Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a method and apparatus for reporting capability information. Background Technology

[0002] Carrier aggregation (CA) is a technology that increases transmission bandwidth. It has been introduced in Long Term Evolution (LTE), Long Term Evolution-Advanced (LET-A), and New Radio (NR) systems, enabling a terminal device to transmit data on multiple carriers simultaneously.

[0003] In existing technologies, UE capability information is determined based on the number of carriers supported by the user equipment (UE) and the maximum supported channel bandwidth on each carrier. The capabilities of each carrier are independent, resulting in significant redundancy in the UE design. In carrier aggregation scenarios, when reporting carrier aggregation capability information, the UE, according to existing protocols, designs the corresponding processing capabilities based on the maximum supported bandwidth of each carrier within the band (in carrier aggregation, the carriers participating in the aggregation are also called component carriers (CCs)) and reports this processing capability information. However, in actual data transmission, the bandwidth scheduled for a single carrier often does not reach the maximum supported bandwidth of the component carriers. This leads to unnecessary waste of UE capabilities and increases the UE's design cost. Summary of the Invention

[0004] This application provides a capability information reporting method that can be applied to communication systems, such as Long Term Evolution (LTE), New Radio (NR), Evolved Universal Terrestrial Radio Access and New Radio Dual Connectivity (E-UTRA-NR dual connectivity, EN DC), Ultra Reliability Low Latency Communication (URLLC), Vehicle to Everything (V2X), LTE-V, NR-V, Vehicle-to-Vehicle (NR-V), Vehicle-to-Vehicle (V2V), Internet of Vehicles (IoV), Massive Machine Type Communication (mMTC), Internet of Things (IoT), LTE-Machine to Machine (LTE-M), Machine to Machine (M2M), Device to Device (D2D), etc. The method provided in this application embodiment is used to schedule resources reasonably based on the maximum aggregated spectrum capability information contained in the capability information when the scheduled node sends capability information to the scheduling node, thereby reducing the waste of terminal device capability and reducing the cost of terminal device.

[0005] In a first aspect, embodiments of this application provide a capability information reporting method, the method comprising: a first device determining capability information of the first device, the capability information of the first device indicating the capability of the first device to support the maximum aggregated spectrum within a first range; and the first device sending the capability information to a second device.

[0006] In this application, when the first device reports capability information to the second device, a novel capability information reporting method is provided by carrying capability information of the maximum aggregated spectrum supported by the first device within a first range in the capability information. This novel capability information reporting method avoids the need for the first device to report according to the maximum bandwidth corresponding to each component carrier supported by the first device. Therefore, when designing the capabilities supported by the first device, it is not necessary to design according to the maximum bandwidth corresponding to each component carrier, reducing the design cost of the first device, reducing the waste of terminal device capabilities, and making scheduling resources more reasonable.

[0007] Alternatively, in one possible implementation, the maximum aggregated spectrum is less than the first bandwidth, which is the sum of the maximum bandwidths of all aggregated carriers supported by the first device within a first range.

[0008] In the method provided in this application embodiment, the maximum aggregated spectrum supported by the first device is less than the sum of the maximum bandwidths of all aggregated carriers within the first range. This avoids the need to design the capabilities supported by the first device according to the maximum bandwidth for all aggregated carriers. Furthermore, the larger the capability supported by the first device, the higher the corresponding cost. Therefore, by reporting the capability information using the method provided in this application embodiment, excessive capabilities can be avoided during the design phase of the first device, which is beneficial for reducing the cost of the first device.

[0009] Optionally, in one possible implementation, the capability information further includes first indication information, which indicates a first range supported by the first device.

[0010] In this application, when the capability information also includes indication information for indicating the first range supported by the first device, the terminal device can determine the first range according to different application scenarios and / or costs and / or functions, thereby having better implementation flexibility.

[0011] Optionally, in one possible implementation, the capability information further includes second indication information, which indicates the minimum guaranteed bandwidth of the carrier within the supported first range of the first device.

[0012] In this application, when the capability information includes the minimum guaranteed bandwidth of at least one carrier within the first supported range of the first device, the second device can reserve the minimum guaranteed bandwidth for at least one carrier when scheduling resources according to the capability information, and the basic communication function of at least one carrier can be guaranteed when the terminal capabilities are shared.

[0013] Optionally, in one possible implementation, the capability information further includes third indication information, which is used to instruct the first device to support the first device in scheduling multiple resource units within a first range, wherein the sum of the multiple resource units is less than or equal to the maximum aggregated spectrum.

[0014] In this application, when the capability information also includes third indication information for instructing the first device to support the first device in scheduling multiple resource units within a first range, the feasibility of the solution is increased, and the implementation complexity caused by the resource units being too small is avoided.

[0015] Alternatively, in one possible implementation, at least one of the carriers supported by the first device within a first range includes non-contiguous resource elements.

[0016] In this application, when the first device supports scheduling carriers of discontinuous resource units, frequency diversity gain can be used to improve the efficiency of spectrum resource utilization.

[0017] Optionally, in one possible implementation, after the first device sends the capability information, the first device receives first scheduling information sent by the second device. The first scheduling information is used to determine a first frequency domain resource within a first range. The first frequency domain resource is used for data transmission of the first device. The first frequency domain resource is less than or equal to the maximum aggregated spectrum supported by the first device within the first range.

[0018] In this application, the first device transmits data through the first frequency domain resources scheduled by the second device. The first frequency domain resources are less than or equal to the maximum aggregated spectrum supported by the first device within a first range, so as to avoid exceeding the processing capacity of the first device and improve the feasibility of the solution.

[0019] Optionally, in one possible implementation, after receiving the first scheduling information, the first device determines the first frequency domain resource based on the first scheduling information. After determining the first frequency domain resource, the first device then determines the spectrum processing resource of the first device based on the first frequency domain resource. The spectrum processing resource includes the processing resource used by the first device when receiving data carried on the first frequency domain resource, and / or the processing resource used by the first device when sending data carried on the first frequency domain resource.

[0020] In this application, the first device determines the spectrum processing resources of the first device based on the first frequency domain resources, thereby avoiding the increase in power consumption caused by using too many spectrum processing resources and improving the efficiency of the solution.

[0021] Optionally, in one possible implementation, after sending the capability information, the first device also sends a fourth indication message to the second device, which is used to indicate that the capability information of the first device should be updated.

[0022] In this application, the first device improves the flexibility of the solution by sending an instruction to the second device to update the capability information.

[0023] Optionally, in one possible implementation, the capability information includes a scaling factor used to determine the maximum aggregated spectrum.

[0024] This application illustrates that the capability information may also include a scaling factor, without needing to send the specific value of the capability information, such as the value of the maximum aggregated spectrum, thus saving bandwidth when sending the capability information.

[0025] Optionally, in one possible implementation, the received spectrum processing resources include at least one of the following: radio frequency processing resources, front-end processing resources, channel estimation processing resources, demodulation processing resources, decoding processing resources, decryption processing resources, measurement processing resources, etc. For the channel estimation processing resources, at least one of the following may be included: channel estimation and demodulation resources for the Physical Downlink Control Channel (PDCCH), channel estimation resources for the Physical Downlink Shared Channel (PDSCH), channel estimation and demodulation resources for the Physical Sidelink Control Channel (PSCCH), and channel estimation resources for the Physical Sidelink Data Channel (PSDCH).

The decoding processing resources may include polar code decoding units and / or low-density parity-check code (LDPC) decoding units. The first device may determine that the received spectrum processing resources include one or more of the aforementioned processing resources based on at least one factor such as application scenario, requirements, functional requirements, and cost.

[0026] This application describes the information that the received processing resources may include, improving the feasibility of the solution. The first device can determine the processing resources included in the received spectrum processing resources, thus improving the flexibility of the solution.

[0027] Optionally, in one possible implementation, the transmit spectrum processing resources may include at least one of the following: radio frequency processing resources, power amplifier processing resources, front-end processing resources, encryption processing resources, data packet assembly processing resources, coding processing resources, modulation processing resources, transmit power control processing resources, etc. It is understood that other resources may also be included, such as resources required for processing various channels, such as Physical Uplink Shared Channel (PUSCH) channel processing resources, Physical Uplink Control Channel (PUCCH) channel processing resources, Physical Sidelink Control Channel (PSCCH) channel processing resources, Physical Sidelink Data Channel (PSDCH) channel processing resources, etc. The first device may determine that the transmit spectrum processing resources include one or more of the aforementioned processing resources based on at least one factor such as application scenario, requirements, functional requirements, and cost.

[0039] Optionally, in one possible implementation, the first device sends capability information to the second device by means of capability information reporting.

[0040] This application describes how the first device can send its capability information through capability information reporting, thereby improving the feasibility of the solution.

[0041] Optionally, in one possible implementation, the capability information includes the value of the maximum aggregate spectrum.

[0042] This application specifies that the capability information includes the value of the maximum aggregated spectrum, which improves the feasibility of the solution.

