Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and more particularly, to a method and apparatus for combined reception of bandwidth parts, a method and apparatus for combined transmission of bandwidth parts, an electronic device, and a computer-readable storage medium. Background Art

[0002] In communication systems such as 5G, a BWP (Bandwidth Part) mechanism is introduced. Multiple BWPs can be configured on a subcarrier, and one of them can be activated for use by a terminal. At the same time, communication systems such as 5G can also aggregate multiple subcarriers together through carrier aggregation or dual connection to simultaneously use multiple subcarriers for information transmission. Among them, each subcarrier in the aggregated carrier can be called a component carrier CC. Generally, at least one BWP can be configured for each CC, and one of the BWPs configured for each component carrier CC can be activated. Thus, each combination of BWPs that may be activated in the terminal includes one BWP on each CC.

[0003] For each combination of BWPs that may be activated, the terminal also needs to determine relevant information corresponding to the BWP combination, such as the position of the DC subcarrier. In the related art, the terminal can enumerate all BWP combinations that can be formed by the configured BWPs, and then separately determine the relevant information corresponding to each BWP combination. However, due to the large number of types of BWP combinations, determining relevant information for all BWP combinations wastes the terminal's load. Summary of the Invention

[0004] In view of this, embodiments of the present disclosure propose a method and apparatus for combined reception of bandwidth parts, a method and apparatus for combined transmission of bandwidth parts, to solve the technical problems in the related art.

[0005] According to a first aspect of an embodiment of the present disclosure, a method for combined reception of bandwidth parts is proposed, which is applied to a terminal. The method includes:

[0007] According to a second aspect of an embodiment of the present disclosure, a method for combined transmission of bandwidth parts is proposed, which is applied to a base station. The method includes:

[0008] Send the combined information of bandwidth parts (BWPs) to a terminal. The combined information includes at least one BWP combination, and the combined information is used to instruct the terminal to determine the positions of direct current sub - carrier corresponding to the at least one BWP combination. Wherein, the type of BWP combinations in the combined information is less than the type of combinations that can be formed by all the BWPs configured by the base station for the terminal.

[0009] According to the third aspect of the embodiments of the present disclosure, a combined receiving device for bandwidth parts is provided, which is applied to a terminal. The device includes:

The combined information includes at least one BWP combination, and the combined information is used to instruct the terminal to determine the positions of direct current sub - carrier corresponding to the at least one BWP combination. Wherein, the type of BWP combinations in the combined information is less than the type of combinations that can be formed by all the BWPs configured by the base station for the terminal.

When the program is executed by a processor, the steps in the above - mentioned combined receiving method for bandwidth parts and / or combined transmitting method for bandwidth parts are implemented.

[0018] According to an embodiment of the present disclosure, the terminal can receive the BWP combination information sent by the base station. Thus, the terminal can determine the DC subcarriers corresponding to the BWP combination based on the BWP combination information, rather than enumerating the DC subcarrier positions of all the BWP combinations that can be formed, reducing the performance pressure on the terminal. Further, if the terminal needs to send the DC subcarrier position to the base station, the terminal can send less data to the base station, saving signaling overhead. Description of the Drawings

[0032] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0033] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the embodiments of the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the embodiments of the present disclosure detailed in the appended claims.

[0034] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the embodiments of the present disclosure. The singular forms "a" and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0035] It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present disclosure to describe various information, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the words "if" and "when" used herein may be interpreted as "when" or "when" or "in response to determining".

[0036] Embodiments of the present disclosure will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0037] With the development of mobile communication technology and chip processing capabilities, it provides hardware support for FFT (Fast Fourier Transform) and OFDM (Orthogonal Frequency Division Multiplexing) technologies, and has also become an important foundation for communication technologies such as 4G and 5G. OFDM is a technology based on orthogonal subcarriers. When a terminal or a base station transmits a signal, due to the phase noise of the local oscillator, a relatively large noise will be generated at the carrier frequency, which can be called carrier leakage, thus causing distortion of the signal on the subcarrier where the local oscillator is located. Usually, the subcarrier where the local oscillator is located can be called the DC subcarrier.

[0038] In a communication system, in order to avoid the influence of carrier leakage and improve the demodulation performance of the base station, the base station needs to know the position of the DC subcarrier of the terminal for compensation processing and the like.

[0039] In a 4G system, the system bandwidth of the terminal and the base station is the same. Therefore, the base station can directly determine the position of the DC subcarrier of the terminal according to the system bandwidth.

[0040] In communication systems such as 5G, multiple BWPs can be configured within a single carrier, making the bandwidth of the terminal no longer fixed but determined by the activated BWP. Thus, the position of the DC subcarrier in the terminal is also related to the activated BWP, that is, it changes with different activated BWPs.

[0041] In the related art, after the terminal determines the activated BWP, it can send the position of the DC subcarrier to the base station. However, the activation state of the BWP in the terminal changes frequently. If the terminal re-sends the position of the DC subcarrier to the base station every time the activation state of the BWP changes, it not only wastes communication resources but also increases the performance pressure on the terminal and the base station.

[0042] To avoid the problems in the above related technologies, the terminal can pre-transmit the direct current subcarrier positions corresponding to all possible activated BWPs to the base station. For example, it can transmit the mapping relationship between each BWP and the direct current subcarrier position to indicate the direct current subcarrier position when the BWP is activated. For example, the terminal can send it through the txDirectCurrentLocation message. In this method, after determining the BWP activated by the terminal, the base station can directly query this mapping relationship to determine the position of the direct current subcarrier in the terminal, without having to separately obtain the direct current subcarrier position from the terminal, which not only saves communication resources but also reduces the performance pressure on the terminal and the base station.

[0043] One or more local oscillators (abbreviated as LO) and power amplifiers (abbreviated as PA, Power Amplifier) can be configured in the terminal, and generally, the LO and PA are in one-to-one correspondence, and each LO corresponds to a direct current subcarrier. Generally, for each LO, the terminal can send the direct current subcarrier position corresponding to this LO through the above method.

[0044] In communication systems such as 5G, the terminal can configure carrier aggregation (CA, Carrier Aggregation), dual connectivity (DC, Dual-Connectivity), etc., to aggregate multiple subcarriers together to simultaneously use multiple subcarriers for information transmission. Among them, the subcarriers aggregated together can be called component carriers CC (Component Carrier).

[0045] When the terminal configures multiple CCs, a corresponding PA can be determined for each CC. Here, PA corresponding to CC means that the CC corresponding to this PA is transmitted through the PA. If the number of CCs is not greater than the number of PAs, each PA corresponds to at most one CC. For each PA, the terminal can determine the mapping relationship between each BWP and the direct current subcarrier position on the CC corresponding to this PA; if the number of CCs is greater than the number of PAs, there are PAs corresponding to multiple CCs. For ease of description, here the PA corresponding to multiple CCs is called the target PA, and the direct current subcarrier position corresponding to this target PA is related to the combination of activated BWPs among the multiple CCs corresponding to this target PA.

