[0088] As shown in Figure 1A, the communication system 100 includes a first device 101 and a second device 102.

[0089] In some embodiments, the first device 101 may be an A-IoT device or a 6G IoT device, but is not limited thereto. An A-IoT device may also be referred to as an A-IoT device, an A-IoT terminal, an A-IoT tag, etc.

[0090] In some embodiments, the second device 102 may be a network device or a terminal. The second device 102 may serve as a base station, an intermediate node, or a node other than an intermediate node in the Internet of Things.

[0091] In some embodiments, the second device 102 can control the CW node to send CW signals, and the first device 101 can reflect the CW signals to form a reflected wave, which is then sent to the second device 102. The second device 102 and the CW node can be the same device or different devices.

[0092] In some embodiments, the terminal may be a user equipment (UE), including, but not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0100] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0101] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0102] In the A-IoT Internet of Things, the number of A-IoT terminals (such as A-IoT UE, A-IoT device, and A-IoT tag) that can be accessed in the network is large, and they have simple structure, low hardware and maintenance costs, low power consumption, and can usually not need to replace batteries for a long time.

[0103] IoT technology can be applied to scenarios involving large-scale inventory management, such as A-IoT devices reporting Electronic Product Codes (EPCs) to the network / intermediate node X / UE. It can also be applied to sensing scenarios such as smart homes and environmental monitoring, where A-IoT devices report data when certain trigger conditions are met. IoT technology can also be used in location-based scenarios, such as locating items or pinpointing locations within a shopping mall. Furthermore, IoT technology can be used in command-based scenarios, such as responding to commands sent by network devices.

[0104] In some embodiments, the A-IoT device has a peak power of 1 μW, energy storage capability, an initial sampling frequency offset (SFO) of up to 10X ppm, and neither downlink (DL) nor uplink (UL) amplification is present in the device. The device's UL transmission is backscattered on an externally provided carrier.

[0105] In some embodiments, the peak power of the A-IoT device is less than or equal to several hundred μW, has energy storage capabilities, and an SFO of up to 10Xppm, allowing for DL ​​and / or UL amplification within the device. The UL transmission of the device can be generated internally or backscattered on an externally provided carrier.

[0106] In some embodiments, A-IoT devices can be categorized into the following types:

[0107] Device 1: Peak power consumption is 1μW, it can store energy, it cannot independently generate / amplify signals, it uses a backscatter working mode, and it does not have the ability to amplify DL and / or UL signals.

[0108] Device 2a: Peak power consumption is several hundred μW, it has energy storage capability, it cannot generate signals independently, and it uses a backscattering operating mode; the stored energy can be used for DL ​​and / or UL signal amplification.

[0109] Device 2b: Peak power consumption is several hundred μW, with energy storage capabilities, and it can independently generate signals, such as an active signal transmission radio frequency (RF) module. Alternatively, it can simultaneously possess the ability to actively transmit information and backscatter.

[0110] Furthermore, Device 1 and Device 2a, which can only operate using backscattering, cannot actively transmit signals. When they need to transmit information, they require an external source to provide a continuous electromagnetic wave (CW) for backscattering. The CW is generally of constant amplitude. A CW node can be a single node or a network / intermediate node (e.g., UE) communicating with the device. The A-IoT device reflects the received CW, loading the signaling / data to be transmitted onto the reflected wave and sending it out. The reflected wave and the CW are at the same frequency or have a certain frequency offset. Simultaneously, the CW also serves to power the A-IoT device. For example, when a Type 1 device receives a wireless signal CW, it activates its internal receiving and processing module to encode and modulate the signaling / data that the A-IoT device needs to upload.

[0111] In some embodiments, A-IoT network devices include networks, terminals, intermediate nodes, auxiliary nodes, etc. Intermediate nodes can be relays, integrated access and backhaul (IAB) nodes, terminals, or repeaters.

[0112] Figure 1B is a schematic diagram of one deployment structure according to an embodiment of the present disclosure. Figure 1C is a schematic diagram of another deployment structure according to an embodiment of the present disclosure.

[0113] In some embodiments, A-IoT devices can support two deployment structures: Topology 1 as shown in Figure 1B and Topology 2 as shown in Figure 1C.

[0114] In Topology 1, A-IoT devices and networks (e.g., base stations, BS) directly receive and transmit DL and UL data.

[0115] In Topology 2, A-IoT devices and networks (e.g., BS) indirectly receive and transmit DL and UL data through intermediate nodes; the intermediate nodes are used for data forwarding, and data transmission between the intermediate nodes and the BS is carried out through the Uu interface.

[0116] In some embodiments of a passive Internet of Things (IoT) system, the data sent by the terminal may be of the following types:

[0117] Type 1: Based on network demand report data, such as inventory, i.e. DO-DTT service. DO-DTT refers to a service that is initiated by the device but needs to be triggered by the reader (Device-originated–device-terminated triggered).

[0118] Type 2: Based on environmental IoT triggering, such as when the temperature of a sensor exceeds a configured threshold, i.e., DO service, which refers to device-originated service;

[0119] Type 3: Periodic Data Reporting: Based on the self-triggered environmental IoT, periodic environmental IoT data reporting is achieved, namely DO-A service, which refers to device-originated-autonomous service;

[0120] Type 4: The network side sends a command, and the device performs corresponding operations based on the command. This is called DT service, which refers to the service terminated by the device.

