Description

Resource allocation method and device

The present application claims priority to Chinese Patent Application No. 201410018106.4, filed on Jan. 15, 2014, the entire disclosure of which is incorporated herein by reference. .

Technical field

The present application relates to the field of communications technologies, and in particular, to a resource configuration method and apparatus.

Background technique

With the evolution of mobile communication technology, the existing HSPA (High-Speed Packet Access) system and LTE (Long Term Evolution) system adopt a dynamic shared resource scheduling method, which greatly optimizes the system. The allocation of resources. At the same time, however, since each resource allocation requires a corresponding indication on the control channel, there is overhead of the control channel. For multi-user, small-volume applications (such as VoIP (Voice over Internet Protocol), etc.), the factor that restricts system capacity is no longer the system bandwidth, but the capacity of the control channel.

For a type of service such as VoIP, the size of the data packet is relatively fixed, and the time interval between the data packets also satisfies a certain regularity. To this end, SPS (Semi-Persistent Scheduling) has been introduced in 3GPP (3rd Generation Partnership Project). In semi-persistent scheduling, the resources of the system (including uplink and downlink) need only be allocated or specified once through a specially identified control channel, and then the same time-frequency resources can be periodically reused. If you need to adjust the resources used by the SPS, you need to resend the specially identified control channel for configuration. Control channels used for SPS resource allocation or reclaiming are typically identified using special RNTI (Radio Network Temporary Authentication) and/or information field bits.

In view of the characteristics of SPS, it is often used to carry VoIP-type services. The MCS (Modulation and Coding Scheme) level and resource number that are commonly used are different from those of dynamic scheduling, and are generally a subset thereof.

At present, there is no specific implementation solution for how to configure SPS resources. If the MCS level used by the SPS resource configuration does not match the actual channel, it cannot provide sufficient reference for the SPS resource configuration. Specifically, when the MCS level is higher than the MCS level that the actual channel can support, the packet error rate cannot meet the target value, and the SPS service quality cannot be guaranteed; when the MCS level is lower than the MCS level that the actual channel can support, the channel is wasted. Transmission capacity, resulting in low resource utilization.

Summary of the invention

The purpose of the application is to provide a resource configuration method and device to solve the prior art without SPS resource configuration. The problem with the implementation of the body.

The purpose of this application is achieved by the following technical solutions:

A resource configuration method, including:

Determining the frequency of dynamically scheduling data by the UE (User Equipment), the frequency is divided into frequent and sparse;

If the frequency of the dynamic scheduling data of the UE is frequent, the SPS resource configuration is performed for the UE according to the first CQI (Channel Quality Indicator) correction result; the first CQI correction result and the ACK of the dynamic scheduling initial transmission data. NACK (correct acknowledgment/error acknowledgment) information, but not related to ACK/NACK information of SPS initial data;

If the frequency of the UE dynamic scheduling data is sparse, according to the second CQI correction result, the SPS resource configuration is performed for the UE; the second CQI correction result is related to the ACK/NACK information of the SPS initial transmission data, but is related to the dynamic scheduling initial transmission. The ACK/NACK information of the data is irrelevant.

The method provided in the embodiment of the present application provides a specific SPS resource configuration implementation manner. When the dynamic scheduling data is frequent, the ACK/NACK information of the dynamically scheduled initial data participates in the CQI correction, and the ACK/NACK information of the SPS initial transmission data does not participate in the CQI correction, and the obtained correction result is referred to as the first CQI correction result, according to the first The CQI correction result is performed by SPS scheduling. When the dynamic scheduling is sparse, the second CQI correction result referenced by the SPS resource scheduling is only related to the ACK/NACK information of the SPS initial transmission data, and is independent of the ACK/NACK information of the dynamic scheduling initial transmission data, so the second CQI correction result Accurate, the selected MCS level can match the actual channel, and configure sufficient reference for SPS resources.

There are various ways to determine the frequency of the UE dynamically scheduling data. For example, according to the dynamic scheduling information and/or whether the service with dynamic scheduling bearer coexists with the service carried by the SPS, the frequency of the UE dynamically scheduling data is determined.

