Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0002] In a communication network, each cell has a frequency band, which corresponds to the uplink and downlink operating frequency bands for sending and receiving of base stations and terminals. Since spectrum resources are relatively precious, when designing the band, for example, as shown in the frequency band range defined in Table 5.2-1 of 3GPP TS38.104, the frequency band design of some duplex modes for supplementary uplink (SUL) or supplementary downlink (SDL) overlaps with time division duplexing (TDD) or frequency division duplexing (FDD).

[0003] The current networking requires complete independent bands. The establishment of various cells requires the corresponding band planning. For example, the establishment of SDL cells requires an independent SDL band, and the establishment of SUL cells requires an independent SUL band. However, spectrum planning is relatively scarce. If independent spectrum is used to establish SUL cells and SDL cells, it will cause relatively large interference to the current spectrum planning, making it difficult to open SUL cells and SDL cells, which is not conducive to improving uplink and downlink transmission capabilities. Summary of the invention

[0004] The embodiments of the present application provide a communication method and device, which can flexibly configure auxiliary frequency bands, thereby facilitating improving uplink and downlink transmission capabilities.

[0005] In a first aspect, an embodiment of the present application provides a communication method, the method comprising:

[0006] generating a cell measurement result, where the cell measurement result includes a measurement result of at least one first cell, where a frequency band of the first cell matches a target frequency band;

[0007] Sending the cell measurement result to the first communication device;

[0008] Configuration information is received from the first communication device, where the configuration information is used to indicate a frequency band of a second cell as an auxiliary frequency band, where the second cell is a first cell in the at least one first cell whose measurement result satisfies a condition.

[0009] The method may be applied to a second communication device. Optionally, the first communication device may be a network device, or a device in a network device (e.g., a chip, or a chip system, or a circuit). The second communication device may be a terminal device, or a device in a terminal device (e.g., a chip, or a chip system, or a circuit).

[0010] In the above embodiment, the second communication device can obtain the measurement result of at least one first cell through cell measurement, the frequency band of the first cell matches the target frequency band, and the target frequency band can be understood as the frequency band that needs to be supplemented. The second communication device sends the measurement result to the first communication device, and the first communication device can select a second cell that meets the conditions from the first cell based on the measurement result, and send configuration information to the second communication device. The configuration information is used to indicate the frequency band of the second cell as an auxiliary frequency band, so that the second communication device can use the auxiliary frequency band for data transmission.

[0011] Through the above embodiments, frequency bands that can be used as auxiliary frequency bands (such as auxiliary uplink SUL or auxiliary downlink SDL) can be flexibly sensed from existing cells (such as frequency division duplex FDD cells or time division duplex TDD cells), so there is no need to additionally plan independent SUL frequency bands or SDL frequency bands. Cells can be flexibly networked, which is conducive to opening up auxiliary uplink and auxiliary downlink capabilities over a large range, thereby facilitating the improvement of uplink and downlink data transmission capabilities, increasing uplink and downlink traffic, and improving system throughput and far-point coverage capabilities. In addition, the embodiments of the present application obtain available auxiliary frequency bands through cell measurements, which can be regarded as a solution for dynamically configuring auxiliary frequency bands, which has high flexibility. Compared with statically adding auxiliary frequency bands, this solution can efficiently share spectrum.

[0012] In a possible implementation manner of the first aspect, the frequency band of the first cell includes: an uplink frequency band and / or a downlink frequency band of the first cell.

[0013] Through the above implementation, the frequency band that can be used as SUL and / or SDL can be sensed from the first cell, so as to improve the uplink and / or downlink transmission capacity.

[0014] In a possible implementation manner of the first aspect, the first cell is a frequency division duplex FDD cell or a time division duplex TDD cell.

[0015] Through the above implementation, frequency bands that can be used as SUL and / or SDL can be flexibly obtained from existing FDD cells or TDD cells without additionally planning independent SUL frequency bands and / or SDL frequency bands, and cells can be flexibly networked.

