Technical Field

[0001] The present application relates to communication technology, and more particularly to a method and device for configuring a supplementary uplink (SUL). Background Art

[0002] With the development of wireless communication technology and the rapid growth of mobile user needs, wireless communication networks are facing the demand for large bandwidth and large capacity.

[0003] In order to improve the uplink transmission capacity, the fifth generation mobile communication technology (5th-Generation, 5G) introduces supplementary uplink (SUL). SUL can supplement uplink coverage. Terminal devices can perform uplink transmission through SUL, thereby improving the uplink transmission capacity and coverage capability of the wireless communication network.

[0004] However, how to reasonably utilize limited spectrum resources as SUL working frequency band resources to improve uplink transmission capacity has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The embodiments of the present application provide a method and apparatus for configuring a supplementary uplink (SUL) to increase uplink transmission capacity.

[0006] In a first aspect, an embodiment of the present application provides a method for configuring a secondary uplink SUL, which may include: an access network device determines multiple synchronization signal blocks SSB, wherein each of the multiple SSBs includes configuration information of a SUL. The access network device may broadcast multiple synchronization signal blocks SSB via a downlink.

[0007] In this implementation, multiple SULs are configured to the terminal device through multiple SSBs, so that the terminal device can use one of the SULs for uplink transmission. This implementation can configure multiple SULs, thereby improving the uplink transmission capacity and coverage of the TDD cell, FDD cell, or SDL cell. Different terminal devices can use different SULs for uplink transmission, thereby reasonably utilizing the available spectrum resources for uplink transmission and improving the uplink transmission performance of the communication system.

[0008] In one possible design, the time domain resources occupied by the above-mentioned multiple SSBs do not overlap with each other, or the frequency domain resources occupied by the above-mentioned multiple SSBs do not overlap with each other.

[0009] This implementation adopts TDM to send multiple SSBs, or sends multiple SSBs on different frequency domain resources of a carrier, and sends the configuration information of multiple SULs to the terminal devices within the coverage of the access network device, so that the terminal devices can use one of the SULs for uplink transmission based on the configuration information of the multiple SULs. Different terminal devices can use different SULs for uplink transmission, thereby improving the uplink transmission capacity and coverage capability.

[0010] In one possible design, each of the multiple SSBs includes downlink configuration information. The downlink configuration information included in the multiple SSBs may be different.

[0011] In this implementation, when supporting multiple operators, multiple operators can use the same DL, different operators can configure their own SUL, and the configuration information of the DL of different operators can be different. By sharing one DL among multiple operators, resource utilization can be improved.

[0012] In a possible design, the method may also include: the access network device determines whether to switch the SUL where the terminal device resides based on the capabilities of the terminal device, the link qualities of multiple SULs, and / or the resource utilization of multiple SULs. The SUL where the terminal device resides is one of the multiple SULs.

[0013] This implementation makes a switching decision based on the capabilities of the terminal device, the link quality of multiple SULs and / or the resource utilization of multiple SULs. When determining to switch the SUL where the terminal device resides, the SUL where the terminal device resides is switched to optimize the uplink transmission of the terminal device, thereby improving the uplink transmission capacity and coverage capability of the access network device.

[0014] In one possible design, the access network device determines whether to switch the SUL where the terminal device resides based on the capability of the terminal device, the link quality of multiple SULs and / or the resource utilization of multiple SULs, which may include: when the reference signal received power or the signal to interference plus noise ratio of the SUL where the terminal device resides is less than a first threshold, or the uplink interference is greater than a second threshold, or the uplink bit error rate is greater than a third threshold, or the resource utilization is greater than a fourth threshold, the access network device determines whether to switch the SUL where the terminal device resides based on the capability of the terminal device, the link quality of multiple SULs and / or the resource utilization of multiple SULs.

[0015] This implementation method can optimize the uplink transmission of terminal devices, thereby improving the uplink transmission capacity and coverage capability of access network equipment.

[0016] In one possible design, the multiple SULs include a first SUL and a second SUL. The first SUL is the SUL where the terminal device resides. The access network device determines whether to switch the SUL where the terminal device resides based on the capabilities of the terminal device, the link qualities of the multiple SULs, and / or the resource utilization of the multiple SULs, which may include: when the capabilities of the terminal device support the second SUL, and the link quality of the first SUL is lower than the link quality of the second SUL, and / or the resource utilization of the first SUL is greater than the resource utilization of the second SUL, determining to switch the SUL where the terminal device resides from the first SUL to the second SUL.

