Description

Resource configuration method and device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on August 11, 2023, with application number 202311018574.7 and invention name “Resource Allocation Method and Device”, 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 more specifically, to a resource configuration method and device. Background Art

[0003] Some wireless communication systems may support configured grant (CG) uplink transmissions. This means that a terminal device can use certain uplink resources that may be shared with other terminal devices to send uplink transmissions without specifically requesting the use of these resources or requiring specific authorization from the network device. CG transmissions do not require dynamic and explicit scheduling authorization from the network device. CG transmissions are sometimes also called grant-free (GF) transmissions.

[0004] CG transmission can be configured via radio resource control (RRC) signaling messages. The RRC signaling message may include one or more parameters for one or more terminal devices to pre-configure the CG transmission, wherein the one or more parameters include one or more parameter sets. CG transmission has a certain period, which may be referred to as the CG configuration period. The CG configuration period is represented by the periodicity field in the ConfiguredGrantConfig information element (IE).

[0005] Massive machine-type communication (mMTC) addresses the inadequacy of traditional mobile communications in supporting IoT and vertical industry applications, targeting low-power, high-connectivity scenarios. For example, mMTC can be applied to sensing and data collection applications such as smart cities, environmental monitoring, smart homes, and forest fire prevention. These applications require small data packets, low power consumption, and massive connections.

[0006] In the mMTC scenario, there are often sporadic services, and the interval between data packet arrivals is large. The interval between data packet arrivals may far exceed the CG configuration period, resulting in a waste of CG configuration resources.

[0007] Therefore, how to reduce the waste of CG configuration resources is an urgent problem to be solved.

[0008] Summary of the Invention

[0009] The present application provides a resource configuration method and apparatus, which can reduce the waste of configured grant (CG) configuration resources.

[0010] In a first aspect, a resource configuration method is provided, which is applied to a network device, and the method includes: determining first information, wherein the first information includes a first configuration authorization (configured grant, CG) configuration period, and the maximum transmission period corresponding to the first CG configuration period is greater than 640 milliseconds (ms); sending the first information to the terminal device.

[0011] Based on the above scheme, the maximum transmission period corresponding to the CG configuration period is greater than 640ms, so that when the data packet arrival interval is large (for example, the data packet arrival interval is greater than 640ms), the resource configuration method provided in the embodiment of the present application can enable the CG configuration period to match the actual data transmission period, thereby saving CG configuration resources.

[0012] In combination with the first aspect, in certain implementations of the first aspect, the terminal device is capable of supporting CG-small data transmission (SDT) service.

[0013] It should be understood that the CG-SDT service also includes the extended CG-SDT service, which is a service with an arrival interval much larger than 640 ms, such as a service that arrives every few minutes or hours.

[0014] The CG-SDT service can be understood as a small packet transmission service based on pre-configured resources. In the resource configuration method provided in the embodiment of the present application, the terminal device supports the CG-SDT service, which can reduce power consumption, reduce signaling overhead, improve network efficiency and reduce latency.

[0015] In combination with the first aspect, in certain implementations of the first aspect, the time domain symbol position corresponding to the CG-SDT service is related to the first CG configuration period and the system superframe number.

[0016] For sporadic services, the actual data transmission cycle may be several minutes or even hours. The resource configuration method provided in the embodiment of the present application introduces a superframe, which can support a larger CG configuration cycle. Compared with the solution that determines the time domain symbol position only by the number of wireless frames, the number of time slots and the number of symbols, the resource configuration method provided in the embodiment of the present application is expanded from 1024 wireless frames to 1024 superframes, an increase of 1024 times, so that the CG configuration cycle can match the hourly service transmission cycle, thereby saving CG configuration resources and reducing the overhead of network equipment.

[0017] In combination with the first aspect, in some implementations of the first aspect, the maximum transmission period corresponding to the first CG configuration period includes any one of 1280ms, 2560ms, 5120ms, 10240ms, 20480ms, 40960ms, 81920ms, 163840ms, 327680ms, 655360ms, 1310720ms, 2621440ms and 5242880ms.

[0018] Based on the above scheme, the maximum transmission period corresponding to the CG configuration period is greater than 640ms, and there are multiple options, so that when the interval between data packet arrivals is large, the CG configuration period can match the service transmission period of seconds, minutes or hours, thereby saving CG configuration resources.

[0019] In combination with the first aspect, in certain implementations of the first aspect, sending the first information to the terminal device includes: sending radio resource control (RRC) signaling, wherein the RRC signaling carries the first information, the first information also includes a period extension field, and the period extension field includes the first CG configuration period.

[0020] Based on the above solution, the first CG configuration period can be located in the period extension field. Thus, when a terminal device receives the first information containing the period extension field, it can transmit data packets according to the first CG configuration period. The first CG configuration period can match the period of actual data packet transmission, thereby saving CG configuration resources and reducing network device overhead.

[0021] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: sending second information to the terminal device, wherein the second information includes a second CG configuration period, and the second CG configuration period is smaller than the first CG configuration period.

[0022] Based on the above solution, network devices can be configured with different CG configuration periods, allowing terminal devices to flexibly select according to service needs. For example, for services with large packet arrival intervals, the first CG configuration period can be selected, thereby saving CG configuration resources and reducing network device overhead. For services with small packet arrival intervals, the second CG configuration period can be selected to maintain the efficiency of uplink data transmission.

[0023] In combination with the first aspect, in certain implementations of the first aspect, the first CG configuration period and the second CG configuration period are carried in RRC signaling, the RRC signaling includes a period field and a period extension field, and the period field includes the second CG configuration period.

