The disclosure is described in detail combined with specific embodiments below:
UE needs to occupy certain transmission power when sending uplink, limit of the transmission power no more than maximum power System.It is greater than 1 multiple transmission (transmission) for quantity, when having overlapping (overlapping) in time, needs full The sum of the power of the multiple transmission of foot is not more than the condition of maximum power.Have in time overlapping can refer to multiple transmission all or Person partly shares a period of time, multiplex mode including but not limited to below: frequency division multiplexing (FDM), code division multiplexing (CDM), Space division multiplexing (SDM).The transmission refers to that occupying particular channel resource sends corresponding information, for example, data packet 4 OFDM symbols (OFDM symbol, hereinafter simply also referred to as symbol indicate a Duan Shichang) for needing to occupy PUSCH are sent, this 4 The PUSCH of a symbol is referred to as a PUSCH transmission.Similarly, there is also the transmission of PUCCH, the transmission of SRS, PRACH biography It is defeated.There is likely to be the transmission of long PUCCH, the transmission of short PUCCH, the transmission of long PUSCH, the transmission of short PUSCH.It is also possible to deposit In the transmission of different classes of SRS.
If multiple transmission overlapping parts send power limit beyond maximum, first guarantee Gao You by predefined priority The transmission power of the transmission of first grade carries out power extraction (power scaling) to the transmission of low priority.
As shown in figure 5, the transmission of PUSCH occupies OFDM symbol #1~#9, the transmission of PUCCH occupies OFDM symbol #6~# 10.Only consider the two transmission, for PUSCH transmission, the part overlapping is symbol #6~#9, non overlapping Part is #1~#5, and PUCCH is transmitted, and the part overlapping is symbol #6~#9, and the part non overlapping is # The transmission power that 10.PUSCH needs is set as P1, and the transmission power that PUCCH needs is set as P2, in the part overlapping, the two The sum of power P1+P2 be more than that the maximum of UE sends power limit P_max.Assuming that the transmission priority ratio of PUCCH herein The transmission priority of PUSCH is high, then the transmission power of UE preferentially meets the power of PUCCH, then PUSCH transmission exists The transmission power maximum of the part overlapping can only be P_max-P2, the power P 1 needed less than transmission.For PUSCH's The part non overlapping, convenience when PUSCH received from receiving end consider, it is therefore desirable in the transmission of entire PUSCH Phase keeps power consistent, that is, needs to use the same power scaling with the part overlapping.
Power scaling, which is also referred to as power extraction or power adjustment or power, to be reduced.Power phase adjusted Power scaling coefficient or power regulation factor, power extraction coefficient are known as the ratio of former power.PUSCH's Transmission power after the power scaling of the part overlapping is P_max-P2, and power scaling coefficient is (P_ max-P2)/P1。
Although this processing method is simple, power efficiency is not high, according to lap (part overlapping) Demand, which carries out power extraction to non-overlap part (part non overlapping), will lead to the part non overlapping The case where power reduces, and demodulation performance is affected, and accounts for transmission phase ratio very little particularly with the part non overlapping should Problem is more prominent.In addition, this processing method is also unfavorable for the stationarity of power amplifier (PA), because reducing non The power of the part overlapping, so that becoming larger between symbols with power difference.
It is unbalanced for existing overlapping part among the above and the power of non-overlapping part, it will lead to receiving end and be difficult to locate The problem of managing, or even cannot demodulating；And if non-overlapping part reduces mode, and meeting using the power as overlapping part The problem of leading to the power efficiency of this part reduces；The present embodiment uses following technical scheme:
First determine whether the time domain overlapping cases of transmission, then when underpower occurs for time domain lap, i.e., at least One transmission needs power to cut down, i.e. power extraction coefficient judges the power extraction of the time domain lap of the transmission less than 1 Whether mode is identical as the power extraction mode of the other parts of the transmission, or judges the function of the time domain lap of the transmission Rate cuts down the other parts whether coefficient is applied to the transmission.It is specific as follows:
Whether the transmission of one: greater than 1 quantity of situation has time domain overlapping overlapping anticipated that, that is, It can at least be known when slot s lot starts in the slot either with or without overlapping, include whether URLLC business (Ultra Reliable Low Latency Communications, highly reliable low time delay communication)；
Situation two: overlapping is burst, i.e., whether can not predict can occur time domain overlapping.? In predefined transmission time, determine that the part overlapping is (corresponding to time domain overlapping region among the above) and non- The part overlapping (corresponding to non-temporal overlapping region among the above).
