Description

Method and device for determining resource of excitation signal

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 2, 2024, with application number 202410156696.0 and application name “Method and device for determining resources of excitation signals”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a method and device for determining resources of an excitation signal. Background Art

[0003] Radio Frequency Identification (RFID) is a passive IoT technology that uses radio frequency (RF) for contactless, two-way data communication. It uses RF to read and write to recording media (electronic tags or radio frequency cards), thereby achieving target identification and data exchange. However, due to its limited coverage range of approximately 10 meters, this technology is unlikely to support the trillion-level demand expected in the future. Therefore, the Third Generation Partnership Project (3GPP) is currently discussing the development of passive IoT technology based on cellular communications. This can reduce costs by leveraging existing large-scale cellular infrastructure, while also leveraging many mature cellular communication technologies, such as interference management and mobility management, to enhance the coverage of passive IoT. One of the more important applications of passive IoT technology is the processing of excitation signals by devices, such as backscattering and charging. Because network devices transmit on the downlink frequency, the devices must backscatter the excitation signal on the uplink frequency. In frequency division duplex (FDD) systems, the uplink and downlink frequencies differ. If a device lacks frequency shifting capabilities, the excitation signal cannot be directly sent from the network device to the device. Ensuring that the device effectively receives the excitation signal is a pressing issue. Summary of the Invention

[0064] Internet of Things (IoT) practitioners have reached a consensus on the classification of IoT nodes into three different speed levels, namely high-speed IoT, medium-speed IoT, and low-speed IoT. High-speed IoT is primarily supported by technologies such as 5G enhanced mobile broadband (eMBB), 4G Category 4+, and Wi-Fi 6. Medium-speed IoT is primarily supported by 4G Category 1, 3G, and 2G. Low-speed IoT is primarily supported by technologies such as NB-IoT, LoRaWAN, and BLE. These different speeds correspond to different power consumption levels, creating three distinct scenarios and requiring three different scales of IoT connections. Figure 1 shows a schematic diagram of IoT connection sizes across different tiers. Among them, low-speed IoT standards such as NB-IoT, LoRaWAN, and BLE can support tens of billions of connections, while medium-speed and high-speed IoT standards can only support a much smaller scale of connections than low-speed IoT. Based on the above three types of IoT scenarios, passive IoT will become the main source of hundreds of billions of IoT connections.

[0065] Main application scenarios of the Internet of Things:

[0066] Industrial sensor networks: Industrial sensor networks are primarily used in industrial production processes, such as temperature and humidity monitoring, vibration monitoring, and production line monitoring, enabling industrial automation and intelligent management. For example, by deploying zero-power sensing devices beneath the tracks, they can monitor and collect track pressure, temperature, and other information. Furthermore, these devices can be deployed in extreme environments, such as those with high and low temperatures, moving or rotating parts, high vibration, and high humidity, where battery life is limited.

[0067] Logistics and warehousing: With the continued growth of the logistics industry, companies are facing increasing pressure on warehousing and labor costs. Digital management of logistics packages can not only further improve logistics and warehousing management efficiency, but also save high labor costs. Zero-power communication technology affixes communication terminal logos to the surface of packages or goods packaging, allowing for the acquisition of logistics information and management of the entire logistics process, making warehousing operations simpler and more efficient.

[0068] Smart wearables: After mobile phones, smart wearables are among the most promising consumer devices for large-scale applications. Currently, various wearable devices have wireless connectivity. Depending on the functional positioning of each product, they can be used in a variety of scenarios, including health monitoring, exercise monitoring, motion sensing, and mobile positioning. Zero-power communication technology aims to ultimately break free from battery constraints, achieving longer battery life, more convenient energy security, and a better user experience.

