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

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

Alternatively, the wireless access network or wired network described above uses standard communication techniques and/or protocols. Network 120 is typically the internet, but may be any network including, but not limited to, a local area network (Local Area Network, LAN), metropolitan area network (Metropolitan Area Network, MAN), wide area network (Wide Area Network, WAN), a mobile, wired or wireless network, a private network, or any combination of virtual private networks. In some embodiments, data exchanged over the network is represented using techniques and/or formats including HyperText mark-up language (HTML), extensible markup language (extensible MarkupLanguage, XML), and the like. All or some of the links may also be encrypted using conventional encryption techniques such as secure sockets layer (Secure Socket Layer, SSL), transport layer security (Transport Layer Security, TLS), virtual private network (Virtual Private Network, VPN), internet protocol security (internet ProtocolSecurity, IPsec), etc. In other embodiments, custom and/or dedicated data communication techniques may also be used in place of or in addition to the data communication techniques described above.

It will be appreciated that for a wireless communication system, it is a network that provides wireless communication functionality. The communication system may employ different communication techniques 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. Networks may be classified into 2G (generation) networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks, 5G networks simply referred to as networks or systems, according to factors such as capacity, rate, delay, etc. of different networks. In the present disclosure, a radio access network includes a network device, which may be, for example, a radio access network entity; the core network comprises core network equipment. Wherein the radio access network entity may also become a base station. The radio access network may provide network services for the terminal device 110 through the network device, and different operators may provide different network services for the terminal device 110, and may also be understood that different operators correspond to different operator networks.

The terminal device 110, alternatively referred to as a terminal, user Equipment (UE), etc., may be various electronic devices including, but not limited to, a smart phone, a tablet computer, a laptop portable computer, a desktop computer, etc.

Alternatively, the clients of the applications installed in different terminal devices 110 are the same or clients of the same type of application based on different operating systems. The specific form of the application client may also be different based on the different terminal platforms, for example, the application client may be a mobile phone client, a PC client, etc.

Those skilled in the art will appreciate that the number of terminal devices 110, networks 120, and servers 130 in fig. 1 is merely illustrative, and that any number of terminal devices 110, networks 120, and servers 130 may be provided as desired. The embodiments of the present disclosure are not limited in this regard.

In the actual network deployment process, the 5G r17 standard does not define the carrier bandwidth in some 4G redrawn spectrum. For example, a certain communication carrier has a total spectrum bandwidth of 11MHz, such as an 800MHz band, of 824MHz to 835MHz or 869MHz to 880 MHz. However, in the current 5G standard, 11MHz is not defined, and these spectrum bandwidths are referred to as irregular bandwidths or as nonstandard bandwidths. In an 11MHz irregular bandwidth scenario, the related art is covered with a standard bandwidth of 10MHz, which is called smaller CBW (Channel Bandwidth ) scheme.

In 5G, a terminal specific bandwidth (UE-specific CBW) concept is introduced, which is used to indicate the bandwidth size and carrier position of the CBW of a specific terminal device, to support flexible use of spectrum by a user. Although the standard does not explicitly specify that the UE-specific CBW must be limited to BS (Base Station) CBW, in a normal scenario the UE-specific CBW is still contained in the CBW indicated in SIB 1. If the network device configures the terminal device with a UE-specific CBW that exceeds the CBW indicated in SIB1, the terminal device cannot guarantee normal operation.

For the case of irregular bandwidth, taking an irregular bandwidth of 11MHz as an example, under the smaller CBW scheme, only a carrier bandwidth of 10MHz can be used to cover the spectrum of 11 MHz. In the case of a subcarrier spacing of 15kHz (i.e., scs@15 kHz), the maximum number of physical resource blocks (Physic Resource Block, PRBs) available for a 10MHz carrier bandwidth is 52 PRBs, whereas in an irregular bandwidth scenario the maximum number of PRBs available for an 11MHz spectrum is 56 PRBs, it can be seen that in an irregular bandwidth scenario, a resource waste of 4 PRBs will be caused compared to a standard bandwidth scenario.

In the related art or standard, the 3gpp RAN4 conference discusses, for the irregular bandwidth SI, whether the terminal device supports a UE-specific CBW larger than the CBW indicated by SIB1, however, no consensus is reached.

