Specific embodiment

To make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawing to of the invention specific real Example is applied to be described in further detail.It is understood that specific embodiment described herein is used only for explaining the present invention, Rather than limitation of the invention.It also should be noted that illustrating only for ease of description, in attached drawing related to the present invention Part rather than full content.

In order to convenient for explanation, combine channel collision treatment mechanism first hereinafter, elaborates existing SR and send plan Major defect slightly.

Due to the side UE under 5GNR up channel can first, in accordance with preset hit-treatment agreement, by being collided between PUCCH, It is sent after being collided between PUCCH and PUSCH.Therefore, introduce first collide between PUCCH and PUCCH and PUSCH between touch It hits.

It is collided between PUCCH: before PUCCH collision, may have a plurality of types of PUCCH in a time slot, have and only send out Send HARQ-ACK (Hybrid Automatic Repeat request-Acknowledgement, hybrid automatic repeat-request- Confirmation message) PUCCH, have a sending cycle or semi-static CSI (Channel State Information, channel status Information) PUCCH, for example, only send PCSI (Partial Channel State Information, partial channel-state letter Breath) also there is the PUCCH for only sending SR, when the overlapping of any two PUCCH time domain, it is necessary to which applying rules use new PUCCH The PUCCH channel of overlapping is covered, specific judgment criterion is as follows:

When at least sending time domain overlapping there are two PUCCH channel, first to all PUCCH according to time-sequencing, channel Middle primary sign it is forward come front, if primary sign is the same, select the duration it is long come front.If at least The primary sign of two PUCCH channels and duration, all then putting in order for above-mentioned at least two PUCCH channel can be with Arbitrarily.

Step 1: since first PUCCH, first overlay region is found.As first PUCCH and Article 2 PUCCH When being overlapped and there is setting overlay region, then seeing Article 3 PUCCH again, and if first PUCCH is in above-mentioned setting overlay region Overlapping, if overlapping, then see Article 4 PUCCH, and if first PUCCH is overlapped area overlapping in above-mentioned setting, and so on. If first PUCCH and Article 2 PUCCH are not overlapped, from terms of Article 2 PUCCH.On first overlay region, that is, time most The early region including at least at least two PUCCH.

Step 2: it to whole PUCCH in first overlay region, is carried in these overlay regions using a new PUCCH All UCI (Uplink Control Information, control information).Certain new PUCCH is also possible to overlay region In an existing PUCCH, specific alternative rule is no longer unfolded here.

Step 3: new PUCCH enters resource pool, repeats step 1, all only the processing time is upper earliest for each iterative process First overlay region.

Processing schematic when colliding between a kind of PUCCH is shown in fig 1 a to assist in this example with 38-211 For the time slot format under conventional CP (Cyclic Prefix, cyclic prefix) in view is 45.As shown in Figure 1a, the format 45 Last 6 symbols of time slot be uplink symbol, have and send opportunity using 3 SR of same frequency resource, the period is 2 symbols Number, each SR persistently sends a symbol.Each box represents a symbol.

In this, there are 6 PUCCH, first overlay region is PUCCH1, PUCCH2 and PUCCH3 exemplary first round, Accordingly PUCCH7, which can be used, replaces this 3 channels；In the second wheel, there are PUCCH7, PUCCH4, PUCCH5 and PUCCH6, the One overlay region is PUCCH4 and PUCCH5, after rule judgement, carries PCSI and SR simultaneously using PUCCH4, and using should New PUCCH4 replaces original PUCCH4 and PUCCH5.In third round, there are PUCCH7, PUCCH4 and PUCCH6, mutually Between be no longer overlapped, the collision process between PUCCH terminates.

It is collided between PUCCH and PUSCH: according to collision agreement, when PUCCH overlaps with the PUSCH with data, The SR that PUCCH is carried above can be dropped, other UCI on PUCCH, which can be gone on PUSCH, to be carried, and abandons the PUCCH；And When the PUSCH of the PUCCH for carrying positive SR and carrying AC SI collision, the PUSCH is abandoned.

