps S2102 and S2103 may also be omitted.

[0350] In some embodiments, the priority is configured by the network device.

[0351] In other embodiments, the priority is determined by protocol.

[0352] In some embodiments, the first terminal supports simultaneous first and second transmissions, and the first and second resources have a guard interval in the frequency domain. In this case, the network device considers the introduction of the guard interval when configuring the first and second configurations, so that the first and second resources have a certain frequency interval in the frequency domain at the overlapping position in the time domain.

[0353] S3104: The receiving first terminal performs a second transmission according to the priority information.

[0354] In some embodiments, it is determined, based on the priority information, that the second transmission is performed at a location where resources conflict between the first resource and the second resource.

[0355] Exemplarily, the priority information indicates that the priority of the first transmission is lower than the priority of the second transmission, and the second transmission is performed at the location of resource conflict.

[0356] In some embodiments, performing the second transmission may include, but is not limited to, performing UL transmission and / or performing DL transmission.

[0357] Exemplarily, based on the priority information, common signals and / or common information are sent at resource conflicts. Exemplarily, the common signals may include, but are not limited to, cell-level signals and / or UE group-level signals. For example, the common signals may include, but are not limited to, SSBs and / or paging messages. The common information may include, but is not limited to, MIBs and / or SIBs.

[0358] Exemplarily, random access of the first terminal is prioritized at the resource conflict location based on the priority information. For example, based on the priority information, message A, message 1, and / or message 3 sent by the first terminal are preferentially received, and based on the priority information, message B, message 2, and / or message 4 are preferentially sent to the first terminal.

[0359] S3105: Receive the first information.

[0360] In some embodiments, first information sent by a first terminal is received.

[0361] In some embodiments, first information sent by a first terminal when the first terminal switches from a first state to a second state is received.

[0362] In some embodiments, first information sent by the first terminal after the first terminal switches from the first state to the second state is received.

[0363] In some embodiments, the first information is information used by the network device to determine the first transmission to be performed by the first terminal.

[0364] In some embodiments, the first information includes at least one of the following:

[0365] whether the first terminal has a first transmission to be performed;

[0366] A configuration of a first transmission to be performed by the first terminal.

[0367] It is worth noting that: for the relevant content of the first information, please refer to the relevant description of the embodiment S2106 corresponding to Figure 2A.

[0368] S3106: Send the second information.

[0369] In some embodiments, the network device sends the second information to the first terminal.

[0370] In some embodiments, the network device sends the second information to the first terminal when the first terminal switches from the first state to the second state.

[0371] In some embodiments, the network device sends the second information to the first terminal after the first terminal switches from the first state to the second state.

[0372] In some embodiments, the second information is used to indicate whether the first terminal continues to perform the pending first transmission.

[0373] It is worth noting that the optional implementation of S3106 can refer to the optional implementation of Figure S2106.

[0374] It is worth noting that steps S3102 to S3103 are optional. For example, if the first terminal supports simultaneous execution of the first transmission and the second transmission, the network device does not need to configure priority information for the first terminal. For another example, if there is no resource conflict between the first resource corresponding to the first configuration and the second resource corresponding to the second configuration, there is no need to configure priority information for the first terminal. Similarly, steps S2102 to S2103 are optional.

[0375] Steps S3101 to S3103 are optional. For example, if the priority information is agreed upon by a protocol, the network device does not need to configure the priority based on the first transmission and the second transmission. For another example, if there is no resource conflict between the first resource corresponding to the first configuration and the second resource corresponding to the second configuration, there is no need to configure priority information for the first terminal. Similarly, steps S2101 to S2103 are optional.

[0376] S3105 to S3106 are optional steps. For example, when the first terminal does not perform random access-related transmission, S3105 and S3106 do not need to be performed. For another example, reporting the first information can also be an optional step. When the first terminal does not perform cell reselection, that is, the first transmission of the first terminal is still configured in the current cell, the first terminal does not need to report the first information. In this case, the network device will also know whether the first terminal has a first transmission to be performed. Therefore, S3105 and S3106 are both optional steps.

