[0087] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0088] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0089] The technical solution provided in the embodiments of the present application can be applicable to a variety of systems, such as a 5G system.

[0090] Among them, the terminal involved in the embodiment of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal may also be different. For example, in a 5G system, the terminal may be called a user equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a wireless access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs) and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, and a user device, but is not limited in the embodiments of the present application.

[0091] The network device involved in the embodiment of the present application may be a base station, which may include multiple cells providing services for the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, and serve as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (Global System for Mobile communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (evolutional Node B, eNB or e-NodeB) in the long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (Home evolved Node B, HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., which is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0092] For example, in an embodiment of the present application, one or more antennas may be used between the network device and the terminal device for multiple input multiple output (MIMO) transmission, and the MIMO transmission may be single user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of the antenna combination, the MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it may be diversity transmission, precoded transmission or beamforming transmission, etc.

[0093] 3GPP has proposed the Reduced Capability (RedCap) technology. Before a RedCap terminal transmits data, a base station will configure a RedCap dedicated bandwidth part (Bandwidth Part, BWP) for it.

[0094] During the initial access phase of the RedCap terminal, the base station will configure an independent initial access BWP for the RedCap terminal. After the RedCap terminal accesses, the base station needs to configure a RedCap-specific BWP for it. For the base station, when configuring a RedCap-specific BWP for the RedCap terminal, it is not only necessary to allocate resources such as the Physical Downlink Shared Channel (PDSCH) and the Physical Uplink Shared Channel (PUSCH) for the RedCap terminal on the RedCap-specific BWP, but also to allocate public channel resources for the RedCap terminal. Therefore, it is crucial to reasonably configure a RedCap-specific BWP for the RedCap terminal.

[0095] However, the relevant prior art does not provide a technical solution for how the base station configures a RedCap-specific BWP for a RedCap terminal. Therefore, how to reasonably configure a RedCap-specific BWP for a RedCap terminal to improve the utilization of frequency band resources is a technical problem that needs to be urgently solved by those skilled in the art.

[0096] In order to reasonably configure a RedCap dedicated BWP for a RedCap terminal, an embodiment of the present application provides a method for configuring a RedCap dedicated partial bandwidth BWP. When a RedCap terminal expects to access a serving cell, a target RedCap dedicated BWP that accommodates the RedCap terminal is determined based on whether there is a configured RedCap dedicated BWP in the serving cell, and a target RedCap dedicated BWP is configured for the RedCap terminal. The target RedCap dedicated BWP is used for data transmission by the first RedCap terminal. In this way, based on whether there is a configured RedCap dedicated BWP in the serving cell, a target RedCap dedicated BWP for data transmission can be reasonably configured for the RedCap terminal, thereby effectively improving the utilization rate of frequency band resources.

[0097] Below, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0098] Figure 1 A flowchart of a method for configuring a RedCap dedicated bandwidth BWP provided in an embodiment of the present application Figure 1 The configuration method of the RedCap dedicated part bandwidth BWP can be applied to network devices. For example, see Figure 1 As shown, the configuration method of the RedCap dedicated bandwidth BWP may include:

[0099] S101. When a first RedCap terminal desires to access a serving cell, a target RedCap dedicated BWP for accommodating the first RedCap terminal is determined according to whether a first RedCap dedicated BWP is currently configured in the serving cell.

[0100] The target RedCap dedicated BWP is a RedCap dedicated BWP used by the first RedCap terminal for data transmission.

[0101] For example, in an embodiment of the present application, the first RedCap terminal expects to access the service cell, which may include at least two situations. One situation is that the first RedCap terminal expects to newly access the service cell, and the other situation is that the first RedCap terminal expects to switch to the service cell from other service cells.

[0102] For example, in the embodiment of the present application, when determining the target RedCap dedicated BWP according to whether there is a configured first RedCap dedicated BWP in the serving cell, the following two scenarios may be included:

[0103] In one scenario, if the first RedCap dedicated BWP does not currently exist in the serving cell, that is, the serving cell has not currently configured a RedCap dedicated BWP, it is necessary to create a new target RedCap dedicated BWP for the first RedCap terminal to configure the target RedCap dedicated BWP for the first RedCap terminal.

[0104] For example, when a target RedCap dedicated BWP is newly created for the first RedCap terminal, the BWP of the highest frequency band or the BWP of the lowest frequency band in the serving cell can be newly created as the target RedCap dedicated BWP to configure the target RedCap dedicated BWP for the first RedCap terminal.

[0105] When a new target RedCap dedicated BWP is created for the first RedCap terminal, it is taken into account that the new target RedCap dedicated BWP will occupy certain channel resources, resulting in discontinuity of service channel resources. Therefore, in order to ensure the continuity of service channel resources and thus improve the utilization rate of channel resources, in an embodiment of the present application, the BWP of the highest frequency band can be determined from the service cell, and the BWP of the highest frequency band can be newly created as the target RedCap dedicated BWP; or, the BWP of the lowest frequency band can be determined from the service cell, and the BWP of the lowest frequency band can be newly created as the target RedCap dedicated BWP. In this way, starting from the BWP of the highest frequency band or the BWP of the lowest frequency band in the service cell, a new RedCap dedicated BWP is created, which can ensure that the BWPs of other frequency bands are continuous BWPs. In this way, continuous channel resources can be allocated to conventional type terminals, thereby effectively ensuring the continuity of service channel resources and improving the utilization rate of channel resources.