Different manufacturers do not agree whether the terminal equipment can support the CBW indicated by the UE-specific CBW larger than SIB1, if all the terminal equipment is required to support, some terminal equipment cannot work normally, and if all the terminal equipment is not required to support, the waste of scarce spectrum resources is caused in an irregular bandwidth scene. How to reasonably utilize irregular bandwidth to improve the utilization rate of scarce spectrum resources becomes a problem to be solved.

Based on this, in the embodiment of the present disclosure, a method for configuring a dedicated bandwidth of a terminal is provided, where a network device issues an irregular bandwidth to the terminal through broadcasting information, the terminal accesses a cell through a first standard bandwidth slightly smaller than the irregular bandwidth according to 38.331 protocol, receives whether a capability of supporting configuring the dedicated bandwidth of the terminal greater than a carrier bandwidth reported by the terminal, if the terminal has the capability, configures a second standard bandwidth slightly greater than the irregular bandwidth for the terminal, and for an irregular bandwidth scenario, by introducing a terminal capability reporting mechanism, the network device configures the dedicated bandwidth of the terminal for the terminal according to the terminal capability, thereby improving the utilization rate of the irregular bandwidth, avoiding wasting scarce spectrum resources, and improving user experience.

The present exemplary embodiment will be described in detail below with reference to the accompanying drawings and examples.

First, in the embodiments of the present disclosure, a method for configuring a terminal-specific bandwidth is provided, which may be performed by any electronic device having computing processing capabilities. In some embodiments, the terminal-specific bandwidth configuration method provided in the embodiments of the present disclosure may be performed by a terminal device; in other embodiments, the terminal-specific bandwidth configuration method provided in the embodiments of the present disclosure may be performed by a network device, such as a base station; in other embodiments, the method for communication based on the CAG model provided in the embodiments of the present disclosure may also be implemented by the terminal device and the network device in an interactive manner.

Fig. 2 shows a flowchart of a method for configuring a terminal-specific bandwidth according to an embodiment of the present disclosure. As shown in fig. 2, the method for configuring the terminal-specific bandwidth provided in the embodiment of the present disclosure is applied to a network device, and includes:

S202, transmitting the carrier bandwidth to the terminal equipment through broadcasting information.

In one embodiment, as shown in fig. 3, the broadcast information may issue a carrier bandwidth to the terminal device in a system message block 1 (System Information Block, sib1), and the broadcast information may also issue an initial partial Bandwidth (BWP) in SIB 1. It should be noted that, the carrier bandwidth is represented by the maximum number of physical resource blocks that can be used by 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 the terminal equipment accesses the cell, whether the terminal equipment has the capability of supporting configuration of a terminal-specific bandwidth (UE-specific CBW) which is larger than the carrier bandwidth or not is received.

In some embodiments, the terminal device receives SIB1 issued by the network device (e.g., the gNB), and accesses the cell through an initial standard bandwidth according to the 38.331 protocol, where the initial standard bandwidth is a standard bandwidth actually adopted by the terminal device when the terminal device accesses the cell at this time. For example, if the carrier bandwidth in SIB1 is configured to be 56PRB (corresponding to an irregular bandwidth of 11 MHz), the initial BWP is configured to be 52PRB, and the terminal device determines a standard bandwidth, such as 10MHz, between which transmission can be performed, according to the description of 38.331 protocol, and accesses the cell through the 10MHz standard bandwidth.

Under the condition of establishing communication between the terminal equipment and the network equipment, the terminal equipment can adopt various methods to realize reporting whether the terminal equipment has the capability of supporting the configuration of the terminal special bandwidth which is larger than the carrier bandwidth, so that the network equipment configures the corresponding standard bandwidth according to the capability of the terminal equipment.

For example, the terminal device sends the capability information to the network device through an RRC connection setup complete message; the method can also be transmitted to the network equipment by transmitting an Attach message carrying the capability information; the capability information may also be sent to the network device by sending a TAU request message, a service request message, or a dedicated capability report message carrying the capability message.

In one embodiment, the above-mentioned ability of the terminal device is optionally reported, and for the terminal device without the above-mentioned ability, reporting is not needed; and reporting the capability to the terminal equipment with the capability.

