Description

Background
With the wide application of LTE in various industries, especially the application of portable and movable eNB devices, unpredictability exists for the surrounding wireless environment, the wireless environment changes faster, and there is a larger random interference.

Common uplink resource allocation methods include frequency selective scheduling and frequency hopping, which are briefly introduced below:
frequency selection and scheduling: frequency selective scheduling can be performed by referring to a measurement Reference Signal (SRS) measurement result of a terminal, but under the scene that the wireless environment changes continuously, the frequency selection yield is not obvious, especially for the transmission of Msg5 data in the access process, no measurement report data related to the terminal can be used as a Reference, and for the Msg5 data transmission, the frequency selection algorithm has little effect.
A frequency hopping mode: interference randomization can be performed, but the algorithm complexity is higher, and the method is more suitable for scheduling of semi-persistent scheduling (SPS) services; for dynamic scheduling, since the dynamic scheduling authorizes every time, the position of the allocated resource is not fixed, and random allocation is already performed; for the eNB device that moves continuously, the current interference situation is not considered by the fixed frequency hopping position, and therefore, the advantage of frequency hopping is not obvious.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.
The method comprises the steps of firstly calculating an uplink continuous PRB resource interference coefficient based on a RIP measurement result, and then combining the uplink continuous PRB resource interference coefficient to carry out PUSCH resource allocation. According to the technical scheme, targeted allocation is achieved for each authorized position, and unallocated uplink continuous PRB resources with minimum interference are allocated in the uplink scheduling process, so that the influence of random interference on PUSCH data transmission is reduced.
Referring to fig. 1, the overall process of the resource allocation method based on RIP measurement results according to the present application is described in detail, where the process includes the following steps:
step 101: and calculating the interference coefficient of each PRB based on the RIP measurement result.
In this step, the interference coefficient of each PRB is initialized based on the RIP measurement result. Specifically, the Medium Access Control (MAC) layer converts the obtained RIP level value of each PRB into an interference coefficient corresponding to the actual power value (dBm), thereby obtaining an interference coefficient corresponding to each PRB.
Preferably, the present application sets three interference coefficients: BAD _ PRB, OK _ PRB and GOOD _ PRB respectively correspond to three interference degrees: severe interference, general interference and no interference, and the three interference coefficients satisfy the following conditions:
BAD_PRB>(OK_PRB+MaxPrbIndex),
and OK _ PRB > (GOOD _ PRB + MaxPrbIndex);
wherein MaxPrbIndex is the maximum PRB Index, that is: 99.
a preferred implementation is:
if the RIP actual power value > -90dBm, assigning the interference coefficient of the corresponding PRB to be 300, which represents serious interference;
if-110 dBm < -RIP actual power value < -90dBm, assigning the interference coefficient of the corresponding PRB to be 200, which represents general interference;
and if the actual RIP power value is < -110dBm, assigning the interference coefficient of the corresponding PRB to be 100, which represents no interference.
The above conversion needs to take into account the following factors:
(a) the RIP level value is converted into an actual power value, and a certain calculation amount exists.
Therefore, in practical applications, in order to reduce the amount of computation for converting the level value into the actual power value, the level values corresponding to the actual power values in the respective ranges may be calculated in advance, and the level values may be directly used for range matching to obtain the interference coefficient corresponding to the PRB. For example: actual power-90 dBm corresponds to a level value of 300000; actual power-110 dBm corresponds to a level value of 3000, and so on.
(b) The problem that a large number change covers a small number change is caused by directly using the level value as a calculation basis; the larger the RIP level value, the smaller the change in the actual power value, as shown in the following table:
Figure BDA0001843039770000061
step 102: and calculating the interference coefficient of the continuous PRB resource according to the interference coefficient of each PRB to obtain the corresponding interference coefficient of the uplink continuous PRB resource.
And the interference coefficient of the continuous PRB resource is the accumulation of the interference coefficients of a plurality of unallocated continuous PRBs and the corresponding PRBIndex.