When multiple transmission have time domain overlapping (overlapping or overlapping or time domain are overlapping or overlapping), time domain The length of overlapping region is as unit of symbol.It is with each especially when the symbol lengths that multiple transmission use may be different The symbol of a transmission oneself is unit.
For a certain transmission, the determination method whether various pieces in the transmission phase belong to time domain overlapping region is as follows:
Than above-mentioned transmission (it is assumed that transmission one (corresponding to the first transmission among the above)) the high transmission of priority (it is assumed that For transmission two (corresponding to the second transmission among the above)) with the time domain lap of the transmission be known as the transmission (transmitting one) with it is right The time domain overlapping region of (transmission two) should be transmitted.
The priority ratio transmission one of above-mentioned hypothesis transmission two is high, therefore the time domain overlapping portion for transmission two, with transmission one Dividing not can be regarded as time domain overlapping region.
For a certain transmission (it is assumed that transmission one), higher than its priority has multiple transmission (it is assumed that transmission two, transmission Three), for transmission one, time domain overlapping region may be according to the time domain overlapping combinations from different transmission and including multiple time domains Overlapping region.Such as transmit the time domain lap further division of one with transmission two and transmission three are as follows: transmission one and transmission two Time domain overlapping region, transmission one with transmission three time domain overlapping region, transmission one with transmission two and transmit three time domain weight Folded region.
Other parts in above-mentioned transmission other than time domain overlapping region are non-temporal overlapping regions.
It is exemplified below: having 3 transmission, transmission 1, transmission 2, transmission 3, priority is from high in the end.
Transmission 1: symbol 0,1,2 is occupied
Transmission 2: symbol 2,3,4,5 is occupied
Transmission 3: symbol 0,1,2,3,4,5,6,7,8 is occupied
1 highest priority is transmitted, all symbols belong to non-temporal overlapping region；
Transmission 2 is the second priority, needs to consider the transmission 1 and oneself time domain overlapping cases higher than oneself priority, Such as, symbol 2 is time domain overlapping region, and symbol 3,4,5 is non-temporal overlapping region；
Transmission 3 is third priority, and transmission 3 and the time domain lap of transmission 1 are symbols 0,1, transmission 3 and transmission 2 Time domain overlapping region is symbol 3,4,5, and transmission 3 and the time domain overlapping region of transmission 1 and transmission 2 are symbols 2, and symbol 6,7,8 It is non-temporal overlapping region.
When a certain transmission has multiple time domain overlapping regions, each time domain overlapping region determines the power of transmission respectively.Tool Body, according in the demand power of transmission, the time domain overlapping region than the high all transmission of priority transmitted demand power, The maximum allowable power of the time domain overlapping region determines the power of the transmission.When subtracting this with the maximum allowable power The demand power of all transmission higher than the priority transmitted in the overlapping region of domain, obtains the maximum power that transmission is allowed to.By The maximum power that the demand power of transmission and transmission are allowed to, obtains the power that the transmission can be assigned to.That is, above-mentioned transmission can be with The power assigned to is the smaller value in the demand power of maximum power and transmission that transmission is allowed to.
When carrying out above-mentioned processing to some time domain overlapping region of a certain transmission, if in the transmission region there is also with The identical transmission of the priority of above-mentioned transmission, then according to the demand power of above-mentioned transmission, institute identical with above-mentioned transmission priority The demand function of the demand power, all transmission higher than the priority of above-mentioned transmission in the time domain overlapping region that there are other to transmit Rate, the time domain overlapping region maximum allowable power determine the power of above-mentioned transmission.That is, being subtracted with above-mentioned maximum allowable power The demand power of all transmission higher than the priority of above-mentioned transmission, obtains excellent on an equal basis with above-mentioned transmission in the time domain overlapping region The maximum power that all transmission of first grade are allowed to.By the sum of the demand power of all transmission with above-mentioned transmission All factors being equal, preference will be give to grade The maximum power being allowed to all transmission with above-mentioned transmission All factors being equal, preference will be give to grade, obtains the power that the transmission can be assigned to.That is, The sum of the power that all transmission with above-mentioned transmission All factors being equal, preference will be give to grade can be assigned to are as follows: all with above-mentioned transmission All factors being equal, preference will be give to grade The smaller value in maximum power that the sum of demand power of transmission is allowed to all transmission with above-mentioned transmission All factors being equal, preference will be give to grade.
