Description

Technical Field

[0001] The present disclosure relates to the field of mobile communication technology, and in particular to a service preemption adjustment method and device. Background Art

[0002] In standalone (SA) networking, different operators build and share base stations and carriers, preventing interference between operators. Users reside based on the operators' proprietary frequency priority policies. As shown in Figure 1, the networking diagram of the 5G SA access network sharing technology solution shows that both operators A and B use the 5G SA networking architecture. They only share the radio access network, while their core networks (5GC, 5G Core) are independent.

[0003] In 200M SA shared networking, the carriers are independently configured, and operators A and B each have 100M carriers and independent cells, which are managed separately. Neighboring cells, switching, residency, and inter-network interoperability are the same as independent construction. 5G base stations share physical equipment and resources. Both operator cells broadcast the PLMN (Public Land Mobile Network) numbers of the two operators, but the operator A terminal ultimately resides in the operator A frequency band cell, and the operator B user ultimately resides in the operator B frequency band cell. Each cell SIB (system information block) message carries the PLMNs of multiple operators. If an operator A user initially accesses the operator B cell, the base station first sends a measurement and control event, and the terminal reports the measurement report and then switches back to operator A.

[0004] In scenarios where eMBB (Enhanced Mobile Broadband) services coexist with URLLC (Ultra-reliable and Low Latency Communications) services, URLLC users are supported to preempt resources allocated to eMBB users to meet the low latency requirements of URLLC services, ensuring that URLLC services are delivered as soon as they arrive. However, in 200M SA shared networking, there are scenarios where one sharer experiences a high frequency of URLLC resource preemption, resulting in low eMBB throughput and reduced URLLC reliability, while the other sharer experiences a low number of URLLC terminal accesses and a low frequency of preemption. Summary of the Invention

[0005] The disclosed embodiment adjusts the URLLC preemption scheme to balance the frequency of URLLC preemption on both sides of the sharing, thereby ensuring the eMBB throughput and URLLC reliability in the case of shared networking eMBB and URLLC multiplexing, improving the multiplexing efficiency, and improving the eMBB and URLLC user experience under the 5G SA co-construction and sharing of the 200M shared carrier, which is conducive to the implementation and promotion of the 5G SA 200M shared carrier technology solution.

[0057] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure.

[0058] Unless otherwise specified, descriptions such as “first” and “second” in the present disclosure are used to distinguish different objects and are not used to indicate meanings such as size or time sequence.

[0059] In the scenario where eMBB services and URLLC services coexist, in order to meet the low latency requirements of URLLC services, 3GPP R15NR (New Radio) supports URLLC users to preempt downlink time-frequency resources that have been allocated to eMBB users to ensure that URLLC services are transmitted as soon as they arrive. When time-frequency resource preemption occurs, URLLC users will use the time-frequency resources to transmit data, and eMBB users will stop service transmission on the time-frequency resources. Since the PDSCH data in the eMBB scenario is overwritten and decoded incorrectly, in order to avoid the impact of the preemption mechanism on the eMBB service, a downlink resource preemption indication mechanism is introduced. Figure 2AAs shown, the performance loss is compensated by using DCI (Downlink Control Information) format 2-1, that is, a PI (Pre-emption Indication) is sent to the terminal to indicate that URLLC has occupied resources. By indicating which positions have been dropped, the previously dropped parts cannot be used for merging and decoding during subsequent retransmission, merging and decoding. DCI format 2_1 is scrambled using INT-RNTI (Interrupted transmission indication Radio Network Temporary Identity), and INT-RNTI is used to indicate downlink pre-occupancy resource occupancy information. The size of DCI format 2_1 can be up to 126 bits, of which each preemption indication is 14 bits, which are used for 14 OFDM (Orthogonal Frequency Division Multiplexing) symbols in the corresponding time slot.

