Description

A wireless resource scheduling method and device

technical field

The present application relates to the field of communication technologies, and in particular to a radio resource scheduling method and device.

Background technique

With the rapid development of wireless communication technology, the fourth generation (4th ^Generation , 4G) wireless communication network will cover long-term evolution (Long Term Evolution, LTE), wireless local area network (Wireless Local Area Networks, WLAN), cellular network, etc. access technology, and, in order to improve the capacity of the communication system and the call quality of users, in addition to deploying traditional macro (Macro) base stations in each cell, it can also be deployed in a location where the communication signal of the cell is relatively weak, such as the edge of the cell Micro (Pico) base stations and/or Femto base stations. These base stations can be called access points (Access Point, AP), and user equipment (User Equipment, UE) can access these APs based on the above-mentioned multiple access technologies. Provide wireless communication services, thereby forming a multi-level, multi-coverage, multi-access, multi-cooperation 4G heterogeneous wireless communication network.

In the scenario of a 4G heterogeneous wireless communication network, LTE defines multiple downlink transmission modes (Transmission Mode, TM) for the multi-antenna technology of the Physical Downlink Shared Channel (PDSCH). It is a design optimization for a typical AP deployment and channel scenario, and clarifies the downlink data transmission method between AP and UE. Due to the emergence of multiple transmission modes, the transmission relationship of wireless communication data has developed from the traditional single AP to single UE to multiple APs to multiple UEs, thus bringing many problems to wireless resource management in the communication network.

Generally, when radio resource management is performed, the scheduling entity may schedule and allocate radio resources to UEs within the range of multiple APs in a unified and centralized manner. Among them, the multiple APs constitute a scheduling set, and the smallest unit of wireless resource scheduling is called Schedule Resource (Schedule Resource, SRES), and SRES represents the corresponding wireless resource block, and the wireless resource block mainly includes Physical Resource Block (Physical Resource Block, PRB ) and resource block group (Resource Block Group, RBG), each PRB can contain multiple subcarriers in the frequency domain, and can contain multiple codewords in the time domain, and each RBG can be composed of multiple PRBs.

In the prior art, for the scenario of a single AP pairing a single UE, the scheduling entity generally uses a round-robin scheduling algorithm to schedule wireless resources. Probability occupies wireless resources, ensuring fairness. However, in the multi-AP to multi-UE scenario, multiple UEs may be bound together to use the same SRES (the scheduling entity will treat the bound UEs as a whole to allocate SRES, and such a The whole is called a transmission group), and each bound UE may change in each scheduling cycle, in this case, using the round-robin scheduling algorithm may not be able to fairly schedule and allocate radio resources to each UE.

Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

Fig. 1 is the radio resource scheduling process that the embodiment of the present application provides, specifically comprises the following steps:

S101: For a scheduling set, acquire the scheduling priority of each transmission group in the scheduling set, where a transmission group includes at least one user equipment.

In the embodiment of the present application, the wireless resource scheduling process is described by taking the scenario of a 4G heterogeneous wireless communication network as an example. Of course, the wireless resource scheduling method provided in the embodiment of the present application can also be used in some other Scenario for wireless communication network.

In a 4G heterogeneous wireless communication network, there may be multiple macro base stations, micro base stations and even home base stations working together to provide communication services for UEs within the network range. These base stations can be called access nodes (APs). The wireless resource scheduling may be performed by the AP or the scheduling entity on the AP, and the scheduling resource (SRES) is allocated for each user equipment (UE). The scheduling entity may be responsible for the wireless resource scheduling in the corresponding scheduling set, wherein the scheduling set Contains one or more APs, these APs can be coordinated and scheduled in a unified manner, and each AP may contain multiple UEs. Since LTE/LTE-A defines a variety of downlink transmission modes for the multi-antenna technology of the physical downlink shared channel (PDSCH), the transmission relationship of wireless communication data in the network is not only the traditional single AP to single UE, but also single AP to multiple UEs, multiple APs to single UE, and multiple APs to multiple UEs. The following table 1 shows the downlink transmission mode of LTE/LTE-A:

Table 1

Wherein, DCI is downlink control information (Downlink Control Information, DCI), and it can be seen that Table 1 shows a total of 10 downlink transmission modes from TM1 to TM10.

