It is more than terminal in the target time slot in order to avoid the quantity for the PDCCH candidate that base station is configured in target time slot On PDCCH maximum detect number, so as to caused terminal increase PDCCH detect number, the embodiment of the invention provides A kind of detection method of Physical Downlink Control Channel, sending method and equipment, in the method for the embodiment of the present invention, terminal and base It is quasi- to pass through default discarding rule, part PDCCH candidate is abandoned, thus the PDCCH candidate that terminal just no longer goes detection to be dropped, Base station will not dispatch the terminal on the PDCCH candidate that these are dropped simultaneously, by handling above, energy of the embodiment of the present invention Enough reduce the number of terminal detection PDCCH.

Referring to Fig. 1, the embodiment of the invention provides a kind of detection methods of Physical Downlink Control Channel, are applied to terminal, The detection method includes:

Step 11, when the first quantity is more than the second quantity, determine that the PDCCH of detection required in target time slot is candidate, First quantity is the quantity of the candidate required detection number of whole PDCCH configured in the target time slot, described Second quantity is the quantity of maximum detection number of the terminal in the target time slot；

Here, the first quantity is in time slot that the network equipment is configured by terminal, to carry out detection institute to whole PDCCH candidates The number needed, that is, to the sum of the number that is detected of each PDCCH candidate that each search space is concentrated, for example, this when It include the first search space collection and the second search space collection in gap, it includes 28 PDCCH candidates that the first search space, which is concentrated, and every A PDCCH candidate needs to detect 1 time, and it includes 10 PDCCH candidates that the second search space, which is concentrated, and each PDCCH candidate needs Detection 2 times, then the candidate required detection number of whole PDCCH of the time slot is 48 times；Second quantity is according to as defined in agreement The maximum detection number that terminal is able to carry out on the time slot, such as the time slot is the time slot that subcarrier spacing is 15KHz, then According to the agreement regulation in upper table, the maximum detection number that terminal can be carried out on the time slot is 44 times.

The maximum detection number that can detecte on a serving cell in a slot s lot with an above UE Mapping table be illustrated.On the time slot that subcarrier spacing is 15KHz, the maximum detection that terminal can be carried out is secondary Number is 44 times, if the candidate required detection number of whole PDCCH that base station is configured on the time slot by terminal has been more than 44 times, The whole PDCCH candidates for example, configured to base station carry out detection and need 48 times, and wherein terminal can be sent according to base station The PDCCH that is configured for itself of configuration information gain of parameter base station is candidate and its described search space collection and search space Included Downlink Control Information in collection, terminal can be calculated according to the Downlink Control Information of search space collection and be learnt to the search The number that whole PDCCH candidates in the collection of space are detected, and then the detection number of each search space collection is summed to obtain The quantity of required detection number candidate to the whole PDCCH configured in the time slot, that is, the first quantity.

In base station the detection number of the first quantity of configuration be more than oneself the second quantity for can be carried out in the time slot most In the case where big detection number, terminal can be detected preferentially in public search space (common search space, CSS) PDCCH is candidate, then detects the specific search space of terminal again according to the difference of maximum detection number and CSS PDCCH detection number PDCCH in (UE-specific search space, USS) is candidate.In this case, it is possible to since base station is in terminal institute PDCCH is had sent on PDCCH candidate except the maximum times that can be detected, can not detect PDCCH so as to cause terminal, thus Increase the number of terminal detection PDCCH.It should be noted that due to terminal be blind examination is carried out on PDCCH candidate, so, It is that the candidate required detection number of whole PDCCH that terminal configures on a time slot is greater than terminal in the target time slot in base station On maximum detection number when, terminal may also detect PDCCH by blind examination in maximum detection number, only exist in base station In the case where having sent PDCCH on PDCCH candidate except the maximum detection number that terminal can be detected, terminal has carried out second When also failing to detect PDCCH after the detection of the maximum detection number of quantity, terminal is increased to the detection number of PDCCH.

In order to avoid the generation of above situation, the embodiment of the present invention passes through the PDCCH that is configured in the network equipment by terminal The PDCCH for determining that part actual needs is detected in candidate is candidate, so that detecting to part actual needs The sum of the detection number of PDCCH candidate no more than the maximum detection number that terminal can be carried out on the time slot.

Step 12, PDCCH is detected on the PDCCH candidate of the required detection.