[0121] In 6G A-IoT, further research is needed on application scenarios for sensors and positioning. Sensors refer to devices that can perceive their surroundings and obtain environmental information such as temperature and humidity. This requires support for device-initiated services, i.e., DO-A services. DO-A services typically involve periodic uplink transmissions without requiring network device triggering, thus supporting environmental awareness applications. In positioning scenarios, through information exchange between network devices and terminals, the network device obtains the terminal's location information.

[0122] For the Device2b type devices mentioned above, they internally generate a single-tone carrier wave. These devices do not use small frequency offsets, but only large ones. The devices support large frequency offsets, meaning that the CW (Content Message Wave) and the device-to-reader (D2R) transmission are located on different spectrums. For example, the CW transmission is located on the uplink (UL) spectrum, while the D2R transmission is located on the downlink (DL) spectrum. Furthermore, Frequency Division Multiplexing (FDM) of Device2b type devices can be achieved by directly modulating the internally generated carrier to the required frequency. Therefore, for Device2b type devices, under the large frequency offset method, when devices use FDM for uplink transmission, determining the frequency domain resources of different devices is a technical problem that needs to be solved.

[0123] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a communication method, which includes:

[0124] In step S2101, the second device 102 sends the first information to the first device 101.

[0125] In some embodiments, the first device 101 receives first information sent by the second device 102.

[0126] In some embodiments, the first device can be an A-IoT device or a 6G IoT device, but is not limited thereto. The first device may also be referred to as a device, an A-IoT device, an A-IoT terminal, an A-IoT tag, etc. The second device can be a reader, a network device, or a terminal. The second device can serve as a base station, an intermediate node, or other nodes besides intermediate nodes in the Internet of Things.

[0127] In some embodiments, the first information indicates multiple combinations, each of which consists of a magnification factor and an offset value, and the multiple combinations are used to determine the first magnification factor and the first offset value.

[0128] In some embodiments, the amplification factor is represented by n, and the offset value is represented by offset. The second device can configure multiple combinations of amplification factors and offset values, each combination having a different amplification factor and / or offset value. Different first devices can use different combinations to determine the frequency domain resources used for uplink transmission, thereby ensuring that different first devices use different frequency domain resources.

[0129] In some embodiments, the first device may select a set of multiple combinations as the magnification and offset values ​​used by the first device, and the magnification and offset values ​​determined by the first device may be referred to as the first magnification and the first offset value.

[0130] For example, the set of combinations of n and offset values ​​configured for the second device is {(n=1, offset1), (n=1, offset2), (n=1, offset3)...(n=2, offset4)}. The n value and / or offset value are different in each combination.

[0131] In some embodiments, the second device sends first information to the first device, that is, the second device instructs the first device to a plurality of combinations consisting of n values ​​and offset values.

[0132] In some embodiments, the first information may be configured or pre-configured by the second device to the first device via higher-layer signaling; or indicated to the first device via broadcast information, such as notification to the first device in a broadcast channel or system message; or indicated to the first device by carrying a set of combinations of n and offset values ​​in a paging message or repaging message.

[0133] In some embodiments, step S2101 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0134] In step S2102, the second device 102 sends the second information to the first device 101.

[0135] In some embodiments, the first device 101 receives second information sent by the second device 102.

[0136] In some embodiments, the second information includes a combined index corresponding to the first device.

[0137] In some embodiments, a composite index is used to indicate one of a plurality of combinations, and the composite index refers to the index of a particular combination.

[0138] In some embodiments, the first device determines a first magnification factor and a first offset value based on a combined index, the first magnification factor and the first offset value being used for uplink transmission by the first device.

[0139] In some embodiments, the second information also includes a combined index corresponding to other devices, with different magnification factors and / or offset values ​​corresponding to different devices.

[0140] In some embodiments, "other devices" refers to other first devices different from the current first device. The second device can send second information to multiple first devices, the second information including combined indices corresponding to each of the multiple first devices. After receiving the second information, each first device determines the magnification factor and offset value based on its corresponding combined index.

[0141] In some embodiments, the second device may send second information to the first device. The second information includes a combined index corresponding to different first devices. The combined indexes corresponding to different first devices are different. Each first device can determine the amplification factor and offset value according to its corresponding combined index, thereby ensuring that each first device uses different frequency domain resources.

[0142] For example, the set of combinations of n and offset values ​​indicated by the second device is {(n=1, offset1), (n=1, offset2), (n=1, offset3)...(n=2, offset4)}. Then, the first device 1 can use (n=1, offset1) to determine the frequency domain resources occupied by the uplink transmission, the first device 2 can use (n=1, offset2) to determine the frequency domain resources occupied by the uplink transmission, and so on, and the first device 4 can use (n=2, offset4) to determine the frequency domain resources occupied by the uplink transmission.

[0143] For example, if the set of n-value and offset-value combinations contains M combinations of n-value and offset-value combinations, then the number of second devices for uplink-supported FDM is M.

[0144] In some embodiments, the second information may be downlink reader-to-device (R2D) information, which may be R2D control information, such as an index indicating the n value and offset value in the R2D control information.

[0145] In some embodiments, the second information may be Msg2, a reply from the second device to Msg1 sent by the first device. For example, Msg2 may indicate the index of the n value and the offset value. For instance, if the first device sends Msg1 as RN1, the second device may reply with Msg2 carrying the index of the n value and the offset value, i.e., replying with ACK+RN16+index, where the length of the index is log2(X), and X is the number of combinations of the n value and the offset value.