[0377] As shown in FIG3B , an embodiment of the present disclosure provides a wireless communication method, which is performed by a network device and may include:

[0378] S3201: Obtain capability information of network devices.

[0381] In some embodiments, the first transmission and the second transmission share the same frequency band (eg, the first frequency band), and the network device obtains capability information of the first device.

[0382] For example, the first frequency band may be any frequency band in various frequency ranges, for example, the first frequency band belongs to frequency range 1 (FR1) and / or frequency range 2 (FR2) or other frequency ranges.

[0383] In some embodiments, the first transmission includes a continuous wave (CW) transmission by the network device to the second terminal and a backscattered BS reception. For example, the second terminal may be the aforementioned ambient IoT device. For example, the second terminal may be any of the types of devices shown in FIG. 1H .

[0386] In some embodiments, the first transmission and the second transmission share the same frequency band (eg, the first frequency band), and the priority of the first transmission and / or the priority of the second transmission are configured.

[0387] In some embodiments, the network device configures the priority of the first transmission and / or the priority of the second transmission according to the first configuration and / or the second configuration.

[0388] In some embodiments, the first configuration is used to configure a first transmission. Exemplarily, the first configuration is used for the network device to perform the first transmission.

[0396] In some embodiments, when configuring the first resource and / or the second resource, the network device determines that there is a resource conflict between the first resource and the second resource, and then the network device configures the priority of the first transmission and / or the priority of the second transmission according to the first information.

[0397] Exemplarily, when configuring the first resource and / or the second resource, the network device determines that there is a resource conflict between the first resource and the second resource and the first information indicates that the first terminal does not support simultaneous execution of the first transmission and the second transmission, then configures the priority of the first transmission and / or the priority of the second transmission.

[0398] For example, if the first transmission for which resources have been configured is not configured with a priority and the priority of the second transmission to be configured is higher than the priority of the first transmission, the priority of the first transmission can be configured and the priority of the second transmission can be configured, and the priority of the second transmission can be configured to be higher than the priority of the first transmission.

[0399] For another example, if a first transmission for which resources have been configured is not configured with a priority and a second transmission to be configured has a higher priority than the first transmission, the priority of the second transmission can be configured and set to any priority higher than the lowest priority. For example, any priority higher than the lowest priority can be the highest priority. In this case, if the network device does not receive the priority of the first transmission, it can default to the lowest priority for the first transmission at the corresponding location.

[0400] For another example, in some embodiments, if the first resource and the second resource have a resource conflict and the first device does not support simultaneous execution of the first transmission and the second transmission, the priority of the first transmission and / or the priority of the second transmission can be configured according to the type of the second transmission at the resource conflict.

The common message may include: broadcast information and / or multicast information of the cell. The broadcast information may include, but is not limited to, system information. The system information may include, but is not limited to, a master information block (MIB) and / or a system information block (SIB). Exemplarily, the broadcast information may also include some broadcast service data, etc.

[0405] The priority of the first transmission is lower than the priority of the common signal in the second transmission; and / or,

[0406] The priority of the first transmission is lower than the priority of the system information in the second transmission; and / or,

[0407] The priority of the first transmission is lower than the priority of the paging message in the second transmission; and / or,

[0432] S4102: Receive priority information.

[0433] In some embodiments, the priority information may include: priority information indicating a first transmission priority and / or priority information indicating a second transmission priority.

[0434] In some embodiments, the priority information may be carried in any downlink message provided by the network device. For example, the downlink message may include but is not limited to an RRC message, a MAC signaling, and / or a DCI.

[0435] In some embodiments, the priority information is carried in the first configuration and / or the priority information is carried in the second configuration.

[0436] In some embodiments, the first configuration is used to configure a first transmission. Exemplarily, the first configuration is used for a first device to perform the first transmission.