[0046] In this case, for each target PA, the terminal can determine: the types of BWP combinations that can be formed by all the BWPs configured in all the CCs on this target PA. According to the related technology of BWPs, an activated CC can be determined from at least one CC on each CC, that is, one BWP is activated for each CC. Based on this, in each BWP combination in this embodiment, it can include one BWP belonging to different CCs on this target PA. Figure 1Taking the CC corresponding to a target PA shown as an example, the target PA corresponds to CC1 and CC2. Among them, CC1 is configured with 4 BWPs, namely BWP11, BWP12, BWP13, and BWP14; CC2 is also configured with 4 BWPs, namely BWP21, BWP22, BWP23, and BWP24. For this target PA, the BWP combinations it can form consist of one BWP belonging to CC1 and one BWP belonging to CC2, that is, 16 BWP combinations can be formed.

[0047] However, a target PA can correspond to multiple CCs, and each CC can also be configured with multiple BWPs, such that the number of types of BWP combinations that can be formed by all the BWPs configured in all CCs on this target PA is numerous. For example Figure 1 As shown, the BWPs configured by the CC corresponding to this target PA can form 16 different BWP combinations. As the number of CCs increases, the number of formed BWP combinations will also increase sharply. If the terminal sends the DC subcarrier positions corresponding to all types of combinations it can form to the base station, the amount of information to be transmitted is large, wasting signaling overhead and causing relatively large performance pressure on both the terminal and the base station.

[0048] In view of this, embodiments of the present disclosure propose a BWP combination sending method and a BWP combination receiving method to solve the above technical problems.

[0049] Figure 2 FIG. is a schematic flowchart of a bandwidth part combination receiving method shown according to an embodiment of the present disclosure. The bandwidth part combination receiving method shown in this embodiment can be applicable to a terminal, and the terminal includes but is not limited to electronic devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal can communicate with a base station as a user equipment, and the base station includes but is not limited to 4G base stations, 5G base stations, and 6G base stations. In one embodiment, the base station can be the base station applicable to the bandwidth part combination sending method described in any subsequent embodiment.

[0050] As Figure 2 shown, the bandwidth part combination receiving method may include the following steps:

[0051] In step S201, receive the combination information of the bandwidth part BWP sent by the base station.

[0052] Among them, the combination information includes at least one BWP combination, and the combination information is used to instruct the terminal to determine the DC subcarrier positions corresponding to the at least one BWP combination; among them, the number of types of BWP combinations in the combination information is less than the number of types of combinations that can be formed by all the BWPs configured by the base station for the terminal.

[0053] In one embodiment, the base station may select at least one BWP combination according to a preset method. Then, the base station may form BWP combination information with the at least one BWP combination and send it to the terminal. Compared with the types of combinations that can be formed by all the BWPs configured by the terminal, the number of types of BWP combinations determined by the base station according to the preset method is smaller.

[0054] In one embodiment, the terminal may determine the DC subcarriers corresponding to the BWP combination. Wherein, the BWP combination may be all the BWP combinations in the BWP combination information, or may also be some BWP combinations, or the terminal may also determine one or more BWP combinations by itself, etc. As long as the type of the BWP combination is less than the type of combinations that can be formed by all the BWPs configured by the base station for the terminal, this embodiment does not make specific limitations.

[0055] According to the above embodiment, the terminal may receive the BWP combination information sent by the base station, so that the terminal may determine the DC subcarriers corresponding to the BWP combination based on the BWP combination information, rather than enumerating the DC subcarrier positions of the BWP combinations that can be formed by all the BWPs, reducing the performance pressure of the terminal; further, if the terminal needs to send the DC subcarrier position to the base station, the terminal may send less data to the base station, saving signaling overhead.

[0056] Figure 3 It is a schematic flowchart of another method for receiving a bandwidth part combination shown according to an embodiment of the present disclosure. As Figure 3 shown, the method may further include:

[0057] In step S301, determine the DC subcarrier positions corresponding to each BWP combination in the at least one BWP combination.

[0058] In one embodiment, after receiving the combination information of the BWPs, for each BWP combination in the combination information, the terminal respectively determines the DC subcarrier position of the terminal in the case that the activated BWP is the BWP in the BWP combination.

[0059] Taking Figure 1 as an example, for the BWP combination being BWP11 and BWP22, the terminal may determine the position of the DC subcarriers of the terminal in the case that BWP11 is activated in CC1 and BWP22 is activated in CC2 as the DC subcarriers shown in Figure 1 in.

[0060] It should be noted that here it is only taking Figure 1For a case where a BWP combination is illustrated, if the BWP combination includes other BWPs (for example, the BWP combination is BWP12 and BWP22), the terminal can also determine the position of the DC subcarrier in the terminal when the activated BWP is the BWP in the BWP combination.

[0061] In one embodiment, the position of the DC subcarrier can be expressed as a specific frequency, or can also be identified as the offset of the DC subcarrier position relative to a preset reference frequency, or can also be expressed in other ways, which is not limited in this embodiment.

[0062] In step S302, send the mapping relationship between each BWP combination and the DC subcarrier position to the base station.

[0063] In one embodiment, after the terminal determines the position of the DC subcarrier corresponding to each BWP combination in the BWP combination information, it can send the mapping relationship between each BWP combination and the DC subcarrier position to the base station.

[0064] In one example, the terminal can send the identifier of the BWP combination and the corresponding DC subcarrier position. For example, the terminal can send a table, where each table entry includes a BWP combination and the DC subcarrier position corresponding to the BWP combination; or, the terminal can send key-value pairs, and each key-value pair includes a BWP combination and the DC subcarrier position corresponding to the BWP combination, etc. Here, the table and key-value pairs are only illustrative. In actual applications, the terminal can also reflect the mapping relationship between the BWP combination and the DC subcarrier position in other forms.

[0065] In one example, the terminal can also determine the arrangement order of the DC subcarrier positions in a specified order, so as to determine the BWP combination corresponding to the DC subcarrier position through the order. For example, the terminal can determine the arrangement order of the DC subcarrier positions according to the arrangement order of each BWP in the BWP combination information; or, the BWP combination information can also include the priorities of each BWP, then the terminal can determine the arrangement order of the DC subcarrier positions according to the priority order, for example, using the order from high to low as the arrangement order of the DC subcarrier positions.

[0066] In one example, a default relative position can be set for the DC subcarrier in the terminal in advance. For example, it can be the frequency center point of the highest frequency and the lowest frequency in the frequency bands occupied by each BWP in the BWP combination, or it can also be a specified offset relative to the center point, such as an offset of 7.5 kHz relative to the center point, etc.