[0146] In some embodiments, a mapping relationship between the index and the n-value and offset value can be defined. The set of combinations of n-value and offset value is, for example, {(n=1, offset1), (n=1, offset2), (n=1, offset3), (n=2, offset4), (n=2, offset5), (n=2, offset6)}, which has a total of 6 pairs of values. Then, 3 bits can be used to indicate a certain pair of n-value and offset value. The mapping relationship between the index and the n-value and offset value is shown in Table 1.

[0147] Table 1

[0148] In some embodiments, the first device may randomly select a set of amplification factors and offset values ​​from multiple combinations as the first amplification factor and the first offset value, and determine the frequency domain resources for this uplink transmission based on the first amplification factor and the first offset value.

[0149] In some embodiments, the first device may determine the first amplification factor and the first offset value based on the combined index included in the second information sent by the second device, and determine the frequency domain resources for this uplink transmission based on the first amplification factor and the first offset value.

[0150] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0151] In step S2103, the first device 101 determines the frequency domain resources for uplink transmission based on the first frequency point.

[0152] In some embodiments, the first frequency point is the frequency point of the continuous electromagnetic wave CW or the reference frequency point.

[0153] In some embodiments, the first frequency point is the frequency point where CW is located.

[0154] The following explains how to determine the frequency domain resources used for uplink transmission when the first frequency point is the frequency point where CW is located.

[0155] In some embodiments, determining the frequency domain resources for uplink transmission based on a first frequency point includes: determining a first position of the frequency domain resources based on the frequency point where the CW is located, a first amplification factor, and a first offset value; wherein the first position is one of the center position, the lowest position, and the highest position of the frequency domain resources.

[0156] In some embodiments, the frequency point where CW is located can also be referred to as the frequency where CW is located, and the frequency point where CW is located can be represented by f1.

[0157] In some embodiments, the frequency point f1 where CW is located can be multiplied by the first amplification factor n, and the sum of the product and the first offset value can be used as the first position of the frequency domain resource. The first position is one of the center position, the lowest position, and the highest position of the frequency domain resource.

[0158] For example, the center position of the frequency domain resources occupied by uplink transmission can be determined based on f1×n+offset.

[0159] For example, the lowest position of the frequency domain resources occupied by uplink transmission can be determined based on f1×n+offset.

[0160] For example, the highest position of the frequency domain resources occupied by uplink transmission can be determined based on f1×n+offset.

[0161] In this embodiment of the disclosure, the first position of the uplink frequency domain resource is determined based on the frequency point where CW is located, the first amplification factor, and the first offset value, which can ensure that the uplink frequency domain resource is different from the frequency domain resource where CW is located.

[0162] In some embodiments, a first magnification factor and a first offset value are determined from multiple combinations based on a random selection method, and the first magnification factor and the first offset value are used for uplink transmission by the first device.

[0163] In some embodiments, the first device may randomly select a set of amplification factors and offset values ​​from multiple combinations as the first amplification factor and the first offset value, and determine the frequency domain resources for this uplink transmission based on the first amplification factor and the first offset value.

[0164] In some embodiments, the first magnification factor and the first offset value determined by random selection can be used for the first uplink transmission from the first device to the second device, or for subsequent uplink transmissions, such as the second uplink transmission and the third uplink transmission.

[0165] For example, when the first device sends Msg1 to the second device, the first device randomly selects a set of n and offset values ​​from the combinations of n and offset values ​​for this uplink transmission.

[0166] In some embodiments, the first device may determine the first amplification factor and the first offset value based on the combined index included in the second information sent by the second device, and determine the frequency domain resources for this uplink transmission based on the first amplification factor and the first offset value.

[0167] In some embodiments, the uplink information of the first device can be transmitted via both sidesband or by a single sideband.

[0168] In some embodiments, determining the first location of a frequency domain resource includes: determining the first location of a sideband in response to the first device using a single sideband for uplink transmission; or, determining the first locations of two sidebands respectively in response to the first device using double sidebands for uplink transmission.

[0169] In some embodiments, the first device uses a single sideband for uplink transmission, and determines the first position of the sideband based on the frequency point where the CW is located, the first amplification factor, and the first offset value. The first position is one of the center position, the lowest position, and the highest position.

[0170] In some embodiments, the first device uses double-sideband uplink transmission. Based on the frequency of the CW (Central Wing), a first amplification factor, and a first offset value, it determines the first positions of the two sidebands. The first position is one of a center position, a lowest position, or a highest position. The combinations corresponding to the two sidebands are different; that is, the first amplification factors and / or first offset values ​​corresponding to the two sidebands are different, and the first positions corresponding to the two sidebands are different. For example, the first amplification factors of the two sidebands are the same, but the first offset values ​​are different.

[0171] In some embodiments, determining the frequency domain resources for uplink transmission based on the first frequency point further includes: determining the frequency domain resources based on the first location and the bandwidth occupied by uplink transmission.

[0172] In some embodiments, the bandwidth occupied by uplink transmission can be represented by BW, which can be a protocol definition, a pre-configured or configured fixed value of the second device, or an R2D downlink information indication.

[0173] In some embodiments, the center position of the sideband is determined based on the frequency point where the CW is located, the first amplification factor, and the first offset value, and the frequency domain resources are determined based on the center position of the sideband and the bandwidth occupied by the uplink transmission.

[0174] For example, if the first device's D2R is a double-sideband transmission, the first amplification factor corresponding to both sidebands is n, and the first offset values ​​corresponding to the two sidebands are offset1 and offset2 respectively, then the center frequencies of the two sidebands of the first device's D2R transmission are f1×n+offset1 and f1×n+offset2 respectively. The transmission bandwidth occupied by the first device's D2R transmission is BW, then the frequency domain resources occupied by the two sidebands of the first device's uplink D2R transmission are [f1×n+offset1-1 / 2BW, f1×n+offset1+1 / 2BW] and [f1×n+offset2-1 / 2BW, f1×n+offset2+1 / 2BW respectively].