The dynamic scheduling information may include, but is not limited to, including the amount of dynamically scheduled buffer data of the UE, the number of dynamic scheduling of the UE in a predetermined time period, the ratio of the number of dynamic scheduling of the UE in the predetermined time period to the predetermined time period, and the like.

Based on any of the above method embodiments, preferably, the first CQI correction result and the second CQI correction result are MCS levels. Specifically, the MCS level as a result of the CQI correction may be obtained by directly correcting the MCS level, or may be performed by correcting the spectral efficiency value and using the corrected spectral efficiency value mapping.

It should be noted that the CQI correction result may also be other parameters used for SPS scheduling, which is not limited in this application.

If the first CQI correction result is the MCS level, according to the first CQI correction result, the specific implementation manner of the SPS resource configuration for the UE may be, but is not limited to, a resource table corresponding to the service carried by the SPS according to the first CQI correction result. The MCS level is selected; the SPS resource configuration is performed according to the MCS level selected from the resource table.

Preferably, the MCS is selected from the resource table corresponding to the service carried by the SPS according to the first CQI correction result. The level is implemented by: determining the first temporary MCS level according to the first CQI correction result; selecting the highest MCS level from the MCS level of the resource table not greater than the first temporary MCS level.

Preferably, the implementation manner of determining the first temporary MCS level according to the first CQI correction result may be, but is not limited to, the initial BLER (Block Error Ratio) target value and the dynamic scheduling bearer of the service carried by the SPS. If the initial BLER target value of the service is the same, the first CQI correction result is determined to be the first temporary MCS level; otherwise, the first CQI correction result is rolled back or progressive according to the difference of the initial BLER target value, First temporary MCS rating.

If the second CQI correction result is the MCS level, the specific implementation manner of the SPS resource configuration for the UE according to the second CQI correction result may be, but is not limited to, a resource table corresponding to the service carried by the SPS according to the second CQI correction result. The MCS level is selected; the SPS resource configuration is performed according to the MCS level selected from the resource table.

Preferably, according to the second CQI correction result, the implementation manner of selecting the MCS level from the resource table corresponding to the service carried by the SPS may be, but is not limited to, determining the second temporary MCS level according to the second CQI correction result; Among the MCS levels in the table that are not greater than the second temporary MCS level, the highest MCS level is selected.

Preferably, according to the second CQI correction result, the specific implementation manner of determining the second temporary MCS level may be, but is not limited to, determining that the second CQI correction result is the second temporary MCS level.

Based on the above-described arbitrary MCS level as an example of the CQI correction result (the first CQI correction result or the second CQI correction result), if the SPS resource is configured to be reconfigured, the SPS resource configuration is performed according to the MCS level selected from the resource table. And determining whether the MCS level selected from the resource table is the same as the MCS level currently used by the SPS; if the same, the SPS resource is not reconfigured; if not, the SPS resource is weighted according to the MCS level selected from the resource table. Configuration.

Based on the above-described arbitrary MCS level as an example of the CQI correction result (the first CQI correction result or the second CQI correction result), the resource table used for selecting the MCS level is determined according to the following manner: the level C limited according to the current control channel _n , the number of the resource table is determined as j=n%Ntab, where % represents the modulo operation, and Ntab is the number of resource tables included in the resource table set corresponding to the service carried by the SPS; determining the service corresponding to the SPS bearer The resource table numbered j in the resource table set is the resource table used for selecting the MCS level. The resource table number in the resource table set corresponding to the service carried by the SPS is larger, and the difference between two adjacent MCS levels in the resource table is The value is larger.

The current control channel limited level C _n is determined according to the control channel resource utilization rate. For example, according to the control channel resource utilization, the number of control channels is limited (ie, the control channel is limited) into levels C ₁ , C ₂ , . . . , C _N , where N=N _t *Ntab, n=1. The larger the value of 2, ..., N, n is, the more severe the situation is that the number of control channels is limited. The N _t is the number of values included in the value set of the SPS resource scheduling period T. It should be noted that the above is only an example of the C _n determination, and other implementation manners for determining the C _n according to the control channel resource utilization are also applicable to the present application, and details are not described herein again.

