Description

Information transmission method, device, equipment, chip and storage medium Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and specifically to an information transmission method, apparatus, device, chip, and storage medium. Background Art

[0002] In the current 5G system, when a terminal is configured with multiple frequency bands at the same time and the terminal can support different frequency band combinations composed of the multiple frequency bands in a time-sharing manner, the terminal can report a communication capability for each of the multiple frequency bands, without considering that the communication capability of the terminal on each frequency band may change with different frequency band combinations (matching) methods.

[0003] For example, the terminal can be configured with frequency band #1, frequency band #2 and frequency band #3 at the same time. Assuming that the terminal can support [frequency band #1, frequency band #2] (that is, the terminal can communicate on frequency band #1 and frequency band #2 at the same time) and [frequency band #1, frequency band #3] (that is, the terminal can communicate on frequency band #1 and frequency band #3 at the same time) in a time-sharing manner, but the terminal cannot communicate on frequency band #1, frequency band #2 and frequency band #3 at the same time, in this scenario, the terminal will report a communication capability for frequency band #1, frequency band #2 and frequency band #3 respectively, without considering the situation that the terminal's communication capability on frequency band #1 may change with the combination with frequency band #2 and frequency band #3.

[0004] This may cause the reported communication capability on a certain frequency band to exceed the capability range of the terminal when paired with a different frequency band, or fail to fully reflect the maximum capability of the terminal.

It should also be understood that in the embodiments of the present application, the “protocol” may refer to a standard protocol in the field of communications, such as LTE protocols, NR protocols, and related protocols used in future communication systems, and the present application does not limit this.

[0048] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0049] 1. Protocol stack architecture

[0050] In the 5G system, with a dual-connectivity architecture, the protocol stacks of the user plane and control plane are relatively complex.

[0051] In a dual-connectivity architecture, the network consists of two nodes: a master node (MN) and a secondary node (SN). The Packet Data Convergence Protocol (PDCP) and Service Data Adaptation Protocol (SDAP) protocol stacks, as well as the corresponding protocol stacks below PDCP (i.e., radio link control (RLC), media access control (MAC), and physical layer (PHY)), may be located in different network nodes. There is no problem of distinguishing different nodes within the terminal, but there is the issue of cell group roles, namely the need to distinguish between the master cell group (MCG) and the secondary cell group (SCG). The difference between the MCG and SCG comes from the different protocol layers (i.e., MAC and PHY) of different radio bearer aggregation.

[0052] Figure 2 shows the network-side radio bearer structure for E-UTRA NR Dual Connectivity (EN-DC). When the RLC, MAC, and PHY protocol stacks of a radio bearer are located in the mobile node, it is called an MCG bearer; otherwise, it is called an SCG bearer. A split bearer has radio links on both the mobile node and the network node, but only a single PDCP protocol stack. This PDCP protocol stack can be located in either the mobile node or the network node. Split bearers are designed to improve radio interface throughput.

[0053] 2. Carrier Aggregation

[0054] Each cell group can support one or more cells to support carrier aggregation (CA). In CA, two or more component carriers (CCs) are aggregated. A terminal (UE) can simultaneously receive or transmit on one or more CCs based on its capabilities.

[0055] A UE with CA single timing advance (TA) capability can simultaneously receive and / or transmit on multiple CCs corresponding to multiple serving cells sharing the same timing advance (multiple serving cells are grouped into one TAG); a UE with CA multiple timing advance capability can simultaneously receive and / or transmit different timing advances on multiple CCs corresponding to multiple serving cells (multiple serving cells are grouped into multiple TA groups (TAGs)).

[0056] The maximum number of CCs configured for a UE is: 16 for downlink (DL) and 16 for uplink (UL).

[0057] 3. Cell and Band Width Part (BWP)

[0058] From the perspective of frequency domain energy conservation, 5G introduces the BWP function. NR's carrier bandwidth is significantly larger than LTE, and many core frequency bands can support a typical 100MHz carrier bandwidth. The advantage of large bandwidth is that it can achieve high transmission rates. However, if the service mode is to transmit small amounts of data, or when the service is discontinuous, it is very uneconomical for the UE to operate in large bandwidth mode. The core of BWP is to define a bandwidth that is smaller than both the cell's carrier bandwidth and the terminal's bandwidth capability. When the amount of data transmitted on the air interface is relatively low, the terminal operates within a smaller bandwidth for transmission and reception under dynamic configuration on the network side. This allows the terminal's RF front-end components, RF transceiver, and baseband signal processing module to operate under conditions of smaller processing bandwidth and lower processing clock, thereby operating in a state with lower power consumption.

[0059] The core concept of BWP is to define an access bandwidth that is smaller than both the cell system bandwidth and the terminal bandwidth capability. All terminal transmission and reception operations can be performed within this smaller bandwidth, thereby achieving more flexible, more efficient, and lower power consumption terminal operation in the 5G large-bandwidth system. The maximum single-carrier system bandwidth of LTE is 20MHz, and the single-carrier bandwidth capability of the terminal is also 20MHz, so there is no situation where the terminal capability is less than the cell system bandwidth. In the 5G NR system, the maximum carrier bandwidth will be greatly increased (such as 400MHz), but the improvement in terminal bandwidth capability will obviously not keep up with the network side (such as 100MHz). In addition, the terminal does not need to always operate at the maximum bandwidth capability. In order to save power and more efficient frequency domain operation, it can operate in a smaller bandwidth, that is, BWP.

[0060] The NR system supports the concepts of cell group-cell and carrier-BWP in a hierarchical manner. The relationship between cell carrier bandwidth, single-carrier terminal bandwidth capability, and BWP is shown in Figure 3.

[0061] The above briefly explains the relevant technologies / terms involved in this application, which will not be repeated in the following embodiments.

[0062] When the number of carriers that need to be aggregated increases, the concept of "cells" is currently used to support different carriers, which means that the number of cells that need to be aggregated increases. In current system designs, supporting each cell requires the consumption of relatively independent resources. For example, different cells require independent definition of synchronization signal blocks (SSBs) and reference signals; different cells occupy different hybrid automatic repeat request (HARQ) buffers; and different cells require independent control channel resources. In other words, each cell needs to be configured with independent parameters, and different parameters correspond to relatively independent resource consumption.

[0063] Therefore, the concept of cells can be further expanded from only covering in-band continuous frequency resources to covering in-band non-contiguous and cross-band frequency resources to avoid the linear increase in the number of cells with the aggregated frequency resources, thereby weakening or removing the concept of cell groups in the NR system. In other words, one cell can be used to aggregate multiple traditional carriers. However, from the perspective of terminal reporting capability (communication capability), the increase in the number of aggregated frequency resources will lead to a further increase in the overhead of terminal capability reporting signaling, and this increase is not linear.

[0064] Terminal capabilities can be discussed in the following two situations:

[0065] Case 1: The terminals use the aggregated frequency resources simultaneously.

[0066] Case 2: The terminals use the aggregated frequency resources in a time-sharing manner.

[0067] For situation 1, in the current signaling structure, a large number of terminal capabilities are reported for each frequency band / component carrier and each frequency band combination (BC) (per-band / CC-per-BC), and these capabilities consume a lot of signaling overhead. For situation 2, the design difficulty lies in ensuring that the frequency resources used by the terminal in time-sharing do not exceed the terminal's capabilities, while also ensuring that the terminal's maximum capabilities are fully reflected. In the current signaling structure, the relevant design is simplified, that is, it is assumed that the terminal can use a dual-transmission link (Tx Chain) frequency band or two single-transmission link frequency bands at the same time, and the reported per-band-per-BC capabilities do not change according to the matching frequency bands or the number of transmission links used.

