[0114] In this embodiment of the invention, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0115] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0116] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0117] Figure 1 is a flowchart of a method for adjusting a scheduling MCS level according to the first embodiment of the present application, as shown in the figure, the method comprises: Figure 1

[0118] Step 101, obtaining a target data amount to be transmitted by a target user to be scheduled.

[0119] In some possible embodiments, the network side device to which the method for adjusting a scheduling MCS level is applied can be a base station, or can be a device in an access network that communicates with a wireless terminal device through one or more sectors over an air interface.

[0120] In some possible embodiments, the target user to be scheduled can be a user terminal (User Equipment, UE), and the number of target users can be one or more. When the number of target users is more than one, the corresponding target data amount is also more than one, which can be represented by a list DList. wherein, represents the target data amount corresponding to each of the N target users.

[0121] Step 102, determining a position mark of the target user in a scheduling flow based on a non-data domain resource occupation adjustment MCS level according to the target data amount and a preset data amount threshold value.

[0122] In some possible embodiments, a data amount threshold value can be preset, and the target data amount and the data amount threshold value are compared, and according to the comparison result, the position mark of the target user in the scheduling flow based on the non-data domain resource occupation adjustment MCS (Modulation and Coding Scheme) level is determined. The non-data resource includes but is not limited to any one of PT-RS (Phase Tracking Reference Signal) and UCI (Uplink Control Information).

[0123] It should be noted that the comparison method between the target data amount and the data amount threshold value can be adjusted according to different application scenarios, and in some application scenarios, the relationship between the target data amount and the data amount threshold value can be a quantity size relationship, which will be explained in detail as follows:

[0124] If the target data amount is less than the data amount threshold value, it is determined that the MCS level is adjusted based on the non-data domain resource occupation when calculating the frequency domain resource number required by the target user, and the position mark is set to a first mark.​

[0125] If the target data volume is greater than or equal to the data volume threshold value, the MCS level is adjusted based on the non-data domain resource occupation before the scheduling resource allocation completes the issuance of the authorization, the position marker is set to the second identification.

[0126] In some possible embodiments, the step can be represented using variables, specifically:

[0127] Let the current UE be UE i The position marker of the adjustment of the MCS level in the scheduling process is set to ModMCSLoc i The value of the value ranges from {InPRBPreComp, InFinalTBSComp}. InPRBPreComp is the first identification indicating the adjustment of the MCS level when calculating the number of frequency domain resources required by the user; InFinalTBSComp is the second identification indicating the adjustment of the MCS level based on the non-data domain resource occupation before the scheduling resource allocation completes the issuance of the authorization.

[0128] If ModMCSLoc i = InPRBPreComp.

[0129] If ModMCSLoc i = InFinalTBSComp.

[0130] It can be understood that when the target user is multiple, a position marker list ModMCSLocList = {ModMCSLoc1, ModMCSLoc2, …, ModMCSLoc N} can be used to record the position marker corresponding to each target user, wherein ModMCSLoc1, ModMCSLoc2, …, ModMCSLoc N are the position markers corresponding to each target user.

[0131] Step 103, based on the position marker, the MCS level of the target user is adjusted according to a preset strategy.

[0132] In some possible embodiments, some strategies can be preset, and according to the strategy and the position marker, the MCS level of the target user can be adjusted.

[0133] Understandably, the position of MCS level adjustment in the scheduling process will differ depending on the location marker. Based on a preset strategy and considering relevant parameters of the target user, the MCS level of the target user can be adjusted. These relevant parameters include, but are not limited to, any one or more of the following: initial MCS level, initial spectral efficiency, and maximum MCS level.

[0134] The preset strategy can be set according to the specific application scenario. One such preset strategy can be found in the second embodiment of this application.

[0135] The scheduling MCS level adjustment method according to the embodiments of this application obtains the marker position of the adjustment MCS level in the scheduling process based on the target data volume and data volume threshold value, and adjusts the MCS level of the target user according to the marker position and a preset strategy. The method adaptively determines whether the scheduling MCS level needs further adjustment based on the time-frequency domain density information occupied by non-data domain resources, improving the efficiency and accuracy of MCS level adjustment.

