Description

Technical Field

[0001] This invention relates to the field of wireless network technology, and specifically to a method and apparatus for scheduling bandwidth based on uplink quality. Background Technology

[0002] 5G New Radio Access (5G NR) introduces the Bandwidth Part (BWP) feature. Its purpose is to ensure that User Equipment (UE) can use different operating bandwidths in different states, thereby saving terminal power consumption and allowing for rapid and dynamic adjustment of network configuration to adapt to service changes. It also enables UEs with limited bandwidth capabilities to operate in cells with large system bandwidth. Each BWP consists of a continuous physical resource block (PRB), and its bandwidth, frequency domain location, sub-channel spacing (SCS), and cyclic prefix (CP) length can be flexibly configured to meet different requirements.

[0003] BWPs are divided into initial BWPs, used during the initial access phase and when the terminal is in RRC_IDLE and RRC_INACTIVE states; and dedicated BWPs, used when the terminal is in RRC_CONNECTED state. The relevant configuration information is determined by the network and indicated to the terminal. The terminal obtains initial access BWP information by reading cell system information. In connected state, the terminal performs BWP handover via DCI indication or by the expiration of the BWP inactivity timer (BWP-InactivityTimer) and Radio Resource Control (RRC) signaling.

[0004] While the 3GPP specification defines the flexibility of configuring different BWPs for each UE, this flexibility also increases the complexity of processing and scheduling for the network. Therefore, currently, the network may only configure BWPs separately for specific users (e.g., low-bandwidth terminals or special industry terminals), while using the same BWP configuration for a large number of ordinary users. It's even possible that for scheduling convenience, only one full-bandwidth BWP is configured in RRC connected state. This can easily lead to a mismatch between the network-configured / activated BWP and the terminal state, which may severely impact terminal performance and user experience, especially for terminals in special states. Current BWP handover mechanisms are not entirely clear; most proposed BWP handover mechanisms involve simultaneous uplink and downlink handover. Furthermore, most BWP handover strategies lack corresponding adjustment measures after handover to adapt to the new BWP. Summary of the Invention

MCS Thr is the threshold value for the modulation and coding strategy index. BLER Thr is the block error rate threshold. PHR The power margin reporting threshold; if the modulation and coding strategy index value I MCSIf the block error rate (BLER) and the power margin report (PHR) meet the first preset condition, then it is determined that the resources of the uplink bandwidth portion need to be scheduled.

[0008] In one alternative approach, the continuous adjustment of the uplink bandwidth portion based on the current uplink bandwidth portion, signal-to-noise ratio (SNR), and quality of service includes: determining a target SNR when the block error rate is a block error rate threshold; continuously adjusting the bandwidth of the uplink bandwidth portion based on the current SNR and the target SNR, and reserving the scheduling of some quality of service services.

[0010] In one optional approach, determining a first minimum positive integer based on the current signal-to-noise ratio (SINR) and the target SINR, and adjusting the bandwidth of the uplink bandwidth portion and the scheduling of the reserved quality-of-service (QoS) portion based on the first minimum positive integer, includes: determining the bandwidth of the uplink bandwidth portion and the scheduling of the reserved QoS portion based on the current SINR and the target SINR. tar Determine the first minimum positive integer N0 that satisfies the first relation: SINR + 3N ≥ SINRtar, where N is a positive integer; adjust the bandwidth of the uplink bandwidth portion to BWP / N0 according to the first minimum positive integer N0, where BWP is the uplink bandwidth portion; according to the scheduling priority of the Quality of Service (QoS), retain the scheduling of QoS services that meet the second preset condition from high to low: Among them, BSR i For QoS i The uplink service cache; S is the set of all QoS, and R is a subset of S with scheduling priority from high to low that satisfies the second relation.