[0437] In some embodiments, the first configuration is at least used to configure a first resource. The first resource may be a time-frequency domain resource for the first transmission.

[0438] In some embodiments, the second configuration is used to configure the second transmission. Exemplarily, the second configuration is used for the first device to perform the second transmission.

[0439] In some embodiments, the second configuration is at least used to configure a second resource. The second resource may be a time-frequency domain resource of the first transmission.

[0440] In some embodiments, the first terminal supports the execution of the first transmission and the second transmission at the same time, and the network device provides the first resource and the second resource which can overlap in the time domain, but in order to ensure the transmission quality, the first resource and the second resource have a protection interval in the frequency domain.

[0441] S4103: Perform the first transmission and / or the second transmission according to the priority indicated by the priority information.

[0442] In some embodiments, at a resource conflict between the first resource and the second resource, the first transmission or the second transmission is performed according to priority.

[0443] In some embodiments, where resources of the first resource and the second resource do not conflict, the first transmission is performed on the first resource according to the first configuration, and / or the second transmission is performed on the second resource according to the second configuration.

[0444] In some embodiments, the first transmission and the second transmission share a first frequency band, there is a resource conflict between the first resource of the first transmission and the second resource of the second transmission, and the second transmission is a random access transmission. The random access transmission is performed according to the priority, and the random access transmission is used to enable the first terminal to switch from the first state to the second state; the first state includes the radio resource control RRC idle state and / or the RRC inactive state; the second state includes the RRC connected state.

[0445] In some embodiments, the priority information herein may include first priority information and / or second priority information, wherein the first priority information indicates the priority of the first transmission, and the second priority information indicates the priority of the second transmission.

[0446] S4104: Send the first message.

[0450] In some embodiments, the first device is a first terminal and after the first terminal switches from a first state to a second state, first information is sent to a network device based on whether the first terminal has a first transmission to be executed; the first information is used by the network device to determine information about the first transmission to be executed by the first terminal.

[0451] S4105: Receive the second information.

[0452] It is worth noting that: the specific implementation of S4105 can be found in S2105 corresponding to the Shihao Li in Figure 2A.

[0453] In some embodiments, the second information is used to indicate whether the first terminal continues to perform the pending first transmission.

[0454] It is worth noting that: the optional implementation manner of S4103 can refer to the steps related to the corresponding embodiments of Figure 2A and / or Figure 2B.

[0455] In some embodiments, steps S4101 and S4102 may be optional. For example, if the first terminal supports simultaneous execution of the first transmission and the second transmission, then step S4102 is optional. For another example, if the priority information is determined by a protocol rather than by a network device configuration, then both steps S4101 and S4102 are optional.

[0456] In some embodiments, S4104 and S4105 are optional steps. For example, if the first terminal does not perform random access related transmission, S4104 and S4105 can be omitted.

[0457] In some embodiments, the first terminal supports simultaneous execution of the first transmission and the second transmission. The first terminal may also ignore the priority information or not obtain the priority information, and directly execute the first transmission according to the first configuration and / or execute the second transmission according to the second configuration.

[0458] In the Radio Frequency Identification (RFID) system, how to use the in-band spectrum resources in the existing NR communication system to build an ambient IoT network. At the same time, avoid the coexistence interference of ambient IoT communication and NR communication, and reasonably allocate the resources of ambient IoT communication and NR communication. For example, the ambient IoT resources of ambient IoT communication can be deployed on the in-band spectrum of the NR base station.

[0459] If ambient IoT resources are deployed on the NR spectrum of an NR base station, DL transmission and CW transmission are performed by one node, for example, both DL transmission and CW transmission are performed by the same base station. In other embodiments, DL transmission and CW transmission are performed by different nodes, for example, DL transmission is performed by the base station and CW transmission is performed by the terminal.

