Description

Technical Field

[0001] The present invention belongs to the field of communication resource scheduling, and in particular relates to a resource joint scheduling method, system, storage medium and electronic equipment. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The International Telecommunication Union (ITU) has defined three major application scenarios based on the diverse service quality requirements of 5G wireless network systems (such as coverage, data rate, latency, and reliability), namely enhanced mobile broadband (eMBB), ultra-reliable and low-latency communications (URLLC), and massive machine type communications (mMTC). eMBB is an extension of the existing mobile broadband scenario, with the goal of maximizing the data rate of a stable connection over a period of time while ensuring moderate reliability, with a packet error rate (PER) of about 10 -3 Typical applications of URLLC include smart grid, factory automation, drone control, autonomous driving, and key medical device management. Therefore, the transmission rate is relatively low, and the main requirement is to achieve end-to-end millisecond-level low latency while ensuring ultra-high reliability. Although its data packet length is small, the PER is usually less than 10 -5 In addition, URLLC transmission is intermittent, and supporting its transmission requires a high-priority resource scheduling strategy to ensure that there are available communication resources when data packets arrive. Given the significant differences in the service attributes of eMBB and URLLC, how to effectively allocate transmission resources to meet the QoS requirements of various services in the scenario where the two services coexist has become a key issue in promoting the application of 5G in the power industry.

[0004] Based on the design made for the typical scenario of coexistence of these two services in 3GPP R15 and R16 versions, the existing mechanisms can be divided into three types. Considering the strict latency requirements of URLLC, when both services have wireless transmission requirements, the simplest resource allocation mechanism is to reserve a part of the resources for URLLC to ensure that it can be directly transmitted without authorization. However, the reserved resources will be idle due to the intermittent nature of URLLC services, which is not the best solution. The second resource allocation mechanism is superposition scheduling. Similar to the concept of non-orthogonal multiple access, URLLC and eMBB users share time and frequency resources. First, URLLC users with higher latency requirements are decoded, and then continuous interference cancellation technology is used for eMBB users to eliminate known URLLC interference before decoding. Under this mechanism, the rate of eMBB services is almost unaffected, but the interference cancellation capability of the URLLC service receiver is limited and cannot guarantee its ultra-high reliability requirements.

[0005] Compared with the first two mechanisms, the advantages of the puncturing scheduling mechanism are more prominent. At this time, URLLC transmits with a smaller time granularity - micro-time slots, that is, 2 to 7 orthogonal frequency division multiplexing (OFDM) symbols as the transmission time interval. When the frequency resources have been allocated to eMBB users, it is allowed to cancel the original eMBB data transmission on the micro-time slot where the URLLC data packet arrives, and instead carry the URLLC traffic. This scheme will not affect the reliability of the URLLC service, but the disadvantage is that the throughput of the eMBB service will be lost. Therefore, how to reduce the data rate loss caused by puncturing to the eMBB service is the key to the study of the puncturing scheduling problem. For this optimization goal, existing studies have focused on selecting the best puncturing location for the URLLC load to reduce the loss of eMBB user throughput under the premise of a given eMBB user resource allocation scheme through methods such as neural networks, reinforcement learning, or solving optimization problems.

[0006] The inventors found that in the current process of selecting the best puncturing location for URLLC load to reduce the loss of eMBB user throughput, no research has considered the URLLC traffic arrival characteristics, and the rate loss of eMBB is still relatively high. Summary of the invention

[0007] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides a resource joint scheduling method, system, storage medium and electronic device, which considers the characteristics of the URLLC traffic arrival process, combines the rate loss analysis of the eMBB service, associates the allocation of communication resources with the eMBB rate loss function caused by punching, establishes a physical resource block (PRB) allocation model, and optimizes the selection of the URLLC load punching position based on the strategy of minimizing the rate loss of each eMBB user before and after punching.

[0036] Embodiment 1

[0037] like Figure 2 As shown, this embodiment provides a resource joint scheduling method, which specifically includes the following steps:

[0038] S201: Based on the wireless system model, considering the characteristics of the URLLC traffic arrival process and the decoding characteristics of the actual eMBB service, an eMBB rate loss function caused by puncturing is constructed.

