Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a communication method and apparatus. Background Technology

[0002] In current mobile communication systems, the peak data transmission rate of the air interface depends on the number of data layers, modulation order, code rate, scheduling bandwidth, and system redundancy (overhead) value.

[0003] The redundancy value currently used for peak rate calculation is a fixed value related to the transmission direction and frequency band. This redundancy measure is an average value calculated based on the system's average redundancy. Even if the terminal supports a lower redundancy, the base station can only schedule data according to this fixed redundancy value, resulting in the instantaneous peak throughput of the air interface not reaching the maximum throughput supported by the terminal. In other words, existing technology also uses this redundancy to limit the maximum instantaneous scheduling rate during scheduling, causing the average redundancy to become the lowest redundancy for scheduling, resulting in the actual average peak rate being lower than the expected peak rate. Taking the 3rd generation partnership project (3GPP) New Radio (NR) system as an example, 3GPP 38.306 supports a redundancy value of not less than 0.14. Taking the following example, even if the redundancy of the currently scheduled PDSCH is less than 0.14, for example, only 0.07, the base station can only constrain the number of information bits that can be carried according to a redundancy of 0.14, resulting in a decrease in the instantaneous peak throughput of the air interface. Summary of the Invention

[0004] This application provides a communication method and apparatus to improve air interface peak throughput.

[0005] In a first aspect, embodiments of this application provide a communication method that can be executed by a terminal device or a component (such as a processor, chip, or chip system) in the terminal device.

[0006] The following description uses a terminal device as the executing entity. According to this method, the terminal device can determine first capability information, which indicates that the transmission rate supported by the terminal device meets a rate condition, or the first capability information can be used to indicate that the redundancy supported by the terminal device is less than a set redundancy. The terminal device can also send the first capability information to the network device.

[0007] The rate condition includes one or more of the following conditions: the transmission rate supported by the terminal device exceeds a first data rate, which is related to a set redundancy; or, the transmission rate supported by the terminal device for a single carrier scheduling exceeds a second data rate, which is related to a set redundancy; or, the sum of the transmission rates of the serving cells supported by the terminal device in all frequency band combinations within the scheduled frequency range exceeds a third data rate, which is related to a set redundancy.

[0008] Using the above method, the terminal device can report its capabilities to the network device based on its own capabilities. This allows the network device to know that the terminal device supports a higher peak data rate than the peak data rate determined by the set redundancy, or to know that the terminal device supports a lower redundancy than the set redundancy. As a result, the network device can schedule the terminal device's data according to a lower redundancy than the set redundancy, instead of scheduling according to the set redundancy as in existing technologies, thereby improving network throughput.

[0009] In one possible design, the terminal device may also receive scheduling information from the network device. This scheduling information may correspond to a maximum data rate exceeding a first data rate; or, the scheduling information may correspond to a single carrier scheduling transmission rate exceeding a second data rate; or, the scheduling information may correspond to the sum of the transmission rates of serving cells within all frequency band combinations in the scheduled frequency range, exceeding a third data rate, which is related to a set redundancy.

[0010] This design can improve the peak rate of a single carrier in single-carrier and / or non-full-carrier aggregation scheduling scenarios.

[0011] In one possible design, the first capability information is used to instruct the terminal device to support the transmission rate across the entire frequency band range; or, the first capability information is used to instruct the terminal device to support the transmission rate within one or more frequency ranges supported by the terminal device; or, the first capability information is used to instruct the terminal device to support the transmission rate within one or more frequency band combinations supported by the terminal device; or, the first capability information is used to instruct the terminal device to support the transmission rate within one or more frequency bands supported by the terminal device; or, the first capability information is used to instruct the terminal device to support the transmission rate on one or more carriers supported by the terminal device.

[0012] With this design, the terminal device can flexibly report whether it supports a transmission rate that meets the rate conditions and whether it supports a redundancy of less than the set redundancy within the frequency range applicable to the first capability information. It can also support scheduling methods based on different redundancy in different frequency ranges to achieve flexible scheduling.

[0013] In one possible design, the first capability information includes uplink first capability information and / or downlink first capability information. The uplink first capability information is used to indicate that the uplink transmission rate supported by the terminal device meets the rate condition, or to indicate that the uplink redundancy supported by the terminal device is less than a set redundancy. The uplink first capability information is also used to indicate that the downlink transmission rate supported by the terminal device meets the rate condition, or to indicate that the downlink redundancy supported by the terminal device is less than a set redundancy.