When the sum of the power that all transmission with above-mentioned transmission All factors being equal, preference will be give to grade can be assigned to be less than it is same with above-mentioned transmission When the sum of the demand power of all transmission of priority, the transmission of all or part of All factors being equal, preference will be give to above-mentioned transmission grade needs Carry out equal proportion power extraction.Transmission if it is part and above-mentioned transmission All factors being equal, preference will be give to grade carries out equal proportion power extraction, Then power with other transmission of above-mentioned transmission All factors being equal, preference will be give to grade are zero.
When a certain transmission there are multiple time domain overlapping regions, each time domain overlapping region is determined respectively according to the above aspect The power of transmission.
Power is determined also that non-temporal overlapping region.Specifically, the power of non-temporal overlapping region are as follows: the region is most Smaller value in the big demand power for allowing power and the transmission.
Maximum allowable power may be defined on certain frequency domain, such as at least one of, and BWP rank, CC rank are used Terminal UE rank.When defining multiple ranks, then multiple transmission require to meet multiple biographies in frequency domain region in each rank The sum of defeated power is no more than the maximum allowable power that the frequency domain region defines.For example, when multiple transmission belong to a BWP When (bandwidth partial, fractional bandwidth), which may be the maximum allowable power of corresponding BWP；When When multiple transmission belong to a CC, which is the maximum allowable power of the CC；When it is multiple transmission belong to it is multiple When CC, which is the maximum allowable power of multiple CC, it may be possible to the maximum power that UE is allowed to.
The judgement for determining whether to do consistent power extraction to multiple time domain overlapping regions, non-temporal overlapping region, with Above-mentioned time domain overlapping region is similar with the mode whether non-temporal overlapping region does consistent power extraction.That is, according to following At least one information determines the power of the transmission of time domain overlapping region and/or non-temporal overlapping region: the modulating-coding side of transmission Formula, resource ratio, power extraction parameter, the priority of transmission.
Above-mentioned time domain overlapping region may have it is multiple, at this point, the time domain overlapping region that refers to of resource ratio and entire transmission The ratio of duration.
The other parts of overlapping region and transmission use consistent power to be judged whether one by one to multiple time domain overlapping regions Reduction mode.If any one time domain overlapping region of multiple time domain overlapping regions is required with the other parts of transmission using consistent Power extraction mode, then all time domain overlapping regions require use and the consistent power extraction mode of Non-overlapping Domain. At this point, the smallest value of the power extraction coefficient in multiple time domain overlapping regions is taken to be used as consistent power extraction coefficient.
To a certain transmission, if using subregion block mode, the power extraction mode that may be consistent inside each block, Then the range of above-mentioned transmission refers to one or more time domain overlapping region and non-temporal overlapping region inside block.Multiple areas Between block, power method of determination is independent.
Sphere of action of the above power extraction in time domain, it may be possible to following one:
Entire transmission；
Each time domain overlapping region of transmission；
The non-temporal overlapping region of transmission；
Each block of transmission；
In each block of transmission, each time domain overlapping region；
In each block of transmission, non-temporal overlapping region.

Specific embodiment 3
One is transmitted, according to the demand power of the determining transmission of the parameter of at least one of: open Loop Power control parameter, Close-loop power control parameter, path loss PL configuration parameter, the factor of path loss PL.
It determines the time domain overlapping region and non-temporal overlapping region during its transmission, and determines the time domain overlapping of the transmission The power in region and non-temporal overlapping region.
The above time domain overlapping region may include multiple and different time domain overlapping regions, correspond respectively to the transmission and other The combined time domain simultaneous transmission of different transmission.