Here it is possible to understand, base station sends PDCCH on the PDCCH candidate of part also based on identical rule, due to Terminal and benchmark are based on identical rule, so for institute determined by the PDCCH candidate of transmission and terminal determined by benchmark The PDCCH candidate that need to be detected be it is identical, terminal only on the PDCCH candidate of the required detection detects PDCCH, so as to subtract Detection number of few terminal to PDCCH candidate.

The candidate required detection number of whole PDCCH that the embodiment of the present invention is configured in target time slot, is more than terminal In the maximum detection number in the target time slot, determine that the PDCCH detected is candidate so as to the needs into Maximum detection number of the sum of the PDCCH of the row detection candidate detection number no more than terminal on the time slot, terminal is only at this Detect PDCCH on the PDCCH candidate detected, at the same base station also on the PDCCH candidate detected to Terminal sends PDCCH, so that terminal can reduce the detection number of PDCCH.

For in step 11, determine that the step of the PDCCH candidate of detection required in target time slot may include:

According to second quantity and first quantity, the detection number for needing the third quantity abandoned is determined；

Here, continue to be illustrated with the example above.In order to avoid the generation of the situation in the example above, according to agreement pair The regulation of the maximum detection number of each time slot and each serving cell, terminal can determine is in subcarrier spacing certainly The maximum times that can be detected on the time slot of 15KHz are 44 times, if base station is on the time slot for the PDCCH candidate's of terminal configuration Maximum detection number is 48 times, then terminal can be determined according to the difference of the two needs to abandon 4 detection numbers.

It should be noted that being preferably the difference of the first quantity Yu the second quantity for third quantity, said with the example above Bright is 48 and 44 difference, that is, preferably abandons 4 detection numbers.But it is understood that the quantity of discarding 4 times can be greater than, i.e. the third quantity difference that is greater than or equal to the first quantity and the second quantity, and less than the first quantity.

According to default discarding rule, is selected from the target time slot and needs the PDCCH of the 4th quantity abandoned candidate, And determine that the remaining PDCCH in the target time slot is candidate, wherein the detection number of the PDCCH candidate to the 4th quantity More than or equal to the third quantity；

Here, continue to be illustrated with the example above.Need to abandon 4 detection numbers in the example above, so that Base station is in target time slot by the detection number of terminal configuration no more than the maximum detection time that terminal can be carried out on the time slot Number, in embodiments of the present invention, by the default rule that abandons by part PDCCH candidate discarding, to reduce maximum required inspection Number is surveyed, such as 2 PDCCH candidates that the first search space in target time slot is concentrated abandon, wherein the first search space collection Downlink Control Information be the second Downlink Control Information for dispatching data, and 2 kinds of formats included in the Downlink Control Information Downlink Control Information size of data it is different, the PDCCH candidate of the search space collection is needed to be detected twice, therefore at this The maximum detection number that search space concentrates 2 PDCCH candidates of discarding that terminal may make to can be carried out on the time slot is not small In the candidate required maximum detection number of PDCCH that base station is configured.According to upper table it is found that different sub-carrier interval when In gap, the maximum detection number that terminal can be carried out is different.

The remaining PDCCH is candidate, and the PDCCH for being determined as the required detection in the target time slot is candidate.

Here, in PDCCH candidate base station configured, the PDCCH for removing discarding is candidate, and remaining PDCCH is candidate, really The PDCCH for being set to the required detection in the target time slot is candidate.

The candidate required whole detection numbers of the PDCCH that the embodiment of the present invention is configured in target time slot, are more than terminal In the maximum detection number in the target time slot, rule is abandoned by default, it is candidate to abandon part PDCCH, so as to surplus Maximum detection number of the remaining PDCCH candidate detection number no more than terminal on the time slot, terminal no longer go detection to be lost The PDCCH of abandoning is candidate, while base station will not dispatch the terminal on the PDCCH candidate that these are dropped, so that terminal can Reduce the detection number of PDCCH.

Further, the default discarding rule can be the rule based on design variables, and the design variables include mesh At least one in the index of search space collection, the index of CCE, polymerization grade and the 4th quantity configured on mark time slot Person.Which can be determined according to the discarding rule or function of the discarding PDCCH candidate of this four variable-definitions in search space collection Which polymerization grade on abandon the position of the PDCCH candidate which PDCCH is candidate, and abandons.

Further, in the default discarding rule, the discarding quantity in the PDCCH candidate of higher polymerization grade does not surpass The discarding quantity in the PDCCH candidate of lower polymerization grade is crossed, alternatively, the discarding ratio in the PDCCH candidate of higher polymerization grade Example, no more than the discarding ratio in the PDCCH candidate of lower polymerization grade.