[0024] Based on the above solution, network devices can configure different CG configuration periods in RRC signaling, allowing terminal devices to flexibly select according to service needs. For example, for services with large data packet arrival intervals, the first CG configuration period can be selected, thereby saving CG configuration resources and reducing network device overhead. For example, for services with small data packet arrival intervals, the second CG configuration period can be selected, thereby not reducing the transmission efficiency of uplink data.

[0025] In combination with the first aspect, in certain implementations of the first aspect, the period extension field is used for the first type of terminal device to determine the CG configuration period, and the period field is used for the second type of terminal device to determine the CG configuration period.

[0026] Based on the above scheme, the resource configuration method provided in the embodiment of the present application can configure different CG configuration periods for multiple types of terminal devices. Among them, the CG configuration period of the first type of terminal device is greater than the CG configuration period of the second type of terminal device. The capability of the first type of terminal device is relatively low, and the data packet arrival interval is large, while the capability of the second type of terminal device is relatively high, and the data packet arrival interval is small. Therefore, the CG configuration period of each type of terminal device can respectively match the actual data transmission period of the terminal device of that type, thereby saving CG configuration resources for the first type of terminal device. For the second type of terminal device, sufficient CG configuration resources are configured without reducing the transmission efficiency of uplink data.

[0027] In combination with the first aspect, in certain implementations of the first aspect, the association period corresponding to the first CG configuration period is 1, and there is at least one synchronization signal block SSB index mapped to a valid transmission opportunity in the association period.

[0028] In combination with the first aspect, in certain implementations of the first aspect, determining the first information includes: determining the first CG configuration period based on the load of the network device.

[0029] Based on the above solution, network devices can determine the CG configuration period based on load conditions. For example, when the network load is high, the CG configuration period can be longer, and when the load is light, the CG configuration period can be shorter, thereby improving network utilization and reducing the failure rate of the communication system.

[0030] In the second aspect, a resource configuration method is provided, which is applied to a terminal device, and the method includes: receiving first information from a network device, wherein the first information includes a first configuration authorization CG configuration period, and the maximum transmission period corresponding to the first CG configuration period is greater than 640ms; sending a data packet to the network device according to the first information.

[0031] Based on the above scheme, the maximum transmission period corresponding to the CG configuration period is greater than 640ms, so that when the data packet arrival interval is large (for example, the data packet arrival interval is greater than 640ms), the resource configuration method provided in the embodiment of the present application can enable the CG configuration period to match the actual data transmission period, thereby saving CG configuration resources.

[0033] It should be understood that the CG-SDT service also includes an extended CG-SDT service, and the extended CG-SDT service is a service with an arrival interval much larger than 640 ms, such as a service that arrives every few minutes or hours.

[0034] The CG-SDT service can be understood as a small packet transmission service based on pre-configured resources. In the resource configuration method provided in the embodiment of the present application, the terminal device supports the CG-SDT service, which can reduce power consumption, reduce signaling overhead, improve network efficiency and reduce latency.

[0035] In combination with the second aspect, in certain implementations of the second aspect, sending data packets of the CG-SDT service to the network device based on the first information includes: determining the time domain symbol position corresponding to the data packet of the CG-SDT service based on the first CG configuration period and the system superframe number; and sending the data packet of the CG-SDT service to the network device based on the time domain symbol position.

[0036] For sporadic services, the actual data transmission cycle may be several minutes or even hours. The resource configuration method provided in the embodiment of the present application introduces a superframe, which can support a larger CG configuration cycle. Compared with the solution that determines the time domain symbol position only by the number of wireless frames, the number of time slots and the number of symbols, the resource configuration method provided in the embodiment of the present application is expanded from 1024 wireless frames to 1024 superframes, an increase of 1024 times, so that the CG configuration cycle can match the hourly service transmission cycle, thereby saving CG configuration resources and reducing the overhead of network equipment.

[0037] In combination with the second aspect, in some implementations of the second aspect, the maximum transmission period corresponding to the first CG configuration period includes any one of 1280ms, 2560ms, 5120ms, 10240ms, 20480ms, 40960ms, 81920ms, 163840ms, 327680ms, 655360ms, 1310720ms, 2621440ms and 5242880ms.

[0038] Based on the above scheme, the maximum transmission period corresponding to the CG configuration period is greater than 640ms, and there are multiple options, so that when the interval between data packet arrivals is large, the CG configuration period can match the service transmission period of seconds, minutes or hours, thereby saving CG configuration resources.

[0040] Based on the above solution, network devices can configure different CG configuration periods in RRC signaling, allowing terminal devices to flexibly select according to service needs. For example, for services with large data packet arrival intervals, the first CG configuration period can be selected, thereby saving CG configuration resources and reducing network device overhead. For example, for services with small data packet arrival intervals, the second CG configuration period can be selected, thereby not reducing the transmission efficiency of uplink data.

[0041] In combination with the second aspect, in certain implementations of the second aspect, the method further includes: receiving second information from the network device, wherein the second information includes a second CG configuration period, and the second CG configuration period is smaller than the first CG configuration period.

[0042] Based on the above solution, network devices can be configured with different CG configuration periods, allowing terminal devices to flexibly select according to service needs. For example, for services with large packet arrival intervals, the first CG configuration period can be selected, thereby saving CG configuration resources and reducing network device overhead. For services with small packet arrival intervals, the second CG configuration period can be selected to maintain the efficiency of uplink data transmission.