[0067] In one example, in response to the DC subcarrier position corresponding to the BWP combination being inconsistent with the default relative position, the terminal sends the description information of the DC subcarrier position corresponding to the BWP combination to the base station; or, in response to the DC subcarrier position corresponding to the BWP combination being consistent with the default relative position, the terminal sends preset information to the base station.

[0068] Among them, the description information can be used for the terminal to determine the DC subcarrier position. For example, it can be the frequency of the DC subcarrier, or the offset of the DC subcarrier position relative to the preset reference frequency, or the offset of the DC subcarrier position relative to the frequency center point, etc.

[0069] When the DC subcarrier position is consistent with the default relative position, in order to reduce the data volume, the terminal can no longer send the specific DC subcarrier position, but directly send a preset information to indicate to the base station that the DC subcarrier position is the pre-determined default relative position. Among them, the default relative position can be stipulated by the protocol, or can also be pre-negotiated and determined by the terminal and the base station, etc., which is not limited in this embodiment. Generally speaking, the data volume of the preset information is less than the description information of the DC subcarrier position. For example, the preset information can only occupy 1 bit. Thus, according to the method of this embodiment, the amount of information sent by the terminal to the base station can be further reduced, and the signaling overhead can be reduced.

[0070] It should be noted that the above method for the terminal to send the mapping relationship is only an exemplary illustration, and in practical applications, other methods may also be included, which are not limited in this embodiment.

[0071] In one embodiment, the base station receives the mapping relationship between each BWP combination and the DC subcarrier position in the at least one BWP combination sent by the terminal.

[0072] According to this mapping relationship, the base station can determine the DC subcarrier position corresponding to the BWP combination currently activated by the terminal. Thus, the base station does not need to query the DC subcarrier position corresponding to the BWP combination from the terminal after determining the activated BWP combination for the terminal, but directly determines the DC subcarrier position according to the previously received mapping relationship, reducing the signaling overhead and avoiding the delay caused by signaling interaction.

[0073] In one embodiment, the base station can send BWP combination information to all terminals.

[0074] In one embodiment, the base station may also not send BWP combination information to all terminals, but determine whether to send BWP combination information to the terminal according to the PA capability of the terminal. The following is combined with Figure 4 for description.

[0075] Figure 4It is a schematic flowchart of another method for combined reception of bandwidth parts shown according to an embodiment of the present disclosure. As Figure 4 shown, the method may further include:

[0076] Step S401: Report the power amplifier (PA) capability of the terminal to the base station. Wherein, the PA capability is used for the base station to determine to send the combined information to the terminal and to determine the combined information.

[0077] In one embodiment, the base station may receive the PA capability reported by the terminal and, based on the PA capability, determine to send the combined information to the terminal and to determine the combined information.

[0078] In one embodiment, the PA capability reported by the terminal may include the number of PAs of the terminal. It should be noted that since the local oscillator in the terminal corresponds one-to-one with the PA, the number of PAs is also the number of local oscillators. For the convenience of description, they will not be distinguished hereinafter.

[0079] In one embodiment, if the number of PAs is less than the number of component carriers (CCs) configured by the terminal, at least one of the at least one PA configured by the terminal includes at least one target PA corresponding to multiple CCs. For a PA corresponding to one CC, since a CC can be configured with at most 4 bandwidth parts (BWPs), and to simplify the solution, the base station may not send the BWP combination information to the terminal, but directly send the correspondence between all BWPs and the positions of the DC subcarriers by the base station, which will not cause excessive signaling overhead.

[0080] For the target PA corresponding to multiple CCs, the number of BWP combinations that can be formed by the BWPs in the multiple CCs corresponding to this PA is relatively large. If the correspondence between all BWPs and the positions of the DC subcarriers is sent, it will cause excessive signaling overhead. Based on this, in one embodiment, the base station may determine the number of PAs in the terminal according to the PA capability, and in response to the number of PAs being less than the number of component carriers (CCs) configured by the terminal, determine to send the combined information to the terminal.

[0081] In one embodiment, in response to the number of PAs being not less than the number of component carriers (CCs) configured by the terminal, the base station may determine not to send the combined information to the terminal. Thus, the base station can reduce the information to be sent and save communication resources.

[0082] In one embodiment, when the base station determines that it is necessary to send the BWP combination information to the terminal, it may determine the number of types of BWP combinations included in the combined information according to its own load. For the convenience of distinction, the number of types of BWP combinations in the BWP combination information may be denoted as the first number.

[0083] For example, the base station can determine that the first quantity is negatively correlated with the load of the base station. The higher the load of the base station, the fewer the types of BWP combinations included in the BWP combination information; the lower the load of the base station, the more the types of BWP combinations included in the BWP combination information. The specific method for the base station to determine the first quantity can be determined according to the actual situation, and this embodiment does not limit it here.

[0084] In one embodiment, when the base station determines that it needs to send BWP combination information to the terminal, it can determine the combination information according to the PA capability, that is, determine the specific types of BWP combinations in the combination information.

[0085] In one example, the PA capability may include the maximum channel bandwidth supported by the PA.

[0086] Based on this, in one embodiment, the base station can determine the maximum channel bandwidth supported by each PA in the terminal according to the PA capability. At the same time, the base station can determine the CC corresponding to each PA according to the bandwidths of multiple CCs configured by the terminal. For example, the terminal includes two PAs, and the terminal is configured with three CCs. The maximum bandwidth supported by one PA can only cover one of the CCs, while the maximum bandwidth supported by the other PA can cover the other two CCs. Then the base station can determine the corresponding relationship between the PA and the CC accordingly.

[0087] In one embodiment, if the number of PAs configured by the terminal and the number of CCs configured by the terminal are relatively large, for example, greater than 2, it is difficult for the base station to determine the corresponding relationship between the PA and the CC according to the maximum bandwidth supported by the PA and the bandwidth of each CC. To avoid errors, the terminal can report to the base station the CC corresponding to each PA in the terminal, for example, it can send the corresponding relationship between the PA and the CC. Thus, the base station can determine the CC corresponding to each PA respectively.

[0088] In one embodiment, if the number of PAs in the terminal is less than the number of CCs configured by the terminal, it can be determined that at least one target PA is included in the PAs set in the terminal, and the target PA corresponds to multiple component carriers CCs. Among the multiple CCs corresponding to the target PA, each CC corresponds to at least one BWP.

[0089] In one embodiment, the BWP combination information sent by the base station to the terminal can be the BWP combination information corresponding to the target PA. In each BWP combination in this BWP combination information, each BWP belongs to a different CC in the target PA. In one embodiment, the number of types of BWP combinations in this combination information is less than the number of all combinations that can be formed by the BWPs on the multiple CCs corresponding to the target PA.