[0175] For example, if the first device's D2R is not a double-sideband transmission, but a single-sideband transmission, and the first amplification factor corresponding to the sideband is n, and the first offset value is offset1, then the center frequency of one sideband of the first device's D2R transmission is f1×n+offset1. The transmission bandwidth occupied by the first device's D2R transmission is BW, then the frequency domain resources occupied by the device's uplink D2R transmission are [f1×n+offset1-1 / 2BW, f1×n+offset1+1 / 2BW].

[0176] In some embodiments, the lowest position of the sideband is determined based on the frequency point where the CW is located, the first amplification factor, and the first offset value, and the frequency domain resources are determined based on the lowest position of the sideband and the bandwidth occupied by the uplink transmission.

[0177] For example, the first device's D2R is a double-sideband transmission. The first amplification factor corresponding to the two sidebands is n, and the first offset values ​​corresponding to the two sidebands are offset1 and offset2, respectively. Then, the lowest frequency points of the two sidebands of the first device's D2R transmission are f1×n+offset1 and f1×n+offset2, respectively. The frequency domain resources occupied by the two sidebands of the first device's uplink D2R transmission are [f1×n+offset1, f1×n+offset1+BW] and [f1×n+offset2, f1×n+offset2+BW], respectively.

[0178] For example, if the first device's D2R is not a double-sideband transmission, but a single-sideband transmission, and the first amplification factor corresponding to the sideband is n, and the first offset value is offset1, then the lowest frequency point of one sideband of the first device's D2R transmission is f1×n+offset1. The transmission bandwidth occupied by the first device's D2R transmission is BW, then the frequency domain resources occupied by the device's uplink D2R transmission are [f1×n+offset1, f1×n+offset1+BW].

[0179] In some embodiments, the highest position of the sideband is determined based on the frequency point where the CW is located, the first amplification factor, and the first offset value, and the frequency domain resources are determined based on the highest position of the sideband and the bandwidth occupied by the uplink transmission.

[0180] For example, the first device's D2R is a double-sideband transmission. The first amplification factor corresponding to the two sidebands is n, and the first offset values ​​corresponding to the two sidebands are offset1 and offset2, respectively. Then, the highest frequency points of the two sidebands transmitted by the first device's D2R are f1×n+offset1 and f1×n+offset2, respectively. The frequency domain resources occupied by the two sidebands transmitted by the first device's uplink D2R are [f1×n+offset1-BW, f1×n+offset1] and [f1×n+offset2-BW, f1×n+offset2], respectively.

[0181] For example, if the first device's D2R is not a double-sideband transmission, but a single-sideband transmission, and the first amplification factor corresponding to the sideband is n, and the first offset value is offset1, then the highest frequency point of one sideband of the first device's D2R transmission is f1×n+offset1. The transmission bandwidth occupied by the first device's D2R transmission is BW, then the frequency domain resources occupied by the device's uplink D2R transmission are [f1×n+offset1-BW, f1×n+offset1].

[0182] In step S2104, the first device 101 sends uplink information to the second device 102.

[0183] In some embodiments, the second device 102 receives uplink information sent by the first device 101.

[0184] In some embodiments, the first device may send uplink information to the second device based on determined frequency domain resources.

[0185] In some embodiments, different first devices may use different combinations to determine the frequency domain resources used for uplink transmission, thereby ensuring that different first devices use different frequency domain resources.

[0186] In this embodiment of the disclosure, the first position of the uplink frequency domain resource is determined based on the frequency point where CW is located, the first amplification factor, and the first offset value, which can ensure that the uplink frequency domain resource is different from the frequency domain resource where CW is located.

[0187] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2104. For example, step S2103 may be implemented as a standalone embodiment, step S2101+S2103 may be implemented as a standalone embodiment, S2101+S2102+S2103 may be implemented as a standalone embodiment, and step S2104 may be implemented as a standalone embodiment, but is not limited thereto.

[0188] In some embodiments, step S2101 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0189] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0190] In some embodiments, step S2104 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0191] In some embodiments, other alternative implementations may be described before or after the specification corresponding to FIG2A.

[0192] Figure 2B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2B, the embodiments of the present disclosure relate to a communication method, which includes:

[0193] In step S2201, the second device 102 sends third information to the first device 101.

[0194] In some embodiments, the first device 101 receives third information sent by the second device 102.

[0195] In some embodiments, the first device can be an A-IoT device or a 6G IoT device, but is not limited thereto. The first device may also be referred to as a device, an A-IoT device, an A-IoT terminal, an A-IoT tag, etc. The second device can be a reader, a network device, or a terminal. The second device can serve as a base station, an intermediate node, or other nodes besides intermediate nodes in the Internet of Things.

[0196] In some embodiments, the third information indicates a second offset value corresponding to the first device.

[0197] In some embodiments, the second offset value is used to determine the frequency domain resources used by the first device for uplink transmission.

[0198] In some embodiments, the second offset value is an offset value of the first position of the frequency domain resource used for uplink transmission relative to a reference frequency point, and the first position may be one of the middle position, the lowest position, and the highest position of the frequency domain resource used for uplink transmission.

[0199] In some embodiments, the second device may send third information to the first device, the third information including a second offset value corresponding to the first device, and the first device may determine the frequency domain resources for uplink transmission based on the second offset value and a reference frequency point.