[0014] With this design, the terminal device can report the first capability information according to the uplink and downlink transmissions respectively, thereby flexibly reporting whether the uplink and downlink transmissions support the transmission rate that meets the rate conditions and whether they support the redundancy of less than the set redundancy. It supports the use of different redundancy-based scheduling methods for uplink and downlink transmissions to achieve flexible scheduling.

[0018] In one possible design, the network device may also send scheduling information to the terminal device based on the first capability information, or in other words, the network device may send scheduling information to the terminal device in response to the first capability information. Wherein, the maximum data rate corresponding to the scheduling information exceeds the first data rate; or, the transmission rate of a single carrier scheduled according to the scheduling information exceeds the second data rate; or, the sum of the transmission rates of the serving cells within all frequency band combinations in the scheduled frequency range corresponding to the scheduling information exceeds a third data rate, which is related to a set redundancy.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The specific operating methods in the method embodiments can also be applied to the device embodiments or system embodiments.

[0050] like Figure 1 As shown, the measurement feedback method provided in this application embodiment can be applied to a wireless communication system, which may include a terminal device 101 and a network device 102.

[0051] It should be understood that the above wireless communication systems are applicable to both low-frequency (sub-6G) and high-frequency (above-6G) scenarios. Application scenarios for these wireless communication systems include, but are not limited to, fifth-generation systems, new radio (NR) communication systems, or future evolved public land mobile network (PLMN) systems.

[0052] The terminal device 101 shown above can be user equipment (UE), terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication equipment, terminal agent, or terminal equipment, etc. This terminal device 101 may have wireless transceiver capabilities, enabling it to communicate (e.g., wirelessly) with one or more network devices in one or more communication systems, and to receive network services provided by the network devices. These network devices include, but are not limited to, the network device 102 shown in the figure.

[0053] Among them, terminal device 101 may be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA) device, handheld device with wireless communication function, computing device or other processing device connected to a wireless modem, vehicle device, wearable device, terminal device in future 5G network or terminal device in future evolved PLMN network, etc.

[0054] Furthermore, terminal device 101 can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; terminal device 101 can also be deployed on water (such as on ships); terminal device 101 can also be deployed in the air (such as on airplanes, balloons, and satellites). Specifically, terminal device 101 can be a mobile phone, tablet, computer with wireless transceiver capabilities, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. Terminal device 101 can also be a communication chip with a communication module, a vehicle with communication capabilities, or in-vehicle equipment (such as in-vehicle communication devices, in-vehicle communication chips), etc.

[0055] Network device 102 can be an access network device (or access point). Access network device refers to equipment that provides network access functionality, such as a radio access network (RAN) base station. Specifically, network device 102 may include a base station (BS), or a base station and radio resource management equipment used to control the base station. Network device 102 may also include relay stations (relay equipment), access points, and base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations. Network device 102 can be a wearable device or an in-vehicle device. Network device 102 can also be a communication chip with a communication module.

[0056] For example, network device 102 includes, but is not limited to: next-generation base stations (g node B, gNB) in 5G, evolved node B (eNB) in LTE systems, radio network controllers (RNCs), radio controllers in CRAN systems, base station controllers (BSCs), home base stations (e.g., home evolved node B, or home node B, HNB), baseband units (BBUs), transmitting and receiving points (TRPs), transmitting points (TPs), or mobile switching centers. Network device 102 may also include base stations in future 6G or later mobile communication systems. It should be understood that network device 102 may also be a scheduling node or a component of a scheduling node with scheduling capabilities, such as a terminal.

[0057] based on Figure 1 In the architecture shown, network device 102 can schedule uplink and / or downlink air interface data transmission of terminal device 101. The air interface data transmission rate (or data rate, transmission rate, or rate) depends on the number of data layers, modulation order, code rate, scheduled bandwidth, and system overhead. Taking 3GPP NR as an example, the peak rate of the terminal device specified in 3GPP 38.306 is defined by the following formula:

[0058] Formula (1);

[0059] The unit of this rate is megabits per second (Mbps). J It refers to the number of component carriers within a frequency band or a combination of frequency bands. This represents each frequency band or each combination of frequency bands. =1, 2... J . R max = 948 / 1024, representing the maximum coding rate.