As described above, resource configuration for the SPS may be reconfiguration. There are several trigger conditions for reconfiguration, such as periodic reconfiguration. Correspondingly, the SPS resource adjustment period T=T_m may be determined according to the current control channel limited level Cn, where T_m is the mth value in the value set of the SPS resource adjustment period, m=ceil(n/ Ntab), ceil means round up.

Based on any of the foregoing method embodiments, preferably, if the frequency of the UE dynamically scheduling data is frequent, only the first CQI correction is maintained; if the frequency of the UE dynamically scheduling data is sparse, the first CQI correction and the second CQI correction are maintained. .

The maintenance CQI correction (the first CQI correction or the second CQI correction) refers to adjusting the CQI value used by the current channel according to the ACK/NACK information of the initial transmission data (if the downlink CQI correction is also performed according to the CQI reporting of the UE). It is reflected in MCS level, spectrum efficiency, code rate, SNR, etc., and saves the current adjusted CQI value for resource scheduling and as a reference for the next CQI correction.

detailed description

The technical solutions provided by the embodiments of the present application will be described below with reference to the accompanying drawings.

As shown in FIG. 1 , a resource configuration method provided by an embodiment of the present application includes:

Step 100: Determine the frequency of the UE dynamically scheduling data, and the frequency is divided into frequent and sparse.

In the embodiment of the present application, the UE refers to a UE that starts the SPS.

For the data transmitted in the form of a data packet, the frequency of the UE dynamically scheduling data may also be referred to as the frequency of the UE dynamically scheduling the data packet.

If the frequency of the UE dynamically scheduling data is frequent, step 110 is performed to perform SPS resource configuration for the UE according to the first CQI correction result.

The first CQI correction result is related to the ACK/NACK information of the dynamic scheduling initial transmission data, but is independent of the ACK/NACK information of the SPS initial transmission data.

The first CQI correction result may also be referred to as a correction result of the dynamically scheduled CQI correction. In order to avoid the impact on dynamic scheduling, the SPS scheduling data packet generally does not participate in the dynamic scheduling CQI correction process, that is, the ACK/NACK information of the dynamically scheduled initial transmission data (or the initial transmission data packet) participates in the dynamic scheduling CQI correction, and the SPS initial transmission The ACK/NACK information of the data (or the initial transmission packet) does not participate in the CQI correction of the dynamic scheduling.

The first CQI correction result is a correction result of the CQI correction from the most recent dynamic scheduling of the SPS resource configuration.

For the case where the UE dynamically schedules data frequently, since the CQI correction result according to the dynamic scheduling can provide sufficient reference for the SPS resource configuration, the selected MCS level matches the actual channel, and therefore, only the dynamic scheduling CQI correction needs to be maintained. Kind.

If the frequency of the UE dynamic scheduling data is sparse, step 120 is performed to perform SPS resource configuration for the UE according to the second CQI correction result.

The second CQI correction result is related to the ACK/NACK information of the SPS initial transmission data, but is independent of the ACK/NACK information of the dynamic scheduling initial transmission data.

The second CQI correction result may also be referred to as a correction result of the CQI correction of the SPS. The ACK/NACK information of the SPS initial transmission data (or the initial transmission data packet) participates in the CQI correction of the SPS, and the ACK/NACK information of the dynamic scheduled initial transmission data (or the initial transmission data packet) does not participate in the CQI correction of the SPS.

The second CQI correction result is a correction result of the CQI correction of the last SPS from the current SPS resource configuration.

For the case where the UE dynamically schedules data sparse, since the CQI correction result according to the dynamic scheduling cannot provide sufficient reference for the SPS resource configuration, the selected MCS level does not match the actual channel, therefore, the CQI correction of the SPS is required for the SPS resource. Configuration. Correspondingly, the two CQI corrections of the CQI correction of the SPS and the CQI correction of the dynamic scheduling are maintained, wherein the dynamically scheduled CQI correction is used for dynamic scheduling resource configuration.