[0017] This implementation method can optimize the uplink transmission of terminal devices, thereby improving the uplink transmission capacity and coverage capability of access network equipment.

[0018] In a possible design, each SUL and downlink corresponds to a logical cell, and different SULs correspond to different logical cells.

[0019] In this implementation, each SUL and downlink corresponds to a logical cell, and the logical cell may be a cell obtained by logically dividing a TDD cell, an FDD cell, or an SDL cell. By dividing the logical cells and broadcasting multiple SSBs, the multiple SSBs are used to configure the SULs of multiple logical cells to configure the SULs of different logical cells, thereby optimizing uplink transmission and improving the uplink transmission capacity and coverage capability of the access network equipment.

[0020] In a second aspect, an embodiment of the present application provides a method for configuring a secondary uplink SUL, which may include: a terminal device receives multiple synchronization signal blocks SSB from an access network device via a downlink, each SSB in the multiple SSBs includes configuration information of a SUL. The terminal device resides in one SUL in the multiple SULs.

[0021] In this implementation, through multiple SSBs, the terminal device can obtain the configuration information of multiple SULs, and the terminal device can use one of the SULs for uplink transmission, thereby rationally utilizing the available spectrum resources for uplink transmission and improving the uplink transmission performance of the communication system.

[0022] In one possible design, the time domain resources occupied by multiple SSBs do not overlap with each other, or the frequency domain resources occupied by multiple SSBs do not overlap with each other.

[0027] In this implementation, the access network device determines whether to switch the SUL where the terminal device resides based on the capability of the terminal device, the link quality of multiple SULs and / or the resource utilization of multiple SULs. When it is determined to switch the SUL where the terminal device resides, the access network device sends a first message to the terminal device, and the first message is used to reconfigure the SUL where the terminal device resides, thereby optimizing the uplink transmission of the terminal device and improving the uplink transmission capacity and coverage capability of the access network device by switching the SUL where the terminal device resides.

For example, the communication system may include any number of access network devices such as 2, 3, 6, etc., and the communication system may include any number of terminal devices such as 2, 3, 6, etc.

[0064] The access network device 110 may be a transmission reception point (TRP), a base station, a relay station, a node or an access point, etc. The access network device 110 may be an access network device in a 5G communication system or an access network device in a future evolution network; it may also be a wearable device or a vehicle-mounted device, etc. In addition, it may also be: a base transceiver station (BTS) in a global system for mobile communication (GSM) or a code division multiple access (CDMA) network, or a NB (NodeB) in a wideband code division multiple access (WCDMA), or an eNB or eNodeB (evolutionalNodeB) in a long term evolution (LTE).

The access network device 110 may also adopt an architecture in which a centralized unit (CU) and a distributed unit (DU) are separated. The division of the CU and the DU may be divided according to the protocol stack.

The embodiments of the present application do not limit the application scenarios of the access network equipment and terminal equipment.

[0067] Figure 1 The communication system shown supports a supplementary uplink (SUL) scenario. FIG. 2A to FIG. 2C They are schematic diagrams of a SUL scenario provided in an embodiment of the present application. FIG. 2A to FIG. 2C As shown, the access network device 110 can provide a downlink (DL) and multiple uplinks (UL) to the terminal device 120.

[0068] In a possible application scenario, the access network device 110 may provide a DL and at least three ULs to the terminal device 120, where the at least three ULs may include a normal uplink (NUL) and at least two supplementary uplinks (SULs). The NUL and DL are transmitted in a time division duplex (TDD) or frequency division duplex (FDD) manner. Figure 2A As shown, the three ULs may be as follows Figure 2ANUL, SUL1 and SUL2 shown.

[0069] In another possible application scenario, refer to Figure 2B As shown, the access network device 110 can provide a DL and two ULs to the terminal device 120, and the two ULs can include a normal uplink (NUL) and a supplementary uplink (SUL). The NUL and DL are transmitted in an FDD manner. The two ULs can be as follows Figure 2B NUL and SUL1 shown.