[0136] Based on the above embodiments, different strategies can be used to adjust the target user's MCS level according to different application scenarios based on location markers. To illustrate the adjustment process in more detail, step 103 of the above embodiments can be specifically explained through Embodiment 2.

Furthermore, it can increase the MCS... init Compare with 1 to determine if the MCS level has room for adjustment.

[0140] Step 202: If the initial MCS level is greater than or equal to 1, then obtain the initial spectral efficiency corresponding to the initial MCS level.

[0141] When MCS initWhen ≥1, it is determined that the MCS level has adjustment space, and thus the MCS needs to be acquired init The corresponding initial spectral efficiency can be denoted as eff int In some application scenarios, the MCS init The corresponding eff int The acquisition method can include the following steps:

[0142] Step 1: Acquire the corresponding first MCS level by rounding down the initial MCS level.

[0143] In some possible embodiments, the rounding down operation can use denote the first MCS level as MCS 1 This step can be denoted as:

[0146] According to a preset protocol, acquire the maximum MCS level, and acquire the maximum spectral efficiency corresponding to the maximum MCS level based on a protocol MCS level and spectral efficiency correspondence table.

[0147] In some possible embodiments, a protocol can be preset, which records the maximum MCS, denoted as MCS max The protocol also records a MCS level and spectral efficiency correspondence table. According to the table, the maximum spectral efficiency corresponding to the MCS max , denoted as eff max , can be acquired.

[0148] If the first MCS level is less than or equal to the maximum MCS level, determine the first spectral efficiency corresponding to the first MCS level based on the protocol MCS level and spectral efficiency correspondence table.

[0149] In some possible embodiments, when MCS 1 ≤ MCS max , the first spectral efficiency corresponding to the MCS 1 , denoted as eff 1 , can be determined based on the protocol MCS level and spectral efficiency correspondence table.

The first spectrum efficiency corresponding to the first MCS level is determined based on the calculation result.

[0152] The third formula can be: eff 1 =eff max +(MCS 1 -MCS max )*α.

[0153] Among them, eff max MCS represents the maximum spectral efficiency. 1 Indicates the first MCS level, MCS max This indicates the maximum value of the MCS level.

[0154] Step 3: Add 1 to the first MCS level to obtain the corresponding second MCS level.

[0155] In some possible embodiments, the second MCS level can be denoted as MCS. 2 MCS 2 The calculation formula can be used for MCS 2 =MCS 1 +1. Among them, MCS 1 This indicates the first MCS level.

[0156] Step 4: Determine the second spectral efficiency corresponding to the second MCS level.

[0157] In some possible embodiments, the step of determining the second spectral efficiency includes:

[0158] The maximum value of the MCS level is obtained according to the preset protocol, and the maximum value of the spectrum efficiency corresponding to the maximum value of the MCS level is obtained based on the table of MCS level and spectrum efficiency correspondence.

[0159] In some possible embodiments, a preset protocol can be used to record the maximum value of MCS, which can be denoted as MCS. maxThe protocol also records a table mapping MCS levels to spectral efficiency. The MCS can be obtained from this table. max The corresponding maximum spectral efficiency, which can be denoted as eff max .

[0160] If the second MCS level is less than or equal to the maximum value of the MCS level, then the second spectral efficiency corresponding to the second MCS level is determined based on the protocol MCS level and spectral efficiency correspondence table.

[0161] In some possible embodiments, when MCS 2 ≤MCS max At that time, the MCS can be determined based on the table corresponding to the protocol MCS level and spectral efficiency. 2 The corresponding second spectral efficiency, which can be denoted as eff 2 .

[0162] If the second MCS level is greater than the maximum value of the MCS level, the spectrum efficiency configuration parameters are obtained, and the maximum spectrum efficiency, the second MCS level, the maximum value of the MCS level, and the spectrum efficiency configuration parameters are calculated according to the preset fourth formula. The second spectrum efficiency corresponding to the second MCS level is determined based on the calculation results.