[0069] Healthcare: Portable medical devices can meet consumers' needs for home health services, but the unique characteristics of medical monitoring devices (especially implantable ones) significantly limit their application scenarios due to issues such as battery life and portable power supplies. Zero-power IoT technology can achieve extremely low power consumption. Furthermore, the lack of batteries reduces size, facilitates flexible folding, and eliminates the need for liquid immersion. This will facilitate real-time monitoring of medical device data and efficient digital management of health conditions.

[0070] Smart home: The application of zero-power communication technology in the smart home field can get rid of complex wiring, enable each terminal to be independently controlled, and achieve long-term online operation without the need for human energy intervention.

The network device may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario. The network device may also be a base station device in a fifth generation mobile communication system (5G) network or next generation wireless communication, or a network device in a future evolved public land mobile network (PLMN) network.

Device A: lacks energy storage and the ability to generate / amplify independent signals, but can perform backscatter transmission. Device B: possesses energy storage, lacks the ability to generate independent signals, and can perform backscatter transmission. Device B uses the stored energy to amplify reflected signals. Devices A and B do not have frequency shifting capabilities.

[0074] Optionally, the communication system further includes an excitation source 203. The excitation source is used to generate an excitation signal. For example, the excitation source generates an excitation signal under the control of the network device and sends the excitation signal to the first device.

[0075] The communication system can be applicable to the Long Term Evolution (LTE) system, the Universal Mobile Telecommunications System (UMTS) system, the Code Division Multiple Access (CDMA) system, the Wireless Local Area Network (WLAN) or the fifth generation mobile communication system (5G) or the next generation wireless communication system, etc.

[0076] In this embodiment of the present application, network device 201 transmits first information of an excitation signal to first device 202. In response, first device 202 receives the first information. Optionally, first device 202 predefines second information of the excitation signal. First device 202 determines a transmission resource based on the first information and / or the second information. Excitation source 203 generates an excitation signal and transmits it to first device 202. In response, first device 202 receives the excitation signal from excitation source 203 based on the transmission resource.

[0077] Please refer to FIG3 , which is a flow chart of a method for determining a resource of an excitation signal provided by an embodiment of the present application. The method includes but is not limited to the following steps:

[0078] S301: A network device sends first information of an excitation signal to a first device. Correspondingly, the first device receives the first information from the network device.

[0079] The first information is used by the first device to determine transmission resources, and the transmission resources are used by the first device to receive the excitation signal.

[0080] The first information includes resource type indication information of the excitation signal; or, the first information includes resource location indication information of the excitation signal; or, the first information includes resource type indication information of the excitation signal and resource location indication information of the excitation signal; or, the first information includes a first resource set; or, the first information includes a first resource set and a first resource determination rule; or, the first information includes a first resource set and a resource determination rule set, the transmission resource is determined according to the first resource set and the first resource determination rule, and the resource determination rule set includes the first resource determination rule; or, the first information includes the resource location of the baseline; or, the first information includes the resource location of the baseline and the second resource determination rule; or, the first information includes the resource location of the baseline and an offset value set.

[0081] The resource type indication information of the excitation signal is used to indicate the resource type of the transmission resource. Optionally, the resource type of the transmission resource can be divided according to the resource level, and the resource level can be divided according to the size of the resource, that is, the resource level refers to the level of the resource size. For example, the resource type of the transmission resource can include frequency domain resource unit levels such as RB (Resource Block) level, RE (Resource Element) level and RE group level, or the resource type of the transmission resource can be a redefined frequency domain resource unit level. The resource type of the transmission resource can also be divided in other ways, which are not limited here.

[0082] It should be noted that the resource type indication information of the excitation signal can be used to directly indicate the resource type of the transmission resource. For example, the first information indicates the resource type of the excitation signal in the form of bit information, that is, the first information includes 1 bit, 1 can represent the RB level, 0 can represent the RE level, or the first information includes 2 bits, 00 can represent the RB level, 01 represents the RE level, and 10 represents the RE group level. The values ​​of each bit can also be interchanged. The resource type indication information of the excitation signal can also indicate the resource type of the excitation signal from a predefined plurality of resource types. For example, the first information indicates the resource type of the excitation signal from a predefined plurality of resource types in the form of bit information. 0 indicates that the first resource type from the plurality of resource types is the resource type of the excitation signal, and 1 indicates that the second resource type from the plurality of resource types is the resource type of the excitation signal.