[0200] In some embodiments, the third information also includes offset values ​​corresponding to other devices, and the offset values ​​corresponding to different devices are different.

[0201] In some embodiments, "other devices" refers to other first devices different from the current first device. The second device can send third information to multiple first devices, the third information including second offset values ​​corresponding to each of the multiple first devices. After receiving the third information, each first device determines the frequency domain resources for uplink transmission based on its corresponding second offset value.

[0202] In some embodiments, the second device may send third information to the first device. The third information includes offset values ​​corresponding to different first devices. The offset values ​​corresponding to different first devices are different. Each first device can determine the frequency domain resources used for uplink transmission based on its corresponding offset value, thereby ensuring that the frequency domain resources used by each first device are different.

[0203] In some embodiments, the third information may be pre-configured or configured by the second device to the first device, or indicated by the second device to the first device via R2D control signaling.

[0204] In some embodiments, step S2201 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0205] In step S2202, the second device 102 sends the fourth information to the first device 101.

[0206] In some embodiments, the first device 101 receives fourth information sent by the second device 102.

[0207] In some embodiments, the fourth information indicates the spectrum where the reference frequency point is located.

[0208] In some embodiments, the spectrum of the reference frequency point and the spectrum of the CW frequency point are different. For example, the spectrum of the CW frequency point is the uplink spectrum, and the spectrum of the reference frequency point is the downlink spectrum.

[0209] In some embodiments, if the frequency point of the CW is located in the uplink spectrum, then the reference frequency point is defined in the downlink spectrum; the second control CW transmission, the second device knows the spectrum where the CW is located, then the second device can indicate the spectrum where the reference frequency point is located to the first device through higher layer signaling, for example, using 1 bit to indicate that the current reference frequency point is defined in the downlink spectrum, for example, the bit value is 0 to indicate that the current reference frequency point is defined in the downlink spectrum.

[0210] In some embodiments, if the frequency point where the CW is located is on the downlink spectrum, then the reference frequency point is defined on the uplink spectrum; the second control CW transmission, the second device knows the spectrum where the CW is located, then the second device can indicate the spectrum where the reference frequency point is located to the first device through higher layer signaling, for example, using 1 bit to indicate that the current reference frequency point is defined on the uplink spectrum, for example, the bit value is 1 to indicate that the current reference frequency point is defined on the uplink spectrum.

[0211] In some embodiments, the first device may determine the spectrum where the reference frequency point is located based on the fourth information.

[0212] In some embodiments, step S2202 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0213] In step S2203, the first device 101 determines the frequency domain resources for uplink transmission based on the first frequency point.

[0214] In some embodiments, the first frequency point is the frequency point of the continuous electromagnetic wave CW or the reference frequency point.

[0215] In some embodiments, the first frequency point is a reference frequency point, and the reference frequency point and the frequency point where CW is located are in different frequencies.

[0216] The following explains how to determine the frequency domain resources used for uplink transmission when the first frequency point is the reference frequency point.

[0217] In some embodiments, determining the frequency domain resources for uplink transmission based on a first frequency point includes: determining a first position of the frequency domain resources based on a reference frequency point and a second offset value; wherein the first position is one of the center position, the lowest position, and the highest position of the frequency domain resources.

[0218] In some embodiments, the reference frequency point may also be referred to as the anchor frequency point, and the reference frequency point can be used with f A express.

[0219] In some embodiments, the reference frequency point f A It is not the frequency point where CW is located, but a common reference point for resources in a system.

[0220] In some embodiments, the reference frequency point f A Since the CW frequency point is located on a different spectrum, a reference frequency point f can be defined on both the uplink and downlink spectrums. A .

[0221] In some embodiments, the reference frequency point f for the uplink and downlink spectrum AThe value can be configured or pre-configured to the first device by the second device through higher-layer signaling; or indicated to the first device through broadcast information, such as notification to the first device in a broadcast channel or system message; or indicated in a paging message or repaging message; or as specified by the protocol, and the first and second devices are known to each other.

[0222] In some embodiments, the sum of the reference frequency point and the second offset value can be used as the first position of the frequency domain resource, where the first position is one of the center position, the lowest position, or the highest position of the frequency domain resource.

[0223] For example, based on f A +offset determines the center position of the frequency domain resources occupied by the uplink transmission.

[0224] For example, based on f A +offset determines the lowest position of the frequency domain resources occupied by the uplink transmission.

[0225] For example, based on f A +offset determines the highest position of the frequency domain resources occupied by the uplink transmission.

[0226] In this embodiment of the disclosure, the first position of the uplink transmitted frequency domain resource is determined based on the reference frequency point and the second offset value, which can ensure that the uplink transmitted frequency domain resource is different from the frequency domain resource where CW is located.

[0227] In this embodiment of the disclosure, different first devices can use different second offset values ​​to determine the frequency domain resources used for uplink transmission, thereby ensuring that different first devices use different frequency domain resources.

[0228] In some embodiments, the uplink information of the first device can be transmitted via both sidesband or by a single sideband.

[0229] In some embodiments, determining the first location of a frequency domain resource includes: determining the first location of a sideband in response to the first device using a single sideband for uplink transmission; or, determining the first locations of two sidebands respectively in response to the first device using double sidebands for uplink transmission.

[0230] In some embodiments, the first device uses a single sideband for uplink transmission and determines a first position of the sideband based on a reference frequency and a second offset value. The first position is one of a center position, a lowest position, or a highest position.