[0106] In actual application, for a service cell with 100M bandwidth, up to 5 RedCap dedicated BWPs can be configured. For example, see Figure 2 As shown, Figure 2A schematic diagram of a 100M bandwidth and corresponding BWP is provided for an embodiment of the present application. The 5 BWPs included in the 100M bandwidth are, in descending order of frequency band: BWP1, BWP2, BWP3, BWP4, and BWP5. When a new target RedCap dedicated BWP is created for the first RedCap terminal, BWP1 of the highest frequency band can be newly created as the target RedCap dedicated BWP. This not only configures the target RedCap dedicated BWP for the first RedCap terminal, but also ensures that the BWPs of other frequency bands are continuous BWPs. This allows continuous channel resources to be allocated to conventional type terminals, thereby effectively ensuring the continuity of service channel resources and improving the utilization of channel resources.

[0107] Alternatively, when creating a new target RedCap dedicated BWP for the first RedCap terminal, the BWP5 of the lowest frequency band can also be newly created as the target RedCap dedicated BWP. This not only configures the target RedCap dedicated BWP for the first RedCap terminal, but also ensures that the BWPs of other frequency bands are continuous BWPs. This allows continuous channel resources to be allocated to conventional type terminals, thereby effectively ensuring the continuity of service channel resources and improving the utilization rate of channel resources.

[0108] Combined with the above Figure 2 As shown, it can be understood that, assuming that BWP1 of the highest frequency band is newly built as a RedCap dedicated BWP for the first time, when a RedCap dedicated BWP is newly built later, BWP2 of the second highest frequency band can be newly built as a RedCap dedicated BWP in the order of frequency bands from high to low, and so on. On the contrary, assuming that BWP5 of the lowest frequency band is newly built as a RedCap dedicated BWP for the first time, when a RedCap dedicated BWP is newly built later, BWP4 of the second lowest frequency band can be newly built as a RedCap dedicated BWP in the order of frequency bands from low to high, and so on.

[0109] It can be seen that when creating a new RedCap dedicated BWP, starting from one end of the bandwidth, BWPs are selected in sequence in the order of frequency band from high to low to be newly created as RedCap dedicated BWPs; or, BWPs are selected in sequence in the order of frequency band from low to high to be newly created as RedCap dedicated BWPs. This not only configures a RedCap dedicated BWP for the RedCap terminal, but also ensures that the BWPs of other frequency bands are continuous BWPs. This allows continuous channel resources to be allocated to conventional terminals, thereby effectively ensuring the continuity of service channel resources and improving the utilization of channel resources.

[0110] In addition, when creating a new RedCap dedicated BWP, you can also select BWPs from both ends of the bandwidth for configuration. For example, first create a new BWP for RedCap in the highest frequency band, then create a new BWP for RedCap in the lowest frequency band, then create a new BWP for RedCap in the second highest frequency band, then create a new BWP for RedCap in the second lowest frequency band, and so on. For example, see Figure 3 As shown, Figure 3 A schematic diagram of another 100M bandwidth and corresponding BWP provided in an embodiment of the present application, when a new RedCap dedicated BWP is created for the first time, the highest BWP1 can be newly created as a RedCap dedicated BWP; when a new RedCap dedicated BWP is created for the second time, the lowest BWP2 can be newly created as a RedCap dedicated BWP; when a new RedCap dedicated BWP is created for the third time, the second highest BWP3 can be newly created as a RedCap dedicated BWP; when a new RedCap dedicated BWP is created for the fourth time, the second lowest BWP4 can be newly created as a RedCap dedicated BWP, etc. Alternatively, the BWP of the lowest frequency band is first newly created as a RedCap dedicated BWP, and then the BWP of the highest frequency band is newly created as a RedCap dedicated BWP, and then the BWP of the second lowest frequency band is newly created as a RedCap dedicated BWP, and then the BWP of the second highest frequency band is newly created as a RedCap dedicated BWP, etc., which can be set according to actual needs.

[0111] It is not difficult to see that the above-mentioned method of selecting BWP from both ends of the bandwidth to configure the RedCap dedicated BWP can not only configure the RedCap dedicated BWP for the RedCap terminal, but also ensure that the BWP of other frequency bands is a continuous BWP. In this way, continuous channel resources can be allocated to conventional terminals, thereby effectively ensuring the continuity of service channel resources and improving the utilization rate of channel resources.

[0112] In another scenario, if there is currently a first RedCap dedicated BWP in the service cell, that is, the service cell is currently configured with a RedCap dedicated BWP, the target RedCap dedicated BWP can be determined based on the relevant value of the first RedCap dedicated BWP to configure the target RedCap dedicated BWP for the first RedCap terminal.