[0083] The resource location information of the excitation signal is used to indicate the resource location of the transmission resource, for example, to indicate the resource index of the transmission resource, or to indicate other resource location information of the transmission resource. It should be noted that the resource location indication information of the excitation signal can be used alone to indicate the resource location of the transmission resource; or, the resource location information of the excitation signal can be combined with other information of the excitation signal to indicate the transmission resource. For example, the resource location information of the excitation signal can be combined with the resource type indication information of the excitation signal to indicate the resource location of the transmission resource, that is, the resource type indication information of the excitation signal indicates the resource type of the transmission resource, such as the RB level, and the resource location information of the excitation signal indicates the resource index under the resource type, such as RB0.

[0084] The first resource set includes one or more resources that are allowed to be used to transmit the excitation signal; or the first resource set includes a resource index, which is used to identify one or more resources that are allowed to be used to transmit the excitation signal. The resources included in the first resource set or the resources identified by the included resource index may include but are not limited to time domain resources, frequency domain resources, code domain resources, spatial domain resources and / or other resources that can be used to transmit the excitation signal. In the case where the first resource set includes multiple types of resources, the multiple resource types can exist independently in the first resource set, for example, the first resource set includes time domain resources 1 and frequency domain resources 2; or, the multiple resource types can exist in the first resource set in a matched group, for example, the first resource set includes time-frequency resources 1 and time-frequency resources 2, wherein time-frequency resources 1 and time-frequency resources 2 include time domain resources and frequency domain resources. In the case where the first resource set includes resource indexes of multiple types of resources, the indexes of multiple resource types can exist separately and independently in the first resource set, for example, the first resource set includes time domain resource index 1 and frequency domain resource index 2; or, the indexes of multiple resource types can be matched into groups and exist in the first resource set, for example, the first resource set includes time-frequency resource index 1 and time-frequency resource index 2.

[0085] The first resource determination rule is a rule for determining transmission resources from the first resource set. For example, the first resource determination rule is a rule for determining transmission resources from the first resource set based on the device identifier of the first device. For another example, the first resource determination rule is a rule for instructing the first device on the transmission of the corresponding resource (for example, the first resource). Optionally, the network device may determine the first resource determination rule for the first device based on the situation of the first device within the signal radiation range of its cell, carry the first resource determination rule in a broadcast message and send it to the first device, and instruct different first devices to transmit on different resources in the first resource determination rule. For example, when the number of first devices within the signal radiation range of the cell of the network device exceeds the device number threshold, the network device determines the first resource determination rule, the first resource determination rule is a rule for instructing the first device on the transmission of the corresponding resource, and carries the first resource determination rule in a broadcast message and sends it to the first device.

[0086] The resource determination rule set includes multiple resource determination rules. Optionally, different resource determination rules in the multiple resource determination rules apply to different communication situations, or different resource determination rules apply to different first devices. The network device sends the resource determination rule set to the first device. The first device may determine the first resource determination rule from the resource determination rule set based on the communication situation of the current cell. For example, the first device may perform cell measurement and determine the first resource determination rule from the resource determination rule set based on the cell measurement results, or determine the first resource determination rule from the resource determination rule set based on its own device identifier. The first resource determination rule is also included in the resource determination rule set.

[0087] The baseline is the resource location boundary that demarcates resources permitted for excitation signal transmission from those prohibited. The baseline's resource location is the starting resource location for the transmission resources determined by the first device for receiving the excitation signal. The first device can superimpose a corresponding resource offset value on the baseline's resource location to obtain the transmission resources corresponding to the first device.