[0011] In one alternative approach, the step of updating the first minimum positive integer if the adjusted detected block bit error rate is greater than the target block bit error rate, and repeatedly adjusting the bandwidth of the uplink bandwidth portion and the scheduling of the reserved portion of quality of service based on all the first minimum positive integers, includes: if the adjusted detected block bit error rate is greater than the target block bit error rate, then: based on the current signal-to-noise ratio (SINR) and the target SINR... tar Determine the first minimum positive integer N that satisfies the first relation for the i-th adjustment. i Adjust the bandwidth of the uplink bandwidth portion to BWP / ΠN based on all the first minimum positive integers. i Update the second preset condition based on all of the first minimum positive integers: According to the scheduling priority of the Quality of Service (QoS), services that meet the updated second preset conditions are retained in the scheduling process from high to low.

[0012] In one alternative approach, the step of updating the second minimum positive integer if the adjusted detected block bit error rate is less than the target block bit error rate, and repeatedly adjusting the bandwidth of the uplink bandwidth portion and the scheduling of the reserved portion of quality of service based on all the first minimum positive integers and all the second positive integers, includes: if the adjusted detected block bit error rate is less than the target block bit error rate, then: based on the current signal-to-noise ratio (SINR) and the target SINR... tar Determine the second smallest positive integer M that satisfies the second relation for the i-th adjustment. i SINR-3M≥SINR tar Where M is a positive integer; the bandwidth of the uplink bandwidth portion is adjusted to BWP×ΠM based on all the first minimum positive integers and all the second positive integers. i / ΠN i N i The first minimum positive integer is the value of the i-th adjustment; the second preset condition is updated based on all the first minimum positive integers and all the second positive integers: According to the scheduling priority of the Quality of Service (QoS), services that meet the updated second preset conditions are retained in the scheduling process from high to low.

[0013] According to another aspect of the present invention, a scheduling apparatus for a portion of uplink bandwidth based on uplink quality is provided. The apparatus includes: a status acquisition unit, configured to acquire an uplink status and determine whether to schedule resources of the uplink bandwidth portion based on the uplink status, wherein the uplink status includes at least block error rate and quality of service; a scheduling unit, configured to continuously schedule the uplink bandwidth portion based on the current uplink bandwidth portion, signal-to-noise ratio, and quality of service when scheduling of resources of the uplink bandwidth portion is required; and a stop scheduling unit, configured to stop scheduling the uplink bandwidth portion if the adjusted detected block error rate is equal to the target block error rate.

[0016] According to another aspect of the present invention, a computer storage medium is provided, the storage medium storing at least one executable instruction that causes the processor to perform the steps of the above-described scheduling method for bandwidth portions based on uplink quality.

[0017] This invention, through obtaining the uplink status, determines whether uplink bandwidth resources need to be scheduled based on the uplink status. The uplink status includes at least the block error rate (BOR) and quality of service (QoS). When uplink bandwidth resources need to be scheduled, the uplink bandwidth is continuously scheduled based on the current uplink bandwidth, signal-to-noise ratio (SNR), and QoS. If the adjusted BOR is equal to the target BOR, the scheduling of the uplink bandwidth is stopped. This allows for adjustment of the uplink BWP bandwidth and trade-offs in uplink services, ensuring reliable transmission of higher-priority QoS services in a limited network environment, thus improving user experience.

[0018] The above description is merely an overview of the technical solutions of the embodiments of the present invention. In order to better understand the technical means of the embodiments of the present invention and to implement them in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the embodiments of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

[0019] Various other advantages and benefits will become apparent to those skilled in the art upon reading the following detailed description of preferred embodiments. The accompanying drawings are for illustrative purposes only and are not intended to limit the invention. Furthermore, the same reference numerals denote the same parts throughout the drawings.

[0023] Figure 4 A schematic diagram of the structure of a computing device provided in an embodiment of the present invention is shown. Detailed Implementation

[0024] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0025] Figure 1 This diagram illustrates a flowchart of a bandwidth scheduling method based on uplink quality provided by an embodiment of the present invention. This bandwidth scheduling method based on uplink quality is applied to a base station, such as... Figure 1 As shown, the bandwidth scheduling method based on uplink quality includes:

[0026] Step S11: Obtain the uplink status and determine whether the uplink bandwidth resources need to be scheduled based on the uplink status. The uplink status includes at least the block error rate and quality of service.