[0060] Furthermore, in formula (1), This indicates that the higher layer is configured with a component carrier (CC). The maximum number of supported layers. Indicates high-level configuration of component carrier The maximum supported modulation order. Component carriers configured for higher layers The linear scaling factor has a value of 1, 0.8, 0.75 or 0.4. For the values ​​corresponding to the subcarrier spacing, The value can be 0, 1, 2 or 3, corresponding to 15 kHz, 30 kHz, 60 kHz and 120 kHz subcarrier spacing, respectively. To and The corresponding length of the average orthogonal frequency-division multiplexing (OFDM) symbol within a subframe, where, . Component carrier Redundancy measurement. To and Corresponding component carrier channel bandwidth The largest number of resource blocks (RBs) within.

[0061] For downlink transmission within the frequency range FR1, =0.14; For uplink transmission within the frequency range FR1, =0.18; For downlink transmission within the frequency range FR2, =0.08; For uplink transmission within the frequency range FR2, =0.10. It should be understood that the above definition may be used in this application. =0.14 is called the set redundancy. In the 3GPP protocol, the definitions of frequency ranges FR1 and FR2 are as follows.

[0062]

[0063] Table 1

[0064] It should be understood that in this application, [the following can be used]: =0.14 is called the set redundancy of FR1 downlink transmission, or, can be... =0.08 is called the set redundancy for FR2 downlink transmission. This is understandable. =0.14 is the set redundancy in FR1 downlink transmission, and the corresponding data rate (i.e., the data rate determined according to 0.14) is the first data rate in FR1 downlink transmission. Accordingly, =0.18 is the set redundancy in FR1 uplink transmission. The data rate corresponding to this set redundancy is the first data rate in FR1 uplink transmission. =0.08 is the set redundancy in FR2 downlink transmission. The data rate corresponding to this set redundancy is the first data rate in FR2 downlink transmission. =0.10 represents the set redundancy in FR2 downlink transmission. The data rate corresponding to this set redundancy is the first data rate in FR2 uplink transmission. For simplicity, this application uses FR1 downlink transmission as an example for explanation. It can be understood that the set redundancy and the first data rate have different values ​​in different frequency ranges and different transmission directions.

[0065] For example, taking downlink transmission in frequency range FR1 with a maximum single-carrier bandwidth of 100 MHz as an example, the air interface peak rate is shown in the table below.

[0066]

[0067] Table 2

[0068] It should be understood that, according to the prior art, the peak rate of data transmitted over the air interface by network device 102 and terminal device 101 does not exceed the terminal peak rate defined by formula (1).

[0069] Furthermore, based on formula (1), the scheduling of a transmission block of a carrier by network device 102 for terminal device 101 satisfies the following formula (2):

[0070] Formula (2);

[0071] in, This represents the maximum data rate supported by the terminal device for one carrier of one serving cell in one frequency band, calculated according to formula (1). This rate may be referred to as the transmission rate of a single carrier in this application, and its unit is Mbps.

[0072] L It is the number of time-domain symbols of the scheduled physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH). M It is the number of transport blocks (TB) of PDSCH or PUSCH. For each symbol, the time domain time is, where, The subcarrier spacing is represented digitally for PDSCH or PUSCH. If the subcarrier spacing is 15kHz, then... =0, if the subcarrier spacing is 30kHz, then =1, if the subcarrier spacing is 60kHz, then =2, if the subcarrier spacing is 120kHz, then =3, if the subcarrier spacing is 240kHz, then =4, if the subcarrier spacing is 480kHz, then =5, etc.

[0073] The m-th TB, Where: A is the number of bits in this transport block, and C is the total number of code blocks in the transport block. This represents the number of code blocks scheduled for the transport block. This indicates rounding down to the nearest integer.

[0074] It should be understood that in this application, [the following can be used]: =0.14 is called the set redundancy, and the value is determined based on this redundancy. This can be referred to as the second data rate.

[0075] Based on formula (1), during multi-carrier scheduling, the overall scheduling of network device 102 for terminal device 101 within a cell group must satisfy the following formula (3):

[0076] Formula (3);

[0077] in, The maximum value of the sum of the data rates of the serving cells in all frequency band combinations supported by the terminal device within a frequency band range, calculated according to formula (1), is referred to in this application as the sum of the transmission rates of the serving cells in all frequency band combinations within the scheduled frequency range of the terminal device, and its unit is Mbps.