[0113] The relevant values ​​include the number of accommodated second RedCap terminals and / or channel utilization.

[0114] After determining the target RedCap dedicated BWP to accommodate the first RedCap terminal through the above S101, the target RedCap dedicated BWP can be configured for the first RedCap terminal, that is, the following S102 is executed to enable the first RedCap terminal to perform data transmission based on the target RedCap dedicated BWP.

[0115] S102. Configure a target RedCap-specific BWP for the first RedCap terminal.

[0116] It can be seen that in the embodiment of the present application, when the first RedCap terminal expects to access the serving cell, the target RedCap dedicated BWP for accommodating the first RedCap terminal is determined according to whether there is a configured first RedCap dedicated BWP in the serving cell; the target RedCap dedicated BWP is configured for the first RedCap terminal, and the target RedCap dedicated BWP is used for data transmission by the first RedCap terminal. In this way, according to whether there is a configured RedCap dedicated BWP in the serving cell, the target RedCap dedicated BWP for data transmission can be reasonably configured for the RedCap terminal, thereby effectively improving the utilization rate of the frequency band resources.

[0117] Based on the above Figure 1 In the embodiment shown, in order to facilitate understanding of how to determine the target RedCap dedicated BWP according to the relevant value of the first RedCap dedicated BWP in the above S101, the following will describe in detail how to determine the target RedCap dedicated BWP according to the relevant value of the first RedCap dedicated BWP, with the relevant value being the number of second RedCap terminals accommodated and the relevant value being the channel utilization rate.

[0118] When the relevant value is the number of the second RedCap terminals that have been accommodated, the corresponding first relevant value is the equilibrium value of the number of RedCap terminals that can be accommodated, and the second relevant value is the maximum number of RedCap terminals that can be accommodated. For example, see Figure 4 As shown, Figure 4 A flowchart of a method for determining a target RedCap dedicated BWP according to the number of second RedCap terminals accommodated by a first RedCap dedicated BWP is provided in an embodiment of the present application. The determination method can be applied to a network device. For example, see Figure 4 As shown, the determination method may include:

[0119] S401. Determine whether the number of second RedCap terminals accommodated in the first RedCap dedicated BWP is less than a balance value of the number of RedCap terminals that can be accommodated.

[0120] The second RedCap terminal is a RedCap terminal that has been accommodated in the first RedCap dedicated BWP, that is, the second RedCap terminal can perform data transmission through the configured first RedCap dedicated BWP.

[0121] For example, the equilibrium value of the number of RedCap terminals that can be accommodated can be recorded as N UE1 The maximum number of RedCap terminals that can be accommodated can be recorded as N UEmax For RedCap-only BWP, the number of RedCap terminals it accommodates is N UE1 The maximum number of RedCap terminals that can be accommodated is N. UEmax .

[0122] It should be noted that the number of RedCap terminals that can be accommodated is N UEmax The setting is related to the actual application scenario, such as the type of RedCap terminal, bandwidth and other factors, which can be set according to actual needs. For example, in the video surveillance scenario, the general rate requirement is 3-4Mbps. For the frequency-division duplex (FDD) system, the number of RedCap terminals that can be accommodated by a RedCap dedicated BWP is N. UEmax It can be taken as 20. For the time-division duplex (TDD) system, in the case of 1D3U time slot configuration, the number of RedCap terminals that can be accommodated is N UEmax It can be set to 10, and other time slot configurations will be less than 10.

[0123] In the embodiment of the present application, in order to avoid excessive number of RedCap terminals on the RedCap dedicated BWP causing network congestion and affecting the total throughput, a balance value N of the number of RedCap terminals that can be accommodated can be set. UE1 The maximum number of RedCap terminals that can be accommodated is N UEmax The relationship is:

[0124] N UE1 =N UEmax ×η1

[0125] Among them, η1 represents the percentage of resource-balanced terminals in the dimension of the number of RedCap terminals that can be accommodated. The value of η1 can be configured according to the expected resource occupancy rate. For example, for industrial sensors and wearable device scenarios, the uplink rate requirement will be smaller than that of video surveillance scenarios. UEmax The value of N is larger and needs to be calculated according to the rate requirements. UEmaxThe value of can be based on the fact that the RedCap dedicated BWP can accommodate 80-90% of the theoretical value of the RedCap terminal service rate, and the value of η1 can be 60%, which can be set according to actual needs.

[0126] After judgment, when the number of second RedCap terminals accommodated by the first RedCap dedicated BWP is less than the balance value of the number of RedCap terminals that can be accommodated, it means that the first RedCap dedicated BWP can continue to accommodate RedCap terminals. Therefore, the first RedCap dedicated BWP can be directly determined as the target RedCap dedicated BWP to configure the first RedCap dedicated BWP for the first RedCap terminal, and execute the following S402. When the number of second RedCap terminals accommodated by the first RedCap dedicated BWP is greater than or equal to the balance value of the number of RedCap terminals that can be accommodated, it means that the RedCap terminals accommodated on the first RedCap dedicated BWP have reached the resource balance value, and it is necessary to further judge whether the service cell can build a new second RedCap dedicated BWP, and determine the target RedCap dedicated BWP according to the judgment result, and execute the following S403.