[0068] Based on this assumption, in the current 5G system, when the terminal is configured with multiple frequency bands at the same time and the terminal can support different frequency band combinations composed of the multiple frequency bands in a time-sharing manner, the terminal can report a communication capability for each of the multiple frequency bands, without considering that the communication capability of the terminal on each frequency band may change with different frequency band combinations (matching) methods.

[0069] For example, the terminal can be configured with frequency band #1, frequency band #2 and frequency band #3 at the same time. Assuming that the terminal can support [frequency band #1, frequency band #2] (that is, the terminal can communicate on frequency band #1 and frequency band #2 at the same time) and [frequency band #1, frequency band #3] (that is, the terminal can communicate on frequency band #1 and frequency band #3 at the same time) in a time-sharing manner, but the terminal cannot communicate on frequency band #1, frequency band #2 and frequency band #3 at the same time. In this scenario, the terminal can report a communication capability for frequency band #1, frequency band #2 and frequency band #3 respectively, without considering the situation that the terminal's communication capability on frequency band #1 may change with the combination with frequency band #2 and frequency band #3.

[0070] This may cause the reported communication capability on a certain frequency band to exceed the capability range of the terminal when paired with a different frequency band, or fail to fully reflect the maximum capability of the terminal.

[0071] For example, when frequency band #1 and frequency band #2 are used together, the terminal's maximum communication capability on frequency band #1 is capability A. When frequency band #1 and frequency band #3 are used together, the terminal's maximum communication capability on frequency band 1 is capability B. Assume that capability A is greater than capability B. Therefore, if the terminal reports capability A for frequency band #1, then when frequency band #1 and frequency band #3 are used together, the communication capability on frequency band #1 will exceed the terminal's capability range. If the terminal reports capability B for frequency band #1, then when frequency band #1 and frequency band #2 are used together, the terminal's maximum capability cannot be fully reflected on frequency band #1.

[0072] In view of this, the present application provides an information transmission method, apparatus, device, chip, and storage medium. In this method, a terminal may send (report) communication capability information for a first frequency band combination to a network device. The communication capability information for the first frequency band combination may include: a first communication capability for different frequency bands in the first frequency band combination; and / or a second communication capability for different frequency bands in different frequency band subcombinations, the different frequency band subcombinations being included in the first frequency band combination; wherein the first communication capability of the terminal device on the frequency band is unrelated to the frequency band combination mode, and the second communication capability of the terminal device on the frequency band is related to the frequency band combination mode.

[0073] According to the method of the embodiment of the present application, the first communication capability of the terminal device on the frequency band is not related to the frequency band combination mode, which can be explained that the first communication capability of the terminal device on different frequency bands does not change with different frequency band combination modes. Therefore, the terminal device can report the first communication capability separately for different frequency bands in the first frequency band combination to save signaling overhead; the second communication capability of the terminal device on the frequency band is related to the frequency band combination mode, which can be explained that the second communication capability of the terminal device on different frequency bands can change due to different frequency band combination modes. Therefore, the terminal device can report the second communication capability for different frequency bands in different frequency band sub-combinations in the first frequency band combination to avoid the situation where the second communication capability on a certain frequency band exceeds the capability range of the terminal device as the frequency band combination (sub-combination) changes, and can enable the second communication capability reported by the terminal device to adapt to different frequency band sub-combinations to fully reflect the communication capability of the terminal device.

[0074] It should be understood that the “communication capability” mentioned in the embodiments of the present application may also be referred to as “capability” in some scenarios.

[0075] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0076] FIG4 is a flow chart of an information transmission method provided in an embodiment of the present application. As shown in FIG4 , the method may include the following steps:

[0077] S401, the terminal device sends the communication capability information of the terminal device for the first frequency band combination to the network device, where the communication capability information for the first frequency band combination includes: a first communication capability for different frequency bands in the first frequency band combination; and / or, a second communication capability for different frequency bands in different frequency band sub-combinations, which are included in the first frequency band combination; wherein the first communication capability of the terminal device on the frequency band is not related to the frequency band combination mode, and the second communication capability of the terminal device on the frequency band is related to the frequency band combination mode.

[0078] In this embodiment, the terminal device may send (report) the communication capability information of the terminal device for the first frequency band combination to the network device, and accordingly, the network device may receive the communication capability information for the first frequency band combination from the terminal device.

[0079] In some embodiments, the communication capability information for the first frequency band combination includes: first communication capabilities for different frequency bands in the first frequency band combination.

[0080] For example, assuming that the first frequency band combination includes N frequency bands, which are respectively recorded as frequency band #1, frequency band 2,..., frequency band N, then the communication capability information for the first frequency band combination may include: the first communication capability for frequency band #1 (the first communication capability of the terminal device on frequency band #1), the first communication capability for frequency band #2 (the first communication capability of the terminal device on frequency band #2),... the first communication capability for frequency band #3 (the first communication capability of the terminal device on frequency band #3).

[0081] In some embodiments, the first communication capability of a terminal device on a frequency band is independent of the frequency band combination, or in other words, the first communication capability of a terminal device on a frequency band does not change with different frequency band combinations. For example, assuming that when frequency band #1 is combined (paired) with frequency band #2, the value of the first communication capability of the terminal device on frequency band #1 is J. Then, when frequency band #1 is combined with another frequency band, for example, when frequency band #1 is combined with frequency band #3, the value of the first communication capability of the terminal device on frequency band #1 remains unchanged, namely, J.

[0082] Since the first communication capability of the terminal device on the frequency band is not related to the frequency band combination method, the terminal device can report a first communication capability for different frequency bands in the first frequency band combination without considering the combination between the frequency bands, thereby reducing signaling overhead.

[0083] It should be understood that the first communication capability in this embodiment can be, for example, any communication capability that is unrelated to the frequency band combination mode, and this embodiment of the present application is not limited to this.

[0084] In some embodiments, the communication capability information for the first frequency band combination includes second communication capabilities for different frequency bands in different frequency band sub-combinations, the different frequency band sub-combinations being included in the first frequency band combination.

[0085] The different frequency band sub-combination is included in the first frequency band combination. It can also be understood that the different frequency band sub-combination is obtained by performing different combinations of frequency bands in the first frequency band combination.

[0086] For example, when the first frequency band combination includes frequency band #1, frequency band #2, and frequency band #3, frequency band #1 and frequency band #2 may be combined to obtain the frequency band sub-combination [frequency band #1, frequency band #2], and frequency band #1 and frequency band #3 may be combined to obtain the frequency band sub-combination [frequency band #1, frequency band #3].

[0087] In some embodiments, the second communication capability of a terminal device on a frequency band is related to the frequency band combination, or in other words, the second communication capability of a terminal device on a frequency band may change due to different frequency band combinations. For example, assuming that when frequency band #1 is combined (paired) with frequency band #2, the second communication capability of the terminal device on frequency band #1 is K. Then, when frequency band #1 is combined with another frequency band, for example, when frequency band #1 is combined with frequency band #3, the value of the second communication capability of the terminal device on frequency band #1 may change, such as to K'.

[0088] Since the second communication capability of the terminal device on the frequency band is related to the frequency band combination method, in order to avoid the situation where the second communication capability on a certain frequency band exceeds the capability range of the terminal device as the frequency band combination changes, and to fully reflect the maximum capability of the terminal device as much as possible, the terminal device can report the second communication capability for different frequency bands in different frequency band sub-combinations.