[0016] In a possible implementation manner of the first aspect, the matching of the frequency band of the first cell with the target frequency band includes: the frequency band of the first cell is the same as the target frequency band, or the frequency band of the first cell is included in the target frequency band.

[0017] Through the above implementation manner, the frequency band of the first cell is the same as the target frequency band or is included in the target frequency band, so that the frequency band of the first cell can meet the frequency band requirement as an auxiliary frequency band.

[0018] In a possible implementation manner of the first aspect, before generating the cell measurement result, the method further includes:

[0019] Sending capability information to the first communication device, where the capability information is used to indicate a frequency band supported by the second communication device;

[0020] Receive measurement indication information from the first communication device, where the measurement indication information includes the target frequency band, and the target frequency band is at least one frequency band supported by the second communication device.

[0021] Through the above implementation, the second communication device can report capability information to the first communication device, and the first communication device can determine whether the second communication device has the ability to support the auxiliary frequency band based on the capability information. If it is determined that the second communication device has the ability to support the auxiliary frequency band, measurement indication information can be sent to the second communication device to instruct the second communication device to measure the corresponding frequency band so as to obtain an auxiliary frequency band that can be suitable for the second communication device.

[0022] In a possible implementation manner of the first aspect, the measurement result includes signal quality, the condition includes a quality threshold, and the signal quality of the second cell is higher than the quality threshold.

[0023] Through the above implementation, the second cell can be selected according to the signal quality. Specifically, the first cell whose signal quality is higher than the quality threshold can be used as the second cell. In this way, an auxiliary frequency band with better signal quality can be obtained, which is conducive to improving the auxiliary transmission capability.

[0024] In a possible implementation manner of the first aspect, in the at least one first cell, the signal quality of the second cell is the highest.

[0025] Through the above implementation, the second cell can be selected according to the signal quality. Specifically, the first cell with the highest signal quality and above the quality threshold can be used as the second cell. In this way, an auxiliary frequency band with better signal quality can be obtained, which is conducive to improving the auxiliary transmission capability.

[0081] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0082] In this application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of the words "exemplary" or "for example" is intended to present the related concepts in a concrete way.

[0083] The "first", "second", etc. mentioned in the embodiments of the present application do not limit the quantity and execution order, and the "first", "second", etc. do not limit them to be necessarily different. In addition, the terms "include", "comprise", "include", and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products, or devices.

[0084] The "embodiment" mentioned in this article means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It can be explicitly and implicitly understood by those skilled in the art that in the various embodiments of the present application, if there is no special explanation and logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0085] It should be understood that in the present application, "at least one" means one or more, and "plurality" means two or more. "And / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0086] In the description of this application, "indication" may include direct indication and indirect indication, and may also include explicit indication and implicit indication. The information indicated by a certain information is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated. For example, the information to be indicated may be directly indicated, such as indicating the information to be indicated itself or the index of the information to be indicated. For another example, the information to be indicated may be indirectly indicated by indicating other information, and there is a correlation between the indicated other information and the information to be indicated. For another example, only a part of the information to be indicated may be indicated, while the other parts of the information to be indicated are known or agreed in advance. In addition, the indication of specific information may be achieved by means of the arrangement order of each information agreed in advance (such as specified in the protocol), thereby reducing the indication overhead to a certain extent.

[0087] In a communication network, each cell has a frequency band, which corresponds to the uplink and downlink operating frequency bands for sending and receiving of base stations and terminals. Since spectrum resources are relatively precious, when designing the band, for example, as shown in the frequency band range defined in Table 5.2-1 of 3GPP TS38.104, the frequency band design of some duplex modes for supplementary uplink (SUL) or supplementary downlink (SDL) overlaps with time division duplexing (TDD) or frequency division duplexing (FDD). For example, as shown in the frequency band range defined in Table 5.2-1 of 3GPP TS38.104, Band n80 is a SUL band, but it overlaps with the uplink frequency band of Band n3 FDD, both are 1710MHz-1785MHz; Band n95 is a SUL band, but it overlaps with the uplink frequency band of Band n34 TDD, both are 2010MHz-2025MHz; Band n75 is an SDL band, but it overlaps with the downlink frequency band of Band n92 FDD, both are 1432MHz-1517MHz; Band n76 is an SDL band, but it overlaps with the downlink frequency band of Band n51 TDD, both are 1427MHz-1432MHz.

