FIG1 is a schematic diagram showing an exemplary system architecture that can be applied to a terminal-specific bandwidth configuration method according to an embodiment of the present disclosure.

As shown in FIG. 1 , the system architecture 100 may include a terminal device 110 , a network 120 , and a server 130 .

The network 120 is used to provide a medium for a communication link between the terminal device 110 and the server 130. The network 120 may be a wired network or a wireless network. For example, the network 120 includes a radio access network (RAN) and a core network.

In some embodiments, the wireless access network or wired network described above uses standard communication technology and/or protocols. Network 120 is typically the Internet, but may also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a dedicated network or any combination of a virtual private network). In some embodiments, technologies and/or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged over the network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec), etc. may be used to encrypt all or some links. In other embodiments, customized and/or dedicated data communication technologies may also be used to replace or supplement the above data communication technologies.

It can be understood that for a wireless communication system, it is a network that provides wireless communication functions. The communication system can adopt different communication technologies, such as code division multiple access, bandwidth code division multiple access, time division multiple access, frequency division multiple access, orthogonal frequency division multiple access, single carrier frequency division multiple access, carrier sense multiple access/collision avoidance. According to the capacity, rate, delay and other factors of different networks, the network can be divided into 2G (generation) network, 3G network, 4G network or future evolution network, such as 5G network, 5G network is referred to as network or system. In the present disclosure, the wireless access network includes network equipment, which can be, for example, a wireless access network entity; the core network includes core network equipment. Among them, the wireless access network entity can also be called a base station. The wireless access network can provide network services for the terminal device 110 through the network equipment, and different operators can provide different network services for the terminal device 110. It can also be understood that different operators correspond to different operator networks.

The terminal device 110, also known as terminal, user terminal, user equipment (UE), etc., can be various electronic devices, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, etc.

In some embodiments, the client of the application installed in different terminal devices 110 is the same, or is a client of the same type of application based on different operating systems. Based on the different terminal platforms, the specific form of the client of the application can also be different, for example, the application client can be a mobile client, a PC client, etc.

The server 130 may be a server that provides various services, such as a background management server that provides support for devices operated by the user using the terminal device 110. The background management server may analyze and process the received request and other data, and feed back the processing results to the terminal device 110.

In some embodiments, server 130 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), as well as big data and artificial intelligence platforms.

Those skilled in the art will appreciate that the number of terminal devices 110, networks 120, and servers 130 in FIG1 is merely illustrative, and any number of terminal devices 110, networks 120, and servers 130 may be provided according to actual needs. The embodiments of the present disclosure are not limited thereto.

In the actual network deployment process, the carrier bandwidth of some 4G re-cultivated spectrum is not defined in the 5G R17 standard. Take a certain communication operator as an example. For example, in the 800MHz frequency band, it has a total spectrum bandwidth of 11MHz, from 824MHz to 835MHz or from 869MHz to 880MHz. However, in the current 5G standard, 11MHz is not defined. These spectrum bandwidths are called irregular bandwidths, or non-standard bandwidths. In the 11MHz irregular bandwidth scenario, the relevant technology uses a standard bandwidth of 10MHz for coverage. This solution is called a smaller CBW (Channel Bandwidth) solution.

The concept of terminal dedicated bandwidth (UE-specific CBW) is introduced in 5G. UE-specific CBW is used to Indicates the bandwidth size and carrier position of the CBW of a specific terminal device to support users to flexibly use the spectrum. Although the standard does not explicitly specify that the UE-specific CBW must be limited to the BS (Base Station) CBW, in normal scenarios, the UE-specific CBW is still included in the CBW indicated in SIB1. If the network device configures a UE-specific CBW for the terminal device that exceeds the CBW indicated in SIB1, the terminal device cannot be guaranteed to work properly.

For the case of irregular bandwidth, take the irregular bandwidth of 11MHz as an example. Under the smaller CBW solution, only 10MHz carrier bandwidth can be used to cover the 11MHz spectrum. When the subcarrier spacing is 15kHz (i.e. SCS@15kHz), the maximum number of physical resource blocks (PRBs) available for the 10MHz carrier bandwidth is 52PRBs, while in the irregular bandwidth scenario, the maximum number of PRBs available for the 11MHz spectrum is 56PRBs. It can be seen that in the irregular bandwidth scenario, compared with the standard bandwidth scenario, 4PRB resources will be wasted.