[0043] Optionally, in one possible implementation, after receiving the first frequency domain resource, the first device determines whether the first frequency domain resource is less than the maximum aggregated spectrum within the first range supported by the first device. If the first frequency domain resource is greater than the maximum aggregated spectrum within the first range supported by the first device, the first device determines that the scheduling of the second device has failed and sends an error message to the second device.

[0044] In this application, when the first frequency domain resource exceeds the maximum aggregated spectrum supported by the first device, the first device sends an error message to the second device, thereby improving the fault tolerance of the solution.

[0045] Optionally, in one possible implementation, the first device determines the first range based on the frequency band range that the first device's components can support, and the first device's components may include any of the following: an antenna, a radio frequency device, or a baseband processor.

[0046] In this application, the first device determines the first range based on the frequency band range that the first device's devices can support, thereby improving the feasibility of the solution.

[0047] The second aspect of this application provides a method for reporting capability information.

[0048] The second device receives capability information sent by the first device, which is used to indicate the maximum aggregated spectrum supported by the first device within a first range.

[0049] In this application, the second device receives capability information sent by the first device, and the capability information indicates the maximum aggregated spectrum supported by the first device. This allows the second device to determine the resources scheduled for the first device based on the capabilities of the first device, thus avoiding system errors.

[0050] Alternatively, in one possible implementation, the maximum aggregated spectrum is less than the first bandwidth, where the first bandwidth represents the sum of the maximum bandwidths of all aggregated carriers supported by the first device within a first range.

[0051] In this application, the maximum aggregated spectrum supported by the first device is less than the sum of the maximum bandwidths of all aggregated carriers within the first range. This avoids the need to design the capabilities supported by the first device based on the maximum bandwidth for all aggregated carriers. Furthermore, the greater the capability supported by the first device, the higher the corresponding cost. Therefore, by reporting the capability information using the method provided in this application, excessive capabilities can be avoided during the design phase of the first device, thus reducing its cost.

[0137] To facilitate understanding of the embodiments of this application, the terminology involved in this application will be introduced first.

[0138] Carrier: Unless otherwise specified, in the embodiments of this application, a carrier refers to a continuous segment of spectrum in the frequency domain. For example, under the 3GPP NR protocol, a carrier is equivalent to a carrier or component carrier (CC) defined in 3GPP NR. A carrier can also refer to a bandwidth part (BWP), a cell, a channel, a sub-channel, one or more resource blocks (RBs), or a resource block group (RBG). This resource block group can be physically continuous, such as a physical resource lock (PRB), or physically discontinuous but mapped to virtual continuous resources through certain mapping rules, such as a virtual resource block (VRB). For the embodiments provided in this application, the different names for various continuous segments of spectrum in the frequency domain, such as component carrier, BWP, resource block, resource block group, channel, and sub-channel, have the same implementation effect. For ease of description, they will not be repeated.

[0139] Data transmission: Data transmission includes sending and / or receiving data.

[0140] Carrier activation: Unless otherwise specified, carrier activation in this embodiment refers to the carrier (including various names for a continuous spectrum in the frequency domain such as carrier, component carrier, BWP, resource block, resource block group, channel, subchannel, etc.) being determined to be in a working state by both the first device and the second device. This working state can be one or more of being configured, activated, or enabled. Specifically, carrier activation includes:

[0141] Carrier configuration: The second device notifies the first device of the carrier configuration information (including bandwidth, center frequency, etc.) via higher-layer signaling (such as radio resource control messages).

[0142] Carrier activation: The second device notifies the terminal device to activate the carrier through one of the higher-layer signaling, media access control (MAC) signaling, or physical layer signaling. Activation can also be referred to as being enabled.

[0143] Unless otherwise specified, for ease of description, this application embodiment uses carrier activation as an example of carrier configuration.

[0144] Spectrum processing resources: The spectrum processing resources mentioned in the embodiments of this application refer to the processing resources of the terminal device required by the terminal device to process the spectrum, such as the processing resources in the central processing unit of the terminal device. It can be understood that the spectrum processing resources may also include other processing resources in the terminal device, such as memory resources, etc., which are not specifically limited here.

[0145] Carrier aggregation: Carrier aggregation as described in this application refers to the terminal device supporting the simultaneous scheduling or processing of more than one carrier, and is not limited to a single radio access technology. Here, a carrier is also called a component carrier (CC). For example, these carriers can support the same radio access technology (RAT), such as all carriers supporting NR radio access technology; or they can support different RATs, such as one LTE carrier and one NR carrier; multiple carriers can belong to the same cell group (CG) or different CGs, such as one carrier in the primary CG and one in the secondary CG; multiple carriers can belong to the same frequency band or different frequency bands; multiple carriers can be used for communication within one connection or for communication between different connections, such as multi-radio dual connectivity (MR-DC), where one carrier is used for LTE communication and another for NR communication; multiple carriers can be used for communication on the same link or for communication on different links, such as one carrier for a cellular link (Uulink) and one carrier for a sidelink; multiple carriers can be used for communication of the same type of service or for communication of different services, such as one carrier for enhanced mobile bandwidth access (EMB). Broadband (eMBB) services can be used in multiple ways: one carrier for vehicle-to-everything (V2X) services, one carrier for high-reliability low-latency communication (HRLC) services, one carrier for massive internet of things (mIoT) services; or one carrier for eMBB and URLLC services, one carrier for V2X services, and so on.

[0146] To better understand the capability information reporting method disclosed in the embodiments of this application, the communication system to which the embodiments of this application are applicable is described below.

[0147] Please see Figure 1 , Figure 1 This application provides a schematic diagram of the architecture of a communication system according to an embodiment. The communication system may include, but is not limited to, a network device and a terminal device. Figure 1The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this application. In actual applications, it may include two or more network devices and two or more terminal devices. Figure 1 The communication system shown is illustrated using an example comprising a network device 102 and multiple terminal devices 101.

[0148] It should be noted that the technical solutions of this application embodiment can be applied to various communication systems. For example, LTE systems, 5th generation (5G) mobile communication systems, 5G NR systems, or other future new mobile communication systems. The communication system can also be a communication system supporting multiple wireless technologies, such as a communication system supporting LTE and NR; or, the communication system can be a communication system supporting short-range communication, such as a communication system supporting sidelink (SL) technology, a communication system supporting wireless fidelity (WiFi) technology, etc. It should also be noted that the sidelink in this application embodiment can also be called a side link or a direct link.

[0149] The network device 102 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 102 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a transmission reception point (TRP), a relay node (RN), an access point (AP), a base station in other future mobile communication systems, or an access node in a WiFi system. This embodiment does not limit the specific technology or device form used in the network device.

[0150] The terminal device 101 in this application embodiment is a user-side entity used to receive or transmit signals, such as a mobile phone. Terminal devices can also be called terminals, user equipment (UE), mobile stations (MS), mobile terminals (MT), etc. Terminal devices can be communication-enabled vehicles, smart cars, mobile phones, wearable devices, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc. The embodiments of this application do not limit the specific technology or device form used in the terminal device.

[0151] exist Figure 1 In one optional implementation of the communication system, the terminal device 101 reports its own capability information to the network device 102, and the network device 102 performs resource scheduling based on the capability information reported by the terminal device 101, and then communicates with the terminal device 101.

[0152] In another optional implementation, terminal device 101 has a scheduling function. During direct communication between terminal device 101 and other terminal devices, terminal device 101 receives capability information sent by other terminal devices. Based on this capability information, terminal device 101 determines the resources that need to be scheduled and communicates with other terminal devices accordingly. Direct communication between terminal device 101 and other terminal devices means that when terminal device 101 transmits information to other terminal devices, it does not need to go through network device 102 for information forwarding, but can directly exchange information. Examples include vehicle-to-everything (V2X) communication systems and machine-to-machine (M2M) communication systems.

[0153] The capability information reporting method and apparatus provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0154] In this embodiment of the application, after the first device reports the capability information, the corresponding capability information may change, and it is necessary to re-report the new capability information to the second device. Therefore, the corresponding methods are also different. This embodiment of the application will describe several different situations separately.

[0155] I. The first device reports its capability information.

[0156] In this embodiment, the first device is described as a terminal device and the second device as a network device. Please refer to [link to documentation]. Figure 2 , Figure 2 This is a flowchart illustrating a capability information reporting method provided in an embodiment of this application.

[0157] In step 201, the terminal device determines the capability information.

[0158] The terminal device determines its capability information, which specifically includes the terminal device's ability to support the maximum aggregated spectrum within at least one first range. That is, the maximum aggregated spectrum represents the total spectrum that the terminal device can support within the first range. The total spectrum is less than a first bandwidth, which represents the sum of the maximum bandwidths of each aggregated carrier within the frequency band or frequency band combination supported by the terminal device within the first range.