[0070] In another application scenario, the access network device 110 may provide one DL and at least two ULs to the terminal device 120. The one DL may be a supplementary downlink (SDL), and the at least two ULs may be at least two SULs. Figure 2C As shown, the two SULs may be SUL 1 and SUL 2. Optionally, unlike the above NUL and DL using FDD for transmission, the SDL and SUL in this application scenario may not use symmetrical frequency band resources, for example, the SUL uses the uplink frequency band resources of FDD frequency band 1, and the SDL may use the downlink frequency band resources of FDD frequency band 2.

[0071] The access network device 110 provides a NUL and a SUL to the terminal device 120 (eg Figure 2B Taking SUL 1) as an example, the access network device 110 broadcasts a synchronization signal block (SSB) through DL, and the SSB may include the configuration information of NUL and the configuration information of SUL. The terminal device 120 can use NUL or SUL for uplink transmission according to the configuration information of NUL and SUL. The access network device configures SUL to improve the uplink transmission capacity and coverage capability.

[0072] For the access network equipment that provides NUL and DL using TDD working mode, the method for configuring SUL provided in the embodiment of the present application can configure multiple SULs for the terminal equipment in the TDD cell, so that the terminal equipment can use one of the SULs for uplink transmission. Different from configuring a single SUL in a TDD cell, the embodiment of the present application can configure multiple SULs in a TDD cell, and different terminal equipment in the TDD cell can use different SULs for uplink transmission, thereby improving the uplink transmission capacity and coverage capability of the TDD cell. The access network equipment can reasonably use the available spectrum resources for uplink transmission and improve the uplink transmission performance of the communication system. The TDD cell of this embodiment is a physical cell that adopts the TDD working mode. The TDD cell can be divided into multiple logical cells, one SUL and NUL in the above multiple SULs can correspond to one logical cell, and different SULs in the multiple SULs can correspond to different logical cells.

[0073] For the access network equipment that adopts the FDD working mode for the provided NUL and DL, the method for configuring SUL provided in the embodiment of the present application can configure one or more SULs to the terminal equipment in the FDD cell, so that the terminal equipment can use one of the SULs for uplink transmission. Unlike configuring one uplink for an FDD cell, the embodiment of the present application can realize that an FDD cell is configured with multiple uplinks, and the multiple uplinks include NUL and one or more SULs, thereby improving the uplink transmission capacity and coverage capability of the FDD cell. When configuring multiple SULs, different terminal devices in the FDD cell can use different SULs for uplink transmission, thereby reasonably utilizing the available spectrum resources for uplink transmission and improving the uplink transmission performance of the communication system. The FDD cell of this embodiment is a physical cell that adopts the FDD working mode. The FDD cell can be divided into multiple logical cells, one SUL and NUL in the above one or more SULs can correspond to one logical cell, and different SULs in the multiple SULs can correspond to different logical cells.

[0074] For access network equipment that provides SUL and SDL, the method for configuring SUL provided in the embodiment of the present application can configure multiple SULs for terminal devices in the SDL cell, so that the terminal device can use one of the SULs for uplink transmission. Unlike configuring one SUL for one SDL cell, the embodiment of the present application can configure multiple SULs for one SDL cell, thereby improving the uplink transmission capacity and coverage capability of the SDL cell. When configuring multiple SULs, different terminal devices in the SDL cell can use different SULs for uplink transmission, thereby rationally utilizing available spectrum resources for uplink transmission and improving the uplink transmission performance of the communication system. The SDL cell of this embodiment is a physical cell. The SDL cell can be divided into multiple logical cells, one SUL in the above multiple SULs can correspond to one logical cell, and different SULs in the multiple SULs can correspond to different logical cells.

[0075] Several specific embodiments are used below to explain the method for configuring SUL in the embodiment of the present application.

[0076] Figure 3 A flowchart of a method for configuring SUL provided in an embodiment of the present application is provided. This embodiment is illustrated by taking an access network device and a terminal device as an example. Figure 3 As shown, the method of this embodiment may include:

[0077] Step 301: The access network device determines multiple SSBs.

[0078] Each SSB of the multiple SSBs may include configuration information of one or more SULs, wherein the configuration information of one SUL is used to configure one SUL. The configuration information of one SUL may include information such as the frequency point and bandwidth of one SUL. This embodiment does not limit the frequency point indicated by the frequency point information of the SUL. For example, the frequency point indicated by the frequency point information of the SUL may be 1.8 GHz or 700 MHz.