When the interference coefficient of the continuous PRB resources is calculated, the corresponding PRB indexes are accumulated, so that the PRB resources meeting the conditions can be distributed sequentially from front to back in the subsequent processing.
Step 103: and carrying out PUSCH resource allocation according to the uplink continuous PRB resource interference coefficient.
And at the uplink scheduling time, calculating the interference coefficient of the continuous PRB resources by using the interference coefficient of each PRB, selecting the unallocated uplink continuous PRB resources which have the smallest interference coefficient and meet the transmission requirement from the front to the back, and performing PUSCH resource allocation as the resources scheduled at this time.
By adopting the method provided by the application to allocate the uplink resources, the interference coefficient of the continuous PRB can be ensured to accurately reflect the comparison of the interference situation no matter where the PRB is located.
Referring to fig. 2, a resource allocation process based on RIP measurement results according to the present application will be described, where the process includes the following steps:
and step 1, starting.
Step 2, at the scheduling time of each uplink PUSCH resource, classifying the RIP measurement results of each current PRB, and initializing the uplink power classes of each PRB:
(1) if Prb [ i ] _ RIP > -90dBm, the value calculterp [ i ] ═ 300, representing BAD _ Prb, i.e.: the RIP interference condition of the PRB is poor;
(2) if-110 dBm < ═ Prb [ i ] _ RIP < -90dBm, then the value calculated RIP [ i ] _ 200 is assigned, which represents OK _ Prb, i.e.: RIP interference condition of the PRB is moderate;
(3) if Prb [ i ] _ RIP < -110dBm, then the value calculated RIP [ i ] ═ 100, representing GOOD _ Prb, i.e.: the RIP interference condition of the PRB is good;
wherein, Prb [ i ] _ RIP represents the RIP actual power value of ith Prb, and the range of i is [0,99 ].
As described above, in order to reduce the amount of calculation for converting the level value into the actual power value, in practical use, the level values corresponding to the actual power values in the respective ranges are calculated in advance, and the level values are directly used for range matching, thereby obtaining the interference coefficient corresponding to the PRB. For example:
actual power-90 dBm corresponds to a level value of 300000;
the actual power-110 dBm corresponds to a level value of 3000.
Step 3, initializing relevant parameters of the continuous PRB information to be distributed, specifically comprising the following steps:
initializing an interference coefficient AllocPrbAllInfer of continuous PRB information to be distributed to a maximum value of 0 xFFFFFFFF;
three parameters AllocPrbNum, AllocPrbStartIdx, allocprbenddx are initialized to 0.
The four parameters are used for recording the condition of the current continuous PRB resources to be allocated; after the resource allocation process is finished, the information recorded by the four parameters is the continuous PRB resource which meets the transmission requirement as far as possible and has the minimum interference coefficient.
And 4, initializing a cycle i: i ═ bandwidth PUSCH initial PRB Index, i.e.: i ═ Bandwidth _ startpbidx.
Step 5, judging whether i reaches the PRB Index of the end of the bandwidth PUSCH;
if yes, go to step 18 and end.
If not, go to the next step.
Step 6, judging whether the Prb [ i ] is distributed or not;
if yes, entering step 12 and continuing to circulate;
if not, go to the next step.
Step 7, initializing continuous PRB information with Prb [ i ] as a starting position:
(1) starting PRB index of continuous PRB block: PrbStartIdx ═ i;
(2) end of consecutive PRB block PRB index: PrbEndIdx ═ i;
(3) calculating the interference coefficient of the continuous PRB block with Prb [ i ] as the starting position: prballnfer ═ calcalaterip [ i ] + i;
(4) the PRB number of the continuous PRB block taking Prb [ i ] as the starting position: PrbNum ═ 1.
And 8, judging whether the continuous PRB information to be distributed needs to be updated or not.