[0088] The second resource determination rule is a rule for determining transmission resources based on the resource location of the baseline. The second resource determination rule includes: superimposing a first operation value on the resource location of the baseline, the first operation value is obtained by performing an operation based on the attribute information of the first device or the communication-related information of the first device, wherein the operation may include but is not limited to modulo operation, operation through hash function or other operations, the attribute information of the first device may include but is not limited to the device identifier of the first device, etc., the communication-related information of the first device includes but is not limited to C-RNTI (Cell-Radio Network Temporary Identifier, cell wireless network temporary identifier), RNTI (Radio Network Temporary Identifier, wireless network temporary identifier) ​​specially configured for the first device, etc.

[0089] Optionally, the second resource determination rule includes: superimposing a first modulo value on the baseline resource position to obtain the resource position of the transmission resource, where the first modulo value is obtained by performing a modulo operation on the device identifier of the first device and the first resource quantity, and the first resource quantity is the number of resources allowed to be used to transmit the excitation signal. That is, the second resource determination rule is base line + device ID mod N, where base line is the baseline resource position, device ID is the device identifier of the first device, and N is the first resource quantity. Optionally, the first resource quantity can be configured for the first device by the network device through dynamic scheduling, semi-static scheduling, or other scheduling methods.

[0090] Optionally, the second resource determination rule includes: superimposing a second modulus value on the resource position of the baseline, the second modulus value being obtained by performing a modulus operation on the C-RNTI of the first device and the first resource quantity, and the first resource quantity being the number of resources allowed to be used to transmit the excitation signal.

[0091] Optionally, the second resource determination rule includes: superimposing a third modulus value on the resource position of the baseline, the third modulus value being obtained by performing a modulus operation on the RNTI specially configured for the first device and the first resource quantity, and the first resource quantity is the number of resources allowed to be used to transmit the excitation signal.

[0092] Optionally, the second resource determination rule includes: adding a first hash operation value to the resource location of the baseline to obtain the resource location of the transmission resource, and the first hash operation value is obtained by performing a hash function on the device identifier of the first device.

[0093] Optionally, the second resource determination rule includes: superimposing a second hash operation value on the resource location of the baseline to obtain the resource location of the transmission resource, and the second hash operation value is obtained by performing a hash function on the C-RNTI of the first device.

[0094] Optionally, the second resource determination rule includes: superimposing a third hash operation value on the resource location of the baseline to obtain the resource location of the transmission resource, and the third hash operation value is obtained by operating the RNTI specially configured for the first device through a hash function.

[0095] It should be noted that the above is only an example of the second resource determination rule and does not constitute a limitation on the second resource determination rule. In addition, the second resource determination rule can be applied to the case where the signal quality within the signal radiation range of the broadcast channel or the signal radiation range of the service cell where the first device is currently located is within the signal quality threshold range. In this case, the number of devices within the signal radiation range of the broadcast channel or the signal radiation range of the service cell is within the device number threshold range. The transmission resources obtained by the second resource determination rule for different first devices will not be the same, and will not cause the multiplexing of transmission resources for receiving the excitation signal; and when the signal quality is not within the signal quality threshold range, the number of devices within the signal radiation range of the broadcast channel or the signal radiation range of the service cell may be large, and determining the transmission resource by the second resource determination rule will cause multiple first devices to reuse the same transmission resource. At this time, other methods can be used to determine the transmission resource. For example, the network device instructs the first device through the first information to receive the excitation signal on the determined first resource, and the transmission resources for receiving the excitation signal are different for different first devices.

[0096] The offset value set includes one or more offset values. Different offset values ​​in the offset value set correspond to different device identifiers. After receiving the offset value set, the first device can determine a first offset value from the offset value set based on its own device identifier, and determine the resource location of the transmission resource for receiving the excitation signal based on the resource location of the baseline and the first offset value. The first offset value is included in the offset value set.

