[0002] To build 5G base stations efficiently and at low cost, co-construction and sharing with other operators is an inevitable choice for operators. Among these, carrier sharing is one solution for operators to co-construct and share access networks.

[0003] In 5G standalone networking with shared carriers, the URLLC (Ultra Reliable Low Latency Communication) and eMBB (Enhanced Mobile Broadband) services of the two operators are mixed together. The two services will inevitably conflict in terms of resources, which will make it difficult to guarantee user throughput and reliability.

[0004] Therefore, there is an urgent need in this field for a method that can flexibly manage end users.

[0029] If the target terminal user is the target terminal user of the sharing party, then based on the target terminal user control field and the target terminal user control field of the sharing party in the user control field, it is determined whether the target terminal user is allowed to access the operator network corresponding to the base station;

[0042] The exemplary embodiments disclosed herein can have the following beneficial effects:

[0043] In the terminal user control method of this exemplary embodiment, a user control field for controlling the target terminal user is added to the system message broadcast by the base station to each terminal. This field includes a target terminal user control field, a shared target terminal user control field, and a resource preemption control field, thereby controlling the access status and resource preemption mode of the target terminal user. On the one hand, the terminal user control method in this exemplary embodiment allows for flexible management of the target terminal user through the user control field carried in the system message. This enables the target terminal user to access the entire shared carrier or the local network frequency band, and also allows control over whether resource preemption is supported, ensuring user throughput and reliability. On the other hand, by broadcasting system messages, cell blocking is implemented for specific terminal users and specific terminal capabilities. When resources are congested, operators can dynamically control the access of the target terminal user, ensuring that the current cell does not experience a decline in overall experience due to service congestion of the target terminal user. This reduces the impact of limited cell resources on user service experience, quickly and effectively balances network load, and guarantees the reliability and performance of the remaining users.

[0057] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete, and to fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a full understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, components, apparatus, steps, etc., can be employed. In other instances, well-known technical solutions are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0058] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0059] Because 5G operates at higher frequencies, more base stations need to be deployed under the same coverage, resulting in higher power consumption (about three times that of 4G). Therefore, co-construction and sharing with other operators has become inevitable in order to build 5G base stations at low cost and high efficiency.

[0060] In the SA (Standalone) phase, operators co-build and share base stations and carriers, ensuring no interference between different operators. Users camp on the network based on the operator's dedicated frequency priority policy. The operator's 5G standalone access network sharing technology solution is as follows: Figure 1 As shown, both Operator A and Operator B adopt the 5G SA network architecture. The two share only the 5G NR (New Radio) radio access network, while their core networks 5GC are independent.

[0061] Shared carrier is a scheme for operators to jointly build and share access networks. When sharing a carrier, the BBU (Building Baseband Unit), RRU / AAU (Remote Radio Unit / Active Antenna Unit) are all shared, and the site-side RAN (Radio Access Network) equipment is also fully shared. By sharing one or more segments of carriers from different operators, a continuous large-bandwidth shared carrier is formed, further reducing infrastructure and equipment costs.

[0062] Under 5G SA carrier sharing, URLLC (Ultra-Reliable Low-Latency Communication) and eMBB (Enhanced Mobile Broadband) services from two operators are mixed together. Resource conflicts between URLLC and eMBB services are inevitable. URLLC services, with their higher requirements for latency and reliability, need to be prioritized. Currently, existing technologies prioritize URLLC services, sacrificing eMBB services, resulting in a compromised eMBB service experience.

[0063] Furthermore, since URLLC typically involves bursty data transmission, reserving resources for it indefinitely would result in resource waste when there is no URLLC data to transmit. Therefore, in concurrent URLLC and eMBB scenarios, URLLC typically preempts eMBB resources for transmission.

[0064] R15 and R16 (5G mobile communication standards) respectively proposed downlink / uplink channel multiplexing and preemption for URLLC.