[0159] It should be noted that in all embodiments of this application, the concept of a carrier can be equivalent to a component carrier. The following description uses the term carrier, but this application is not limited to this and will not be elaborated further here.

[0160] The terminal device can calculate the maximum aggregated spectrum using the following formula:

[0161] Maximum aggregate spectrum (Iterate through all supported frequency bands or combinations of frequency bands)

[0162] Where J represents the total number of aggregated carriers within the first range of frequency bands or frequency band combinations supported by the terminal device, and BW (j) Let j be the maximum bandwidth of carrier j in the terminal device, where carrier j is a carrier within a frequency band or combination of frequency bands supported by the terminal device within a first range. The sum of the maximum bandwidths of each component carrier of the aggregation of all carriers within the first range supported by the terminal device. (Traversing all supported frequency bands or frequency band combinations) means traversing all frequency bands or frequency band combinations supported by the terminal device within a first range, and summing the maximum bandwidth of each component carrier of the supported carrier aggregation.

[0163] For example, as shown in Table 1, if the terminal device supports carrier aggregation of frequency bands A, B, C, and frequency band combinations {Band A + Band B} and {Band A + Band B + Band C}, J represents the number of component carriers supported by the terminal device in the corresponding frequency band. If one carrier is supported in band A, two carriers in band B, and one carrier in band C, and the maximum bandwidth of each component carrier is 100MHz, then the sum of the maximum bandwidths of each component carrier in the carrier aggregation supported by the terminal device in the frequency band combination {Band A + Band B + Band C} is 400MHz. Traversing all the frequency bands and frequency band combinations supported by the terminal device, this value is found to be 400MHz. In embodiments of the present invention, the maximum aggregated spectrum is determined to be less than 400MHz.

[0164] Table 1. Diagram illustrating the maximum bandwidth supported by frequency bands and frequency band combinations for terminal devices.

[0165]

[0166] In this embodiment of the application, the maximum aggregated spectrum can also be represented by the size of the PRB, for example, the maximum aggregated spectrum can be calculated by the following formula:

[0167] Maximum aggregate spectrum (Iterate through all supported frequency bands or combinations of frequency bands)

[0168] Where J represents the total number of carriers supported by the terminal device within the first range of frequency bands or combinations of frequency bands, and μ represents the subcarrier spacing. This represents the maximum number of redundancies (RBs) corresponding to the channel bandwidth BW of carrier j for parameter μ, in one feasible manner. The values ​​of NRB are shown in Tables 2a and 2b, where μ represents different subcarrier spacings (SCS).

[0169] Table 2a shows the maximum number of resource blocks corresponding to different subcarrier intervals.

[0170]

[0171] Table 2b shows the maximum number of resource blocks corresponding to different subcarrier intervals.

[0172]

[0173] In one possible implementation, the terminal device's capability information also includes information about the terminal device's spectrum processing resources. These spectrum processing resources represent the local resources used by the terminal device when receiving and / or transmitting data. These local resources may include, for example, processor resources and / or memory resources, without specific limitations here. Specifically, these spectrum processing resources may include at least one of the following: processing resources used to receive a signal carried on a carrier (referred to as device downlink spectrum processing resources or receive spectrum processing resources), or processing resources used to transmit a signal carried on a carrier (device uplink spectrum processing resources or transmit spectrum processing resources). In device-to-device communication (such as D2D or V2V scenarios), the spectrum processing resources may also be referred to as sidelink processing resources.

[0174] The device receives spectrum processing resources, including at least one of receiving storage resources or receiving processing resources. The receiving storage resources may include at least one of the following: baseband sampling data storage resources, demodulated data soft bit storage resources, decoded transport block storage resources, etc. It is understood that the receiving storage resources may also include more resources, such as high-layer data packet storage resources, but this is not limited here.

[0175] The receiving processing resources may include at least one of the following: radio frequency processing resources, front-end processing resources, channel estimation processing resources, demodulation processing resources, decoding processing resources, decryption processing resources, measurement processing resources, etc. For channel estimation processing resources, they may include at least one of the following: channel estimation resources for PDCCH, channel estimation resources for PDSCH, channel estimation resources for PSCCH, and channel estimation resources for PSDCH. For demodulation processing resources, they may include at least one of the following: demodulation resources for PDCCH, demodulation resources for PDSCH, demodulation resources for PSCCH, and demodulation resources for PSDCH. Decoding processing resources may include polar code decoding units and / or LDPC decoding units. It is understood that the receiving processing resources may also include more resources, such as channel state calculation processing resources, protocol stack processing resources, etc., but this is not specifically limited here.

[0176] The device's transmit spectrum processing resources include transmit storage resources and / or processing resources. Transmit storage resources may include at least one of the following: storage resources for higher-layer data packets, storage resources for MAC layer data packets, and storage resources for transport blocks. It is understood that transmit storage resources may also include more resources, such as encoded data storage resources, modulated data storage resources, mapped data storage resources, etc., but this is not specifically limited here.

[0177] The spectrum processing resources for device transmission may include at least one of the following: radio frequency processing resources, power amplifier processing resources, front-end processing resources, encryption processing resources, data packet assembly processing resources, coding processing resources, modulation processing resources, and transmit power control processing resources. It is understood that the spectrum processing resources for device transmission may also include other resources, such as resources required for processing various channels, such as PUSCH channel processing resources, PUCCH channel processing resources, PSCCH processing resources, and PSDCH processing resources. In practical applications, the spectrum processing resources for device transmission may include even more processing resources; specific details are not limited here.

[0178] In one possible implementation, the capability information of the terminal device further includes first indication information, which indicates a first range of the terminal device. The terminal device may support at least one first range. The first range is a frequency range that the terminal device can support, determined according to one or more frequency bands. For example, if the radio frequency devices of the terminal device support frequency band A, then the first range is frequency band A. It is understood that the first range can also be determined based on the frequency bands supported by other devices of the terminal device, such as the antenna and / or baseband processor, etc., but this is not specifically limited here.

[0179] Optionally, the division of the first range can be the same as the frequency range (FR) in the existing protocol, such as the division of FR1 and FR2 in the 3GPP NR protocol, as shown in Table 3. In this case, the first range is the frequency range represented by FR1, or the first range is the frequency range represented by FR2, or the total frequency range represented by FR1 and FR2 is combined.

[0180] Table 3. Frequency ranges corresponding to FR1 and FR2 as defined in the 3GPP NR protocol.

[0181] FR1 410MHz–7125MHz FR2 24250MHz–52600MHz

[0182] The terminal device may support at least one first range. Specifically, in one possible implementation, as shown in Table 4, the terminal device supports FR1, or the terminal device supports FR2, or the terminal device supports both FR1 and FR2. The terminal device's capability to support the maximum aggregated spectrum within the first range is, for example, the maximum aggregated spectrum supported by the terminal device within FR1, or the maximum aggregated spectrum supported by the terminal device within FR2, or the maximum aggregated spectrum supported by the terminal device within the range jointly defined by FR1 and FR2, i.e., across all frequency bands.

[0183] Table 4. Schematic diagram of the correspondence between the first range and the maximum aggregation spectrum.

[0184]

[0185]

[0186] Optionally, in one possible implementation, the first range may also include a set of one or more frequency bands. For example, first range 1 is set A, first range 2 is set B, set A = {n34, n36, n40, n41}, set B = {n77, n78, n79}, where n34, n36, n40, n41, n77, n78, n79 represent different frequency bands. It should be noted that the frequency bands in the sets included by multiple first ranges can overlap. For example, set A = {n34, n36, n40, n41}, set B = {n41, n77, n78, n79}, that is, the frequency band n41 is in both first range 1 and first range 2. Among them, n34, n36, n41, n77, n78 and n79 are frequency band numbers defined according to 3GPP NR 38.101, see TS 38.101-1 for details.

[0187] In one possible implementation, the first scope can also be defined based on the air interface access protocol supported by the terminal device, such as radio access technology (RAT). For example, for a terminal device supporting both LTE and NR connectivity, if the terminal device supports sharing its spectrum processing resources between all LTE frequency bands and / or frequency band combinations and a portion of NR frequency bands and / or frequency band combinations, then these LTE frequency bands and / or frequency band combinations that can share spectrum processing resources, along with the portion of NR frequency bands and / or frequency band combinations, are defined as the first scope. It is understood that the first scope could also be defined as a portion of LTE frequency bands and / or frequency band combinations and all NR frequency bands and / or frequency band combinations, as long as the frequency bands and / or frequency band combinations of each air interface access protocol can share the terminal device's spectrum processing resources; no specific limitation is made here. For a terminal device supporting both LTE and NR connectivity, the first scope could also be the sharing of device spectrum processing resources between carriers of all frequency bands or frequency band combinations within LTE, and the sharing of processing capabilities between carriers of all frequency bands or frequency band combinations within NR, but carriers between LTE and NR cannot share processing capabilities. Several examples of defining the first range based on the air interface protocols supported by the terminal device are shown in Table 5 below.