[0097] The network device may send the first information of the excitation signal to the first device in the following manner:

[0098] In a first manner, the network device sends first information of an excitation signal to the first device based on a broadcast message, and the first device receives the first information sent by the network device.

[0099] In the first method, the first information is carried by a broadcast message, that is, the first information is transmitted based on the broadcast message. The broadcast message is a broadcast message of the passive Internet of Things system or the environmental Internet of Things system itself, and is carried by the physical broadcast channel (PBCH). The physical broadcast channel is an information channel of the physical layer that transmits information by broadcasting, which defines the time-frequency resources and DMRS (Demodulation Reference Signal). The network device sends a broadcast message, and accordingly, the first device receives the broadcast message and can obtain the first information of the excitation signal based on the broadcast message.

[0100] Optionally, the first information is carried in the broadcast message, and the first information may be indicated or determined based on, but not limited to, one of the following:

[0101] (1) Bit information in the broadcast message;

[0102] (2) Scrambling information of the broadcast message;

[0103] (3) Encoded information of the broadcast message;

[0104] (4) The index of the synchronization sequence in the broadcast message;

[0105] (5) The cyclic redundancy check (CRC) mask of the broadcast message;

[0106] (6) The number of bits in the CRC of the broadcast message;

[0107] (7) Beam ID of the broadcast message, i.e., the beam ID of the broadcast channel.

[0108] The above information (1)-(7) can be used to indicate or determine the first information separately, or can be used in combination with at least two of the above information to indicate or determine the first information.

[0109] Optionally, the above information (1)-(7) may be used to indicate or determine the first information separately, as follows:

[0110] For (1), the first information is indicated by the bit information in the broadcast message. For example, the broadcast message includes the first bit information, and the first bit information is the resource location indication information of the excitation signal. 0 can indicate that the excitation signal is transmitted on the first resource, and 1 can indicate that the excitation signal is transmitted on the second resource. 0 or 1 can also indicate the reverse. For another example, the first bit information is 1 to indicate the RE information of the transmission resource. That is, different bit values ​​of the first bit information can correspond to different resources or different resource locations. For another example, the broadcast message includes the first bit information and the second bit information, the second bit information is the resource type indication information of the excitation signal, the first bit information is the resource location indication information of the excitation signal, the second bit information is 0 to indicate that the resource type of the transmission resource of the excitation signal is RE level, and the first bit information indicates the specific RE index of the transmission resource.

[0111] For (2), the first information is determined based on the scrambling information of the broadcast message. For example, different scrambling information corresponds to different transmission resource locations, and the first device can determine the resource location of the transmission resource by obtaining the scrambling information of the broadcast message.

[0112] For (3), the first information is determined based on the coding information of the broadcast message. For example, different coding information corresponds to different transmission resource locations, and the first device can determine the resource location of the transmission resource by obtaining the coding information of the broadcast message.

[0113] For (4), the first information is determined based on the index of the synchronization sequence in the broadcast message. For example, different synchronization sequence indices correspond to different resource location indices of the transmission resource. The first device obtains the index of the synchronization sequence in the broadcast message and can obtain the resource location index of the transmission resource based on the index of the synchronization sequence.

[0114] For (5), the first information is determined based on the CRC mask of the broadcast message. For example, different CRC masks correspond to different transmission resource locations, and the resource location of the transmission resource can be obtained based on the CRC mask. For another example, the first resource set is determined based on the CRC mask of the broadcast message, and each bit of the mask corresponds to a resource location index.

[0115] For (6), the first information is determined based on the number of bits in the CRC of the broadcast message. For example, a modulo operation can be performed based on the number of bits in the CRC and the device identifier of the first device, and the resource location index of the transmission resource can be determined based on the obtained modulo operation result. For another example, the number of bits in the CRC of the broadcast message corresponds to the resource location of the transmission resource, and the resource location index of the transmission resource can be obtained based on the number of bits in the CRC of the broadcast message.

