[0029] To enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0030] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: only A, only B, and A and B. In addition, "at least one" means one or more, and "a plurality" means two or more. Expressions such as "first" and "second" do not limit the quantity and execution order, and expressions such as "first" and "second" do not necessarily limit them to be different.

[0031] It should be noted that in this disclosure, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0032] The fourth generation mobile communication technology (4G), Long-Term Evolution Advanced (LTE-Advance), and the fifth generation mobile communication technology (5G) are facing increasing demands. Based on current development trends, 4G and 5G systems are developing support for enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine type communication (mMTC). Carrier aggregation (CA) can be used as an effective means to improve cell coverage and user data rates in 4G, 5G, and other communication systems.

[0033] In current mobile communication systems, CA technology requires that, as channel conditions change, the network must configure and reconfigure carrier combinations through the Radio Resource Control (RRC) layer and instruct secondary carriers / secondary cells (Scells) to activate or deactivate them through the Medium Access Control-Control Element (MAC-CE). These semi-static notifications not only take tens of milliseconds but also prevent flexible carrier combination changes, preventing them from matching actual channel condition changes.

[0034] In view of this, the present disclosure proposes a carrier configuration method, in which a first node receives configuration signaling sent by a second node, the configuration signaling being used to determine configuration information for a carrier combination; the first node and the second node then perform multi-carrier communication based on the carrier combination configuration information. In this way, based on different channel states, the second node can promptly send different configuration signaling to the first node, allowing the first and second nodes to perform multi-carrier communication based on the configuration information for different carrier combinations determined by the different configuration signaling. This achieves dynamic configuration of the carrier combination to match the actual channel state, thereby improving communication efficiency.

[0035] The carrier configuration method provided in the embodiments of the present disclosure can be applied to systems of various communication standards. For example, the carrier configuration method provided in the embodiments of the present disclosure can be applied to systems including, but not limited to, LTE systems, various versions based on LTE evolution, 5G systems, and other communication systems. In addition, the method for sending and receiving system messages provided in the embodiments of the present disclosure can also be applied to future-oriented communication systems (e.g., 6G communication systems).

[0036] The network architecture of the mobile communication network (including but not limited to 3G, 4G, 5G and future mobile communication networks) in the embodiment of the present disclosure may include at least a first communication node and a second communication node. It should be understood that in this example, in the downlink, the first communication node may be a network side device (for example, including but not limited to a base station), and the second communication node may be a terminal side device (for example, including but not limited to a terminal). Of course, in the uplink, the first communication node may also be a terminal side device, and the second communication node may also be a network side device. In the device-to-device communication between the two communication nodes, the first communication node and the second communication node may both be a base station or a terminal. The first communication node and the second communication node may be referred to as the first node and the second node, respectively.

[0037] For example, taking the first communication node as a terminal and the second communication node as a base station, as shown in FIG1 , a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure is shown. The communication system includes a terminal 10 and a base station 20. The number of terminals 10 and base stations 20 can be one or more, and the number is not limited here.

[0038] In some embodiments, base station 20 provides wireless access services to terminal 10. A base station 20 provides at least one service coverage area (also referred to as a cell). Terminal 10 entering this area can communicate with base station 20 via wireless signals to receive the wireless access services provided by base station 20.

[0039] In some embodiments, the base station can be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station device in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, home base stations, wireless remote devices, reconfigurable intelligent surfaces (RISs), routers, relays, TRPs, wireless fidelity (WIFI) devices and other network side devices.

[0040] In some embodiments, the terminal can be a device with wireless transceiver function. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal can sometimes also be referred to as a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication equipment, UE agent or UE device, etc., and the embodiments of the present disclosure do not limit this.

[0041] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0042] The present disclosure provides a carrier configuration method. As shown in FIG2 , the method includes the following steps S101-S102.

[0043] S101: A first node sends a configuration signaling to a second node; correspondingly, the first node receives the configuration signaling sent by the second node. The configuration signaling is used to determine configuration information of a carrier combination.

[0044] Carrier combination may also have other names, such as carrier aggregation, carrier aggregation combination (denoted as CA combination), which is not limited in this disclosure.

[0045] In some embodiments, the configuration signaling includes downlink control information (DCI). Since DCI is physical layer signaling, configuring the carrier combination through DCI shortens the configuration time compared to configuring the carrier combination through RRC signaling in some technologies (i.e., a semi-static configuration method), and enables flexible configuration of different carrier combinations to adapt to actual channel conditions.