Figures 2 to 5 respectively show application scenarios of the four transmission types of single AP to single UE, single AP to multiple UEs, multiple APs to single UE, and multiple APs to multiple UEs. Among them, the scheduling resource SRES is RBG. Figure 2 shows the application scenario of SU-MIMO transmission type, which is multi-antenna data transmission from a single AP to a single UE. UE occupies RBG alone, and the transmission modes used can be TM2, TM3 and TM8 etc.; Figure 3 shows the application scenario of the MU-MIMO transmission type, which is the multi-antenna data transmission from a single AP to multiple UEs, and each paired and bound UE shares the same RBG, and the transmission mode used can be TM5; Figure 4 uses Pico UE1 shows the application scenario of SU-CoMP transmission type, which is the multi-antenna data transmission of multiple APs to a single UE. CoMP APs and UEs share the same RBG, and the transmission mode used can be TM10; Figure 5 shows MU-CoMP The application scenario of the transmission type is multi-antenna data transmission from multiple APs to multiple UEs, and CoMP APs and UEs share the same RBG. Among them, MIMO is Multiple Input Multiple Output (Multiple Input Multiple Output), CoMP is Coordinated Multiple Points (CoMP), Macro eNB is macro base station, and Pico eNB is micro base station.

In this embodiment of the present application, the scheduling entity performs a round of radio resource scheduling for its corresponding scheduling set in each scheduling period. Generally, the scheduling period may be the length of one radio frame, that is, 10 milliseconds. The scheduling set can be divided into multiple transmission groups according to the APs and UEs in the scheduling set in advance, where the UEs that are bound together to share the SRES and the corresponding APs are divided into the same transmission group, and each transmission group The transmission modes of the APs and UEs are the same, the UEs in different transmission groups are different, and the APs in different transmission groups may be the same.

Further, for the scheduling set, after the scheduling set is divided into multiple transmission groups, the relevant information of UE and AP in each transmission group can be obtained, and the scheduling priority of each transmission group can be obtained, wherein, the The above-mentioned scheduling priority may be pre-set for the transmission group, or the scheduling priority data at the end of the previous scheduling period may be used. The scheduling entity can subsequently perform radio resource scheduling according to the scheduling priority of each transmission group.

S102: Allocate scheduling resources for user equipment included in each transmission group according to the scheduling priority of each transmission group.

In this embodiment of the present application, in each scheduling period, the scheduling entity can allocate SRES to UEs included in each transmission group according to the scheduling priority of each transmission group in the scheduling set, wherein the transmission group with higher scheduling priority The priority is allocated to the corresponding SRES. Obviously, the SRES allocated to the transmission group should be the SRES owned by the AP in the transmission group.

S103: Update the scheduling priority of each transmission group according to the scheduling resource allocation result.

During the radio resource scheduling process, the scheduling priority of each transmission group can be updated according to a set policy. In this embodiment of the application, after each SRES of the set number or set group is allocated, the scheduling priority of each transmission group can be updated respectively, and the scheduling priority of the transmission group that has been allocated the SRES can be updated once. reduce, and at the same time increase the scheduling priority of the transmission group that has not been allocated SRES, similarly, the scheduling priority of the transmission group that has been allocated more SRES can also be reduced, and at the same time, the scheduling priority of the transmission group that has been allocated less SRES The scheduling priority is increased, so that when the SRES is allocated next time, the SRES can be preferentially allocated to the UE in the transmission group that has been allocated less SRES.

Through the above method, for a scheduling set, since the scheduling entity of the scheduling set can, in each scheduling period, according to the SRES allocation results that have occurred, according to the set strategy, the scheduling priorities of each transmission group in the scheduling set can be timely and respectively Therefore, the radio resources can be allocated to each UE in the scheduling set in a fair manner.

In the embodiment of the present application, in the above steps S102 and S103, according to the scheduling priority of each transmission group, the user equipment included in each transmission group is allocated radio resource blocks, and according to the radio resource block allocation results, each transmission group The scheduling priority of each AP is updated, specifically including: numbering the SRESs of each AP in the scheduling set, wherein the same SRES numbers of each AP are the same, and then, for each number, according to the scheduling priority of each transmission group , allocate the numbered SRES to the UEs contained in each transmission group, and each time after a numbered SRES is allocated, the scheduling priority of each transmission group can be adjusted according to the allocation result of the numbered SRES One update.

It should be noted that the same SRES means that the radio resource blocks represented by the SRES are the same, that is, the subcarriers and codewords contained in the radio resource blocks represented by the SRES are the same, and in the scheduling set, the SRESs of the same AP are different. The same, but different APs may have the same SRES, therefore, when numbering the SRES, the same SRES may be numbered the same. An integer 1 to tm_num may be used as the number of the SRES, where tm_num is the total number of different SRESs.