[0116] For (7), the first information is determined based on the beam identifier of the broadcast message, where the beam identifier is used to identify the beam. For example, the beam identifier of the broadcast message corresponds to the resource location of the transmission resource, and the resource location index of the transmission resource can be obtained based on the beam identifier of the broadcast message.

[0117] Optionally, the first information may be indicated or determined by combining at least two of the information (1) to (7), as follows:

[0118] For example, the resource type of the transmission resource is determined based on the scrambling information of the broadcast message, and the resource location index of the transmission resource under the resource type is determined based on the indication of the bit information in the broadcast message. Another example is the resource location of the baseline is determined based on the index of the synchronization sequence in the broadcast message, and the offset value set is determined based on the bit information in the broadcast message. Another example is the resource determination rule set is determined based on the CRC mask of the broadcast message, and the first resource set is determined based on the beam identifier of the broadcast message.

[0119] It should be noted that the above information (1)-(7) is used separately to indicate or determine the first information, or is used in combination with at least two of the information (1)-(7) to indicate or determine the implementation method of the first information. This is only an example and does not constitute a limitation. Other information in the broadcast message and / or other methods can also be used to indicate or determine the first information.

[0120] In the second approach, the network device transmits the first information of the excitation signal to the first device over a dedicated channel. Specifically, the first information is carried over the dedicated channel. The dedicated channel is configured to transmit the first information of the excitation signal, so that the first information of the excitation signal is transmitted as independent information. The network device transmits the dedicated channel, and the first device receives the dedicated channel in response to obtain the first information.

[0121] In the third way, the network device sends the first information of the excitation signal to the first device based on the public control information, that is, the first information is carried by the public control information. The public control information is carried by the Physical Downlink Control Channel (PDCCH), which is the control information sent to all users in the cell. For example, the public control information may include but is not limited to one or more of the following information: random access response, paging-related messages, system information, and messages directed to multiple terminal devices. PDCCH is a control channel of the physical layer (Physical Layer), which can be a dedicated control channel or a public control channel according to scheduling. The network device sends the public control information through the PDCCH, and accordingly, the first device receives the public control information through the PDCCH to obtain the first information.

[0122] Optionally, for the second and third methods, on the network device side, the first information is sent before the access resource. Correspondingly, on the first device side, the first information is received before the access resource. The access resource is used for the first device to access the network device, for example, for the first device to access the network device to send a first signal to the network device, where the first signal is obtained by the first device backscattering the excitation signal. The first information is transmitted before the access resource, so that the first device can receive the first information before sending the first signal to the network device, and determine the transmission resource for receiving the excitation signal based on the first information, which is beneficial for the first device to receive the excitation signal on the transmission resource to backscatter the excitation signal.

[0123] Optionally, for the second and third modes, on the network device side, the first information is sent in a sequence form, or the first information is sent in a bit information form. Correspondingly, on the first device side, the first information is transmitted in a sequence form, or the first information is transmitted in a bit information form. For example, the first information is carried in a sequence form on a dedicated channel or a common control channel, or the first information is carried in a bit information form on a dedicated channel or a common control channel.

[0124] S302: The first device determines a transmission resource based on first information of the excitation signal and / or second information of the excitation signal, where the first information comes from the network device and the second information is predefined information. The transmission resource is used by the first device to receive the excitation signal.

[0125] The excitation signal received by the first device can be used for backscattering, charging, and other functions of the first device, and may also be used to implement other functions, which are not limited here. The first information comes from the network device, that is, the first information is obtained in step S301; the second information is predefined information, which can be predefined on the first device; optionally, the second information can also be predefined on the network device and / or the excitation source.

[0126] The first device determines the transmission resource in the following three ways:

[0127] Method 1: The first device determines the transmission resource according to the first information of the excitation signal.