[0078] J This refers to the number of cells configured within the frequency range of the cell group (in this application, "cell" has the same meaning as "carrier"). For the... One community, M In time slot s j The number of TB of PDSCH or PUSCH transmitted. =10 -3 / 2 (j) For the first The cell is in time slot s j The time of each symbol, in the time domain. ( ) is the first The cell is in time slot s j The subcarrier spacing is represented digitally; if the subcarrier spacing is 15kHz, then... ( If the subcarrier spacing is 30kHz, then ) = 0. ( If the subcarrier spacing is 60kHz, then )=1. ( =2, if the subcarrier spacing is 120kHz, then ( If the subcarrier spacing is 240kHz, then )=3, ( =4, if the subcarrier spacing is 480kHz, then ( =5, etc.

[0079] The m-th TB, Where: A is the number of bits in this transport block, and C is the total number of code blocks in the transport block. This represents the number of code blocks scheduled for the transport block.

[0080] It should be understood that in this application, [the following can be used]: =0.14 is called the set redundancy, and the value is determined based on this redundancy. It can be referred to as the third data rate.

[0081] Currently, the redundancy metric used in peak rate calculation according to formula (1) is... It is a fixed value related to the transmission direction and transmission frequency band. This redundancy measure is the average value calculated based on the average redundancy of the system. However, the existing technology requires each scheduling to satisfy formula (2) and formula (3). Thus, taking the following as an example, even if the redundancy of the currently scheduled PDSCH is less than 0.14, such as only 0.07 (or 1 / 14), the number of information bits that can be carried can only be constrained according to the redundancy of 0.14, resulting in a decrease in the instantaneous peak throughput of the air interface. For example, according to the original intention of 5G NR design, the highest code rate of NR can be 948 / 1024=0.93. That is to say, a physical layer RB can have a maximum of 156 resource elements (REs) to carry information bits, and the maximum number of information bits that can be carried is 1155 bits. However, due to the constraints of formula (2) and formula (3), a RB can only have a maximum of 144 REs to carry information bits, and the maximum number of information bits that can be carried is 1066, and the code rate is reduced to only 0.85, thereby reducing the network throughput.

[0082] To improve the throughput of open-loop transmission, embodiments of this application provide a communication method. This communication method can be implemented by a terminal device and a network device; specifically, the terminal device may include… Figure 1 The terminal device 101 shown may include network device 102 as shown in Figure 1.

[0083] like Figure 2 As shown, the method provided in this application embodiment includes the following steps:

[0084] S101: The terminal device determines the first capability information.

[0085] In one possible example, the first capability information is used to indicate that the transmission rate supported by the terminal device meets the rate condition.

[0086] The rate condition includes at least one of the following three conditions: Condition 1, the transmission rate supported by the terminal device exceeds the first data rate; Condition 2, the transmission rate supported by the terminal device for a single carrier scheduling exceeds the second data rate; Condition 3, the sum of the transmission rates of the serving cells supported by the terminal device in all frequency band combinations within the scheduled frequency range exceeds the third data rate.

[0087] For example, the first capability information is used to indicate that the terminal device supports a transmission rate exceeding a first data rate, and that the terminal device supports a single carrier-based transmission rate exceeding a second data rate, and that the terminal device supports a transmission rate exceeding a third data rate for serving cells within all frequency band combinations in the scheduled frequency range. Alternatively, the first capability information is used to indicate that the terminal device supports a single carrier-based transmission rate exceeding a second data rate, and that the terminal device supports a transmission rate exceeding a third data rate for serving cells within all frequency band combinations in the scheduled frequency range. Alternatively, the first capability information is used to indicate that the terminal device supports a single carrier-based transmission rate exceeding a second data rate.

[0088] Furthermore, the first capability information is also used to indicate that the transmission rate of a single carrier supported by the terminal device does not exceed the sum of the transmission rates of serving cells within all frequency band combinations in the scheduled frequency range, and that the sum of the transmission rates of serving cells within all frequency band combinations in the scheduled frequency range does not exceed the transmission rate supported by the terminal device. Here, the single carrier is the carrier of a serving cell within the scheduled frequency range, and the entire frequency band group within the scheduled frequency range is the frequency band combination supported by the terminal device. In other words, the second data rate determined based on the single carrier does not exceed the third data rate determined based on multiple carriers including the single carrier, and the third data rate does not exceed the first data rate.