[0231] In some embodiments, the first device uses double-sideband uplink transmission. Based on a reference frequency and a second offset value, it determines the first position of the two sidebands, where the first position is one of a center position, a lowest position, or a highest position. The combinations corresponding to the two sidebands are different; that is, the second offset values ​​and first positions corresponding to the two sidebands are different.

[0232] In some embodiments, determining the frequency domain resources for uplink transmission based on the first frequency point further includes: determining the frequency domain resources based on the first location and the bandwidth occupied by uplink transmission.

[0233] In some embodiments, the bandwidth occupied by uplink transmission can be represented by BW, which can be a protocol definition, a pre-configured or configured fixed value of the second device, or an R2D downlink information indication.

[0234] In some embodiments, the center position of the sideband is determined based on the reference frequency and the second offset value, and the frequency domain resources are determined based on the center position of the sideband and the bandwidth occupied by the uplink transmission.

[0235] For example, if the first device's D2R is a double-sideband transmission, and the second offset values ​​corresponding to the two sidebands are offset1 and offset2 respectively, then the center frequencies of the two sidebands in this D2R transmission of the first device are f1 and offset2 respectively. A +offset1 and f A +offset2, the transmission bandwidth occupied by the D2R transmission of the first device is BW, then the frequency domain resources occupied by the two sidebands of the uplink D2R transmission of the first device are [f A +offset1-1 / 2BW,f A +offset1+1 / 2BW] and [f A +offset2-1 / 2BW,f A +offset2+1 / 2BW).

[0236] For example, if the first device's D2R is not a double-sideband transmission, but rather a single-sideband transmission, and the second offset value is offset1, then the center frequency of one sideband transmitted by the first device in this D2R transmission is f. A +offset1, the transmit bandwidth occupied by the D2R transmission of the first device is BW, then the frequency domain resources occupied by the device's uplink D2R transmission are [f A +offset1-1 / 2BW,f A +offset1+1 / 2BW).

[0237] In some embodiments, the lowest position of the sideband is determined based on a reference frequency point and a second offset value, and frequency domain resources are determined based on the lowest position of the sideband and the bandwidth occupied by uplink transmission.

[0238] For example, if the first device uses dual-sideband D2R transmission, and the second offset values ​​corresponding to the two sidebands are offset1 and offset2 respectively, then the lowest frequency points of the two sidebands in this D2R transmission of the first device are f1 and offset2 respectively. A +offset1 and f A +offset2, the frequency domain resources occupied by the two sidebands transmitted by the first device in the uplink D2R are [f A +offset1,fA+offset1+BW] and [f A +offset2,f A +offset2+BW).

[0239] For example, if the first device's D2R is not a double-sideband transmission, but rather a single-sideband transmission, and the second offset value is offset1, then the lowest frequency of one sideband transmitted by the first device's D2R is f. A +offset1, the transmit bandwidth occupied by the D2R transmission of the first device is BW, then the frequency domain resources occupied by the device's uplink D2R transmission are [f A +offset1,f A +offset1+BW].

[0240] In some embodiments, the highest position of the sideband is determined based on the reference frequency point and the second offset value, and the frequency domain resources are determined based on the highest position of the sideband and the bandwidth occupied by the uplink transmission.

[0241] For example, if the first device uses dual-sideband D2R transmission, and the second offset values ​​corresponding to the two sidebands are offset1 and offset2 respectively, then the highest frequency points of the two sidebands in this D2R transmission of the first device are f1 and offset2 respectively. A +offset1 and f A +offset2, the frequency domain resources occupied by the two sidebands transmitted by the first device in the uplink D2R are [f A +offset1-BW,f A +offset1] and [f A +offset2-BW, f A +offset2).

[0242] For example, if the first device's D2R is not a double-sideband transmission, but rather a single-sideband transmission, and the second offset value is offset1, then the highest frequency of one sideband transmitted by the first device's D2R in this instance is f. A +offset1, the transmit bandwidth occupied by the D2R transmission of the first device is BW, then the frequency domain resources occupied by the device's uplink D2R transmission are [fA +offset1-BW,f A +offset1).

[0243] In step S2204, the first device 101 sends uplink information to the second device 102.

[0244] In some embodiments, the second device 102 receives uplink information sent by the first device 101.

[0245] In some embodiments, the first device may send uplink information to the second device based on determined frequency domain resources.

[0246] In this embodiment of the disclosure, the first position of the uplink transmitted frequency domain resource is determined based on the reference frequency point and the second offset value, which can ensure that the uplink transmitted frequency domain resource is different from the frequency domain resource where CW is located.

[0247] In this embodiment of the disclosure, different first devices can use different second offset values ​​to determine the frequency domain resources used for uplink transmission, thereby ensuring that different first devices use different frequency domain resources.

[0307] In some embodiments, step S4203 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0308] The communication method provided in this disclosure determines the frequency domain resources for uplink D2R transmission based on the frequency of the CW or the anchor frequency.

[0309] Option 1: Determine the frequency domain resources for uplink D2R transmission based on the frequency of CW.

[0310] Example 1: The frequency where CW is located is f1. The center position of the frequency domain resources occupied by the device's uplink transmission is determined by the formula f1×n+offset.

[0311] Example 2: The frequency where CW is located is f1. The lowest position of the frequency domain resources occupied by the device's uplink transmission is determined by the formula f1×n+offset.

[0312] Example 3: The frequency where CW is located is f1. The highest position of the frequency domain resources occupied by the device's uplink transmission is determined by the formula f1×n+offset.