[0128] The first device may determine the transmission resource for receiving the excitation signal based on the first information, or the first device may determine the transmission resource for receiving the excitation signal based on the first information and the third information. The third information may include attribute information of the first device itself, such as the device identification of the first device and the network standard supported by the first device; and / or the third information may include communication measurement information of the first device, such as measurement result information obtained by the first device through cell measurement; and / or the third information may also include other communication-related information that can be obtained by the first device. For example, when the first information includes a first resource set and a resource determination rule set, the third information may be the cell measurement result obtained by the first device through cell measurement. When the cell measurement result indicates that the signal quality of the serving cell currently located by the first device is poor, it may be because there are many devices within the signal coverage range of the current serving cell. In this case, the first resource determination rule in the resource determination rule set may be determined, and different first devices are instructed in the first resource determination rule to transmit on different resources. For example, when the cell measurement results indicate that the signal quality of the service cell where the first device is currently located is good, it may be because there are fewer devices within the signal coverage range of the current service cell. In this case, the first resource determination rule in the resource determination rule set can be determined. The first resource determination rule is a rule for determining transmission resources from the first resource set based on the device identifier of the first device.

[0129] Optionally, the first information includes resource type indication information of the excitation signal. For example, the first device may determine the resource type of the excitation signal based on the resource type indication information of the excitation signal, and determine the transmission resource from the resources of the resource type of the excitation signal based on the third information.

[0130] Optionally, the first information includes resource location indication information of the excitation signal. For example, the resource location indication information of the excitation signal is a resource location index of the excitation signal, and the first device can determine the resource location index of the transmission resource according to the resource location indication information of the excitation signal.

[0131] Optionally, the first information includes resource type indication information and resource location indication information of the excitation signal. For example, the first device may determine the resource type of the excitation signal based on the resource type indication information of the excitation signal, and determine the resource location index of the transmission resource in the resources of the resource type of the excitation signal based on the resource location indication information of the excitation signal.

[0132] Optionally, the first information includes a first resource set. For example, the first device may determine the transmission resource from the first resource set according to the third information.

[0133] Optionally, the first information includes a first resource set and a first resource determination rule, where the first resource determination rule is a rule for determining a transmission resource from the first resource set. For example, the first device may determine a transmission resource, an index of a transmission resource, or a resource location index of a transmission resource from the first resource set according to the first resource determination rule.

[0134] Optionally, the first information includes a first resource set and a resource determination rule set, the transmission resource is determined based on the first resource set and the first resource determination rule, and the resource determination rule set includes the first resource determination rule. For example, the first device may determine the first resource determination rule from the resource determination rule set based on the third information, and determine the transmission resource, an index of the transmission resource, or a resource location index of the transmission resource from the first resource set based on the first resource determination rule.

[0135] Optionally, the first information includes a resource location of the baseline. For example, the first device may determine the resource location of the transmission resource based on the third information and the resource location of the baseline.

[0136] Optionally, the first information includes the baseline resource location and a second resource determination rule, where the second resource determination rule is a rule for determining the transmission resource based on the baseline resource location. For example, the first device may superimpose the first modulo value on the baseline resource location based on the second resource determination rule to obtain the resource location of the transmission resource. The first modulo value is described in step S301 and is not further described here.

[0137] Optionally, the first information includes a baseline resource location and an offset value set, and the first device determines the transmission resource based on the first information of the excitation signal, including: the first device determining a first offset value from the offset value set based on the device identifier of the first device; and the first device determining the transmission resource based on the baseline resource location and the first offset value. Optionally, a modulo operation can be performed on the device identifier of the first device and the first resource quantity to obtain a first modulo value, and based on a mapping relationship between the modulo value and the offset value index and the first modulo value, the first offset value is determined from the offset value set, and the first offset value is superimposed on the baseline resource location to obtain the resource location of the transmission resource.

[0138] In a second approach, the first device determines transmission resources according to the first information from the network device and predefined second information.

[0139] In the second method, the first information may be carried in a broadcast message sent by the network device.