[0044] Based on the above solution, the first CG configuration period can be located in the period extension field. Thus, when a terminal device receives the first information containing the period extension field, it can transmit data packets according to the first CG configuration period. The first CG configuration period can match the period of actual data packet transmission, thereby saving CG configuration resources and reducing network device overhead.

[0050] In a third aspect, an embodiment of the present application provides a resource configuration device, which includes a module for implementing the first aspect or any possible implementation method of the first aspect.

[0051] In a fourth aspect, an embodiment of the present application provides a resource configuration device, which includes a module for implementing the second aspect or any possible implementation method of the second aspect.

[0052] In a fifth aspect, a communication device is provided, comprising a processor and a memory, wherein the processor is used to execute instructions stored in the memory so that the communication device executes the resource configuration method of the first aspect or any possible implementation of the first aspect, or so that the communication device executes the resource configuration method of the second aspect or any possible implementation of the second aspect.

[0053] In the sixth aspect, a computer program product comprising instructions is provided, which, when executed by a communication device, causes the communication device to execute the resource configuration method of the first aspect or any possible implementation of the first aspect, or causes the communication device to execute the resource configuration method of the second aspect or any possible implementation of the second aspect.

[0054] In the seventh aspect, a computer-readable storage medium is provided, comprising computer program instructions. When the computer program instructions are executed by a communication device, the communication device executes the resource configuration method of the first aspect or any possible implementation of the first aspect, or enables the communication device to execute the resource configuration method of the second aspect or any possible implementation of the second aspect.

[0055] In an eighth aspect, a communication method is provided, which is applied to a network device, and the method includes: receiving first information, and determining a first downlink channel bandwidth based on the first information; the first information is information about whether the terminal device supports the ability to receive a first downlink channel exceeding a first threshold bandwidth, and the first downlink channel is a multicast MBS physical downlink shared channel PDSCH without hybrid automatic repeat request (HARQ) feedback.

[0056] For example, the first information may be used to indicate that the terminal device supports receiving a first downlink channel with a bandwidth exceeding a first threshold. For another example, the first information may be used to indicate that the terminal device does not support receiving a first downlink channel with a bandwidth exceeding a first threshold.

[0057] Based on the above solution, the network device can configure different first downlink channel bandwidths based on different terminal capabilities to meet the needs of terminal devices with different capabilities. For example, when a terminal device supports receiving a first downlink channel with a bandwidth exceeding a first threshold, the network device configures a first downlink channel bandwidth exceeding the first threshold for the terminal device; when a terminal device does not support receiving a first downlink channel with a bandwidth exceeding the first threshold, the network device configures a first downlink channel bandwidth not exceeding the first threshold for the terminal device.

[0058] In combination with the eighth aspect, in certain implementations of the eighth aspect, the first threshold may be a preset value, for example, 5 MHz.

[0059] In one possible implementation, the first threshold is related to the subcarrier spacing. When the subcarrier spacing is 15 kHz, the first threshold is 25 resource blocks (RBs); when the subcarrier spacing is 30 kHz, the first threshold is 12 RBs.

[0060] In a ninth aspect, a communication method is provided, the method being applied to a terminal device, the method comprising: sending first information; and receiving a first downlink channel associated with the first information. The first information indicates whether the terminal device supports receiving the first downlink channel with a bandwidth exceeding a first threshold, the first downlink channel being a multicast MBS physical downlink shared channel (PDSCH) without HARQ feedback.

[0061] Based on the above solution, the terminal device can obtain the first downlink channel bandwidth of the corresponding bandwidth configured by the network device by reporting its capabilities. For example, when the terminal device reports that it supports the ability to receive bandwidth exceeding a first threshold, the network device configures a first downlink channel bandwidth exceeding the first threshold for the terminal device; when the terminal device reports that it does not support the ability to receive bandwidth exceeding the first threshold, the network device configures a first downlink channel bandwidth not exceeding the first threshold for the terminal device.

[0062] In combination with the ninth aspect, in certain implementations of the ninth aspect, the first threshold may be a preset value, for example, 5 MHz.

[0063] In one possible implementation, the first threshold is related to the subcarrier spacing. When the subcarrier spacing is 15 kHz, the first threshold is 25 RBs; when the subcarrier spacing is 30 kHz, the first threshold is 12 RBs. BRIEF DESCRIPTION OF THE DRAWINGS

If the fronthaul interface between the DU and the RU is a common public radio interface (CPRI), the DU is configured to implement one or more baseband functions, and the RU is configured to implement one or more radio frequency functions. If the fronthaul interface between the DU and the RU is another type of interface, relative to the CPRI, some of the downlink and / or uplink baseband functions, such as precoding, digital beamforming (BF), or one or more of inverse fast Fourier transform (IFFT) / cyclic prefix (CP) for downlink, are moved from the DU to the RU for implementation; and for uplink, one or more of digital beamforming (BF), or fast Fourier transform (FFT) / cyclic prefix (CP) removal, are moved from the DU to the RU for implementation. In one possible implementation, the interface may be an enhanced common public radio interface (eCPRI). In the eCPRI architecture, the division between the DU and RU is different, corresponding to different types (category, Cat) of eCPRI, such as eCPRI Cat A, B, C, D, E, and F.