The so-called CQI correction function is usually implemented on the NodeB or eNodeB side. Generally divided into uplink CQI corrections and The purpose of the downlink CQI correction is to ensure that the initial transmission (first transmission) of the uplink or downlink data packet is controlled at a predetermined target value. The basic principle is to correct the spectral efficiency value or the MCS level value corresponding to the CQI according to the ACK/NACK feedback information that is transmitted for the first time in each data block. The downlink CQI correction can also use the result reported by the terminal CQI.

Wherein, if the spectral efficiency value correction is used, the corrected spectral efficiency value needs to be mapped to the MCS level.

In the method provided by the embodiment of the present application, when the dynamic scheduling data is frequent, the ACK/NACK information of the initial transmission data is dynamically scheduled to participate in the CQI correction, and the ACK/NACK information of the SPS initial transmission data does not participate in the CQI correction, and the obtained correction result is called the first modification. A CQI correction result, SPS scheduling is performed according to the first CQI correction result. When the dynamic scheduling is sparse, the second CQI correction result referenced by the SPS resource scheduling is only related to the ACK/NACK information of the SPS initial transmission data, and is independent of the ACK/NACK information of the dynamic scheduling initial transmission data, so the second CQI correction result Accurate, the selected MCS level can match the actual channel, and configure sufficient reference for SPS resources. In the case of coexisting dynamic scheduling services (dynamic scheduling data is frequent) and less (dynamic scheduling data sparse), both SPS scheduling performance and system resource utilization can be effectively improved.

In the embodiment of the present application, the CQI correction of the SPS is the same as the CQI correction process of the dynamic scheduling, except that the CQI modification of the SPS uses the ACK/NACK information of the SPS initial transmission data. The MCS level and/or spectral efficiency value required for the correction process is the same as the MCS level and/or spectral efficiency value used in the dynamically scheduled CQI correction.

In the embodiment of the present application, various steps are implemented in various ways. The following describes the implementation of each step separately. It should be noted that the implementations exemplified in the following embodiments can be implemented in cooperation with each other to form a new embodiment.

For the step 100, a preferred implementation manner is to determine the frequency of the UE dynamically scheduling data according to the dynamic scheduling information and/or whether the service that dynamically schedules the bearer coexists with the service carried by the SPS.

For example, the frequency of the dynamic scheduling data of the UE may be determined according to the amount of the dynamically scheduled buffer data of the UE. If the amount of the dynamically scheduled buffered data exceeds the preset buffering threshold, the frequency of the dynamic scheduling data of the UE is determined to be frequent, otherwise the UE is determined. The frequency of dynamically scheduling data is sparse. The frequency of the dynamic scheduling data of the UE may be determined only according to the number of dynamic scheduling of the UE in the predetermined time period. If the number of dynamic scheduling of the UE exceeds the preset threshold in the predetermined time period, the frequency of the dynamic scheduling data of the UE is determined. To be frequent, otherwise the frequency of the UE dynamically scheduling data is determined to be sparse. The frequency of the dynamic scheduling data of the UE may be determined only according to the ratio of the number of dynamic scheduling of the UE to the predetermined time period in a predetermined time period. If the ratio exceeds a preset threshold, the dynamic scheduling data of the UE is determined. The frequency of the UE is frequent, otherwise the frequency of the UE dynamically scheduling data is determined to be sparse. The frequency of dynamically scheduling data of the UE may be determined according to whether there is a service of the dynamic scheduling bearer that coexists with the service carried by the SPS. If the service of the dynamic scheduling bearer coexists with the service carried by the SPS exists, the frequency of dynamically scheduling the data of the UE is determined. To be frequent, otherwise, the frequency of the UE dynamically scheduling data is determined to be sparse. Certainly, the frequency of the UE dynamically scheduling data may be determined according to the foregoing conditions, if the UE dynamically schedules the buffered data volume to exceed a preset buffer amount threshold, or the UE dynamically schedules within a predetermined time period, or the UE within a predetermined time period. If the ratio of the number of times of dynamic scheduling to the predetermined time period, or the service of the dynamic scheduling bearer coexisting with the service carried by the SPS, the frequency of dynamically scheduling the data of the UE is determined to be frequent; if the amount of dynamically scheduled buffer data of the UE does not exceed the preset The buffer amount threshold, the number of dynamic scheduling of the UE in the predetermined time period does not exceed the preset number of times threshold (or the ratio of the number of dynamic scheduling of the UE to the predetermined time period within a predetermined time period does not exceed a preset ratio threshold), If there is no dynamic scheduling bearer service coexisting with the service carried by the SPS, the frequency of the UE dynamically scheduling data is determined to be sparse.

