Description

Transmission power determining method and device and transmission demodulation method and device

Technical Field

The present disclosure relates to the field of communications, and in particular, to a method and an apparatus for determining power of transmission, and a method and an apparatus for demodulating transmission.

Background

At present, a New Radio (NR) technology as a fifth generation mobile communication system needs to support different types of application scenarios and also needs to support a conventional frequency band, a New high frequency band, and a beam mode, which brings a great challenge to a power control technology.

The power control technique includes not only how to determine the transmission power of a single channel/signal, but also how to share power among multiple channels and signals when the multiple channels and signals are transmitted in parallel. Especially, under the condition of insufficient power, how to distribute power among a plurality of channels and signals ensures that the maximum power limit cannot be exceeded at any time.

In Long Term Evolution (LTE), data is coded and decoded in units of subframes, and uplink transmission is also scheduled in units of subframes. At least in the synchronized multi-carrier aggregation technique, the overlapping time of concurrent transmission among multiple channels is in units of subframes, which coincide with the time units of coding and decoding. In NR, the uplink channel and signal can be configured with flexible start and end positions, and the start and end positions indicate that a smaller time unit is used, such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol. Therefore, the overlapping part of multiple transmissions may last for several OFDM symbols, and the length of the data to be coded and decoded is all or part of the length of the transmission itself, so the length of the overlapping part is not consistent with the length of the coded and decoded part. Such inconsistencies may cause the following problems: when the overlapped part has insufficient power, certain criteria are used to determine that some transmissions need to be transmitted with reduced power, but only the overlapped part of the transmissions needs to be transmitted with reduced power, and the non-overlapped part does not need to be reduced from the viewpoint of maximum power limitation, which may result in power imbalance between the overlapped part (corresponding to the time domain overlapping region) and the non-overlapped part (corresponding to the non-time domain overlapping region). That is, there is a problem in the prior art that the transmitted power of the overlapped part and the non-overlapped part is not balanced.

In view of the above problems, no effective solution has been proposed in the related art.

In an optional embodiment, when the information includes a modulation and coding scheme and a power reduction parameter of the transmission, determining power of a time-domain overlapping region and a non-time-domain overlapping region of the transmission according to the information includes at least one of: when the power reduction parameter is larger than a seventh preset threshold value and the transmitted modulation coding mode meets a preset condition, carrying out the same power reduction on part or all of the transmitted non-time domain overlapping regions; when the power reduction parameter is less than or equal to the eighth preset threshold value and the transmitted modulation coding mode meets the preset condition, the power of the transmitted time domain overlapping region is zero; wherein the seventh predetermined threshold is greater than or equal to the eighth predetermined threshold. In this embodiment, the seventh predetermined threshold and the eighth predetermined threshold have the same meaning as the first predetermined threshold and the second predetermined threshold, respectively.

In an alternative embodiment, the preset condition includes at least one of: the modulation coding mode is larger than a preset threshold, the modulation coding mode is related to amplitude, the bit number carried by the modulation symbol corresponding to the modulation coding mode is larger than a preset value, and the modulated symbol corresponding to the modulation coding mode is in a non-constant modulus.

In an optional embodiment, determining the power of the time domain overlapping region and the non-time domain overlapping region of the transmission includes: after power reduction of the transmitted time-domain overlap region, the power adjustment of the transmitted non-time-domain overlap region is independent of the power determination of the transmitted time-domain overlap region if one of the following conditions is satisfied: the power reduction coefficient is zero and the power of the time domain overlapping region of the transmission is zero. In this embodiment, the power adjustment of the non-time domain overlapping region is independent of the power adjustment of the time domain overlapping region, that is, the power adjustments of the two regions do not affect each other, so that the performance of the whole transmission can be improved.

