Description

Technical Field

[0001] This invention relates to the field of wireless technology, and in particular to a bandwidth configuration method, apparatus, network-side equipment, and base station. Background Technology

[0002] Currently, communication protocols lack a definition for reporting terminal bandwidth capabilities, assuming that the terminal's supported bandwidth meets the system's bandwidth requirements, with different terminals supporting only one bandwidth.

[0139] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0140] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0141] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0142] To address the problem of inaccurate bandwidth configuration based on terminal type in existing network systems supporting multiple bandwidth capabilities, leading to terminal scheduling failures, this invention provides a bandwidth configuration method. In one embodiment, the network-side device transmits Synchronization Signal Blocks (SSBs) at at least two frequency division multiplexing (FDM) locations and configures the same cell identifier information for different SSBs. Different SSBs correspond to different Random Access Hours (RO) resources. By configuring and transmitting SSBs at at least two frequency points within the same cell, different types of terminals can access the network using SSBs at different frequency points. The terminal type can be determined based on the accessed SSB, thus accurately configuring the terminal's Activation BWP.

[0143] One embodiment of the present invention provides a bandwidth configuration method, executed by a network-side device, such as... Figure 1 As shown, the method includes:

[0144] S110, Transmit Synchronization Signal Blocks (SSBs) at at least two frequency domain locations; wherein, different SSBs correspond to different Random Access Hour (RO) resources, and different SSBs include the same cell identifier information;

[0145] S120, The receiving terminal sends a random access message through one of at least two SSBs;

[0146] S130, Configure the active bandwidth portion (BWP) of the terminal according to the random access message.

[0147] The bandwidth configuration method described in this embodiment of the invention, in one implementation, can optionally be applied to, but is not limited to, a 700MHz network, in combination with... Figure 2 As shown, taking the bandwidth configuration method applied to a 700MHz network as an example, the network includes a first type of terminal that supports a first bandwidth range (e.g., 758MHz to 778MHz), a second type of terminal that supports a second bandwidth range (e.g., 778MHz to 800MHz), and a third type of terminal that supports a third bandwidth range (e.g., 758MHz to 800MHz).

[0148] The third bandwidth range includes a portion of the first bandwidth range and a portion of the second bandwidth range.

[0149] In this implementation, the first frequency domain position of the first SSB, which transmits at least two SSBs, is located within the first bandwidth range and the third bandwidth range, but not within the second bandwidth range; the second frequency domain position of the second SSB, which transmits, is located within the second bandwidth range and the third bandwidth range, but not within the first bandwidth range.

[0150] Specifically, for example, such as Figure 2 As shown, the frequency domain position of the first SSB is located in the range of 758MHz to 768MHz within the first bandwidth range, and the frequency domain position of the second SSB is located in the range of 788MHz to 778MHz within the second bandwidth range.

[0151] The bandwidth configuration method described in this embodiment of the invention, by configuring at least two SSBs, each SSB corresponding to a different RO resource, allows a first type of terminal to access the network through the first SSB and a second type of terminal to access the network through the second SSB. By utilizing the location of the RO resource when the terminal sends a random access message, the terminal type can be determined, and the activation BWP of the terminal can be accurately configured according to the terminal type.

[0152] Optionally, based on the above, when the terminal includes a first type, a second type, and a third type, the method further includes:

[0153] Based on the random access message, the preliminary analysis type of the terminal is determined.

[0154] Further, optionally, based on the random access message, determining the preliminary analysis type of the terminal includes:

[0155] The preliminary analysis type of the terminal is determined based on the location of the RO resource when the random access message is sent.

[0156] In step S120, the receiving terminal sends a random access message through one of at least two SSBs, including:

[0157] Receive random access messages sent by a first type of terminal or a third type of terminal through a first SSB; or

[0158] Receive random access messages sent by a second type of terminal or a third type of terminal through a second SSB.

[0159] Using this implementation method, after receiving a random access message sent through the first SSB, it can be determined that the terminal that sent the random access message through the first SSB is of the first type or the third type; after receiving a random access message sent through the second SSB, it can be determined that the terminal that sent the random access message through the first SSB is of the second type or the third type. Therefore, based on the random access message sent by the terminal, the preliminary analysis type of the terminal can be determined.