Here, since the quantity of the PDCCH candidate of higher polymerization grade is often less, and the PDCCH of lower polymerization grade Candidate quantity is relatively more, and by the default discarding rule, the lower PDCCH of discarding polymerization grade that can be more is candidate, The influence to the PDCCH candidate of higher polymerization grade is reduced, the collision probability between different user terminals is reduced.

It is described according to default discarding rule among the above, it is selected from the target time slot described in needs abandon The step of the PDCCH candidate of 4th quantity may include:

According to the first preset rules, determine that the PDCCH for needing to abandon in each polymerization grade of each search space collection is waited 5th quantity of choosing, wherein the described 5th of the PDCCH candidate for needing to abandon in each polymerization grade of each search space collection Quantity and value, be equal to the 4th quantity, and to the PDCCH for needing to abandon in each polymerization grade of each search space collection The sum of candidate detection number is greater than or equal to the third quantity；

And according to the second preset rules, from each polymerization grade of each search space collection in PDCCH candidate, choosing The PDCCH for selecting out the 4th quantity is candidate.

In embodiments of the present invention, PDCCH candidate will be abandoned and be divided into two levels, the first level is i.e. according to the first default rule Then, it determines and abandons several PDCCH candidate collections of which polymerization grade in which search space collection, the second level is i.e. according to the Two preset rules abandon the position of which or that several PDCCH candidate collection in the candidate collection of multiple same polymeric grades. It is further detailed below by citing.Such as currently need to abandon 6 detection numbers, have at this time polymerization grade be 2,4, 8 PDCCH is candidate, and these candidates are distributed in the first search space collection and the second search space is concentrated, and need pre- according to first If regular, the quantity for the PDCCH candidate for needing to abandon in each polymerization grade of each search space collection is determined, such as according to One preset rules, which determine to concentrate in the first search space, abandons the PDCCH candidate that 2 polymerization grades are 2, and according to the first search The Downlink Control Information of space collection determines that the every PDCCH candidate concentrated to the search space needs to carry out 2 detections, then may be used It determines and concentrates 2 PDCCH candidates of discarding that can abandon 4 detection numbers in the first search space, concentrated in the second search space It abandons the PDCCH candidate that 1 polymerization grade is 2 and the PDCCH that 1 polymerization grade is 4 is candidate, and according to the second search space collection Downlink Control Information determine to the search space concentrate every PDCCH candidate need to carry out 1 time detection, then searched second Rope space collection abandons 2 again can meet the target that need to abandon 6 detection numbers altogether；It needs further exist for according to the second preset rules The position that the PDCCH candidate abandoned needed for determining concentrates in affiliated search space, such as the PDCCH that 2 polymerization grades are 2 are waited It is selected in the position of the first search space concentration, such as is concentrated with the PDCCH candidate that 4 polymerization grades are 2 in the first search space, Position of the 2 PDCCH candidates that demand abandons needed for determining in 4, such as first be arranged in order and third.

Wherein, it includes: for fall-back transmission or scheduling data that configured Downlink Control Information is concentrated in each search space The first Downlink Control Information or the second Downlink Control Information for dispatching data；

The wherein size of data and the second format of the first format Downlink Control Information in first Downlink Control Information Each of the size of data of Downlink Control Information is identical, the search space for including first Downlink Control Information is concentrated The detection number of PDCCH candidate is 1 time；

Under the size of data and the 4th format of the third format Downlink Control Information in second Downlink Control Information Each of when the size of data of row control information is identical, the search space for including second Downlink Control Information is concentrated The detection number of PDCCH candidate is 1 time；Each of otherwise, the search space for including second Downlink Control Information is concentrated The detection number of PDCCH candidate is 2 times.

Here, the first Downlink Control Information can be fallback DCI (DCI format 0_0 and DCI format1_ 0), wherein the size of data and the second format Downlink Control Information DCI of the first format Downlink Control Information DCI format 0_0 The size of data of format 1_0 is identical, so each PDCCH that the search space for including the first Downlink Control Information is concentrated Candidate terminal needs to detect 1 time；Second Downlink Control Information can be DCI (DCI the format 0_1 and DCI of scheduling data Format 1_1), the wherein size of data of third format Downlink Control Information DCI format 0_1 and the 4th format downlink control When the size of data of information DCI format 1_1 processed is identical, the search space for including the second Downlink Control Information is concentrated every A PDCCH candidate terminal needs to detect 1 time, otherwise, when the data of third format Downlink Control Information DCI format 0_1 are big When small different with the size of data of the 4th format Downlink Control Information DCI format 1_1, to including the second Downlink Control Information Search space concentrate each PDCCH candidate terminal need to detect 2 times.