In the embodiment of the present application, preferably, the first CQI correction result is an MCS level.

In the embodiment of the present application, preferably, the second CQI correction result is an MCS level.

The MCS level as a result of the CQI correction may be obtained by directly correcting the MCS level, or may be obtained by correcting the spectral efficiency value and using the corrected spectral efficiency value mapping.

If the first CQI correction result is the MCS level, the specific implementation of step 110 may be, but is not limited to, selecting an MCS level from the resource table corresponding to the service carried by the SPS according to the first CQI correction result; The MCS level is configured for SPS resources.

According to the first CQI correction result, there are various implementation manners for selecting the MCS level from the resource table corresponding to the service carried by the SPS. For example, selecting the same MCS level as the first CQI correction result from the resource table corresponding to the service carried by the SPS; or selecting the MCS level closest to the first CQI correction result from the resource table corresponding to the service carried by the SPS, and the like. . Preferably, the first temporary MCS level is determined according to the first CQI correction result; and the highest MCS level is selected from the MCS level of the resource table not greater than the first temporary MCS level.

Preferably, the implementation manner of determining the first temporary MCS level according to the first CQI correction result may be, but is not limited to, if the initial BLER target value of the service carried by the SPS is the same as the initial BLER target value of the service of the dynamically scheduled bearer. And determining that the first CQI correction result is the first temporary MCS level; otherwise, the first CQI correction result is rolled back or progressive according to the difference of the initial transmission BLER target value, to obtain the first temporary MCS level.

Specifically, according to the difference in SNR corresponding to different initial transmission LBERs, the MCS level is converted, and the backtracking or progressive is performed accordingly.

Specifically, the first CQI correction result is rolled back or progressive; the degree of retreat or progressive is based on actual conditions. Determined by the process, this application is not limited.

If the second CQI correction result is an MCS level, the specific implementation of step 120 may be, but is not limited to, selecting an MCS level from a resource table corresponding to the service carried by the SPS according to the second CQI correction result; and selecting according to the selected resource table. The MCS level performs SPS resource configuration.

According to the second CQI correction result, there are various implementation manners for selecting the MCS level from the resource table corresponding to the service carried by the SPS. For example, the MCS level with the same second CQI correction result is selected from the resource table corresponding to the service carried by the SPS; or the MCS level closest to the second CQI correction result is selected from the resource table corresponding to the service carried by the SPS. Preferably, the second temporary MCS level is determined according to the second CQI correction result; and the highest MCS level is selected from the MCS levels in the resource table that are not greater than the second temporary MCS level.

In the embodiment of the present application, the first temporary MCS level and the second temporary MCS level are both recorded as MCS_tmp.

In the embodiment of the present application, the MCS level selected from the resource table is referred to as MCS_SPS.

Based on the above-described arbitrary MCS level as an example of the CQI correction result (the first CQI correction result or the second CQI correction result), if the SPS resource is configured to be reconfigured, the SPS resource configuration is performed according to the MCS level selected from the resource table. Determining whether the MCS level selected from the resource table is the same as the MCS level currently used by the SPS; if the same, the SPS resource is not reconfigured (ie, the control channel is not sent to the UE for reconfiguration of the SPS resource); if not, The SPS resources are reconfigured according to the MCS level selected from the resource table (ie, the control channel is sent to the UE for reconfiguration of the SPS resources).