[0088] The current networking requires complete independent bands. The establishment of various cells requires the corresponding band planning. For example, the establishment of SDL cells requires an independent SDL band, and the establishment of SUL cells requires an independent SUL band. However, spectrum planning is relatively scarce. If independent spectrum is used to establish SUL cells and SDL cells, it will cause relatively large interference to the current spectrum planning, making it difficult to open SUL cells and SDL cells, which is not conducive to improving uplink and downlink transmission capabilities.

[0089] In order to solve the above problems, the embodiments of the present application provide a communication method and device, which can flexibly configure auxiliary frequency bands, thereby improving uplink and downlink transmission capabilities.

[0090] The technical solutions of the embodiments of the present application can be applied to various communication systems, for example: global system for mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, general packet radio service (GPRS), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, universal mobile telecommunications system (UMTS) system, enhanced data rate for GSM evolution (EDGE) system, and worldwide interoperability for microwave access (WiMAX) system. The technical solutions of the embodiments of the present application can also be applied to other communication systems, such as public land mobile network (PLMN) system, advanced long term evolution (LTEadvanced, LTE-A) system, fifth generation (5G) system, new radio (NR) system, machine to machine communication (machine to machine, M2M) system, or other communication systems evolved in the future, etc., which are not limited by the embodiments of the present application.

[0091] See also Figure 1 , Figure 1 Schematic diagram of a network architecture of a communication system provided in an embodiment of the present application. Figure 1 As shown, the network architecture includes a first communication device 101 and a second communication device 102. The first communication device 101 may be a network device, or a device in a network device (e.g., a chip, or a chip system, or a circuit). The second communication device 102 may be a terminal device, or a device in a terminal device (e.g., a chip, or a chip system, or a circuit).

[0092] Exemplarily, wireless communication can be performed between the first communication device 101 and the second communication device 102 by using air interface resources. Among them, the air interface resources can include at least one of time domain resources, frequency domain resources, code resources, and space resources.

[0093] The network devices involved in the embodiments of the present application can include, but are not limited to: base stations, next-generation base stations (gNBs), evolved Node Bs (eNBs), radio network controllers (RNCs), Node Bs (NBs), base station controllers (BSCs), base transceiver stations (BTSs), home evolved Node Bs (HeNBs, or home Node Bs, HNBs), baseband units (BBUs), servers, wearable devices, vehicle-mounted devices, access points (APs) in wireless fidelity (WIFI) systems, wireless relay nodes, wireless backhaul nodes, transmission points (TPs), or transmission and reception points (TRPs), etc. It can also be 5G, such as gNBs, TRPs, or TPs in a new radio (NR) system, one or a group of antenna panels of a base station in a 5G system, or it can also be a network node constituting a gNB or a TP, such as a baseband unit or a distributed unit (DU), etc. Among them, the base station can be a macro base station, a micro base station, a pico base station, a small station, a relay station, or a balloon station, etc. The base station can be a terrestrial base station or a non-terrestrial base station, such as a low earth orbit (LEO) / very low earth orbit (VLEO) satellite, an unmanned aerial vehicle (UAV), or other high attitude platform stations (HAPS), etc.

[0094] In some deployments, the gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some functions of the gNB, and the DU implements some functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, and implementing the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. The AAU implements some physical layer processing functions, RF processing, and related functions of active antennas. The information of the RRC layer is generated by the CU, and will eventually be encapsulated by the PHY layer of the DU to become the PHY layer information, or, it is converted from the PHY layer information. Therefore, in this architecture, high-level signaling such as RRC layer signaling can also be considered to be sent by the DU, or, sent by the DU+AAU. It is understandable that the network device may be a device including one or more of a CU node, a DU node, and an AAU node. In addition, the CU may be divided into a network device in an access network (radio access network, RAN), or the CU may be divided into a network device in a core network (core network, CN), which is not limited in the embodiments of the present application.