[0089] It should be understood that the rate condition includes at least one of the three conditions mentioned above, which can improve the peak rate of a single carrier under single-carrier and / or non-full-carrier aggregation scheduling conditions without increasing the total terminal cost.

[0090] The first data rate includes the peak rate determined according to formula (1), which is determined based on a set redundancy, for example, a redundancy of 0.14. The second data rate includes the peak transmission rate of a single carrier scheduling determined according to formula (2), which is determined based on a set redundancy, for example, a redundancy of 0.14. The third data rate includes the first capability information of the configured serving cell within all frequency band combinations supported by the terminal device in a frequency band range, determined according to formula (3), which is used to indicate the peak data rate, and the third data rate is determined based on a set redundancy, for example, a redundancy of 0.14.

[0091] For example, a terminal device can determine its maximum supported transmission rate based on factory configuration and other information. When the maximum supported transmission rate exceeds the first data rate, it is determined that the rate condition is met. Similarly, a terminal device can determine its maximum supported transmission rate for a single carrier and / or the maximum supported transmission rate of the serving cell within all frequency band combinations in the scheduled frequency range based on factory configuration and other information.

[0092] Furthermore, the first data rate, the second data rate, and the third data rate mentioned above can be calculated by the terminal device according to the above formula, or can be calculated by the network device according to the above formula and then informed to the terminal device, or can be obtained by the terminal device based on factory configuration and other information.

[0093] In another possible example, the first capability information can be used to indicate that the redundancy supported by the terminal device is less than the set redundancy.

[0094] For example, if the redundancy is set to 0.14 and the terminal device supports a redundancy of 0.07, then the first capability information can indicate this redundancy, or indicate that the redundancy supported by the terminal device is less than 0.14.

[0095] For example, the first capability information can be used to indicate that the redundancy supported by the terminal device is less than a set redundancy. Further, the first capability information can indicate one or more of the following three redundancy conditions: Condition 1, the redundancy supported by the terminal device is less than the set redundancy when the terminal device calculates the peak rate according to formula (1); Condition 2, the redundancy supported by the terminal device is less than the set redundancy when the terminal device calculates the peak transmission rate of a single carrier scheduling according to formula (2); Condition 3, the redundancy supported by the terminal device is less than the set redundancy when the terminal device calculates the transmission rate of the serving cell in all frequency band combinations within the scheduled frequency range supported by the terminal device according to formula (3).

[0096] For example, the first capability information indicates that the terminal device adopts a set redundancy of 0.14 when determining the peak rate according to formula (1), the redundancy supported by the terminal device is less than the set redundancy when calculating the peak transmission rate of a single carrier according to formula (2), and the redundancy supported by the terminal device is less than the set redundancy when calculating the transmission rate of the serving cell in all frequency band combinations within the frequency range to which the terminal device is scheduled according to formula (3).

[0097] It should be understood that the first capability information is used to indicate one or more of the three redundancy conditions, which can improve the peak rate of a single carrier in single-carrier and / or non-full-carrier aggregation scheduling scenarios without increasing the total terminal cost.

[0098] For example, the redundancy supported by the terminal device can be determined by the terminal device based on factory configuration and other information. The redundancy setting can be determined by the terminal device based on factory configuration and other information, or it can be sent to the terminal device by the network device.

[0099] S102: The terminal device sends the first capability information to the network device.

[0100] For example, the first capability information may be carried in the capability information and sent to the network device.

[0101] Accordingly, network devices can receive this first capability information.

[0102] use Figure 2 The method allows the terminal device to report its capabilities to the network device, enabling the network device to know that the terminal device supports a higher peak data rate than the peak data rate determined by the set redundancy, or to know that the terminal device supports a lower redundancy than the set redundancy. This allows the network device to schedule the terminal device's data according to a lower redundancy than the set redundancy, instead of scheduling it according to the set redundancy as in existing technologies, thereby improving network throughput.

[0103] Taking a redundancy value of 0.14 as an example, and based on the terminal device supporting a redundancy of 0.07, the prevention rate supported by the terminal device according to formula (1) is shown in Table 3.

[0104]

[0105] Table 3

[0106] As can be seen from Table 2, when the terminal device supports a lower redundancy value, it means that the terminal device can support a higher peak rate, thus improving the air interface data throughput.