[0313] Among them, at least one of the n-values ​​and offset values ​​is different for different devices. The network device is configured with a set of n-values ​​and offset values. Different devices use different n-values ​​and / or offset values. The configuration of n-values ​​and offset values ​​can ensure that the spectrum where the device's D2R transmission is located and the spectrum where the CW is located are located on different spectrums.

[0314] Example: If a network device is configured with a set of combinations of n and offset values ​​as {(n=1, offset1), (n=1, offset2), (n=1, offset3) ... (n=2, offset4)}, then device1 can use (n=1, offset1) to determine the center position of the resources occupied by the uplink transmission, device2 can use (n=1, offset2) to determine the center position of the resources occupied by the uplink transmission, ..., device4 can use (n=2, offset4) to determine the center position of the resources occupied by the uplink transmission.

[0315] If the set of combinations of n and offset values ​​contains M combinations of n and offset values, then the number of FDM devices supported by the uplink is M.

[0316] The set of n-values ​​and offset values ​​is configured or pre-configured to the terminal by the network device through higher-layer signaling, or indicated to the terminal through broadcast information, notified to the terminal in the broadcast channel, or notified to the terminal in the system message SIB, or indicated to the terminal in the paging message or repaging message.

[0317] When a device sends an uplink for the first time, such as when the device sends message (Msg)1 to the network device, the device randomly selects a pair of n and offset values ​​from the set of n and offset values ​​for its own D2R transmission.

[0318] In uplink transmissions that are not the first time a device sends an uplink message, such as when a device sends Msg3 to a network device, the network device indicates the index corresponding to the n value and offset value used by a certain device in the downlink R2D information.

[0319] Downlink R2D information can be R2D control information, specifically an index indicating the n and offset values ​​within the R2D control information. Alternatively, it can be an index indicating the n and offset values ​​in msg2, which is the response from the network device to msg1 sent by the device.

[0320] For example, if the device sends Msg1 as RN1, then when the network device replies to the device with Msg2, it carries the index of the n value and the offset value, that is, it replies with ACK+RN16+index, the length of the index is log2(X), and the value of X is the number in the set of combinations of n value and offset value.

[0321] Define the mapping relationship between index, n value and offset value. The set of n value and offset value combinations is {(n=1, offset1), (n=1, offset2), (n=1, offset3), (n=2, offset4), (n=2, offset5), (n=2, offset6)}, which has a total of 6 pairs of values. Then, 3 bits are used to indicate a certain pair of n value and offset value, as shown in Table 1.

[0322] Based on the above method, the frequency domain resources occupied by the device's uplink D2R transmission are further determined using the following method.

[0323] For Example 1, it was determined in the following way:

[0324] The device's D2R is a double-sideband transmission. According to the above embodiment 1, the center frequencies of the two sidebands of the device's D2R transmission are f1×n+offset1 and f1×n+offset2, respectively. The transmission bandwidth occupied by the device's D2R transmission is BW. Therefore, the frequency domain resources occupied by the two sidebands of the device's uplink D2R transmission are [f1×n+offset1+1 / 2BW, f1×n+offset1-1 / 2BW] and [f1×n+offset2+1 / 2BW, f1×n+offset2-1 / 2BW], respectively. The bandwidth BW can be defined by the protocol, pre-configured by the network device, or a fixed value configured, or indicated by the R2D downlink information.

[0325] If the device's D2R transmission is not double-sideband, for example, if the uplink D2R transmission is single-sideband, then the center frequency of one sideband of the device's D2R transmission is determined to be f1×n+offset1 according to the above embodiment 1. The transmission bandwidth occupied by the device's D2R transmission is BW, then the frequency domain resources occupied by the device's uplink D2R transmission are [f1×n+offset1+1 / 2BW, f1×n+offset1-1 / 2BW].

[0326] For Example 2, it was determined in the following way:

[0327] The device's D2R is a double-sideband transmission. Therefore, the lowest positions of the two sidebands of the device's D2R transmission are determined to be f1×n+offset1 and f1×n+offset2 according to the above embodiment 1. The transmission bandwidth occupied by the device's D2R transmission is BW. Then, the frequency domain resources occupied by the two sidebands of the device's uplink D2R transmission are [f1×n+offset1, f1×n+offset1+BW] and [f1×n+offset2, f1×n+offset2+BW], respectively. The bandwidth BW can be defined by the protocol, pre-configured by the network device, or a fixed value configured, or indicated by the R2D downlink information.

[0328] If the device's D2R is not a double-sideband transmission, then the lowest position of the bandwidth occupied by the device's D2R transmission is determined to be f1×n+offset1 according to the above embodiment 1. The transmission bandwidth occupied by the device's D2R transmission is BW, then the frequency domain resources occupied by the device's uplink D2R transmission are [f1×n+offset1, f1×n+offset+BW].

[0329] For Example 3, it was determined in the following way:

[0330] The device's D2R is a double-sideband transmission. Therefore, the highest positions of the two sidebands of the device's D2R transmission are determined to be f1×n+offset1 and f1×n+offset2 according to the above embodiment 1. The transmission bandwidth occupied by the device's D2R transmission is BW. Then, the frequency domain resources occupied by the two sidebands of the device's uplink D2R transmission are [f1×n+offset1-BW, f1×n+offset1] and [f1×n+offset2-BW, f1×n+offset2], respectively. The bandwidth BW can be defined by the protocol, pre-configured by the network device, or a fixed value configured, or indicated by the R2D downlink information.

