Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a direct current carrier position reporting method, terminal equipment, and network equipment. Background Art

[0002] In wireless communications, modulation is the primary method for shifting signal spectrum. A mixer performs nonlinear operations on the input signal and the modulated carrier, generating sum / difference frequency signals of the two signals. The desired high-order frequency signals are then filtered out, completing spectrum shifting from low to high frequencies. For a modulated carrier of a broadband signal, the center frequency is typically referred to as the direct current (DC) carrier.

[0003] In the Orthogonal Frequency Division Multiplexing (OFDM) modulation method, there is usually strong signal interference at the DC position. This carrier needs to be removed in the receiver to improve the received signal-to-noise ratio. Therefore, the receiver needs to know the exact position of this DC. The DC position is usually notified to the receiving end by the transmitter. Taking uplink communication as an example, the terminal needs to inform the base station of the exact DC position of its transmitted signal so that the base station can accurately remove the subcarrier at the DC position. In the new radio (NR) technology, the DC position is reported to the base station by the terminal device through radio resource control (RRC) signaling.

[0004] In the case of a single carrier, the terminal device reports a DC position for each BWP configured for that carrier, and this position depends on the terminal implementation. For the case of simultaneous operation of multiple carriers in the same band, as the number of carriers increases, the total number of BWPs also increases exponentially. Therefore, there are many possible DC positions in the terminal implementation, resulting in excessive signaling overhead for the terminal to report the DC position. Summary of the Invention

[0059] 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.

[0060] In the NR system, taking uplink communication as an example, the terminal device reports the DC location to the base station through RRC signaling.

[0061] The NR system introduces the concept of bandwidth part (BWP). To save power, the base station usually configures a smaller transmit and receive bandwidth for the terminal, thereby reducing the complexity of the terminal transmitting and receiving signals. Figure 2 Is a BWP schematic diagram, Figure 2 In the frequency band, there are multiple channels / carriers. After the terminal accesses a channel / carrier, the base station will further configure no more than four BWPs for each carrier / channel. Only one BWP can be activated at a time. The terminal's subsequent communications will work in this activated BWP. BWP configuration is achieved through RRC signaling, such as using RRC reconfiguration messages for semi-static configuration. BWP activation is activated through downlink control information (DCI) in the physical downlink control channel (PDCCH), which is a dynamic configuration process.

[0062] After the base station configures the BWP through the RRC Reconfiguration message, the minimum operating bandwidth of the terminal's RF receive and transmit paths will be greater than or equal to the width of the BWP. The specific implementation depends on the terminal. Figure 3A and 3B The following diagrams show two DC location reporting methods of terminal devices based on BWP. Figure 3A As shown, in method 1, the terminal adjusts the DC position according to the position of the activated BWP; Figure 3B As shown, in the second mode, the terminal uses the same DC position for all activated BWPs.

[0063] As can be seen, the related art reports the DC position based on the configured BWP. For example, for each BWP, the terminal reports the corresponding DC position through the uplink transmission DC list (uplinkTxDirectCurrentList) message in the RRC Reconfiguration Complete message to adapt to different terminal implementations. For a single carrier, the terminal reports a maximum of four DC positions when the BWP is activated to the base station.

[0064] In NR, the base station usually configures the component carrier (CC) for the terminal through RRC signaling to form carrier aggregation (CA) or dual connectivity (DC); and further activates the component carrier through MAC signaling to put the component carrier into a working state, or deactivates it to put the component carrier into a non-working state. It can be seen that the component carrier in CA or DC needs to go through two operation processes: RRC signaling configuration and MAC signaling activation / deactivation. This is mainly to take into account the signaling overhead and timeliness. RRC signaling will complete the configuration process of the component carrier information. Usually, this process carries more signaling messages and is slower; while the two operations of MAC signaling activation or deactivation are faster and more convenient, and can quickly respond to business needs as needed according to actual conditions.