[0188] Table 5. Schematic diagram of the correspondence between the first range and the maximum aggregate spectrum.

[0189]

[0190]

[0191] In one possible implementation, the first range can also be defined based on the connections supported by the terminal device. For example, a terminal device supporting MR-DC supports two NR connections. If the frequency bands and / or combinations of frequency bands supported by the terminal device in the two NR connections can share spectrum processing resources, then the frequency bands and / or combinations of frequency bands of the two NR connections of the MR-DC-supporting terminal device are defined as the first range. It is understood that if the frequency bands and combinations of frequency bands between multiple connections of the terminal device can share spectrum processing resources, then these connections that can share spectrum processing resources are defined as the first frequency resources. Of course, if two NR connections cannot share processing resources, but can share spectrum processing resources within the connection, then the frequency bands and / or combinations of frequency bands supported within the connection that shares processing resources can be defined as a first range.

[0192] In one possible implementation, the first range can also be defined based on the link types supported by the terminal device. For example, if a terminal device supporting cellular air interface links (Uu-link) and sidelinks can share spectrum processing resources with the Uu-link frequency bands and / or frequency band combinations of the sidelink, then Uu-link and sidelink are defined as the first range. Alternatively, the frequency bands and / or frequency band combinations of Uu-link and sidelink that can share spectrum processing resources are defined as the first range. Carriers within the frequency bands and / or frequency band combinations supported by Uu-link and sidelink can share spectrum processing resources. Examples are shown in Table 6 below.

[0193] Table 6. Schematic diagram of the correspondence between the first range and the maximum aggregation spectrum.

[0194]

[0195] In one possible implementation, the first scope can also be defined based on the service type supported by the terminal device, or the supported application scenario or supported feature. For example, for a terminal device that supports eMBB service and V2X feature, if some or all of the frequency bands and / or frequency band combinations supported by the terminal device in the eMBB scenario and the frequency bands and / or frequency band combinations supported in the V2X scenario can share spectrum processing resources, then these frequency bands and / or frequency band combinations that can share spectrum processing resources are defined as the first scope.

[0196] In one possible implementation, multiple frequency ranges can be defined using Table 7 below. The frequency range division example here is based on whether most terminal devices in the industry can share radio frequency (RF) components. For example, for receiving wireless signals with a spectrum less than 1 GHz, the same receiving RF channel can be shared. Therefore, wireless signals less than 1 GHz are divided into one frequency range, and so on.

[0197] Table 7. Schematic diagram of frequency range and corresponding spectrum range

[0198] Frequency Range 1 <1GHz Frequency Range 2 1GHz-3GHz Frequency Range 3 3GHz-5GHz Frequency Range 4 5GHz-8GHz Frequency Range 5 10GHz-30GHz Frequency Range 6 30GHz-45GHz Frequency Range 7 45GHz-75GHz Frequency Range 8 70GHz-80GHz

[0199] The first range can be defined as one or more frequency ranges. Carriers within the first range can share spectrum processing resources. For example, when the first range includes FR1, FR2, FR3, and FR4 as indicated in Table 7, the terminal device supports inter-carrier spectrum processing resource sharing among FR1, FR2, FR3, and FR4. The spectrum ranges indicated by FR1, FR2, FR3, and FR4 are less than 8 GHz. When the first range is defined as FR1, FR2, FR3, and FR4, it means that spectrum processing resources are shared among aggregated carriers less than 8 GHz.

[0200] It is understood that the first range is determined by the operating mode of at least two carriers that can share spectrum processing resources. This operating mode is determined by at least one of the following: the frequency band in which the carriers reside, the frequency band combination, the supported air interface protocols, the supported connection types, the supported link types, and the supported service types. For example, the first range can be defined by both the air interface protocols and service types supported by the terminal device, or by the link types and different connections supported by the terminal device, or by the frequency band range supported by the operator; the specific definition is not limited here.

[0201] It should be noted that the above-mentioned sharing of spectrum processing resources among at least two carriers in the first range refers to the sum of the maximum spectrum processing resources required by the terminal device when it uses at least two carriers in the first range to transmit data, and when the terminal device can independently use each carrier less than the at least two carriers for data transmission.

[0202] In one possible implementation, the capability information of the terminal device further includes second indication information, which indicates the minimum guaranteed bandwidth of at least one carrier within the first range, the minimum guaranteed bandwidth representing the processing capacity reserved by the terminal device for that carrier.

[0203] The spectrum processing resources that the terminal device can share within the first range are less than or equal to the sum of the total aggregated spectrum and the minimum guaranteed bandwidth of the at least one carrier, which can be expressed, for example, by the following formula:

[0204]

[0205] Where K is the number of carriers effective within the first range, and the channel bandwidth is... (k) The spectrum allocated to the effective carrier k within the first range, where L is the number of carriers within the first range that define the minimum guaranteed bandwidth, and the minimum guaranteed bandwidth... (l) This is the minimum guaranteed bandwidth for carrier l within the first range. This represents the sum of the minimum guaranteed bandwidths of all carriers with minimum guaranteed bandwidths within the first range. This represents the sum of the schedulable spectrum of all active carriers within the first range. Here, active carriers refer to carriers that can be used for data transmission.

[0206] The minimum guaranteed bandwidth can be determined according to predefined rules or autonomously by the terminal device, based on the channels it needs to monitor and / or the communications it needs to maintain and / or its implementation architecture. For example, the minimum guaranteed bandwidth for a carrier can be defined as the minimum bandwidth required for the terminal device to maintain one or more communication functions on that carrier. These communication functions may include at least one of the following: initial access, receiving system messages, receiving paging messages, random access, uplink signaling feedback, small packet reception or transmission, wake-up signal reception or transmission, downlink control channel monitoring, measurement, mobility, channel quality detection, timing synchronization, frequency tracking, phase tracking, beam tracking, and selection. It is understood that other communication functions, such as cell selection and reselection, may also be included, but this is not specifically limited here.

[0207] In one possible implementation, within a 3GPP NR system, the minimum guaranteed bandwidth can be the bandwidth that the terminal must support to guarantee successful initial access. For example, the bandwidth defined by the control resource set (CORESET) numbered zero. Within FR1 defined by NR, the minimum guaranteed bandwidth can take any of the following values: 5MHz, 10MHz, 20MHz, or 40MHz. Alternatively, at least one bandwidth of the initial BWP that the NR system specifies must support can be defined as the minimum guaranteed bandwidth.

[0208] In 3GPP LTE systems, the minimum guaranteed bandwidth can be the bandwidth of the synchronization channel, which is 1.4MHz. The control resource set is the frequency domain resource size of the downlink control channel (PDCCH). The minimum guaranteed bandwidth can also be defined in units of resource blocks actually used for data transmission. For example, in 3GPP NR systems, when the subcarrier spacing is 30kHz, the minimum guaranteed bandwidth is 48 resource blocks (RBs). In 3GPP LTE systems, when the subcarrier spacing is 15kHz, the minimum guaranteed bandwidth is 6 RBs. Depending on the frequency band of the carrier supported by the terminal device, the air interface protocol used, the connection attributes, the link attributes, and the supported service types, the minimum guaranteed bandwidth of the carrier supported by the terminal device can have different values. For example, the minimum guaranteed bandwidth of a carrier in frequency band A is 20MHz, and the minimum guaranteed bandwidth of a carrier in frequency band B is 40MHz. Furthermore, the minimum guaranteed bandwidth of an LTE carrier is 1.4MHz, the minimum guaranteed bandwidth of a carrier in the FR1 band of NR is 20MHz, and the minimum guaranteed bandwidth of a carrier in the FR2 band of NR is 50MHz. Alternatively, the minimum guaranteed bandwidth for a Uu link carrier is 40MHz, and the minimum guaranteed bandwidth for a sidelink carrier is 20MHz. Or, the minimum guaranteed bandwidth for an eMBB carrier is 40MHz, the minimum guaranteed bandwidth for an NR V2X carrier is 40MHz, the minimum guaranteed bandwidth for an LTE V2X carrier is 20MHz, the minimum guaranteed bandwidth for an mIoT carrier is 5MHz, the minimum guaranteed bandwidth for a URLLC carrier is 20MHz, and so on.

[0209] It should be noted that the minimum guaranteed bandwidth of a carrier can be zero. When the minimum guaranteed bandwidth of a carrier is 0, it means that the terminal device will not reserve spectrum processing resources for that carrier.

[0210] Figure 5 This is a schematic diagram illustrating the maximum aggregated spectrum supported by a terminal device according to an embodiment of this application. Figure 5 In this scenario, the terminal device operates in LTE and NR dual-connectivity mode, and is configured or activated with one LTE carrier 1 and one NR carrier 2. Carrier 1 has a minimum guaranteed bandwidth of 10MHz, carrier 2 has a bandwidth of 40MHz, and the maximum aggregated spectrum is 100MHz. Therefore, the spectrum processing resources that the terminal device can share are: 100MHz - 10MHz - 40MHz = 50MHz. Carrier 2 can be scheduled up to a maximum of 90MHz, and carrier 1 can be scheduled up to 10MHz. For example, carrier 1 can be scheduled up to the maximum LTE bandwidth of 20MHz.