When above-mentioned transmission is when some or multiple time domain overlapping regions need power to cut down, i.e., in time domain overlay region The power extraction coefficient in domain is less than pre-determined threshold, such as when 1, adjusts time domain overlapping region and/or non-temporal according to resource ratio The power of overlapping region.Method of adjustment is as follows:
If the duration of the duration ratio or time domain overlapping region of time domain overlapping region and non-temporal overlapping region with should The duration ratio of the entire transmission phase of transmission is more than predetermined threshold one, then non-temporal overlapping region is done identical with time domain overlapping region The power extraction of mode；Otherwise, non-temporal overlapping region is unrelated with the power extraction mode of time domain overlapping region.
If the duration of the duration ratio or time domain overlapping region of time domain overlapping region and non-temporal overlapping region with should The duration ratio of the entire transmission phase of transmission is less than predetermined threshold two, then the power of time domain overlapping region is zero.
Above-mentioned predetermined threshold one and predetermined threshold two can be identical, are also possible to predetermined threshold one greater than predetermined threshold two.
For example, to PUSCH transmission, the transmission phase is 9 symbols, and overlapping length is 4 symbols in Fig. 5, if Above-mentioned predetermined threshold is the ratio of the duration of overlapping and the entire transmission phase of the transmission, and thresholding one is set as 1/3, then 4/9 > 1/3, then power of the PUSCH in the part overlapping is P_max-P2, the power of the part non overlapping It is P_max-P2.If the length of overlapping only has 1 symbol, 1/9 < 1/3, PUSCH is in non overlapping 8 partial symbols do not need to do with the symbol of 1 overlapping power scaling.If above-mentioned thresholding two It is set as 1/9, then the ratio of the entire transmission phase of the duration of overlapping and the transmission is less than predetermined threshold two, then It is zero that 1 symbol of the part overlapping, which sends power,.
If the power extraction coefficient of the time domain overlapping region or power of time domain overlapping region is super after power extraction Predetermined threshold three is crossed, then the power extraction of same way is done in non-temporal overlapping region and time domain overlapping region；Otherwise, non-temporal weight Folded region is unrelated with the power extraction mode of time domain overlapping region.
If the power extraction coefficient of time domain overlapping region or after power extraction time domain overlapping region power not More than predetermined threshold four, then the power of time domain overlapping region is zero.
Above-mentioned predetermined threshold three and predetermined threshold four can be identical, are also possible to predetermined threshold three greater than predetermined threshold four.
Transmission power after the above resource ratio and power extraction coefficient or power extraction can be with connected applications.For example, with Lower deterministic process can independently come into force.
Overlapping is power scaling in part on demand, if overlapping and non overlapping Duration ratio or overlapping the duration and transmission the entire transmission phase ratio be more than predetermined threshold one, and If the coefficient of power scaling or the transmission power after power scaling are more than predetermined threshold three, non Overlapping is also power scaling identical with overlapping；Otherwise, the function of the part non overlapping Rate is unrelated with the power scaling of the part overlapping.
Overlapping is power scaling in part on demand, if overlapping and non overlapping Duration ratio perhaps the entire transmission phase of the duration of overlapping and the transmission ratio be more than predetermined threshold one or If the coefficient of power scaling or the transmission power after power scaling are more than predetermined threshold three, non Overlapping is also power scaling identical with overlapping；Otherwise, the function of the part non overlapping Rate is unrelated with the power scaling of the part overlapping.
If the duration ratio of overlapping and non overlapping or the duration of overlapping with should The ratio of the entire transmission phase of transmission is less than predetermined threshold two, and if power scaling coefficient or power Transmission power after scaling is less than predetermined threshold four, then the transmission power of the part overlapping is zero.
If the duration ratio of overlapping and non overlapping or the duration of overlapping with should The ratio of the entire transmission phase of transmission is less than predetermined threshold two, or if power scaling coefficient or power Transmission power after scaling is less than predetermined threshold four, then the transmission power of the part overlapping is zero.
Specific embodiment 4
According to the position DMRS blockette, power scaling is by block；
In order to reduce the coverage of power scaling, transmission can be divided into multiple blocks, work as overlapping When part is consistent with the power scaling of the part non overlapping, it is only necessary to be limited to inside block.Between block Each intersymbol power scaling scheme be independent of each other.
The division of block can configuration at least one following factor in relation to: DMRS, the configuration of CBG.