[0160] Optionally, the network-side equipment pre-configures the second SSB to have a higher priority than the first SSB. When different types of terminals perform cell selection, first-type and third-type terminals access the network through the first SSB, while second-type terminals access the network through the second SSB. Furthermore, during cell reselection, second-type and third-type terminals access the network through the second SSB, while first-type terminals access the network through the first SSB.

[0161] Based on the above, when the priority of the second SSB is pre-configured to be higher than that of the first SSB, in this embodiment of the invention, step S120, receiving a random access message sent by the receiving terminal through one of the at least two SSBs, includes:

[0162] Receive random access messages sent by a first type of terminal or a third type of terminal through a first SSB; or

[0163] Receive random access messages sent by the second type of terminal through the second SSB.

[0164] Furthermore, the bandwidth configuration method described in this embodiment of the invention further includes:

[0165] Receive the cell reselection message sent by the terminal, and determine the terminal type of the terminal based on the cell reselection message;

[0166] The terminal type is one of the first type, the second type, and the third type.

[0167] Optionally, determining the terminal type based on the cell reselection message includes:

[0168] If the preliminary analysis type includes a first type supporting a first bandwidth range and a third type supporting a third bandwidth range, and the cell reselection message is sent through the first SSB, then the terminal type of the terminal is determined to be the first type; or

[0169] If the preliminary analysis type includes a first type supporting a first bandwidth range and a third type supporting a third bandwidth range, and the cell reselection message is sent via the second SSB, then the terminal type of the terminal is determined to be the third type; or

[0170] If the preliminary analysis type includes a second type supporting a second bandwidth range and a third type supporting a third bandwidth range, and the cell reselection message is sent via the second SSB, then the terminal type of the terminal is determined to be the second type; or

[0171] If the preliminary analysis type includes a second type that supports a second bandwidth range and a third type that supports a third bandwidth range, and the cell reselection message is sent through the first SSB, then the terminal type of the terminal is determined to be the third type.

[0172] Therefore, by using the bandwidth configuration method described in this embodiment of the invention, the specific type of the terminal can be determined through the terminal access and reselection process.

[0173] In this embodiment of the invention, step S130, configuring the active bandwidth portion (BWP) of the terminal according to the random access message, includes:

[0174] When the random access message is sent through the first SSB of at least two SSBs, the terminal is configured with an active BWP of a first range based on the transmission frequency of the first SSB.

[0175] When the random access message is sent through the second SSB of at least two SSBs, the terminal is configured with a second range of active BWP based on the transmission frequency of the second SSB.

[0176] Optionally, when a random access message is sent through the first SSB, an active BWP with a bandwidth of 30MHz (first range) is configured for the terminal based on the transmission frequency of the first SSB; when a random access message is sent through the second SSB, an active BWP with a bandwidth of 20MHz (second range) is configured for the terminal based on the transmission frequency of the second SSB.

[0177] Optionally, after configuring a first range of activated BWPs for the terminal based on the transmission frequency of the first SSB, the method further includes:

[0178] Send first reconfiguration information to the terminal to instruct the terminal to perform cell reconfiguration on the active BWP in the second range; or

[0179] After configuring the terminal with a second range of activated BWP based on the transmission frequency of the second SSB, the method further includes:

[0180] Send a second reconfiguration message to the terminal to instruct the terminal to perform cell reconfiguration on the active BWP in the first range.

[0181] Specifically, when the network-side equipment determines that the utilization rates of Physical Resource Blocks (PRBs) at different frequencies within a cell are uneven, it sends either a first reconfiguration message or a second reconfiguration message to the terminal. For example, if it determines that the PRB utilization rate corresponding to the active BWP in the first configured range is high, while the PRB utilization rate corresponding to the active BWP in the second range is low, it sends either the first or second reconfiguration message to the terminal. By sending either the first or second reconfiguration message to the terminal, BWP reconfiguration is achieved, thereby ensuring a balance in the utilization rates of PRBs at different frequencies.