[0089] For example, assuming that different frequency band subcombinations obtained by performing different combinations of the frequency bands in the first frequency band combination include: [frequency band #1, frequency band #2] and [frequency band #1, frequency band #3], the terminal device can report a second communication capability for [frequency band #1, frequency band #2], and can report a second communication capability for [frequency band #1, frequency band #3]. As a possible implementation method, when the terminal device reports the second communication capability for [frequency band #1, frequency band #2], it can report it according to the maximum second communication capability of the terminal device when communicating on [frequency band #1, frequency band #2]. When reporting the second communication capability for [frequency band #1, frequency band #2], it can also report it according to the maximum second communication capability of the terminal device when communicating on [frequency band #1, frequency band #3]. It can also ensure that in each frequency band subcombination, the second communication capability on each frequency band does not exceed the capability range of the terminal device.

[0090] It should be understood that the second communication capability in this embodiment can be, for example, any communication capability related to the frequency band combination mode, and this embodiment of the present application is not limited to this.

[0091] In some embodiments, the communication capability information for the first frequency band combination may include: first communication capabilities for different frequency bands in the first frequency band combination, and second communication capabilities for different frequency bands in different frequency band subcombinations included in the first frequency band combination.

[0092] In some embodiments, the second communication capabilities for different frequency bands in different frequency band subcombinations may include: one or more combinations of the second communication capabilities of the terminal device on each frequency band in the first frequency band subcombination; the first frequency band subcombination is one of the different frequency band subcombinations included in the first frequency band combination.

[0093] That is to say, for a certain frequency band subcombination (such as the first frequency band subcombination) among the above-mentioned different frequency band subcombinations, the terminal device can carry in the reported communication capability information: one or more combinations of the second communication capabilities of the terminal device on each frequency band in the frequency band subcombination.

[0094] For example, assuming that the first frequency band sub-combination includes frequency band #1 and frequency band #2, then for the first frequency band sub-combination, the terminal device may carry in the reported communication capability information: one or more combinations of the terminal device's second communication capabilities on frequency band #1 and frequency band #2.

[0095] In one example, the terminal device may carry in the reported communication capability information: a combination of the second communication capability on frequency band #1 and frequency band #2, for example:

[0096] [The second communication capability K1 of the terminal device on frequency band #1, the second communication capability K2 of the terminal device on frequency band #2].

[0097] In another example, the terminal device may carry in the reported communication capability information: multiple (taking 2 as an example) combinations of the second communication capabilities on frequency band #1 and frequency band #2, for example:

[0098] [second communication capability K1 of the terminal device on frequency band #1, second communication capability K2 of the terminal device on frequency band #2];

[0099] [The second communication capability K3 of the terminal device on frequency band #1, the second communication capability K4 of the terminal device on frequency band #2].

[0100] In some embodiments, the first frequency band subcombination may be, for example, any frequency band subcombination among different frequency band subcombinations included in the first frequency band combination. That is, for any frequency band subcombination among the different frequency band subcombinations, the terminal device may report one or more combinations of the second communication capabilities on each frequency band in the frequency band subcombination.

[0101] In some embodiments, the second communication capabilities for different frequency bands in different frequency band subcombinations may include: the sum of the second communication capabilities of the terminal device on each frequency band in the first frequency band subcombination; the first frequency band subcombination is one of the different frequency band subcombinations included in the first frequency band combination.

[0102] That is to say, for a certain frequency band subcombination (such as the first frequency band subcombination) among the above-mentioned different frequency band subcombinations, the terminal device may carry in the reported communication capability information: the sum of the second communication capabilities on each frequency band in the frequency band subcombination.

[0103] For example, assuming that the first frequency band subcombination includes frequency band #1 and frequency band #2, then for the first frequency band subcombination, the terminal device may carry in the reported communication capability information: the sum of the second communication capabilities of the terminal device on frequency band #1 and frequency band #2.

[0104] In some embodiments, the sum of the second communication capabilities of the terminal device on frequency band #1 and frequency band #2 can be expressed as: the second communication capability of the terminal device on frequency band #1 + the second communication capability of the terminal device on frequency band #2.

[0105] In some embodiments, the sum of the second communication capabilities of the terminal device on each frequency band in the first frequency band subcombination is: a weighted sum of the second communication capabilities of the terminal device on each frequency band in the first frequency band subcombination.

[0106] For example, the sum of the second communication capabilities of a terminal device on frequency band #1 and frequency band #2 can be expressed as: the second communication capability of the terminal device on frequency band #1 × w1 + the second communication capability of the terminal device on frequency band #2 × w2, where w1 is the weight factor corresponding to frequency band #1, and w2 is the weight factor corresponding to frequency band #2.

[0107] In some embodiments, the weighting factors corresponding to different frequency bands may be related to parameter sets (numerologies) corresponding to the different frequency bands. The parameter sets may include, but are not limited to, subcarrier spacing and / or symbol length. In this way, the sum of the second communication capabilities reported by the terminal device can be adapted to different parameter sets.

[0108] According to the above technical solution, the terminal device may not need to report one or more combinations of the second communication capabilities of the terminal device on frequency band #1 and frequency band #2, thereby reducing signaling overhead.

[0109] In some embodiments, the first frequency band subcombination may be, for example, any frequency band subcombination among different frequency band subcombinations included in the first frequency band combination. In other words, for any frequency band subcombination among the different frequency band subcombinations, the terminal device may report the sum of the second communication capabilities of each frequency band in the frequency band subcombination.

[0110] In some embodiments, when the communication capability information for the first frequency band combination includes the second communication capability for different frequency bands in different frequency band sub-combinations, if the second communication capability for different frequency band sub-combinations includes the sum of the second communication capabilities of the terminal device on each frequency band in the first frequency band sub-combination, then the communication capability information may also include: the range of the second communication capability of the terminal device on each frequency band in the first frequency band sub-combination.

[0111] In which, the range of the second communication capability of the terminal device on each frequency band in the first frequency band sub-combination can be represented by a maximum value and a minimum value, for example, that is, the terminal device can carry the maximum value and minimum value of the second communication capability of the terminal device on each frequency band in the first frequency band sub-combination in the communication capability information.

[0112] For example, assuming that the first frequency band subcombination includes frequency band #1 and frequency band #2, in this case, if the communication capability information reported by the terminal device carries the sum of the second communication capabilities of the terminal device on frequency band #1 and frequency band #2, the terminal device may also carry in the communication capability information: the range of the second communication capability of the terminal device on frequency band #1 (such as the maximum value and the minimum value), and the range of the second communication capability of the terminal device on frequency band #2. In some embodiments, if the range of the second communication capability of the terminal device on frequency band #1 is the same as the range of the second communication capability of the terminal device on frequency band #2, the terminal device may uniformly report a range of the second communication capability for frequency band #1 and frequency band #2, without having to report a range of the second communication capability for each of frequency band #1 and frequency band #2, so as to further save signaling overhead.

[0113] In some embodiments, the terminal device cannot communicate on all frequency bands included in the first frequency band combination at the same time.

[0114] In some embodiments, the terminal device is capable of communicating simultaneously on multiple frequency bands included in the first frequency band subcombination, where the first frequency band subcombination is one of the different frequency band subcombinations included in the first frequency band combination.