[0107] When a terminal device supports a lower redundancy value for a single carrier, such as 0.07, but the terminal's peak rate still maintains the set redundancy, such as 0.14, then, combining Tables 2 and 3, in a scenario where the terminal supports two carriers, the terminal's peak rate remains unchanged at 4.7Gbps. Therefore, the terminal's cost and complexity do not increase. However, when the terminal is only scheduled for one carrier, the rate of that single carrier can be scheduled to 2.54Gbps. Compared to the existing technology, which has a single carrier rate of 2.35Gbps in this case, the air interface data throughput is improved by 0.19Gbps.

[0108] like Figure 3 As shown, after step S102, step S103 can also be performed. In S103, the network device can send scheduling information to the terminal device according to the terminal device's first capability information. This scheduling information can be used to schedule the terminal device's data. Specifically, the maximum data rate corresponding to the scheduling information exceeds the first data rate, or the transmission rate of a single carrier scheduled according to the scheduling information exceeds the second data rate, or the sum of the transmission rates of the serving cells within all frequency band combinations in the scheduled frequency range corresponding to the scheduling information exceeds the third data rate. The first, second, and third data rates are explained in S101.

[0109] For example, if the transmission rate supported by the terminal device does not meet the rate condition, and the redundancy supported by the terminal device is not less than the set redundancy, then the scheduling sent by the network device to the terminal needs to satisfy formula (2) and formula (3). If the transmission rate supported by the terminal device meets the rate condition, or the redundancy supported by the terminal device is less than the set redundancy, then the redundancy of the scheduling sent by the network device to the terminal device can be the redundancy supported by the terminal, for example, 0.07, which is 1 / 14. In this case, the scheduling sent by the network device to the terminal needs to satisfy the rate condition calculated by formula (2) and / or formula (3) with 0.07 as the redundancy, instead of the rate condition calculated by formula (2) and / or formula (3) with 0.14 as the redundancy in the prior art.

[0110] Accordingly, terminal devices and network devices can transmit data based on this scheduling information, thereby achieving higher data throughput.

[0111] Taking downlink (DL) transmission as an example, when the redundancy of network device scheduling is reduced from 0.14 to 0.07, as shown in Table 4, the throughput can be increased by 190Mbps at 100MHz and by 380Mbps at 200MHz.

[0112]

[0113] Table 4

[0114] In one possible implementation of S102, the terminal device can report first capability information through the indication information of the linear scaling parameter. Specifically, when the linear scaling parameter indicated by the capability information reported by the terminal device is not less than 1, it indicates that the transmission rate supported by the terminal device meets the rate condition, or that the redundancy supported by the terminal device is less than the set redundancy. For example, for FR1, when the linear scaling parameter is 1.08, it means that the transmission rate supported by the terminal device meets the rate condition, or that the redundancy supported by the terminal device is less than the set redundancy; for FR2, when the linear scaling parameter is 1, it means that the transmission rate supported by the terminal device meets the rate condition, or that the redundancy supported by the terminal device is less than the set redundancy.

[0115] In another possible implementation of S102, the terminal device can report the first capability information through a new field in the capability information. For example, when the capability information reported by the terminal device carries a newly defined field, and the newly defined field indicates "support", it means that the transmission rate supported by the terminal device meets the rate condition, or it indicates that the redundancy supported by the terminal device is less than the set redundancy.

[0116] For example, the first capability information above may also indicate the frequency range that the terminal device supports.

[0117] Specifically, the first capability information may indicate that the terminal device supports the transmission rate across all frequency bands (the transmission rate being the transmission rate supported by the terminal device), or indicate that the terminal device supports the redundancy across all frequency bands (the redundancy being the redundancy supported by the terminal device).

[0118] For example, primary capability information may also include fields supporting the entire frequency band range.

[0119] Similarly, the first capability information can instruct the terminal device to support the transmission rate within one or more frequency ranges supported by the terminal device, or to support the redundancy within one or more frequency ranges supported by the terminal device; the first capability information can instruct the terminal device to support the transmission rate within one or more frequency band combinations supported by the terminal device, or to support the redundancy within one or more frequency band combinations supported by the terminal device; the first capability information can instruct the terminal device to support the transmission rate within one or more frequency bands supported by the terminal device, or to support the redundancy within one or more frequency bands supported by the terminal device; the first capability information can instruct the terminal device to support the transmission rate within one or more frequency bands within one or more frequency band combinations supported by the terminal device, or to support the redundancy within one or more frequency band combinations supported by the terminal device; the first capability information can instruct the terminal device to support the transmission rate within one or more carriers of one or more frequency bands within one or more frequency band combinations supported by the terminal device, or to support the redundancy within one or more carriers supported by the terminal device.