In some embodiments, the above-mentioned capabilities of the terminal device are optionally reported. For example, the capability identifier may be used to indicate whether the terminal device has a capability to support configuring a terminal-specific bandwidth that is greater than the carrier bandwidth, and the capability identifier may be represented by a number, a letter, a symbol, or the like. Illustratively, the capability identification employs 0 to indicate that the terminal device does not have the capability to support configuring a terminal-specific bandwidth that is greater than the carrier bandwidth, and the capability identification employs 1 to indicate that the terminal device has the capability to support configuring a terminal-specific bandwidth that is greater than the carrier bandwidth.

It should be noted that, the reporting manner and reporting content of the above-mentioned capability of the terminal device may be determined according to the actual situation.

S206, if the terminal equipment has the capability of supporting the configuration of the terminal special bandwidth which is larger than the carrier bandwidth, the first standard bandwidth is configured for the terminal equipment, and the first standard bandwidth is larger than the carrier bandwidth.

In one embodiment, if the network device receives the capability of supporting the UE-specific CBW configured with the carrier bandwidth indicated by SIB1 sent by the terminal device, the network device configures a 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 an adjacent standard bandwidth greater than the carrier bandwidth, thereby providing a high-quality service for the terminal device without changing or upgrading the network device, and improving user experience.

For example, the network device may carry the first standard bandwidth information in dedicated messages sent to the UE after determining that the terminal device has the capability to support UE-specific CBW configured with a carrier bandwidth greater than the SIB1 indication, the dedicated messages including: RRC connection setup message, attach accept message, or RRC reconfiguration message, etc.

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

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

According to the terminal dedicated bandwidth configuration method provided by the embodiment of the disclosure, the network equipment issues the carrier bandwidth to the terminal equipment through the broadcast information, the terminal equipment accesses the cell through the initial standard bandwidth according to 38.331 protocol, whether the terminal equipment has the capability of supporting the configuration of the terminal dedicated bandwidth larger than the carrier bandwidth or not is received, if the terminal equipment has the capability, the first standard bandwidth slightly larger than the irregular bandwidth is configured for the terminal equipment, and for the irregular bandwidth scene, the network equipment configures the terminal dedicated bandwidth for the terminal equipment according to the terminal capability report by introducing the terminal capability report mechanism, so that the utilization rate of the irregular bandwidth is improved, the waste of scarce spectrum resources is avoided, and the user experience is improved.

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 bandwidths and maximum PRB number

Irregular bandwidth/MHz	6	7	11	12	13
						Maximum number of PRBs/PRB	29	35	56	62	67

In one embodiment, the maximum number of physical resource blocks that can be used by the irregular bandwidth is obtained by: determining an adjacent standard bandwidth of the irregular bandwidth, wherein the adjacent standard bandwidth comprises an adjacent standard bandwidth greater than the irregular bandwidth or the adjacent standard bandwidth comprises an adjacent standard bandwidth less than the irregular bandwidth; and determining the maximum number of physical resource blocks which can be used by the irregular bandwidth according to the guard bands adjacent to the standard bandwidth.

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

And adopting Guard bands (Guard bands) adjacent to the standard bandwidths to meet the requirement of the first standard bandwidth of the terminal equipment, and determining the maximum PRB number which can be used by the irregular bandwidths according to the Guard bands.

In one embodiment, for a terminal device not reporting a capability of supporting a terminal-specific bandwidth configured to be greater than the carrier bandwidth indicated by SIB1, or for a network device receiving a capability of the terminal device reporting a terminal-specific bandwidth not supporting a carrier bandwidth configured to be greater than the carrier bandwidth indicated by SIB1, determining that the terminal device supports configuration of a second standard bandwidth, where the second standard bandwidth is less than the carrier bandwidth. It should be noted that the second standard bandwidth is a contiguous standard bandwidth smaller than the carrier bandwidth.

Illustratively, when the terminal device does not have the capability to support a terminal-specific bandwidth that is greater than the carrier bandwidth indicated by SIB1, the terminal device is serviced with a second standard bandwidth that is slightly less than the carrier bandwidth. For example, for a carrier bandwidth of 11MHz, the second standard bandwidth may be covered with 10 MHz.