[0079] In the case where each SSB in multiple SSBs includes configuration information of a SUL, the configuration information of the SULs of different SSBs is different. For example, the frequency information of the SULs of different SSBs is different. For example, multiple SSBs include SSB1 and SSB2, the configuration information of the SUL of SSB1 may include the frequency information of SUL 1, the configuration information of the SUL of SSB2 may include the frequency information of SUL 2, and the frequency information of SUL 1 is different from the frequency information of SUL 2. The frequencies indicated by different frequency information are different. The frequencies of the SULs configured for different SSBs may be different frequencies of the same bandwidth or different frequencies of different bandwidths. The frequencies of the SULs configured for different SSBs may be continuous different frequencies or discontinuous different frequencies.

[0080] In the case where each of the multiple SSBs includes configuration information of multiple SULs, the configuration information of the multiple SULs of the same SSB is different. For example, the frequency information of different SULs of the same SSB is different. For example, the SSB may include configuration information of SUL 1 and configuration information of SUL 2, and the frequency information of SUL 1 is different from the frequency information of SUL 2.

[0081] The multiple SSBs may be SSBs sent through the DL of a TDD cell of the access network device, or may be SSBs sent through the DL of an FDD cell of the access network device, or may be SSBs sent through the SDL of an SDL cell of the access network device. The TDD cell, FDD cell, and SDL cell are all physical cells. The TDD cell may be logically divided into multiple sub-cells, the FDD cell may be logically divided into multiple sub-cells, and the SDL cell may be logically divided into multiple sub-cells. Sub-cells may also be referred to as logical cells.

[0082] Optionally, each SSB in the multiple SSBs may further include configuration information of the NUL, and the configuration information of the NUL is used to configure the NUL. The configuration information of the NUL may include information such as the frequency and bandwidth of the NUL. For example, for Figure 2A and Figure 2B In the application scenario shown, the SSB sent by the access network device may also include NUL configuration information. The NUL configuration information of different SSBs may be the same or different.

[0083] Exemplarily, the access network device may determine multiple SSBs based on multiple available working frequency bands, so as to configure multiple SULs to the terminal device through multiple SSBs, so as to improve the uplink transmission capacity and coverage capability of the access network device. The multiple available working frequency bands may include the frequency band corresponding to the configuration information of the SUL of each SSB, and the frequency band corresponding to the configuration information of the SUL may be determined based on the frequency point information and bandwidth information included in the configuration information of the SUL.

[0084] Step 302: The access network device broadcasts multiple SSBs via DL.

[0085] Accordingly, the terminal device receives multiple SSBs via DL. The DL may be Figure 2A and Figure 2B DL in the application scenario shown can also be Figure 2CSDL in the application scenario shown. Multiple SULs configured by multiple SSBs correspond to the same DL. Taking SUL1 configured by SSB1 and SUL2 configured by SSB2 as an example for further explanation, SUL1 and SUL2 both correspond to DL, DL and SUL1 can form sub-cell 1, and DL and SUL2 can form sub-cell 2.

[0086] Optionally, when the above-mentioned SSB1 also includes the configuration information of NUL, and the above-mentioned SSB2 also includes the configuration information of NUL, DL, NUL and SUL1 can constitute sub-cell 1, and DL, NUL and SUL2 can constitute sub-cell 2. DL and NUL can adopt TDD or FDD working mode. The NUL of sub-cell 1 and sub-cell 2 can be the same or different. The difference between NUL of sub-cell 1 and sub-cell 2 can be that the frequency and / or bandwidth of NUL are different.

[0087] The access network device can broadcast and send multiple SSBs on the same DL in a staggered manner in the time domain or frequency domain. The following is an explanation of the first and second methods.

[0088] In method 1, the time domain resources occupied by the above-mentioned multiple SSBs are different. In other words, the access network equipment uses time division multiplexing (TDM) to send multiple SSBs.

[0089] It can be understood that the time domain resources occupied by each two SSBs in the above multiple SSBs are different, and different here can be understood as non-overlapping. For example, multiple SSBs include SSB1 and SSB3, and the time domain resources occupied by SSB1 and SSB3 are completely different. SSB1 occupies time domain resource 1, SSB3 occupies time domain resource 3, and time domain resource 1 and time domain resource 3 do not overlap.