[0115] That is, the terminal device does not support communication on all frequency bands included in the first frequency band combination at the same time, but can communicate on multiple frequency bands included in the frequency band sub-combination (such as the first frequency band sub-combination).

[0116] In some embodiments, the first frequency band subcombination may be any frequency band subcombination among different frequency band subcombinations included in the first frequency band combination, that is, the terminal device can communicate simultaneously on multiple frequency bands included in any frequency band subcombination among the different frequency band subcombinations.

[0117] For example, assuming the first frequency band combination includes the following frequency band subcombinations: [Band #1, Band #2] and [Band #1, Band #3], this means that the terminal device can communicate simultaneously on Band #1 and Band #2, and can also communicate simultaneously on Band #1 and Band #3. In other words, the terminal device can support [Band #1, Band #2] and [Band #1, Band #3] in a time-sharing manner.

[0118] According to the above technical solution, the communication capability information reported by the terminal device may carry not only the sum of the second communication capabilities of the terminal device on each frequency band in the first frequency band sub-combination, but also the range of the second communication capabilities of the terminal device on each frequency band in the first frequency band sub-combination. In this way, after receiving the communication capability information, the network device may configure the parameters of the terminal device when communicating on each frequency band in the first frequency band sub-combination based on the sum of the second communication capabilities of the terminal device on each frequency band in the first frequency band sub-combination and the range of the second communication capabilities of the terminal device on each frequency band in the first frequency band sub-combination, so as to ensure that the values ​​of the parameters of the terminal device on each frequency band fall within the capability range corresponding to each frequency band.

[0119] In some embodiments, before the terminal device sends the communication capability information of the terminal device for the first frequency band combination to the network device, or before the network device receives the communication capability information for the first frequency band combination from the terminal device, the method may further include: the network device sends indication information to the terminal device, and accordingly, the terminal device can receive indication information from the network device, and the indication information can be used to instruct the terminal device to report the communication capability information of the terminal device for at least one first frequency band; wherein the at least one first frequency band includes the frequency bands in the first frequency band combination.

[0120] That is to say, the network device may instruct the terminal device to report the communication capability information of the terminal device for at least one first frequency band. After the terminal device receives the indication information, if the at least one first frequency band includes a frequency band in the first frequency band combination, the terminal device may respond to the indication information and send (report) the communication capability information of the terminal device for the first frequency band combination to the network device.

[0121] To facilitate understanding of the embodiments of the present application, possible implementation solutions applicable to the method shown in FIG4 are introduced below with reference to examples.

[0122] For example, assume that the terminal device is configured with frequency band #1, frequency band #2 and frequency band #3 at the same time, and the terminal device can support [frequency band #1, frequency band #2] (that is, the terminal device can communicate on frequency band #1 and frequency band #2 at the same time) and [frequency band #1, frequency band #3] (that is, the terminal device can communicate on frequency band #1 and frequency band #3 at the same time) in a time-sharing manner, but the terminal device cannot communicate on frequency band #1, frequency band #2 and frequency band #3 at the same time. In this scenario, for the combination of frequency band #1, frequency band #2 and frequency band #3 (an example of the first frequency band combination), the terminal device can use the following method 1 and / or method 2 to report the communication capability.

[0123] Method 1: For the communication capability that does not change with the mutual matching between frequency band #1, frequency band #2 and frequency band #3 (ie, the first communication capability), the terminal device can report a communication capability for each of frequency band #1, frequency band #2 and frequency band #3.

[0124] For example, for the power amplifier (PA) capability supported by the terminal device on frequency band #1, frequency band #2 and frequency band #3, since this capability is not related to the frequency band combination method, that is, this capability does not change with the mutual matching between frequency band #1, frequency band #2 and frequency band #3, the terminal device can report a PA capability for each frequency band #1, frequency band #2 and frequency band #3.

[0125] Method 2: For the communication capability that changes with the mutual matching between frequency band #1, frequency band #2 and frequency band #3 (ie, the second communication capability), the terminal device can report a communication capability for each time-sharing supported frequency band sub-combination.

[0126] For example, when the terminal device can support [Band #1, Band #2] and [Band #1, Band #3] in a time-sharing manner, the terminal device can report a communication capability for [Band #1, Band #2] and can report a communication capability for [Band #1, Band #3].

[0127] As mentioned above, in the scenario where terminal devices simultaneously use aggregated frequency resources (corresponding to the aforementioned situation 1), in the current signaling structure, a large number of terminal capabilities are reported for each frequency band / component carrier and each frequency band combination (Band Combination, BC) (per-band / CC-per-BC), and these capabilities consume a lot of signaling overhead.

[0128] For example, assuming that the terminal device can support [Band #1, Band #2] at the same time, that is, the terminal can communicate on Band #1 and Band #2 at the same time, then the terminal device needs to report the communication capabilities for Band #1 and Band #2 separately, and can report multiple capability combinations. For example, the following capability combinations can be reported:

[0129] [communication capability of the terminal device on frequency band #1 is A1, and communication capability of the terminal device on frequency band #2 is A2];

[0130] [The communication capability of the terminal device in frequency band #1 is B1, and the communication capability of the terminal device in frequency band #2 is B2].

[0131] The above capability combinations indicate that a terminal device's communication capability A1 on frequency band #1 can be paired with its communication capability A2 on frequency band #2; and a terminal device's communication capability B1 on frequency band #1 can be paired with its communication capability B2 on frequency band #2. This indicates that this reporting method requires reporting capabilities for each frequency band and each capability combination (pairing), resulting in high signaling overhead.

[0132] In view of this, the present application also provides an information transmission method. In this method, a terminal device may send (report) communication capability information for a first frequency band combination to a network device. The communication capability information may include: the sum of the first communication capability of the terminal device on multiple frequency bands included in the first frequency band combination; and / or, the common value of the second communication capability of the terminal device on multiple frequency bands included in the first frequency band combination. In this way, the terminal device may not need to report the first communication capability and / or the second communication capability separately for each frequency band in the first frequency band combination, thereby reducing signaling overhead.

[0133] FIG5 is a flow chart of an information transmission method provided in an embodiment of the present application. As shown in FIG5 , the method may include the following steps:

[0134] S501, the terminal device sends the communication capability information of the terminal device for the first frequency band combination to the network device, and the communication capability information includes: the sum of the first communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination; and / or, the common value of the second communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination.

[0135] In this embodiment, the terminal device may send (report) the communication capability information of the terminal device for the first frequency band combination to the network device, and accordingly, the network device may receive the communication capability information for the first frequency band combination from the terminal device.

[0136] In some embodiments, the communication capability information may include: the sum of the first communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination.

[0137] As an implementation method, assuming that the first frequency band combination includes N frequency bands, which are respectively recorded as frequency band #1, frequency band 2,..., frequency band N, then the sum of the first communication capabilities of the terminal device on the N frequency bands included in the first frequency band combination can be expressed as: the first communication capability of the terminal device on frequency band #1 + the first communication capability of the terminal device on frequency band #2 +... + the first communication capability of the terminal device on frequency band #N.

[0138] As another implementation method, the sum of the first communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination is: the result of weighted summation of the first communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination. For example, assuming that the first frequency band combination includes N frequency bands, which are respectively recorded as frequency band #1, frequency band 2, ..., frequency band N, then the sum of the first communication capabilities of the terminal device on the N frequency bands included in the first frequency band combination can be expressed as: the first communication capability of the terminal device on frequency band #1 × w1 + the first communication capability of the terminal device on frequency band #2 × w2 + ... + the first communication capability of the terminal device on frequency band #N × w n Where w1 is the weight factor corresponding to frequency band #1, w2 is the weight factor corresponding to frequency band #2, and w n is the weight factor corresponding to frequency band #N.