[0182] In one implementation, when the terminal is a first type or a third type terminal, the network-side device sends first reconfiguration information to the terminal, instructing the terminal to perform cell reconfiguration on the active BWP in the second range. That is, it instructs either a first type or third type terminal accessed via the first SSB to perform cell reconfiguration on the active BWP in the second range. The third type terminal can successfully reconfigure, while the first type terminal, if reconfiguration fails, will return to the active BWP in the first range for reconfiguration. In another implementation, when the terminal is a second type or a third type terminal, the network-side device sends second reconfiguration information to the terminal, instructing the terminal to perform cell reconfiguration on the active BWP in the first range. That is, it instructs either a second type or third type terminal accessed via the second SSB to perform cell reconfiguration on the active BWP in the first range. The third type terminal can successfully reconfigure, while the second type terminal, if reconfiguration fails, will return to the active BWP in the second range for reconfiguration.

[0183] By employing the above reconfiguration process, the BWP conversion of the third type of terminal can be completed, achieving a balance in the utilization rate of PRBs at different frequencies.

[0184] Optionally, in the case where the bandwidth configuration method of the present invention configures a first range of active BWPs for the terminal based on the transmission frequency point of the first SSB, the method further includes:

[0185] During cell handover, first neighbor cell information is sent to the terminal. This first neighbor cell information includes cell information and neighbor cell information corresponding to the first SSB; or

[0186] When configuring a second range of activated BWP for the terminal based on the transmission frequency of the second SSB, the method further includes:

[0187] During cell handover, second neighbor cell information is sent to the terminal. The second neighbor cell information includes cell information and neighbor cell information corresponding to the second SSB.

[0188] Using the bandwidth configuration method described in this embodiment of the invention, one cell information corresponds to two SSB frequency points. During cell neighbor cell configuration, two levels of neighbor cell configuration parameters are generated. Specifically, during cell handover, the network-side device sends cell information and corresponding neighbor cell information to terminals accessing via the first SSB, and sends cell information and corresponding neighbor cell information to terminals accessing via the second SSB, based on the neighbor cell information distributed by the SSB accessed by the terminal, for cell handover purposes.

[0189] In addition, network-side equipment sends full-frequency information to all terminals for cell reselection.

[0190] In this embodiment of the invention, optionally, the cell information includes the Physical Cell Identifier (PCI) and / or the New Radio Access Cell Global Identifier (NCGI).

[0191] The bandwidth configuration method described in this embodiment of the invention configures at least two frequency points during cell configuration. Optionally, when configuring two frequency points, one frequency point has a higher priority than the other, or the priorities of the two frequency points are configured to be the same. Furthermore, optionally, two SSB frequency points are configured in the absolute FrequencySSB within the downlink frequency information element Frequency Info DL IE, each corresponding to a different SSB index.

[0192] In one embodiment of the bandwidth configuration method described in this invention, the network-side device configures at least two SSB frequency points for a cell, so that each SSB corresponds to a different RO resource. In this way, at least two frequency points of SSB are configured and transmitted in the same cell, so that different types of terminals can access the SSB at different frequency points. The terminal type can be determined according to the accessed SSB, so as to accurately configure the terminal's activation BWP.

[0193] Another aspect of this invention provides a bandwidth configuration method, executed by a terminal, such as... Figure 3 As shown, the method includes:

[0194] S310, Obtain the first SSB transmitted by the network-side device at the first frequency domain location; wherein, the first SSB is one of the SSBs transmitted by the network-side device at at least two frequency domain locations; different SSBs correspond to different random access opportunity (RO) resources, and different SSBs include the same cell identifier information;

[0195] S320, a random access message is sent to the network-side device through the first SSB;

[0196] S330, Obtain the active bandwidth portion (BWP) configured by the network-side device for the terminal based on the random access message.

[0197] Using the bandwidth configuration method described in this embodiment of the invention, the network-side device configures at least two SSB frequency points for a cell, so that each SSB corresponds to a different RO resource. In this way, by configuring and sending at least two SSB frequency points in the same cell, different types of terminals can access the SSB at different frequency points. This allows the network-side device to determine the terminal type based on the SSB that the terminal accesses, so as to accurately configure the terminal's activation BWP.