[0090] In the second method, the frequency domain resources occupied by the above-mentioned multiple SSBs are different. In other words, the access network device can send multiple SSBs on different frequency domain resources of one carrier.

[0091] It can be understood that the frequency domain resources occupied by each two SSBs in the above multiple SSBs are different, and different here can be understood as non-overlapping. For example, multiple SSBs include SSB1 and SSB3, and the frequency domain resources occupied by SSB1 and SSB3 are completely different. SSB1 occupies frequency domain resource 1, SSB3 occupies frequency domain resource 3, and frequency domain resource 1 and frequency domain resource 3 do not overlap.

[0092] In Method 1 and Method 2, the multiple SSBs may be cell defining SSBs (Cell Defining SSBs). The cell defining SSB may be associated with a remaining minimum system information (RMSI), and the RMSI may carry cell identification information. The terminal device may determine a SUL service cell (also referred to as a sub-cell) based on the cell defining SSB. For example, when the SSB configures the SUL, the SSB is associated with the RMSI. The RMSI carries an NR cell global identifier (NCGI). The NCGI is used to identify the above-mentioned sub-cell, that is, the NCGI is used to identify the sub-cell corresponding to the SUL. The cell corresponding to the SUL may be a cell composed of SUL, NUL and DL, or it may be a cell composed of SUL and SDL. Different SULs may correspond to different NCGIs, that is, to different sub-cells.

[0093] Optionally, in some embodiments, in addition to broadcasting the above-mentioned multiple SSBs, i.e., multiple cell-defined SSBs, the access network device may also broadcast non-cell-defined SSBs, which have no associated RMSI and are used for radio resource management (RRM) measurements.

[0094] For example, Figure 4A The embodiment shown in the figure explains the above method 1, referring to Figure 4A As shown, the access network device sends SSB1 and SSB3 on different time domain resources, SSB1 is used to configure SUL1, and SSB3 is used to configure SUL2. SUL1 may correspond to sub-cell 1, and the NCGI of sub-cell 1 may be NCGI 5, and SUL2 may correspond to sub-cell 2, and the NCGI of sub-cell 2 may be NCGI 6. In some embodiments, the access network device may also send SSB2 and SSB4. Different from SSB1 and SSB3, SSB2 and SSB4 are non-cell-defined SSBs, and SSB2 and SSB4 may be used for RRM measurement.

[0095] by Figure 4B The embodiment shown in the figure explains the above method 2, referring to Figure 4BAs shown, the access network device sends SSB1 and SSB3 on different frequency domain resources of a carrier, SSB1 is used to configure SUL1, and SSB3 is used to configure SUL2. SUL1 may correspond to subcell 1, and the NCGI of subcell 1 may be equal to 5, and SUL2 may correspond to subcell 2, and the NCGI of subcell 2 may be equal to 6. In some embodiments, the access network device may also send SSB2 and SSB4. Unlike SSB1 and SSB3, SSB2 and SSB4 are non-cell-defined SSBs, which may be used for RRM measurement.

[0096] Optionally, each of the multiple SSBs in the above steps 301 and 302 may also include DL configuration information, and the DL configuration information contained in different SSBs may be the same or different. For example, when supporting multiple operators, multiple operators may use the same DL, but different operators may configure their own SULs, and the DL configuration information of different operators may be different. For example, the public land mobile network (PLMN) information in the DL configuration information of different operators is different.

[0097] Step 303: The terminal device resides in one of the multiple SULs according to the configuration information of the SULs of the multiple SSBs.

[0098] In one achievable manner, the terminal device may randomly reside in one of the multiple SULs according to the configuration information of the SULs of the multiple SSBs. For example, a random access is performed on one SUL, and then an uplink transmission is performed through the SUL.

[0099] Optionally, when the SSB also includes the configuration information of the NUL, the terminal device can randomly reside in the NUL or one of the multiple SULs according to the configuration information of the NUL and the configuration information of the multiple SULs. Figure 4A For example, SSB1 and SSB3 also include configuration information of NUL, and the configuration information of NUL includes information such as frequency and bandwidth of NUL. For example, the frequency indicated by the frequency information of NUL is 2.6 GHz, the frequency information of SUL1 included in SSB1 indicates that the frequency of SUL1 is 1.8 GHz, and the frequency information of SUL2 included in SSB3 indicates that the frequency of SUL2 is 700 MHz.