Further, if the reconfiguration of the SPS resource is required, but the control channel is unable to transmit the SPS resource reconfiguration due to congestion control, etc., the transmission may be performed in the next subframe.

There are various implementations of the resource table used to select the MCS level based on the above-described arbitrary MCS level as an example of the CQI correction result (the first CQI correction result or the second CQI correction result). For example, the resource table may be formed by all the MCS levels and resource lists corresponding to the services carried by the SPS. The resource table may also be determined from a resource table set corresponding to the service carried by the SPS.

In the embodiment of the present application, for a service carried by an SPS, a plurality of resource table extraction modes may be defined; and the resource table corresponding to all MCS levels and resource lists corresponding to the service carried by the SPS is extracted according to the defined resource table extraction manner. The resource table is obtained. Correspondingly, the resource table set includes a resource table composed of all MCS levels and resource lists corresponding to the service carried by the SPS, and a extracted resource table. For the service i carried by the SPS, the resource table formed by all corresponding MCS levels and resource lists is recorded as Tabi_1, and the corresponding resource table set can be recorded as {Tabi_1, Tabi_2, ..., Tabi_Ntab}, Tabi_j, 2≤j≤Ntab It was extracted by Tabi_1 and As the value of j increases, the resource table Tabi_j is sparse. The so-called resource table is sparse, which means that the difference between two adjacent MCS levels in the resource table is large. For simplicity, the services carried by different SPSs can be set to the same value of Ntab. For example, the MCS levels included in Tabi_1 are MCS1, MCS2, MCS3, MCS4, MCS5, MCS6, MCS7, and MCS8; the MCS levels included in Tabi_2 are MCS1, MCS3, MCS5, and MCS7, respectively; and the MCS levels included in Tabi_3 are respectively MCS1, MCS4, MCS7.

Preferably, the resource table used for selecting the MCS level is determined according to the following method: determining the number of the resource table j=n%Ntab according to the current control channel restricted level C _n , wherein % represents the modulo operation, Ntab a number of resource tables included in the resource table set corresponding to the service carried by the SPS; determining a resource table numbered j in the resource table set corresponding to the service carried by the SPS as a resource table used for selecting an MCS level, The larger the resource table number in the resource table set corresponding to the service carried by the SPS, the larger the difference between the two adjacent MCS levels in the resource table.

In the embodiment of the present application, the combination of T and Tabi_j may be semi-statically set according to the control channel resource utilization rate and different stages of network construction. The larger the T, the longer the judgment period for SPS scheduling, the fewer the number of SPS scheduling and the transmission of the control channel; the more sparse Tabi_j, the SPS scheduling judgment, the SPS resources are unchanged (that is, no reconfiguration is required) The higher the probability, the lower the probability of transmitting the control channel for SPS scheduling, and the less control channel required. Therefore, the larger T is, or the more sparse Tabi_j is, the less the number of control channels the system requires and the higher the degree of control channel savings. The control channel resource utilization rate may be defined as the ratio of the actual used control channel resources to the total control channel resources. The higher the ratio, the worse the control channel performance. When the threshold is higher than a certain threshold, the performance of the control channel cannot be guaranteed. Will seriously affect the communication quality of the system.

According to the control channel resource utilization, different SPS resource adjustment period T and SPS scheduling resource table combinations are selected, and the control channel is saved with moderate throughput efficiency, thereby improving the overall resource utilization of the system.

If the SPS resource reconfiguration is performed periodically, it is preferable to determine whether the UE reaches the next resource adjustment period before determining the frequency of the UE dynamically scheduling data. Specifically, it can be implemented by a timer.

The technical solution provided by the embodiment of the present application is described in detail below by taking the configuration of the SPS resource by the eNodeB in the LTE system as an example.