In the relevant technologies or standards, the 3GPP RAN4 meeting discussed whether the terminal equipment supports UE-specific CBW greater than the CBW indicated by SIB1 for irregular bandwidth SI. However, no unified opinion was reached.

Different manufacturers have different opinions on whether terminal devices can support UE-specific CBW greater than the CBW indicated by SIB1. If all terminal devices are required to support it, some terminal devices may not work properly. If all terminal devices are not required to support it, it will cause a waste of scarce spectrum resources in the non-regular bandwidth scenario. How to reasonably use non-regular bandwidth to improve the utilization rate of scarce spectrum resources has become an urgent problem to be solved.

Based on this, a terminal-dedicated bandwidth configuration method is provided in an embodiment of the present disclosure, wherein the network device sends the non-regular bandwidth to the terminal device via broadcast information, and the terminal device accesses the cell via a first standard bandwidth slightly smaller than the non-regular bandwidth according to the 38.331 protocol, and receives a report from the terminal device as to whether it has the ability to support the configuration of a terminal-dedicated bandwidth greater than the carrier bandwidth. If the terminal device has the above capability, a second standard bandwidth slightly larger than the non-regular bandwidth is configured for the terminal device. For the non-regular bandwidth scenario, a terminal capability reporting mechanism is introduced to enable the network device to configure a terminal-dedicated bandwidth for the terminal device according to the terminal capability report, thereby improving the utilization rate of the non-regular bandwidth, avoiding the waste of scarce spectrum resources, and improving the user experience.

The present exemplary implementation is described in detail below with reference to the accompanying drawings and embodiments.

First, a method for configuring a terminal-specific bandwidth is provided in an embodiment of the present disclosure, and the method can be executed by any electronic device with computing and processing capabilities. In some embodiments, the method for configuring a terminal-specific bandwidth provided in an embodiment of the present disclosure can be executed by a terminal device; in other embodiments, the method for configuring a terminal-specific bandwidth provided in an embodiment of the present disclosure can be executed by a network device, such as a base station; in other embodiments, the method based on CAG model communication provided in an embodiment of the present disclosure can also be implemented by a terminal device and a network device through interaction.

FIG2 shows a flow chart of a method for configuring a terminal dedicated bandwidth provided by an embodiment of the present disclosure. As shown in FIG2 , the method for configuring a terminal dedicated bandwidth provided by an embodiment of the present disclosure is applied to a network device, and the method includes:

S202: Send the carrier bandwidth to the terminal device via broadcast information.

In one embodiment, as shown in FIG3 , the broadcast information may send the carrier bandwidth to the terminal device in the system information block 1 (System Information Block 1, SIB1), and the broadcast information may also send the initial bandwidth part (Bandwidth Part, BWP) in SIB1. It should be noted that the carrier bandwidth is represented by the maximum number of physical resource blocks that can be used for the irregular bandwidth, and the carrier bandwidth may include at least one irregular bandwidth of different frequency bands, or the carrier bandwidth may also include at least one irregular bandwidth of the same frequency band.

S204. When a terminal device accesses a cell, the receiving terminal device reports whether it has the capability to support configuring a terminal-specific bandwidth (UE-specific CBW) that is larger than the carrier bandwidth.

In some embodiments, the terminal device receives SIB1 sent by the network device (such as gNB), and according to the description of the 38.331 protocol, the terminal device accesses the cell through the initial standard bandwidth, where the initial standard bandwidth is the standard bandwidth actually used by the terminal device when accessing the cell this time. For example, if the carrier bandwidth in SIB1 is configured as 56PRB (corresponding to the irregular bandwidth of 11MHz), and the initial BWP is configured as 52PRB, the terminal device determines the standard bandwidth that can be transmitted between the initial BWP and the carrier bandwidth according to the description of the 38.331 protocol, such as 10MHz, and accesses the cell through the 10MHz standard bandwidth.