In an alternative embodiment, the power of the time domain overlapping region and/or the non-time domain overlapping region of the transmission is adjusted by: the ratio of the power of the transmitted time domain overlapping region and the non-time domain overlapping region to the required power of the transmission is respectively used as the power reduction coefficient of the transmitted time domain overlapping region and the non-time domain overlapping region to be adjusted; determining the adjusted power reduction coefficients of the time domain overlapping region and the non-time domain overlapping region of the transmission by the following method for the power reduction coefficients of the time domain overlapping region and the non-time domain overlapping region of the transmission to be adjusted respectively: selecting a preset value from a preset list as an adjusted power reduction coefficient, wherein the preset value is less than or equal to the maximum value of numerical values in the power reduction coefficient to be adjusted; and adjusting the power of the time domain overlapping region and/or the non-time domain overlapping region of the transmission according to the adjusted power reduction coefficient of the time domain overlapping region and the non-time domain overlapping region of the transmission. In this embodiment, the power scaling coefficient is determined according to the remaining power, the priority of transmission, and a predefined value list. Namely, the transmitted power scaling coefficient is determined to be PsFactor0 according to the above, and the power scaling coefficient is adjusted to be a value satisfying the condition in the predefined value list. Specifically, the above conditions are: less than or equal to the maximum value of PsFactor 0. For example, power scaling coefficient list: {1,3/4,1/2,1/4,0}, when the power scaling factor determined according to the above implementation is 0.8, then according to mode two, the value selected in the list is 3/4. This has the potential benefit that the receiver only needs to handle a few power ratios, reducing complexity. Before adjusting the power reduction coefficient, the remaining power after power reduction of transmission needs to be determined, and the power reduction coefficient is determined according to the priority of transmission of the sum of the remaining power. And distributing the residual power to the residual transmission in the multiple transmissions of the overlapping part, and selecting the transmission with the highest priority in the residual transmissions. If the priority has only one transmission, the transmission does not need power scaling if the remaining power meets the transmission power requirement of the transmission, and if the remaining power cannot meet the transmission power requirement of the transmission, the remaining power is completely distributed to the transmission; if the priority has a plurality of transmissions, the plurality of transmissions do not need to be power-scaled if the remaining power meets the sending power requirements of the plurality of transmissions, otherwise, the remaining power cannot meet the sending power requirements of the plurality of transmissions, the remaining power is all distributed to the plurality of transmissions, and at this time, the coefficients of the power-scaled of the plurality of transmissions are the same, or the coefficients of the power-scaled of the partial transmissions are zero, and the coefficients of the power-scaled of the remaining transmissions are the same.

In an alternative embodiment, the demodulation reference signal DMRS sequence is determined by: and determining the DMRS sequence according to a predetermined relation, wherein the information of the DMRS sequence corresponds to the power reduction coefficient. In this embodiment, the DMRS sequence is transmitted to the base station, and the base station determines the power reduction coefficient based on the correspondence between the DMRS sequence and the power reduction coefficient.

In an optional embodiment, before determining the power of the time domain overlapping region and/or the non-time domain overlapping region of the transmission, the method further includes: determining a plurality of time domain overlapping regions in a preset transmission period; the minimum value of each power reduction coefficient is selected from the power reduction coefficients of each time domain overlapping region as the power reduction coefficient for the time domain overlapping region and/or the non-time domain overlapping region of the transmission.

In the present embodiment, a method for dividing a transmission is provided, and fig. 3 is a flowchart of a method for dividing a transmission according to an embodiment of the present disclosure, where as shown in fig. 3, the flowchart includes the following steps:

step S302, block division is carried out on transmission;

step S304, determining power reduction coefficients for transmission in each block, respectively.

Through the steps, the transmission is divided into blocks before the power adjustment of the transmission is carried out by the sending end, and the power reduction coefficient is respectively determined for the transmission in each block, so that the block management can be carried out on the transmission, and the efficiency of carrying out the power adjustment on the transmission is improved.