[0100] It should be noted that, for other terminal devices within the coverage of the FDD cell, TDD cell or SDL cell, random access may be performed in the same manner as step 303 .

[0101] In this embodiment, the access network device broadcasts multiple SSBs through DL, and configures multiple SULs to the terminal device through multiple SSBs, so that the terminal device can use one of the SULs for uplink transmission. Different from configuring a single SUL for a TDD cell, configuring an uplink for an FDD cell, or configuring a SUL for an SDL cell, the embodiment of the present application can configure multiple SULs, thereby improving the uplink transmission capacity and coverage capability of the TDD cell, FDD cell, or SDL cell. Different terminal devices can use different SULs for uplink transmission, thereby rationally utilizing the available spectrum resources for uplink transmission and improving the uplink transmission performance of the communication system.

[0102] After configuring multiple SULs, the access network device can also determine whether to switch the SUL where the terminal device resides based on the capabilities of the terminal device, the link quality of the multiple SULs and / or the resource utilization of the multiple SULs. When it is determined to switch the SUL where the terminal device resides, the terminal device is switched to other SULs to optimize the uplink transmission efficiency of the terminal device.

[0103] It should be noted that you can use Figure 3 The method of the illustrated embodiment configures multiple SULs, and other methods may also be used to configure multiple SULs. The embodiment of the present application does not specifically limit the switching judgment and the configuration method before switching between multiple SULs.

[0104] The capability of the terminal device is used to indicate the frequency or frequency range supported by the terminal device. The link quality of each SUL in multiple SULs can be represented by one or more of the reference signal received power (RSRP), signal to interference plus noise ratio (SINR), uplink interference (conversation system), or uplink bit error rate IBLER (calculated according to ACK / NACK). Among them, the higher the RSRP, the better the link quality, on the contrary, the lower the RSRP, the worse the link quality. The higher the SINR, the better the link quality, on the contrary, the lower the SINR, the worse the link quality. Among them, RSRP and SINR can be determined by measuring the sounding reference signal (SRS). The lower the uplink interference, the better the link quality, on the contrary, the greater the uplink interference, the worse the link quality. The lower the IBLER, the better the link quality, on the contrary, the greater the IBLER, the worse the link quality. The resource utilization rate of each SUL in the multiple SULs may represent the proportion of the RB resources of the SUL used by one or more terminal devices in the cell corresponding to the SUL in the available RB resources of the SUL. The higher the resource utilization rate, the higher the load of the SUL.

[0105] The following uses a specific embodiment to illustrate the implementation method of switching the SUL where the terminal device resides.

[0106] Figure 5 A flowchart of a method for configuring a switching of multiple SULs provided in an embodiment of the present application is provided. This embodiment is illustrated by taking an access network device and a terminal device as an example. Figure 5 As shown, the method of this embodiment may include:

[0107] Step 501: The access network device obtains the capability of the terminal device, the link quality of multiple SULs and / or the resource utilization of multiple SULs.

[0108] Step 502: The access network device determines whether to switch the SUL where the terminal device resides according to the capability of the terminal device, the link qualities of multiple SULs and / or the resource utilization rates of multiple SULs.

[0109] The SUL where the terminal device resides is one of multiple SULs.

[0110] The embodiments of the present application can be Figure 3 The method of the embodiment shown configures multiple SULs, and other methods may be used to configure multiple SULs, and then a switching judgment is made through steps 501 and 502. The explanation of the capabilities, link quality and resource utilization of the terminal device can be found in the above explanations, which will not be repeated here.

[0111] Optionally, before executing step 501, the switching judgment can also be triggered according to at least one of the coverage strength, load level or interference size of the SUL where the terminal device resides. For example, before executing step 501, the access network device determines whether the SUL where the terminal device resides satisfies one or more of the following: the RSRP or SINR of the SUL where the terminal device resides is less than the first threshold, or the uplink interference is greater than the second threshold, or the uplink bit error rate is greater than the third threshold, or the resource utilization rate is greater than the fourth threshold. When the RSRP or SINR of the SUL where the terminal device resides is less than the first threshold, or the uplink interference is greater than the second threshold, or the uplink bit error rate is greater than the third threshold, or the resource utilization rate is greater than the fourth threshold, the access network device executes steps 501 and 502.