[0039] In the wireless system model, if a URLLC data packet arrives, the URLLC data packet is sent using a mini-time slot as the transmission time interval to seize the time and frequency resources of the eMBB service.

[0040] The characteristic of the URLLC traffic arrival process is that the URLLC arrival traffic request of all users in any time slot is equal to the sum of the URLLC loads of all users on all mini-time slots in any time slot.

[0041] Consider a gNB serving a set of eMBB users E = {1, ... |E|} and URLLC arrival traffic request D for the downlink. Its bandwidth is divided into a set of PRBs B = {1, ... |B|}, and each PRB b∈B occupies 12 subcarriers. Within a transmission time T, the transmission time interval of the eMBB service is time slot t, and each time slot consists of |M| micro-time slots m. If a URLLC data packet arrives, the time-frequency resources of the eMBB service are seized to send the URLLC data packet with the micro-time slot as the transmission time interval. The channel state S of the wireless system is expressed by the peak rate of the eMBB user e∈E on the PRB in time slot t. Representation.

[0042] This embodiment is a wireless system downlink containing 100 PRBs, serving 20 eMBB users and URLLC traffic at the same time. Under the channel state of different time slots, the peak rate of the eMBB user on the PRB is a random variable between 1 and 3 Mbps.

[0043] The definition of URLLC traffic in 3GPP is the ftp-3 model, which is a Poisson process with an arrival rate of λ. Let D(t) be the arrival traffic request of URLLC in time slot t. As far as the rate loss of eMBB users is concerned, the specific micro-timeslots and PRBs that are punctured are not important, but the total amount of puncturing is the key. Therefore, let the variable represents the URLLC load of user e∈E in mini-time slot m under channel state s∈S and using scheduling strategy π; variable represents the sum of the URLLC loads of user e in all mini-timeslots in time slot t. According to the relationship between the arrival traffic and the URLLC load after the eMBB user is punched, we can get:

[0044]

[0045] For example, a Poisson process with a URLLC traffic arrival rate of 20 to 400 packets / ms in each time slot is used as a random variable.

[0046] Since eMBB users have certain error correction capabilities during the actual decoding process, the rate loss caused by puncturing is not in a simple linear relationship with the URLLC load. Therefore, a more practical convex function is used to represent the rate loss. Therefore, the rate of user e is:

[0047]

[0048] in is the rate loss function. is the peak rate of user e in time slot t. is the sum of the URLLC loads of user e in all mini-timeslots in time slot t. Indicates whether PRB b in time slot t is allocated to user e when scheduling strategy π is adopted under channel state s:

[0049]

[0050] Considering the actual decoding characteristics of the eMBB service, formula (2) is used as the rate of the eMBB user after puncturing.

[0051] S202: Associating the allocation of communication resources with the eMBB rate loss function caused by puncturing, and establishing a physical resource block allocation model.

[0052] The eMBB rate loss function caused by the puncturing is represented by a convex function. The constraints of the physical resource block allocation model include: PRB allocation restriction constraints, the constraint that the resources occupied by the puncturing do not exceed the total resources allocated to the user itself, and the constraint that all arriving URLLC traffic requests are satisfied without queuing.

[0053] Therefore, the optimization problem can be described as:

[0054]

[0055]

[0056]

[0057]

[0058]

[0059]

[0060] Constraints (5)-(7) are the PRB allocation restrictions. Constraint (8) is to ensure that the resources occupied by puncturing do not exceed the total resources allocated to user e. Constraint (9) ensures that all incoming URLLC traffic requests are satisfied without waiting in queues.