[0331] If the device's D2R is not a double-sideband transmission, then the highest position of the bandwidth occupied by the device's D2R transmission is determined to be f1×n+offset1 according to the above embodiment 1. The transmission bandwidth occupied by the device's D2R transmission is BW, then the frequency domain resources occupied by the device's uplink D2R transmission are [f1×n+offset1-BW, f1×n+offset1].

[0332] Option 2: Based on a single anchor frequency point f A To determine the frequency domain resources for uplink D2R transmission.

[0333] Example 1: Using formula fA +offset determines the center position of the frequency domain resources occupied by the device's uplink transmission.

[0334] Example 2: Using formula f A +offset determines the lowest position of the frequency domain resources occupied by the device's uplink transmission.

[0335] Example 3: Using formula f A +offset determines the highest position of the frequency domain resources occupied by the device's uplink transmission.

[0336] The anchor frequency point f A It is not the frequency point where CW is located, but a common reference point for resources in a system.

[0337] The anchor frequency point f A The frequency point where CW is located is on a different spectrum. One anchor frequency point f is defined on the uplink spectrum and one on the downlink spectrum respectively. A .

[0338] The anchor frequency f of the uplink and downlink spectra A The value is configured or pre-configured to the terminal by the network device through higher-layer signaling, or indicated to the terminal through broadcast information, notified to the terminal in the broadcast channel, or through system message SIB, or indicated in the paging or repaging message as the anchor frequency point f. A Or anchor frequency f A It is specified in the protocol, and the network devices and terminals are known.

[0339] The offset is different for different terminals (devices). It is either pre-configured or configured by the network device for the terminal, or indicated to the terminal by the network device through R2D control signaling.

[0340] Example: If the frequency point where CW is located is on the uplink spectrum, then the anchor frequency point f A It is defined on the downlink spectrum; the network device controls the transmission of CW. Knowing the spectrum where the CW is located, it configures it to the terminal via higher-layer signaling, using 1 bit to indicate the current anchor frequency f. A It is defined on the downlink spectrum with a bit value of 0, indicating the current anchor frequency f. A It is defined on the downlink spectrum.

[0341] Example: If the frequency point where CW is located is on the downlink spectrum, then the anchor frequency point f AIt is defined on the uplink spectrum; the network device controls the transmission of CW. Knowing the spectrum where the CW is located, it configures it to the terminal via higher-layer signaling, using 1 bit to indicate the current anchor frequency f. A It is defined on the uplink spectrum, with a bit value of 1, indicating the current anchor frequency f. A It is defined on the uplink spectrum.

[0342] Based on the above method, the frequency domain resources occupied by the device's uplink D2R transmission are further determined using the following method.

[0343] For Example 1, it was determined in the following way:

[0344] The device's D2R is a double-sideband transmission. Therefore, the center frequencies of the two sidebands in this D2R transmission are determined according to Example 1 above, as f2. A +offset1,f A +offset2, the transmit bandwidth occupied by the device's D2R transmission is BW, then the frequency domain resources occupied by the two sidebands of the device's uplink D2R transmission are [f A +offset1+1 / 2BW,f A +offset1-1 / 2BW] and [f A +offset2+1 / 2BW,f A +offset2-1 / 2BW], where bandwidth BW can be a protocol definition, a pre-configured or configured fixed value of the network device, or an indicator of R2D downlink information.

[0345] If the device's D2R transmission is not double-sideband, for example, if the uplink D2R transmission is single-sideband, then the center frequency of one sideband of this device's D2R transmission is determined to be f according to the above embodiment 1. A +offset1, the transmit bandwidth occupied by the device's D2R transmission is BW, then the frequency domain resources occupied by the device's uplink D2R transmission are [f A +offset1+1 / 2BW,f A +offset1-1 / 2BW].

[0346] For Example 2, it was determined in the following way:

[0347] The device's D2R is a double-sideband transmission. Therefore, the lowest position of the two sidebands in this D2R transmission is determined as f according to the above embodiment 1. A +offset1 and f A+offset2, the transmit bandwidth occupied by the device's D2R transmission is BW, then the frequency domain resources occupied by the two sidebands of the device's uplink D2R transmission are [f A +offset1,f A +offset1+BW] and [f A +offset2,f A +offset2+BW], where bandwidth BW can be a protocol definition, a pre-configured or configured fixed value of the network device, or an indicator of R2D downlink information.

[0348] If the device's D2R is not a double-sideband transmission, then the lowest bandwidth occupied by the device's D2R transmission is determined to be f according to the above embodiment 1. A +offset1, the transmit bandwidth occupied by the device's D2R transmission is BW, then the frequency domain resources occupied by the device's uplink D2R transmission are [f A +offset1,f A +offset1+BW].

[0349] For Example 3, it was determined in the following way:

[0350] The device's D2R is a double-sideband transmission. Therefore, the highest position of the two sidebands in this D2R transmission is determined as f according to the above embodiment 1. A +offset1 and f A +offset2, the transmit bandwidth occupied by the device's D2R transmission is BW, then the frequency domain resources occupied by the two sidebands of the device's uplink D2R transmission are [f A +offset1-BW,f A +offset1] and [f A +offset2-BW, f A +offset2], where bandwidth BW can be a protocol definition, a pre-configured or configured fixed value of the network device, or an indicator of R2D downlink information.

[0351] If the device's D2R is not a double-sideband transmission, then the highest bandwidth occupied by the device's D2R transmission is determined to be f according to the above embodiment 1. A +offset1, the transmit bandwidth occupied by the device's D2R transmission is BW, then the frequency domain resources occupied by the device's uplink D2R transmission are [f A +offset1-BW,f A +offset1).

[0352] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.