[0065] As mentioned earlier, the current single-carrier DC position reporting for terminals is based on each configured BWP, with the position being determined by the terminal implementation. For simultaneous intra-band multi-carrier operation, the total number of BWPs increases exponentially with the number of carriers. For example, in intra-band CA, a terminal typically uses a single PA to support the entire bandwidth. Figure 4 This is a schematic diagram of BWP under CA, such as Figure 4As shown in FIG, when the network is configured with two component carriers (CCs) (carriers for short), and each carrier is configured with four BWPs, there are multiple possibilities for the DC position of the terminal in implementation.

[0066] Generally speaking, when a single PA is used to support intra-band CA (carrier aggregation), the terminal modulates the two activated BWPs together to complete the spectrum shift, that is, there is only one DC position. Figure 4 For example, in Figure 4 In the case of two carriers shown, there are 4x4=16 potential BWP combinations, and correspondingly 16 potential DC positions. Currently, the DC position for two-carrier CA is reported in RRC signaling by reporting the DC positions corresponding to all BWP combinations.

[0067] As the number of carriers in CA increases, the number of simultaneously activated BWP combinations also increases exponentially. If the aforementioned BWP (or BWP combination) reporting method is still used, the potential DC locations will also increase exponentially, making signaling design unbearable. Therefore, it is necessary to study how to solve the problem of reporting DC locations in multi-carrier scenarios while maintaining a certain signaling complexity.

[0068] The present application embodiment proposes a method for reporting a DC carrier (DC) position. Figure 5 is a schematic flow chart of a DC location reporting method 500 according to an embodiment of the present application, which can optionally be applied to Figure 1 The system shown in the figure is not limited thereto. The method includes at least part of the following contents.

[0069] S510: The terminal device determines a component carrier (CC) / bandwidth part (BWP) in an activated state;

[0070] S520: The terminal device sends the DC position corresponding to the activated CC / BWP.

[0071] As described in the background section above, when a terminal is configured for intra-band multi-carrier operation (carrier 1…carrier n), such as CA (intra-band continuous CA or intra-band non-continuous CA) or dual connectivity, the terminal reports the DC position for all BWP combinations on all configured carriers. For example, if the network configures carrier 1 and carrier 2 for the terminal, and four BWPs are configured on carrier 1 and four BWPs are configured on carrier 2, the terminal will report all DC positions corresponding to all BWP combinations on these two carriers (one BWP per carrier constitutes a BWP combination, for a total of 16 possible BWP combinations). This approach has little impact on signaling with two component carriers, but when the number of component carriers increases (for example, to eight), the number of BWP combinations on all CCs will become very large, making it difficult to report the DC positions corresponding to the BWP combinations of all configured carriers.

[0072] In order to solve this problem, the DC position reporting method proposed in the embodiment of the present application starts from how to reduce the BWP combination, and reduces the reporting signaling overhead by reporting the DC position corresponding to the CC or BWP in the activated state.

[0073] In some implementations, after the terminal device has determined the CC in the activated state, sending the DC position corresponding to the CC in the activated state in step S520 may include:

[0074] Determine at least one first BWP combination, where the first BWP combination is a BWP combination of CCs in an activated state;

[0075] A DC position corresponding to each first BWP combination in the at least one first BWP combination is transmitted.

[0076] The above implementation is described in detail below using Example 1.

[0077] Example 1:

[0078] This embodiment implements DC position reporting based on an activated CC.

[0079] Figure 6 This is a schematic diagram of activating carriers and configuring carriers involved in Example 1. Figure 6 As shown in FIG, the network device configures n component carriers for the terminal device, but in practice not all component carriers are in an activated state. Figure 6 If only carrier 1 and carrier 2 are activated, then carriers 3 to n will not affect the DC position. In this case, the DC position report can only consider carrier 1 and carrier 2. It should be noted that Figure 6The DC position corresponding to carrier 1 + carrier 2 is based on the DC position when carrier 1 + carrier 2 + ... + carrier n are configured and activated. It may be different from the DC position when only carrier 1 and carrier 2 are configured in the network.