The device can be installed in the network device, such as a chip system. The chip system can be composed of a chip, or it can include a chip and other discrete devices.

The terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on the water surface (for example, on a ship); it can also be deployed in the air (for example, on an airplane, a balloon or a satellite). The terminal device can be a handheld device, a vehicle-mounted device, a wearable device or a computing device with a wireless communication function. Exemplarily, the terminal device can be a mobile phone, a tablet computer (pad) or a computer with a wireless transceiver function. The terminal device can also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control (such as a robot, etc.), a wireless terminal in the Internet of Vehicles (such as vehicle-mounted equipment, vehicle-wide equipment, vehicle-mounted modules, vehicles, etc.), a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, a wireless terminal in a smart home, and the like.

[0097] In an embodiment of the present application, the device for realizing the functions of the terminal device may be a terminal device, or a device that can support the terminal device to realize its functions. The device may be installed in the terminal device, such as a chip system. The chip system may be composed of a chip, or may include a chip and other discrete devices.

[0098] It should be understood that Figure 1 The network architecture shown is only an example, and the network architecture applicable to the embodiments of the present application is not limited to this.

Figures 2 to 4 For the corresponding embodiment) the second communication device may be Figure 2The second communication device 102 in the embodiment of the present application, the function performed by the second communication device in the embodiment of the present application can also be performed by a device (for example, a chip, or a chip system, or a circuit) in the second communication device. The embodiment of the present application is described here in a unified manner and will not be repeated later.

[0100] The following is an introduction to the communication method provided in the embodiments of the present application.

[0101] See also Figure 2 , Figure 2 It is a flow chart of a communication method provided in an embodiment of the present application. Figure 2 The illustrated embodiment takes the first communication device and the second communication device as the execution subjects of the interaction as an example to illustrate the method.

[0102] like Figure 2 As shown, the communication method may include but is not limited to the following steps S201 to S204.

[0103] S201: The second communication device generates a cell measurement result.

[0104] The cell measurement result includes a measurement result of at least one first cell, and a frequency band of the first cell matches a target frequency band.

[0105] The first cell may be understood as a cell that meets the measurement requirement, and the measurement requirement may include: the frequency band of the first cell matches the target frequency band. Among them, the target frequency band may be understood as a frequency band that needs to be supplemented. The frequency band of the first cell matches the target frequency band, which may be understood as the frequency band of the first cell meets the frequency band requirement as a supplementary frequency band (or auxiliary frequency band).

[0106] Specifically, after the second communication device accesses the serving cell, it can measure the surrounding cells, for example, the measurement can be but not limited to A5 measurement or A6 measurement, so as to generate corresponding cell measurement results. Exemplarily, the serving cell accessed by the second communication device can be a TDD cell or an FDD cell.

[0107] In a possible implementation manner, the target frequency band is at least one frequency band supported by the second communication device.

[0108] Before the second communication device generates the cell measurement result, the second communication device may send capability information to the first communication device, and correspondingly, the first communication device receives the capability information from the second communication device, wherein the capability information may indicate the frequency band supported by the second communication device.

[0109] After receiving the capability information from the second communication device, the first communication device may send measurement instruction information to the second communication device, and correspondingly, the second communication device receives the measurement instruction information from the first communication device. The measurement instruction information may include a target frequency band, and the target frequency band may be a frequency band determined by the first communication device according to a frequency band supported by the second communication device.

[0110] After receiving the measurement instruction information from the first communication device, the second communication device may perform measurement in a cell frequency band that matches the target frequency band, thereby generating a cell measurement result.