[0046] In some embodiments, the downlink control information indicates the aggregated use of different numbers of carriers.

[0047] In some embodiments, the configuration signaling includes a bitmap, the bitmap includes multiple indication bits, each indication bit corresponds to a carrier, and each indication bit is used to indicate whether the carrier corresponding to the indication bit belongs to a carrier combination.

[0048] For example, as shown in Figure 3, it is assumed that the network side configures three carriers, namely carrier 1, carrier 2, and carrier 3. The base station sends configuration signaling to the terminal. The configuration signaling includes a bitmap with three indicator bits, namely the first indicator bit, the second indicator bit, and the third indicator bit. These three indicator bits correspond to carrier 1, carrier 2, and carrier 3, respectively. Assuming that the indicator bit is "0", the carrier corresponding to the indicator bit does not belong to the carrier combination configured by the base station for the terminal; if the indicator bit is "1", the carrier corresponding to the indicator bit belongs to the carrier combination configured by the base station for the terminal. For example, if the bitmap in the DCI sent by the base station to the terminal at time T1 is "110", it means that carrier 1 and carrier 2 belong to the carrier combination configured by the base station for the terminal, and carrier 3 does not belong to the carrier combination configured by the base station for the terminal.

[0049] In some embodiments, the carrier to be monitored by the first node is determined based on configuration information of the carrier combination.

[0050] In some embodiments, determining the carrier to be monitored by the first node based on the configuration information of the carrier combination includes at least one of the following:

[0051] Determining the carrier to be monitored by the first node based on a comparison between the number of carriers supported for monitoring by the first node and the number of carriers corresponding to the configuration information of the carrier combination;

[0052] Determining the carrier to be monitored by the first node based on a comparison between the number of carriers supported for monitoring by the first node and the number of carriers corresponding to the configuration information of the carrier combination determined by the configuration signaling received within a preset time period;

[0053] When the number of carriers corresponding to the configuration information of the carrier combination determined by the configuration signaling is equal to the number of carriers corresponding to all carriers configured on the network side, the carrier to be monitored by the first node is determined based on a comparison between the number of carriers supported for monitoring by the first node and the number of carriers corresponding to all carriers configured on the network side.

[0054] In some embodiments, the number of carrier combinations determined by the configuration signaling is one or more. When the number of determined carrier combinations is one, the carrier to be monitored by the first node is determined based on a comparison between the number of carriers supported for monitoring by the first node and the number of carriers corresponding to the carrier combination. When the number of determined carrier combinations is multiple, the carrier to be monitored by the first node is determined based on a comparison between the number of carriers supported for monitoring by the first node and the number of carriers corresponding to one or more carrier combinations in the multiple carrier combinations.

[0055] Exemplarily, continuing to refer to Figure 3, the carrier combination determined by the configuration signaling includes carrier combination 1 and carrier combination 2. Carrier combination 1 includes carrier 2 and carrier 3, and carrier combination 2 includes carrier 1 and carrier 3. The carrier to be monitored by the first node can be determined based on the comparison of the number of carriers supported by the first node for monitoring with the number of all carriers included in carrier combination 1. The carrier to be monitored by the first node can also be determined based on the comparison of the number of carriers supported by the first node for monitoring with the number of all carriers included in carrier combination 2. The carrier to be monitored by the first node can also be determined based on the comparison of the number of carriers supported by the first node for monitoring with the number of carriers included in the two carrier combinations of carrier combination 1 and carrier combination 2. Some determination methods can be determined in combination with actual communication scenarios, or pre-configured.

[0056] As another example, continuing to refer to Figure 3, during the time period from T1 to T2, the carrier combination determined by the received configuration signaling includes carrier 1 and carrier 2, corresponding to a number of carriers of 2; during the time period from T2 to T3, the carrier combination determined by the received configuration signaling includes carrier 1, carrier 2, and carrier 3, corresponding to a number of carriers of 3; during the time period from T3 to T4, the carrier combination determined by the received configuration signaling includes carrier 1 and carrier 3, corresponding to a number of carriers of 2. The carriers to be monitored by the first node during the time period from T1 to T2 can be determined based on a comparison of the number of carriers corresponding to the configuration information of the carrier combination determined by the configuration signaling received during the time period from T1 to T2 and the number of carriers supported for monitoring by the first node. The carriers to be monitored by the first node during the time period from T2 to T3 can be determined based on a comparison of the number of carriers corresponding to the configuration information of the carrier combination determined by the configuration signaling received during the time period from T2 to T3 and the number of carriers supported for monitoring by the first node. The determination of the carriers to be monitored by the first node during the time period from T3 to T4 and other time periods also adopts a similar method as described above, which will not be repeated here.