[0140] Optionally, the second information includes a resource type of the excitation signal, and the first information includes resource location indication information of the excitation signal, where the resource location indication information is used to determine a transmission resource from resources of the resource type. For example, the first device may determine the resource type of the excitation signal based on predefined second information, and determine a resource location index of the transmission resource within the resources of the resource type of the excitation signal based on the first information from the network device.

[0141] Optionally, the second information includes multiple resource types, and the first information includes resource type indication information of the excitation signal, where the resource type indication information is used to determine the resource type of the transmission resource from the multiple resource types. For example, the first device predefines the resource type of the excitation signal as RB level, RE group level, or RE level. The first device can determine the resource type of the transmission resource from the multiple resource types predefined on the first device based on the first information from the network device, and determine the transmission resource according to the device identifier of the first device within the resource type of the transmission resource.

[0142] Optionally, the first information includes a first resource set, and the second information includes a first resource determination rule, where the first resource determination rule is a rule for determining transmission resources from the first resource set. For example, the first device may determine the transmission resource from the first resource set from the network device according to a predefined first resource determination rule.

[0143] Optionally, the first information includes a resource location of the baseline, the second information includes a first offset value, and the transmission resource is determined based on the resource location of the baseline and the first offset value. For example, the first device may superimpose a predefined first offset value on the resource location of the baseline from the network device to obtain the resource location of the transmission resource.

[0144] Optionally, the first information includes a resource location of the baseline, and the second information includes a second resource determination rule, where the second resource determination rule is a rule for determining the transmission resource based on the resource location of the baseline. For example, the first device may determine the resource location of the transmission resource based on a predefined second resource determination rule and the resource location of the baseline from the network device.

[0145] Method three: the first device determines the transmission resource according to the second information of the excitation signal.

[0146] In one implementation, the second information includes first indication information, which indicates that the excitation signal is to be transmitted over a first resource. The first resource is a predefined, determined resource, i.e., the first indication information specifies that the excitation signal is to be transmitted over the determined first resource. Based on the first indication information, the first device can determine the transmission resource for transmitting the excitation signal.

[0147] Optionally, the first indication information may further indicate that the excitation signal is predefined on the first device in the form of a modulated signal or an unmodulated signal transmitted on the first resource. For example, the first indication information indicates that the excitation signal is an unmodulated signal transmitted on one RE, or the first indication information indicates that the excitation signal is a modulated signal transmitted on one RB, or the first indication information indicates that the excitation signal is an unmodulated signal transmitted on a group of REs (also referred to as an RE group).

[0148] In another implementation, the second information includes a rule for determining the index value of the transmission resource. The first device may determine the index value of the transmission resource according to the rule for determining the index value of the transmission resource.

[0149] Optionally, the rule for determining the index value of the transmission resource includes: a rule for determining the index value of the transmission resource based on the index value of the synchronization signal; or a rule for determining the index value of the transmission resource based on information about the access resource. The access resource is used for the first device to access the network device. For example, the index value of the transmission resource of the predefined excitation signal is related to the index value of the synchronization signal. The index value of the transmission resource can be determined based on the index value of the synchronization signal and the correlation between the index value of the transmission resource of the excitation signal and the index value of the synchronization signal. For another example, the mapping relationship between the information of the predefined access resource and the index value of the transmission resource can be determined based on the information of the access resource and the mapping relationship. Optionally, the information of the access resource can be scrambling information, coding information, frequency domain resource quantity information and / or time domain symbol quantity information of the access resource, etc. The information of the access resource is not limited here. It should be noted that the rule for determining the index value of the transmission resource can be determined based on other communication parameters used by the first device for communication, and is not limited to determination based on the index value of the synchronization signal or information about the access resource.

[0150] It should be noted that the information included in the first information and the second information above is only an example and not a limitation. The first information and the second information may also include other information so that the first device can determine the transmission resources for receiving the excitation signal based on the first information and / or the second information.