[0127] S402. Determine the first RedCap dedicated BWP as the target RedCap dedicated BWP.

[0128] S403: Determine whether the serving cell can newly establish a second RedCap dedicated BWP, and determine a target RedCap dedicated BWP according to the determination result.

[0129] For example, when determining the target RedCap dedicated BWP according to the judgment result, two cases may be included:

[0130] In one case, the judgment result indicates that a second RedCap dedicated BWP can be newly created.

[0131] In this case, since a second RedCap dedicated BWP can be newly built, the second RedCap dedicated BWP can be directly newly built, and the newly built second RedCap dedicated BWP can be determined as the target RedCap dedicated BWP. This not only can allocate the target RedCap dedicated BWP to the first RedCap terminal, but also will not affect the service rate of the RedCap terminal on the existing first RedCap dedicated BWP.

[0132] In another case, the determination result indicates that a second RedCap dedicated BWP cannot be newly created.

[0133] In this case, since a new second RedCap dedicated BWP cannot be created, in order to allocate a target RedCap dedicated BWP to the first RedCap terminal, it can only be determined whether the number of second RedCap terminals accommodated by the established first RedCap dedicated BWP is less than the maximum number of RedCap terminals N accommodated. UEmax , if it is greater than or equal to the maximum number of RedCap terminals N that can be accommodated UEmax , then the first RedCap terminal fails to accept.

[0134] On the contrary, if it is less than the maximum number of RedCap terminals N that can be accommodated UEmax , indicating that the first RedCap dedicated BWP has reached the equilibrium value N of the number of RedCap terminals that can be accommodated. UE1 , but the maximum number of RedCap terminals N that can be accommodated has not been reached UEmax , there is still a certain amount of accommodating space, therefore, the first RedCap dedicated BWP can be used as the target RedCap dedicated BWP to configure the target RedCap dedicated BWP for the first RedCap terminal.

[0135] It can be seen that in the embodiment of the present application, when determining the target RedCap dedicated BWP according to the number of second RedCap terminals accommodated by the first RedCap dedicated BWP, if the number of second RedCap terminals accommodated by the first RedCap dedicated BWP is less than the balance value N of the number of RedCap terminals that can be accommodated, UE1 , indicating that the first RedCap dedicated BWP can continue to accommodate RedCap terminals, the first RedCap dedicated BWP can be determined as the target RedCap dedicated BWP; if the number of second RedCap terminals accommodated by the first RedCap dedicated BWP is greater than or equal to the balance value N of the number of RedCap terminals that can be accommodated UE1 , it is determined whether the serving cell can build a second RedCap dedicated BWP, and the target RedCap dedicated BWP is determined according to the determination result, so that the target RedCap dedicated BWP for data transmission can be reasonably configured for the RedCap terminal, thereby effectively improving the utilization rate of frequency band resources.

[0136] Based on the above Figure 4 In the embodiment shown, when the relevant value is the number of the second RedCap terminals that have been accommodated, it can be further determined whether the number of the second RedCap terminals that have been accommodated in the RedCap dedicated BWP configured in the serving cell is greater than the balance value N of the number of RedCap terminals that can be accommodated. UE1The third RedCap dedicated BWP, and whether there is a balance value of the number of RedCap terminals that can be accommodated is less than the balance value N of the number of RedCap terminals that can be accommodated UE1 If there is no third RedCap dedicated BWP and / or fourth RedCap dedicated BWP, RedCap dedicated BWP balancing cannot be performed; if there is a third RedCap dedicated BWP and a fourth RedCap dedicated BWP, some RedCap terminals accommodated by the third RedCap dedicated BWP can be reconfigured to the fourth RedCap dedicated BWP. In this way, through RedCap dedicated BWP balancing, not only can the fourth RedCap dedicated BWP be reconfigured for some RedCap terminals, but also the service rate of the RedCap terminals on the third RedCap dedicated BWP can be met.

[0137] Above Figure 4 The embodiment shown describes in detail the technical solution of how to determine the target RedCap dedicated BWP according to the number of second RedCap terminals accommodated by the first RedCap dedicated BWP when the relevant value is the number of second RedCap terminals accommodated. Below, the technical solution of how to determine the target RedCap dedicated BWP according to the number of second RedCap terminals accommodated by the first RedCap dedicated BWP when the relevant value is the channel utilization will be described in detail.

[0138] When the correlation value is the channel utilization rate, the corresponding first correlation value is the channel utilization rate equilibrium value, and the second correlation value is the channel utilization rate maximum value. Figure 5 As shown, Figure 5 The present invention provides a flow chart of a method for determining a target RedCap dedicated BWP according to the channel utilization of a first RedCap according to an embodiment of the present invention. The determination method can be applied to a network device. For example, see Figure 5 As shown, the determination method may include:

[0139] S501. Determine whether the channel utilization of the first RedCap dedicated BWP is less than the channel utilization balance value.