[0080] by Figure 6 Taking the component carriers in the example, for example, the activated component carriers include carrier 1 and carrier 2, then there are 4*3=12 BWP combinations of carrier 1 and carrier 2 (i.e., the first BWP combination mentioned above). Specifically, carrier 1 and carrier 2 each take one BWP to form a first BWP combination, and there are 12 possible combinations, including BWP1+BWPx, BWP1+BWPy, BWP1+BWPz, BWP2+BWPx, BWP2+BWPy, BWP2+BWPz, BWP3+BWPx, BWP3+BWPy, BWP3+BWPz, BWP4+BWPx, BWP4+BWPy, and BWP4+BWPz.

[0081] The terminal device may report the DC position corresponding to each first BWP combination to the base station. Since the number of component carriers in the activated state is limited, the terminal device may report the DC positions corresponding to all first BWP combinations of component carriers in the activated state.

[0082] In some embodiments, the terminal device may send the DC position corresponding to each first BWP combination in the at least one first BWP combination via medium access control (MAC) signaling. Since carrier activation and deactivation are implemented through MAC signaling, the DC position reporting by the terminal device based on MAC signaling is shorter and more timely than reporting based on RRC signaling.

[0083] Alternatively, the terminal device may also send the DC position corresponding to each first BWP combination in the at least one first BWP combination through RRC signaling.

[0084] In some implementations, when a terminal device uses N L0s to up-convert all CCs, each first BWP combination corresponds to N DC positions, where N is a positive integer. For example, when the terminal device uses one L0 to up-convert all carriers, each first BWP combination corresponds to one DC position; when the terminal device uses two L0s to up-convert all carriers, each first BWP combination corresponds to two DC positions.

[0085] As can be seen from the above, reporting DC positions based on activated CCs can reduce the number of DC positions that need to be reported, thereby reducing signaling overhead. The fewer the number of activated CCs, the more obvious this advantage is. However, when the network activates more than a certain number of CCs for terminal devices, reporting the positions of all BWPs based on activated CCs may not be advantageous. First, when the number of activated carriers is large, the number of all BWP combinations is already large. In addition, as business needs demand, the network may activate and deactivate carriers more frequently. At this time, if the terminal frequently reports a large number of DC positions, the signaling load may increase over time.

[0086] In view of this, in an embodiment of the present application, when the number of CCs in the activated state is less than or equal to the first threshold, the terminal device can send the DC position corresponding to each first BWP combination in the at least one first BWP combination. In this way, when there are fewer CCs in the activated state, the corresponding DC position is reported. At this time, the number of first BWP combinations of CCs in the activated state is relatively small, and therefore the number of reported DC positions is also relatively small.

[0087] Furthermore, when the number of CCs in the activated state is large, such as greater than the above-mentioned first threshold, the terminal device can report the DC position corresponding to the second BWP combination of the possible CC combinations in the activated state at one time; wherein, the aforementioned possible CC combination in the activated state can be called the first CC combination, and the number of CCs contained in the first CC combination is greater than the above-mentioned first threshold.

[0088] Specifically, the following steps may be included:

[0089] The terminal device determines at least one first CC combination, where the number of CCs included in the first CC combination is greater than the first threshold;

[0090] determining at least one second BWP combination for each first CC combination of the at least one first CC combination;

[0091] The DC position corresponding to each second BWP combination in the at least one second BWP combination is sent.

[0092] The following example uses the configuration of 8 CCs for terminal devices on the network to illustrate:

[0093] After the network configures 8 component carriers for the terminal device, the possible number of activated carriers ranges from 1 to 8. Assuming that the above-mentioned first threshold is 5, then when the number of carriers activated by the network at a certain moment is less than or equal to the first threshold (i.e., 5) carriers, taking the activation of 4 component carriers as an example, the terminal device can report the DC positions corresponding to all first BWP combinations of the 4 activated CCs to the base station through MAC signaling or RRC signaling. Since the 4 activated carriers are known at this time, that is, it is known which 4 carriers are activated, it is only necessary to report the DC positions corresponding to all BWP combinations in these 4 activated carriers.