It is above-mentioned to may include when the part overlapping is consistent with the power scaling of the part non overlapping Following situations:
All symbols require the power scaling being consistent inside block.
Determine that the part overlapping is with the part non overlapping according to the result that predefined condition judges It is no to use consistent power scaling, for example, above-mentioned condition includes the method in the embodiment of front, such as according to modulation Coding mode, resource ratio, power extraction parameter etc..
When block divides related with the configuration of DMRS, refer to the symbolic number with the position of the DMRS of configuration and DMRS in transmission It measures related.The number of blocks that transmitting can divide is preferably at most the symbol quantity of list symbol DMRS (single-symbol DMRS), The either half of the symbol quantity of double sign DMRS (double-symbol DMRS).The position of DMRS and symbol quantity are common The start-stop position of each block has been determined.
DMRS symbol quantity is related with the configuration of the additional position DMRS (DMRS additional position).Example Such as, for single symbol DMRS, at least one DMRS symbol, when DMRS additional positions are configured with 3, then DMRS mono- shares 4 symbols Number.DMRS symbol quantity is also related with the duration of transmission, such as when the duration of PUSCH being less than or equal to 8 symbols, The configuration for the position for not having DMRS additional.
For example, above-mentioned transmission is divided into several blocks, it is ensured that wherein every block has independent DMRS symbol.If certain area Some or all of symbol is overlapping symbol in block, then is identical power to each symbol of the block scaling.The power scaling mode of each block is independent of each other.
Transmitting terminal and receiving end are consistent the division rule of block.It is illustrated by taking single symbol DMRS as an example below, The DMRS of double sign is also similar, but needs to treat two adjacent-symbols as an entirety.
The mode that block divides can be by the way of predefined fixed partition.I.e. according to the symbolic number of DMRS and position Carry out block division.Block division limits are among neighbouring DMRS symbol.It include surprise among intermediate neighbouring DMRS symbol When several symbols, intermediate symbol is divided into the block of front one or latter one block according to predefined rule.
For example, when the duration of PUSCH is 10 symbols, DMRS is configured altogether to occupy 3 He of symbol there are two symbol When symbol 9, two blocks can be at most divided, the line of demarcation of block is the centre of symbol 3 and symbol 9, and there are 5 symbols in centre, Conventional letter 6 is divided into subsequent block, and 0~symbol of then symbol 5 is the first block, and symbol 6 to symbol 12 is the second block. In following table, although case1 to case4 has different PUSCH symbols, the division limits of block are consistent.
Here is the citing of the PUSCH and DMRS symbol of 10 symbols of duration:
Wherein, symbol 3 and 6 is DMRS symbol, and fixed division mode is exactly that first piece is divided into before symbol 5, symbol Second piece is divided into after numbers 5.
Alternatively, the mode that block divides can be dynamically determined block using scheduled rule according to the start-stop position of transmission It divides.Above-mentioned rule may include the uniform in size or quasi- uniform of block.
It is not integer when transmitting the symbol quantity for including divided by the result of block count, it can be true by the way of prespecified There are several blocks of front 1 more than subsequent block symbolic number, or one few surely.
By taking above-mentioned 10 symbol PUSCH configure 2 DMRS symbols as an example, in following table case1, the segmentation of block 1 and block 2 Point is between symbol 4 and symbol 5, i.e. symbol 0 to 4 is the first block, and symbol 5 to 9 is the second block, in case2,1 He of block The cut-point of block 2 is between symbol 5 and symbol 6, and cut-point is between symbol 7 to 8 in case4.The size of each block It is 5 symbols.
Here is another citing of the PUSCH and DMRS symbol of 10 symbols of duration:
When block divides related with the configuration of CBG, refer to related with the size of the CBG of configuration in transmission and the quantity of CBG. The number of blocks that transmitting can divide is preferably at most the quantity of CBG.
For example, CBG number for including in transmission is 2, then transmission is divided into 2 blocks, by the symbol of actual transmissions Number is divided into two parts.If it is odd number symbols number, intermediate symbol belongs to the block of front or subsequent block depends on The strategy that CBG is divided.For example, the block of front is than subsequent block symbolic number if the CBG of front is bigger than subsequent CBG More 1.