[0057] As another example, continuing to refer to Figure 3, the number of carriers corresponding to all carriers configured on the network side is 3, namely carrier 1, carrier 2, and carrier 3. The carriers corresponding to the configuration information of the carrier combination determined by the configuration signaling are also carrier 1, carrier 2, and carrier 3. The number of carriers corresponding to the configuration information of the carrier combination determined by the configuration signaling is equal to the number of carriers corresponding to all carriers configured on the network side. At this time, the carrier to be monitored by the first node can be determined based on a comparison between the number of carriers supported for monitoring by the first node and the number of carriers corresponding to all carriers configured on the network side.

[0058] In the case that the number of carriers supported for monitoring by the first node is unknown, the carriers to be monitored by the first node may be determined by combining the methods of the embodiments.

[0059] It is understandable that in some technologies, when the carrier combination is semi-statically configured, the carrier to be monitored by the first node is determined by comparing the number of carriers supported for monitoring by the first node with the number of carriers included in the carrier combination semi-statically configured on the network side. When the number of carriers supported for monitoring by the first node is equal to or not equal to the number of carriers included in the carrier combination semi-statically configured on the network side, the standard clearly stipulates how the first node selects the carrier to be monitored. Since the present disclosure dynamically configures the carrier combination, there will be a large error in determining the carrier to be monitored by the first node through these technologies, and it will also generate large power consumption. Therefore, the present disclosure determines the carrier to be monitored by the first node based on the configuration information of the carrier combination determined by the configuration signaling, and compares the number of carriers supported for monitoring by the first node with the number of dynamically configured carriers, so as to achieve timely and accurate determination of the carrier to be monitored by the first node when the carrier combination is dynamically configured.

[0060] In some embodiments, the size of the HARQ codebook is determined based on the configuration information of the carrier combination.

[0061] In some embodiments, determining the HARQ codebook size based on the configuration information of the carrier combination includes at least one of the following:

[0062] Determine the size of the HARQ codebook based on the number of carriers corresponding to the configuration information of the carrier combination;

[0063] Determining a size of the HARQ codebook based on the number of carriers corresponding to the configuration information of the carrier combination determined by the configuration signaling received within a preset time period;

[0064] When the number of carriers corresponding to the configuration information of the carrier combination determined by the configuration signaling is equal to the number of carriers corresponding to all carriers configured on the network side, the size of the HARQ codebook is determined based on the number of carriers corresponding to all carriers configured on the network side.

[0065] It is understandable that in some technologies, the hybrid automatic repeat request (HARQ) codebook that indicates whether the channel transmission is correct includes three types, type 1, type 2, and type 3. The codebook size of HARQ codebook type 1 and type 3 is determined based on the number of carriers included in the CA combination (carrier combination) semi-statically configured on the network side. Since the present disclosure dynamically configures the carrier combination, determining the size of the HARQ codebook through these technologies will result in a large error and will also generate large power consumption. Therefore, the present disclosure determines the size of the HARQ codebook of the first node based on the configuration information of the carrier combination determined by the configuration signaling, and can determine the size of the HARQ codebook in a timely and accurate manner.

[0066] In some embodiments, the configuration information of the carrier combination includes frequency domain resource allocation information.

[0067] In some embodiments, a method for determining the frequency domain resource allocation information includes at least one of the following:

[0068] Configure frequency domain resource allocation information based on the frequency domain resources formed by combining all secondary carriers in the carrier combination;

[0069] Frequency domain resource allocation information is configured based on the frequency domain resources formed by combining all secondary carriers in the carrier combination pattern.

[0070] In some embodiments, the carrier combination pattern is configured according to semi-static signaling.