[0094] When the number of activated carriers is the same but the activated carriers are different, all DC positions corresponding to the activated carriers need to be re-reported. Figure 7 A case where the number of activated carriers is the same but different is shown. Figure 7 In the example, the terminal device is configured with eight carriers, including carriers 1 through 8. At the previous moment, the network device activated carriers 1, 2, 4, and 5 for the terminal device. At the next moment, the network device activated carriers 1, 2, 3, and 4 for the terminal device. The number of activated carriers at both moments is the same, but the specific carriers are different. The terminal device needs to report the possible DC location for each case separately.

[0095] For the case where the number of carriers in an activated state is greater than the above-mentioned first threshold, in an embodiment of the present application, after the network initially configures the component carrier through RRC signaling, the terminal device may report in advance the DC position corresponding to the possible combination of CCs in an activated state (such as the above-mentioned first CC combination), where the number of CCs included in the possible combination of CCs in an activated state is greater than the above-mentioned first threshold.

[0096] Taking the configuration of 8 CCs and the first threshold equal to 5 as an example, after receiving the RRC signaling for configuring the CC, the terminal device can report the DC position corresponding to the subsequent possible activated CC combination (such as the first CC combination mentioned above, where the number of CCs contained in the combination is greater than 5) to the base station through the RRC Reconfiguration complete message.

[0097] For example, taking the configuration of 8 CCs as an example, there are 28 CC combinations including 6 activated CCs, 8 CC combinations including 7 activated CCs, and 1 CC combination including 8 activated CCs. The terminal device first determines these possible combinations of CCs in the activated state, then determines the BWP combination for each CC combination (i.e., the second BWP combination mentioned above), and determines the DC position corresponding to each BWP combination, and reports these DC positions to the base station through the RRC Reconfiguration Complete message.

[0098] In some implementations, when the terminal device uses N L0s to up-convert all CCs, each of the second BWP combinations corresponds to N DC positions; where N is a positive integer.

[0099] It can be seen that the number of reported carriers is many times greater than when the number of activated CCs is less than or equal to the first threshold. This is because when the number of activated CCs is less than or equal to the first threshold, DC reporting is based on known activated carriers; when the number of activated CCs is greater than the first threshold, DC reporting needs to consider various possible activated carrier combinations.

[0100] In summary, when the network configures 8 component carriers for the terminal through RRC reconfiguration signaling, and the set first threshold is equal to 5, the terminal device can report all possible DC positions of 6, 7, and 8 activated carriers to the network through the RRC reconfiguration complete message. For the case where the number of activated carriers is less than or equal to 5, the terminal will complete the reporting of all DCs corresponding to these activated carriers through MAC signaling or RRC signaling according to the actual activated carriers.

[0101] The specific values ​​such as the number of component carriers and the value of the first threshold are only examples and are not limited in this application.

[0102] Moreover, the above-mentioned use of the first threshold is only an example, and the embodiments of the present application may adopt other methods. For example, when the number of CCs in the activated state is less than the first threshold, the terminal device sends the DC position corresponding to at least one first BWP combination of the CCs in the activated state; and the terminal device sends the DC positions corresponding to the possible combinations of CCs in the activated state to the base station at one time, where the number of CCs contained in the combination of CCs in the activated state is greater than or equal to the first threshold. Taking the configuration of 8 component carriers and the setting of the first threshold equal to 5 as an example, the terminal device can report all possible DC positions of 5, 6, 7, and 8 activated carriers to the network through the RRC reconfiguration complete message. For the case where the number of activated carriers is less than 5, the terminal will complete the reporting of all DCs corresponding to these activated carriers through MAC signaling or RRC signaling according to the actually activated carriers.

[0103] In addition, the first threshold may be a preset value, or the terminal device may receive the first threshold from the network device. In some implementations, the terminal device may receive an RRC reconfiguration message for configuring a CC, the RRC reconfiguration message for configuring a CC carrying the first threshold.