[0163] In some possible embodiments, when MCS 2 MCS max At this time, it is necessary to obtain the spectrum efficiency configuration parameter α, and calculate the second MCS level MCS based on the fourth formula for the maximum spectrum efficiency, the second MCS level, the maximum MCS level, and the spectrum efficiency configuration parameter. 2 The corresponding second spectral efficiency eff 2 .

[0164] The fourth formula can be: eff 2 =eff max +(MCS 2 -MCS max )*α.

[0165] Among them, eff max MCS represents the maximum spectral efficiency. 2 Indicates the second MCS level, MCS max This indicates the maximum value of the MCS level.

[0166] Step 5: Calculate the first MCS level, the second MCS level, the first spectral efficiency, the second spectral efficiency, and the initial MCS level according to the preset second formula, and obtain the initial spectral efficiency based on the calculation results.

[0167] In some possible embodiments, the initial spectral efficiency can be denoted as eff, and the initial spectral efficiency eff is calculated according to a second formula based on the first MCS level, the second MCS level, the first spectral efficiency, the second spectral efficiency, and the initial MCS level.

[0168] The second formula can be:

[0170] In step 203, the total number of REs available to the PUSCH allocated to the target user is obtained, and the total number of REs occupied by non-data domain resources on the PRB allocated to the target user under a preset condition is obtained.

[0171] In some possible embodiments, the PRB allocated to the target user is deducted from some overhead, and after the deduction, the total number of REs available to the PUSCH allocated to the target user can be obtained, which can be denoted as RENum0. The overhead deducted includes but is not limited to DMRS (Demodulation Reference Signal) overhead.

[0172] In some application scenarios of the embodiments of the present application, the total number of REs occupied by non-data domain resources on the PRB allocated to the target user under a preset condition also needs to be obtained, which can be denoted as RENum PT-RS . The preset condition includes but is not limited to: under the condition of MCS init and N PRB , the configuration density of non-data domain resources is satisfied. Wherein, MCS init is the initial MCS level, and N PRB is the number of PRBs allocated to the target user.

[0173] In step 204, if the total number of REs occupied by non-data domain resources on the PRB is not 0, the actual spectral efficiency of the service channel is obtained according to a preset first formula based on the total number of REs available to the PUSCH, the total number of REs occupied by non-data domain resources on the PRB, and the initial spectral efficiency.

[0174] In some possible embodiments, the actual spectrum efficiency of the service channel can be denoted as eff', and the actual spectrum efficiency of the service channel can be calculated according to the first formula, the total number of REs available for the PUSCH, the total number of REs occupied by the non-data domain resource on the PRB, and the initial spectrum efficiency.

[0178] In some possible embodiments, there can be a spectrum efficiency offset threshold SE offset used when adjusting the MCS, obtaining the spectrum efficiency offset threshold SE offset , and summing the spectrum efficiency offset threshold SE offset and the initial spectrum efficiency eff int , and comparing the actual spectrum efficiency eff' with the summation result.

[0179] Step 206, if the actual spectrum efficiency is less than or equal to the summation result, the MCS level adjustment of the target user is ended, and the MCS level of the target user is determined as the initial MCS level.

[0180] In some application scenarios of the embodiments of the present application, if the actual spectrum efficiency is less than or equal to the summation result, i.e., eff'≤(SE offset +eff int ), the MCS level adjustment of the target user is ended, and the MCS level of the target user is the initial MCS level MCS init .

[0181] In the following, several specific scenarios are combined to illustrate how to adjust the MCS level of the target user according to the preset strategy. In order to make the description clearer, two parameters are introduced, which are the MCS level MCS0 and the spectrum power eff0 corresponding to MCS0. The description is as follows:

[0223] 4) Let the total number of REs available for PUSCH on the PRBs allocated to the UE after deducting DMRS overhead be RENum0=9504;

[0224] 5) Let MCS0, N PRB RENumPT-RS=198 under the condition that the configuration density of PT-RS resource is 1 / 3, and the total number of REs occupied by PT-RS on the PRBs allocated to the UE is determined based on the configuration density of PT-RS resource. PT-RS

[0228] 8) eff'>(eff int +SE offset ), MCS0=MCS0-1=27.5, corresponding to the spectral efficiency eff0 of 5.44335, continue to determine whether the MCS level needs to be adjusted.