[0139] In some embodiments, the weighting factors corresponding to different frequency bands may be related to parameter sets (numerologies) corresponding to the different frequency bands. The parameter sets may include, but are not limited to, subcarrier spacing and / or symbol length. In this way, the sum of the first communication capabilities reported by the terminal device can be adapted to different parameter sets.

[0140] According to the above technical solution, the terminal device may not need to report a first communication capability for each of frequency band #1, frequency band 2, ..., and frequency band N, thereby reducing signaling overhead.

[0141] As an example, assume that the first frequency band combination includes frequency band #1 and frequency band #2. In this case, the communication capability information reported by the terminal device may, for example, include: the sum of the first communication capabilities of the terminal device on frequency band #1 and frequency band #2 (for example, denoted as X).

[0142] In some embodiments, the first communication capability may have the following characteristics: the sum of the first communication capabilities of the terminal device on multiple different frequency bands, that is, the first communication capability of the terminal device when communicating simultaneously on the multiple different frequency bands. In other words, the first communication capability represents the communication capability that can be flexibly deployed on each frequency band and can be expressed as a sum (addition). For example, the first communication capability can be the channel bandwidth, the channel bandwidth supported by the terminal device on frequency band #1 + the channel bandwidth supported by the terminal device on frequency band #2, that is, the channel bandwidth supported by the terminal device when communicating simultaneously on frequency band #1 and frequency band #2.

[0143] It should be understood that the first communication capability in this embodiment can be, for example, any communication capability that meets the above characteristics, and this embodiment of the present application is not limited to this.

[0144] In some embodiments, if there are multiple communication capabilities that meet the above characteristics, the terminal device may carry the sum of the multiple communication capabilities in the communication capability information.

[0145] For example, if capability A (an example of the first communication capability) and capability B (another example of the first communication capability) both meet the above characteristics, then the terminal device may carry in the reported communication capability information: the sum of the A capabilities of the terminal device on multiple frequency bands included in the first frequency band combination, and the sum of the B capabilities of the terminal device on multiple frequency bands included in the first frequency band combination.

[0146] As an example, assuming that the first frequency band combination includes frequency band #1 and frequency band #2, in this case, the communication capability information reported by the terminal device may include:

[0147] The sum of the A-capabilities of the terminal device on frequency band #1 and frequency band #2 (e.g., denoted as X1);

[0148] The sum of the B-capabilities of the terminal device on frequency band #1 and frequency band #2 (for example, denoted as X2).

[0149] In some embodiments, the communication capability information may include: a common value of the second communication capability of the terminal device on multiple frequency bands included in the first frequency band combination.

[0150] That is, if the values ​​of the second communication capability of the terminal device on the N (N greater than or equal to 2) frequency bands included in the first frequency band combination are all the same, the terminal device can carry this value in the communication capability information for reporting. This value is also the common value of the second communication capability of the terminal device on the N frequency bands included in the first frequency band combination.

[0151] For example, assuming that the value of the second communication capability of the terminal device on frequency band #1 in the first frequency band combination is Y, and the value of the second communication capability on frequency band #2 in the first frequency band combination is also Y, the terminal device can carry the value of Y in the communication capability information, indicating that the values ​​of the second communication capability of the terminal device on frequency band #1 and frequency band #2 are both Y. In this way, the terminal device does not need to report the second communication capability of the terminal device on frequency band #1 and frequency band #2 separately, thereby reducing signaling overhead.

[0152] As an example, assume that the first frequency band combination includes frequency band #1 and frequency band #2. In this case, the communication capability information reported by the terminal device may, for example, include: the common value of the second communication capability of the terminal device on frequency band #1 and frequency band #2 (for example, denoted as Y).

[0153] In some embodiments, the second communication capability represents a communication capability that can be flexibly allocated on various frequency bands and can be expressed as a common value, such as the number of multiple-input multiple-output (MIMO) layers.

[0154] It should be understood that the second communication capability in this embodiment can be, for example, any communication capability that can be expressed by a common value, and this embodiment of the present application is not limited to this.

[0155] In some embodiments, if there are multiple communication capabilities that can be expressed with common values, the terminal device may carry the common values ​​of the multiple communication capabilities in the communication capability information.

[0156] For example, if both C capability (an example of the second communication capability) and D capability (another example of the second communication capability) can be expressed as common values, then the terminal device can carry in the reported communication capability information: the common value of the C capability of the terminal device on multiple frequency bands included in the first frequency band combination, and the common value of the D capability of the terminal device on multiple frequency bands included in the first frequency band combination.

[0157] As an example, assuming that the first frequency band combination includes frequency band #1 and frequency band #2, in this case, the communication capability information reported by the terminal device may include:

[0158] The common value of the terminal device's C capability on frequency band #1 and frequency band #2 (e.g., denoted as Y1);

[0159] The common value of the D capability of the terminal device on frequency band #1 and frequency band #2 (for example, denoted as Y2).

[0160] In some embodiments, the communication capability information may include: the sum of the first communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination, and the common value of the second communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination.

[0161] As an example, assuming that the first frequency band combination includes frequency band #1 and frequency band #2, in this case, the communication capability information reported by the terminal device may include:

[0162] The sum of the first communication capabilities of the terminal device on frequency band #1 and frequency band #2 (e.g., denoted as X);

[0163] A common value (e.g., denoted as Y) of the second communication capability of the terminal device on frequency band #1 and frequency band #2.

[0164] In some embodiments, the communication capability information further includes: one or more combinations of third communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination.

[0165] As an example, assume that the first frequency band combination includes frequency band #1 and frequency band #2, and the communication capability information includes a combination of the third communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination. In this case, the communication capability information reported by the terminal device may include, for example:

[0166] [The third communication capability P1 of the terminal device on the frequency band #1, the third communication capability P2 of the terminal device on the frequency band #2].

[0167] This combination indicates that the third communication capability P1 of the terminal device on frequency band #1 can be matched with the third communication capability P2 of the terminal device on frequency band #2.

[0168] As another example, assume that the first frequency band combination includes frequency band #1 and frequency band #2, and the communication capability information includes multiple (taking 2 as an example) combinations of the third communication capability of the terminal device on the multiple frequency bands included in the first frequency band combination. In this case, the communication capability information reported by the terminal device may include, for example:

[0169] [third communication capability P1 of the terminal device on frequency band #1, third communication capability P2 of the terminal device on frequency band #2];

[0170] [The third communication capability Q1 of the terminal device on the frequency band #1, the third communication capability Q2 of the terminal device on the frequency band #2].

[0171] The above two combinations respectively indicate that the third communication capability P1 of the terminal device on frequency band #1 can be matched with the third communication capability P2 of the terminal device on frequency band #2; the third communication capability Q1 of the terminal device on frequency band #1 can be matched with the communication capability Q2 of the terminal device on frequency band #2.

[0172] In some embodiments, the third communication capability information may be, for example, a communication capability that cannot be expressed as a common value and / or a sum. It is understandable that due to the diversity of the communication capabilities of the terminal devices, there may be certain communication capabilities that cannot be expressed as a common value and / or a sum. For communication capabilities that cannot be expressed as a sum, it is impossible to use the above-mentioned reporting method similar to the first communication capability for capability reporting. For communication capabilities that cannot be expressed as a common value, it is impossible to use the above-mentioned reporting method similar to the second communication capability for capability reporting. In this case, for the multiple frequency bands included in the first frequency band combination, the terminal device may report one or more combinations of the third communication capabilities of the terminal device on the multiple frequency bands.