[0071] Exemplarily, a scheduling method that combines single carrier and multi-carrier collaboration. Multiple secondary carriers are configured into a super single carrier, and the frequency domain resources are the sum of the frequency domain resources of multiple secondary carriers within the super single carrier. Scheduling information, namely frequency domain resource allocation (FDRA), is sent by the primary carrier through dynamic DCI indication. As shown in Figure 3, carrier 2 and carrier 3 form a super single carrier, and the frequency domain resources are the sum of all frequency domains of carrier 2 and carrier 3. Scheduling information is sent by carrier 1.

[0072] Exemplary scheduling methods utilize a single carrier and multiple carrier combination patterns. Semi-static signaling configures a carrier combination pattern, where the frequency domain resources are the sum of the frequency domain resources of all carriers within the carrier combination pattern. The carrier combination pattern can be divided according to the time domain, corresponding to N time slots or N subframes within a cycle. N is an integer greater than 0. Furthermore, scheduling information, including FDRA, is sent by the primary carrier via dynamic DCI indications.

[0073] It is understandable that the configuration information of the carrier combination determined by the configuration signaling can be determined by combining different methods in the above embodiments, or by selecting methods in different embodiments at different times.

[0074] In some embodiments, the configuration signaling is further used to determine a physical downlink control channel (PDCCH) to be monitored.

[0075] In some embodiments, the PDCCH to be monitored is determined by at least one of the following methods:

[0076] Configuration signaling is used to indicate the PDCCHs to be monitored on all secondary carriers in the carrier combination;

[0077] The configuration signaling is used to indicate the PDCCHs to be monitored on the secondary carriers within all activation time periods in the carrier combination.

[0078] In some embodiments, when the configuration signaling is used to indicate the PDCCHs to be monitored on the secondary carriers in all activation time periods in the carrier combination, the first node may only monitor the PDCCH corresponding to the start time of the secondary carrier activation state.

[0079] In some embodiments, the configuration signaling is carried on a primary carrier in the carrier combination.

[0080] When the resources occupied by the PDCCH configured on the secondary carrier are not used to send the PDCCH, they can be used to send a physical downlink shared channel (PDSCH) or other downlink channels or downlink signals, thereby improving resource utilization efficiency.

[0081] As mobile communication technology develops, it is likely that all terminals will support CA technology. However, since multiple carriers operate simultaneously, terminal power consumption is high. By reducing the monitoring frequency of PDCCH, terminal power consumption can be reduced.

[0082] In some embodiments, the configuration information of the carrier combination determined by the configuration signaling is discontinuous reception (DRX) configuration information.

[0083] In some embodiments, the configuration signaling includes Radio Resource Control (RRC) signaling.

[0084] In some embodiments, the different DRX configuration information of different carriers in the carrier combination determined by the configuration signaling includes at least one of the following:

[0085] The on-duration time corresponding to the auxiliary carrier in the carrier combination is aligned with the on-duration time corresponding to the main carrier in the time domain;

[0086] The number of carriers in the carrier combination that are simultaneously in the on-duration period does not exceed a preset number.

[0087] In some embodiments, the carriers in the carrier combination are active during the on-duration. If no PDCCH is received during this period, the terminal will enter the DRX sleep state until the next "on-duration" begins.

[0088] For example, Figure 4 provides a schematic diagram of a carrier combination, which includes carrier 1, carrier 2, and carrier 3. Carrier 1, carrier 2, and carrier 3 correspond to different DRX patterns, that is, the states of carrier 1, carrier 2, and carrier 3 may be different at different times. Assuming that carrier 1 is the primary carrier, carrier 2 and carrier 3 are auxiliary carriers, the on-duration corresponding to carrier 2 and carrier 3 is aligned with the on-duration corresponding to carrier 1 in the time domain. And only the terminal is active during the on-duration and will monitor the PDCCH. If no PDCCH is received during the on-duration, the terminal will enter the DRX sleep state.

[0089] As another example, Figure 5 provides a schematic diagram of a carrier combination, which includes carrier 1, carrier 2 and carrier 3, carrier 1, carrier 2 and carrier 3 respectively corresponding to different DRX patterns, and the number of carriers in the carrier combination that are simultaneously in the on-duration period does not exceed 2.

[0090] As mobile communication technology continues to develop, it is likely that all terminals will support CA technology. However, since multiple carriers operate simultaneously, terminal power consumption is high. By designing DRX patterns, terminal power consumption can be reduced.