[0104] The above introduces the DC position reporting method based on the activated carrier, which can reduce the signaling overhead of reporting the DC position to a certain extent. This method first determines the activated carrier, and then reports the DC positions corresponding to all possible BWP combinations under the activated carrier to the network. Another more direct way is to report the DC position based on the activated BWP. For example, the terminal device sends the DC position corresponding to the activated BWP (or BWP combination) through the physical uplink control channel (PUCCH, Physical Uplink Control Channel) uplink control information (UCI, Uplink Control Information) message and / or the physical uplink shared channel (PUSCH, Physical Uplink Shared Channel) message.

[0105] The following uses Example 2 to introduce DC position reporting based on activating BWP.

[0106] Example 2:

[0107] In related technologies, the BWP is configured by the base station for each CC through an RRC Reconfiguration message, and is dynamically activated and deactivated through the DCI in the PDCCH. Figure 8 is a schematic diagram of activating BWP, such as Figure 8As shown in the figure, 4 BWPs are configured on the carrier, but only one BWP is activated for an activated carrier at the same time. Figure 8 BWP1 is activated in

[0108] Figure 9 This is a diagram of the DC position reporting method based on the activation of BWP. Figure 9 In this example, the network device configures eight CCs for the terminal device, including carriers 1 through 8, but only activates carriers 1 and 2. Four BWPs are configured on carriers 1 and 2, respectively, but at a given moment, only BWP1 on carrier 1 and BWP2 on carrier 2 are activated. In this case, the terminal device only needs to report the DC position corresponding to the combination of BWP1 on carrier 1 and BWP2 on carrier 2 to the network.

[0109] In some implementations, when the terminal device uses N L0s to up-convert all CCs, each of the above-mentioned activated BWPs corresponds to N DC positions; where N is a positive integer.

[0110] In contrast, in the above case, the carrier-based DC position reporting method in Example 1 needs to consider the DC positions corresponding to the 16 BWP combinations on carriers 1 and 2 and report them to the network. Therefore, the DC position reporting based on the activated BWP combination in this embodiment can significantly reduce signaling overhead.

[0111] In some embodiments, after receiving the PDCCH DCI for activating / deactivating the BWP, the terminal device sends the DC position corresponding to the BWP in the activated state.

[0112] In addition, in this embodiment, when the number of CCs in the activated state is less than or equal to the second threshold, the terminal device may send the DC position corresponding to the BWP in the activated state.

[0113] Similar to Example 1, further, when the number of CCs in the activated state is large, such as greater than the above-mentioned second threshold, the terminal device can report the DC positions corresponding to all BWP combinations of CC combinations that may appear in the activated state at one time; wherein, the number of CCs included in the aforementioned CC combinations that may appear in the activated state is greater than the above-mentioned second threshold.

[0114] The second threshold may be a pre-set value, and is also notified by the network device to the terminal device when configuring a CC for the terminal device. For example, the terminal device receives an RRC reconfiguration message for configuring a CC, and the RRC reconfiguration message for configuring a CC carries the second threshold.

[0115] Taking the case where the network configures 8 CCs for the terminal device and the second threshold is equal to 5 as an example, after receiving the RRC signaling for configuring the CC, the terminal device can report the DC positions corresponding to the subsequent possible activated CC combinations (the number of CCs contained in the combination is greater than 5) to the base station through the RRC Reconfiguration Complete message.

[0116] Afterwards, after the network activates the CC and the BWP in the CC for the terminal device, if the number of activated CCs is less than or equal to the second threshold (such as the number of activated CCs is 1, 2, 3, 4 or 5), the terminal device reports the DC position corresponding to the activated BWP to the network.

[0117] Compared to Example 1, this embodiment can reduce signaling overhead. Since PDCCH DCI activation of BWP may be more frequent than MAC signaling activation of carrier, the DC position reporting delay requirement based on BWP activation is higher and the reporting frequency is also more frequent. To this end, this application proposes the following implementation methods.

[0118] Implementation three:

[0119] After activating CC for a terminal device, the base station sends the BWP combinations to be activated to the terminal. The terminal completes the DC position setting for these BWP combinations and reports the DC position. In this way, when the base station subsequently activates a BWP combination, the terminal device no longer needs to provide the DC position corresponding to the BWP combination.