[0140] For example, the channel utilization balance value can be recorded as M equa , the maximum channel utilization can be recorded as M max For RedCap dedicated BWP, its channel utilization balance value M equa Does not exceed the maximum channel utilization M max .

[0141] It is also necessary to explain that the channel utilization rate equalization value M equaThe settings are related to the actual application scenario, for example, the type of RedCap terminal, bandwidth and other factors, and can be set according to actual needs.

[0142] In the embodiment of the present application, in order to avoid excessive number of RedCap terminals on the RedCap dedicated BWP causing network congestion and affecting the total throughput, the channel utilization balance value M can be set. equa and the maximum channel utilization M max The relationship is:

[0143] M equa =M max ×η2

[0144] Wherein, η2 represents the percentage of the number of resource-balanced terminals in the dimension of channel utilization, and the value of η2 can be configured according to the desired resource occupancy rate.

[0145] For example, in the embodiment of the present application, the maximum channel utilization M is determined max When the uplink channel utilization rate and the downlink channel utilization rate are used as the basis for the RedCap terminal equalization on the RedCap dedicated BWP, the maximum channel utilization rate M can be determined. max For example, the maximum channel utilization M is determined by using the uplink channel utilization and the downlink channel utilization. max When the uplink channel utilization rate needs to be determined separately, it can be recorded as M PUSCH , the RedCap terminal has a single uplink stream, and the uplink channel utilization rate of a RedCap dedicated BWP is M PUSCH The calculation of can be seen as follows:

[0146]

[0147] The RedCap terminal has two downstream flows, and the downstream channel utilization rate of a RedCap dedicated BWP is M. PDSCH The calculation of can be seen as follows:

[0148]

[0149] Among them, the values ​​of the actual air split flow number and the typical air split flow number can be set according to actual needs, and the embodiments of the present application do not make specific limitations here.

[0150] Maximum channel utilization on RedCap dedicated BWP M max The uplink channel utilization M of the RedCap dedicated BWP can be obtained PUSCH and downlink channel utilization M PDSCH The larger of the two, namely M max =(M PUSCH ,M PDSCH), thereby determining the maximum channel utilization M on the RedCap dedicated BWP max .

[0151] After judgment, when the channel utilization rate of the first RedCap dedicated BWP is less than the channel utilization rate equilibrium value, it means that the first RedCap dedicated BWP can continue to accommodate RedCap terminals. Therefore, the first RedCap dedicated BWP can be directly determined as the target RedCap dedicated BWP to configure the first RedCap terminal, and execute the following S502. When the channel utilization rate of the first RedCap dedicated BWP is greater than or equal to the channel utilization rate equilibrium value, it means that the RedCap terminals accommodated on the first RedCap dedicated BWP have reached the resource equilibrium value, and it is necessary to further judge whether the service cell can build a new second RedCap dedicated BWP, and determine the target RedCap dedicated BWP according to the judgment result, and execute the following S503.

[0152] S502. Determine the first RedCap dedicated BWP as the target RedCap dedicated BWP.

[0153] S503: Determine whether the serving cell can newly establish a second RedCap dedicated BWP, and determine a target RedCap dedicated BWP according to the determination result.

[0154] For example, when determining the target RedCap dedicated BWP according to the judgment result, two cases may be included:

[0155] In one case, the judgment result indicates that a second RedCap dedicated BWP can be newly created.

[0156] In this case, since a second RedCap dedicated BWP can be newly built, the second RedCap dedicated BWP can be directly newly built, and the newly built second RedCap dedicated BWP can be determined as the target RedCap dedicated BWP. This not only can allocate the target RedCap dedicated BWP to the first RedCap terminal, but also will not affect the service rate of the RedCap terminal on the existing first RedCap dedicated BWP.

[0157] In another case, the determination result indicates that a second RedCap dedicated BWP cannot be newly created.

[0158] In this case, since a new second RedCap dedicated BWP cannot be created, in order to allocate a target RedCap dedicated BWP to the first RedCap terminal, it is only necessary to determine whether the channel utilization rate of the established first RedCap dedicated BWP is less than the maximum channel utilization rate M. max , if it is greater than or equal to the maximum channel utilization Mmax , then the first RedCap terminal fails to accept.

[0159] On the contrary, if it is less than the maximum channel utilization M max , indicating that the first RedCap dedicated BWP has reached the channel utilization balance value M equa , but the maximum channel utilization M is not reached max , there is still a certain amount of accommodating space, therefore, the first RedCap dedicated BWP can be used as the target RedCap dedicated BWP to configure the target RedCap dedicated BWP for the first RedCap terminal.

[0160] It can be seen that in the embodiment of the present application, when determining the target RedCap dedicated BWP according to the number of second RedCap terminals accommodated by the first RedCap dedicated BWP, if the channel utilization rate of the first RedCap dedicated BWP is less than the channel utilization rate balance value M equa , indicating that the first RedCap dedicated BWP can still accommodate the RedCap terminal, then the first RedCap dedicated BWP can be determined as the target RedCap dedicated BWP; if the channel utilization rate of the first RedCap dedicated BWP is greater than or equal to the channel utilization rate balance value M equa , it is determined whether the serving cell can build a second RedCap dedicated BWP, and the target RedCap dedicated BWP is determined according to the determination result, so that the target RedCap dedicated BWP for data transmission can be reasonably configured for the RedCap terminal, thereby effectively improving the utilization rate of frequency band resources.