[0061] In order to maximize the objective function in formula (4), the resource allocation strategy of eMBB needs to consider the possible rate impact of URLLC traffic arrival rate on the current time slot compared to the single service scenario. Therefore, the weight of PRB allocated to user e is for:

[0062]

[0063] It consists of two parts: the actual rate of the user in the previous time slot and the expected rate in the current time slot. η is the proportional factor of these two parts, η∈[0,1]. is the actual rate of user e in the (t-1)th time slot under scheduling strategy π. is the peak rate of user e in the tth time slot PRB under channel state s, L π,s (t) is the total URLLC traffic that all users e∈E need to carry in time slot t. When allocating PRBs, the peak rate is selected based on the channel status s of the user in the current time slot t. then and L π,s (t) is substituted into the weight factor The user is allocated PRBs according to the proportion of this weight factor. When PRBb is allocated to user e, let

[0064] The specific process of eMBB resource allocation is as follows:

[0065]

[0066]

[0067] Where loc is an iteration variable used to record the number of allocated PRBs. e,b is the number of PRBs allocated to user e. The eMBB resource allocation considers the arrival characteristics of URLLC traffic, the peak rate under the channel state of the current time slot, and the achieved rate of the previous time slot, and calculates the weight factor of formula (10). The PRB allocation is completed according to Algorithm 1 based on the proportion of this factor.

[0068] S203: Based on the strategy of minimizing the rate loss of each eMBB user before and after puncturing and the physical resource block allocation model, optimize the selection of the URLLC load puncturing position.

[0069] When URLLC traffic arrives in the mini-timeslot, the selection of each puncture position needs to first use formula (2) to calculate the rate loss of all eMBB users before and after the number of punctures is increased.

[0070]

[0071] Then, the user with the smallest rate loss and whose resources occupied by punching do not exceed the total resources allocated to itself is selected for punching.

[0072] Figure 3 This is the puncturing scheduling mechanism for eMBB and URLLC services in this embodiment. Figure 3Slot in it is the transmission time interval, and Mini-slot is the minimum transmission time interval.

[0073] The eMBB service schedules wireless network resources with time slots as the transmission time interval; URLLC traffic arrives at the scheduler with mini-time slots (2 OFDM symbols) as the transmission time interval, and the arrival process follows Poisson distribution. The arriving URLLC traffic will seize the bandwidth transmission of eMBB in the mini-time slot. By allocating wireless network resources to eMBB users and selecting URLLC punching locations, the goal of maximizing all eMBB users and rates can be achieved.

[0074] Figure 4 The URLLC arrival rate and eMBB rate curves obtained after the simulation experiment of the technical solution of this embodiment. In order to highlight the performance of the proposed algorithm (Proposed Algorithm) of this embodiment, two comparison algorithms (punching position optimization algorithm and random puncturing algorithm) are set to simulate at the same time. Among them, the puncturing position optimization algorithm and the random puncturing algorithm correspond to Figure 4 Baseline1 and Baseline2 in . Without considering the URLLC traffic arrival rate, PRBs are allocated based on the rate of the eMBB user in the previous time slot and the peak rate in the current time slot channel state as weight factors, and the URLLC puncturing position selects the eMBB user with the smallest rate loss before and after puncturing (Baseline1); the PRB allocation strategy is the same as Baseline1, but the puncturing position is randomly selected (Baseline2). The results show that as the URLLC traffic arrival rate increases, the eMBB rate loss of the three schemes also gradually increases, but the resource joint scheduling strategy proposed in the present invention has a more moderate rate decrease trend than the puncturing position optimization algorithm and the random puncturing algorithm. When the arrival rate is 400 Packets / ms, the eMBB rate gain of the proposed scheme compared with the puncturing position optimization algorithm is about 6.8%, and the eMBB rate gain compared with the random puncturing algorithm is about 9.1%.

[0075] Figure 5 The empirical cumulative distribution function curves of the eMBB rates under the three schemes are shown in Table 1. The results show that when the URLLC arrival rate is 20-400 Packets / ms, the minimum rate of eMBB is increased by about 16-19 Mbps compared with the puncturing location optimization algorithm and the random puncturing algorithm.

[0079] Among them, in the wireless system model, if a URLLC data packet arrives, the URLLC data packet is sent by seizing the time and frequency resources of the eMBB service with a mini-time slot as the transmission time interval.