Still with remaining PUCCH channel citing above, as shown in Figure 1 b: before the collision, there are 3 PUCCH and 2 PUSCH, But after colliding, PUCCH7 withers away, and the HARQ-ACK and PCSI carried above is gone on PUSCH1, and the SR carried on PUCCH7 is lost It abandons；In addition, the PUSCH2 for only carrying ACSI is overlapped with the PUCCH6 time domain for carrying positive SR.Therefore, PUSCH2 withers away.

From Fig. 1 a and Fig. 1 b, it is apparent that if we take the first tactful, in sending time earliest SR, may be after channel collision, which has been dropped.If 3 SR of initial selected are sent, to the end when A PUSCH of carrying AC SI is also resulted in be dropped.

In addition, inventor is combining channel (signal in other words) quality analysis for the PUCCH for being actually reached base station to obtain: such as Fruit selection only sends a time upper earliest SR, even if not being dropped, but if channel quality is poor to be caused at SR signal When near demodulation threshold, there can be the possibility of missing inspection.If selecting all SR chances all to send, in channel quality When preferable, then the SR signal of each chance can successfully be detected, and there are repeated and redundants, and there is also channels to do to other UE It disturbs.

In conclusion the scheme of the prior art has the following problems:

1, when uplink PUCCH channel quality is poor, the initial scheme for only sending out a SR is taken in a time slot, is existed The possibility of base station missing inspection；

2, the initial scheme for only sending out a SR is taken in a time slot, there is and have the overlapping of PUSCH data channel, it should The risk that PUCCH is dropped；

3, when uplink PUCCH channel quality is preferable, the scheme for sending multiple SR is taken in a time slot, there are repetitions The redundancy of detection, while unnecessary transmission SR, will form the noise jamming of the user poor to channel quality；

4, all there is the PUSCH quilt when the PUCCH for carrying SR is Chong Die with the PUSCH for only carrying ACSI in all schemes The risk of discarding.

It is now that the EMBODIMENTS OF THE INVENTIONIn of the embodiment of the present invention is as follows based on the defect of the above-mentioned prior art:

Embodiment one

Fig. 1 c is a kind of flow chart of the sending control method for uplink scheduling request that first embodiment of the invention provides, this Inventive embodiments during multiple SR transmission opportunitys suitable for filtering out preferred the case where sending opportunity, especially suitable for the super of 5GNR The transmission for the SR in TDD (time division duplex, Time Division Duplexing) scene that high reliability is communicated with ultralow time delay Process.The method of the present embodiment can be executed by the transmission control device of uplink scheduling request, the device can by hardware and/ Or the mode of software is realized, can be generally integrated in UE side apparatus, is used cooperatively with base station equipment.

As illustrated in figure 1 c, the method for the present embodiment specifically comprises the following steps:

Step 110 existing at least two sends opportunitys in a time slot according to SR to be sent, generates described in carrying At least two alternative PUCCH of SR；Wherein, less than one time slot of the period of the SR.

Wherein, the period of the SR specifically refers to the transmission time interval between continuous two SR.

Firstly, it is necessary to which explanation is that the technical solution of the embodiment of the present invention is primarily adapted for use in the ultrahigh reliability of 5GNR and super In the TDD scene of low time delay communication, in above-mentioned application scenarios, less than one time slot of period of SR, usually 2 symbols, because This, can there is the transmission opportunity of more than one SR in one time slot.

In the present embodiment, it is primarily based on a plurality of alternative PUCCH of existing multiple transmission opportunitys generations in a time slot It is (that is, an alternative PUCCH corresponding transmission opportunity), a plurality of alternative to this based on downlink signal quality metric later PUCCH carries out channel screening, to retain PUCCH that is optimal and carrying the SR.Continuous precedent, as shown in Figure 1a, by Syb7- In this time slot that Syb13 is constituted, 6 uplink symbol Syb8-Syb13 are shared, in long (the lasting hair of transmission window for determining a SR Send the time) be a symbol, and the sending cycle between SR be 2 symbols when, can determine the transmission opportunity of three SR, that is, Syb8 character position, Syb10 character position and Syb12 character position.Three alternative PUCCH accordingly can be generated, namely: PUCCH2, PUCCH5 and PUCCH6.