[0173] In some embodiments, when the communication capability information includes the sum of the first communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination, the sum of the first communication capabilities may include: multiple values ​​of the sum of the first communication capabilities.

[0174] As an example, assuming that the first frequency band combination includes frequency band #1 and frequency band #2, taking the sum of the first communication capabilities including two values ​​of the sum of the first communication capabilities as an example, the communication capability information reported by the terminal device may include:

[0175] A first value (for example, denoted as X) of the sum of the first communication capabilities of the terminal device on frequency band #1 and frequency band #2.

[0176] A second value (for example, denoted as X') of the sum of the first communication capabilities of the terminal device on frequency band #1 and frequency band #2.

[0177] The above-mentioned reported communication capability information may indicate that, in one possible case, the sum of the first communication capabilities of the terminal device on frequency band #1 and frequency band #2 may be X; in another possible case, the sum of the first communication capabilities of the terminal device on frequency band #1 and frequency band #2 may be X'.

[0178] In some embodiments, when the communication capability information includes one or more combinations of the third communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination, each combination of the third communication capabilities can correspond to one of multiple values ​​(such as X and X') of the sum of the first communication capabilities.

[0179] As an example, assume that the terminal device carries two combinations of the third communication capability in the reported communication capability information, namely:

[0180] Combination 1: [the third communication capability P1 of the terminal device on frequency band #1, the third communication capability P2 of the terminal device on frequency band #2];

[0181] Combination 2: [the third communication capability Q1 of the terminal device on frequency band #1, the third communication capability Q2 of the terminal device on frequency band #2].

[0182] In this case, combination 1 may correspond to X, for example, and combination 2 may correspond to X', for example; or combination 1 may correspond to X', for example, and combination 2 may correspond to X, for example.

[0183] Assuming that combination 1 corresponds to X and combination 2 corresponds to X', the content of the communication capability information reported by the terminal device may include the following two items:

[0184] 1) [the third communication capability P1 of the terminal device on frequency band #1, the third communication capability P2 of the terminal device on frequency band #2] and X.

[0185] This item indicates: Given the combination of [the terminal device's third communication capability P1 on frequency band #1, and the terminal device's third communication capability P2 on frequency band #2], the sum of the terminal device's first communication capabilities on frequency band #1 and frequency band #2 is X. Taking the channel bandwidth as an example, this item indicates: Given the combination of [the terminal device's third communication capability P1 on frequency band #1, and the terminal device's third communication capability P2 on frequency band #2], the sum of the bandwidth supported by the terminal device on frequency band #1 and frequency band #2 is X.

[0186] 2) [the third communication capability Q1 of the terminal device on frequency band #1, the third communication capability Q2 of the terminal device on frequency band #2] and X'.

[0187] This item indicates that, given the combination of [the terminal device's third communication capability Q1 on frequency band #1, and the terminal device's third communication capability Q2 on frequency band #2], the sum of the terminal device's first communication capabilities on frequency band #1 and frequency band #2 is X'. Taking the channel bandwidth as an example, the first communication capability indicates that, given the combination of [the terminal device's third communication capability Q1 on frequency band #1, and the terminal device's third communication capability Q2 on frequency band #2], the sum of the bandwidth supported by the terminal device on frequency band #1 and frequency band #2 is X'.

[0188] In some embodiments, when the communication capability information includes a common value of the second communication capability of the terminal device on multiple frequency bands included in the first frequency band combination, the common value of the second communication capability may include: multiple values ​​of the common value of the second communication capability.

[0189] As an example, assuming that the first frequency band combination includes frequency band #1 and frequency band #2, and taking the common value of the second communication capability including two values ​​of the common value of the second communication capability as an example, the communication capability information reported by the terminal device may include:

[0190] A first value (for example, denoted as Y) of the common value of the second communication capability of the terminal device on frequency band #1 and frequency band #2.

[0191] A second value (for example, denoted as Y') of the common value of the second communication capability of the terminal device on frequency band #1 and frequency band #2.

[0192] The above-mentioned reported communication capability information may indicate that, in one possible case, the common value of the second communication capability of the terminal device on frequency band #1 and frequency band #2 may be Y; in another possible case, the common value of the second communication capability of the terminal device on frequency band #1 and frequency band #2 may be Y'.

[0193] In some embodiments, when the communication capability information includes one or more combinations of the third communication capability of the terminal device on multiple frequency bands included in the first frequency band combination, each combination of the third communication capability can correspond to one of multiple values ​​(such as Y and Y') of the common value of the second communication capability.

[0194] As an example, assume that the terminal device carries two combinations of the third communication capability in the reported communication capability information, namely:

[0195] Combination 1: [the third communication capability P1 of the terminal device on frequency band #1, the third communication capability P2 of the terminal device on frequency band #2];

[0196] Combination 2: [the third communication capability Q1 of the terminal device on frequency band #1, the third communication capability Q2 of the terminal device on frequency band #2].

[0197] In this case, combination 1 may correspond to Y, for example, and combination 2 may correspond to Y', for example; or, combination 1 may correspond to Y', for example, and combination 2 may correspond to Y, for example.

[0198] Assuming that combination 1 corresponds to Y and combination 2 corresponds to Y', the content of the communication capability information reported by the terminal device may include the following two items:

[0199] 1) [the third communication capability P1 of the terminal device on frequency band #1, the third communication capability P2 of the terminal device on frequency band #2] and Y.

[0200] This item indicates that, given the combination of [terminal device's third communication capability P1 on frequency band #1, terminal device's third communication capability P2 on frequency band #2], the common value of the terminal device's second communication capability on frequency band #1 and frequency band #2 is Y. Taking the second communication capability as the number of MIMO layers as an example, this item indicates that, given the combination of [terminal device's third communication capability P1 on frequency band #1, terminal device's third communication capability P2 on frequency band #2], the number of MIMO layers that the terminal device can support on both frequency band #1 and frequency band #2 is Y.

[0201] 2) [the third communication capability Q1 of the terminal device on frequency band #1, the third communication capability Q2 of the terminal device on frequency band #2] and Y'.

[0202] This item indicates that, given the combination of [terminal device's third communication capability Q1 on frequency band #1, terminal device's third communication capability Q2 on frequency band #2], the common value of the terminal device's second communication capability on frequency band #1 and frequency band #2 is Y'. Taking the second communication capability as the number of MIMO layers as an example, this item indicates that, given the combination of [terminal device's third communication capability Q1 on frequency band #1, terminal device's third communication capability Q2 on frequency band #2], the number of MIMO layers that the terminal device can support on both frequency band #1 and frequency band #2 is Y'.

[0203] In some embodiments, the communication capability information includes: the sum of the first communication capabilities of the terminal device across multiple frequency bands included in the first frequency band combination, and the common value of the second communication capabilities of the terminal device across multiple frequency bands included in the first frequency band combination. In this case, the sum of the first communication capabilities may include: multiple values ​​of the sum of the first communication capabilities; and the common value of the second communication capabilities may include: multiple values ​​of the common value of the second communication capabilities. The multiple values ​​of the sum of the first communication capabilities and the multiple values ​​of the common value of the second communication capabilities may have multiple combinations of values.