The SPS resource adjustment period T (the unit can be in milliseconds) is set in the eNodeB, and the resource scheduled by the SPS needs to be reconfigured every T milliseconds. The value of T can be configured, and the value set is set to {T_1, T_2,... , T_Nt}, where Nt is the number of elements in the set of values of T, and the value numbers in the set are in the order of decreasing values.

The SPS resource table used by different services is also pre-stored in the eNodeB, and the SPS resource table gives a list of available MCS levels and resources. Each service can define multiple SPS resource table extraction methods. For example, for service i, you can define its corresponding table set, which is recorded as {Tabi_1, Tabi_2,..., Tabi_Ntab}. The definition of the table set is as above, and will not be described here. .

It is assumed that in the LTE system, the UE only uses a VoIP Adaptive Multi Rate (AMR) 12.2 kbps single service, and the SPS is enabled to carry the service.

The parameter configuration is as follows:

It is assumed that the SPS resource adjustment period set by the system (core network system or eNodeB) is T=100 ms, and the SPS resource adjustment period is set in the eNodeB.

For the VoIP AMR 12.2 kbps service, according to its service type characteristics, the system can preset the full resource table that can be used for its SPS as Tab1_1, as follows:

The resource table set corresponding to the VoIP AMR 12.2 kbps service is {Tab1_1, Tab1_2, Tab1_3}, where Tab1_2 extracts MCS0/2/4/6/8/12 in Tab1_1, and Tab1_3 extracts MCS0/4/8/12 in Tab1_1.

Assume that the system configuration uses Tab1_2 in its corresponding resource table set for the VoIP AMR 12.2 kbps service. For the specific configuration, refer to the implementation manner of the foregoing embodiment, and details are not described herein again.

Based on the foregoing parameter configuration, the implementation manner of performing downlink SPS resource configuration on the UE is as shown in FIG. 2, and the uplink process is the same.

Step 200: The eNode determines that the service that is not dynamically scheduled by the UE and the service that is carried by the SPS is coexisting, and only the service of the VoIP 12.2 kps is determined to be sparse, and step 210 is performed.

In this case, the eNodeB maintains two sets of independent CQI corrections: dynamically scheduled CQI corrections and SPS CQI corrections.

The dynamically scheduled CQI correction uses the ACK/NACK information of the dynamically scheduled initial data and the CQI reported by the UE to perform CQI correction, and the initial BLER target value is 10%.

The CQI correction of the SPS uses the ACK/NACK of the initial transmission data scheduled by the SPS and the CQI corrected by the UE to perform CQI correction, and the initial BLER target value is 1%.

The SPQ CQI correction uses exactly the same algorithms and steps as the dynamic scheduling, except that the ACK and NACK used are derived from the SPS initial transmission packet, and the MCS level and/or spectral efficiency value and dynamic scheduling used in the correction process. The MCS level and/or the spectrum efficiency source are the same, and the MCS level is not adjusted for SPS scheduling.

Step 210: The eNodeB determines the MCS level obtained by correcting the CQI of the SPS as MCS_tmp, and performs step 220.

Step 220: Select the highest MCS level from the MCS level of the above-mentioned Tab1_2 that is not greater than the MCS_tmp, and record it as MCS_SPS, and perform step 230.

Step 230: Determine whether the MCS_SPS is the same as the currently used MCS level. If the same, do not send the control channel to perform SPS resource reconfiguration, go to step 250. Otherwise, go to step 240.

It should be noted that this step is skipped if there is no MCS level currently in use.

Step 240: Send a control channel, perform SPS resource reconfiguration on the UE according to the MCS-SPS, and perform step 250.

Step 250: The eNodeB determines whether the next SPS resource adjustment period is reached, and if yes, returns to step 200, otherwise continues to wait.