In a scheduling period, the scheduling entity may sequentially allocate the SRESs of each number respectively, and the scheduling period ends after all the SRESs of the numbers are allocated. The scheduling priority of each transmission group can be expressed by parameters, for example, it can be represented by the SCH_Value parameter. In this case, initially, the SCH_Value parameters of each transmission group can be set to 0, that is, at this time, each transmission group The scheduling priority of each transmission group is the same, and then, in each subsequent scheduling cycle, the SCH_Value parameter of each transmission group will be updated (reassigned), that is, the scheduling priority of each transmission group will be updated.

Of course, in practical applications, in addition to adopting the above scheduling priority update method: after allocating a number of SRES, the scheduling priority of each transmission group can be updated once according to the allocation result of this number of SRES . According to different setting strategies, other scheduling priority update methods can also be used. For example, after allocating the set number of SRES or the set number of SRES, or every time a set time interval passes, the The scheduling priority of each transmission group is updated once.

Further, in the above step S102, according to the scheduling priority of each transmission group, assign the numbered SRES to the UEs contained in each transmission group, specifically including: according to the order of scheduling priority from high to low, sequentially target Each transmission group executes: According to the AP corresponding to the transmission group, among the SRES of the number, assign the SRES that has not been allocated and belongs to the AP corresponding to the transmission group to the UE in the transmission group. If the SRES is allocated and belongs to the AP corresponding to the transmission group, the allocation of the SRES to the UE in the transmission group fails.

Obviously, assuming that there are the same APs in the two transmission groups, when assigning an SRES of a certain number of APs, the transmission group with a higher priority in the two transmission groups can be allocated the SRES of this number of the AP, and then, Since the SRES with this number of the AP has already been allocated, for the transmission group with a lower priority, the SRES with this number of the AP will fail to be allocated.

In the embodiment of this application, after each transmission group is assigned a numbered SRES, some UEs in the scheduling set are assigned the numbered SRES, while the other part of the UEs are not assigned the numbered SRES, and each transmission group There may be one or more UEs. Therefore, the scheduling priority of each transmission group may be updated subsequently according to the result of allocating SRES to UEs in each transmission group. In practical applications, the scheduling priority of each transmission group can be updated by comprehensively considering the results of multiple allocations of SRES by the UE in the past. Therefore, at the beginning, the scheduling representation value of the UE can be preset for each UE. Among them, the UE's The scheduling characteristic value can be given a specific meaning to indicate the degree of successfully allocating SRES to the UE. Specifically, the more times the SRES is successfully allocated to the UE, the higher the degree of successfully allocating SRES to the UE. The greater the scheduling characteristic value of the UE is.

For example, the following meaning may be given to the UE's scheduling characteristic value: indicating the number of times the SRES is successfully allocated to the UE. The UE's scheduling characterization value can be represented by the RR_Value parameter, and each time a transmission group is assigned an SRES, the scheduling characterization value of the UE in the transmission group can be updated according to the result of the SRES allocation, that is, the transmission group The RR_Value parameter of the UE is updated.

Specifically, the following formula can be used to update the RR_Value parameter of the UE:

RR_value _success = RR_value+1;

RR_value _fail = RR_value+0;

Among them, RR_value _success is the updated RR_value parameter when the SRES is allocated to the UE successfully;

RR_value _fail is the updated RR_value parameter when the SRES allocation for the UE fails.

It should be noted that the above formula is based on the precondition that the scheduling representation value, that is, the RR_Value parameter indicates the number of times the SRES is successfully allocated to the corresponding UE.

In practical applications, other meanings can also be given to the UE's scheduling characterization value to reflect the extent to which the UE is successfully allocated an SRES, so that when the UE is successfully allocated an SRES, the UE's scheduling characterization value will increase after being updated, as When the UE fails to allocate the SRES, the scheduling representation value of the UE remains unchanged or decreases after the update.

Correspondingly, the above formula for updating the RR_Value parameter may be expressed in other forms, including but not limited to the following expressions:

RR_value _success = a×RR_value+b;

RR_value _fail = c×RR_value+d;

Among them, a, b, c, and d are all constants, RR_value _success > RR_value, and RR_value _fail ≤ RR_value.

Further, in order to ensure the fairness of wireless resource scheduling, when the UE in the transmission group is successfully allocated with SRES more times, the scheduling priority of the transmission group can be updated to be lower, so that the UE in the subsequent transmission group can be reduced. Probability of being successfully assigned an SRES again.