In order to better illustrate the first preset rules, the present invention provides three preferred embodiments, wrapped in each embodiment Include one first preset rules.It is understood that specific rule can be defined according to four variables among the above, it is unlimited In four following embodiments.

First, the 5th of the PDCCH candidate for needing to abandon in each polymerization grade of each search space collection of determination the The step of quantity may include:

According to the sequence that polymerization grade is incremented by, the PDCCH that needs to abandon in each polymerization grade candidate the is determined one by one Six quantity, until need the sum of the detection number of PDCCH candidate abandoned to reach the third quantity to fixed, described the In the quantity for the PDCCH candidate that six quantity abandon for the quantity of PDCCH candidate and the needs of current residual of the polymerization grade Smaller；Wherein, if the PDCCH candidate for needing to abandon in a polymerization grade is more than or equal to 2, and the polymerization grade PDCCH candidate is distributed at least two search spaces concentration, then the sequence incremental according to the index of search space collection, by the polymerization The PDCCH candidate for needing to abandon in grade divides equally to be concentrated in each search space.

Wherein, the quantity for the PDCCH candidate that the needs of current residual abandon is that third quantity needs to abandon with fixed The sum of candidate detection number of PDCCH difference, it is, if the third quantity that need to currently abandon altogether is 10 times, really Surely the sum of detection number of the PDCCH candidate abandoned is 6 times, then the quantity for the PDCCH candidate that current residual needs to abandon is 4 (needing to detect primary calculate by each PDCCH candidate at this time), when successively abandoning, if to the fixed PDCCH for needing to abandon Candidate the sum of detection number reaches the third quantity, then no longer abandons, such as current determine also needs to abandon 4, loses at this time 2 PDCCH candidates for needing to detect 2 times are abandoned, then the sum of the detection number of the PDCCH candidate abandoned meets needs, then No longer abandon.

It is further detailed below by citing.In the present embodiment, it is incremented by according to first polymerization grade, searches again for sky Between the incremental mode of collection index, calculate the quantity that PDCCH candidate collection abandons.To preferentially abandon the low PDCCH of polymerization grade Candidate reduces the influence of PDCCH candidate higher to polymerization grade.The PDCCH that wherein some polymerization grade needs to abandon is candidate Collective number=min { residue needs the quantity abandoned, the quantity of all PDCCH candidates of the polymerization grade }.If a polymerization The PDCCH candidate of grade is distributed in multiple search space collection, then the PDCCH candidate abandoned passs according to the index of search space collection The sequence of increasing, respectively in each search space collection.For example, search space collection #1 contains the PDCCH that 2 polymerization grades are 2 The PDCCH for being 4 with 2 polymerization grades；PDCCH and 1 polymerization etc. that 2 polymerization grades are 4 is contained in the collection #2 of search space The PDCCH that grade is 8.Need to abandon 4 PDCCH altogether, then the sequence being incremented by by polymerization grade, first discarding polymerization grade are 2 PDCCH it is candidate, i.e. the PDCCH that polymerization grade is 2 in 2 search space collection #1 is candidate；Abandoning polymerization grade again is 4 PDCCH is candidate, concentrates since the PDCCH candidate that polymerization grade is 4 is distributed in two search spaces, therefore abandons 1 search space It is candidate to collect the PDCCH that polymerization grade is 4 in the PDCCH candidate and 1 search space collection #2 that polymerization grade is 4 in #1.On wherein Stating, which need to carry out one-time detection in citing with the PDCCH of search space concentration candidate, illustrates, it is to be understood that if searching PDCCH candidate in the collection #1 of rope space needs to detect 2 times, then is losing the PDCCH time that polymerization grade is 2 in the collection #1 of search space After choosing, the detection number of the PDCCH candidate of discarding has reached third quantity, then can stop abandoning.It is understood that the reality It applies example and following embodiments is by passing through the detection to fixed PDCCH candidate after the determining PDCCH candidate abandoned Whether the sum of number, which reaches third quantity, judges whether to need to continue to abandon PDCCH candidate, when the inspection of the PDCCH candidate abandoned When the sum of survey number reaches third quantity, then it can stop abandoning.