[0111] Through the above implementation, the second communication device can report capability information to the first communication device, and the first communication device can determine whether the second communication device has the ability to support the auxiliary frequency band based on the capability information. If it is determined that the second communication device has the ability to support the auxiliary frequency band, measurement indication information can be sent to the second communication device to instruct the second communication device to measure the corresponding frequency band so as to obtain an auxiliary frequency band that can be suitable for the second communication device.

[0112] In a possible implementation manner, the matching of the frequency band of the first cell with the target frequency band includes: the frequency band of the first cell is the same as the target frequency band, or the frequency band of the first cell is included in the target frequency band.

[0113] For example, assuming that the target frequency band is represented by (f1, f2) and the frequency band of the first cell is represented by (f3, f4), when f3=f1 and f4=f2, it means that the frequency band of the first cell is the same as the target frequency band; when f1<f3<f4<f2, it means that the frequency band of the first cell is included in the target frequency band. In this way, the frequency band of the first cell can meet the frequency band requirement as an auxiliary frequency band.

[0114] In a possible implementation, the frequency band of the first cell may be an uplink frequency band of the first cell. Accordingly, the target frequency band may be an uplink frequency band that needs to be supplemented, and the uplink frequency band of the first cell matches the uplink frequency band that needs to be supplemented. In this way, a frequency band that can be used as SUL can be sensed from the first cell to improve uplink transmission capability.

[0115] In another possible implementation, the frequency band of the first cell may be a downlink frequency band of the first cell. Accordingly, the target frequency band may be a downlink frequency band that needs to be supplemented, and the downlink frequency band of the first cell matches the downlink frequency band that needs to be supplemented. In this way, a frequency band that can be used as SDL can be sensed from the first cell to improve downlink transmission capability.

[0116] In another possible implementation, the frequency band of the first cell may include an uplink frequency band and a downlink frequency band of the first cell. Accordingly, the target frequency band may include an uplink frequency band and a downlink frequency band that need to be supplemented, the uplink frequency band of the first cell matches the uplink frequency band that needs to be supplemented, and the downlink frequency band of the first cell matches the downlink frequency band that needs to be supplemented. In this way, a frequency band that can be used as SUL and a frequency band that can be used as SDL can be sensed from the first cell to improve the uplink transmission capacity and the downlink transmission capacity.

[0117] It should be noted that the frequency bands that can be used as SUL and the frequency bands that can be used as SDL can come from different first cells. For example, a frequency band that can be used as SUL is extracted from one first cell (recorded as uplink frequency band 1), and a frequency band that can be used as SDL is extracted from another first cell (recorded as downlink frequency band 2). The uplink frequency band 1 and the downlink frequency band 2 can be combined into a new cell (for example, an FDD cell).

[0118] In a possible implementation, the first cell is an FDD cell or a TDD cell. In this way, a frequency band that can be used as SUL and / or SDL can be flexibly obtained from an existing FDD cell or TDD cell without additionally planning an independent SUL frequency band and / or SDL frequency band, and the cell can be flexibly networked. It should be understood that the uplink frequency band and the downlink frequency band of TDD are the same, and the frequency band used as SUL and / or SDL can be obtained by extracting part of the time slot.

[0119] S202: The second communication device sends a cell measurement result to the first communication device, and correspondingly, the first communication device receives the cell measurement result from the second communication device.

[0120] Specifically, after obtaining the cell measurement result through cell measurement, the second communication device may report the cell measurement result to the first communication device. After receiving the cell measurement result reported by the second communication device, the first communication device may select the auxiliary cell based on the cell measurement result and then determine the auxiliary frequency band.

[0121] S203: The first communication device determines a second cell according to the cell measurement result.

[0122] The second cell is a first cell whose measurement result satisfies the condition among at least one first cell.

[0123] The second cell can be understood as a cell that can be used as an auxiliary cell of the second communication device. The frequency band of the second cell meets the frequency band requirement as an auxiliary frequency band. In addition, the measurement result of the second cell meets the corresponding condition. The condition can be preconfigured by the first communication device or predefined in the protocol.