[0027] This invention addresses situations where uplink channel quality is poor, such as at cell edges or in the presence of poor uplink channels. Based on modulation and coding scheme (MCS), block error ratio (BLER), power headroom report (PHR), and uplink buffer status for various Quality of Service (QoS) parameters, the bandwidth of the uplink BWP is adjusted. This ensures reliable transmission of higher-priority QoS services through uplink BWP handover, even when channel quality is poor and the UE's uplink transmit power is already at its maximum and cannot be further increased to improve channel quality. This improves user experience.

[0028] In step S11, optionally, the uplink status including the modulation and coding policy index value, the block bit error rate, the power margin reporting, and the quality of service is obtained; the modulation and coding policy index value I is determined. MCS Whether the block error rate (BLER) and the power margin reporting (PHR) are the first preset conditions; if the modulation and coding strategy index value I MCS If the Block Error Rate (BLER) and Power Headroom Reporting Rate (PHR) meet the first preset condition, then it is determined that the resources of the uplink bandwidth portion need to be scheduled. The first preset condition is:

[0029]

[0030] Among them, I MCS For modulation and coding strategy index value, Thr MCS The modulation and coding strategy index threshold value is preferably 2 / 3. BLER The block error rate threshold is preferably 10%. PHR The power margin reporting threshold is preferably 0.

[0031] Uplink status acquisition is real-time. If the modulation and coding strategy index value I... MCS If the Block Error Rate (BLER) and Power Headroom Reporting Rate (PHR) meet the first preset condition, it indicates a problem with the uplink, requiring resource scheduling and adjustment for the uplink bandwidth. Otherwise, no adjustment to the uplink bandwidth is needed.

[0032] Step S12: When it is necessary to schedule the resources of the uplink bandwidth portion, the uplink bandwidth portion is continuously scheduled according to the current uplink bandwidth portion, the signal-to-noise ratio, and the service quality.

[0033] In embodiments of the present invention, optionally, such as Figure 2 As shown, it includes:

[0034] Step S121: Determine the target signal-to-noise ratio when the block error rate is the block error rate threshold.

[0035] Block error rate is the block error rate threshold Thr. BLER At that time, the corresponding target signal-to-noise ratio (SINR) is obtained. tar The target signal-to-noise ratio is the uplink signal-to-noise ratio of the terminal.

[0036] Step S122: Continuously adjust the bandwidth of the uplink bandwidth portion and the scheduling of the reserved quality of service services based on the current signal-to-noise ratio and the target signal-to-noise ratio.

[0037] The current signal-to-noise ratio (SNR) is the terminal's current uplink SNR. Optionally, in step S122, a first minimum positive integer is determined based on the current SNR and the target SNR, and the bandwidth of the uplink bandwidth portion and the scheduling of reserved quality-of-service (QoS) services are adjusted based on the first minimum positive integer. This is based on the current SNR and the target SNR. tar Determine the first smallest positive integer N0 that satisfies the first relation: SINR + 3N ≥ SINR tar Where N is a positive integer. N0 is the first minimum positive integer obtained that satisfies the first relational expression for initial adjustment. The bandwidth of the uplink bandwidth portion is adjusted to BWP / N0 according to the first minimum positive integer N0, where BWP is the uplink bandwidth portion. According to the scheduling priority of the Quality of Service (QoS), services that satisfy the second preset condition are retained in descending order of priority:

[0038] Among them, BSR i For QoS i The uplink service buffer is defined as follows: S is the set of all QoS levels, and R is a subset of S with scheduling priorities ranked from high to low that satisfy the second relation. This completes the initial scheduling of the uplink bandwidth portion; further scheduling is required based on the scheduling results.