Wherein, for dividing equally among the above being concentrated through citing in each search space and being illustrated.Such as search space It is the PDCCH candidate for being 4 including 2 polymerization grades in 1 that collection, which indexes, and collection index in search space is in 2 is including 2 polymerization grades 4 PDCCH is candidate.It should be search space collection index in 1 if it is candidate to lose the PDCCH that 3 polymerization grades are 4 at this time 2 are abandoned, collection index in search space is to lose 1 in 2.So described divide equally, can be real by the partition process of multiple rounds It is existing, in the partition process of each round, according to the incremental order that search space collection indexes, successively it is arranged 1 in each spatial concentration A PDCCH for needing to abandon, until reaching the total quantity that the polymerization grade needs to abandon.

Second, the 5th of the PDCCH candidate for needing to abandon in each polymerization grade of each search space collection of determination the The step of quantity may include:

By a round or the determination process of multiple rounds, the quantity for needing the PDCCH candidate abandoned is determined, until right Fixed the sum of the detection number for needing the PDCCH candidate abandoned reaches the third quantity；Wherein, the determination of each round In the process, the sequence being incremented by according to polymerization grade, each polymerization grade to be processed of poll, and it is each be polled to it is to be processed poly- It is candidate to close 1 PDCCH for needing to abandon of setting in grade, and at the end of each round, updates the polymerization grade to be processed；

Wherein, it for the sequence being incremented by according to polymerization grade, each polymerization grade to be processed of poll, and is polled to each Polymerization grade to be processed in setting 1 need the PDCCH candidate that abandons to be illustrated by way of example.For example, having polymerization etc. Grade is candidate for 2,4,8 PDCCH, then the PDCCH for first determining that a polymerization grade is 2 is candidate, then determines that a polymerization grade is 4 , then determine that a polymerization grade is 8, above-mentioned is in a wheel, if having carried out the detection of the PDCCH candidate abandoned after a wheel The sum of number is less than third quantity, then needs to carry out the second wheel, until the sum of the detection number of the PDCCH candidate abandoned reaches the Three quantity.

And when the PDCCH candidate that 1 needs abandon is arranged: according to the search space collection rope in the polymerization grade Draw incremental sequence, the search space collection at the candidate place PDCCH that described 1 needs to abandon is determined, alternatively, according to search space The incremental sequence of collection index, determine after the first search space collection and include the polymerization grade PDCCH it is candidate it is first to The search space collection of processing, by the first search space collection to be processed, the PDCCH candidate institute for needing to abandon as described 1 Search space collection, first search space collection are as follows: in current round, in the PDCCH that previous polymerization grade is abandoned Search space collection where candidate；

Continuation be illustrated with the example above, wherein if polymerization grade be 2 PDCCH candidate in search space collection 1, together When polymerization grade be 4 PDCCH candidate in search space collection 1 and search space collection 2 in the presence of, according to search space collection rope Draw incremental sequence, determines the PDCCH candidate's for being 4 including polymerization grade after the search space collection 1 at 2 place of polymerization grade Search space collection 2 is search space collection to be processed.

Wherein for the sequence incremental according to the search space collection index in the polymerization grade among the above, described 1 is determined A search space collection for needing the candidate place the PDCCH abandoned is further detailed.Such as first round in polymerization grade 4 1 discarding is set, and 1 discarding will be arranged in polymerization grade 4 in the second round, can be in 1 discarding of setting of adjacent round According to the incremental order that space collection indexes, the space collection at the candidate place PDCCH of this 1 discarding is set.If in incremental order Next spatial concentration there is no the PDCCH of the polymerization grade is candidate, then continue by the incremental sequence of search space collection index The next space collection of poll.

Wherein, the polymerization grade to be processed be initially include the target time slot all polymerization grades, and it is described It includes: current undiscarded in highest polymerization grade in the polymerization grade to be processed for updating the polymerization grade to be processed When the quantity of PDCCH candidate is less than or equal to 1, which is deleted from the polymerization grade to be processed.

When sum of the PDCCH number of candidates in all search space collection for highest polymerization grade is 1, it is poly- to skip this The discarding of the PDCCH candidate of grade is closed, so that it is guaranteed that search space is concentrated there are the PDCCH number of candidates of highest polymerization grade, The influence to the PDCCH candidate of higher polymerization grade is reduced, the collision probability between different user terminals is reduced.