It in general, can be by SR (for example, sending positive SR) to network side when the side UE has upstream data to need to transmit (alternatively referred to as base station side) applies for that resource is transmitted for new data.SR belongs to the information of physical layer, and the side UE is transmitted by PUCCH SR, PUCCH are required to occupy RB (Resource Element, resource particle) resource, for example, needing to occupy for format0 1 RB resource.

Correspondingly, can determine that meeting SR sends condition, and then can basis when the side UE has upstream data to need to transmit SR to be sent existing at least two transmission opportunity, at least two for generating the carrying SR in a time slot are alternative PUCCH。

Correspondingly, in an optional embodiment of the present embodiment, according to SR to be sent in a time slot memory At least two send opportunitys, generate and carry at least two alternative PUCCH of the SR and may include:

When detecting that meeting SR sends condition, SR attribute description information is obtained；Wherein, the SR attribute description packet Include: it is long that at least two optional symbol insertion positions and SR of the SR in a time slot of the data frame of preset format send window；

Whenever determine reach time point matched with an optional symbol insertion position when, it is long that window is sent according to the SR, The alternative PUCCH of a carrying SR is generated, until generating alternative with all optional matched wholes in symbol insertion position PUCCH。

Wherein, the data frame of the preset format can be determined by the side the UE configuration file that base station side is first sent out in advance, tool Body, the preset format can be the various time slot formats under the conventional CP in 38-211 agreement (for example, time slot 34- time slot 42 or time slot 45 etc.), wherein in above-mentioned various time slot formats, the uplink symbol number needs for including in a time slot are greater than Equal to 3, to guarantee under the time slot format, the transmission opportunity of at least two SR can be determined in a time slot.

Wherein, the SR attribute description information can specifically be determined by the static configuration information that base station side is sent, and one It is remained unchanged in the time of Duan Wending, until receiving RRC (Radio Resource Control, the wireless money of base station side transmission Source control) information, and currently stored static configuration information is updated based on the rrc message, and then can be according to this more Static configuration information after new, is updated the SR attribute description information.Wherein, above-mentioned SR attribute description information is for making The side UE uniquely determines and generates and the matched alternative PUCCH of each optional symbol insertion position (the transmission opportunity of SR).

Step 120, according to downlink signal quality metric, and with other associated PUCCH of the alternative PUCCH and/ Or PUSCH, redundancy PUCCH is screened out at least two alternative PUCCH.

As previously mentioned, can be seen that in conjunction with uplink signal-channel quality when uplink signal-channel quality is poor, if the carrying sent The PUCCH of positive SR is less, then is likely to result in the missing inspection of the PUCCH；When uplink signal-channel quality is preferable, if the carrying sent The PUCCH of positive SR is more, then is likely to result in repeated and redundant, and there is also channel disturbances to other UE.

Since uplink signal-channel quality can obtain (obtaining by measuring quality of uplink signal metric measured by base station side To), and can not be obtained by the simple and quick measurement in the side UE, the proposition of inventor's creativeness: according to the channel reciprocity of TDD, make Corresponding quality of uplink signal metric is replaced with downlink signal quality metric, with the current uplink signal-channel quality of determination, into And it can select to screen out redundancy PUCCH at least two alternative PUCCH when uplink signal-channel quality is preferable.The redundancy In PUCCH namely multiple alternative PUCCH, the PUCCH of repeated and redundant will cause.

Wherein, the downlink signal quality metric may include: downlink signal SNR (SIGNAL-NOISE RATIO, letter Make an uproar ratio) and/or RSRP (Reference Signal Receiving Power, Reference Signal Received Power) etc. can be used to Downlink signal quality is measured, in other words the numerical value of down channel quality.