[0229] 9) Let MCS0, N PRB RENumPT-RS=198 under the condition that the configuration density of PT-RS resource is 1 / 3, and the total number of REs occupied by PT-RS on the PRBs allocated to the UE is determined based on the configuration density of PT-RS resource. PT-RS

[0230] 10) Calculate the actual spectral efficiency eff' of PUSCH:

[0231]

[0232] 11) eff'<(eff int +SE offset ), the adjustment of MCS based on PT-RS resource occupation is completed.

[0233] Step 3: After the adjustment of MCS based on PT-RS resource occupation is completed, the adjusted MCS level MCS0=27.5 considering the PT-RS resource occupation is obtained.

[0234] Scenario three:

[0235] In this scenario, the target data volume is less than the data volume threshold value, and the first MCS level of the target user is greater than 1 and less than the maximum MCS level. The specific example is as follows:

[0236] ​​Step 1: The target data amount to be transmitted by the user UE to be scheduled is 190 bits, and the preset data amount threshold value is 200 bits. The target data amount is less than the data amount threshold value. The position of the MCS level adjusted based on the PT-RS resource occupation in the scheduling process is InPRBPreComp.

[0237] Step 2: The MCS level adjusted based on the PT-RS resource occupation is used when calculating the number of frequency domain resources required by the user. The specific process is as follows:

[0238] 1) Let the MCS level of the user be MCS init 5.5, and the number of PRBs allocated to the UE be 66.

[0239] a) The maximum value of the MCS level corresponding to the protocol is MCS max 28.

[0240] b) MCS 1 = 5.

[0241] c) The corresponding spectral efficiency of MCS 1 is 0.7402

[0248] 3) Let MCS0= 5.5 and eff0= 0.8086.

[0249] 4) Let the total number of REs available on the PRB allocated to the UE after deducting the DMRS overhead be

[0250] RENum0= 9504.

[0251] 5) MCS0, N PRBUnder the given conditions, based on the configuration density of PT-RS resources, the total number of REs occupied by PT-RS on the PRB allocated to this UE is RENum. PT-RS =198;

[0252] 6) Calculate the actual spectral efficiency eff of PUSCH. ′ :

[0253]

[0254] 7) Obtain the spectral efficiency offset threshold SE used when adjusting the MCS. offset =0.05.

[0255] 8) eff′ < (eff int +SE offset The process of adjusting the MCS based on PT-RS resource usage has ended.

[0256] Step 3: After the MCS adjustment process based on PT-RS resource usage is completed, the MCS level after considering PT-RS resource usage adjustment is obtained, MCS0 = 5.5.

[0257] According to the scheduling MCS level adjustment method of the embodiments of this application, the network side determines whether the MCS level needs to be adjusted based on the actual spectrum efficiency change after non-data domain resource occupancy. This can adaptively adapt to non-data domain resource density, reflect the impact of non-data domain resources on the final TBS (Transport Block Size), and improve the matching degree between scheduling spectrum efficiency and actual channel conditions. At the same time, for large packet services, the MCS level is adjusted based on non-data domain resource occupancy before authorization is issued after scheduling resource allocation is completed. The overall process reduces the computational load on the network side due to considering the adjustment of MCS level by non-data domain resource occupancy. For small packet services, the MCS level is adjusted based on non-data domain resource occupancy when calculating the number of frequency domain resources required by the user, which can achieve the goal of minimizing the segmentation of small packets.

[0258] In the third embodiment of this application, based on the above embodiments, the actual spectral efficiency may be greater than the summation result during actual execution, and this situation can be explained.

[0259] pass Figure 3 Detailed explanation, Figure 3 This is a flowchart of a method for adjusting the scheduling MCS level according to a third embodiment of this application. Optionally, it also includes steps 301-305:

[0260] Step 301: If the actual spectral efficiency is greater than the summation result, then subtract 1 from the initial MCS level to obtain the updated MCS level.