[0198] Optionally, in the bandwidth configuration method, the terminal type is one of a first type and a third type, or the terminal type is one of a second type and a third type;

[0199] The first type of terminal is a terminal that supports a first bandwidth range, the second type of terminal is a terminal that supports a second bandwidth range, and the third type of terminal is a terminal that supports a third bandwidth range.

[0200] Wherein, when the terminal type is one of the first type and the third type, the first frequency domain position is located in the first bandwidth range and the third bandwidth range, but not in the second bandwidth range; when the terminal type is one of the second type and the third type, the first frequency domain position is located in the second bandwidth range and the third bandwidth range, but not in the first bandwidth range.

[0201] Optionally, combined Figure 2 As shown, the first type of terminal is a terminal that supports a first bandwidth range (e.g., 758MHz to 778MHz), the second type of terminal is a terminal that supports a second bandwidth range (e.g., 778MHz to 800MHz), and the third type of terminal is a terminal that supports a third bandwidth range (e.g., 758MHz to 800MHz).

[0202] In this embodiment of the present invention, optionally, in combination with Figure 2 As shown, the first SSB can be an SSB transmitted within a first bandwidth range of 758MHz to 768MHz, or an SSB transmitted within a second bandwidth range of 788MHz to 778MHz. Specifically, when the first SSB is either an SSB transmitted within the first bandwidth range of 758MHz to 768MHz or an SSB transmitted within the second bandwidth range of 788MHz to 778MHz, the second SSB is the other one of the two.

[0203] In this embodiment of the invention, the terminal is one of a first type of terminal, a second type of terminal, and a third type of terminal.

[0204] Optionally, in step S330, obtaining the active bandwidth portion (BWP) configured by the network-side device for the terminal based on the random access message includes:

[0205] When the terminal type is one of the first type and the third type, the active BWP of the first range configured by the network side device based on the transmission frequency of the first SSB for the terminal is obtained;

[0206] When the terminal type is one of the second type and the third type, the network-side device acquires the second range of the active BWP configured for the terminal based on the transmission frequency of the first SSB.

[0207] Optionally, the bandwidth configuration method further includes:

[0208] When the terminal type is the first type or the second type, a cell reselection message is sent to the network-side device through the first SSB; or

[0209] When the terminal type is the third type, a cell reselection message is sent to the network-side device through the second SSB.

[0210] Specifically, when performing cell reselection, if the terminal is of type 1 or type 2, it sends a cell reselection message to the network-side device through the SSB (first SSB) it has accessed; if the terminal is of type 3, it sends a cell reselection message to the network-side device through another SSB (second SSB) of the SSB it has accessed.

[0211] Optionally, when the terminal type is one of the first type and the third type, after obtaining the activated BWP of the first range configured by the network-side device for the terminal based on the transmission frequency of the first SSB, the method further includes:

[0212] Obtain the first reconfiguration information sent by the network-side device, which is used to instruct the terminal to perform cell reconfiguration on the active BWP in the second range; or

[0213] When the terminal type is one of the second type and the third type, after obtaining the activated BWP of the second range configured by the network-side device for the terminal based on the transmission frequency of the first SSB, the method further includes:

[0214] The second reconfiguration information sent by the network-side device is obtained, which is used to instruct the terminal to perform cell reconfiguration on the active BWP in the first range.

[0215] Specifically, when the network-side equipment determines that the utilization rate of PRBs at different frequencies in a cell is uneven, it sends a first reconfiguration message or a second reconfiguration message to the terminal. For example, if it determines that the PRB utilization rate corresponding to the active BWP in the first configured range is high, while the PRB utilization rate corresponding to the active BWP in the second range is low, it sends the first reconfiguration message or the second reconfiguration message to the terminal. By sending the first reconfiguration message or the second reconfiguration message to the terminal, the terminal's BWP is reconfigured to ensure the balance of PRB utilization rates at different frequencies.

[0216] In one implementation, when the terminal is a first type or a third type terminal, the network-side device sends first reconfiguration information to the terminal, instructing the terminal to perform cell reconfiguration on the active BWP in the second range. That is, it instructs either a first type or third type terminal accessed via the first SSB to perform cell reconfiguration on the active BWP in the second range. The third type terminal can successfully reconfigure, while the first type terminal, if reconfiguration fails, will return to the active BWP in the first range for reconfiguration. In another implementation, when the terminal is a second type or a third type terminal, the network-side device sends second reconfiguration information to the terminal, instructing the terminal to perform cell reconfiguration on the active BWP in the first range. That is, it instructs either a second type or third type terminal accessed via the second SSB to perform cell reconfiguration on the active BWP in the first range. The third type terminal can successfully reconfigure, while the second type terminal, if reconfiguration fails, will return to the active BWP in the second range for reconfiguration.