Optionally, according to downlink signal quality metric, and with other associated PUCCH of the alternative PUCCH and/or PUSCH screens out redundancy PUCCH at least two alternative PUCCH, may include:

By the alternative PUCCH, channel collision is carried out with the alternative PUCCH other associated PUCCH and/or PUSCH Processing generates collision result；

According to downlink signal quality metric and the collision as a result, being screened out from described at least two alternative PUCCH The redundancy PUCCH.

Optionally, with associated other PUCCH and/or PUSCH of described at least two alternative PUCCH, be specifically as follows with The alternative PUCCH is in same time slot, and sending time is possible to other PUCCH of overlapping (for example, only sending HARQ- The PUCCH of ACK, perhaps only send PCSI PUCCH etc.) either PUSCH (for example, with data PUSCH or only carry The PUSCH etc. of ACSI).

In the present embodiment, can be first by the alternative PUCCH, and other associated PUCCH of the alternative PUCCH, And/or PUSCH carries out the hit-treatment of channel, generate collision as a result, namely channel pre-impact, and before carrying out pre-impact Above-mentioned at least two PUCCH and associated other PUCCH and/or PUSCH of the alternative PUCCH are stored in advance, with It realizes after being screened out to redundancy PUCCH, the alternative PUCCH after redundancy PUCCH and other described PUCCH will be screened out again And/or PUSCH is collided again, and corresponding collision result is sent to base station side.

Step 130 will screen out the alternative PUCCH after redundancy PUCCH and be determined as practical PUCCH.

Wherein, the practical PUCCH was specifically referred to according to downlink signal quality metric from the transmission opportunity with whole SR The preferred PUCCH that corresponding whole PUCCH is filtered out.

The embodiment of the present invention according to SR in a time slot existing multiple transmission opportunitys generate it is corresponding multiple alternative After PUCCH, according to downlink signal quality metric, and with associated other PUCCH and/or PUSCH of the alternative PUCCH, After screening out redundancy PUCCH at least two alternative PUCCH, practical PUCCH is obtained in a manner of carrying out SR transmission, passes through channel Reciprocity, the transmission environment of uplink signal, and the biography based on the uplink signal are determined using downlink signal quality metric Defeated environment selectively deletes the redundancy PUCCH in all alternative PUCCH, while guaranteeing that SR is effectively sent, The transmission redundancy for reducing SR to the greatest extent, realizes the compromise of SR transmission availability and reliability.

Embodiment two

A kind of stream of the sending control method of uplink scheduling request provided by Embodiment 2 of the present invention is shown in fig. 2 a Cheng Tu.The present embodiment is optimized based on above-described embodiment, in the present embodiment, by step by the alternative PUCCH, with Described associated other PUCCH and/or PUSCH of alternative PUCCH carry out channel collision processing, generate collision result；And step According to downlink signal quality metric and the collision as a result, screening out the redundancy from described at least two alternative PUCCH PUCCH is advanced optimized.

As shown in Figure 2 a, the method for the present embodiment specifically comprises the following steps:

Step 210 existing at least two sends opportunitys in a time slot according to SR to be sent, generates described in carrying At least two alternative PUCCH of SR；Wherein, less than one time slot of the period of the SR.

Step 220, using the first hit-treatment rule, channel is carried out to the alternative PUCCH and other described PUCCH Hit-treatment generates and collides PUCCH among at least one.

Specifically, the first hit-treatment rule specifically refers to as previously described: when being determined in all alternative PUCCH Between overlay region, whole PUCCH in time-interleaving area carry all UCI in these overlay regions using a new PUCCH (Uplink Control Information controls information).Certain new PUCCH has been also possible to one in overlay region Some PUCCH.

Step 230, using the second hit-treatment rule, channel collision is carried out to the intermediate collision PUCCH and PUSCH Processing, PUSCH is as the collision result after generating PUCCH after collision, and/or collision.