[0065] In scenarios where eMBB and URLLC services coexist, to meet the low-latency requirements of URLLC services, NR in Release 15 supports URLLC users preempting downlink time-frequency resources already allocated to eMBB users, ensuring that URLLC services are available immediately upon arrival. When time-frequency resource preemption occurs, URLLC users will utilize the time-frequency resource to transmit data, while eMBB users will cease service transmission on that time-frequency resource. Since PDSCH (Physical Downlink Shared Channel) data is overwritten and decoding errors occur in eMBB scenarios, a downlink preemption indication mechanism is introduced to avoid the impact of this preemption mechanism on eMBB services. This is compensated for by using DCI (Downlink Control Information) format 2-1, i.e., sending a PI (Pre-emption Indication) to the terminal to indicate that URLLC has occupied resources. By indicating which parts have been preempted, subsequent retransmission and decoding will prevent the previously preempted portions from being used for retransmission and decoding. Specifically... Figure 2 As shown. DCI format 2_1 uses INT-RNTI (Interruption Radio Network Temporary Identity, used to indicate preemption during downlink data transmission) scrambling. The size of DCI format 2_1 can be up to 126 bits, of which each preemption indication is 14 bits, used to correspond to 14 OFDM (Orthogonal Frequency Division Multiplexing) symbols in the slot.

[0066] Similarly, when UEs (User Equipment) of different service types coexist in the same network, radio resource allocation conflicts can arise due to the uncertainty of the timing of services with different priorities. To address uplink resource allocation conflicts between UEs, 3GPP (3rd Generation Partnership Project) Release 16 supports an uplink transmission cancellation scheme. For example... Figure 3As shown, uplink transmission cancellation supports the URLLC UE's preemption of uplink resources allocated to the eMBB UE. The base station notifies the eMBB user of the uplink cancellation indication (CI) via DCI format 2_4, indicating the location of the uplink data resources to be occupied by the URLLC UE, including the PRB (Physical Resource Block) and continuous OFDM symbol information. This DCI (Downlink Control Information) can be configured by higher-layer signaling, and the load size, indicated time-frequency resources, and time-domain granularity are also configured by higher-layer signaling, using CI-RNTI (Cancellation Indicator for Uplink Cancellation) for scrambling. The uplink cancellation indication can be applied to PUSCH (Physical Uplink Shared Channel) and SRS (Sounding Reference Signal, a type of uplink physical signal). When the uplink cancellation signaling indicates PUSCH, PUSCH transmission is cancelled starting from the first indicated time-domain symbol. When an uplink cancellation signaling instruction (SRS) is received, only the data transmission at the indicated symbol location is cancelled. For subsequent symbol resources that are not indicated, SRS transmission can continue. On the other hand, after receiving the uplink cancellation instruction, the eMBB user stops the uplink transmission of the indicated resource to reduce interference with URLLC data and improve the reliability of URLLC transmission.

[0067] However, in the aforementioned embodiments, using downlink resource preemption and uplink cancellation indication to stop eMBB user uplink and downlink transmissions both come at the cost of eMBB terminal user throughput, and URLLC data demodulation performance is also affected by interference. If URLLC resource preemption occurs frequently by a certain sharing party, it will result in low eMBB throughput and reduced URLLC reliability for the entire shared carrier, and operators will not be able to flexibly configure sharing strategies.

[0068] To address the aforementioned issues, this exemplary implementation first provides a control method for end users, applied to a base station. (Reference) Figure 4 As shown, the control method for the end user described above may include the following steps:

[0069] Step S410. Send system information containing user control fields to all terminal users within the coverage area of ​​the base station.

[0070] Step S420. Control the access status and resource preemption mode of target terminal users using ultra-reliable and low-latency communication services through the user control field in the system information.

[0071] The user control field includes the target terminal user control field, the sharing party target terminal user control field, and the resource preemption control field.

[0072] In the terminal user control method of this exemplary embodiment, a user control field for controlling the target terminal user is added to the system message broadcast by the base station to each terminal. This field includes a target terminal user control field, a shared target terminal user control field, and a resource preemption control field, thereby controlling the access status and resource preemption mode of the target terminal user. On the one hand, the terminal user control method in this exemplary embodiment allows for flexible management of the target terminal user through the user control field carried in the system message. This enables the target terminal user to access the entire shared carrier or the local network frequency band, and also allows control over whether resource preemption is supported, ensuring user throughput and reliability. On the other hand, by broadcasting system messages, cell blocking is implemented for specific terminal users and specific terminal capabilities. When resources are congested, operators can dynamically control the access of the target terminal user, ensuring that the current cell does not experience a decline in overall experience due to service congestion of the target terminal user. This reduces the impact of limited cell resources on user service experience, quickly and effectively balances network load, and guarantees the reliability and performance of the remaining users.