[0120] For example, the first capability information can correspond to a frequency band range (or a combination of frequency bands, a frequency band, or a carrier). When the terminal device supports multiple frequency band ranges (or combinations of frequency bands, a frequency band, or a carrier), the terminal device can report the first capability information separately according to the multiple frequency band ranges (or combinations of frequency bands, a frequency band, or a carrier). According to this design, the reporting of first capability information at different granularities can be achieved according to the frequency range to support a more flexible scheduling method.

[0121] For example, if the terminal device supports the following bands: FR1 band A, FR1 band B, and FR2 band C. Band A has 2 component carriers, band B has 3 component carriers, and band C has 4 component carriers. The terminal device supports only the combinations of band A and band B, and the combinations of band A, band B, and band C.

[0122] When the first capability indicates that the terminal device supports the redundancy of 0.07 in all frequency bands, it means that the redundancy is 0.07 for all scenarios of the terminal device. That is to say, when calculating the transmission rate according to formula (1), formula (2) and formula (3), the redundancy is calculated as 0.07.

[0123] When the first capability indicates that the terminal supports the redundancy of 0.07 in one or more frequency ranges supported by the terminal device, for example, it can indicate that redundancy of 0.07 is not supported in FR1, but is supported in FR2. Then, when the network device and the terminal device calculate the transmission rate of FR1 according to formulas (1), (2) and (3), they calculate it according to redundancy of 0.14, and when the network device and the terminal device calculate the transmission rate of FR2 according to formulas (1), (2) and (3), they calculate it according to redundancy of 0.07.

[0124] When the first capability indicates that the terminal supports the redundancy of 0.07 within one or more frequency combinations supported by the terminal device, for example, the redundancy of 0.07 is supported in the carrier aggregation of band A and band B, but not in the carrier aggregation of band A, band B, and band C. Then, when the network device and the terminal device calculate the transmission rate of the carrier aggregation of band A and band B according to formulas (1), (2), and (3), they calculate it according to the redundancy of 0.07. When the network device and the terminal device calculate the transmission rate of the carrier aggregation of band A, band B, and band C according to formulas (1), (2), and (3), they calculate the transmission rate of FR1 according to the redundancy of 0.14 and the transmission rate of FR2 according to 0.08.

[0125] When the first capability indicates that the terminal supports the redundancy of 0.07 in one or more frequency bands within one or more frequency combinations supported by the terminal device, for example, in the carrier aggregation of band A and band B, band A supports the redundancy of 0.07, but band B in the carrier aggregation of band A and band B does not support the redundancy of 0.07, then when the network device and the terminal device calculate the transmission rate of the carrier aggregation of band A and band B according to formulas (1), (2) and (3), the transmission rate corresponding to band A is calculated with a redundancy of 0.07, and the transmission rate corresponding to band B is calculated with a redundancy of 0.14.

[0126] When the first capability indicates that the terminal supports the redundancy of 0.07 in one or more carriers of one or more frequency bands within one or more frequency band combinations supported by the terminal device, for example, if the redundancy of 0.07 is supported in component carrier 1 of band A but not in component carrier 1 of band B, then when the network device and the terminal device calculate the transmission rate according to formula (1), formula (2) and formula (3), the transmission rate corresponding to component carrier 1 of band A is calculated according to the redundancy of 0.07, and the transmission rate corresponding to component carrier 1 of band B is calculated according to the redundancy of 0.14.

[0127] Furthermore, the first capability information may include uplink first capability information and / or downlink first capability information. The uplink first capability information can be used to indicate that the uplink transmission rate supported by the terminal device meets the aforementioned rate condition, or to indicate that the uplink redundancy supported by the terminal device is less than a set redundancy. The downlink first capability information can be used to indicate that the downlink transmission rate supported by the terminal device meets the aforementioned rate condition, or to indicate that the downlink redundancy supported by the terminal device is less than a set redundancy.

[0128] When the first capability information includes uplink first capability information, the network device can determine uplink scheduling information based on the uplink first capability information to improve uplink data transmission throughput. When the first capability information includes downlink first capability information, the network device can determine downlink scheduling information based on the downlink first capability information to improve downlink data transmission throughput. According to this design, more flexible first capability information reporting based on uplink and downlink can be achieved to support more flexible scheduling methods.