[0039] If the adjusted detected block bit error rate is greater than the target block bit error rate, then the first minimum positive integer is updated, and the bandwidth of the uplink bandwidth portion and the scheduling of the reserved portion of quality of service are repeatedly adjusted based on all the first minimum positive integers. If the adjusted detected block bit error rate is greater than the target block bit error rate, then based on the current signal-to-noise ratio (SINR) and the target SINR... tar Determine the first minimum positive integer N that satisfies the first relation for the i-th adjustment. i Adjust the bandwidth of the uplink bandwidth portion to BWP / ΠN based on all the first minimum positive integers. iUpdate the second preset condition based on all of the first minimum positive integers: According to the scheduling priority of the Quality of Service (QoS), services that meet the updated second preset conditions are retained in the scheduling process from high to low.

[0040] If the adjusted detected block bit error rate is less than the target block bit error rate, then the second minimum positive integer is updated, and the bandwidth of the uplink bandwidth portion and the scheduling of the reserved portion of quality of service are repeatedly adjusted based on all the first minimum positive integers and all the second positive integers. If the adjusted detected block bit error rate is equal to the target block bit error rate, then the current signal-to-noise ratio (SINR) and the target SINR are adjusted accordingly. tar Determine the second smallest positive integer M that satisfies the second relation for the i-th adjustment. i SINR-3M≥SINR tar Where M is a positive integer. The bandwidth of the uplink bandwidth portion is adjusted to BWP×ΠM based on all the first minimum positive integers and all the second positive integers. i / ΠN i N i Let be the first smallest positive integer in the i-th adjustment. Update the second preset condition based on all the first smallest positive integers and all the second positive integers: According to the scheduling priority of the Quality of Service (QoS), services that meet the updated second preset conditions are retained in the scheduling process from high to low.

[0041] After each scheduling, reliable transmission of QoS services in subset R is guaranteed. Thus, for the user's uplink, when it is determined that the user's uplink cannot be guaranteed, the uplink BWP bandwidth is adjusted, and uplink services are prioritized, ensuring only some high-priority QoS services are guaranteed. This is to meet the needs of high-priority services in a limited network environment, rather than leaving all services unreliable.

[0042] Step S13: If the adjusted detected block bit error rate is equal to the target block bit error rate, then stop scheduling the uplink bandwidth portion.

[0043] According to step S12, the uplink bandwidth portion is continuously scheduled until the adjusted block error rate is detected to be equal to the target block error rate. Then, the scheduling of the uplink bandwidth portion is stopped, thus completing this round of scheduling of the uplink bandwidth portion.

[0044] In subsequent work, the uplink status is acquired in real time. If the uplink status indicates that the first preset condition is met, the scheduling is re-performed according to steps S12-S13.

[0045] This invention, through obtaining the uplink status, determines whether uplink bandwidth resources need to be scheduled based on the uplink status. The uplink status includes at least the block error rate (BOR) and quality of service (QoS). When uplink bandwidth resources need to be scheduled, the uplink bandwidth is continuously scheduled based on the current uplink bandwidth, signal-to-noise ratio (SNR), and QoS. If the adjusted BOR is equal to the target BOR, the scheduling of the uplink bandwidth is stopped. This allows for adjustment of the uplink BWP bandwidth and trade-offs in uplink services, ensuring reliable transmission of higher-priority QoS services in a limited network environment, thus improving user experience.

BLER Thr is the block error rate threshold.

[0053] SINR+3N≥SINR tar Where N is a positive integer;

[0054] The bandwidth of the uplink bandwidth portion is adjusted to BWP / N0 based on the first minimum positive integer N0, where BWP is the uplink bandwidth portion;

[0055] According to the scheduling priority of the Quality of Service (QoS), services that meet the second preset condition are retained in descending order of priority:

[0056] Among them, BSR i For QoS i The uplink service cache; S is the set of all QoS, and R is a subset of S with scheduling priority from high to low that satisfies the second relation.

[0059] This invention, through obtaining the uplink status, determines whether uplink bandwidth resources need to be scheduled based on the uplink status. The uplink status includes at least the block error rate (BOR) and quality of service (QoS). When uplink bandwidth resources need to be scheduled, the uplink bandwidth is continuously scheduled based on the current uplink bandwidth, signal-to-noise ratio (SNR), and QoS.