[0088] Taking eCPRI Cat A as an example, for downlink transmission, based on layer mapping, the DU is configured to implement layer mapping and one or more functions preceding it (i.e., one or more of coding, rate matching, scrambling, modulation, and layer mapping), while other functions after layer mapping (e.g., RE mapping, BF, or one or more of IFFT / CP) are moved to the RU for implementation. For uplink transmission, based on de-RE mapping, the DU is configured to implement de-mapping and one or more functions preceding it (i.e., one or more of decoding, de-rate matching, descrambling, demodulation, inverse discrete Fourier transform (IDFT), channel equalization, and de-RE mapping), while other functions after de-mapping (e.g., one or more of digital BF or fast Fourier transform (FFT) / CP removal) are moved to the RU for implementation. It is understood that for the functional description of the DU and RU corresponding to various types of eCPRI, please refer to the eCPRI protocol and will not be repeated here.

[0089] In one possible design, the processing unit for implementing baseband functions in the BBU is called a baseband high layer (BBH) unit, and the processing unit for implementing baseband functions in the RRU / AAU / RRH is called a baseband low layer (BBL) unit.

[0090] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0091] In the embodiments of the present application, the device for implementing the functions of the network device can be a network device; it can also be a device that can support the network device to implement the functions, such as a chip system, a hardware circuit, a software module, or a hardware circuit and a software module. The device can be installed in the network device or used in conjunction with the network device. In the embodiments of the present application, only the device for implementing the functions of the network device is used as an example to illustrate, and does not constitute a limitation on the solutions of the embodiments of the present application.

[0092] The network device and / or terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on the water surface; it can also be deployed on aircraft, balloons and satellites in the air. The embodiments of this application do not limit the scenarios in which the network device and the terminal device are located. In addition, the terminal device and the network device can be hardware devices, or they can be software functions running on dedicated hardware, software functions running on general-purpose hardware, such as virtualization functions instantiated on a platform (e.g., a cloud platform), or entities including dedicated or general-purpose hardware devices and software functions. This application does not limit the specific forms of the terminal device and the network device.

[0093] In some wireless communication systems, a terminal device communicates wirelessly with a network device to send or receive electronic signals to or from the network device. These electronic signals may contain data or messages. Wireless communication from a terminal device to a network device is called uplink communication or uplink transmission. Wireless communication from a network device to a terminal device is called downlink communication or downlink transmission.

[0094] Resources are required to perform uplink and downlink communications. For example, a UE can wirelessly transmit data to a base station via uplink transmission at a specific frequency or within a specific time slot. The frequencies and time slots used are examples of resources (sometimes referred to as time-frequency resources).

[0095] Some wireless communication systems may support grant-based uplink transmissions. That is, if a terminal device wishes to send data to a network device, it first requests appropriate uplink resources from the network device. Once the network device grants the requested uplink resources, the terminal device uses the granted uplink resources to send uplink transmissions. For example, the uplink resources that the network device may grant may be a set of time-frequency locations within an uplink orthogonal frequency division multiple access (OFDMA) frame.

[0096] Some wireless communication systems may support configured grant (CG) uplink transmissions. This means that a terminal device can use certain uplink resources that may be shared with other terminal devices to send uplink transmissions without specifically requesting the use of these resources or requiring specific authorization from the network device. CG transmissions do not require dynamic and explicit scheduling authorization from the network device. CG transmissions are sometimes also called grant-free (GF) transmissions.

[0097] CG transmission can be configured via radio resource control (RRC) signaling messages. The RRC signaling message may include one or more parameters for one or more terminal devices to pre-configure the CG transmission, wherein the one or more parameters include one or more parameter sets. CG transmission has a certain period, which may be referred to as the CG configuration period. The CG configuration period is represented by the periodicity field in the ConfiguredGrantConfig information element (IE).

[0098] In CG transmission, the time-frequency resources of a physical uplink shared channel (PUSCH) can be called a transmission occasion (TO), and the TO is associated with the demodulation reference signal (DMRS) configured for CG PUSCH transmission.

[0099] Starting from the frame with system frame number (SFN) 0, each frame can be mapped to a synchronization signal / physical broadcast channel block (SSB) index, where the SSB index can distinguish different SSBs. Some SSB indexes can be mapped to valid TOs and associated DMRSs, and such SSB indexes are available, while unavailable SSB indexes cannot be mapped to valid TOs and associated DMRSs. For example, the CG configuration period can be 5ms. In one 5ms, the SSB indexes corresponding to all frames may be unavailable, so more 5ms periods are required. For example, the SSB beam corresponding to the available SSB index may have a specific direction, and there is no SSB beam with this specific direction in the first 5ms, so all SSB indexes in this 5ms are unavailable. If there is an SSB beam with this specific direction in the next 5ms, it means that there are available SSB indexes in these two 5ms, and the associated period is 2. That is to say, if there are available SSB indexes in N CG configuration periods, the associated period of the CG configuration period is N. Table 1 shows the mapping relationship between CG configuration period and association period.

[0100] Table 1

[0101] As can be seen from Table 1, currently, the maximum transmission period defined by the periodicity field is 640ms.

[0102] Some wireless communication systems are suitable for massive machine-type communications (mMTC). mMTC addresses the inadequacy of traditional mobile communications in supporting IoT and vertical industry applications, targeting low-power, high-connectivity scenarios. For example, mMTC is suitable for sensing and data collection applications such as smart cities, environmental monitoring, smart homes, and forest fire prevention. These applications require small data packets, low power consumption, and massive connections.

[0103] In mMTC scenarios, sporadic services often occur, and the interval between data packet arrivals is large, far exceeding 640ms. This means that the interval between data packet arrivals may far exceed the CG configuration period, resulting in a waste of CG configuration resources.