[0073] The following is combined with Figure 5 The steps described above in this example implementation will be explained in more detail.

[0074] In step S410, system information containing user control fields is sent to all terminal users within the coverage area of ​​the base station.

[0075] In this example implementation, since the operator base station broadcasts SIB1 (System Information Block Type 1) messages to all terminal users within its coverage area at a certain transmission period, user control fields can be carried in the system messages broadcast over the network. These user control fields include target terminal user control fields, sharing party target terminal user control fields, and resource preemption control fields.

[0076] Specifically, in network broadcast SIB1, for each PLMN (Public Land Mobile Network), newly defined fields can be added: the target end-user control field URLLCBarred, the sharing party target end-user control field SharedBarred, and the resource preemption control field PreemptionBarred.

[0077] In step S420, the access status and resource preemption mode of the target terminal user using the ultra-reliable and low-latency communication service are controlled through the user control field in the system information.

[0078] In this example implementation, the target end user refers to a URLLC end user who supports and uses URLLC service functions. The target end user control field `URLLCBarred` determines whether all URLLC end users are allowed to access the service; the shared party target end user control field `SharedBarred` determines whether all shared party URLLC end users are allowed to access the service; and the resource preemption control field `PreemptionBarred` determines how accessible URLLC end users preempt resources.

[0079] In this example implementation, such as Figure 5 As shown, the access status and resource preemption mode of target terminal users using ultra-reliable and low-latency communication services are controlled through the user control field in the system information. Specifically, this can include the following steps:

[0080] Step S510. Based on the target terminal user control field in the user control field, determine whether the operator network corresponding to the base station allows the target terminal user to access.

[0081] First, based on the target terminal user control field URLLCBarred in the user control field, it is determined whether the operator network corresponding to the base station allows all target terminal users to access. Specifically, this can be determined by the value of URLLCBarred. For example, when the value of URLLCBarred is "1", it means "deny URLLC terminal user access", and when the value of URLLCBarred is "0", it means "allow URLLC terminal user access".

[0082] Step S520. If access is allowed for the target terminal user, determine whether the operator network corresponding to the base station allows access for the target terminal user among the target terminal users based on the shared target terminal user control field in the user control field.

[0083] If access is allowed for the target terminal user (i.e., the value of URLLCBarred is "0"), then the SharedBarred field in the user control field is used again to determine whether the operator network corresponding to the base station allows access for the shared target terminal user. Specifically, this can be determined by the value of SharedBarred. For example, a value of "1" indicates "deny access for the shared URLLC terminal user," while a value of "0" indicates "allow access for the shared URLLC terminal user." The operator type of the shared target terminal user differs from the operator type of the base station.

[0084] In other words, when the value of URLLCBarred is "1", it means that URLLC terminal users of all operators are not allowed to access; when the value of URLLCBarred is "0" and the value of SharedBarred is "0", it means that URLLC terminal users of all operators are allowed to access; when the value of URLLCBarred is "0" and the value of SharedBarred is "1", it means that only the URLLC terminal users corresponding to the base station main construction party are allowed to access, while the URLLC terminal users of the sharing party are not allowed to access.

[0085] Step S530. Determine the resource preemption control field for all allowed target terminal users based on the resource preemption control field in the user control field.

[0086] In this example implementation, the resource preemption method for all allowed target terminal users can be determined by the value of the resource preemption control field PreemptionBarred. The specific method is as follows:

[0087] If the resource preemption control field is the first resource preemption control field, the target terminal user is allowed to preempt uplink and downlink enhanced mobile broadband resources; if the resource preemption control field is the second resource preemption control field, the target terminal user is allowed to preempt downlink enhanced mobile broadband resources, but is prohibited from preempting uplink enhanced mobile broadband resources; if the resource preemption control field is the third resource preemption control field, the target terminal user is allowed to preempt uplink enhanced mobile broadband resources, but is prohibited from preempting downlink enhanced mobile broadband resources; if the resource preemption control field is the fourth resource preemption control field, the target terminal user is prohibited from preempting uplink and downlink enhanced mobile broadband resources.