An example of the downlink CQI correction for SPS is as follows:

Set the parameter V _add to the spectral efficiency increment of the xth data packet relative to the x- _1th data packet; the parameter V _{add_sum_period} is the accumulated adjusted spectral efficiency value in one CQI period; the parameter V _{add_sum} is the cumulative adjustment after each CQI is reported. Spectrum efficiency value; set MCS_eff _out (y) to the output spectral efficiency value after CQI correction in the yth scheduling interval; set K as the adjustment step ratio of NACK and ACK, determined by the BLER of the initial transmission; set step to one The spectrum efficiency adjustment step size corresponding to the ACK information.

Assuming that the initial BLER target value is 10%, then K = (1-10%)/10% = 9. Set step=0.02.

The initialization parameter V _add =0, V _{add_sum_period} =0.

When the eNodeB receives a data block x ACK / NACK information, the time is calculated adjustment value V _add spectral efficiency and a total CQI reporting value _V add_sum_period adjust the spectral efficiency in the cycle, and also calculates the value of spectral efficiency after correction:

Assume that there is a broadband/subband at time k ₀

Reported, the correction process at this time is as follows:

The spectral efficiency value MCS_eff _in (k ₀ ) at this time is obtained according to the CQI value reported by the UE.

The correspondence between the CQI value and the spectrum efficiency can be found in Table 7.2.3-1 of the 3GPP TS36.213 protocol.

Calculate the V _{add_sum} at this time and the adjusted spectral efficiency output MCS_eff _out (k ₀ ):

V _{add_sum} =V _{add_sum} +V _{add_sum_period} ;

V _{add_sum_period} =0;

MCS_eff _out (k ₀ )=MCS_eff _in (k ₀ )+V _{add_sum} ;

According to the relationship between the spectrum efficiency value and the MCS level, the maximum MCS level whose spectrum efficiency value is less than or equal to MCS_eff _out (y) (or MCS_eff _out (k ₀ )) is found from MCS0 to 28, that is, the MCS level MCS_tmp of the CQI correction output.

Scene two

It is assumed that in the LTE system, the UE uses the VoIP AMR 12.2 kbps service carried by the SPS and the 384 kbps data service of the concurrent dynamic scheduling.

The parameter configuration is as follows:

It is assumed that the SPS resource adjustment period set by the system (core network system or eNodeB) is T=500 ms, and the SPS resource adjustment period is set in the eNodeB.

Assume that the system configuration uses Tab1_1 in its corresponding table subset for the VoIP AMR 12.2 kbps service (see Table 1 in the scenario 1 embodiment).

The initial BLER target for VoIP AMR 12.2 kbps service is 1%, and the initial BLER target for dynamic scheduling is 10%.

Based on the foregoing parameter configuration, the implementation manner of performing uplink SPS resource configuration on the UE is as shown in FIG. 3, and the downlink process is performed. Same as this.

Step 300: The eNodeB determines that the U has a concurrent dynamic scheduling bearer service, and determines that the frequency of the dynamic scheduling data is frequent. Step 310 is performed.

In this case, the eNodeB only maintains dynamically scheduled CQI corrections.

Step 310: The eNodeB determines the MCS_tmp by referring to the MCS level obtained by dynamically scheduling the CQI correction, and performs step 320.

Since the initial BLER target of the VoIP AMR 12.2 kbps service is 1%, which is better than the dynamic scheduling initial 10% BLER target, the dynamic scheduling CQI correction result cannot be directly used. According to the relationship between the two different initial BLER target values, The MCS obtained by dynamically scheduling the CQI correction is rolled back by one level to obtain MCS_tmp.

Step 320: Select the highest MCS level from the MCS level of the SPS resource table Tab1_1 corresponding to the VoIP AMR 12.2 kbps that is not greater than the MCS_tmp, and record it as MCS_SPS, and perform step 330.

In step 330, it is determined whether the MCS_SPS is the same as the currently used MCS level. If the same, the control channel is not sent to perform SPS resource reconfiguration, step 350 is performed; otherwise, step 340 is performed.

Step 340: Send a control channel, perform SPS resource reconfiguration on the UE according to the MCS-SPS, and perform step 350.

Step 350: The eNodeB determines whether the next SPS resource adjustment period is reached, and if yes, returns to step 300, otherwise continues to wait.