[0204] For example, assuming that the sum of the first communication capabilities includes two values ​​of the sum of the first communication capabilities (X and X' respectively), and the common value of the second communication capability includes two values ​​of the common value of the second communication capability (Y and Y' respectively), then there may be multiple value combinations between X, X' and Y, Y'.

[0205] For example, X, X' and Y, Y' can have multiple value combinations among the following value combinations:

[0206] Value combination 1: [XY], that is, X and Y can be used as a value combination, indicating that X can be used with Y;

[0207] Value combination 2: [X' Y'], that is, X' and Y' can be used as a value combination, indicating that X' can be used with Y';

[0208] Value combination 3: [X' Y], that is, X' and Y can be used as a value combination, indicating that X' can be used with Y;

[0209] Value combination 4: [X Y'], that is, X and Y' can be used as a value combination, indicating that X can be used with Y'.

[0210] In some embodiments, when the communication capability information includes one or more combinations of the third communication capability of the terminal device on multiple frequency bands included in the first frequency band combination, each combination of the third communication capability corresponds to at least one (or more) value combination of the above-mentioned multiple value combinations (multiple value combinations consisting of multiple values ​​of the sum of the first communication capability and multiple values ​​of the common value of the second communication capability).

[0211] In one possible scenario, each combination of the third communication capability may correspond to one value combination among the multiple value combinations.

[0212] As an example, assume that the terminal device carries two combinations of the third communication capability in the reported communication capability information, namely:

[0213] Combination 1: [the third communication capability P1 of the terminal device on frequency band #1, the third communication capability P2 of the terminal device on frequency band #2];

[0214] Combination 2: [the third communication capability Q1 of the terminal device on frequency band #1, the third communication capability Q2 of the terminal device on frequency band #2].

[0215] In this case, combination 1 and combination 2 may respectively correspond to one value combination among the multiple value combinations.

[0216] Assuming that combination 1 corresponds to [XY] and combination 2 corresponds to [X' Y'], the content of the communication capability information reported by the terminal device may include the following two items:

[0217] 1) [third communication capability P1 of the terminal device on frequency band #1, third communication capability P2 of the terminal device on frequency band #2], and [XY].

[0218] This item indicates: Under the combination of [the terminal device's third communication capability P1 on frequency band #1, and the terminal device's third communication capability P2 on frequency band #2], the sum of the terminal device's first communication capabilities on frequency band #1 and frequency band #2 is X, and the common value of the terminal device's second communication capabilities on frequency band #1 and frequency band #2 is Y. Taking the first communication capability as the channel bandwidth and the second communication capability as the number of MIMO layers as an example, this item indicates: Under the combination of [the terminal device's third communication capability P1 on frequency band #1, and the terminal device's third communication capability P2 on frequency band #2], the sum of the bandwidths supported by the terminal device on frequency band #1 and frequency band #2 is X, and the number of MIMO layers supported by the terminal device on frequency band #1 and frequency band #2 is Y.

[0219] 2) [third communication capability Q1 of the terminal device on frequency band #1, third communication capability Q2 of the terminal device on frequency band #2], and [X' Y'].

[0220] This item indicates that, given the combination of [the terminal device's third communication capability Q1 on frequency band #1, and the terminal device's third communication capability Q2 on frequency band #2], the sum of the terminal device's first communication capabilities on frequency band #1 and frequency band #2 is X', and the common value of the terminal device's second communication capabilities on frequency band #1 and frequency band #2 is Y'. Taking the first communication capability as the channel bandwidth and the second communication capability as the number of MIMO layers as an example, this item indicates that, given the combination of [the terminal device's third communication capability Q1 on frequency band #1, and the terminal device's third communication capability Q2 on frequency band #2], the sum of the bandwidths supported by the terminal device on frequency band #1 and frequency band #2 is X', and the number of MIMO layers supported by the terminal device on both frequency band #1 and frequency band #2 is Y'.

[0221] In another possible situation, each combination of the third communication capability may correspond to two or more value combinations among the foregoing multiple value combinations.

[0222] As an example, assume that the terminal device carries two combinations of the third communication capability in the reported communication capability information, namely:

[0223] Combination 1: [the third communication capability P1 of the terminal device on frequency band #1, the third communication capability P2 of the terminal device on frequency band #2];

[0224] Combination 2: [the third communication capability Q1 of the terminal device on frequency band #1, the third communication capability Q2 of the terminal device on frequency band #2].

[0225] In this case, combination 1 may correspond to two or more value combinations among the aforementioned multiple value combinations, and combination 2 may also correspond to two or more value combinations among the aforementioned multiple value combinations.

[0226] Assuming that combination 1 corresponds to [XY] and [X' Y'], and combination 2 corresponds to [XY] and [X' Y], the content of the communication capability information reported by the terminal device may include the following two items:

[0227] 1) [third communication capability P1 of the terminal device on frequency band #1, third communication capability P2 of the terminal device on frequency band #2], and [XY], [X' Y'].

[0228] This item indicates that under the combination of [the third communication capability P1 of the terminal device on frequency band #1, the third communication capability P2 of the terminal device on frequency band #2], in some scenarios, the sum of the first communication capabilities of the terminal device on frequency band #1 and frequency band #2 is X, and the common value of the second communication capabilities of the terminal device on frequency band #1 and frequency band #2 is Y; in other scenarios, the sum of the first communication capabilities of the terminal device on frequency band #1 and frequency band #2 is X', and the common value of the second communication capabilities of the terminal device on frequency band #1 and frequency band #2 is Y'.

[0229] Taking the first communication capability as channel bandwidth and the second communication capability as the number of MIMO layers as an example, this item means: under the combination of [the third communication capability P1 of the terminal device on frequency band #1, the third communication capability P2 of the terminal device on frequency band #2], in some scenarios, the total bandwidth that the terminal device can support on frequency band #1 and frequency band #2 is X, and the number of MIMO layers that the terminal device can support on frequency band #1 and frequency band #2 is Y; in other scenarios, the total bandwidth that the terminal device can support on frequency band #1 and frequency band #2 is X', and the number of MIMO layers that the terminal device can support on frequency band #1 and frequency band #2 is Y'.

[0230] 2) [third communication capability Q1 of the terminal device on frequency band #1, third communication capability Q2 of the terminal device on frequency band #2], and [XY], [X' Y].

[0231] This item indicates that under the combination of [the third communication capability Q1 of the terminal device on frequency band #1, the third communication capability Q2 of the terminal device on frequency band #2], in some scenarios, the sum of the first communication capabilities of the terminal device on frequency band #1 and frequency band #2 is X, and the common value of the second communication capabilities of the terminal device on frequency band #1 and frequency band #2 is Y; in other scenarios, the sum of the first communication capabilities of the terminal device on frequency band #1 and frequency band #2 is X', and the common value of the second communication capabilities of the terminal device on frequency band #1 and frequency band #2 is Y.

[0232] Taking the first communication capability as channel bandwidth and the second communication capability as the number of MIMO layers as an example, this item means: under the combination of [the third communication capability Q1 of the terminal device on frequency band #1, the third communication capability Q2 of the terminal device on frequency band #2], in some scenarios, the total bandwidth that the terminal device can support on frequency band #1 and frequency band #2 is X, and the number of MIMO layers that the terminal device can support on frequency band #1 and frequency band #2 is Y; in other scenarios, the total bandwidth that the terminal device can support on frequency band #1 and frequency band #2 is X', and the number of MIMO layers that the terminal device can support on frequency band #1 and frequency band #2 is Y.