[0060] When user equipment (UE) of different service types coexist in the same network, wireless resource allocation conflicts will arise due to the uncertainty of the timing of services of different priorities. In response to uplink resource allocation conflicts between UEs, 3GPP R16 supports uplink transmission cancellation schemes. Uplink transmission cancellation means that for URLLC UEs that forcibly occupy uplink resources allocated to eMBB UEs, the base station notifies the eMBB user through DCI format 2_4 carrying uplink transmission cancellation indication (CI), indicating the uplink data resource location to be occupied by the URLLC UE, including PRB (physical resource block) and continuous OFDM symbol information. The DCI can be configured by high-level signaling, and the load size, the indicated time-frequency resources and the time domain granularity are configured by high-level signaling, and CI-RNTI is used for scrambling. The uplink transmission cancellation indication can be applied to PUSCH (Physical Uplink Share CHannel) and SRS (Sounding Reference Signal). When the uplink transmission cancellation indication is applied to PUSCH, PUSCH transmission is cancelled starting from the first time domain symbol indicated. When the uplink transmission cancellation indication is applied to SRS, only the data transmission at the indicated symbol position is cancelled. For subsequent symbol resources that are not indicated, SRS can continue to be transmitted, such as Figure 2BAs shown in the figure, for the eMBB UE, the two symbols indicated by the dashed box have transmission canceled due to preemption. The remaining unoccupied symbols can continue to transmit SRS. On the other hand, upon receiving the uplink transmission cancellation indication, the eMBB UE stops uplink transmission on the indicated resources to reduce interference with URLLC data and improve URLLC transmission reliability.

[0061] However, using downlink resource preemption indication and uplink transmission cancellation indication to stop the uplink / downlink transmission of eMBB users comes at the expense of eMBB UE throughput, and URLLC data demodulation performance is also affected by interference factors.

[0062] Figure 3 A flow chart illustrating a method for adjusting the URLLC service preempting downlink time-frequency resources according to some embodiments of the present disclosure is shown.

[0063] like Figure 3 As shown, the method of this embodiment includes steps 310-330.

[0064] In step 310, in a scenario where the URLLC terminal can preempt downlink time-frequency resources allocated to the eMBB terminal, a first frequency number of downlink resource preemption indications occurring within a certain period of time at the frequency point of the first sharing party is counted.

[0065] Since the downlink resource preemption indication can be carried by DCI format 2-1, this step may, for example, count the first frequency of occurrence of DCI format 2-1 within a certain period of time at the frequency point of the first sharing party.

[0066] The first sharing party and the subsequent second sharing party are, for example, different operators. The networking mode of the first sharing party and the second sharing party is: the access network is jointly built and shared, and the core network is independent.

[0067] At step 320, the first frequency is compared with a first correlation threshold;

[0068] In some embodiments, the first correlation threshold includes a first upper threshold and a first lower threshold, but is not limited to the examples given. For example, the first correlation threshold may also include a threshold.

[0069] In step 330, based on the comparison result of the first frequency and the first related threshold, the URLLC terminal that meets the preset conditions is reselected to the frequency point of the second sharing party with the same coverage.

[0070] In some embodiments, when the first relevant threshold includes a first upper threshold and a first lower threshold, if the first frequency number is greater than or equal to the first upper threshold, at least part of the URLLC terminals with no business residing on the first sharing party are reselected to the frequency point of the second sharing party with the same coverage (step 331); or, if the first frequency number is less than the first upper threshold and greater than the first lower threshold, the new URLLC terminal is controlled to access the frequency point of the second sharing party with the same coverage (step 332); or, if the first frequency number is less than or equal to the first lower threshold, the URLLC terminal residing on or accessing the first sharing party is allowed to preempt the downlink time-frequency resources allocated to the eMBB terminal, that is, the URLLC business preemption strategy is not adjusted for the time being, and monitoring continues (step 333).

[0071] In other embodiments, when the first related threshold includes a threshold, if the first frequency number is greater than or equal to the threshold, at least part of the URLLC terminals with no business residing in the first sharing party will be reselected to the frequency point of the second sharing party with the same coverage, or the new URLLC terminals will be controlled to access the frequency point of the second sharing party with the same coverage; if the first frequency number is less than the threshold, the URLLC terminals residing in or accessing the first sharing party are allowed to preempt the downlink time and frequency resources allocated to the eMBB terminal, that is, the URLLC business preemption strategy will not be adjusted for the time being, and monitoring will continue.