[0090] Take Figure 1For example, if the target PA corresponds to CC1 and CC2, and CC1 and CC2 are respectively configured with 4 BWPs. For this target PA, among the BWP combinations that can be formed by the BWPs on the two CCs corresponding to this target PA, if the BWPs in each BWP combination belong to different CCs respectively, the number of types that can be formed is 16, which are respectively: BWP11 and BWP21; BWP11 and BWP22; BWP11 and BWP23; BWP11 and BWP24; BWP12 and BWP21; BWP12 and BWP22; BWP12 and BWP23; BWP12 and BWP24; BWP13 and BWP21; BWP13 and BWP22; BWP13 and BWP23; BWP13 and BWP24; BWP14 and BWP21; BWP14 and BWP22; BWP14 and BWP23; BWP14 and BWP24. According to the method described in this embodiment, the base station can send some types of the above 16 BWP combinations that can be formed to the terminal. For example, it can be 5 types, 10 types, etc., as long as it is less than 16 types, and this embodiment does not make a limitation.

[0091] In one embodiment, the terminal can receive the BWP combination information sent by the base station, such as 5 types, 10 types, etc. sent by the base station in the above example, and respectively determine the DC subcarriers corresponding to each BWP combination, and send the mapping relationship between each BWP combination and the DC subcarrier position to the base station. Compared with the related art where the terminal sends the DC subcarrier positions corresponding to all BWP combinations (such as the above 16 types) that can be formed by the BWPs on multiple CCs corresponding to the target PA to the base station, the method of this embodiment greatly reduces the data volume of the information sent by the terminal to the base station, which can not only save signaling overhead but also reduce the energy consumption of the terminal and the base station.

[0092] In one embodiment, when determining the BWP combination information, the base station can determine the BWP combination according to the BWPs on all CCs corresponding to the target PA. For example, the BWP combination can be determined such that the BWPs in each BWP combination correspond one by one to the multiple CCs corresponding to the target PA.

[0093] As Figure 5 shown, taking the target PA corresponding to three CCs (i.e., Figure 5 CC1, CC2, and CC3 in Figure 5 as an example), where CC1 includes 4 BWPs (i.e., Figure 5 BWP11, BWP12, BWP13, BWP14 in Figure 5 ), CC2 includes 4 BWPs (i.e.,

[0094] When determining the BWP combination information, the base station can select one BWP from the 4 BWPs on CC1, one BWP from the 4 BWPs on CC2, and one BWP from the 4 BWPs on CC3 respectively, to obtain 3 BWPs as a BWP combination. Using the same method, the base station can perform the above selection process multiple times as needed to continue obtaining other different types of BWP combinations. Thus, the BWPs in the BWP combination correspond one by one to the 3 CCs corresponding to the target PA.

[0095] In one embodiment, when determining the BWP combination information, the base station can also determine the BWP combination according to the BWPs on some of the CCs corresponding to the target PA. For example, the BWP combination can be determined such that the BWPs in each BWP combination correspond one by one to some of the CCs corresponding to the target PA. For example, if the target PA corresponds to 3 CCs, the BWP combination can be determined according to the BWPs on 2 of the 3 CCs.

[0096] In one example, the base station can determine the BWP combination according to the BWPs on the CC with the highest frequency band and the CC with the lowest frequency band among the multiple CCs corresponding to the target PA. For example, the BWP combination can be determined such that the BWPs in each BWP combination correspond to the CC with the highest frequency band and the CC with the lowest frequency band among the multiple CCs corresponding to the target PA.

[0097] Still taking Figure 5 as an example, among CC1, CC2, and CC3 corresponding to the target PA, the CC with the highest frequency band is CC3, and the CC with the lowest frequency band is CC1. Thus, when determining the BWP combination information, the base station can select one BWP from the 4 BWPs on CC1 and one BWP from the 4 BWPs on CC3 respectively, to obtain 2 BWPs as a BWP combination. Using the same method, the base station can perform the above selection process multiple times as needed to continue obtaining other different types of BWP combinations. Thus, the BWPs in the BWP combination correspond to CC1 and CC3 corresponding to the target PA.

[0098] It should be noted that the position of the DC subcarrier in the terminal is related to the activated BWP combination, and more commonly, the position of the DC subcarrier is related to the BWP with the lowest frequency band and the BWP with the highest frequency band. According to the method in this embodiment, when the target PA corresponds to more than 2 CCs, the BWP combination can be determined according to the BWPs on the CC with the highest frequency band and the CC with the lowest frequency band, rather than according to the BWPs on all CCs, which can not only reduce the number of BWP combinations, but also reduce the amount of information in each BWP combination, thereby saving signaling overhead and reducing the energy consumption of the terminal and the base station.

[0099] In one embodiment, the terminal may send auxiliary information to the base station to assist the base station in determining the BWP combination information. For example, the auxiliary information may include at least one of the channel state information of the BWP and the buffer status report. The following will be described in conjunction with Figure 6 this.

[0100] Figure 6 is a schematic flowchart of another method for receiving a bandwidth part combination according to an embodiment of the present disclosure. As Figure 6 shown, the method may further include:

[0101] In step S601, determine the channel state information and the buffer status report of each BWP on the CC corresponding to the target PA.

[0102] In one embodiment, the terminal may determine the BWP status required by the base station. For example, if the base station determines the BWP combination based on the BWPs on all CCs corresponding to the target PA, the terminal may send the status of each BWP on all CCs corresponding to the target PA to the base station; or, if the base station determines the BWP combination based on the BWPs on some of the multiple CCs corresponding to the target PA, the terminal may send the status of each BWP on the partial CCs required by the base station to the base station. For example, it may be the status of each BWP on the CC with the highest frequency band and the CC with the lowest frequency band among the multiple CCs corresponding to the target PA.

[0103] In one embodiment, the status of the BWP may include at least one of the channel state information of the BWP and the buffer status report.

[0104] Among them, the channel state information may include at least one of channel power RSRP, signal-to-noise ratio SNR / SINR, channel delay, etc., and is used to indicate the channel state of the BWP. Generally speaking, the greater the channel power, the better the channel state of the BWP; the greater the signal-to-noise ratio, the better the channel state of the BWP; the smaller the channel delay, the better the channel state of the BWP. And the better the channel state of the BWP, the higher the probability that the BWP is activated. Of course, the channel state information may also include other information indicating the channel state of the BWP. This embodiment is only an exemplary illustration and is not limited.

[0105] Among them, the buffer status report may include the amount of data to be sent in the terminal, that is, the buffer data amount. Generally speaking, the smaller the buffer data amount, the more idle the channel of the BWP, and the higher the probability that the BWP is activated.