When establishing communication between a terminal device and a network device, the terminal device can use a variety of methods to report whether it has the ability to support configuration of a terminal-specific bandwidth greater than the carrier bandwidth, so that the network device can configure the corresponding standard bandwidth based on the above capabilities of the terminal device.

For example, the terminal device sends the above capability information to the network device through an RRC connection establishment completion message; it can also send it to the network device by sending an Attach message carrying the above capability information; it can also send the above capability information to the network device by sending a TAU request message, a service request message or a dedicated capability report message carrying the above capability information.

In one embodiment, the above-mentioned capabilities of the terminal device can be optionally reported. For terminal devices that do not have the above-mentioned capabilities, there is no need to report them; for terminal devices that have the above-mentioned capabilities, the above-mentioned capabilities are reported.

In some embodiments, the above-mentioned capabilities of the terminal device must be reported. For example, a capability identifier can be used to indicate whether the terminal device has the ability to support the configuration of a terminal-specific bandwidth greater than the carrier bandwidth, and the capability identifier can be represented by numbers, text, symbols, etc. Exemplarily, the capability identifier uses 0 to indicate that the terminal device does not have the ability to support the configuration of a terminal-specific bandwidth greater than the carrier bandwidth, and the capability identifier uses 1 to indicate that the terminal device has the ability to support the configuration of a terminal-specific bandwidth greater than the carrier bandwidth.

It should be noted that the reporting method and content of the above capabilities of the terminal device can be determined according to actual conditions.

S206. If the terminal device has the capability of supporting configuration of a terminal-specific bandwidth that is greater than the carrier bandwidth, a first standard bandwidth is configured for the terminal device, where the first standard bandwidth is greater than the carrier bandwidth.

In one embodiment, if the network device receives a signal from the terminal device that it has the capability to support the configuration of a UE-specific CBW greater than the carrier bandwidth indicated by SIB1, the network device configures the first standard bandwidth of the terminal device so that the terminal device accesses the cell according to the first standard bandwidth, and the first standard bandwidth is greater than the adjacent standard bandwidth of the carrier bandwidth. The bandwidth is accurate, so there is no need to change or upgrade network equipment, and high-quality services can be provided to terminal devices, improving user experience.

For example, after determining that the terminal device has the ability to support the configuration of a UE-specific CBW that is larger than the carrier bandwidth indicated by SIB1, the network device may carry the first standard bandwidth information in a dedicated message sent to the UE. These dedicated messages include: RRC connection establishment message, Attach acceptance message, or RRC reconfiguration message, etc.

Exemplarily, the first standard bandwidth may be an adjacent standard bandwidth that is larger than the carrier bandwidth. For example, if the carrier bandwidth is 11 MHz, the first standard bandwidth may be determined to be 15 MHz.

In some embodiments, if the terminal device has the ability to support configuring a terminal-specific bandwidth that is greater than the carrier bandwidth, configuring a second standard bandwidth for the terminal device includes: configuring an uplink first standard bandwidth and a downlink first standard bandwidth for the terminal device.

The embodiment of the present disclosure provides a method for configuring terminal-dedicated bandwidth. The network device sends the carrier bandwidth to the terminal device through broadcast information. The terminal device accesses the cell through the initial standard bandwidth according to the 38.331 protocol. The receiving terminal device reports whether it has the ability to support the configuration of a terminal-dedicated bandwidth greater than the carrier bandwidth. If the terminal device has the above capability, a first standard bandwidth slightly larger than the irregular bandwidth is configured for the terminal device. For the irregular bandwidth scenario, a terminal capability reporting mechanism is introduced to enable the network device to configure the terminal-dedicated bandwidth for the terminal device according to the terminal capability report, thereby improving the utilization rate of the irregular bandwidth, avoiding the waste of scarce spectrum resources, and improving the user experience.

In one embodiment, the carrier bandwidth is represented by the maximum number of physical resource blocks that can be used by the irregular bandwidth.

For different irregular bandwidths, taking the subcarrier spacing (SCS@15kHz) as an example, the maximum number of PRBs corresponding to the maximum (Bandwidth Part, BWP) is shown in Table 1.