[0091] In some embodiments, as shown in Figure 6, the network side has a total of four carriers. Carrier 1 and carrier 2 are time division duplexing (TDD) carriers with large frequency domain bandwidth, while carrier 3 and carrier 4 are frequency division duplexing (FDD) carriers with small frequency domain bandwidth. TDD carriers are used to transmit channel type 1, and FDD carriers are used to transmit channel type 2. Channel type 1 can be PDCCH, physical uplink control channel (PUCCH), and channels other than traffic channels; channel type 2 can be PDSCH and physical uplink shared channel (PUSCH). The network side can semi-statically divide the CA combination according to channel type.

[0092] S102: The first node and the second node perform multi-carrier communication based on configuration information of the carrier combination.

[0093] Based on this, based on different channel states, the second node can send different configuration signaling to the first node in a timely manner, so that the first node and the second node can perform multi-carrier communication based on the configuration information of different carrier combinations determined by different configuration signaling, thereby realizing dynamic configuration of carrier combinations to match the actual channel state and improving communication efficiency.

[0094] Currently, in CA, the UE transmit power is defined as the sum of the transmit power of each cell and the total carrier combination. When dynamic carrier combination is introduced, the method for defining the terminal's transmit power can be at least one of the following:

[0095] Method 1: Transmit power of each carrier.

[0096] Method 2: Transmit power of each carrier combination, that is, defining / reporting transmit power according to the carrier combination mentioned in the above embodiment.

[0097] In some embodiments, current mobile communication system standards define the maximum number of carriers for combinations of consecutive or non-consecutive carriers within the same carrier frequency, as well as the maximum number of carriers for combinations of carriers within different carrier frequencies. In future mobile communication systems, the capabilities corresponding to multiple carriers may be at least one of the following:

[0098] Method 1: Maximum number of carriers: Regardless of the number of carriers within the same carrier frequency or within different carrier frequencies, a unified maximum number of carriers is defined.

[0099] Method 2: Maximum number of carriers between different carrier frequencies. That is, only a single carrier is supported within the same carrier frequency, or the number of carriers within the same carrier frequency is not limited, and only the maximum number of carriers between different carrier frequencies is defined.

[0100] Furthermore, multiple carriers within the same carrier frequency can be combined into one carrier.

[0101] Method 3: Define the maximum number of carriers within the same carrier frequency and the maximum number of carriers between different carrier frequencies.

[0102] Furthermore, the maximum number of carriers within the same carrier frequency is defined only for a portion of the bandwidth, for example, only for a new frequency band or a terahertz frequency band, or only for an existing frequency band.

[0103] The above mainly introduces the solutions of the embodiments of the present disclosure from the perspective of methods. The following also shows a carrier configuration device, which is used to execute the carrier configuration method in any of the above embodiments and possible implementations thereof.

[0104] It is understandable that, in order to implement the carrier configuration method, the carrier configuration device includes hardware structures and / or software modules corresponding to the execution of various functions; those skilled in the art should easily realize that, in combination with the algorithm steps of the various examples described in the embodiments of the present disclosure, the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in hardware or in a computer software-driven hardware manner depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the present disclosure.

[0105] The embodiments of the present disclosure can divide the carrier configuration device into functional modules according to the above-mentioned method embodiments. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one functional module. The above-mentioned integrated modules can be implemented in the form of hardware or software. It should be noted that the division of modules in the embodiments of the present disclosure is illustrative and is only a logical functional division. In actual implementation, other division methods may be used. The following description uses the example of dividing each functional module according to each function.

[0106] 7 is a schematic diagram of the structure of a carrier configuration device provided by an embodiment of the present disclosure, which is applied to a first node. The carrier configuration device 700 includes: a communication module 701 and a processing module 702.

[0107] The communication module 701 is configured to receive configuration signaling, where the configuration signaling is used to determine configuration information of a carrier combination;

[0108] The communication module 701 is further configured to perform multi-carrier communication based on the configuration information of the carrier combination.

[0109] In some embodiments, the configuration signaling includes downlink control information DCI.

[0110] In some embodiments, the configuration signaling includes a bitmap, the bitmap includes multiple indication bits, each indication bit corresponds to a carrier, and each indication bit is used to indicate whether the carrier corresponding to the indication bit belongs to a carrier combination.