[0217] By employing the above reconfiguration process, the BWP conversion of the third type of terminal can be completed, achieving a balance in the utilization rate of PRBs at different frequencies.

[0218] In another embodiment, optionally, the bandwidth configuration method further includes:

[0219] During cell handover, the first neighbor cell information sent by the network-side device is obtained. The first neighbor cell information includes cell information and neighbor cell information corresponding to the first SSB.

[0220] Using the bandwidth configuration method described in this embodiment of the invention, one cell information corresponds to two SSB frequency points. When configuring neighboring cells, two levels of neighboring cell configuration parameters are generated. Specifically, during cell handover, the network-side device sends cell information and the corresponding neighboring cell information of the first SSB to the terminal accessing the terminal based on the neighboring cell information issued by the SSB accessed by the terminal.

[0221] To address the problem that existing network systems, which include terminals supporting multiple bandwidth capabilities, cannot accurately configure bandwidth according to terminal type, leading to terminal scheduling failures, this invention provides a bandwidth configuration method. In one embodiment, based on a reconfiguration indication information sent by the terminal indicating a failed BWP reconfiguration, reconfiguration or reconstruction based on the failed BWP reconfiguration is implemented until the terminal reconfigures successfully, ensuring accurate configuration of the terminal's active BWP.

[0222] This invention provides a bandwidth configuration method, executed by a network-side device, such as... Figure 4 As shown, the method includes:

[0223] S410, a reconfiguration message is sent to the terminal; the reconfiguration message includes the bandwidth portion (BWP) configured for the terminal;

[0224] S420, Obtain reconfiguration indication information to indicate that the BWP reconfiguration of the terminal has failed;

[0225] S430, according to the reconfiguration instruction information, change the BWP configured on the terminal, and send a reconfiguration message including the changed BWP to the terminal until the terminal is successfully reconfigured.

[0226] The bandwidth configuration method described in this embodiment of the invention, in one implementation, can optionally be applied to, but is not limited to, a 700MHz network, in combination with... Figure 5 As shown, taking the bandwidth configuration method applied to a 700MHz network as an example, the network includes a first type of terminal that supports a first bandwidth range (e.g., 758MHz to 778MHz), a second type of terminal that supports a second bandwidth range (e.g., 778MHz to 800MHz), and a third type of terminal that supports a third bandwidth range (e.g., 758MHz to 800MHz).

[0227] The third bandwidth range includes a portion of the first bandwidth range and a portion of the second bandwidth range.

[0228] Using the bandwidth configuration method described in this embodiment, the frequency point position of the SSB transmission is configured to be located within the overlapping bandwidth range of the first bandwidth range and the second bandwidth range, such as... Figure 5 As shown, SSB0 is transmitted within a bandwidth range of 770MHz to 780MHz, enabling terminals of the first type, the second type, and the third type to access the network without distinction.

[0229] Furthermore, after different types of terminals access the network without discrimination, a reconfiguration message is sent to the terminal to indicate the BWP configured for the terminal. The terminal then performs BWP reconfiguration according to the reconfiguration message. If BWP reconfiguration fails, a reconfiguration indication message indicating the failure is sent to the network-side device. This enables reconfiguration or reconstruction based on BWP reconfiguration failure until the terminal reconfigures successfully, ensuring accurate configuration of the terminal's active BWP.

[0230] Optionally, when sending a reconfiguration message to the terminal, the BWP located in the first bandwidth range can be configured for the terminal first. When the reconfiguration indication information indicating that the BWP reconfiguration has failed is received from the terminal, and the reconfiguration message is sent to the network-side device again, the BWP located in the second bandwidth range can be configured for the terminal. Based on this principle, the configured BWP is changed multiple times until the terminal is successfully configured.