In an alternative embodiment, the block partitioning the transmission comprises: and partitioning the transmission according to the configuration of the demodulation reference signal DMRS and/or the configuration of the coding block group CBG. In this embodiment, the number and location of DMRS symbols in transmission may be varied

In the present embodiment, a method for determining power of transmission is provided, and fig. 4 is a flowchart of a method for determining power of transmission according to an embodiment of the present disclosure, as shown in fig. 4, the flowchart includes the following steps:

step S402, sending scheduling information to a sending end, where the scheduling information is used to instruct the sending end to determine at least one of the following information: the modulation coding mode of transmission, the resource proportion, the power reduction parameter, the priority of the transmission and the indication that the sending end utilizes at least one of the above information to determine the power of the time domain overlapping region and/or the non-time domain overlapping region of the transmission when the sum of the transmission power of the time domain overlapping region is smaller than the preset power;

step S404, receiving the transmission with the power determined according to the information sent by the sending end, and demodulating the transmission.

Through the steps, as the receiving end sends the scheduling information to the terminal, the terminal can determine the information such as the modulation coding mode, the resource proportion, the power reduction parameter, the transmission priority and the like of the transmission according to the scheduling information. And when the sum of the transmitted powers of the time domain overlapping regions is smaller than the preset power, the terminal determines the power of the transmitted time domain overlapping regions and/or non-time domain overlapping regions by using the determined information. The power-adjusted transmission is then sent to the receiving end, which demodulates the transmission. Therefore, the problem of power imbalance between the time domain overlapping region and the non-time domain overlapping region in the related technology can be solved, and the effects of flexibly adjusting the transmission power, improving the power efficiency of the whole transmission and being beneficial to data demodulation are achieved.

Alternatively, the main body of the above steps may be a base station, etc., but is not limited thereto.

In an optional embodiment, after receiving the transmission with the power determined according to the information sent by the sending end, the method further includes: the transmission is block partitioned.

In an alternative embodiment, demodulating the transmission includes one of: respectively demodulating the data in each block by using the DMRS in each block; comparing the received power of the DMRS in each block, performing power compensation on the DMRS of which the result is greater than a first preset value, and demodulating the transmission in each block by using the DMRS of which the power is compensated in each block; comparing the received power of the DMRS of the demodulation reference signals of each block to obtain the DMRS of which the comparison result is larger than a second preset value, performing power compensation on the received power of the DMRS by using preset power reduction values, and demodulating the transmission in each block by using the DMRS of each block after power compensation.

The present disclosure is described in detail below with reference to specific examples:

when the UE transmits uplink transmission, it needs to occupy a certain transmit power, which cannot exceed the limit of maximum power. For a plurality of transmissions (transmission) whose number is greater than 1, when there is an overlap in time, it is necessary to satisfy a condition that the sum of the powers of the plurality of transmissions is not greater than the maximum power. Overlapping in time may refer to multiple transmissions sharing all or part of a period of time, including but not limited to the following multiplexing schemes: frequency Division Multiplexing (FDM), Code Division Multiplexing (CDM), Space Division Multiplexing (SDM). The transmission refers to occupying a specific channel resource to transmit corresponding information, for example, 4 OFDM symbols (hereinafter also referred to as symbols for short, which indicate a period of time) of the PUSCH are occupied for transmitting a data packet, and the PUSCH with the 4 symbols is referred to as a PUSCH transmission. Similarly, there is also transmission of PUCCH, transmission of SRS, transmission of PRACH. There may also be transmission of long PUCCH, transmission of short PUCCH, transmission of long PUSCH, transmission of short PUSCH. There may also be different classes of SRS transmissions.

The multiple transmission overlap portion, if exceeding the maximum transmit power limit, guarantees the transmit power of the high priority transmission in a predefined priority first, and performs power scaling on the low priority transmission.