It is further detailed below by citing.In the present embodiment, the PDCCH that each search space is concentrated is candidate Required detection number is 1, it is to be understood that when the detection number of the PDCCH candidate abandoned needed for encountering is 2, only Need to be by the quantity of PDCCH candidate multiplied by 2, and sum to the detection number for the PDCCH candidate that all determinations have abandoned, According to itself and whether reach third quantity judge whether need continue abandon PDCCH.It is incremented by according to first polymerization grade, but every A each polymerization grade of round needs the PDCCH candidate collection quantity abandoned to be fixed as 1, simultaneously scans for the incremental side of spatial index The discarding of formula progress PDCCH candidate collection.At this time it is possible that the PDCCH candidate collection quantity of highest polymerization grade is all Sum in the collection of search space is 1, then skips the discarding of the PDCCH candidate collection of the polymerization grade, since this wheel with such It pushes away.Such as search space collection #1 contains the PDCCH that PDCCH and 2 polymerization grade that 4 polymerization grades are 2 is 4；Search is empty Between collect #2 in contain the PDCCH that PDCCH and 2 polymerization grade that 2 polymerization grades are 4 is 8.It needs altogether to abandon 5 PDCCH, then the first round abandons polymerization etc. in PDCCH, the 1 search space collection #2 that polymerization grade is 2 in 1 search space collection #1 The PDCCH that polymerization grade is 8 in PDCCH and 1 search space collection #2 that grade is 4.Second wheel abandons 1 search space collection #1 The PDCCH that polymerization grade is 4 in PDCCH, the 1 search space collection #2 that middle polymerization grade is 2.

Third, the 5th of the PDCCH candidate for needing to abandon in each polymerization grade of each search space collection of determination the The step of quantity may include:

It is candidate with the PDCCH of each polymerization grade of each search space collection, as a target object, calculate ratio value With the product of the third quantity and round up, determine the detection number to be discarded for needing to abandon in each target object, In, the ratio value is the ratio of the detection number and the first quantity for the PDCCH candidate that the target object includes；

According to the detection number to be discarded, the quantity for the PDCCH candidate for needing to abandon in each target object is determined, In, if the detection number for needing to abandon in all target objects is more than the third quantity, successively decrease according to first polymerization grade, then Search space collection indexes the sequence successively decreased, and successively reduces by 1 PDCCH for needing to abandon candidate in each target object, until The third quantity is reached to fixed the sum of the detection number for needing the PDCCH candidate abandoned.If wherein reducing by 1 needs After the PDCCH of discarding is candidate, it has been determined that the sum of the detection number of PDCCH candidate that abandons of needs less than third quantity, then lose Abandon PDCCH candidate.

It is wherein used as a target object, calculate the product of ratio value and the third quantity and is rounded up, that is, Candidate required the sum of the detection number of PDCCH for calculating the polymerization grade in a search space collection accounts for the ratio of the first quantity Example works as determination so that relationship determines the detection number abandoned needed for each polymerization grade in each search space collection in proportion After the detection number of required discarding, it can be lost needed for the determination of the detection number according to needed for the polymerization grade in the search space collection The quantity of the PDCCH candidate of abandoning, such as the detection number of discarding needed for the first polymerization grade is 4 in the first search space collection It is secondary, if the PDCCH candidate in the search space collection needs to detect 1 time, need to abandon 4 PDCCH candidates, if the search space PDCCH candidate in collection needs to detect 2 times, then needs to abandon 2 PDCCH candidates.The mode that aforementioned proportion abandons is to avoid Only is abandoned from oligomerization grade to high polymerization grade, shadow of the reduction to the terminal for only needing oligomerization grade in center of housing estate It rings, reduces the missing inspection of PDCCH.Simultaneously as rounding up, the total quantity after often making proportional assignment is greater than minimum institute The quantity that need to be abandoned searches again for space collection and indexes the sequence successively decreased, successively in each target so successively decreasing according to first polymerization grade It is candidate that the PDCCH that 1 needs to abandon is reduced in object, so that the PDCCH candidate of high polymerization grade be retained, is reduced to higher poly- Close the influence of the PDCCH candidate of grade.