Specifically, the second hit-treatment rule specifically refers to as previously described: the PUCCH and PUSCH for having data When overlapping, the SR that PUCCH is carried above can be dropped, other UCI on PUCCH, which can be gone on PUSCH, to be carried, and is abandoned The PUCCH；And when the PUSCH of the PUCCH for carrying positive SR and carrying AC SI collision, abandon the PUSCH.

Step 240 judges whether downlink signal quality metric meets preset threshold condition, if so, executing step 250；Otherwise, step 260 is executed.

As previously mentioned, when uplink signal-channel quality is bad, if the PUCCH of the positive SR of carrying sent it is less when, may It will cause the missing inspection of PUCCH.Therefore, in the present embodiment, if according to downlink signal quality metric (for measuring uplink letter The parameter of road quality) determine that uplink signal-channel quality is poor, then redundancy can not be screened out from above-mentioned at least two alternative PUCCH PUCCH, but only when determining that uplink signal-channel quality is preferable according to the downlink signal quality metric, it is standby from above-mentioned at least two It selects and screens out redundancy PUCCH in PUCCH.

Typically, the downlink signal quality metric (for example, downlink SNR or RSRP) can be used directly to measure Uplink signal-channel quality, that is, downlink signal quality metric is bigger, uplink signal-channel quality is better.Correspondingly, can be prespecified When downlink signal quality metric is more than or equal to setting threshold value, determination meets the preset threshold condition；When downlink is believed When number quality measurement is less than setting threshold value, determination is unsatisfactory for the preset threshold condition.

Such as, if it is determined that downlink signal quality metric is SNR, then can specify that the SNR obtained when measurement is greater than When threshold T 1, determination meets the threshold condition, alternatively, determining when the RSRP that measurement obtains is more than or equal to threshold T 2 Meet the threshold condition etc..

Step 250, according to chronological order, the first object of first positive SR of carrying is obtained in the collision result PUCCH executes step 270.

The collision result is directly sent to the base station side by step 260.

As previously described, if it is determined that downlink signal quality metric is to be unsatisfactory for preset threshold condition, then can be complete The PUCCH for carrying positive SR is sent under portion's transmission opportunity, and then above-mentioned collision result can be sent directly to the base station side, To guarantee in the case where uplink signal-channel quality is bad, enable to the positive SR that can be received with maximum probability by base station side It arrives.

Step 270, continue to test in the collision result with the presence or absence of the time be located at the first object PUCCH it Afterwards, and only the second target PUCCH of positive SR is carried: if so, executing step 280；Otherwise, 260 are returned to step.

In the present embodiment, when determining that uplink signal-channel quality is preferable, when needing whole transmissions with SR as far as possible The redundancy PUCCH for including in the corresponding at least two alternative PUCCH of machine is screened out.

Specifically screen out mode are as follows: obtain the positive SR of a carrying and time in collision result first near preceding one PUCCH (that is, first object PUCCH), above-mentioned first object PUCCH can carry or not carry HARQ-ACK, Huo Zheye Can carry or not carry PCSI etc..If above-mentioned under one or more time point after first object PUCCH Colliding also correspondence in result includes the PUCCH (that is, second target PUCCH) for comprising only positive SR, then illustrates above-mentioned Second target PUCCH is not be overlapped with any other PUCCH or PUSCH, in other words during channel collision because this The presence of two target PUCCH, the PUSCH for only sending ACSI are dropped.Because uplink signal-channel quality at this time is preferable, there is no need to Redundancy sends said one or multiple second target PUCCH, therefore, can be based on existing multiple SR in a time slot Send opportunity generate alternative PUCCH in, above-mentioned redundancy PUCCH is deleted.

In addition, it is necessary to it is once more emphasized that, when determining that meeting SR sends opportunity, the PUCCH tool of transmitted carrying SR Body refers to the PUCCH for carrying positive SR (base station side is needed to distribute resource).However in the subsequent multiple channels carried out in same time slot Collision process in, may include the PUCCH of the negative SR of carrying (not needing base station side distribution resource), therefore, the present invention is real Example is applied when obtaining first object PUCCH, therefore, to assure that the PUCCH including positive SR is filtered out, to guarantee the needs base station side point Information with resource can be sent.Likewise, for the Effective selection to the SR information, the second target of subsequent acquisition PUCCH is the PUCCH for comprising only positive SR.