[0104] Therefore, how to reduce the waste of CG configuration resources is an urgent problem to be solved.

[0105] Figure 2 is a schematic flow chart of a resource configuration method 200 provided in an embodiment of the present application. Resource configuration method 200 can reduce the waste of CG configuration resources.

[0106] S210, the network device determines the first information, wherein the first information includes a first CG configuration period, and the maximum transmission period corresponding to the first CG configuration period is greater than 640ms.

[0107] This application does not limit the first information. For example, the first information may be the aforementioned ConfiguredGrantConfig, or other information.

[0108] Based on the above scheme, the maximum transmission period corresponding to the CG configuration period is greater than 640ms, so that when the data packet arrival interval is large (for example, the data packet arrival interval is greater than 640ms), the resource configuration method provided in the embodiment of the present application can enable the CG configuration period to match the actual data transmission period, thereby saving CG configuration resources.

[0109] In some embodiments, the maximum transmission period corresponding to the first CG configuration period includes any one of 1280ms, 2560ms, 5120ms, 10240ms, 20480ms, 40960ms, 81920ms, 163840ms, 327680ms, 655360ms, 1310720ms, 2621440ms and 5242880ms.

[0110] However, this application does not limit the maximum transmission period corresponding to the first CG configuration period to only the above values. For example, it can also be 1000ms, 10000000ms, etc.

[0111] When the maximum transmission period corresponding to the first CG configuration period is 81920ms, it can match minute-level services. When the maximum transmission period corresponding to the first CG configuration period is 5242880ms, it can match hour-level services.

[0112] In some embodiments, the transmission period included in the first CG configuration period is 1280ms, 2560ms, 5120ms, 10240ms, 20480ms, 40960ms, and 81920ms. Under this parameter set, the maximum minute-level service can be matched.

[0113] In other embodiments, the transmission period included in the first CG configuration period is 1280ms, 2560ms, 5120ms, 10240ms, 20480ms, 40960ms, 81920ms, 163840ms, 327680ms, 655360ms, 1310720ms, 2621440ms, and 5242880ms. Under this parameter set, the maximum service level can be matched, while the minute-level and second-level services can also be matched.

[0114] In some other embodiments, the transmission period included in the first CG configuration period is 81920ms, 163840ms, 327680ms, 655360ms, 1310720ms, 2621440ms, and 5242880ms. Under this parameter set, only minute-level and hour-level services can be matched.

[0115] Based on the above scheme, the maximum transmission period corresponding to the CG configuration period is greater than 640ms, and there are multiple options, so that when the interval between data packet arrivals is large, the CG configuration period can match the service transmission period of seconds, minutes or hours, thereby saving CG configuration resources.

[0116] In some embodiments, determining the first information includes: determining the first CG configuration period according to the load of the network device. In other words, the first CG configuration period is related to the load of the network device.

[0117] Based on the above solution, network devices can determine the CG configuration period based on load conditions. For example, when the network load is high, the CG configuration period can be longer, and when the load is light, the CG configuration period can be shorter, thereby improving network utilization and reducing the failure rate of the communication system.

[0118] S220: The network device sends the first information to the terminal device. Correspondingly, the terminal device receives the first information from the network device.

[0119] In some embodiments, the network device sending the first information to the terminal device includes: the network device sending radio resource control (RRC) signaling, wherein the RRC signaling carries the first information, and the first information further includes a period extension field, wherein the period extension field includes the first CG configuration period. Correspondingly, the terminal device receiving the first information from the network device includes: the terminal device receiving the radio resource control (RRC) signaling.

[0120] For example, the period extension field may be "cg-SDT-PeriodicityExt-r18". The period extension field includes the CG configuration period. For example, in ConfiguredGrantConfig, the period extension field of "cg-SDT-PeriodicityExt-r18" may be included.

[0121] In some embodiments, the value of the period extension field can be 1280ms, 2560ms, 5120ms, 10240ms, 20480ms, 40960ms, or 81920ms. Under this parameter set, a maximum of minute-level services can be matched.

[0122] In other embodiments, the value of the period extension field may be 1280ms, 2560ms, 5120ms, 10240ms, 20480ms, 40960ms, 81920ms, 163840ms, 327680ms, 655360ms, 1310720ms, 2621440ms, or 5242880ms. Under this parameter set, hourly services can be matched at most, while minute-level and second-level services can also be matched.

[0123] In some other embodiments, the value of the period extension field may be 81920ms, 163840ms, 327680ms, 655360ms, 1310720ms, 2621440ms, or 5242880ms. Under this parameter set, only minute-level and hour-level services can be matched.

[0124] Based on the above solution, the first CG configuration period can be located in the period extension field. Thus, when a terminal device receives the first information containing the period extension field, it can transmit data packets according to the first CG configuration period. The first CG configuration period can match the period of actual data packet transmission, thereby saving CG configuration resources and reducing network device overhead.

[0125] S230: The terminal device sends a data packet to the network device according to the first information. Correspondingly, the network device receives the data packet from the terminal device.

[0126] In some embodiments, sending a data packet to the network device according to the first information includes sending a data packet of a CG-small data transmission (SDT) service to the network device according to the first information. In other words, the terminal device is capable of supporting the CG-SDT service.

[0127] It should be understood that the CG-SDT service also includes the extended CG-SDT service, which is a service with an arrival interval much larger than 640 ms, such as a service that arrives every few minutes or hours.