[0112] In some embodiments, the plurality of SULs may include a first SUL and a second SUL, the first SUL being the SUL where the terminal device resides, and one implementation of the above step 502 is: when the capability of the terminal device supports the second SUL, and the link quality of the first SUL is lower than the link quality of the second SUL, and / or the resource utilization of the first SUL is greater than the resource utilization of the second SUL, it is determined to switch the SUL where the terminal device resides from the first SUL to the second SUL. When the capability of the terminal device does not support the second SUL, or the link quality of the first SUL is higher than the link quality of the second SUL, or the resource utilization of the first SUL is less than the resource utilization of the second SUL, it is determined not to switch the SUL where the terminal device resides.

[0113] Through the switching judgment, when it is determined to switch the SUL where the terminal device resides, the SUL where the terminal device resides can be switched through the following step 503. When it is determined not to switch the SUL where the terminal device resides, the terminal device keeps the SUL where it resides unchanged.

[0114] It should be noted that, in some embodiments, the link quality of multiple SULs may also be the uplink quality obtained by the access network device based on the downlink quality reported by the terminal device. The terminal device may measure the downlink of the FDD frequency band to which each of the multiple SULs belongs to obtain the measurement result, and then report it to the access network device. The access network device may use the downlink quality represented by the measurement result to obtain the link quality of each of the multiple SULs by analogy. The embodiment of the present application does not specifically limit the method for determining the link quality of the SUL.

[0115] Step 503: When it is determined to switch the SUL where the terminal device resides, the access network device sends a first message to the terminal device, where the first message is used to reconfigure the SUL where the terminal device resides.

[0116] The terminal device receives a first message sent by the access network device. For example, the first message may be an RRC reconfiguration message. The terminal device switches the resident SUL according to the first message, thereby implementing switching between different SULs.

[0117] In this embodiment, the access network device determines whether to switch the SUL where the terminal device resides based on the capability of the terminal device, the link quality of multiple SULs and / or the resource utilization of multiple SULs. When it is determined to switch the SUL where the terminal device resides, the access network device sends a first message to the terminal device, and the first message is used to reconfigure the SUL where the terminal device resides, thereby improving the uplink transmission capacity and coverage capability of the access network device by switching the SUL where the terminal device resides.

[0118] Figure 6This is a flowchart of another method for configuring SUL provided in an embodiment of the present application. This embodiment is illustrated by taking an access network device and a terminal device as an example. This embodiment is applicable to an FDD cell, such as Figure 6 As shown, the method of this embodiment may include:

[0119] Step 601: The access network device determines a SSB of an FDD cell.

[0120] The SSB includes configuration information of a SUL. For a detailed explanation of the configuration information of the SUL, please refer to Figure 3 The relevant explanations in step 301 of the illustrated embodiment will not be repeated here.

[0121] The SSB may be an SSB sent via the DL of an FDD cell of the access network device.

[0122] The SSB in this embodiment may be a cell defining SSB (Cell Defining SSB).

[0123] Optionally, for an FDD cell, the SSB may also include configuration information of the NUL, and the configuration information of the NUL is used to configure the NUL. The SUL configured by the SSB may serve as an uplink supplement to the NUL to improve the uplink transmission capacity and coverage capability of the access network device.

[0124] Step 602: The access network device broadcasts an SSB via DL.

[0125] The terminal device receives SSB via DL.

[0126] Step 603: The terminal device resides in the SUL according to the configuration information of the SSB SUL and performs uplink transmission through the SUL.

[0127] In one achievable manner, the terminal device may reside in the corresponding SUL according to the configuration information of the SUL of the SSB, for example, perform random access on the SUL, and then perform uplink transmission through the SUL.

[0128] Optionally, for FDD cells, when the SSB also includes configuration information of the NUL, the terminal device can randomly reside in the NUL or the SUL according to the configuration information of the NUL and the configuration information of the SUL.

[0129] In this embodiment, the access network device broadcasts an SSB via DL, and configures a SUL to the terminal device via the SSB, so that the terminal device can use the SUL for uplink transmission. Unlike configuring a NUL for an FDD cell, the embodiment of the present application can configure a SUL for an FDD cell, thereby improving the uplink transmission capacity and coverage capability of the FDD cell. The terminal device can use the SUL for uplink transmission, thereby reasonably utilizing the available spectrum resources for uplink transmission and improving the uplink transmission performance of the communication system.