Step 280, all the second target PUCCH that will test out are carried out from the alternative PUCCH as redundancy PUCCH It screens out.

Step 290 will screen out the alternative PUCCH after redundancy PUCCH and be determined as practical PUCCH.

Step 2100, using the practical PUCCH again with other associated PUCCH of the alternative PUCCH and/or PUSCH carries out channel collision, generates new collision result.

The new collision result is sent to base station side by step 2110.

Further it will be understood that not including this in the collision result that is likely to be obtained after executing and completing step S230 First object PUCCH, therefore, also with regard to being not necessarily in the necessity deleted redundancy PUCCH, because in collision result inherently not It include the PUCCH for carrying positive SR, accordingly it is also possible to which above-mentioned collision result is directly sent directly to base station side.

For the beneficial effect of the more intuitive statement embodiment of the present invention, show in Fig. 2 b using the embodiment of the present invention Method after, the processing of a plurality of PUCCH and other PUCCH and/or PUSCH of SR when colliding is carried in a time slot Schematic diagram.Wherein, in the scene of Fig. 2 b, pre-suppose that downlink signal quality metric meets preset threshold condition.

As shown in Figure 2 b, after completing initial collision (that is, by least two alternative PUCCH and associated PUCCH and After PUSCH carries out initial collision), PUCCH4 is the time near preceding, and includes a PUCCH of positive SR (that is, the first mesh Mark PUCCH), in the PUCCH after time point is located at first object PUCCH, detection discovery further includes having only to carry positive SR PUCCH6 (that is, second target PUCCH) therefore can be re-started by above-mentioned PUCCH6 after deleting in alternative PUCCH Alternative PUCCH and associated PUCCH and PUSCH collision again (specific collision process a and Fig. 1 b referring to Figure 1, this In repeat no more).From in Fig. 2 b, it is apparent that again collide after, not only SR can normally be sent, before because collision And abandon, only the PUSCH2 of carrying AC SI can similarly be sent.

That is, technical solution through the embodiment of the present invention, above-mentioned 4 problems existing for prior art have obtained base This solution.

Namely: it is initially only sent out once for when uplink signal-channel quality is poor, being taken in a time slot in the prior art The scheme of SR, there are the possibility of base station missing inspection；The scheme of this programme inventive embodiments can be sent under the transmission opportunity of multiple SR Repeatedly, in this scenario, the PUSCH for only sending ACSI would rather be removed, also to guarantee that SR is sent.

For the initial scheme for only sending out a SR is taken in a time slot in the prior art, there is and have PUSCH number It is believed that trace overlap, the risk which is dropped；It is the scheme initial selected of the embodiment of the present invention multiple transmission opportunitys, final defeated It can guarantee that the time for meeting condition upper earliest SR can be sent in result always out, certainly, all in addition to all transmission opportunitys With the scene of the PUSCH channel overlap with data, at this point, the PUCCH can be equally dropped, still, drop probability is big It is big to reduce.

For when uplink signal-channel quality is preferable, the scheme for sending multiple SR is taken in a time slot in the prior art, In the presence of the redundancy for repeating detection, while unnecessary transmission SR will form the noise jamming of the user poor to channel quality；This The technical solution of inventive embodiments only sends out a SR, and is earliest SR under terms of agreement satisfaction.

All schemes all presence for the prior art ought carry the PUCCH of SR and only carry the PUSCH weight of ACSI When folded, risk that PUSCH is dropped；The technical solution of the embodiment of the present invention only carries the PUSCH of ACSI in PUCCH collision When, if the PUCCH meets: non-first PUCCH comprising positive SR, and be the PUCCH for only carrying positive SR, the PUCCH is abandoned, The PUSCH for the PUCCH time-interleaving that can make and abandon still is sent.The problem can obtain effectively under the scene of part It solves.