[0106] In step S602, report the channel state information and the buffer status report to the base station. Among them, the channel state information and the buffer status report are used for the base station to determine the combination information.

[0107] In one embodiment, the terminal may send at least one of channel state information and cache status report to the base station.

[0108] In one embodiment, the base station may determine at least one of the channel state and the amount of cached data of each BWP on the CC corresponding to the target PA based on at least one of the channel state information and the cache status report; and determine the combined information according to at least one of the channel state and the amount of cached data.

[0109] In one embodiment, the base station may receive information reported by multiple terminals and comprehensively determine the channel state of each BWP. For example, the base station may determine the state of the BWP according to the sum of the cached data amounts of all terminals. The specific implementation of the base station may be determined according to the actual situation and is not limited in this embodiment.

[0110] In one embodiment, the base station may determine a channel state threshold and a cached data amount threshold based on the channel state and the amount of cached data of each BWP on the CC corresponding to the target PA; wherein, the channel state of each BWP in each BWP combination in the combined information is better than the channel state threshold, and the amount of cached data is less than the cached data threshold.

[0111] In an example, the channel state threshold and the cached data amount threshold may be preset specific values. For example, at least one of a channel power threshold N1, a signal-to-noise ratio threshold N2, a channel delay threshold N3, and a cached data amount threshold N4 may be preset. Based on this, the base station may screen out all BWPs whose channel state is better than the threshold and the amount of cached data is less than the threshold according to the channel state and the amount of cached data of each BWP, and then determine the BWP combination based on the screened BWPs.

[0112] In an example, the channel state threshold and the cached data amount threshold may also be preset ratios. For example, the preset ratio may be 50%. Thus, the base station may screen out the BWPs whose channel state and cached data amount are both in the top 50% of all BWPs; or the base station may also screen out the BWPs whose channel state or cached data amount is in the top 50% of all BWPs, and then determine the BWP combination based on the screened BWPs. Among them, the top 50% of the channel state means that the channel state is better than the other 50% of the BWPs; the top 50% of the cached data amount means that the amount of cached data is less than the other 50% of the BWPs.

[0113] In one example, the base station can also determine the priority of each BWP on the CC corresponding to the target PA among all the BWPs on this CC based on the channel state and the amount of cached data on each BWP of this CC; then, based on the priority of each BWP among all the BWPs on its affiliated CC, at least one BWP combination is determined in the order from the highest priority to the lowest priority.

[0114] Among them, the priority is positively correlated with the channel state, and the priority is negatively correlated with the amount of cached data; the combined priority of each BWP combination in the combination information is positively correlated with the priority of each BWP in this combination, and the combined priority of each BWP combination in the combination information is higher than the priority threshold.

[0115] It should be noted that in this embodiment, the level of the BWP priority can essentially be regarded as the probability of this BWP being activated. The better the channel state of the BWP and the less the amount of cached data of the BWP, the higher the probability of this BWP being activated, and then it can be determined that the priority of this BWP is higher.

[0116] For example, the base station can determine the priority order of each BWP in this CC for the CC corresponding to the target PA, such as all the CCs corresponding to the target PA, or a part of all the CCs corresponding to the target PA, respectively.

[0117] For example, for Figure 5 CC1 - CC3, the priority order of each BWP in each CC can be determined respectively. For example, for the 4 BWPs on CC1, their priority order from the highest to the lowest can be BWP11, BWP12, BWP13, BWP14; for the 4 BWPs on CC2, their priority order from the highest to the lowest can be BWP21, BWP22, BWP23, BWP24; for the 4 BWPs on CC3, their priority order from the highest to the lowest can be BWP31, BWP32, BWP33, BWP34.

[0118] After determining the priority of each BWP, the base station can determine the BWP combination according to the priority of each BWP to form BWP combination information. In this BWP combination information, each BWP combination corresponds to a combined priority, and the order of this BWP combined priority can be determined according to the priority of each BWP in this BWP combination.

[0119] For example, the base station can determine the combined priority of the BWP combination in the order from the smallest to the largest of the sum of the priority orders of each BWP in the BWP combination. For example, for the BWP with the highest priority in the CC, the BWP combination with the highest combined priority can be formed; then, in the order of the decrease of each BWP priority, the BWP combination with the decreasing combined priority can be determined. For example Figure 5Among CC1 - CC3, the BWP combination with the highest combined priority can be BWP11, BWP21, BWP31, and the sum of the priority orders of each BWP in this BWP combination is 3; then it can be determined that the BWP combination with the second - highest combined priority can be one of the following three combinations where the sum of the priority orders of each BWP is 4: BWP12, BWP21, BWP31; BWP11, BWP22, BWP31; BWP11, BWP21, BWP32. Of course, for the priority orders of the above - mentioned three combinations, the base station can determine them according to the actual situation. For example, it can directly determine the priority order according to the sequence number size, or randomly determine the priority order, or determine the priority order according to the sum of the BWP cache data volumes, etc. This embodiment does not make a limitation. Using the same method, the base station can continue to determine BWP combinations with lower combined priorities, which will not be elaborated here.

[0120] In one example, the base station can determine the BWP combination information according to the combined priority of the BWP combination. For example, the base station can preset a priority threshold, and then the BWP combination with a combined priority higher than the preset threshold forms the BWP combination information. For example, the base station can preset the priority threshold as a ratio (such as 50%), and then form the BWP combination information with the BWP combinations whose combined priorities are in the top 50%.

[0121] Alternatively, the base station can also determine the number of types of BWP combinations included in the combination information. In one example, this number can be the first number determined by the base station according to the load. Thus, the base station can determine that the combination information includes the first number of BWP combinations, and the combined priorities of these first - number BWP combinations are higher than those of other BWP combinations.

[0122] According to the above - mentioned embodiment, the base station can determine the BWP combination information according to the status of the BWP. Thus, the probability that each BWP combination in the BWP combination information is activated is higher than that of other BWP combinations, and the probability that the base station needs to query its corresponding DC sub - carrier position is also higher. For BWP combinations with a lower activation probability, the probability that the base station queries their corresponding DC sub - carrier positions is also lower. Therefore, the base station can not obtain the DC sub - carrier positions with a lower query probability, reducing the signaling overhead and performance pressure on the premise of not affecting the basic functions; at the same time, the mapping relationships that the base station needs to save are also fewer, reducing both the storage pressure and accelerating the speed of subsequent querying the DC sub - carrier positions according to the activated BWP combinations.

[0123] In one embodiment, after determining the priority of the BWP combination, the base station can send the priority of each BWP combination in the combination information to the terminal for the terminal to determine the transmission order of the DC sub - carrier positions based on the priority.