[0231] In this embodiment of the invention, optionally, when sending a reconfiguration message to the terminal, it can be implemented through the RRC reconfiguration process to support the method of having the terminal provide feedback on whether bandwidth capability is supported.

[0232] In existing solutions, RRC reconfiguration fails to achieve partial configuration success, while BWP reconfiguration fails, leading to a rebuild. The network-side device cannot obtain reconfiguration failure information from the terminal. After rebuilding, the terminal reverts to its previous reconfiguration state and reconfigures the same information again, continuing until the terminal successfully reconfigures or the reconfiguration connection drops and rebuilds. However, this method results in continuous failures in BWP reconfiguration. In contrast, the method described in this invention allows the network-side device to obtain reconfiguration indication information indicating BWP reconfiguration failure after sending a reconfiguration message to the terminal.

[0233] In one embodiment, the reconfiguration message may optionally include dedicated system information for instructing the reconfiguration of the terminal's BWP.

[0234] The method further includes, after sending a reconfiguration message to the terminal:

[0235] Obtain the reconfiguration failure message sent by the terminal after reconfiguring according to the reconfiguration message;

[0236] Obtaining the reconfiguration instruction information includes:

[0237] Based on the reconfiguration failure message, obtain the reconfiguration indication information used to indicate that the terminal BWP reconfiguration failed.

[0238] In this implementation, a dedicated Information Element (IE) for BWP configuration is added to send reconfiguration messages. These reconfiguration messages include only dedicated system information indicating that the terminal's BWP should be reconfigured. Based on this dedicated system information, if the terminal fails to reconfigure its BWP, it will perform a reconstruction, with the reconstruction reason being reconfiguration failure. The network-side device can determine the reason for the reconfiguration failure as BWP reconfiguration failure based on the reconfiguration failure message sent by the terminal. After the terminal reconstructs, the network-side device can modify the BWP configuration and send the reconfiguration message to the terminal again until the terminal successfully reconfigures.

[0239] Alternatively, in another embodiment, the method may further include:

[0240] Obtain the reconstruction information sent by the terminal after reconfiguring according to the reconfiguration message; the reconstruction reason in the reconstruction information includes BWP configuration failure;

[0241] Obtaining the reconfiguration indication information includes:

[0242] The reconfiguration instruction information is obtained based on the reason for the failure of BWP configuration in the reconstruction information.

[0243] This implementation method adds a reconstruction failure reason without changing the reconfiguration information element (IE). Based on the existing reconstruction reasons, a new reconstruction reason, BWP configuration failure, is added. Thus, based on the reconstruction reason including BWP configuration failure sent by the network-side device, a reconfiguration indication information indicating BWP configuration failure is obtained. After the terminal reconfigures and reverts to the original bandwidth configuration, the network-side device can reconfigure the BWP to the updated BWP configuration and send a reconfiguration message to the terminal again until the terminal reconfigures successfully.

[0244] In another implementation, obtaining the reconfiguration instruction information includes:

[0245] Obtain the reconstruction information sent by the terminal after reconfiguring according to the reconfiguration message;

[0246] If it is determined that the reconstruction information includes BWP information, then reconfiguration indication information indicating BWP reconfiguration failure is obtained.

[0247] Optionally, a reconfiguration message including the modified BWP is sent to the terminal, including:

[0248] Using the last successful configuration information element of the terminal, a reconfiguration message for the modified BWP is sent to the terminal.

[0249] This implementation method enhances the functionality of network-side devices. If a data packet carrying BWP configuration information is not received from the terminal indicating successful configuration, the BWP is reconfigured. This involves using the last successfully configured IE and changing the sub-band bandwidth configuration to achieve a reconstruction or reconfiguration process based on the reason for reconfiguration failure.

[0250] Typically, when a terminal initiates a reconstruction based on a reconfiguration failure, the reconstruction reason indicates that the reconfiguration failed, but the corresponding reconfiguration ID number cannot be found. Existing protocols use the configuration from the terminal's last successful reconfiguration, but cannot obtain the reason for the reconfiguration failure. To reconfigure the BWP again after a reconfiguration failure and reconstruction, base station functionality needs to be enhanced to enable reconstruction or reconfiguration based on the reason for the reconfiguration failure.