The judgment conditions in the step are as follows:
the number AllocPrbNum of PRBs to be distributed is equal to the number PrbNum of continuous PRBs taking Prb [ i ] as the starting position,
and the interference coefficient PrbAllInfer < (interference coefficient AllocPrbAllInfer) of the continuous PRB block taking the Prb [ i ] as the starting position is the interference coefficient AllocPrbAllInfer of the PRB block to be distributed;
if the condition is met, entering the next step to update the continuous PRB information to be distributed;
if the condition is not satisfied, step 10 is entered directly.
And 9, updating the information of the continuous PRB to be distributed:
AllocPrbStartIdx=PrbStartIdx;
AllocPrbEndIdx=PrbEndIdx;
AllocPrbAllInfer=PrbAllInfer;
AllocPrbNum=PrbNum。
and step 10, taking the Prb [ i ] as a starting position, traversing a plurality of PRBs requested to be allocated by the user backwards, wherein the initial j is i + 1.
Step 11, judging j > (i + UsreqRuNum), wherein the UsreqRuNum is the number of PRBs requested to be allocated by a user, the parameter is one input of the algorithm, and the number of the PRBs meeting the data requirement to be transmitted by the terminal is calculated according to the terminal BSR and the like;
however, this calculation does not belong to the method described in the present application;
if yes, entering step 12, and continuing to cycle and traverse;
if not, the step 13 is entered.
And step 12.i + +, returning to the step 5.
Step 13, judging whether Prb [ j ] is distributed or not:
if yes, entering the step 17;
if not, entering the next step;
step 14, updating continuous PRB information with Prb [ i ] as a starting position:
(1) end positions of consecutive Prb blocks with Prb [ i ] as starting position: PrbEndIdx is j;
(2) interference coefficient of consecutive Prb blocks starting from Prb [ i ]: prballnfer + (calcalaterip [ j ] + j;
(3) the PRB number of the continuous PRB block taking Prb [ i ] as the starting position: PrbNum + +.
And step 15, comparing the continuous PRB block taking the Prb [ i ] as the starting position with the currently recorded PRB block to be allocated, and updating the continuous PRB block to be allocated into a continuous block with the minimum interference coefficient on the basis of meeting the requirement of allocating the number of PRBs by a user as much as possible.
The method comprises the following three conditions:
condition (1) determines whether the following conditions are satisfied: the number of PRBs requested to be allocated by a user, UsreqRuNum, is equal to the number of continuous PRBs PrbNum taking Prb [ i ] as an initial position, the number of PRBs requested to be allocated by the user, UsreqRuNum, is equal to the currently recorded number of continuous PRBs to be allocated, AllocPrbNum, and the currently recorded interference coefficient of continuous PRBs to be allocated, AllocPrbAllInfer, is equal to the interference coefficient of continuous PRB blocks taking Prb [ i ] as an initial position, PrbAllInfer;
if not, continuously judging whether the condition (2) is met;
if yes, entering the next step;
the condition (2) judges whether or not the following conditions are satisfied: usrreqrorqnum > AllocPrbNum & & AllocPrbNum < PrbNum;
if not, continuously judging whether the condition (3) is met;
if yes, entering the next step;
the condition (3) judges whether or not the following conditions are satisfied: UsreqRuNum > AllocPrbNum
&&AllocPrbNum==PrbNum
&&AllocPrbAllInfer>=PrbAllInfer;
If not, go to step 17;
if so, go to the next step.
Step 16, updating the information of the continuous PRB to be distributed:

AllocPrbEndIdx=PrbEndIdx;
AllocPrbAllInfer=PrbAllInfer;
AllocPrbNum=PrbNum。
step 17, j + +, return to step 11, continue circulating j;
and step 18, ending. The recorded information of the continuous PRBs to be allocated is as follows: AllocPrbNum, allocprballlnfer, AllocPrbStartIdx, allocprbenddx, which correspond to assignable contiguous PRB blocks that meet the user data transmission requirements as much as possible and have the smallest interference coefficients.