[0088] For example, if PreemptionBarred is the first resource preemption control field "00", it means "URLLC end users are allowed to preempt uplink and downlink eMBB resources"; if PreemptionBarred is the second resource preemption control field "01", it means "URLLC end users are allowed to preempt downlink eMBB resources, but are prohibited from preempting uplink eMBB resources"; if PreemptionBarred is the third resource preemption control field "10", it means "URLLC end users are allowed to preempt uplink eMBB resources, but are prohibited from preempting downlink eMBB resources"; if PreemptionBarred is the fourth resource preemption control field "11", it means "URLLC end users are prohibited from preempting uplink and downlink eMBB resources".

[0089] In this example implementation, under a shared carrier scenario, by sending different standard control identifiers for each PLMN during SIB1 message broadcasting, a flexible means is provided for operator network sharing. This ensures the throughput of eMBB and the reliability of URLLC when eMBB and URLLC are reused under shared carrier networking, improves reuse efficiency, and enhances the user experience of eMBB and URLLC under 5G SA co-construction and shared carriers. This is beneficial for the implementation and promotion of 5G SA shared carrier technology solutions. The addition of new fields enables customized and personalized user management for each cell, resulting in more accurate control.

[0090] Additionally, this example implementation also provides a control method for an end user, applied to a target end user. (See reference) Figure 6 As shown, the control method for the end user described above may include the following steps:

[0091] Step S610. Receive system information containing user control fields sent by the base station, and obtain the user control fields through the system information.

[0092] Step S620. Obtain the operator type of the target terminal user and the operator type of the base station.

[0093] Step S630. Based on the user control field, the operator type of the target terminal user, and the operator type of the base station, determine the access status and resource preemption method of the target terminal user.

[0094] The user control field includes the target terminal user control field, the sharing party target terminal user control field, and the resource preemption control field.

[0095] Below, in conjunction with Figure 7 The steps described above in this example implementation will be explained in more detail.

[0096] In step S610, system information containing user control fields sent by the base station is received, and the user control fields are obtained through the system information.

[0097] In this example implementation, the target terminal user, i.e., the URLLC terminal user, can obtain its corresponding user control field by receiving and parsing the system information SIB1 containing user control fields sent by the base station. The user control field includes the target terminal user control field, the sharing party target terminal user control field, and the resource preemption control field.

[0098] In step S620, the operator type of the target terminal user and the operator type of the base station are obtained.

[0099] By obtaining the carrier type of the target terminal user and the carrier type of the base station, it can be determined whether the target terminal user is the target terminal user of the sharing party.

[0100] In step S630, the access status and resource preemption method of the target terminal user are determined based on the user control field, the operator type of the target terminal user, and the operator type of the base station.

[0101] In this example implementation, such as Figure 7 As shown, based on the user control fields, the target terminal user's carrier type, and the base station's carrier type, the access status and resource preemption method of the target terminal user are determined. This can specifically include the following steps:

[0102] Step S710. Determine whether the target terminal user is a shared target terminal user based on the operator type of the target terminal user and the operator type of the base station.

[0103] If the target terminal user's own operator type is different from the base station's operator type, then the target terminal user is determined to be the sharing party's target terminal user.

[0104] Step S720. If the target terminal user is not the target terminal user of the sharing party, then determine whether the target terminal user is allowed to access the operator network corresponding to the base station based on the target terminal user control field in the user control field.

[0105] If the target terminal user is the target terminal user corresponding to the base station's main construction party, and not the target terminal user of the sharing party, then it is only necessary to determine whether the current target terminal user can access the network based on the target terminal user control field URLLCBarred in the user control field. If the value of URLLCBarred is "0", then the current target terminal user can access the operator network corresponding to the base station.

[0106] Step S730. If the target terminal user is the target terminal user of the sharing party, then determine whether the target terminal user is allowed to access the operator network corresponding to the base station based on the target terminal user control field and the target terminal user control field of the sharing party in the user control field.