[0460] If DL transmission and CW transmission are performed by the same node, then CW transmission can be considered as part of DL transmission. In this case, CW transmission can be considered as one of the excitation signal corresponding to CW transmission and DL transmission by default.

[0461] Exemplarily, DL transmission may also be understood as DL message, DL signal and / or DL ​​information, etc.

[0462] Exemplarily, DL transmission may also be understood as DL message, DL signal and / or DL ​​information, etc.

[0463] Scenario 1: As shown in Figure 5A, ambient IoT resources for CW transmission and backscatter BS reception are both deployed on the DL spectrum of the NR spectrum.

[0464] Ambient IoT resources and NR resources can be time-division multiplexed and / or frequency-division multiplexed. Ambient IoT resources herein can be used for any transmission related to ambient IoT devices. For example, the ambient IoT resources can be used for CW transmission and / or BS reception. NR resources are used for transmission on the Uu port. Exemplarily, the ambient IoT resource is a type of the aforementioned first resource. The NR resource is a type of the aforementioned second resource.

[0465] First, the NR base station allocates ambient IoT resources, as shown in Figure 5E:

[0466] Time Division Multiplexing: Configure a period, duration, and / or time domain offset; optionally, for example, the time domain offset is set to 0. This duration can be used to determine a time window. Ambient IoT resources are configured within this time window. If time division multiplexing is used as shown in Figure 5E(A), the ambient IoT resources and NR resources are configured within different time ranges of the DL spectrum and / or UL spectrum.

[0467] Frequency Division Multiplexing (FDM): A spectrum range with a similar BWP is configured, which can be used for transmission of ambient IoT devices. If FDM is used, as shown in Figure 5E(B), the ambient IoT resources and NR resources are configured in different sub-bands of the DL spectrum and / or UL spectrum.

[0468] Simultaneous time division multiplexing and frequency division multiplexing: Configure a spectrum range similar to the BWP, and configure a period, duration, and / or time domain offset. If frequency division multiplexing is used as shown in Figure 5E(C), ambient IoT resources and NR resources are configured in different sub-bands of the DL spectrum and / or UL spectrum.

[0469] By giving the Uu port's SSB transmission a higher priority than ambient IOT-related transmissions, it is possible to ensure that the SSB transmission is not affected by ambient IOT transmissions.

[0470] In some embodiments, ambient IOT-related transmissions may also be referred to as ambient IOT operations.

[0471] If a conflict occurs between ambient IoT operation and SSB, paging and / or SIB reception in NR, the network side configures the priority of ambient IoT operation and reception of public signals in NR, so that the terminal can resolve the above conflict according to the priority. Exemplarily, the network device can configure a priority for each public signal and / or public information. In this way, the priorities of different public signals and / or public information can be the same or different. As another example, different public signals can share the same priority, or different public information can share the same priority. For example, public signals and public information can share the same priority.

[0472] If a terminal cannot support both BS and DL reception simultaneously, it must notify the base station in advance that it cannot notify network devices of its own reception capabilities. The base station will then configure ambient IoT resources to avoid time-domain overlap between BS and DL reception resources. Alternatively, if BS and DL reception resources overlap in time, the base station will configure corresponding priorities to facilitate resource conflict resolution based on priority. For example, low-priority transmissions will be discarded, meaning that the terminal will execute high-priority transmissions and ignore low-priority transmissions.

[0473] If the terminal cannot support CW transmission and DL reception at the same time, the base station will avoid time domain overlap of BS reception and DL reception resources when configuring ambient IoT resources. Alternatively, if the CW transmission and DL reception resources overlap in time domain, the base station will configure corresponding priorities to facilitate the terminal to resolve resource conflicts based on priority.

[0474] If the terminal supports simultaneous CW transmission and DL reception, in order to ensure communication quality, an isolation band may be configured between CW transmission and DL reception, or may not be configured.

[0475] The isolation band here may be a type of the aforementioned guard interval.