One of the processing of receiving end: receiving end obtains the subframe block mode of transmission in the same way, in the following manner Parse data:
Mode one: receiving end demodulates the data in the block to each subframe block with the DMRS in block.
Mode two: receiving end compares the reception power of the DMRS of each block in the transmission, and difference is exceeded The DMRS symbol of thresholding carries out power compensation, can use the data of multiple all blocks of DMRS joint demodulation later.
Mode three: receiving end compares the reception power of the DMRS of each block in the transmission, and difference is exceeded The DMRS symbol of thresholding carries out power compensation using predefined power scaling numerical value, can be joined later with multiple DMRS Close the data for demodulating all blocks.
Embodiment of above can carry out reasonable combination, be exemplified below, but not as to the disclosure, other may be combined Limitation.
The combination of modulation coding scheme MCS and resource ratio:
Overlapping is part power scaling on demand, and the power of the part Non overlapping is by as follows Mode determine: when ratio be more than thresholding one (corresponding to the first predetermined threshold among the above), and work as above-mentioned transmission tune When coding mode processed is related with amplitude, then non overlapping is also power scaling identical with overlapping. Otherwise, the power of non overlapping is unrelated with the power scaling of overlapping.
When ratio is less than thresholding two (corresponding to the second predetermined threshold among the above), and work as the tune of above-mentioned transmission When coding mode processed is related with amplitude, the power of the part overlapping is zero.
The combination of MCS and block:
Overlapping is part power scaling on demand, and the power of the part Non overlapping is by as follows Mode determine: when the modulation coding scheme of above-mentioned transmission is related with amplitude, then in non overlapping and Also power scaling, non identical with overlapping are in the part that overlapping partly belongs to same block Other parts power in overlapping is unrelated with the power scaling of the part overlapping.
The combination of resource ratio and block:
Overlapping is part power scaling on demand, and the power of the part Non overlapping is by as follows Mode determine: when ratio be more than thresholding one, then partly belong to same block with overlapping in non overlapping Part also do other parts power in power scaling, non overlapping identical with overlapping with The power scaling of the part overlapping is unrelated.Otherwise, the power of non overlapping and overlapping Power scaling is unrelated.
The combination of MCS, resource ratio and block:
Overlapping is part power scaling on demand, and the power of the part Non overlapping is by as follows Mode determines: when ratio is more than thresholding one, and when the modulation coding scheme of above-mentioned transmission is related with amplitude, then and non Also it is power identical with overlapping in the part for partly belonging to same block in overlapping with overlapping Other parts power in scaling, non overlapping is unrelated with the power scaling of the part overlapping. Otherwise, the power of non overlapping is unrelated with the power scaling of overlapping.
When ratio is less than thresholding two, and when the modulation coding scheme of above-mentioned transmission is related with amplitude, The power of the part overlapping is zero.
All implementation methods in the disclosure, after power scaling is in the part overlapping, power When the coefficient of scaling is zero or the transmission power of the part overlapping is 0, the function of the part non overlapping Rate is not influenced by the power scaling of the part overlapping, i.e., the power of the part non overlapping determines only Stand on the power scaling result of the part overlapping.
Specific embodiment 5
To the part for needing to be power scaling, the coefficient of power scaling is selected:
All implementation methods in the disclosure, the power of non overlapping part and the part overlapping Scaling respectively determine when, when being perhaps independently determined or the power in the region non overlapping determine not by When the influence of the power scaling of the part overlapping, the region non overlapping and the region overlapping Power respectively according in respective region power limit or dump power and with other with the time transmission compared with it is preferential Grade is determined.
To the part for needing to be power scaling in above embodiment, power is determined one of as follows The coefficient of scaling.
Mode one: the coefficient of power scaling is determined according to dump power, the priority of transmission.
For example, dump power is distributed to the residue transmission in multiple transmission of the part overlapping, residue transmission is selected The transmission of middle highest priority.If only one transmission of the priority, if dump power meets the transmission function of the transmission Then the transmission does not need to be power scaling rate demand, if dump power is not able to satisfy the transmission power demand of the transmission, Then the dump power all gives the transmission；If the priority there are multiple transmission, if dump power meet it is multiple Then multiple transmission does not need to be power scaling the transmission power demand of transmission, and otherwise it is more not to be able to satisfy this for dump power The transmission power demand of a transmission, then the dump power all gives multiple transmission, the power of multiple transmission above-mentioned at this time The coefficient of scaling is identical, or the coefficient of part of power scaling transmitted is zero, the power of remaining transmission The coefficient of scaling is identical.