[0072] By adjusting the URLLC preemption scheme for downlink time-frequency resources, the frequency of URLLC preemption on both sharing parties is balanced, ensuring the eMBB throughput and URLLC reliability in the shared networking eMBB and URLLC multiplexing situation, improving the multiplexing efficiency, and enhancing the eMBB and URLLC user experience under the 5G SA co-construction and sharing 200M shared carrier, which is conducive to the implementation and promotion of the 5G SA 200M shared carrier technology solution.

[0073] Intelligently and customarily control URLLC user traffic diversion at each base station. When downlink resources are congested, existing or newly added URLLC users in the current NR cell are reselected to another shared network. Operators can dynamically allocate the proportion of URLLC users accessing and residing, improving spectrum utilization and ensuring that services for eMBB and URLLC users in the current cell are not reduced due to resource congestion, thereby reducing the impact of limited base station resources on the user experience. SA shared network wireless resources are fully utilized to quickly and effectively balance network loads, while ensuring the performance of remaining users and bearers within the congestion threshold.

[0074] Figure 4 A flow chart showing a method for adjusting the uplink time-frequency resources seized by URLLC services in some embodiments of the present disclosure is shown.

[0075] like Figure 4As shown, the method of this embodiment includes steps 410-430.

[0076] In step 410, in a scenario where the URLLC terminal can seize the uplink time-frequency resources allocated to the eMBB terminal, a second frequency number of uplink sending cancellation indications occurring within a certain period of time at the frequency point of the first sharing party is counted.

[0077] Since the uplink sending cancellation indication can be carried by DCI formats 2-4, this step may, for example, count the second frequency of DCI formats 2-4 appearing within a certain period of time at the frequency point of the first sharing party.

[0078] The first sharing party and the subsequent second sharing party are, for example, different operators. The networking mode of the first sharing party and the second sharing party is: the access network is jointly built and shared, and the core network is independent.

[0079] At step 420, the second frequency is compared with a second correlation threshold.

[0080] In some embodiments, the second correlation threshold includes a second upper threshold and a second lower threshold, but is not limited to the examples given. For example, the second correlation threshold may also include a threshold.

[0081] In step 430, based on the comparison result of the second frequency and the second related threshold, the URLLC terminal that meets the preset conditions is reselected to the frequency point of the second sharing party with the same coverage.

[0082] In some embodiments, when the second related threshold includes a second upper threshold and a second lower threshold, if the second frequency is greater than or equal to the second upper threshold, at least part of the URLLC terminals with no business residing on the first sharing party are reselected to the frequency of the second sharing party with the same coverage (step 431); or, if the second frequency is less than the second upper threshold and greater than the second lower threshold, the new URLLC terminal is controlled to access the frequency of the second sharing party with the same coverage (step 432); or, if the second frequency is less than or equal to the second lower threshold, the URLLC terminal residing on or accessing the first sharing party is allowed to preempt the uplink time-frequency resources allocated to the eMBB terminal, that is, the URLLC business preemption strategy is not adjusted for the time being, and monitoring continues (step 433).

[0083] In some embodiments, when the second related threshold includes a threshold, if the second frequency is greater than or equal to the threshold, at least part of the URLLC terminals with no business residing in the first sharing party will be reselected to the frequency of the second sharing party with the same coverage, or the new URLLC terminals will be controlled to access the frequency of the second sharing party with the same coverage; if the second frequency is less than the threshold, the URLLC terminals residing in or accessing the first sharing party are allowed to preempt the downlink time and frequency resources allocated to the eMBB terminal, that is, the URLLC business preemption strategy will not be adjusted for the time being, and monitoring will continue.

[0084] By adjusting the URLLC preemption scheme for uplink time and frequency resources, the frequency of URLLC preemption on both sharing parties is balanced, ensuring the eMBB throughput and URLLC reliability in the shared networking eMBB and URLLC multiplexing situation, improving the multiplexing efficiency, and enhancing the eMBB and URLLC user experience under the 5G SA co-construction and sharing 200M shared carrier, which is conducive to the implementation and promotion of the 5G SA 200M shared carrier technology solution.