[0161] Based on the above Figure 5 In the embodiment shown, when the relevant value is the channel utilization rate, it is also possible to further determine whether there is a channel utilization rate greater than the channel utilization rate balance value M in the RedCap dedicated BWP configured in the serving cell. equa The third RedCap dedicated BWP, and whether there is a channel utilization less than the channel utilization equalization value M equa If there is no third RedCap dedicated BWP and / or fourth RedCap dedicated BWP, RedCap dedicated BWP balancing cannot be performed; if there is a third RedCap dedicated BWP and a fourth RedCap dedicated BWP, some RedCap terminals accommodated by the third RedCap dedicated BWP can be reconfigured to the fourth RedCap dedicated BWP. In this way, through RedCap dedicated BWP balancing, not only can the fourth RedCap dedicated BWP be reconfigured for some RedCap terminals, but also the service rate of the RedCap terminals on the third RedCap dedicated BWP can be met.

[0162] It can be understood that, for the above-mentioned RedCap dedicated BWP balancing scheme, the RedCap dedicated BWP balancing judgment can be performed when the RedCap terminal expects to newly access the service cell, or, the RedCap dedicated BWP balancing judgment can be performed when the RedCap terminal expects to access the service cell from other service cells; or, the RedCap dedicated BWP balancing judgment can be performed, and after the RedCap terminals on a certain RedCap dedicated BWP gradually release the connection, there will be some RedCap dedicated BWPs with fewer RedCap terminals and other RedCap dedicated BWPs with more RedCap terminals. The specific settings can be made according to actual needs, so as to reasonably configure the RedCap terminal with a target RedCap dedicated BWP for data transmission, thereby improving the utilization rate of frequency band resources.

[0163] Based on any of the above embodiments, after configuring the target RedCap dedicated BWP to the first RedCap terminal, relatively idle RedCap dedicated BWPs can be proactively sorted out. Figure 6 As shown, Figure 6 A flowchart of a method for arranging relatively idle RedCap dedicated BWPs provided in an embodiment of the present application, the method may include:

[0164] S601. Determine the first number of RedCap dedicated BWPs to be configured according to the number of RedCap terminals in the serving cell and the preset accommodation number.

[0165] In order to ensure the service rate of the RedCap terminal on the RedCap dedicated BWP, for example, in the embodiment of the present application, the preset accommodation quantity can be the balance value N of the number of RedCap terminals that can be accommodated. UE1 .

[0166] For example, in the embodiment of the present application, according to A first number of RedCap-specific BWPs that should be configured is determined.

[0167] Among them, N BWP Indicates the first number of RedCap dedicated BWPs to be configured, N RedCap Indicates the number of RedCap terminals in the service cell.

[0168] After determining the first number of RedCap dedicated BWPs that should be configured in the serving cell, it can be determined whether the second number of RedCap dedicated BWPs currently configured in the serving cell is greater than the first number; if the second number of RedCap dedicated BWPs currently configured in the serving cell is less than or equal to the first number, there is no need to sort out and recycle the RedCap dedicated BWPs; on the contrary, if the second number of RedCap dedicated BWPs currently configured in the serving cell is greater than the first number, some RedCap dedicated BWPs can be selected from the currently configured RedCap dedicated BWPs, and the RedCap terminals on these RedCap dedicated BWPs can be reconfigured and grouped to other RedCap dedicated BWPs through RRC connection, that is, the following S602 and S603 are executed:

[0169] S602: Determine the fifth RedCap dedicated BWP to be released from the configured RedCap dedicated BWPs.

[0170] For example, in an embodiment of the present application, when determining the fifth RedCap dedicated BWP to be released from the configured RedCap dedicated BWP, the first third number of RedCap dedicated BWPs in the configured RedCap dedicated BWP can be determined as the fifth RedCap dedicated BWP in the order of frequency band from high to low, or in the order of frequency band from low to high. In this way, not only the fifth RedCap dedicated BWP to be released can be determined, but also continuous channel resources can be allocated to conventional type terminals, thereby effectively ensuring the continuity of service channel resources and improving the utilization of channel resources. Wherein, the third number is greater than or equal to the difference between the second number and the first number, and is less than the second number.

[0171] For example, it is assumed that the first number of RedCap dedicated BWPs to be configured is 4, the second number of RedCap dedicated BWPs configured in the current serving cell is 5, and the order from high to low in frequency band is: RedCap dedicated BWP1, RedCap dedicated BWP2, RedCap dedicated BWP3, RedCap dedicated BWP4 and RedCap dedicated BWP5. When determining the fifth RedCap dedicated BWP to be released,

[0172] Then, RedCap dedicated BWP1 can be selected as the fifth RedCap dedicated BWP to be released in the order of frequency bands from high to low; or RedCap dedicated BWP1 and RedCap dedicated BWP2 can be selected as the fifth RedCap dedicated BWP to be released. The specific settings can be made according to actual needs.