Mode two: determine power scaling's according to dump power, the priority of transmission, predefined comparative example Coefficient.The coefficient that the power scaling of transmission is determined according to mode one, is set as PsFactor0, power scaling's Coefficient adjustment is to meet a value of condition in predefined comparative example.Specifically, above-mentioned condition are as follows: be less than or equal to The maximum value of PsFactor0.
For example, power scaling coefficient list: { 1,3/4,1/2,1/4,0 } is determined when according in the above implementation method Power scaling coefficient be 0.8, then according to mode two, the value selected in the list is 3/4.It does so potential Benefit, which is that receiving end is only in need, handles a small amount of several power ratios, reduces complexity.
For the above-mentioned overlapping and non overlapping of the disclosure is generally be directed to two kinds of transmission, work as presence When more than two is transmitted, any two transmission can also be judged and be operated accordingly according to the disclosure above-mentioned mode.? In the presence of more than two transmission, two therein are transmitted, the part overlapping is only with the non-part overlapping For another in two transmission, the non-part overlapping may be exactly when considering more transmission The symbol of overlapping.About priority ranking:
Uplink has following a few classes: PRACH, PUCCH, PUSCH, SRS, in general, the priority transmitted above are as follows: PRACH>PUCCH>PUSCH>SRS。
In the case where carrier wave polymerize (carrier aggregation) scene, there are multiple member carrier (component Carrier, referred to as CC), each CC is also referred to as a serving cell serving cell.One of CC is configured as PCell, as primary cell, the priority than other CC (SCell) is high, and PUCCH is generally configured on PCell.PUSCH The content of PUCCH, such as UCI (uplink control information) can also be carried, including ACK/NACK is (certainly, The response of negative), SR (scheduling request, scheduling request), CSI (channel state information, Channel State Information) etc..In CA scene, the sequence of priority are as follows: PRACH of PCell > PUCCH/PUSCH with ACK/ NACK and/or SR>PUCCH/PUSCH with other UCIs>PUSCH w/o UCI>SRS/PRACH of Scell。
Priority between Long PUCCH, short PUCCH are as follows: short PUCCH > Long PUCCH.
NR needs to guarantee the priority of URLLC, therefore, when there are URLLC business, it is contemplated that following priority is suitable At least one sequence:
The PUSCH of URLLC > other business PUSCH；
The PUCCH of URLLC > other business PUCCH；
The PUSCH of URLLC > other business PUCCH；
The PUSCH of PUCCH > URLLC of URLLC；
Specific embodiment 6
How the coefficient selection of power scaling informs receiving end:
Receiving end can be informed one of in the following manner to power scaling coefficient in above embodiment:
Mode one: power scaling coefficient is carried with the sequence information of DMRS, different sequences represent different coefficients.
Base station is the corresponding relationship that UE is pre-configured with DMRS sequence Yu power scaling coefficient.It needs to be one as UE When power scaling is in transmission, power is determined according to dump power, the priority of transmission, predefined comparative example The coefficient of scaling is set as PsFactor0, is then predefined DMRS sequence institute by the coefficient adjustment of power scaling The maximum value for being less than PsFactor0 can be selected in the power scaling comparative example of expression.Finally, in corresponding transmission The corresponding DMRS sequence of value of the middle power scaling for sending selection.
Above-mentioned corresponding relationship can be fixed corresponding relationship, such as the corresponding power scaling coefficient of sequence 1,2,3,4 List: { 1,3/4,1/2,1/4 }.
Above-mentioned corresponding relationship can also be opposite corresponding relationship, such as the corresponding authorization message of the transmission or scheduling It is 1 that the DMRS sequence determined in information, which represents power scaling coefficient, makes certain change on the basis of the sequence of the DMRS Other power scaling coefficients are represented, such as does the rotation of certain angle and represents other power scaling coefficient.Or Person represents other power scaling numerical value using orthogonal other sequences.
Receiving end needs to demodulate a variety of possible sequence trials one by one.