It is further detailed below by citing.In this example, it is assumed that needing to abandon m detection time altogether Number, total detection number of the PDCCH candidate for some polymerization grade that some search space integrates then need on the polymerization grade as n It abandonsA detection number, it is candidate further according to the PDCCH in detection number and the search space collection The PDCCH number of candidates that required detection number abandons needed for determining, wherein N is that all PDCCH are waited on all search space collection The sum of detection number, i.e. the first quantity needed for choosing.Due to rounding up, if all polymerizations etc. in all search space collection The detection sub-quantity for needing to abandon in grade has exceeded the third quantity for needing to abandon, then high to Low from polymerization grade according to elder generation, The mode of search space index from high to low, which is successively reduced, abandons 1 PDCCH, until to the fixed PDCCH for needing to abandon Candidate the sum of detection number reaches the third quantity.If after wherein reducing by 1 PDCCH for needing to abandon candidate, it has been determined that The sum of the detection number of PDCCH candidate that abandons of needs be less than third quantity, then abandon PDCCH candidate.For the ease of saying It is bright, it is illustrated so that the PDCCH candidate that each search space is concentrated need to only carry out one-time detection as an example below.Such as search is empty Between collection #1 contain the PDCCH that PDCCH and 2 polymerization grade that 4 polymerization grades are 2 is 4；It is contained in the collection #2 of search space The PDCCH that PDCCH and 2 polymerization grade that 2 polymerization grades are 4 is 8.It needs to abandon 4 detection numbers altogether, counts for the first time It calculates, search space collection #1 polymerization grade needs to abandon for 2Secondary detection number, due to the PDCCH Candidate only to detect 1 time, then the quantity of the PDCCH candidate abandoned is 2, and search space collection #1 polymerization grade needs to abandon for 4Secondary detection number, search space collection #2 polymerization grade need to abandon for 4 Secondary detection number, search space collection #2 polymerization grade need to abandon for 8Secondary detection number, due to It calculates for the first time and needs to abandon 5 detection numbers, greater than 4 detection numbers abandoning, therefore highest polymerization grade is needed, also It is that the PDCCH candidate that search space collection #2 polymerization grade is 8 does not need to abandon, final result is search space collection #1 polymerization grade Need to abandon 2 PDCCH candidates for 2, search space collection #1 polymerization grade needs to abandon 1 PDCCH candidate, search space for 4 Collection #2 polymerization grade needs to abandon 1 PDCCH candidate for 4.

It is understood that the product of above-mentioned calculating ratio value and the third quantity and rounding up, in another reality Applying can be the product for calculating ratio value and the third quantity and is rounded downwards in example, if needing in all target objects at this time The sum of detection number of discarding is less than the third quantity, then is incremented by according to first polymerization grade, searches again for space collection index and is incremented by Sequence, it is candidate successively to increase the PDCCH that few 1 needs to abandon in each target object, until needing to abandon to fixed The sum of the detection number of PDCCH candidate reach the third quantity.

Fourth, it is described from each polymerization grade of each search space collection PDCCH candidate in, select it is described 5th number The PDCCH of amount is candidate, may include:

Third quantity is calculated divided by the quantity of search space collection and is rounded downwards, determines and is abandoned needed for each search space collection The 7th quantity detection number, wherein if the sum of described 7th quantity of each search space collection be less than the third quantity, It then concentrates the quantity of included PDCCH candidate to sort search space collection by the sequence successively decreased according to each search space, presses The sequence successively decreased of sorting successively is concentrated in each search space and additionally abandons a PDCCH candidate, until the 7th quantity it Reach the third quantity with the sum of the detection number with the PDCCH candidate additionally abandoned；

Here, by third quantity divided by the quantity of search space collection, extremely by the detection number mean allocation of required discarding Each search space collection, such as need to abandon 10 detection numbers altogether, 2 search space collection are shared, then each search space Collection abandons 5 detection numbers.There may be insufficient situations due to being rounded downwards, such as need to abandon 10 detections time altogether Number, shares 3 search space collection, then each search space collection abandons 3 detection numbers, also poor one-time detection number, then from searching Concentrate additional abandon once in the maximum search space of rope spatial concentration PDCCH number of candidates.

It is candidate according to the 7th quantity and the PDCCH additionally abandoned, it determines and is abandoned needed for each search space collection PDCCH candidate quantity；

Here, it due to the detection number abandoned needed for learning, such as needs to abandon 4 times, according in the search space collection Every PDCCH candidate in the detection number of PDCCH candidate, such as the search space collection needs to detect 2 times, can calculate acquisition and exist The quantity of the PDCCH candidate of required discarding in the search space collection, i.e., 4 divided by 2, need to abandon 2 PDCCH candidates.

By the index cataloged procedure of a round or multiple rounds, to the PDCCH candidate in each search space collection into Line index is numbered, and according to the sequence that the encoded radio of the index coding successively decreases, determines discarding needed for each search space is concentrated The polymerization grade of the PDCCH candidate abandoned needed for PDCCH is candidate and described, wherein successively decrease in each round by polymerization grade Sequence successively carries out the index to 1 PDCCH candidate in each polymerization grade and encodes, and the encoded radio is by incremental sequence It determines.