[0124] In one embodiment, the terminal may receive the priority information of the at least one BWP combination sent by the base station, and determine the transmission order of the DC subcarrier positions according to the priority information. Thus, when the terminal sends the mapping relationship between each BWP combination and the DC subcarrier position to the base station, it may send the mapping relationship to the base station according to the transmission order.

[0125] In one example, when the base station sends BWP combination information to the terminal, it may send the BWP combination and the corresponding priority identifier; or the base station may determine the arrangement order of the BWP combinations in the BWP combination information according to the priority order, for example, determine the order of each BWP combination from front to back in the BWP combination information from high to low or from low to high in priority. Thus, the terminal may determine the priority of the BWP combinations according to the order from front to back.

[0126] In one example, the terminal may send the DC subcarrier positions in the order of the priorities of the BWP combinations from high to low. For example, it may send the identifier of the BWP combination and the corresponding DC subcarrier position, or it may also directly send the DC subcarrier positions, etc. For the specific method, reference may be made to Figure 3 the method of the illustrated embodiment, which will not be elaborated here.

[0127] In one embodiment, when the base station receives the DC subcarrier positions sent by the terminal, it may not receive all the DC subcarrier positions, but receive a part of them in order.

[0128] It should be noted that since the terminal sends the DC subcarrier positions according to the combination priorities of the BWP combinations corresponding to the DC subcarrier positions, the base station receives the DC subcarrier positions corresponding to the BWP combinations with higher combination priorities in the order of the combination priorities from high to low. For the BWP combinations with higher combination priorities, the probability that the terminal activates each BWP in the BWP combination is higher, so the probability that the base station needs to query its corresponding DC subcarrier position is also higher; while for the BWP combinations with lower combination priorities, the probability that the terminal activates each BWP in the BWP combination is lower, so the probability that the base station needs to query its corresponding DC subcarrier position is also lower. For the DC subcarrier positions with lower usage probabilities, the terminal may not receive them to reduce the performance pressure, or it may also speed up the query speed of the DC subcarrier positions.

[0129] In one example, the base station may determine a second quantity of the BWP combinations to be received according to the load of the base station; and then receive the DC subcarrier positions of the second quantity.

[0130] Among them, the second quantity is negatively correlated with the load of the base station. That is to say, the higher the load of the base station, the fewer the number of DC subcarrier positions received by the base station, and the lower the load of the base station, the more the number of DC subcarrier positions received by the base station.

[0131] In one example, the second quantity may also be the same as the number of BWP combinations in the combined information, that is, all are received. For example, it may also be the first quantity in the above embodiments, etc. This embodiment does not make a limitation.

[0132] Figure 7 FIG. is a schematic flowchart of a method for transmitting a bandwidth part combination according to an embodiment of the present disclosure. The method for receiving and transmitting a bandwidth part combination shown in this embodiment can be applied to a base station, and the base station includes but is not limited to a 4G base station, a 5G base station, and a 6G base station. The base station can communicate with a terminal serving as a user equipment, and the terminal includes but is not limited to electronic devices such as a mobile phone, a tablet computer, a wearable device, a sensor, and an Internet of Things device. In one embodiment, the terminal may be the terminal applicable to the method for receiving a bandwidth part combination in any of the above embodiments.

[0133] As Figure 7 shown, the method for receiving and transmitting a bandwidth part combination may include the following steps:

[0134] In step S701, send combined information of bandwidth parts (BWPs) to the terminal.

[0135] Among them, the combined information includes at least one BWP combination, and the combined information is used to instruct the terminal to determine the DC subcarrier positions corresponding to the at least one BWP combination; among them, the types of BWP combinations in the combined information are fewer than the types of combinations that can be formed by all the BWPs configured by the base station for the terminal.

[0136] In one embodiment, the base station may determine at least one BWP combination according to a preset method, and then the base station may form BWP combination information with the at least one BWP combination and send it to the terminal. Compared with the types of combinations that can be formed by all the BWPs configured for the terminal, the number of types of BWP combinations determined by the base station according to the preset method is smaller.

[0137] According to the above embodiments, the terminal can receive the BWP combination information sent by the base station, so that the terminal can send the DC subcarrier positions based on the BWP combination information, rather than sending the DC subcarrier positions of the BWP combinations that can be formed by all the configured BWPs to the base station. That is to say, the terminal can send less data, which can save signaling overhead on the one hand and reduce performance pressure on the other hand.

[0138] Figure 8It is a schematic flowchart of another method for combined transmission of bandwidth parts shown according to an embodiment of the present disclosure. As Figure 8 shown, the method further includes:

[0139] In step S801, receive the mapping relationship between each BWP combination in the at least one BWP combination sent by the terminal and the position of the DC subcarrier.

[0140] In one embodiment, after the terminal receives the combined information of BWPs, for each BWP combination in the combined information, when determining that the activated BWP is the BWP in the BWP combination, the terminal determines the position of the DC subcarrier of the terminal, and then the terminal can send the mapping relationship between each BWP combination in the combined information and the position of the DC subcarrier to the base station.

[0141] In one embodiment, the base station can receive this mapping relationship. For example, the base station can also save this mapping relationship. Subsequently, the base station can determine the position of the DC subcarrier corresponding to the currently activated BWP combination of the terminal based on the mapping relationship.

[0142] In one embodiment, the base station may not send the combined information of BWPs to the terminal in all cases, but determine whether to send it according to the specific situation of the terminal. For example, the base station can receive the power amplifier (PA) capability reported by the terminal; and based on the PA capability, determine to send the combined information to the terminal and determine the combined information.

[0143] In one embodiment, the base station can determine the number of PAs in the terminal according to the PA capability. In response to the number of PAs being less than the number of component carriers (CCs) configured in the terminal, determine to send the combined information to the terminal.

[0144] It should be noted that if the number of PAs is less than the number of CCs configured in the terminal, then at least one target PA corresponding to multiple CCs is included in the PAs of the terminal.

[0145] In one embodiment, for each target PA, the base station can determine the BWP combination information for the target PA, and each BWP in each BWP combination in the BWP combination information corresponds to a different CC in the target PA.

[0146] In one embodiment, if the number of PAs is not less than the number of CCs configured in the terminal, then each PA of the terminal corresponds to at most one CC. Since the number of BWPs on each CC is limited, generally at most 4 BWPs, therefore, the mapping relationship between all BWPs and the position of the DC subcarrier can be sent to the terminal, and the amount of information occupied is not large.

[0147] In one embodiment, the base station may determine a first quantity of the BWP combinations based on the load of the base station; wherein, the first quantity is negatively correlated with the load of the base station; wherein, the quantity of BWP combinations in the combination information is the same as the first quantity.