The interval efficiency that the DMRS sequence of change only influences power scaling.
Mode two: indefinite informing receiving end, but receiving end needs to do alignment processing.
Receiving end will be transmitted and be handled by block, see the associated description of embodiment 4.
When the mode not divided using block, it all regard the entire transmission phase of transmission as a block.
In overlapping or the potential received power in the region overlapping if it is less than predetermined threshold, then determine The transmission power of the part is zero.Otherwise, whole with multiple DMRS joint demodulations after the symbol of multiple DMRS being carried out power compensation The data of a transmission phase.
Specific embodiment 7
Multiple transmission, the extension of multiple parts overlapping:
Many scenes can have multiple transmission transmitted in parallel:
In same BWP, there may be time domain overlapping regions for different channels, signal
Between same CC, different BWP, there may be time domain overlapping regions for different channels, signal
Between CC, there may be time domain overlapping regions for different channels, signal
Dual link even multi-connection scene, is likely to be out of synchronization between different CC, it is understood that there may be partial symbols time domain overlay region Domain
Inside above-mentioned BWP, CC, or between may use different transport parameters for physical layer numerology, cause not Same symbol lengths, therefore even if all in OFDM symbol rank, the minimum transmission of the different transmission of the part overlapping Between unit may also be different.

In time domain overlapping region, it is understood that there may be the minimum unit that sends of multiple transmission, each transmission may be different, it is also possible to It is to be misaligned the time.Such as what is respectively transmitted is that chronomere can be following one: time slot (slot), frame (frame), subframe (subframe), the chronomere that OFDM symbol or system in future use.It should pay attention to the OFDM symbol of different transmission May be different length, it is related with numerology, the corresponding other unit defined with OFDM symbol quantity such as subframe, when Gap may also be different.
The transmission phase (transmission period or transmission duration) of each transmission is with respective Chronomere's description.For example, transmission 1 is the subcarrier spacing of 15kHz, chronomere is used as using OFDM symbol _ 1, transmission 2 is The subcarrier spacing of 60kHz is used as chronomere using OFDM symbol _ 2, and OFDM symbol 1 is 4 times of OFDM symbol _ 2 at this time. If transmission 1 is 4 OFDM symbols (being defaulted as OFDM symbol _ 1), transmission 2 be 4 OFDM symbols (be defaulted as OFDM symbol _ 2), then the transmission phase length of transmission 1 and transmission 2 is different.
The above-mentioned method of the disclosure for a transmission in overlapping, determine the part its overlapping and The power of the part non overlapping.The division of overlapping and non overlapping is also with corresponding transmission Chronomere subject to.It combines section in different times when a transmission is transmitted with different other there are overlapping, i.e., The entire transmission phase overlapping of the transmission is partially larger than 1, then handles power one by one to each part overlapping Scaling obtains the power scaling coefficient of each part overlapping, needs when the periods multiple and different in the transmission phase When unifying power scaling, then using the smallest value in the power scaling coefficient of each part overlapping.
As shown in fig. 6, the transmission phase of PUSCH is OFDM symbol 1 to 9, this portion Chong Die with PRACH in preceding 3 OFDM symbols Divide and be known as overlapping1, Chong Die with PUCCH in rear 4 symbols, this part is known as overlapping2, intermediate 2 symbols For Non-overlapping Domain.If the power scaling coefficient of overlapping1 is the power of 0.9, overlapping2 Scaling coefficient be 0.8, and according to the disclosure or other methods determine multiple and different times in the transmission phase of the PUSCH When section needs unified power scaling, then the power scaling coefficient of overlapping1 and overlapping2 is used In the smallest value, i.e., 0.8, as unified power scaling value.
Through the above description of the embodiments, those skilled in the art can be understood that according to above-mentioned implementation The method of example can be realized by means of software and necessary general hardware platform, naturally it is also possible to by hardware, but it is very much In the case of the former be more preferably embodiment.Based on this understanding, the technical solution of the disclosure is substantially in other words to existing The part that technology contributes can be embodied in the form of software products, which is stored in a storage In medium (such as ROM/RAM, magnetic disk, CD), including some instructions are used so that a terminal device (can be mobile phone, calculate Machine, server or network equipment etc.) execute method described in each embodiment of the disclosure.