[0120] Specifically, when the CC in the activated state has been determined, the terminal device receives the BWP combination to be activated corresponding to the CC in the activated state from the network device.

[0121] In some implementations, the terminal device may receive the BWP combination to be activated corresponding to the activated CC from the network device through at least one of RRC signaling, MAC signaling, and PDCCH DCI.

[0122] Afterwards, the terminal device sends the DC position corresponding to the BWP combination to be activated. Specifically, the terminal device can send the DC position corresponding to the BWP combination to be activated through at least one of RRC signaling, MAC signaling, PUCCH message and PUSCH message.

[0123] In some implementations, when the terminal device uses N L0s to up-convert all CCs, each of the BWP combinations to be activated corresponds to N DC positions, where N is a positive integer.

[0124] Take Table 1 as an example:

[0125] Table 1

[0126]

[0127] As shown in Table 1, when the component carriers in the terminal device's activated state include CC1 and CC2, the base station sends the BWP combinations of CC1 and CC2 to be activated to the terminal device, and the terminal device feeds back the DC positions corresponding to these BWP combinations to be activated to the base station.

[0128] In addition, in this embodiment, when the number of CCs in the activated state is less than or equal to the third threshold, the terminal device may send the DC position corresponding to the BWP combination to be activated.

[0129] Similar to Example 1, further, when the number of CCs in the activated state is large, such as greater than the above-mentioned third threshold, the terminal device can report the DC positions corresponding to all BWP combinations of CC combinations that may appear in the activated state at one time; wherein, the number of CCs included in the aforementioned CC combinations that may appear in the activated state is greater than the above-mentioned third threshold.

[0130] The third threshold may be a pre-set value, and is also notified by the network device to the terminal device when configuring a CC for the terminal device. For example, the terminal device receives an RRC reconfiguration message for configuring a CC, and the RRC reconfiguration message for configuring a CC carries the third threshold.

[0131] Taking the case where the network configures 8 CCs for the terminal device and the second threshold is equal to 5 as an example, after receiving the RRC signaling for configuring the CC, the terminal device can report the DC positions corresponding to the subsequent possible activated CC combinations (the number of CCs contained in the combination is greater than 5) to the base station through the RRC Reconfiguration Complete message.

[0132] After the network activates CCs for the terminal device, if the number of activated CCs is less than or equal to the second threshold (such as the number of activated CCs is 1, 2, 3, 4 or 5), the terminal device reports to the network the DC position corresponding to the BWP combination of the activated CC to be activated.

[0133] It can be seen that this embodiment can reduce signaling overhead and does not require frequent reporting of the DC location due to frequent switching of BWPs in the network, so the requirement for reporting delay is relatively low.

[0134] The present application also proposes a DC carrier (DC) position receiving method. Figure 10is a schematic flow chart of a DC position receiving method 1000 according to an embodiment of the present application, which can optionally be applied to Figure 1 The system shown in the figure is not limited thereto. The method includes at least part of the following contents.

[0135] S1010: The network device receives a DC position corresponding to an activated CC / BWP from the terminal device.

[0136] In some implementations, the network device is a base station.

[0137] In some embodiments, the DC position corresponding to the activated CC includes: a DC position corresponding to a first BWP combination, wherein the first BWP combination is a BWP combination of the activated CC.

[0138] The first BWP combination may include all possible combinations of activated BWPs for activated CCs. For example, among the component carriers of a terminal device, CC1 and CC2 are activated, 4 BWPs are configured in CC1, and 3 BWPs are configured in CC2. Then, CC1 and CC2 each take one BWP to form a first BWP combination, for a total of 4*3=12 first BWP combinations. The network device may receive the DC positions corresponding to all first BWP combinations reported by the terminal device.

[0139] In some embodiments, the network device receives the DC position corresponding to the first BWP combination via MAC signaling. Since carrier activation and deactivation are implemented via MAC signaling, the terminal device's DC position reporting based on MAC signaling is shorter and more timely than reporting based on RRC signaling.