[0124] Specifically, after receiving the cell measurement result, the first communication device may determine whether the measurement result of each first cell meets the condition. If the measurement result of a first cell meets the condition, the first cell may be determined as the second cell.

[0125] In a possible implementation, the measurement result includes signal quality, the condition includes a quality threshold, and the measurement result of the second cell satisfies the condition specifically by: the signal quality of the second cell is higher than the quality threshold.

[0126] Specifically, the first communication device may determine whether the signal quality of each first cell is higher than a quality threshold, and then select one of the first cells whose signal quality is higher than the quality threshold as the second cell.

[0127] Optionally, the signal quality may be represented by reference signal receiving power (RSRP), and accordingly, the quality threshold may be an RSRP threshold, and the RSRP of the second cell is higher than the RSRP threshold.

[0128] Through the above implementation, the second cell can be selected according to the signal quality. Specifically, the first cell with a signal quality higher than the quality threshold can be used as the second cell. In this way, an auxiliary frequency band with better signal quality can be obtained, which is conducive to improving the auxiliary transmission capability.

[0129] In another possible implementation, the measurement result includes signal quality, the condition includes a quality threshold, and the measurement result of the second cell satisfies the condition specifically that: the signal quality of the second cell is higher than the quality threshold, and the signal quality of the second cell is the highest among all first cells.

[0130] Specifically, the first communication device may determine whether the signal quality of each first cell is higher than a quality threshold, and then select the first cell with the highest signal quality as the second cell from among the first cells with signal quality higher than the quality threshold.

[0131] Optionally, the signal quality may be represented by reference signal receiving power (RSRP), and accordingly, the quality threshold may be an RSRP threshold, the RSRP of the second cell is higher than the RSRP threshold, and the RSRP of the second cell is the highest among all the first cells.

[0132] Through the above implementation, the second cell can be selected according to the signal quality. Specifically, the first cell with the highest signal quality and above the quality threshold can be used as the second cell. In this way, an auxiliary frequency band with better signal quality can be obtained, which is conducive to improving the auxiliary transmission capability.

[0133] It should be noted that the indicator used to determine whether the measurement result meets the condition is not limited to the above-mentioned signal quality. In other embodiments, other indicators (such as standard, bandwidth or idleness) can also be used to determine whether the measurement result meets the condition. Exemplarily, for each first cell, the first communication device can score the first cell in combination with the four indicators of signal quality, standard, bandwidth and idleness of the first cell, and then select the second cell from it according to the scores of each first cell. For example, for the indicator of signal quality, the higher the signal quality, the higher the score; for another example, for the indicator of standard, the score of the standard FDD is higher than the score of the standard TDD; for another example, for the indicator of bandwidth, the larger the bandwidth, the higher the score; for another example, for the indicator of idleness, the higher the idleness, the higher the score. The higher the score of the first cell, the more suitable it is for the first cell to be used as an auxiliary cell, and the first cell with the highest score can be used as the second cell. In this way, selecting the second cell in combination with multiple indicators is conducive to obtaining a more suitable auxiliary frequency band.

[0134] In a possible implementation, after the first communication device determines the second cell, it can also verify the second cell, and if the second cell passes the verification, it is finally determined that the second cell can be used as an auxiliary cell. This is conducive to ensuring that the frequency band of the second cell can be used as an auxiliary frequency band.

[0135] In one example, the first communication device verifies the second cell, which may be to check whether the second cell can be paired with the service cell of the second communication device. If the attributes of the second cell are the same as the attributes configured on the service cell side of the second communication device, it is considered that the second cell can be paired with the service cell of the second communication device. Among them, the attributes may include but are not limited to frequency band, frequency point, bandwidth, sub-carrier space (SCS), BWP0 starting position of the bandwidth part (BWP), BWP0 bandwidth, cyclic prefix (CP) length and CP type.