[0128] However, this application does not limit the specific form of the data packet. For example, it can also be a data packet of other services.

[0129] The CG-SDT service can be understood as a small packet transmission service based on pre-configured resources. In the resource configuration method provided in the embodiment of the present application, the terminal device supports the CG-SDT service, which can reduce power consumption, reduce signaling overhead, improve network efficiency and reduce latency.

[0130] In some embodiments, sending a data packet for a CG-SDT service to a network device based on the first information includes: determining a time domain symbol position corresponding to the data packet for the CG-SDT service based on the first CG configuration period and a system superframe number; and sending the data packet for the CG-SDT service to the network device based on the time domain symbol position. That is, in some embodiments, the time domain symbol position corresponding to the CG-SDT service is related to the first CG configuration period and the system superframe number.

[0131] In other words, the superframe can be used as the maximum time domain granularity to determine the time domain symbol position of the PUSCH. It should be noted that the service of the data packet determined by the system superframe number is not limited to the CG-SDT service, but can also be other services, such as large packet transmission services.

[0132] Superframe, radio frame, time slot, and symbol are parameters in the time domain. A superframe can contain up to 1024 radio frames, each of which can be 10 ms long. When the subcarrier spacing is 15 kHz, a radio frame consists of 10 time slots. Each time slot can contain 14 symbols.

[0133] Exemplarily, the time-domain symbol position can be determined by Formula 1.

[0134] Time domain symbol position = superframe position + radio frame position + time slot position + symbol position (Formula 1)

[0135] For example, Formula 1 can be expressed in the form of Formula 2.

[0136] Time Domain Symbol Position = (HSFN × numberOfFramesPerHyperframe × numberOfSlotsPerFrame × numberOfSymbolsPerSlot) + (SFN × numberOfSlotsPerFrame × numberOfSymbolsPerSlot) + (slot number in the frame × numberOfSymbolsPerSlot) + symbol number in the slot (Formula 2)

[0137] HSFN represents the system hyperframe number. The number of radio frames per hyperframe (numberOfFramesPerHyperframe) may refer to the number of radio frames in each hyperframe, for example, 1024. The number of slots per radio frame (numberOfSlotsPerFrame) may refer to the number of slots in each radio frame, for example, 10. The number of symbols per slot (numberOfSymbolsPerSlot) may refer to the number of symbols in each slot, for example, 14. The slot number (slot number in the frame) may refer to the sequence number of the slot in the radio frame.

[0138] The first term in Formula 2 represents the superframe duration, the second term represents the radio frame duration, the third term represents the slot duration, and the fourth term represents the symbol duration. The above "duration" is in symbols.

[0139] For example, during the Nth uplink authorization, Formula 1 can also be expressed in the form of Formula 3.

[0140] Time Domain Symbol Position = (timeReferenceHSFN×numberOfFramesPerHyperframe×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+timeReferenceSFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+timeDomainOffset×numberOfSymbolsPerSlot+S+N×cg-SDT-PeriodicityExt-r18) modulo(1024×1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot) (Formula 3)

[0141] Among them, time reference HSFN (timereferenceHSFN) represents the system superframe number based on the preset time reference, time reference SFN (timereferenceSFN) represents the system frame number based on the preset time reference, time domain offset (timeDomainOffset) represents the time slot number based on the preset time reference, and S can be the position of the starting symbol in a time slot. "cg-SDT-PeriodicityExt-r18" represents the number of symbols in a CG configuration period, and N is greater than or equal to 0. For other parameters, please refer to the description of Formula 2 and are not repeated here.

[0142] When the system runs for more than 1024 superframes, the remainder of the current number of symbols relative to 1024 superframes can be determined according to the modulo function in Formula 3, thereby reducing the computational overhead of the system.

[0143] For sporadic services, the actual data transmission cycle may be several minutes or even hours. The resource configuration method provided in the embodiment of the present application introduces a superframe, which can support a larger CG configuration cycle. Compared with the solution that determines the time domain symbol position only by the number of wireless frames, the number of time slots and the number of symbols, the resource configuration method provided in the embodiment of the present application is expanded from 1024 wireless frames to 1024 superframes, an increase of 1024 times, so that the CG configuration cycle can match the hourly service transmission cycle, thereby saving CG configuration resources and reducing the overhead of network equipment.

[0144] In some embodiments, the method 200 further includes: the network device sending second information to the terminal device, wherein the second information includes a second CG configuration period, and the second CG configuration period is less than the first CG configuration period. Correspondingly, the method 200 further includes: receiving the second information from the network device.

[0145] The second information can be carried in the same signaling as the first information, or in different signalings, which is not limited in this application. The second information can be sent simultaneously with the first information, or at different times, which is not limited in this application.

[0146] For example, the maximum transmission period corresponding to the second CG configuration period can be 640ms.

[0147] Based on the above solution, network devices can be configured with different CG configuration periods, allowing terminal devices to flexibly select according to service needs. For example, for services with large packet arrival intervals, the first CG configuration period can be selected, thereby saving CG configuration resources and reducing network device overhead. For services with small packet arrival intervals, the second CG configuration period can be selected to maintain the efficiency of uplink data transmission.

[0148] In some embodiments, the first CG configuration period and the second CG configuration period are carried in RRC signaling, the RRC signaling includes a period field and a period extension field, and the period field includes the second CG configuration period.