[0476] Scenario 2: As shown in Figure 5B, the ambient IoT resources for CW transmission and backscatter BS reception are deployed in the UL spectrum of the NR spectrum.

[0477] Time Division Multiplexing: Configure a period, duration, and / or time domain offset; optionally, for example, the time domain offset is set to 0. This duration can be used to determine a time window. Ambient IoT resources are configured within this time window. If time division multiplexing is used as shown in Figure 5E(A), the ambient IoT resources and NR resources are configured within different time ranges of the DL spectrum and / or UL spectrum.

[0478] Frequency Division Multiplexing (FDM): A spectrum range with a similar BWP is configured, which can be used for transmission of ambient IoT devices. If FDM is used, as shown in Figure 5E(B), the ambient IoT resources and NR resources are configured in different sub-bands of the DL spectrum and / or UL spectrum.

[0479] Simultaneous time division multiplexing and frequency division multiplexing: Configure a spectrum range similar to the BWP, and configure a period, duration, and / or time domain offset. If frequency division multiplexing is used as shown in Figure 5E(C), ambient IoT resources and NR resources are configured in different sub-bands of the DL spectrum and / or UL spectrum.

[0480] The NR base station configures the terminal's resource allocation for executing ambient IoT as follows:

[0481] If an ambient IOT operation, such as BS reception, conflicts with SSB, paging, and / or SIB reception in NR, the network side configures the priority of the ambient IOT operation and the reception of the common signal in NR. In this way, the terminal can resolve the above conflict according to the priority. Exemplarily, the network device can configure a priority for each common signal and / or common information. In this way, the priorities of different common signals and / or common information can be the same or different. In another exemplary embodiment, different common signals can share the same priority, or different common information can share the same priority. For example, common signals and common information can share the same priority.

[0482] If a terminal cannot support both BS reception and UL transmission simultaneously, it must notify the base station in advance of its inability to notify network devices of its own transceiver capabilities. The base station will then configure ambient IoT resources to avoid BS reception and UL transmission being configured on the same time domain resources. Alternatively, if BS reception and UL transmission are configured on the same time domain resources, it will prioritize BS reception and UL transmission. This allows the terminal to determine whether to perform BS reception or UL transmission based on priority in the event of resource conflicts. For example, low-priority transmissions will be discarded, meaning the terminal will execute high-priority transmissions and ignore low-priority transmissions.

[0483] Scenario 3: As shown in Figures 5C and 5D, ambient IoT resources for CW transmission and BS reception are deployed in spectrum in different transmission directions of the NR spectrum. For example, CW transmission is deployed on the UL spectrum and BS reception is deployed on the DL spectrum, or CW transmission is deployed on the DL spectrum and BS reception is deployed on the UL spectrum. In this case, the CW transmission, BS reception, and various transmissions on the Uu interface can be referred to any of the embodiments of Scenario 1 and / or Scenario 2.

[0484] Regardless of the scenario, if the terminal needs to initiate a RACH process due to NR services to enable the terminal to enter the RRC connected state, and the ambient IOT operation is still in progress, the following operations can be performed:

[0485] Option 1: If the terminal needs to initiate the RACH process of the Uu port, the terminal suspends the ambient IOT operation until the random access process is completed, or the terminal notifies the network side of the operation instructions about the ambient IOT operation and / or the configuration parameters related to the ambient IOT after entering the RRC connection state, until the network side displays the configuration instruction for the terminal to continue the ambient IOT operation in the RRC connection state, otherwise the ambient IOT operation is not performed.

[0486] Option 2: If the terminal needs to initiate the RACH process of the Uu port, the ambient IOT operation is not suspended. However, if the sending and receiving of Msg1, Msg2, Msg3, Msg4, MsgA and / or MsgB conflict with the ambient IOT operation and cannot be performed at the same time, the RACH operation has a higher priority and the corresponding ambient IOT operation is discarded, such as discarding CW sending and / or BS receiving.