[0148] In one embodiment, in response to the quantity of the PAs being less than the quantity of CCs used by the terminal, it is determined that at least one target PA is included in the PAs of the terminal, and the target PA corresponds to multiple component carriers CCs; wherein, each CC corresponds to at least one BWP, and the BWPs in each BWP combination in the combination information correspond to different CCs.

[0149] In one embodiment, the type of BWP combinations in the combination information is less than the type of combinations that can be formed by all BWPs on multiple CCs corresponding to the target PA.

[0150] In one embodiment, the BWPs in the BWP combination correspond one by one to multiple CCs corresponding to the target PA. The type of BWP combinations in the combination information is less than the type of combinations that can be formed by all BWPs on multiple CCs corresponding to the target PA.

[0151] When determining the BWP combination information, the base station may determine the BWP combination according to the BWPs on all CCs corresponding to the target PA.

[0152] In one embodiment, the BWPs in the BWP combination correspond to the CC with the highest frequency band and the CC with the lowest frequency band among multiple CCs corresponding to the target PA. The type of BWP combinations in the combination information is less than the type of combinations that can be formed by all BWPs on the CC with the highest frequency band and the CC with the lowest frequency band among multiple CCs corresponding to the target PA.

[0153] When determining the BWP combination information, the base station may also determine the BWP combination according to the BWPs on some CCs among multiple CCs corresponding to the target PA. In one example, the base station may determine the BWP combination according to the BWPs on the CC with the highest frequency band and the CC with the lowest frequency band among multiple CCs corresponding to the target PA.

[0154] In one embodiment, the base station may receive the channel state information and cache status report of each BWP on the CC corresponding to the target PA sent by the terminal; based on the channel state information and cache status report, determine the channel state and cache data volume of each BWP on the CC corresponding to the target PA; determine the combination information according to the channel state and the cache data volume.

[0155] In one example, the base station may obtain channel state information and cache status reports from the terminal. In one example, the base station may also determine at least one of the channel states and cache states of each BWP in the terminal by itself.

[0156] In one embodiment, the base station determines the combined information according to the channel state and the cache data volume, including: determining a channel state threshold and a cache data volume threshold based on the channel state and cache data volume of each BWP on the CC corresponding to the target PA; wherein, the channel state of each BWP in each BWP combination in the combined information is better than the channel state threshold, and the cache data volume is less than the cache data threshold.

[0157] In one example, the base station may also only determine one of the channel state threshold and the cache data volume threshold, and determine the combined information as that the channel state of each BWP in each BWP combination is better than the channel state threshold, or the cache data volume is less than the cache data threshold.

[0158] In one embodiment, the base station determines the combined information according to the channel state and the cache data volume, including:

[0159] For the CC corresponding to the target PA, based on the channel state and cache data volume of each BWP on this CC, determine the priority of each BWP among the BWPs on this CC; wherein, the priority is positively correlated with the channel state, and the priority is negatively correlated with the cache data volume; based on the priorities of the BWPs among the BWPs on their respective CCs, determine the combined information in the order of decreasing priority; wherein, the combined priority of each BWP combination in the combined information is positively correlated with the priority of each BWP in this combination, and the combined priority of each BWP combination in the combined information is higher than the priority threshold.

[0160] In one example, the base station may determine the priority of each BWP on its respective CC according to at least one of the channel state and cache data volume of each BWP. Then, the base station may determine the BWP combination information according to the priorities of the BWPs in the BWP combination. Generally speaking, the base station may add the BWP combinations with a combined priority higher than the threshold to the BWP combination information.

[0161] According to the above embodiments, the base station can determine the BWP combination information according to the status of the BWP, so that the probability of each BWP combination in the BWP combination information being activated is relatively high compared to other BWP combinations. Therefore, the probability that the base station needs to query its corresponding DC subcarrier position is also relatively high. For BWP combinations with a relatively low activation probability, the probability that the base station queries their corresponding DC subcarrier positions is also relatively low. Therefore, the base station can not obtain the DC subcarrier positions with a relatively low query probability, reducing signaling overhead and performance pressure on the premise of ensuring that the basic functions are not affected; at the same time, the mapping relationships that the base station needs to save are also fewer, reducing both storage pressure and accelerating the subsequent speed of querying the DC subcarrier positions according to the activated BWP combinations.

[0162] In one embodiment, for each BWP combination in the combination information, determine the priority of the BWP combination based on the priority of each BWP in the combination; send the priority of each BWP combination in the combination information to the terminal for the terminal to determine the transmission order of the DC subcarrier positions based on the priority.

[0163] In one example, the terminal can send the DC subcarrier positions in the order of the priorities of the BWP combinations from high to low. For example, it can send the identifier of the BWP combination and the corresponding DC subcarrier positions, or it can also directly send the DC subcarrier positions, etc.

[0164] In one example, when the base station receives the DC subcarrier positions sent by the terminal, it may not receive all the DC subcarrier positions, but receive a part of them in order.

[0165] According to the above embodiments, the base station can determine the number of BWP combinations to be received according to the requirements. Since the reception is performed in the order of priorities from high to low, the DC subcarriers corresponding to the BWP combinations with higher combination priorities can be received first, and the probability of these DC subcarriers being used is also higher. Therefore, the base station can reduce the data received and reduce the performance pressure.

[0166] In one embodiment, receiving the DC subcarrier positions corresponding to each BWP combination in the at least one BWP combination sent by the terminal includes:

[0167] Based on the load of the base station, determine a second number of BWP combinations to be received; wherein, the second number is negatively correlated with the load of the base station; receive the DC subcarrier positions of the second number.

[0168] For the relevant embodiments on the base station side, reference can be made to the above embodiments on the terminal side, which are only briefly described here.

[0169] Corresponding to the embodiments of the bandwidth part combined reception method described above, the present disclosure also provides embodiments of a bandwidth part combined reception apparatus.

[0170] Figure 9 FIG. is a schematic block diagram of a bandwidth part combined reception apparatus shown according to an embodiment of the present disclosure. The bandwidth part combined reception apparatus shown in this embodiment can be applied to a terminal, and the terminal includes, but is not limited to, electronic devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal can communicate with a base station as a user equipment, and the base station includes, but is not limited to, 4G base stations, 5G base stations, and 6G base stations. In one embodiment, the base station can be the base station applicable to the bandwidth part combined transmission apparatus described in any subsequent embodiment.

[0171] As Figure 9 shown, the bandwidth part combined reception apparatus may include:

[0172] A combined reception module 901, configured to receive combined information of bandwidth parts (BWPs) sent by a base station, where the combined information includes at least one BWP combination, and the combined information is used to instruct the terminal to determine the direct current (DC) subcarrier positions corresponding to the at least one BWP combination. Among them, the type of BWP combination in the combined information is less than the type of combination that can be formed by all the BWPs configured by the base station for the terminal.