[0149] In other words, both the first information and the second information can be carried in RRC signaling. For example, the "periodicity" field in ConfiguredGrantConfig can be used as the period field, and the "periodicity" field can include the second CG configuration period. In addition, "cg-SDT-PeriodicityExt-r18" is used as the extension field, and "cg-SDT-PeriodicityExt-r18" can include the first CG configuration period.

[0150] Based on the above solution, network devices can configure different CG configuration periods in RRC signaling, allowing terminal devices to flexibly select according to service needs. For example, for services with large data packet arrival intervals, the first CG configuration period can be selected, thereby saving CG configuration resources and reducing network device overhead. For example, for services with small data packet arrival intervals, the second CG configuration period can be selected, thereby not reducing the transmission efficiency of uplink data.

[0151] In some embodiments, the period extension field is used for the first type of terminal device to determine the CG configuration period, and the period field is used for the second type of terminal device to determine the CG configuration period.

[0152] For example, the first type of terminal devices may include NR reduced capability (RedCap) terminal devices, and the second type of terminal devices may include legacy terminal devices (e.g., NR Rel-15 terminal devices, Rel-16 terminal devices, etc.). NR RedCap terminal devices have lower data transmission capabilities or costs than legacy terminal devices. For example, NR RedCap terminal devices may include industrial sensors, security cameras, smart grid-related equipment, high-end wearable devices, and high-end logistics tracking devices.

[0153] It should be noted that NR RedCap terminal devices can also be described using other terms, and terminal devices with the same or similar capabilities as NR RedCap terminal devices also fall within the scope of NR RedCap terminal devices.

[0154] In some embodiments, the difference between the first type of terminal device and the second type of terminal device includes at least one of the following:

[0155] (1) Different bandwidth capabilities. For example, a Type II terminal device can support simultaneous use of a 100 MHz frequency resource on a single carrier for data transmission with a network device; whereas a Type I terminal device can support simultaneous use of a 20 MHz, 10 MHz, or 5 MHz frequency resource on a single carrier for data transmission with a network device.

[0156] (2) The number of transmit and receive antennas is different. For example, the minimum antenna configuration supported by the second type of terminal device is 4 transmit and 2 receive antennas. That is, in the minimum antenna configuration, 4 receive antennas are used to receive downlink data, and 2 transmit antennas are used to send uplink data. The maximum antenna configuration supported by the first type of terminal device can be less than 4 transmit and 2 receive antennas. For example, the first type of UE only supports 2 receive and 1 transmit, or can also support 2 receive and 2 transmit.

[0157] (3) Different uplink maximum transmit powers. For example, the uplink maximum transmit power of the second type of terminal device may be 23dBm or 26dBm, while the uplink maximum transmit power of the first type of terminal device may be a value between 4dBm and 20dBm.

[0158] (4) The protocol versions corresponding to the first type of terminal devices and the second type of terminal devices are different. For example, NR Rel-15 and NR Rel-16 terminal devices can be considered as second type of terminal devices; and first type of terminal devices can be considered as NR Rel-17 and NR Rel-18 terminal devices.

[0159] (5) Different carrier aggregation (CA) capabilities. For example, the second type of terminal device can support carrier aggregation, while the first type of terminal device does not support carrier aggregation. For another example, both the first type and the second type of terminal device support carrier aggregation, but the maximum number of carrier aggregations supported simultaneously by the second type of terminal device is greater than the maximum number of carrier aggregations supported simultaneously by the first type of terminal device. For example, the second type of terminal device can support aggregation of up to 5 carriers or 32 carriers simultaneously, while the first type of terminal device can support aggregation of up to 2 carriers simultaneously.

[0160] (6) The second type of terminal equipment supports full-duplex FDD, while the first type of terminal equipment only supports half-duplex FDD.

[0161] (7) The first type terminal device and the second type terminal device have different data processing delays. For example, the minimum delay between the second type terminal device receiving downlink data and sending feedback on the downlink data is less than the minimum delay between the first type terminal device receiving downlink data and sending feedback on the downlink data, and / or the minimum delay between the second type terminal device sending uplink data and receiving feedback on the uplink data is less than the minimum delay between the first type terminal device sending uplink data and receiving feedback on the uplink data.

[0162] (8) The uplink and / or downlink transmission peak rates and processing capabilities corresponding to the first type of terminal device and the second type of terminal device are different. The transmission peak rate and processing capability of the first type of terminal device are lower than the transmission peak rate and processing capability of the second type of terminal device.

[0163] Based on the above scheme, the resource configuration method provided in the embodiment of the present application can configure different CG configuration periods for multiple types of terminal devices. Among them, the CG configuration period of the first type of terminal device is greater than the CG configuration period of the second type of terminal device. The capability of the first type of terminal device is relatively low, and the data packet arrival interval is large, while the capability of the second type of terminal device is relatively high, and the data packet arrival interval is small. Therefore, the CG configuration period of each type of terminal device can respectively match the actual data transmission period of the terminal device of that type, thereby saving CG configuration resources for the first type of terminal device. For the second type of terminal device, sufficient CG configuration resources are configured without reducing the transmission efficiency of uplink data.

[0164] In some embodiments, the association period corresponding to the first CG configuration period is 1, and there is at least one SSB index mapped to a valid transmission opportunity in the association period.

[0165] The SSB period must be considered when determining the association period. The association period is related to the maximum SSB period and the number of SSBs contained in an SSB burst.