[0211] It should be noted that the terminal device will only reserve the corresponding minimum guaranteed bandwidth when the carrier is active.

[0212] For example, the terminal device supports carrier aggregation in frequency band A and frequency band B. The maximum aggregated spectrum of the terminal device is 100MHz. The minimum guaranteed bandwidth of carrier A in frequency band A is 10MHz, and the minimum guaranteed bandwidth of carrier B in frequency band B is 20MHz.

[0213] When carrier A is not active and carrier B is active, the total spectrum processing resources that the terminal device can use for carrier B are 100MHz.

[0214] When carrier B is not active and carrier A is active, the terminal device can use 100MHz of shared spectrum processing resources for carrier A.

[0215] When both carrier A and carrier B are active, the maximum spectrum processing resource that the terminal device can use to process carrier A and carrier B simultaneously is 100MHz. Among them, the spectrum processing resource that the terminal device can share is 70MHz (100MHz-10MHz-20MHz), the maximum spectrum processing resource that the terminal device can use to process carrier A is 80MHz (100MHz-20MHz), and the maximum spectrum processing resource that the terminal device can use to process carrier B is 90MHz (100MHz-10MHz).

[0216] In one possible implementation, the capability information of the terminal device also includes whether the terminal device supports adjusting the minimum guaranteed bandwidth corresponding to the carrier.

[0217] For example, a terminal device adjusts the minimum bandwidth corresponding to a carrier based on a specific scenario. For instance, the terminal device supports carrier aggregation of carrier A and carrier B. The maximum channel bandwidth of carrier A is 100MHz, the maximum channel bandwidth of carrier B is 100MHz, and the maximum aggregated spectrum of the terminal device is 100MHz. The terminal device can determine that the minimum guaranteed bandwidth of the primary carrier is 40MHz, and the minimum guaranteed bandwidth of the secondary carrier is 0MHz. The primary carrier can have a maximum of 100MHz of spectrum available for data transmission, while the secondary carrier can have a maximum of 60MHz (100MHz - 40MHz) of spectrum available for data transmission. Therefore, when carrier A is the primary carrier of the terminal device, and its minimum guaranteed bandwidth is 40MHz, carrier A can have 100MHz available for data transmission, while carrier B can have a maximum of 60MHz available for data transmission. If carrier A is changed from the primary carrier to the secondary carrier, and its guaranteed bandwidth is now 0, then carrier A can have a maximum of 60MHz available for data transmission.

[0218] If the terminal device supports adjusting the minimum guaranteed bandwidth corresponding to the carrier, it can improve the efficiency of resource utilization when the application scenario changes.

[0219] It should be noted that when the minimum guaranteed bandwidth is determined autonomously by the terminal device, the terminal device needs to send the minimum guaranteed bandwidth to the network device. When the minimum guaranteed bandwidth is determined according to predefined rules, the terminal device does not need to report the minimum guaranteed bandwidth.

[0220] To reduce the scheduling complexity and signaling load of terminal and network devices, terminal devices can set a first granularity of capability. The unit of this first granularity can be MHz, Hz, or GHz, for example, 5MHz or 10MHz. Alternatively, the unit can be other units, such as RB or RBG. The first granularity can be determined according to predefined rules, such as specifying a first granularity of 5MHz. The first granularity can also be determined by the terminal device based on its capabilities. It is understood that a larger first granularity reduces the scheduling complexity of network devices and lowers the signaling load. A smaller first granularity provides greater flexibility for the terminal device.

[0221] In one possible implementation, the maximum aggregated spectrum capability of the terminal device is represented by the number of second granularities. The second granularity is an integer multiple of the first granularity or the same as the first granularity. For example, if the terminal device determines that the size of the first granularity is 10MHz and the second granularity is 20MHz, and the information of the maximum aggregated spectrum capability is defined by two second granularities, that is, integer multiples of 20MHz, then when determining the maximum aggregated spectrum, the value of the maximum aggregated spectrum can be expressed as an integer multiple of 20MHz, for example, the maximum aggregated spectrum is 80MHz or 100MHz.

[0222] Understandably, the terminal device can also determine a third granularity of the shared spectrum processing resources. The third granularity is an integer multiple of the first granularity or the same as the first granularity. For example, if the third granularity is equal to the first granularity, and the first granularity is 20MHz, then the third granularity of the spectrum processing resources that the terminal device can share within the first range is 20MHz. The maximum aggregated spectrum supported by the terminal device within the first range is 100MHz, and the terminal device supports carrier aggregation of two carriers. Then, the combination of spectrum processing resources that the terminal device can support {carrier 1, carrier 2} = {(0, 20), (0, 40), (0, 60), (0, 80), (0, 100), (20, 0), (20, 20), (20, 40)(20, 60)(20, 80)(40, 0)(40, 20), (40, 40), (40, 60), (60, 0)(60, 20), (60, 40), (80, 0)(80, 20), (100, 0)}, where the unit of the combination of spectrum processing resources is MHz.

[0223] In one possible implementation, the terminal device's capability information further includes third indication information. This third indication information indicates that the terminal device supports scheduling multiple non-contiguous resource units (RUs) within a carrier within a first range; that is, the terminal device supports scheduling multiple non-contiguous resource units within a single carrier. The sum of the total number of schedulable non-contiguous resource units within the aggregated carrier within the first range is less than or equal to the maximum aggregated spectrum. The size of the resource unit can be determined according to predefined rules. For example, the size of the resource unit may be 5 MHz. Alternatively, the size of the resource unit may be the size of a frequency domain block using the same precoding, such as one or more resource block groups (RBGs). It can also be determined based on the terminal device's capabilities. Preferably, the size of the resource unit is equal to the first granularity or an integer multiple of the first granularity.

[0224] In one possible implementation, the third indication information is used to instruct the terminal device to support scheduling multiple non-contiguous resource units within a first range of carriers, wherein the sum of the multiple non-contiguous resource units that can be scheduled within the first range of carriers is less than or equal to the maximum aggregated spectrum.

[0225] In one possible implementation, at least one carrier among all carriers supported by the terminal device within the first range includes non-contiguous resource elements. For example, each carrier among all carriers supported by the terminal device within the first range includes non-contiguous resource elements. Alternatively, two of the five carriers supported by the terminal device within the first range each include non-contiguous resource elements.

[0226] In one possible implementation, the third instruction information further includes at least one of the following: a first granularity value, a second granularity value, a third granularity value, and the size of the resource unit.

[0227] To reduce the scheduling complexity of terminal and network devices, terminal devices are designed to support continuous spectrum processing within a carrier. For example... Figure 6 As shown, the maximum aggregated spectrum supported by the terminal device within the first range is 100MHz. The terminal device activates carrier 1 in frequency band A, corresponding to a continuous 40MHz spectrum, and carrier 2 in frequency band B, corresponding to a continuous 60MHz spectrum. The sum of the bandwidths of carrier 1 and carrier 2 equals the maximum aggregated spectrum. To improve system performance and fully utilize diversity gain, the terminal device determines that it supports the processing of multiple non-contiguous resource units within the carriers within the first range. The value of this non-contiguous resource unit can be the smallest granularity of the maximum aggregated spectrum capability, or other values. Figure 7As shown, the terminal device supports carrier aggregation in frequency band A and frequency band B within the first range. The maximum aggregated spectrum supported within the first range is 100MHz, and the resource unit size is 10MHz. The terminal device can schedule two non-contiguous resource units in the frequency domain when it activates carrier 1 in frequency band A, and the total spectrum of the four resource units is 40MHz. The terminal device can schedule six non-contiguous resource units in the frequency domain when it activates carrier 2 in frequency band B, and the total spectrum of the six resource units is 60MHz.

[0228] It should be noted that, in the embodiments provided in this application, the carriers supported by the terminal device may include carriers of continuous spectrum or carriers of non-continuous spectrum, and no limitation is made here.

[0229] It should be noted that the resource unit size of each carrier in a terminal device can be the same or different. When the resource unit size of each carrier is the same, the design and implementation of the terminal device is simple and easy. When the resource unit size of each carrier is different, the network device can determine different resource unit sizes for different types of terminal devices, which can increase the flexibility of network device resource scheduling.

[0230] It should be noted that the carrier aggregation described in the embodiments provided in this application is carrier aggregation in a broad sense. Any carrier aggregation in which two or more carriers are used for data transmission at the same time is called carrier aggregation, regardless of whether these carriers are in the same frequency band (e.g., one is frequency band A and the other is frequency band B), whether they are using the same air interface protocol (e.g., they can be LTE air interface or NR air interface respectively), whether they are using the same connection (e.g., they can be two different NR connections respectively), or whether they are using the same link (e.g., they are Uu link and side link respectively).