Table 1 Correspondence between irregular bandwidth and maximum number of PRBs

In one embodiment, the maximum number of physical resource blocks that can be used for the irregular bandwidth is obtained by: determining the adjacent standard bandwidth of the irregular bandwidth, wherein the adjacent standard bandwidth includes an adjacent standard bandwidth that is larger than the irregular bandwidth, or the adjacent standard bandwidth includes an adjacent standard bandwidth that is smaller than the irregular bandwidth; and determining the maximum number of physical resource blocks that can be used for the irregular bandwidth based on the protection band of the adjacent standard bandwidth.

It should be noted that the operator determines the maximum available standard bandwidth and irregular bandwidth according to the available bandwidth, and can obtain the adjacent standard bandwidth of the irregular bandwidth. For example, if the irregular bandwidth is 11 MHz, the adjacent standard bandwidth can be 10 MHz or 15 MHz.

A guard band (Guard Band) adjacent to the standard bandwidth is used to meet the first standard bandwidth requirement of the terminal device. The maximum number of PRBs that can be used for the irregular bandwidth can be determined based on the guard band.

In one embodiment, for a terminal that does not report a carrier bandwidth that supports configuration greater than that indicated by SIB1, The network device receives a report from the terminal device that it does not have the ability to support a terminal-specific bandwidth greater than the carrier bandwidth indicated by SIB1, and determines that the terminal device supports configuring a second standard bandwidth, and the second standard bandwidth is less than the carrier bandwidth. It should be noted that the second standard bandwidth is an adjacent standard bandwidth less than the carrier bandwidth.

Exemplarily, when the terminal device does not have the ability to support a terminal-specific bandwidth greater than the carrier bandwidth indicated by SIB1, a second standard bandwidth slightly smaller than the carrier bandwidth is used to provide services for the terminal device. For example, when the carrier bandwidth is 11 MHz, the second standard bandwidth can be covered by 10 MHz.

In the terminal dedicated bandwidth configuration method provided by the embodiment of the present disclosure, the network device sends the non-regular bandwidth to the terminal device through broadcast information, the terminal device accesses the cell through the first standard bandwidth slightly smaller than the non-regular bandwidth according to the 38.331 protocol, and receives the report of whether the terminal device has the ability to support the configuration of the terminal dedicated bandwidth greater than the carrier bandwidth. If the terminal device does not have the above capability, a second standard bandwidth slightly smaller than the non-regular bandwidth is configured for the terminal device. For the non-regular bandwidth scenario, by introducing the terminal capability reporting mechanism, the network device configures the terminal dedicated bandwidth for the terminal device according to the terminal capability report, thereby improving the utilization rate of the non-regular bandwidth, avoiding the waste of scarce spectrum resources, and improving the user experience.

In order to deepen the understanding of the above embodiment, a detailed description is given below in conjunction with FIG. 4 .

As shown in FIG4 , a method for configuring a terminal dedicated bandwidth mainly includes the following processes:

S401, gNB 410 sends the carrier bandwidth to the terminal device 110 via broadcast information.

It should be noted that the broadcast information can send the carrier bandwidth to the terminal device in the system message block 1 SIB1, or send the initial BWP to the terminal device in SIB1, and the carrier bandwidth is greater than the initial BWP; the carrier bandwidth can include at least one irregular bandwidth in different frequency bands, and can also include at least one irregular bandwidth in the same frequency band.

S402. The terminal device 110 accesses the cell through the initial standard bandwidth.

It should be noted that the initial standard bandwidth is between the initial BWP and the carrier bandwidth.

S403. gNB 410 receives a report from terminal device 110 as to whether it has the capability to support configuration greater than the irregular bandwidth.

S4041. When the terminal device 110 has the capability to support configuration greater than the carrier bandwidth, the gNB 410 configures the first standard bandwidth for the terminal device 110.

S4051. The terminal device 110 accesses the cell through the first standard bandwidth.

It should be noted that the first standard bandwidth is an adjacent standard bandwidth that is larger than the carrier bandwidth.

S4042. When the terminal device 110 does not have the capability to support configuration greater than the carrier bandwidth, gNB410 configures a second standard bandwidth for the terminal device 110.