[0251] Specifically, if the reconfiguration failure does not carry BWP information, the original processing method is followed. If the reconfiguration failure carries BWP information, after the terminal initiates a reconstruction, the network-side device confirms whether the reconfiguration failure carries BWP information. If it does, the network-side device initiates BWP reconfiguration again, carrying the changed BWP in the reconfiguration message, and other reconfiguration parameters revert to the state of the last successful reconfiguration. That is, if no data packet carrying bandwidth configuration (BWP) information is received from the terminal indicating successful configuration, the last successfully configured IE is used, and the sub-band bandwidth configuration is changed.

[0252] For example, the network-side device records the reconfiguration ID with BWP for each user, and counts the reconfiguration IDs that failed to reconfigure before the terminal is rebuilt. If these reconfiguration IDs carry bandwidth configuration (BWP) information, the BWP update reconfiguration process is initiated again after the reconstruction.

[0253] The bandwidth configuration method described in this embodiment of the invention enhances the RRC reconfiguration IE and / or adds RRC reconstruction reasons, enabling the base station to know that the terminal reconfiguration failure is due to BWP configuration failure, and the reconfiguration after reconstruction updates the BWP information. Another implementation enhances the functionality of network-side equipment to achieve reconstruction or reconfiguration based on the reconfiguration failure reason. If no data packet carrying bandwidth configuration (BWP) information is received from the terminal indicating successful configuration, the last successfully configured IE is used, and the sub-band bandwidth configuration is changed. Alternatively, in another implementation, a BWP reconfiguration failure process can be added to the existing RRC reconfiguration process. This BWP reconfiguration failure process requires the network-side equipment to only perform BWP reconfiguration, enabling reconfiguration or reconstruction based on BWP reconfiguration failure and ensuring accurate configuration of the terminal's activated BWP.

[0254] Another embodiment of this invention also provides a bandwidth configuration method, executed by a terminal, such as... Figure 6 As shown, the method includes:

[0255] S610, Obtain a reconfiguration message sent by the network-side device; the reconfiguration message includes the bandwidth portion (BWP) configured for the terminal;

[0256] S620, if the reconfiguration fails according to the BWP, a reconfiguration indication message indicating the failure of BWP reconfiguration is sent to the network-side device.

[0257] S630, Obtain the reconfiguration message including the modified BWP resent by the network-side device according to the reconfiguration instruction information;

[0258] S640, if reconfiguration fails according to the BWP, a reconfiguration instruction message is sent to the network-side device again until reconfiguration is successful according to the BWP sent by the network-side device.

[0259] Using the bandwidth configuration method described in this embodiment of the invention, the network-side device, based on the reconfiguration indication information sent by the terminal indicating that the BWP reconfiguration has failed, realizes reconfiguration or reconstruction based on the failure of BWP reconfiguration until the terminal reconfigures successfully, thus ensuring accurate configuration of the terminal's active BWP.

[0260] Optionally, in the bandwidth configuration method, the reconfiguration message includes dedicated system information for instructing the reconfiguration of the terminal's BWP;

[0261] Sending a reconfiguration indication message indicating BWP reconfiguration failure to the network-side device, including:

[0262] A reconfiguration failure message is sent to the network-side device, and the reconfiguration failure message is used as the reconfiguration indication information to indicate that the BWP reconfiguration has failed.

[0263] Optionally, in the bandwidth configuration method, sending reconfiguration indication information indicating BWP reconfiguration failure to the network-side device includes:

[0264] The network-side device is sent reconstruction information indicating that BWP reconfiguration has failed. The reconstruction reason in the reconstruction information includes BWP configuration failure. The reconstruction reason including BWP configuration failure is used as the reconfiguration indication information to indicate that BWP reconfiguration has failed.

[0289] If the preliminary analysis type includes a first type supporting a first bandwidth range and a third type supporting a third bandwidth range, and the cell reselection message is sent through the first SSB, then the terminal type of the terminal is determined to be the first type; or

[0290] If the preliminary analysis type includes a first type supporting a first bandwidth range and a third type supporting a third bandwidth range, and the cell reselection message is sent via the second SSB, then the terminal type of the terminal is determined to be the third type; or