[0173] or,

[0174] When determining the fifth RedCap dedicated BWP to be released, you can also select RedCap dedicated BWP5 as the fifth RedCap dedicated BWP to be released in the order of frequency band from low to high; you can also select RedCap dedicated BWP5 and RedCap dedicated BWP4 as the fifth RedCap dedicated BWP to be released. The specific settings can be made according to actual needs.

[0175] It can be understood that in the embodiment of the present application, in addition to determining the fifth RedCap dedicated BWP in order of frequency band from high to low, or in order of frequency band from low to high, the first third RedCap dedicated BWP with a smaller number of RedCap terminals accommodated can also be determined as the fifth RedCap dedicated BWP in order of the number of RedCap terminals accommodated from small to large, thereby improving the release efficiency of the RedCap dedicated BWP.

[0176] It should be noted that in the embodiment of the present application, when arranging relatively idle RedCap dedicated BWPs, the fifth RedCap dedicated BWP to be released can also be determined in combination with the above two factors. Among them, on the one hand, the RedCap dedicated BWP with only a small number of RedCap terminals is preferentially determined as the fifth RedCap dedicated BWP to be released; on the other hand, in the order of frequency band from high to low, or in the order of frequency band from low to high, the continuity of service channel resources of conventional terminals needs to be guaranteed as much as possible.

[0177] After the fifth RedCap dedicated BWP to be released is determined, the following S603 may be executed:

[0178] S603. Reconfigure the RedCap terminal accommodated in the fifth RedCap dedicated BWP to other RedCap dedicated BWPs, and release the fifth RedCap dedicated BWP; wherein, the other RedCap dedicated BWPs are the RedCap dedicated BWPs among the configured RedCap dedicated BWPs except the fifth RedCap dedicated BWP.

[0179] After releasing the fifth RedCap dedicated BWP, the common channel resources can be recovered, the continuity of frequency domain resources can be maintained, and the total system throughput can be improved.

[0180] It can be seen that in an embodiment of the present application, when the second number of RedCap dedicated BWPs currently configured in the service cell is greater than the first number of RedCap dedicated BWPs to be configured, the fifth RedCap dedicated BWP can be selected from the configured RedCap dedicated BWPs in order of frequency band from high to low, or in order of frequency band from low to high, and the RedCap terminal accommodated in the fifth RedCap dedicated BWP can be reconfigured to other RedCap dedicated BWPs, and the fifth RedCap dedicated BWP can be released. This not only organizes relatively idle RedCap dedicated BWPs, but also allocates continuous channel resources to conventional type terminals, thereby effectively ensuring the continuity of service channel resources and improving the utilization rate of channel resources.

[0181] Based on any of the above embodiments, considering that for a certain RedCap dedicated BWP, as the number of RedCap terminals on the RedCap dedicated BWP decreases, after all the RedCap terminals release the RRC connections, the RedCap dedicated BWP is in an idle state, which not only occupies channel resources, but also causes discontinuity of service channel resources. For example, in an embodiment of the present application, when all the RedCap terminals accommodated by the target RedCap dedicated BWP release their connections, the target RedCap dedicated BWP can be released, so that the uplink and downlink common channel resources on the target RedCap dedicated BWP can be recovered, so that the channel resources can allow the allocated conventional types of terminals to continue to use, which not only ensures the continuity of service channel resources, but also improves the utilization rate of channel resources.

[0182] It should be noted that, in the embodiment of the present application, if part of the RedCap dedicated BWP has been released, and the remaining configured RedCap dedicated BWP is not continuous in the frequency domain, in this case, the terminal on the RedCap dedicated BWP with a large number can be reconfigured to the RedCap dedicated BWP with a small number. After all the terminals on the RedCap dedicated BWP with a large number are released, the RedCap dedicated BWP with a large number can be released. In this way, the continuity of the BWP with a small cell number in the frequency domain can be maintained as much as possible.

[0183] Figure 7 A schematic diagram of the structure of a network device provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, the network device includes a memory 720, a transceiver 700, and a processor 710, wherein:

[0184] The memory 720 is used to store computer programs; the transceiver 700 is used to send and receive data under the control of the processor 710; the processor 710 is used to read the computer program in the memory 720 and perform the following operations:

[0185] In the case where a first RedCap terminal desires to access a serving cell, a target RedCap dedicated BWP for accommodating the first RedCap terminal is determined according to whether a configured first RedCap dedicated BWP currently exists in the serving cell.

[0186] The target RedCap dedicated BWP is configured for the first RedCap terminal, and the target RedCap dedicated BWP is used for the first RedCap terminal to perform data transmission.

[0187] Specifically, the transceiver 700 is used to receive and send data under the control of the processor 710.