S4052. The terminal device accesses the cell through the second standard bandwidth.

It should be noted that the second standard bandwidth is an adjacent standard bandwidth that is smaller than the carrier bandwidth.

FIG5 shows a flow chart of another method for configuring a terminal dedicated bandwidth provided by an embodiment of the present disclosure. The terminal dedicated bandwidth configuration method of this embodiment is applied to a terminal device, and includes:

S502: Receive the carrier bandwidth sent by the network device through broadcast information.

S504: Access the cell through the initial standard bandwidth according to the carrier bandwidth. The initial standard bandwidth here is the standard bandwidth actually used by the terminal device when accessing the cell this time.

S506: Report to the network device whether it has the capability to support configuration of a terminal-specific bandwidth greater than the carrier bandwidth.

S508: If the terminal has the capability to support configuration of a terminal-specific bandwidth greater than the carrier bandwidth, the terminal device is configured with a first standard bandwidth to access the cell through the network device, where the first standard bandwidth is greater than the irregular bandwidth.

In one embodiment, if the network device receives a signal from the terminal device that supports the configuration of a UE-specific CBW with a carrier bandwidth greater than that indicated by SIB1, the network device configures the first standard bandwidth of the terminal device, and the terminal device accesses the cell according to the first standard bandwidth, where the first standard bandwidth is greater than the carrier bandwidth. Thus, the network device can provide high-quality services to the terminal device and improve user experience without changing or upgrading the network device.

For the above S506, the carrier bandwidth includes irregular bandwidths of different frequency bands, and the frequency bands where the irregular bandwidths are located are reported, or the uplink and downlink transmission directions of the terminal device are reported. It should be noted that the disclosure does not specifically limit the manner of reporting terminal capabilities.

In some embodiments, the terminal-specific bandwidth configuration method also includes: if there is no ability to support the configuration of a terminal-specific bandwidth greater than the carrier bandwidth, there is no need to report to the network device whether there is the ability to support the configuration of a terminal-specific bandwidth greater than the carrier bandwidth, and the cell is accessed through the second standard bandwidth configured by the network device, and the second standard bandwidth is an adjacent standard bandwidth that is smaller than the carrier bandwidth.

In one embodiment, for a terminal device that does not have the ability to support configuration of a terminal-specific bandwidth that is greater than the carrier bandwidth, the terminal device can report to a network device that it does not have the ability to support a terminal-specific bandwidth that is greater than a non-standard bandwidth, and the network device configures a second standard bandwidth for the terminal device, where the second standard bandwidth is an adjacent standard bandwidth that is less than the carrier bandwidth.

When a terminal device accesses a cell through the initial standard bandwidth, the terminal device reports the above capability to the network device only if the terminal device has the capability to support the configuration of a terminal-specific bandwidth greater than the carrier bandwidth. For the terminal device that reports the capability, the network device determines that the terminal device can be configured with a terminal-specific CBW greater than the CBW indicated by SIB1 (i.e., the first standard bandwidth mentioned above). If the terminal device does not have the capability to support the configuration of a terminal-specific bandwidth greater than the carrier bandwidth, the network device defaults to the terminal device only supporting the configuration of a terminal-specific CBW included in the CBW indicated by SIB1 (i.e., the second standard bandwidth mentioned above). By means of optional reporting of capabilities, the bandwidth occupancy by data is reduced and the spectrum efficiency of irregular bandwidth is improved.

It should be noted that the terminal device may optionally report whether it has the capability to support the configuration of a terminal-specific bandwidth greater than the carrier bandwidth. In addition, it may also be implemented by setting a configuration identifier, for example, if the terminal device has the capability, the configuration identifier is set to 1, and if the terminal device does not have the capability, the configuration identifier is set to 0, so that the network device determines whether the terminal device has the capability according to the configuration identifier.

It should be noted that the terminal-specific bandwidth configuration method is executed in the same manner on the network device side and on the terminal device side, and the similarities are not repeated here.

A terminal dedicated bandwidth configuration method is provided in an embodiment of the present disclosure. The terminal device receives the carrier bandwidth sent by the network device through broadcast information, and accesses the cell through the initial standard bandwidth according to the 38.331 protocol.