[0166] Figure 3 is a schematic diagram of a synchronization signal block provided in an embodiment of the present application. Referring to Figure 3, the maximum period of the SSB can be configured to 160ms. In the sub3G frequency range, the number of SSBs contained in an SSB burst is 4. SSB beams in different directions are sent sequentially at intervals of 160ms, and at least one repeated beam will appear after 640ms. Therefore, there will be an available SSB index in an association period of at most 640ms. When the transmission period corresponding to the first CG configuration period is greater than or equal to 640ms, the association period corresponding to each first CG configuration period is 1, and it can always be guaranteed that there is an available SSB index in an association period. That is, when the first CG configuration period is 1280ms, 2560ms, 5120ms, 10240ms, 20480ms, 40960ms, 81920ms, 163840ms, 327680ms, 655360ms, 1310720ms, 2621440ms and 5242880ms, the associated period is 1. In other words, when the first CG configuration period is 1280ms, the association period is 1; when the first CG configuration period is 2560ms, the association period is 1; when the first CG configuration period is 5120ms, the association period is 1; when the first CG configuration period is 10240ms, the association period is 1; when the first CG configuration period is 20480ms, the association period is 1; when the first CG configuration period is 40960ms, the association period is 1; when the first CG configuration period is 81920ms, the association period is 1; when the first CG configuration period is 163840ms, the association period is 1; when the first CG configuration period is 327680ms, the association period is 1; when the first CG configuration period is 655360ms, the association period is 1; when the first CG configuration period is 1310720ms, the association period is 1; when the first CG configuration period is 2621440ms, the association period is 1; when the first CG configuration period is 5242880ms, the association period is 1. Table 2 shows the mapping relationship between the first CG configuration period and the associated period. For the purpose of distinction, the CG configuration period shown in Table 1 can be regarded as the second CG configuration period, that is, the mapping relationship shown in Table 1 can be regarded as the mapping relationship between the second CG configuration period and the associated period.

[0167] Table 2

[0168] In one possible example, the maximum period of the SSB can be configured to be 160ms, and the number of SSBs contained in an SSB burst is 8. There will be an available SSB index within an association period of at most 1280ms. When the transmission period corresponding to the first CG configuration period is greater than or equal to 1280ms, the association period corresponding to each first CG configuration period is 1, and it can always be guaranteed that there is an available SSB index within an association period. In other words, the mapping relationship between the first CG configuration period and the association period can still be found in Table 2. The mapping relationship between the second CG configuration period and the association period can be found in Table 3 below.

[0169] Table 3

[0170] In another possible example, the maximum period of the SSB can be configured to be 160ms, and the number of SSBs contained in an SSB burst is 16. There will be an available SSB index in an association period of at most 2560ms. When the transmission period corresponding to the first CG configuration period is greater than or equal to 2560ms, the association period corresponding to each first CG configuration period is 1, and it can always be guaranteed that there is an available SSB index in an association period. When the transmission period corresponding to the first CG configuration period is equal to 1280ms, the association period corresponding to the first CG configuration period is 1 or 2. That is to say, the mapping relationship between the first CG configuration period and the association period can be seen in Table 4 below. The mapping relationship between the second CG configuration period and the association period can be seen in Table 5 below.

[0171] Table 4

[0172] Table 5

[0173] In some embodiments, when the RRC signaling includes the period extension field cg-SDT-PeriodicityExt-r18 of the CG-SDT service, the terminal device determines the associated period according to the mapping relationship shown in Table 2, Table 4 or similar mapping tables; when the RRC signaling does not include the above-mentioned period extension field, the terminal device uses the period field periodicity to transmit the CG-SDT service, and determines the associated period according to the mapping relationship shown in Table 1, Table 3, Table 5 or similar mapping tables.

[0174] In some embodiments, the terminal device may also select different configuration period parameter sets according to different capabilities. When the terminal device has the ability to support CG-SDT services, it may select the mapping method shown in Table 2, Table 4 or similar mapping tables according to the CG-SDT period extension field; otherwise, it may select the mapping method shown in Table 1, Table 3, Table 5 or similar mapping tables according to the period field. Alternatively, when the terminal device has the ability to support reduced capabilities, it may select the mapping method shown in Table 2, Table 4 or similar mapping tables according to the CG-SDT period extension field; otherwise, it may select the mapping method shown in Table 1, Table 3, Table 5 or similar mapping tables according to the period field. Possible reduced capabilities include at least one of the following: a maximum bandwidth of 20MHz; a peak rate of 10Mbps. However, this application is not limited to this. For example, when the terminal device has the ability to support other capabilities, it may also select the mapping method shown in Table 2, Table 4 or similar mapping tables according to the CG-SDT period extension field.

[0175] In some embodiments, the terminal device can also determine the association period corresponding to different fields according to different capabilities. When the terminal device has the ability to support CG-SDT services, the association period can be determined to be 1 according to the CG-SDT period extension field; otherwise, the association period is determined according to the period field. Alternatively, when the terminal device has the ability to support reduced capabilities, the mapping method shown in Table 2, Table 4 or similar mapping tables can be selected according to the CG-SDT period extension field; otherwise, the mapping method shown in Table 1, Table 3, Table 5 or similar mapping tables can be selected according to the period field. Possible reduced capabilities include at least one of the following: a maximum bandwidth of 20MHz; a peak rate of 10Mbps. However, this application is not limited to this. For example, when the terminal device has the ability to support other capabilities, the association period can also be determined to be 1 according to the CG-SDT period extension field.

[0176] The above-mentioned "according to the CG-SDT period extension field" means that when the CG-SDT period extension field exists, processing is performed based on the CG-SDT period extension field.