[0233] In some embodiments, when the communication capability information includes the sum of the first communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination, the communication capability information may also include: the range of the first communication capabilities of the terminal device on multiple frequency bands.

[0234] Among them, the range of the first communication capability of the terminal device on multiple frequency bands can be represented by the maximum and minimum values, for example, that is, the terminal device can carry the maximum and minimum values ​​of the first communication capability of the terminal device on multiple frequency bands in the communication capability information.

[0235] As an implementation method, the range of the first communication capability of the terminal device on multiple frequency bands may include the range of the first communication capability of the terminal device on each of the multiple frequency bands. For example, assuming that the first frequency band combination includes frequency band #1, frequency band #2, and frequency band #3, then, in addition to carrying the sum of the first communication capabilities of the terminal device on frequency band #1, frequency band #2, and frequency band #3, the communication capability information may also carry: the range of the first communication capability of the terminal device on frequency band #1 (such as the maximum value and the minimum value), the range of the first communication capability of the terminal device on frequency band #2, and the range of the first communication capability of the terminal device on frequency band #3.

[0236] As another implementation method, if the range of the first communication capability of the terminal device on some of the multiple frequency bands (such as two or more frequency bands) is the same, the terminal device can report a range of the first communication capability for the part of the frequency bands to save signaling overhead. For example, assuming that the first frequency band combination includes frequency band #1, frequency band #2 and frequency band #3, and the range of the first communication capability of the terminal device on frequency band #1 is the same as the range of the first communication capability on frequency band #2 (for example, recorded as the first range), assuming that the range of the first communication capability of the terminal device on frequency band #3 is different from the first range (the range of the first communication capability of the terminal device on frequency band #3 is, for example, recorded as the second range), then in this case, in addition to carrying the sum of the first communication capabilities of the terminal device on frequency band #1, frequency band #2 and frequency band #3, the communication capability information can also carry: a first range (for frequency band #1 and frequency band #2) and a second range.

[0237] According to the above technical solution, the communication capability information reported by the terminal device may carry not only the sum of the first communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination, but also the range of the first communication capabilities of the terminal device on the multiple frequency bands. In this way, after receiving the communication capability information, the network device may configure the parameters of the terminal device when communicating on the multiple frequency bands based on the sum of the first communication capabilities of the terminal device on multiple frequency bands included in the first frequency band combination and the range of the first communication capabilities of the terminal device on the multiple frequency bands, so as to ensure that the values ​​of the parameters of the terminal device on each frequency band fall within the range of the first communication capabilities corresponding to each frequency band. For example, for the frequency bands in the first frequency band combination, the network device may perform the following operations: min (the maximum value of the first communication capability of the terminal device on the frequency band, X), max (the minimum value of the first communication capability of the terminal device on the frequency band, X), thereby obtaining the parameter X for the terminal to communicate on the frequency band.

[0238] In some embodiments, when the communication capability information includes a common value of the second communication capability of the terminal device on multiple frequency bands included in the first frequency band combination, the communication capability information may also include: a range of the second communication capability of the terminal device on multiple frequency bands.

[0239] Among them, the range of the second communication capability of the terminal device on multiple frequency bands can be represented by maximum and minimum values, for example, that is, the terminal device can carry the maximum and minimum values ​​of the second communication capability of the terminal device on multiple frequency bands in the communication capability information.

[0240] As an implementation method, the range of the second communication capability of the terminal device on multiple frequency bands may include the range of the second communication capability of the terminal device on each of the multiple frequency bands. For example, assuming that the first frequency band combination includes frequency band #1, frequency band #2, and frequency band #3, then, in addition to carrying the common value of the second communication capability of the terminal device on frequency band #1, frequency band #2, and frequency band #3, the communication capability information may also carry: the range of the second communication capability of the terminal device on frequency band #1 (such as the maximum value and the minimum value), the range of the second communication capability of the terminal device on frequency band #2, and the range of the second communication capability of the terminal device on frequency band #3.

[0241] As another implementation method, if the range of the second communication capability of the terminal device on some of the multiple frequency bands (such as two or more frequency bands) is the same, the terminal device can report a range of the second communication capability for the part of the frequency bands to save signaling overhead. For example, assuming that the first frequency band combination includes frequency band #1, frequency band #2 and frequency band #3, and the range of the second communication capability of the terminal device on frequency band #1 is the same as the range of the second communication capability on frequency band #2 (for example, recorded as the third range), assuming that the range of the second communication capability of the terminal device on frequency band #3 is different from the third range (the range of the second communication capability of the terminal device on frequency band #3 is, for example, recorded as the fourth range), then in this case, in addition to carrying the common value of the second communication capability of the terminal device on frequency band #1, frequency band #2 and frequency band #3, the communication capability information can also carry: a third range (for frequency band #1 and frequency band #2) and a fourth range.

[0242] According to the above technical solution, the communication capability information reported by the terminal device may carry not only the common value of the second communication capability of the terminal device on multiple frequency bands included in the first frequency band combination, but also the range of the second communication capability of the terminal device on the multiple frequency bands. In this way, after receiving the communication capability information, the network device may configure the parameters of the terminal device when communicating on the multiple frequency bands based on the common value of the second communication capability of the terminal device on multiple frequency bands included in the first frequency band combination and the range of the second communication capability of the terminal device on the multiple frequency bands, so as to ensure that the value of the parameter of the terminal device on each frequency band falls within the range of the second communication capability corresponding to each frequency band. For example, for the frequency bands in the first frequency band combination, the network device may perform the following operations: min (the maximum value of the second communication capability of the terminal device on the frequency band, Y), max (the minimum value of the second communication capability of the terminal device on the frequency band, Y), thereby obtaining the parameter Y for the terminal to communicate on the frequency band.

[0243] In some embodiments, the terminal device can simultaneously communicate on multiple frequency bands included in the first frequency band combination. In other words, the method is applicable to scenarios where the terminal device simultaneously uses aggregated frequency resources (such as simultaneously using multiple frequency bands included in the first frequency band combination).

[0244] In some embodiments, before the terminal device sends the communication capability information of the terminal device for the first frequency band combination to the network device, or before the network device receives the communication capability information for the first frequency band combination from the terminal device, the method may further include: the network device sends indication information to the terminal device, and accordingly, the terminal device may receive the indication information from the network device.

[0245] Exemplarily, the indication information may be used to indicate one or more of the following a) to c) to the terminal device:

[0246] a) reporting communication capability information of a terminal device for at least one first frequency band, wherein the at least one first frequency band includes a frequency band in a first frequency band combination.

[0247] That is to say, the network device may instruct the terminal device to report the communication capability information of the terminal device for at least one first frequency band. After the terminal device receives the indication information, if the at least one first frequency band includes a frequency band in the first frequency band combination, the terminal device may respond to the indication information and send (report) the communication capability information of the terminal device for the first frequency band combination to the network device.

[0248] b) Carrying the sum of the first communication capabilities in the communication capability information of the terminal device.

[0249] That is, the network device may instruct the terminal device that when reporting the communication capability information, the first communication capability may be reported in a manner of reporting the sum of the first communication capabilities.

[0250] c) Carrying the public value of the second communication capability in the communication capability information of the terminal device.

[0251] That is, the network device may instruct the terminal device that, when reporting the communication capability information, the second communication capability may be reported in a manner of reporting the public value of the second communication capability.