According to the terminal special bandwidth configuration method provided by the embodiment of the disclosure, the network equipment transmits the irregular bandwidth to the terminal equipment through the broadcast information, the terminal equipment accesses the cell through the first standard bandwidth which is slightly smaller than the irregular bandwidth according to 38.331 protocol, whether the terminal equipment has the capability of supporting the configuration of the terminal special bandwidth which is larger than the carrier bandwidth or not is received, if the terminal equipment does not have the capability, the terminal equipment is configured with the second standard bandwidth which is slightly smaller than the irregular bandwidth, and for the irregular bandwidth scene, the network equipment is enabled to report the terminal special bandwidth configured for the terminal equipment according to the terminal capability by introducing the terminal capability reporting mechanism, so that the utilization rate of the irregular bandwidth is improved, the waste of scarce spectrum resources is avoided, and the user experience is improved.

To enhance the understanding of the above embodiment, the following is a detailed description with reference to fig. 4.

As shown in fig. 4, a method for configuring a dedicated bandwidth of a terminal mainly includes the following steps:

s401, the gNB 410 issues the carrier bandwidth to the terminal device 110 through the broadcast information.

It should be noted that, the broadcast information may issue a carrier bandwidth to the terminal device in the system message block 1SIB1, or issue an initial BWP to the terminal device in SIB1, where the carrier bandwidth is greater than the initial BWP; the carrier bandwidth may include at least one irregular bandwidth of different frequency bands, or may include at least one irregular bandwidth of 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, the gNB 410 receives whether the capability of supporting configuration greater than the irregular bandwidth reported by the terminal device 110.

S4041, in the case where the terminal device 110 has the capability of supporting configuration larger 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 greater than the carrier bandwidth.

S4042, in the case that the terminal device 110 does not have the capability of supporting configuration larger than the carrier bandwidth, the gNB 410 configures the terminal device 110 with the second standard bandwidth.

S4052, the terminal equipment accesses the cell through the second standard bandwidth.

It should be noted that the second standard bandwidth is a contiguous standard bandwidth smaller than the carrier bandwidth.

Fig. 5 shows a flowchart of yet another method for configuring a terminal-specific bandwidth according to an embodiment of the present disclosure. As shown in fig. 5, the terminal-specific bandwidth configuration method of the present embodiment is applied to a terminal device, and includes:

S502, receiving carrier bandwidth issued by the network equipment through the broadcast information.

S504, accessing the cell through the initial standard bandwidth according to the carrier bandwidth. The initial standard bandwidth here is the standard bandwidth actually adopted by the terminal device when the terminal device accesses the cell at this time.

S506, reporting whether the network equipment has the capability of supporting configuration of the terminal special bandwidth which is larger than the carrier bandwidth.

S508, if the capability of supporting the configuration of the terminal special bandwidth larger than the carrier bandwidth is provided, accessing the cell through the first standard bandwidth configured by the network equipment for the terminal equipment, wherein the first standard bandwidth is larger than the irregular bandwidth.

In one embodiment, if the network device receives the capability of supporting the UE-specific CBW configured with the carrier bandwidth indicated by SIB1 sent by the terminal device, the network device configures a 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, so that high-quality service can be provided for the terminal device without changing or upgrading the network device, and user experience is improved.

For S506 above, the carrier bandwidth includes irregular bandwidths of different frequency bands, and reports to the frequency band where each irregular bandwidth is located, or reports to the uplink and downlink transmission directions of the terminal device. It should be noted that, the disclosure is not limited specifically to the manner of reporting the terminal capability.

In some embodiments, the terminal-specific bandwidth configuration method further includes: if the capability of supporting the terminal special bandwidth configured to be greater than the carrier bandwidth is not available, whether the capability of supporting the terminal special bandwidth configured to be greater than the carrier bandwidth is available or not is not required to be reported to the network equipment, the cell is accessed through a second standard bandwidth configured by the network equipment, and the second standard bandwidth is an adjacent standard bandwidth smaller than the carrier bandwidth.

In one embodiment, for a terminal device that does not have the capability to support a terminal-specific bandwidth configured to be greater than the carrier bandwidth, the terminal device may report to the network device that does not have the capability to support a terminal-specific bandwidth configured to be greater than the non-standard bandwidth, where 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.