Here, it is further detailed by way of example.It has been determined that each search space concentrates the PDCCH for needing to abandon to wait After the quantity of choosing, it is thus necessary to determine that abandoned on which polymerization grade.According to polymerization grade and the PDCCH number of each polymerization grade Amount is indexed coding for every PDCCH candidate, such as can establish a 2-d index, and highest priority is on the right side of matrix Upper angle, priority is minimum in the lower left corner, as shown in the table,

Wherein polymerization grade=1,2,4,8, PDCCH number of candidates are 4,4,2,2 respectively, for upper table for example, its The PDCCH number of candidates that middle polymerization grade is 1 is 4, and the index encoded radio of every PDCCH candidate is respectively 3,7,9,11；According to The PDCCH number of candidates for needing to abandon, according to indexing highest several abandoned.To realize more discarding PDCCH The more PDCCH of number of candidates is candidate, and it is candidate more to abandon the lower PDCCH of polymerization grade, to reduce to higher The influence of the PDCCH candidate of grade, while being unlikely to the candidate all discardings of the PDCCH of a certain polymerization grade also maintaining portion Divide the lower PDCCH of polymerization grade candidate, reduces the shadow to the terminal for only using the lower PDCCH candidate of polymerization grade in cell It rings.

Through the foregoing embodiment, illustrate how to determine the PDCCH candidate abandoned needed for each polymerization grade quantity and its Affiliated search space collection, but due to may be due to the quantity of the PDCCH candidate of the polymerization grade in affiliated spatial concentration Greater than the quantity of discarding needed for the polymerization grade, so also need to determine that the PDCCH candidate abandoned exists according to the second preset rules Position in affiliated search space.

Wherein, it is described from each polymerization grade of each search space collection PDCCH candidate in, select it is described 5th number The PDCCH of amount is candidate, may include:

Since the PDCCH candidate of the predeterminated position in each polymerization grade of each search space collection, between default Every the PDCCH for selecting the 5th quantity is candidate；

Wherein the PDCCH candidate of the predeterminated position can be the starting in the polymerization grade of the search space collection PDCCH is candidate or other positions, such as the 2nd, the 3rd PDCCH candidate.0 can be for preset interval, that is, from searching First PDCCH candidate initial position of the rope spatial concentration polymerization grade starts continuously to abandon.Certain preset interval can also be with Other natural numbers, allow to since first PDCCH candidate initial position that the polymerization grade is concentrated in search space by Preset interval abandons.Such as setting 1 for preset interval, then first PDCCH candidate of the polymerization grade is concentrated in search space Initial position starts every a discarding PDCCH candidate, until reaching the 4th quantity.Wherein in one embodiment, preset interval It is that spacing value is obtained according to preset formula q/Q, wherein q is the quantity abandoned needed for the polymerization grade, and Q is the polymerization grade at this The total quantity that search space is concentrated, such as the PDCCH candidate that 4 polymerization grades are 2 is shared in search space collection 1, it needs to lose Abandon 2, then between be divided into 2, then between the first discarding position and the second discarding position between be divided into 2, such as lose first and third It is a, when abandon do not meet four quantity yet to last position when, then the start bit concentrated by the polymerization grade in the search space Continuation is set to be abandoned according to the preset interval.

Alternatively,

Based on one using terminal iidentification and/or slot index as the preset function of variable, the every of each search space collection is calculated The position for the PDCCH candidate for needing to abandon in a polymerization grade, and according to the position being calculated, select the 5th quantity PDCCH it is candidate.

When wherein due to being abandoned by the way of preset interval, it may cause different terminals and abandoned in identical position PDCCH is candidate, this these terminal can only be dispatched in limited section so as to cause base station, is equivalent to that limit base station scheduling more The scope of resource of the PDCCH of a terminal.So in embodiments of the present invention, can also by one based on terminal iidentification and/or when The preset function of gap serial number variable, the position abandoned needed for calculating.Wherein the preset function is preferably random function, for The position abandoned needed for each passes through the random function and carries out calculating acquisition, to realize what different terminals was abandoned PDCCH position candidate is random.Introduce randomized function, it is possible to reduce the collision probability between different user.It is understood that For terminal and benchmark, when based on same terminal iidentification and/or slot index being variable, the position result that the two is obtained is It is identical.