Therefore, in the above step S103, after each allocation for a numbered SRES, the scheduling priority of each transmission group is updated once according to the allocation result for the numbered SRES, specifically including: each time for a numbered SRES After the SRES is allocated, the scheduling priority of each transmission group is updated once according to the updated scheduling characterization value of each UE, wherein, for a pending transmission group, the updated scheduling characterization value of each UE included in the pending transmission group The larger the sum is, the lower the scheduling priority of the pending transmission group is updated.

According to the above description, the formula used to update the scheduling priority of the transmission group includes but not limited to the following expressions:

$\mathrm{<span\; class="notranslate">\; SCH</span>}<span\; class="notranslate">\; \_</span>{\mathrm{<span\; class="notranslate">\; value</span>}}^{<span\; class="notranslate">\; \&prime;</span>}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; m</span>}}{\mathrm{<span\; class="notranslate">\; no</span>}<span\; class="notranslate">\; +</span>\mathrm{<span\; class="notranslate">\; l</span>}<span\; class="notranslate">\; \&times;</span>\underset{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; \&Element;</span>\mathrm{<span\; class="notranslate">\; tm</span>}}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}\mathrm{<span\; class="notranslate">\; RR</span>}<span\; class="notranslate">\; \_</span>\mathrm{<span\; class="notranslate">\; value</span>}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; )</span>}<span\; class="notranslate">\; ;</span>$

Among them, SCH_Value' represents the scheduling priority after the transmission group is updated;

Indicates the sum of the RR_Value parameters of each UE in the transmission group;

m, n, and l are preset constants greater than 0, for example, m=n=l=1 may be preset.

It can be seen that SCH_Value' with is inversely proportional, so that the probability of each UE obtaining the SRES can be dynamically balanced.

According to the above description, the detailed process of wireless resource scheduling provided by the embodiment of the present application is shown in FIG. 6, which specifically includes the following steps:

S601: Initialize the scheduling entity.

During the initialization process of the scheduling entity, firstly, each UE in the scheduling set corresponding to the scheduling entity can be numbered and a UE list can be established for subsequent processing. For example, an integer 1 to ue_num can be used to number each UE, where ue_num can be The total number of UEs in the scheduling set.

Then, the scheduling set may be divided into multiple transmission groups according to the transmission modes of each UE and each AP in the scheduling set, wherein UEs and APs with the same transmission mode belong to the same transmission group. Furthermore, each divided transmission group can also be numbered and a transmission group list can be established to facilitate subsequent processing. For example, an integer 1 to tm_num can be used to number each transmission group, where tm_num can be the transmission group in the scheduling set The total number of , obviously, tm_num<ue_num.

The SRESs in the scheduling set may also be numbered by integers 1 to sres_num, wherein SRESs with the same number represent the same radio resource block, and sres_num is the total number of SRES numbers. Of course, in practical applications, the SRES may not be numbered when the scheduling entity is initialized, but the SRES may be numbered in the subsequent scheduling process.

S602: Determine whether all the SRESs of the APs in the scheduling set are allocated, if yes, perform step S603, otherwise, perform step S604.

S603: End this wireless resource scheduling process.

S604: Select an unallocated SRES number.

S605: According to the scheduling priority of each transmission group, sort each transmission group in descending order of scheduling priority, and start traversing each transmission group to allocate the SRES of the number.

S606: Determine whether each transmission group has been traversed, if yes, execute step S607, otherwise, execute step S608.

S607: Update the scheduling priority of each transmission group according to the scheduling representation value of the UE in each transmission group, and then perform step S602.

S608: Select the next transmission group of the current transmission group.

S609: Allocate the numbered SRES for the selected transmission group.

S610: Determine whether the SRES is allocated successfully, if yes, execute step S611, otherwise execute step S612.

S611: Update the scheduling representation value of each UE in the transmission group according to the update formula corresponding to the successful allocation of the SRES, and then perform step S606.

S612: Update the scheduling representation value of each UE in the transmission group according to the update formula corresponding to the SRES allocation failure, and then perform step S606.

In addition, it should be noted that, in some application scenarios, for each UE, multiple service flows included in the UE can also be assigned scheduling resources respectively. In this case, each UE on the UE can Each service flow maintains a scheduling characterization value. Correspondingly, when updating the scheduling priority of a transmission group, the scheduling priority of the transmission group can be updated according to the scheduling characterization values of multiple service flows of UEs in the transmission group. , so that the fairness of wireless resource scheduling can be guaranteed.