[0261] In some possible embodiments, if the actual spectral efficiency is greater than the sum result, i.e., eff ′ >(SE offset + eff int ), the initial MCS level can be reduced by 1 to obtain an updated MCS, i.e., MCS new = MCS init - 1.

[0262] At step 302, an updated spectral efficiency corresponding to the updated MCS level is obtained.

[0263] It can be understood that the updated spectral efficiency eff new corresponding to the updated MCS level can be obtained by updating the MCS level. The obtaining process of the updated spectral efficiency is similar to the obtaining process of the initial spectral efficiency corresponding to the initial MCS level at step 202, which will not be described herein again.

[0264] At step 303, the updated spectral efficiency of the service channel is obtained according to the calculation result of the first formula on the total number of REs available for the PUSCH, the total number of REs occupied by the non-data domain resource on the PRB, and the updated spectral efficiency.

[0265] In some possible embodiments, the updated spectral efficiency of the service channel can be denoted as eff′, and the updated spectral efficiency of the service channel can be calculated according to the calculation result of the first formula on the total number of REs available for the PUSCH, the total number of REs occupied by the non-data domain resource on the PRB, and the updated spectral efficiency.

[0266] The first formula can be:

[0267] wherein RENum0 represents the total number of REs available for the PUSCH, RENum PT-RS represents the total number of REs occupied by the non-data domain resource on the PRB, and eff new represents the updated spectral efficiency.

[0268] At step 304, the updated spectral efficiency is compared with the sum result.

[0269] It can be understood that, in some possible embodiments, the sum result is the sum result of the updated spectral efficiency eff new and the spectral efficiency offset threshold SE offset . The updated spectral efficiency of the service channel can be compared with the sum result.

[0270] At step 305, if the updated spectral efficiency is less than or equal to the sum result, the MCS level adjustment of the target user is ended, and the MCS level of the target user is determined as the updated MCS level.

[0271] In some application scenarios of the embodiments of the present application, if the updated spectral efficiency of the service channel is less than or equal to the sum result, i.e., eff'≤(SE offset +eff new ), the MCS level adjustment of the target user ends, and the MCS level of the target user is the updated MCS level MCS new .

[0272] According to the adjustment method of the scheduling MCS level in the embodiments of the present application, the operation steps in the case where the actual spectral efficiency is greater than the sum result are perfected, so that the method proposed in the present application is more applicable and more perfect.

[0273] In the fourth embodiment of the present application, based on the above embodiments, the MCS level adjustment of the target user can end in some cases. Optionally, the above cases include but are not limited to the following two cases:

[0274] Case one: if the initial MCS level is less than 1, the MCS level adjustment of the target user ends, and the MCS level of the target user is determined as the initial MCS level.

[0275] It can be understood that when the initial MCS is less than 1, the MCS level adjustment of the target user will not continue, and the initial MCS level is the MCS level of the target user.

[0276] The following illustrates case one in combination with several specific scenarios:

[0277] Scenario one:

[0278] In this scenario, the target data amount is greater than the data amount threshold, and the initial MCS level is less than 1. The specific example is as follows:

[0279] Step 1: the target data amount to be transmitted by the user UE to be scheduled is 50000 bits, the preset data amount threshold is 200 bits, the target data amount is greater than the data amount threshold, and the position of the MCS level adjusted based on the PT-RS resource occupation in the scheduling process is InFinalTBSComp.

[0280] Step 2: adjust the MCS level of the UE based on the PT-RS resource occupation before the scheduling resource allocation completes the issuance of the grant, and the specific process is as follows:

[0281] a) set the initial MCS level MCS init of the user to be 0.5, and the number of PRBs allocated to the UE is 20.

[0282] b) the MCS init is less than 1, and the MCS adjustment process based on the PT-RS resource occupation ends.

[0283] Step 3: After the MCS adjustment process based on PT-RS resource usage is completed, the MCS level after considering the PT-RS resource usage adjustment is 0.5.