[0231] In one possible implementation, the capability information of the terminal device further includes fifth indication information, which is used to indicate the maximum number of aggregation layers of the terminal device within a first range.

[0232] The maximum number of aggregation layers supported by a terminal device within the first range can be expressed by the following formula:

[0233]

[0234] Among them, v (j) The maximum number of MIMO layers for carrier j is indicated by J, where J represents the total number of aggregated carriers in the first range, either in frequency bands or combinations thereof.

[0235] It should be noted that the capability information in the embodiments of this application may include the specific value of the maximum aggregated spectrum, or it may include a scaling factor, which is used to determine the maximum aggregated spectrum.

[0236] For example, when the capability information includes a scaling factor, the network device calculates the maximum aggregated spectrum of the terminal device according to the following formula after receiving the capability information reported by the terminal device:

[0237]

[0238] Among them, BW (j) This represents the maximum bandwidth of carrier j. Alternatively, the maximum aggregated spectrum of the terminal device can also be represented by the following formula:

[0239]

[0240] in, This represents the largest resource block corresponding to carrier j.

[0241] It is understandable that the maximum aggregated spectrum of the terminal device can also be calculated using other formulas, but specific formulas are not limited here.

[0242] The terminal device determines its capability information, which specifically includes the capability information of the maximum aggregated spectrum supported by the terminal device within at least one first frequency range. The terminal device may determine more than one first frequency range, and the maximum aggregated spectrum capability information supported within each first frequency range may be the same or different. As shown in Table 8 below, this indicates that the terminal device has the capability to support three first frequency ranges, with a defined maximum aggregated spectrum within each first frequency range.

[0243] Table 8. Schematic diagram of the correspondence between the first range and the maximum aggregate spectrum.

[0244]

[0245] In step 202, the terminal device sends capability information to the network device.

[0246] After determining the capability information, the terminal device sends the capability information to the network device.

[0247] In one possible implementation, the terminal device sends capability information to the network device via higher-layer signaling through a terminal device capability information reporting mechanism. During the initial access process of the terminal device, the terminal device sends capability information to the network device through capability information reporting, for example, by sending the capability information to the network device via RRC configuration signaling.

[0248] Furthermore, when a terminal device sends capability information to a network device, the capability information can be represented in various different ways. For example, the maximum aggregated spectrum within a first range included in the capability information can be reported in the following format:

[0249] CA-AggregatedSpectrum::=ENUMERATED{40MHz,50MHz,150MHz,200MHz,250MHz,300MHz,...}

[0250] Optionally, the reporting format for the maximum aggregated spectrum can also be represented by resource blocks. In this case, the number of resource blocks may differ for different subcarrier intervals. For example, for a subcarrier interval of 30 kHz, the maximum aggregated spectrum within the first range included in the capability information can be reported according to the following format:

[0251] CA-AggregatedSpectrum::=ENUMERATED{25RB,50RB,65RB,135RB,273RB,…}

[0252] For a subcarrier spacing of 15 kHz, the maximum aggregated spectrum within the first range included in the capability information can be reported in the following format:

[0253] CA-AggregatedSpectrum::=ENUMERATED{12RB,25RB,50RB,135RB,…}

[0254] In one possible implementation, the terminal device can also represent the capability information of the maximum aggregated spectrum in the capability information by reporting a scaling factor, for example:

[0255] CA-AggregatedSpectrumFactor::=ENUMERATED{0.4,0.5,0.6,0.7,0.8,0.9,...}

[0256] The maximum aggregation spectrum can take different values ​​within different first ranges. These can be represented by different information elements.

[0257] It is understandable that there are many ways for terminal devices to report capability information to network devices, and no specific method will be specified here.

[0258] The terminal device sends capability information to the network device, and further includes the network device receiving the capability information sent by the terminal device to the network device.

[0259] Furthermore, in one possible implementation, the embodiment further includes step 203, in which the network device determines a first frequency domain resource within a first range based on capability information.

[0260] After receiving the capability information reported by the terminal device, the network device determines the first frequency domain resource within the first range to be scheduled based on the capability information.

[0261] Specifically, when determining the first frequency domain resources that need to be scheduled, the network device ensures that the first frequency domain resources scheduled within the first range do not exceed the maximum aggregated spectrum of carrier aggregation supported by the terminal device within the first range as indicated by the capability information.

[0262] In one possible implementation, the network device configures the channel bandwidth of each carrier in the carrier aggregation within a first range, and the network device determines that the sum of the channel bandwidths of all configured carriers within the first range does not exceed the maximum aggregated spectrum indicated by the capability information.

[0263] In one possible implementation, the network device activates the bandwidth of the active BWP for each carrier within a first range, and determines that the sum of the channel bandwidths of all active BWPs within the first range does not exceed the maximum aggregated spectrum indicated by the capability information.

[0264] In one possible implementation, the network device configures the channel bandwidth of the BWPs of the configured carriers within a first range. The network device determines that the sum of the maximum BWP values ​​of all configured carriers does not exceed the maximum aggregated spectrum indicated by the capability information. For example, if the network device configures N carriers, where N is a positive integer greater than or equal to 1, and each carrier is configured with one or more BWPs, then... The maximum aggregated spectrum not exceeding the capacity information indication.

[0265] In one possible implementation, network device capability information and the effective carriers determine a first frequency range. For example, the network device learns from the capability information reported by the terminal device that the maximum aggregated spectrum supported by the terminal device within the first range is 100MHz. Under operator 1's network, operator 1 allocates 40MHz of spectrum in frequency band A and 60MHz of spectrum in frequency band B within the first range. Under operator 1's network, the network device configures two carriers for the terminal device. Carrier 1 is in frequency band A, and its maximum BWP is 40MHz; carrier 2 is in frequency band B, and its maximum BWP is 60MHz. If, under operator 2's network, operator 2 allocates 80MHz of spectrum in frequency band A and 40MHz of spectrum in frequency band B within the first range, the network device configures two carriers for the terminal device under operator 2's network. Carrier 1 is in frequency band A, and its maximum BWP is 60MHz; carrier 2 is in frequency band B, and its maximum BWP is 40MHz. That is, regardless of whether it is under the network of operator 1 or operator 2, the sum of the maximum BWP of the carriers configured by the network equipment for the terminal equipment shall not exceed the maximum aggregated spectrum indicated in the capability information reported by the terminal equipment.

[0266] In one possible implementation, the network device further determines the size of the first range to be scheduled based on the first indication information in the capability information, thereby determining the carriers to be configured.

[0267] For example, the network device determines a first range as Uu link and sidelink based on the first indication information, and the maximum supported aggregated spectrum within the first range is 100MHz. If the network device does not configure a sidelink for the terminal device, then the network device configures carrier 1 for the terminal device, and the bandwidth of carrier 1 is less than or equal to 100MHz. If the network device configures both Uu link and sidelink for the terminal device, then the bandwidth of carrier 1 in Uu link is less than or equal to 60MHz, and the bandwidth of carrier 2 in sidelink is less than or equal to 40MHz. The total configured bandwidth of carrier 1 in Uu link and carrier 2 in sidelink does not exceed 100MHz.

[0268] In one possible implementation, the network device further determines a first frequency domain resource within a first range based on second indication information in the capability information.

[0269] Specifically, the network device determines the minimum guaranteed bandwidth for each carrier within the first range based on the second indication information in the capability information. When configuring the first frequency domain resources for the terminal device, the network device determines that the frequency domain resources that can be shared by the carriers do not exceed the sum of the maximum aggregated spectrum and the minimum guaranteed bandwidth of the effective carrier.

[0270] Figure 8 This is a schematic diagram illustrating the maximum aggregated spectrum supported by another terminal device provided in an embodiment of this application. Figure 8 In this scenario, based on the capability information reported by the terminal devices, the network device determines that frequency band A and frequency band B can share frequency domain resources. When only the carrier of frequency band A is active, the network device can allocate a bandwidth to the active carrier of frequency band A that is less than or equal to the maximum aggregated spectrum. When both carriers of frequency band A and frequency band B are active simultaneously, the network device can allocate a bandwidth to the carrier of frequency band A that is less than or equal to the maximum aggregated spectrum minus the minimum guaranteed bandwidth of the carrier of frequency band B, and the network device can allocate a bandwidth to the carrier of frequency band B that is less than or equal to the maximum aggregated spectrum minus the minimum guaranteed bandwidth of the carrier of frequency band A.