[0085] Intelligently and customarily controls URLLC user traffic diversion at each base station. When uplink resources are congested, existing or newly added URLLC users in the current NR cell are reselected to another shared network. Operators can dynamically allocate the proportion of URLLC users accessing and residing, improving spectrum utilization and ensuring that services for eMBB and URLLC users in the current cell are not reduced due to resource congestion, thereby minimizing the impact of limited base station resources on the user experience. SA shared network radio resources are fully utilized to quickly and effectively balance network loads, while ensuring the performance of remaining users and bearers within the congestion threshold.

[0086] Those skilled in the art will understand that Figure 3 and Figure 4 The methods shown can also be executed jointly, that is, the adjustment method of URLLC service preempting downlink time-frequency resources and uplink time-frequency resources is executed at the same time, which will not be repeated here.

[0087] 5G has a high operating frequency band, and more base stations are deployed under the same coverage, resulting in higher power consumption (about three times that of 4G). In order to build 5G base stations at low cost and high efficiency, it is inevitable to build and share with other operators. URLLC is generally a bursty data transmission. If resources are fixedly reserved for it, it will cause a waste of resources when there is no URLLC data to be transmitted. Therefore, when URLLC and eMMB scenarios are concurrent, URLLC is usually used to seize eMMB resources for transmission. The adjustment scheme disclosed in the present invention can be applied to the 200M SA network sharing of different communication operators to ensure the eMBB and URLLC user experience of different operators. In some 200M SA sharing scenarios, such as congested sections of road for autonomous driving vehicles, URLLC seizes a large amount of eMBB resources. In this scenario, the adjustment scheme disclosed in the present invention controls the proportion of URLLC user access and residence, which can make good use of shared resources, balance users, and avoid accidents.

[0089] The statistical module 510 is configured to count the first frequency number of downlink resource preemption indications that appear within a certain period of time at the frequency point of the first sharing party in a scenario where the URLLC terminal is able to preempt the downlink time-frequency resources that have been allocated to the eMBB terminal; or, to count the second frequency number of uplink sending cancellation indications that appear within a certain period of time at the frequency point of the first sharing party in a scenario where the URLLC terminal is able to preempt the uplink time-frequency resources that have been allocated to the eMBB terminal.

[0090] The comparison module 520 is configured to compare the first frequency with a first correlation threshold; or to compare the second frequency with a second correlation threshold.

[0091] The reselection control module 530 is configured to reselect the URLLC terminal that meets the preset conditions to the frequency point of the second sharing party with the same coverage based on the comparison result of the first frequency and the first related threshold; or, to reselect the URLLC terminal that meets the preset conditions to the frequency point of the second sharing party with the same coverage based on the comparison result of the second frequency and the second related threshold.

[0092] In some embodiments, the reselection control module 530 includes a first reselection control unit 531, which is configured to: when the first relevant threshold includes a first upper threshold and a first lower threshold, if the first frequency number is greater than or equal to the first upper threshold, at least part of the URLLC terminals with no business residing on the first sharing party will be reselected to the frequency point of the second sharing party with the same coverage; or, if the first frequency number is less than the first upper threshold and greater than the first lower threshold, control the new URLLC terminal to access the frequency point of the second sharing party with the same coverage; or, if the first frequency number is less than or equal to the first lower threshold, allow the URLLC terminal residing on or accessing the first sharing party to preempt the downlink time-frequency resources allocated to the eMBB terminal.

[0093] In some embodiments, the reselection control module 530 includes a second reselection control unit 532, which is configured to: when the second related threshold includes a second upper threshold and a second lower threshold, if the second frequency number is greater than or equal to the second upper threshold, reselect at least part of the URLLC terminals with no business performing and residing on the first sharing party to the frequency point of the second sharing party with the same coverage; or, if the second frequency number is less than the second upper threshold and greater than the second lower threshold, control the new URLLC terminal to access the frequency point of the second sharing party with the same coverage; or, if the second frequency number is less than or equal to the second lower threshold, allow the URLLC terminal residing on or accessing the first sharing party to preempt the uplink time-frequency resources allocated to the eMBB terminal.