[0136] In another example, the first communication device verifies the second cell, which may be to check whether the second cell can be combined with the serving cell of the second communication device by a component carrier (CC). If the second cell can be combined with the serving cell of the second communication device by a CC, it is considered that the second cell can be paired with the serving cell of the second communication device.

[0137] S204, the first communication device sends configuration information to the second communication device, and correspondingly, the second communication device receives the configuration information from the first communication device.

[0138] The configuration information is used to indicate that the frequency band of the second cell is used as the auxiliary frequency band.

[0139] Specifically, after determining the second cell, the first communication device may send configuration information to the second communication device to configure the frequency band of the second cell as the auxiliary frequency band. After receiving the configuration information from the first communication device, the second communication device may use the auxiliary frequency band configured therein for data transmission.

[0140] Optionally, the first communication device may send configuration information to the second communication device via radio resource control (RRC) signaling. For example, the first communication device may carry the configuration information in a reconfiguration (recfg) element of the RRC signaling and send it to the second communication device. After the second communication device receives the RRC signaling, it may perform data transmission on the auxiliary frequency band configured in the RRC signaling.

[0141] In the above embodiment, the second communication device can obtain the measurement result of at least one first cell through cell measurement, the frequency band of the first cell matches the target frequency band, and the target frequency band can be understood as the frequency band that needs to be supplemented. The second communication device sends the measurement result to the first communication device, and the first communication device can select a second cell that meets the conditions from the first cell based on the measurement result, and send configuration information to the second communication device. The configuration information is used to indicate the frequency band of the second cell as an auxiliary frequency band, so that the second communication device can use the auxiliary frequency band for data transmission.

[0142] Through the above embodiments, frequency bands that can be used as auxiliary frequency bands (such as auxiliary uplink SUL or auxiliary downlink SDL) can be flexibly sensed from existing cells (such as frequency division duplex FDD cells or time division duplex TDD cells), so there is no need to additionally plan independent SUL frequency bands or SDL frequency bands. Cells can be flexibly networked, which is conducive to opening up auxiliary uplink and auxiliary downlink capabilities over a large range, thereby facilitating the improvement of uplink and downlink data transmission capabilities, increasing uplink and downlink traffic, and improving system throughput and far-point coverage capabilities. In addition, the embodiments of the present application obtain available auxiliary frequency bands through cell measurements, which can be regarded as a solution for dynamically configuring auxiliary frequency bands, which has high flexibility. Compared with statically adding auxiliary frequency bands, this solution can efficiently share spectrum.

[0147] The first communication device may determine whether the second communication device supports uplink capability based on capability information reported by the second communication device. After determining that the second communication device supports uplink capability, the first communication device may determine an uplink frequency band that needs to be supplemented (referred to as a target SUL frequency band).

[0148] S303: The first communication device sends measurement instruction information to the second communication device, and correspondingly, the second communication device receives the measurement instruction information from the first communication device.

[0152] S306: The first communication device determines a SUL cell according to the cell measurement result.

[0153] Optionally, the first communication device selects an FDD cell with the highest downlink RSRP that is higher than the RSRP threshold from all measured FDD cells, and records it as the target FDD cell. An uplink frequency band that is the same as the target SUL frequency band is extracted from the target FDD cell as the SUL frequency band, thereby forming a SUL cell, which is uplink paired with the TDD cell where the second communication device is located.

[0154] S307, the first communication device sends configuration information to the second communication device, and correspondingly, the second communication device receives the configuration information from the first communication device.

For example, the second communication device can also access the FDD cell; for another example, the SUL cell can be configured by measuring the available uplink frequency band of TDD.

After determining that the second communication device supports the downlink capability, the first communication device can determine the downlink frequency band to be supplemented (denoted as the target SDL frequency band).

[0163] S403, the first communication device sends measurement indication information to the second communication device, and correspondingly, the second communication device receives the measurement indication information from the first communication device.

An uplink frequency band that is the same as the target SDL frequency band is extracted from the target FDD cell as the SDL frequency band, thereby forming an SDL cell, which is CC combined with the TDD cell where the second communication device is located.