[0271] Figure 9 This is a schematic diagram illustrating the maximum aggregated spectrum supported by another terminal device provided in an embodiment of this application. Figure 9In this process, based on the capability information reported by the terminal devices, the network device learns that Uulink and Sidelink can share frequency domain resources. During the time period t1 to t2, if only the Uulink carrier is active, the network device can configure a bandwidth for the active Uulink carrier that is less than or equal to the maximum aggregated spectrum. During the time period t2 to t3, if both the Uulink and Sidelink carriers are active, the network device can configure a bandwidth for the Uulink carrier that is less than or equal to the maximum aggregated spectrum minus the minimum guaranteed bandwidth of the Sidelink carrier. Similarly, during the time period t2 to t3, if only the Sidelink carrier is active, the network device can configure a bandwidth for the active Sidelink carrier that is less than or equal to the maximum aggregated spectrum. For example, Figure 9 As shown, Uulink has a minimum guaranteed bandwidth of 40MHz, Sidelink has a minimum guaranteed bandwidth of 20MHz, and the maximum aggregated spectrum is 100MHz. Figure 9 The t1, t2, and t3 shown represent three different time points. Sidelink and Uulink can belong to the same frequency band or different frequency bands; this is not specified here.

[0272] Figure 9 The implementation shown illustrates a specific application scenario where, during the initial network access phase of the terminal device, the total bandwidth of the carriers aggregated for Uu-link data transmission is less than or equal to the maximum aggregated spectrum, for example, a maximum aggregated spectrum of 100MHz. After network access, the terminal device activates sidelink, with a minimum guaranteed bandwidth of 40MHz. Therefore, the total bandwidth of the carriers aggregated for Uu-link data transmission is less than or equal to 60MHz.

[0273] In one possible implementation, the network device further determines a first frequency domain resource within a first range based on third indication information in the capability information.

[0274] Specifically, the network device determines, based on the third instruction information, that multiple non-contiguous resource units can be configured for the carrier of the terminal device within the first range.

[0275] In one possible implementation, the network device further determines a first frequency domain resource within a first range based on the fifth indication information in the capability information.

[0276] Specifically, the network device determines the total number of MIMO layers supported by the terminal device within the first range based on the fifth instruction information, and configures the total number of MIMO layers for each carrier, so that the sum of the total number of MIMO layers on all configured carriers does not exceed the maximum aggregation layer.

[0277] Understandably, in practical applications, network devices can configure first frequency domain resources based on more information in the capability information, but this is not limited here.

[0278] After determining the first frequency domain resources, the network device generates the first scheduling information based on the first frequency domain resources.

[0279] Furthermore, in one possible implementation, this embodiment also includes step 204, in which the network device sends first scheduling information to the terminal device.

[0280] After generating the first scheduling information, the network device sends the first scheduling information to the terminal device.

[0281] In one possible implementation, the network device can carry the first scheduling information through one or more of RRC signaling, MAC layer signaling, or physical layer signaling. The first scheduling information can be sent to the terminal device in one signaling message or in multiple signaling messages, which is not limited here.

[0282] For example, the network device configures the maximum BWP of carrier 1 to be 60MHz and the maximum BWP of carrier 2 to be 40MHz. The network device carries these two configuration information through RRC signaling and sends them to the terminal device.

[0283] For example, a network device configures carrier 1 to have two BWPs via RRC signaling, with BWP1 having a bandwidth of 80MHz and BWP2 having a bandwidth of 60MHz. The network device also configures carrier 2 to have two BWPs, with BWP3 having a bandwidth of 20MHz and BWP4 having a bandwidth of 40MHz. At time T1, the network device activates BWP1 and BWP3 by carrying activation signaling via physical layer signaling or MAC signaling. At time T2, it activates BWP2 and BWP4 by carrying activation signaling via physical layer signaling or MAC signaling.

[0284] It is understandable that in practical applications, network devices may also send the first scheduling information in other ways, which are not specified here.

[0285] The network device sends the first scheduling information to the terminal device, and further includes the terminal device receiving the first scheduling information.

[0286] Furthermore, in one possible implementation, this embodiment also includes step 205, in which the terminal device determines spectrum processing resources based on the first scheduling information.

[0287] After receiving the first scheduling information, the terminal device determines the first frequency domain resource scheduled by the network device based on the first scheduling information. This first frequency domain resource is used by the first device for data transmission, and the first frequency domain resource is less than or equal to the maximum aggregated spectrum. After determining the first frequency domain resource, the terminal device determines its spectrum processing resources based on the first frequency domain resource. These spectrum processing resources include the terminal device's processing resources used when receiving and / or transmitting data carried on the first frequency domain resource.

[0288] In one possible implementation, the terminal device determines the carriers active within a first range based on the first frequency domain resources, and configures the corresponding spectrum processing resources according to the active carriers. For example, if the network device is instructed to activate two carriers, carrier 1 and carrier 2, in the first frequency domain resources, with bandwidths of 20MHz and 40MHz respectively, then the terminal device allocates 20MHz and 40MHz of spectrum processing resources to carrier 1 and carrier 2 respectively.

[0289] For example, in the first frequency domain resources, the network device configures two carriers for the terminal device. Carrier 1 is in frequency band A with a maximum BWP of 40MHz, and carrier 2 is in frequency band B with a maximum BWP of 60MHz. Then the terminal device allocates 40MHz of spectrum processing resources to carrier 1 and 60MHz of spectrum processing resources to carrier 2.

[0290] In one possible implementation, when the terminal device determines, based on the first frequency domain resources, that the effective carriers within the first range include non-contiguous resource elements, the terminal device configures corresponding spectrum processing resources according to the effective non-contiguous carriers. For example, in the first frequency domain resources, the network device configures two carriers for the terminal device, carrier 1 including contiguous resource elements and carrier 2 including non-contiguous resource elements. The terminal device then allocates a portion of spectrum processing resources to carrier 1 and allocates corresponding spectrum processing resources to the non-contiguous resource elements in carrier 2 respectively.

[0291] In one possible implementation, after determining the first frequency domain resource, if the terminal device learns that the spectrum simultaneously received and / or transmitted within the first range indicated by the first frequency domain resource exceeds the maximum aggregated spectrum supported by the terminal device within the first range, then the terminal device determines that the first scheduling information is incorrect. The terminal device can discard the first scheduling information or send a prompt indicating that the first scheduling information is incorrect to the network device. It is understood that the terminal device can also, based on its maximum supported aggregated spectrum, not receive and / or not transmit the data corresponding to the portion of the spectrum in the first frequency domain resource that exceeds the maximum aggregated spectrum. The specifics are not limited here.

[0292] In this embodiment, the maximum aggregated spectrum supported by the terminal device is less than the sum of the maximum bandwidths of each carrier within the first range of frequency bands or frequency band combinations, which reduces the spectrum processing capability that the terminal device needs to design and helps to reduce the cost of the terminal device.

[0293] II. Update the reporting capability of the first device.

[0294] In this embodiment, the first device is described as a terminal device and the second device as a network device. In this embodiment, after the first device reports capability information, the corresponding capability information changes. There are various reasons why the capability information of the terminal device changes, such as changes under different air interface protocols or changes in the application scenario.

[0295] The updating of capability information includes updating one or more pieces of information in the capability information described in Embodiment 1, such as updating the maximum aggregated spectrum, updating the first range, updating the third indication information, etc. Here, the updating of the first range by the terminal device is used as an example for explanation. The process of updating other information in the capability information reported by the terminal device is similar and will not be described one by one.

[0296] like Figure 3 The diagram shown is a flowchart illustrating another capability information reporting method according to an embodiment of this application.

[0297] In step 301, the terminal device determines the capability information.

[0298] In step 302, the terminal device sends capability information to the network device.

[0299] In step 303, the network device determines the first frequency domain resource within the first range based on the capability information.

[0300] In step 304, the network device sends the first scheduling information to the terminal device.

[0301] In step 305, the terminal device determines the spectrum processing resources based on the first scheduling information.

[0302] Steps 301 to 305 in this embodiment are the same as those described above. Figure 2 Steps 201 to 205 in the embodiment are similar, and will not be described in detail here.

[0303] In step 306, the terminal device sends a fourth instruction message to the network device.

[0304] When capability information changes, the terminal device sends updated capability information to the network device. The terminal device can update all or part of the capability information. For example, when the first range changes, the terminal device will send a fourth indication message to the network device, which indicates the update of the terminal device's capability information.

[0305] The first range is determined by the operating mode of at least two carriers that can share spectrum processing resources. This operating mode is determined by at least one of the following: the frequency band in which the carriers reside, the frequency band combination, the supported air interface protocols, the supported connection types, the supported link types, and the supported service types. For example, the first range can be defined by the air interface protocols and service types supported by the terminal device, or by the link types and different connections supported by the terminal device, or by the frequency band range supported by the operator. The first range changes when the operating mode changes. For example, if the first range is defined based on the air interface access protocols supported by the terminal device, and the terminal device supports both non-standalone (NSA) and standalone (SA) networks, and under an NSA network the terminal device supports both LTE and NR air interface protocols, and under an SA network the terminal device supports NR, then when the terminal device accesses from an NSA network to an SA network, the determination of the first range changes from LTE and NR air interfaces to only NR air interface, thus the terminal device determines that the first range has changed. Alternatively, if the first range is defined based on the set of frequency bands supported by the terminal device, and the terminal device adds new frequency bands and / or combinations of frequency bands that it can support, then the terminal device determines that the first range has changed. Or, if the link type supported by the terminal device changes, for example from supporting only Uu links to supporting both Uu links and Sidelinks, then the terminal device determines that the first range has changed.