[0188] Among them, Figure 7 In the embodiment, the bus architecture may include any number of interconnected buses and bridges, specifically linking together various circuits of one or more processors represented by processor 710 and memory represented by memory 720. The bus architecture may also link together various other circuits such as peripherals, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. The bus interface provides an interface. The transceiver 700 may be a plurality of components, namely, a transmitter and a receiver, providing a unit for communicating with various other devices on a transmission medium, which may include a wireless channel, a wired channel, an optical cable, and other transmission media. The processor 710 is responsible for managing the bus architecture and general processing, and the memory 720 may store data used by the processor 710 when performing operations.

[0189] The processor 710 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or a complex programmable logic device (CPLD). The processor may also adopt a multi-core architecture.

[0190] For example, in the embodiment of the present application, determining the target RedCap dedicated BWP that accommodates the first RedCap terminal according to whether the serving cell currently has a configured first RedCap dedicated BWP includes:

[0191] If it is determined that the first RedCap dedicated BWP does not exist, the BWP of the highest frequency band or the BWP of the lowest frequency band in the serving cell is newly created as the target RedCap dedicated BWP;

[0192] In the case where it is determined that the first RedCap dedicated BWP exists, the target RedCap dedicated BWP is determined according to a related value of the first RedCap dedicated BWP; wherein the related value includes the number of accommodated second RedCap terminals and / or channel utilization.

[0193] For example, in the embodiment of the present application, determining the target RedCap dedicated BWP according to the correlation value of the first RedCap dedicated BWP includes:

[0194] In a case where the correlation value of the first RedCap dedicated BWP is less than a first correlation value, determining the first RedCap dedicated BWP as the target RedCap dedicated BWP;

[0195] In the case where the correlation value of the first RedCap dedicated BWP is greater than or equal to the first correlation value, it is determined whether the serving cell can newly build a second RedCap dedicated BWP; and the target RedCap dedicated BWP is determined according to the determination result.

[0196] For example, in the embodiment of the present application, determining the target RedCap dedicated BWP according to the judgment result includes:

[0197] If the judgment result indicates that the second RedCap dedicated BWP can be newly created, determining the second RedCap dedicated BWP as the target RedCap dedicated BWP;

[0198] When the judgment result indicates that the second RedCap dedicated BWP cannot be newly created, if the correlation value of the first RedCap dedicated BWP is less than the second correlation value, the first RedCap dedicated BWP is set as the target RedCap dedicated BWP; wherein the second correlation value is greater than the first correlation value.

[0199] For example, in the embodiment of the present application, the processor 710 is further configured to perform the following operations:

[0200] Determine whether there is a third RedCap dedicated BWP with a correlation value greater than the first correlation value among the RedCap dedicated BWPs configured in the serving cell, and whether there is a fourth RedCap dedicated BWP with a correlation value less than the first correlation value;

[0201] In the case where it is determined that the third RedCap dedicated BWP and the fourth RedCap dedicated BWP exist, part of the RedCap terminals accommodated by the third RedCap dedicated BWP are reconfigured to the fourth RedCap dedicated BWP.

[0211] It should be noted here that the above-mentioned network device provided in the embodiment of the present application can implement all the method steps implemented in the above-mentioned embodiment, and can achieve the same technical effect. The parts and beneficial effects of this embodiment that are the same as the method embodiment will not be described in detail here.

[0212] In addition, the embodiment of the present application also provides a configuration device for the bandwidth BWP of the dedicated part of RedCap with reduced capacity. It can be understood that the configuration device for the bandwidth BWP of the dedicated part of RedCap with reduced capacity and the configuration method for the bandwidth BWP of the dedicated part of RedCap with reduced capacity are based on the same application concept, and the principles of solving the problem are similar. Therefore, the implementation of the configuration device for the bandwidth BWP of the dedicated part of RedCap with reduced capacity and the configuration method for the bandwidth BWP of the dedicated part of RedCap with reduced capacity can refer to each other, and the repeated parts will not be repeated.

[0217] When it is determined that the first RedCap dedicated BWP does not exist, the BWP of the highest frequency band or the BWP of the lowest frequency band in the serving cell is newly created as the target RedCap dedicated BWP.

[0223] When the judgment result indicates that the second RedCap dedicated BWP can be newly created, the second RedCap dedicated BWP is determined as the target RedCap dedicated BWP.

[0224] When the judgment result indicates that the second RedCap dedicated BWP cannot be newly created, if the correlation value of the first RedCap dedicated BWP is less than the second correlation value, the first RedCap dedicated BWP is set as the target RedCap dedicated BWP; wherein the second correlation value is greater than the first correlation value.

[0230] The second determining unit is used to determine a fifth RedCap dedicated BWP to be released from the configured RedCap dedicated BWPs when a second number of the RedCap dedicated BWPs configured in the serving cell is greater than the first number.

[0231] The second reconfiguration unit is used to reconfigure the RedCap terminal accommodated in the fifth RedCap dedicated BWP to other RedCap dedicated BWPs.

[0232] The first releasing unit is used to release the fifth RedCap dedicated BWP; wherein the other RedCap dedicated BWPs are the RedCap dedicated BWPs among the configured RedCap dedicated BWPs except the fifth RedCap dedicated BWP.