[0107] If the target terminal user is the same as the target terminal user of the sharing party, then access permission needs to be determined based on both the target terminal user control field and the target terminal user control field of the sharing party. Specifically, the current target terminal user can only access the operator network corresponding to the base station if both URLLCBarred and SharedBarred are "0".

[0108] Step S740. If the target terminal user is allowed to access the operator network corresponding to the base station, then determine the resource preemption method of the target terminal user according to the resource preemption control field in the user control field.

[0109] If the target terminal user is allowed to access the operator's network corresponding to the base station, the resource preemption method of the current target terminal user is determined according to the resource preemption control field PreemptionBarred.

[0110] If PreemptionBarred is the first resource preemption control field "00", then the current target terminal user is allowed to preempt uplink and downlink eMBB resources; if PreemptionBarred is the second resource preemption control field "01", then the current target terminal user is allowed to preempt downlink eMBB resources, but is prohibited from preempting uplink eMBB resources; if PreemptionBarred is the third resource preemption control field "10", then the current target terminal user is allowed to preempt uplink eMBB resources, but is prohibited from preempting downlink eMBB resources; if PreemptionBarred is the fourth resource preemption control field "11", then the current target terminal user is prohibited from preempting uplink and downlink eMBB resources.

[0111] like Figure 8 The diagram shown is a complete flowchart of a specific embodiment of this disclosure, illustrating the steps described above in this example embodiment. The specific steps of the flowchart are as follows:

[0112] Step S810. Broadcast a system message and carry user control fields.

[0113] For network broadcast SIB1, for each PLMN, add the following newly defined fields: 1 bit URLLCBarred, 1 bit SharedBarred, and 2 bits PreemptionBarred.

[0114] Step S820. The terminal receives system messages.

[0115] The terminal receives and parses the SIB1 message to obtain the user control field.

[0116] Step S830. Determine the URLLCBarred field.

[0117] If the value of URLLCBarred is "1", it means "URLLC end-user access denied", and the process ends; if the value of URLLCBarred is "0", it means "URLLC end-user access allowed", and proceeds to step S850.

[0118] Step S840. Determine the SharedBarred field.

[0119] If the value of SharedBarred is "1", it means "rejecting access for the sharing party's URLLC end user", and the process ends; if the value of SharedBarred is "0", it means "allowing access for the sharing party's URLLC end user", and proceeds to step S860.

[0120] Step S850. Determine the first bit of the PreemptionBarred field.

[0121] If the first bit of PreemptionBarred is "1", proceed to step S860; if the first bit of PreemptionBarred is "0", proceed to step S870.

[0122] Step S860. Determine the tail bit of the PreemptionBarred field.

[0123] If the last bit of PreemptionBarred is "1", then the value of PreemptionBarred is "11", which means "URLLC terminal users are prohibited from preempting uplink and downlink eMBB resources"; if the last bit of PreemptionBarred is "0", then the value of PreemptionBarred is "10", which means "URLLC terminal users are allowed to preempt uplink eMBB resources, but are prohibited from preempting downlink eMBB resources".

[0124] Step S870. Determine the tail bit of the PreemptionBarred field.

[0125] If the last bit of PreemptionBarred is "1", then the PreemptionBarred field will be "01", which means "URLLC terminal users are allowed to preempt downlink eMBB resources, but are prohibited from preempting uplink eMBB resources"; if the last bit of PreemptionBarred is "0", then the PreemptionBarred field will be "00", which means "URLLC terminal users are allowed to preempt uplink and downlink eMBB resources".

[0126] The control method for end users in the exemplary embodiments of this disclosure can be directly applied to 200M SA networks shared by various operators, especially in scenarios where latency-sensitive and non-latency-sensitive services coexist, ensuring the user experience of each operator's eMBB and URLLC.

[0127] In certain SA (Autonomous Vehicle) shared carrier scenarios, such as congested roads for autonomous vehicles, URLLC (URLLC) preempts a large amount of eMBB resources. In such scenarios, controlling the access and preemption scheme of URLLC users can effectively manage users, share resources, balance users, and avoid accidents while ensuring user experience.