[0140] Alternatively, the network device receives the DC position corresponding to the first BWP combination through RRC signaling.

[0141] In some implementations, when the terminal device uses N L0s to up-convert all CCs, each first BWP combination corresponds to N DC positions; where N is a positive integer.

[0142] As can be seen from the above, the network device receiving the DC positions of the activated CCs can reduce the number of DC positions that need to be received, thereby reducing signaling overhead. The fewer the number of activated CCs, the more obvious this advantage is.

[0143] Furthermore, in an embodiment of the present application, when the number of CCs in the terminal device that are in an activated state is less than or equal to a first threshold, the network device may receive a DC position corresponding to at least one first BWP combination of the CCs in the activated state.

[0144] Furthermore, if the number of activated CCs is large, such as greater than the first threshold, the network device may receive a DC position reported by the terminal device all at once. For example, the network device receives from the terminal device the DC position corresponding to at least one second BWP combination of a first CC combination, where the number of CCs included in the first CC combination is greater than the first threshold.

[0145] In some implementations, the network device receives the DC position corresponding to the at least one second BWP combination of the first CC combination via an RRC reconfiguration complete message.

[0146] In some implementations, when the terminal device uses N L0s to up-convert all CCs, each of the second BWP combinations corresponds to N DC positions; where N is a positive integer.

[0147] The first threshold may be a pre-set value or may be sent by the network device to the terminal device. In some implementations, the network device sends an RRC reconfiguration message for configuring a CC to the terminal device, and the RRC reconfiguration message for configuring a CC carries the first threshold.

[0148] In some implementations, the network device receives the DC position corresponding to the activated BWP via a PUCCH UCI message and / or a PUSCH message.

[0149] For example, before receiving the DC position, the network device sends a PDCCH DCI for activating / deactivating the BWP to the terminal device. After receiving the PDCCH DCI for activating / deactivating the BWP, the terminal determines the currently activated BWP and sends the DC position corresponding to the activated BWP to the network device through a PUCCH UCI message and / or a PUSCH message.

[0150] In addition, in this embodiment, when the number of CCs in the terminal device that are in an activated state is less than or equal to a second threshold, the network device may receive the DC position corresponding to the BWP in the activated state. When the number of component carriers in the activated state is large, such as greater than the second threshold, the network device may receive the DC positions corresponding to all BWP combinations of the component carrier combinations in the activated state reported by the terminal device at one time; wherein the number of CCs included in the aforementioned possible component carrier combinations in the activated state is greater than the second threshold.

[0151] To avoid the issue of frequent DC position reception caused by frequent switching of activated BWPs, in some implementations, the network device can send the terminal device the BWP combinations that are about to be activated, corresponding to the activated CCs. The network device then receives the DC positions corresponding to these BWP combinations from the terminal device. This eliminates the need for the network device to receive the DC positions corresponding to a BWP combination when subsequently activating that BWP combination, potentially reducing reception frequency.

[0152] In some implementations, when the terminal device uses N L0s to up-convert all CCs, each of the BWP combinations to be activated corresponds to N DC positions; where N is a positive integer.

[0153] In some implementations, the network device sends the BWP combination to be activated corresponding to the CC in the activated state to the terminal device through at least one of RRC signaling, MAC signaling, and PDCCH DCI.

[0154] The network device receives the DC position corresponding to the BWP combination to be activated through at least one of RRC signaling, MAC signaling, PUCCH message and PUSCH message.

[0155] In an embodiment of the present application, when the number of CCs in the terminal device that are in an activated state is less than or equal to a third threshold, the network device can send the BWP combinations that are about to be activated corresponding to the CCs in the activated state to the terminal device, and receive the DC positions corresponding to the BWP combinations that are about to be activated.

[0156] Furthermore, if the number of activated CCs is large, such as greater than the third threshold, the network device may receive a DC position reported by the terminal device all at once. For example, the network device receives from the terminal device a DC position corresponding to at least one second BWP combination of a possible combination of activated CCs, where the number of CCs included in the possible combination of activated CCs is greater than the third threshold.