[0173] In one embodiment, the apparatus may further include:

[0174] A position sending module 902, configured to determine the DC subcarrier positions corresponding to each BWP combination in the at least one BWP combination; and send the mapping relationship between each BWP combination and the DC subcarrier position to the base station.

[0175] In one embodiment, the apparatus may further include:

[0176] A power amplifier (PA) capability sending module 903, configured to report the PA capability of the terminal to the base station, where the PA capability is used for the base station to determine to send the combined information to the terminal and to determine the combined information.

[0177] In one embodiment, at least one PA is provided in the terminal, the at least one PA includes at least one target PA, the target PA corresponds to multiple component carriers (CCs), and each CC corresponds to at least one BWP, and the BWPs in the BWP combination correspond to different CCs.

[0178] In one embodiment, the type of BWP combination in the combined information is less than the type of combination that can be formed by all the BWPs on the multiple CCs corresponding to the target PA.

[0179] In one embodiment, the device may further include:

[0180] A status reporting module 904, configured to determine the channel state information and cache status report of each BWP on the CC corresponding to the target PA; report the channel state information and the cache status report to the base station, where the channel state information and the cache status report are used for the base station to determine the combined information.

[0181] In one embodiment, the BWPs in the BWP combination correspond to the CC with the highest frequency band and the CC with the lowest frequency band among the multiple CCs corresponding to the target PA.

[0182] In one embodiment, the position sending module 902 is specifically configured to:

[0183] In response to the DC subcarrier position corresponding to the BWP combination being inconsistent with the default relative position, send the description information of the DC subcarrier position corresponding to the BWP combination to the base station; or, in response to the DC subcarrier position corresponding to the BWP combination being consistent with the default relative position, send preset information to the base station.

[0236] The following is a general and exemplary description of the method for combined transmission of bandwidth parts and the method for combined reception of bandwidth parts according to the present disclosure in combination with specific technical details, as follows:

[0237] In the related art, when aggregating uplink co-band carriers, the method of reporting single carriers individually cannot meet the requirement of reporting DC subcarriers when the number of PAs is less than the number of CCs. This will cause the base station demodulation to be unable to determine the subcarrier position and perform compensation processing, thus affecting the uplink demodulation performance. The method according to the present disclosure can not only solve the above problems, but also reduce the problem of excessive signaling overhead caused by reporting DC subcarriers by setting priorities by the base station.

[0238] When the terminal is configured for uplink multi-carrier carrier aggregation, the base station determines whether to transmit the BWP combination priority to the terminal according to the PA capability reported by the terminal (such as 1PA or 2PA), and the terminal feeds back the DC subcarrier positions of each BWP combination to the base station according to the priority.

[0239] When the terminal is configured for uplink multi-carrier carrier aggregation, the base station determines whether to transmit the BWP combination priority to the terminal according to the PA capability reported by the terminal (such as 1PA or 2PA), and the terminal feeds back the DC subcarrier positions to the terminal according to the received priority information.

[0240] The base station determines the PA capability according to the PA capability reported by the terminal. In one embodiment, the base station can determine the PA capability according to the dualPA-Architecture reported by the terminal in the existing protocol.

[0241] The base station determines whether to transmit the BWP combination priority to the terminal according to the PA capability reported by the terminal (such as 1PA or 2PA). In one embodiment, the base station determines whether to transmit the BWP combination priority to the terminal by judging whether the number of PAs is equal to the number of CCs when aggregating co-frequency carriers. If it is judged to be equal, there is no need; if it is judged to be unequal, it is necessary.

[0242] The BWP combination priority refers to the preferred BWP combination on the configured CC. As shown in the following figure, in one embodiment, the preferred combinations from high to low are: BWP11-BWP22-BWP31, BWP11-BWP21-BWP34, BWP14-BWP21-BWP-34,.... The determination of the priority and the number of combinations are determined according to the channel state reported by the terminal, the cached data, and the load situation of the base station scheduling.

[0243] The terminal feeds back the DC sub - carrier position to the terminal according to the received priority information. The terminal feeds back the positions of the DC sub - carriers of each BWP combination according to the above - mentioned preferred - level combinations: BWP11 - BWP22, BWP11 - BWP21, BWP14 - BWP21, …. In one embodiment, if the DC sub - carrier follows a preset rule, for example, in one embodiment, the DC sub - carrier is on the central sub - carrier of the BWP combination, the position information of the DC sub - carrier of this combination may not be reported, and only the position information of the DC sub - carriers of the BWP combinations that do not meet the preset rule needs to be reported.

[0244] The statement that the DC sub - carrier is on the central sub - carrier of the BWP combination means taking the central positions of the two outermost BWP edges in the frequency domain.

[0245] After receiving the DC sub - carrier position, the base station determines the terminal's DC sub - carrier position according to the activated BWP combination and performs certain processing during demodulation to ensure the demodulation performance.

[0246] In another embodiment, when the base station notifies the BWP combination priority to the terminal, the BWP combination does not include the BWP indications on all CCs, but only needs to include the BWP combination indications on the two outermost CCs. For example, the preferred - level order from high to low is: BWP12 - BWP33, BWP14 - BWP34, …. The determination of the priority and the number of combinations are determined according to the channel state reported by the terminal, the buffered data, and the load situation of the base - station scheduling.

[0247] When the terminal is configured for uplink multi - carrier carrier aggregation, the base station determines whether to transmit the BWP combination priority to the terminal according to the PA capability reported by the terminal (such as 1PA or 2PA), and the terminal feeds back the DC sub - carrier position to the terminal according to the received priority information.

[0248] In another embodiment, according to the PA capability reported by the terminal, the base station can not only determine the number of PAs according to the dualPA - Architecture reported by the terminal in the existing protocol, but also include the maximum bandwidth information supported by the two PAs reported by the terminal. For example, taking the terminal configured with 3 CCs as an example, the maximum channel bandwidth supported by PA1 can cover two CCs, such as CC1 and CC2, while the maximum channel bandwidth supported by PA2 can only cover one CC, such as CC3.

[0249] In this case, the number of CCs is 3 and the number of PAs is 2. Therefore, the base station determines that it needs to transmit the BWP combination priority to the terminal according to the PA capability reported by the terminal.

[0250] Meanwhile, based on the bandwidth information of the PA, determine the BWP combination priorities to be transmitted to the terminal on two CCs of PA1, without considering CC3. That is, the reported priority combinations only include CC1 and CC2, such as: BWP11-BWP22, BWP11-BWP21, BWP14-BWP21, …. The determination of the priorities and the number of combinations are determined according to the channel state reported by the terminal, the cached data, and the load situation of the base station scheduling.

[0251] In one embodiment, the above method is not only applicable to multi-UL CA, but also applicable to a dual-link system, i.e., DC.