[0306] It is understandable that in practical applications, there may be many other situations where the first range changes, but specific details are not limited here.

[0307] For example, if the first range is defined based on the air interface access protocols supported by the terminal device, and the terminal device moves from an NSA (Non-standalone) network to an SA (standalone) network, with the NSA network terminal supporting both LTE and NR air interface protocols and the SA network terminal supporting NR, then the first range changes from supporting both LTE and NR air interface protocols to supporting only NR air interface protocols. Therefore, the terminal device needs to update its capability information, and the network device needs to reschedule resources for the corresponding matching. Alternatively, if the first range is defined based on the set of frequency bands supported by the terminal device, and new frequency bands and / or combinations of frequency bands are added, the first range may change. Therefore, the terminal device needs to update its capability information, and the network device needs to reschedule resources for the corresponding matching. Or, if the link type supported by the terminal device changes, from supporting only Uu link to supporting both Uu link and Sidelink, causing a change in the first range, then the terminal device needs to update its capability information, and the network device needs to reschedule resources for the corresponding matching.

[0308] In one possible implementation, the terminal device can update its capability information to the network device by de-registering and / or detaching from the network. It is understood that other methods can also be used to update the capability information to the network device, such as updating the capability information by registering and / or attaching to the network, or updating the capability information by sending auxiliary information, etc. The specific method is not limited here.

[0309] In step 307, the network device determines the second frequency domain resource based on the fourth instruction information.

[0310] After receiving the fourth instruction information sent by the terminal device, the network device determines the first range that needs to be updated based on the fourth instruction information, and then determines the second frequency domain resource based on the updated first range and the capability information of the terminal device. The second frequency domain resource is used for data transmission between the network device and the terminal device.

[0311] In this embodiment, the method for the network device to determine the second frequency domain resources based on the updated first range and the capability information of the terminal device is as follows: Figure 2 The method by which the network device determines the first frequency resource based on the first range and the capability information of the terminal device in step 203 of the embodiment is similar, and will not be described in detail here.

[0312] In step 308, the network device sends the second scheduling information to the terminal device.

[0313] In step 309, the terminal device determines the second spectrum processing resource based on the second scheduling information.

[0314] Steps 308 and 309 in this embodiment are the same as those described above. Figure 2 Steps 204 and 205 in the embodiment are similar, and will not be described in detail here.

[0315] In this embodiment, the terminal device may explicitly include the updated first range information in the fourth indication information, or it may omit the updated first range information in the fourth indication information and only include the indication update message. After receiving the indication update message sent by the terminal device, the network device will send a query message to the terminal device. This query message is used to query the updated capability information of the terminal device. Alternatively, the terminal device may also send the updated first range information to the network device through UE assisted information; the specific method is not limited here.

[0316] In this embodiment, the terminal device sends the maximum aggregated spectrum supported by the terminal device within a first range to the network device. This maximum aggregated spectrum is less than the sum of the maximum bandwidths of all aggregated carriers supported by the terminal device within the first range. This avoids the need for the terminal device to design capabilities based on the maximum bandwidth of all supported aggregated carriers when designing its supported capabilities. The greater the capability supported by the first device, the higher the corresponding cost. Therefore, by reporting the capability information using the method provided in this embodiment, excessive capabilities can be avoided during the design phase of the first device, thus reducing its cost.

[0317] like Figure 4 The diagram shown is a flowchart illustrating another capability information reporting method according to an embodiment of this application.

[0318] It should be noted that, in this embodiment, when the first terminal device reports capability information to the network device, the first terminal device is referred to as the first device, and the network device is referred to as the second device. When the first terminal device receives capability information sent by the second terminal device, the first terminal device is referred to as the second device, and the second terminal device is referred to as the first device.

[0319] In step 401, the first terminal device determines the capability information.

[0320] In step 402, the first terminal device sends capability information to the network device.

[0321] In step 403, the network device determines the first frequency domain resources within the first range based on the first capability information.

[0322] In step 404, the network device sends the first scheduling information to the first terminal device.

[0323] In step 405, the first terminal device determines the spectrum processing resources based on the first scheduling information.

[0324] Steps 401 to 405 in this embodiment are the same as those described above. Figure 2 Steps 201 to 205 are similar and will not be described in detail here.

[0325] In step 406, the second terminal device sends target capability information to the first terminal device.

[0326] In special scenario modes, the second terminal device needs to send the target capability information of the second terminal device to the first terminal device. This target capability information is used to enable the first terminal device and the second terminal device to communicate directly.

[0327] In one possible implementation, in idle or inactive mode, the second terminal device and the first terminal device can communicate directly through the PC5 interface using mode 2 resources. However, in this case, the first terminal device is already communicating with the network device. Therefore, the second terminal device needs to send its target capability information to the first terminal device. The first terminal device can then communicate with the second terminal device by avoiding subframes that receive messages from the network device and / or send messages to the network device, based on the indication of the second terminal device's target capability information.

[0328] It is understandable that in many other scenarios, the second terminal device sends target capability information to the first terminal device, such as in V2X scenarios, but these will not be elaborated on here.

[0329] In this embodiment, the method by which the second terminal device determines the target capability information is similar to the method by which the first terminal device determines the capability information in step 401, and will not be described in detail here.

[0330] In step 407, the first terminal device determines the target spectrum processing resources based on the target capability information.

[0331] After receiving the target capability information sent by the second terminal device, the first terminal device determines the target spectrum processing resources that can be used for communication with the second terminal device based on the target capability information.

[0332] After determining the target spectrum processing resources, the first terminal device updates its capability information and generates a fourth indication information, which indicates that the capability information of the first terminal device has changed.

[0333] In step 408, the first terminal device sends a fourth instruction message to the network device.

[0334] In step 409, the network device determines the second frequency domain resources based on the fourth instruction information.

[0335] In step 410, the network device sends the second scheduling information to the first terminal device.

[0336] In this embodiment, steps 408 to 410 and Figure 3 Steps 306 to 308 in the embodiment are similar, and will not be described in detail here.

[0337] In step 411, the first terminal device determines the second spectrum processing resource based on the second scheduling information.

[0338] After receiving the second scheduling information, the first terminal device determines the second frequency domain resources configured by the network device based on the second scheduling information. After determining the second frequency domain resources, the first terminal device determines the second spectrum processing resources of the first terminal device based on the second frequency domain resources.

[0339] In one possible implementation, the first terminal device determines the carriers effective within the updated first range based on the second frequency domain resources, and configures the corresponding second spectrum processing resources according to the effective carriers. For example, if the second frequency domain resources indicate that the network device has activated two carriers, carrier 1 and carrier 2, with bandwidths of 20MHz and 40MHz respectively, then the terminal device allocates 20MHz and 40MHz of spectrum processing resources to carrier 1 and carrier 2 respectively.

[0340] For example, in the second frequency domain resources, the network device configures two carriers for the first terminal device. Carrier 1 is in frequency band A with a maximum BWP of 40MHz, and carrier 2 is in frequency band B with a maximum BWP of 60MHz. Then, the first terminal device allocates 40MHz of spectrum processing resources to carrier 1 and 60MHz of spectrum processing resources to carrier 2.

[0341] It should be noted that the sum of the target spectrum processing resources used for communication between the first terminal device and the second terminal device and the second spectrum processing resources used for communication between the first terminal device and the network device does not exceed the total spectrum processing resources of the first terminal device.

[0342] In one possible implementation, after determining the second frequency domain resource, if the first terminal device learns that the spectrum simultaneously received and / or transmitted within the updated first range indicated by the second frequency domain resource exceeds the maximum aggregated spectrum supported by the first terminal device within the updated first range, then the first terminal device determines that the second scheduling information is incorrect. The first terminal device may discard the second scheduling information or send a prompt indicating that the second scheduling information is incorrect to the network device. It is understood that the first terminal device may also, based on its maximum supported aggregated spectrum, not receive and / or not transmit the data corresponding to the portion of the spectrum in the first frequency domain resource that exceeds the maximum aggregated spectrum, but this is not specifically limited here.

[0343] In this embodiment, the first terminal device may explicitly carry the updated first range information in the fourth indication information, or it may not carry the updated first range information in the fourth indication information, but only carry the indication update message. After receiving the indication update message sent by the first terminal device, the network device will send a query message to the first terminal device. The query message is used to query the updated capability information of the first terminal device. Alternatively, the first terminal device may also send the updated first range information to the network device through the first terminal device assisted information (UE assisted information). The specific method is not limited here.

[0344] In this embodiment, the first terminal device can share its spectrum processing resources across different carriers, thus saving costs for the first terminal device.