[0284] Scene 2:

[0285] In this scenario, the target data volume is less than the data volume threshold, and the initial MCS level is less than 1. A specific example is shown below:

[0286] Step 1: The target data volume to be transmitted by the user UE to be scheduled is 96 bits. The preset data volume threshold is 200 bits. The target data volume is less than the data volume threshold. Considering the PT-RS resource occupation, the position identifier of the MCS level in the scheduling process is InPRBPreComp.

[0287] Step 2: When calculating the number of frequency domain resources required by the user, adjust the MCS level based on PT-RS resource occupancy for this UE. Specific process:

[0288] a) Assume the user's initial MCS level is MCS init The value is 0.5, and the number of PRBs allocated to this UE is 4.

[0289] b) MCS init If the value is less than 1, the MCS adjustment process based on PT-RS resource usage ends.

[0290] After the MCS adjustment process based on PT-RS resource occupancy is completed, the resulting MCS level is 0.5 after considering the PT-RS resource occupancy adjustment.

[0291] Scenario 2: If the total number of REs occupied by non-data domain resources on the PRB is 0, the MCS level adjustment of the target user is completed, and the target user's MCS level is determined as the initial MCS level.

[0292] Understandably, when the total number of REs occupied by non-data domain resources on the PRB is 0, the MCS level of the target user will not be adjusted further, and this MCS level is the target user's MCS level.

[0293] The following examples illustrate scenario two:

[0294] Scene 1:

[0295] In this scenario, the target data volume exceeds the data volume threshold, and the total number of REs used by non-data domain resources on the PRB is 0. A specific example is as follows:

[0296] Step 1: The target data amount to be transmitted by the user UE to be scheduled is 50000 bits, and the preset data amount threshold value is 200 bits. The target data amount is greater than the data amount threshold value, and the position of the MCS level adjusted based on the PT-RS resource occupation in the scheduling process is identified as InFinalTBSComp.

[0297] Step 2: The MCS level of the UE is adjusted based on the PT-RS resource occupation before the scheduling resource allocation is completed and the grant is issued. The specific process is as follows: assuming that the MCS level of the user is MCS init 5, and the number of PRBs allocated to the UE is 20. Based on the configuration density of the PT-RS resource, the total number of REs occupied by the PT-RS on the PRB allocated to the UE is RENum PT-RS = 0, and the MCS adjustment process based on the PT-RS resource occupation is completed.

[0298] Step 3: After the MCS adjustment process based on the PT-RS resource occupation is completed, the MCS level adjusted considering the PT-RS resource occupation is obtained as 5.

[0299] Scenario Two:

[0300] In this scenario, the target data amount is less than the data amount threshold value, and the total number of REs occupied by the non-data domain resource on the PRB is 0. The specific example is as follows:

[0301] Step 1: The target data amount to be transmitted by the user UE to be scheduled is 96 bits, and the preset data amount threshold value is 200 bits. The target data amount is less than the data amount threshold value, and the position of the MCS level adjusted based on the PT-RS resource occupation in the scheduling process is identified as InPRBPreComp.

[0302] Step 2: The MCS level of the UE is adjusted based on the PT-RS resource occupation when calculating the number of frequency domain resources required by the user. The specific process is as follows: assuming that the MCS level of the user is MCS init 5, and the number of PRBs allocated to the UE is 4. Based on the configuration density of the PT-RS resource, the total number of REs occupied by the PT-RS on the PRB allocated to the UE is RENum PT-RS = 0, and the MCS adjustment process based on the PT-RS resource occupation is completed.

[0303] Step 3: After the MCS adjustment process based on the PT-RS resource occupation is completed, the MCS level adjusted considering the PT-RS resource occupation is obtained as 5.

[0304] According to the method for adjusting the scheduling MCS level, the case that the MCS level adjustment of the target user can be ended is proposed, and the method considers from the actual point of view, and ends the MCS level adjustment of the target user when the initial MCS level is less than 1 and / or the total number of REs occupied by the non-data domain resource on the PRB is 0, thereby saving the computing power and time, and making the practicability of the method stronger.