As shown in fig. 5, transmission of PUSCH occupies OFDM symbols #1 to #9, and transmission of PUCCH occupies OFDM symbols #6 to #10. Considering only these two transmissions, for PUSCH transmission, overlapping parts are symbols #6 to #9, non overlapping parts are #1 to #5, for PUCCH transmission, overlapping parts are symbols #6 to #9, non overlapping parts are #10, transmission power required for PUSCH is P1, transmission power required for PUCCH is P2, and the sum of the two powers P1+ P2 exceeds the maximum transmission power limit P _ max of the UE. Assuming that the transmission priority of the PUCCH is higher than that of the PUSCH, the transmission power of the UE meets the power of the PUCCH preferentially, and the maximum transmission power of the PUSCH transmission in the overlapping part can only be P _ max-P2, which is less than the power P1 required for transmission. For the non overlapping part of the PUSCH, it is better to keep the power consistent during the whole transmission period of the PUSCH from the convenience of receiving the PUSCH from the receiving end, i.e. the same power scaling as that used for the overlapping part is required.

Power scaling is also referred to as Power reduction, or Power adjustment, or Power reduction. The ratio of the adjusted power to the original power is called power scaling coefficient, or power adjustment coefficient, power reduction coefficient. The power-scaling transmission power of the overlapping part of the PUSCH is P _ max-P2, and the power-scaling coefficient is (P _ max-P2)/P1.

Although this processing method is simple, the power efficiency is not high, and performing power reduction on the non-overlapping part (non-overlapping part) according to the requirement of the overlapping part (overlapping part) may cause power reduction of the non-overlapping part, and the demodulation performance is affected, especially for the case that the non-overlapping part occupies a small proportion of the transmission period. In addition, this processing method is also disadvantageous for the stationarity of a Power Amplifier (PA) because the power of the non overlapping portion is reduced, so that the inter-symbol and power differences become large.

Aiming at the problem that the receiving end is difficult to process and even can not demodulate due to the fact that the power of the overlapped part and the non-overlapped part is unbalanced; if the non-overlapping part adopts the same power reduction mode as the overlapping part, the problem of reduction of the power efficiency of the part is caused; the embodiment adopts the following technical scheme:

firstly, judging the time domain overlapping condition of transmission, then when the power of the time domain overlapping part is insufficient, namely at least one transmission needs to be subjected to power reduction, namely the power reduction coefficient is less than 1, judging whether the power reduction mode of the time domain overlapping part of the transmission is the same as that of the other part of the transmission or not, or judging whether the power reduction coefficient of the time domain overlapping part of the transmission is applied to the other part of the transmission or not. The method comprises the following specific steps:

the first condition is as follows: whether the transmission with more than 1 number has overlapping in time domain can be predicted, that is, whether overlapping exists in a slot can be determined at least at the beginning of the slot, including whether there is URLLC service (Ultra Reliable Low Latency communication);

case two: whether overlapping exists is bursty, i.e., whether time-domain overlap will occur cannot be predicted. Within a predefined transmission time, an overlapping portion (corresponding to the time domain overlapping region in the above) and a non-overlapping portion (corresponding to the non-time domain overlapping region in the above) are determined.

When multiple transmissions have time domain overlap (overlap, or time domain overlap, or overlap), the length of the time domain overlap region is in symbol units. In particular, when the symbol lengths used for a plurality of transmissions may be different, the symbol length is in units of the respective transmission itself.

For a certain transmission, the method for determining whether each part in the transmission period belongs to the time domain overlapping region is as follows:

the time domain overlapping portion of a transmission (assumed to be transmission two (corresponding to the second transmission in the above) with a higher priority than the above transmission (assumed to be transmission one (corresponding to the first transmission in the above)) is referred to as the time domain overlapping region of the transmission (transmission one) with the corresponding transmission (transmission two).

The above assumes that transmission two has higher priority than transmission one, so for transmission two, the time domain overlap with transmission one is not counted as a time domain overlap region.

For a transmission (say transmission one), there are multiple transmissions (say transmission two, transmission three) that have a higher priority than it, and for transmission one, the time domain overlap region may comprise multiple time domain overlap regions based on a time domain overlap combination with different transmissions. For example, the time domain overlapping portions of transmission one, transmission two, and transmission three are further divided into: the time domain overlapping region of transmission one and transmission two, the time domain overlapping region of transmission one and transmission three, the time domain overlapping region of transmission one and transmission two and transmission three.

The other parts of the transmission except the time domain overlapping area are non-time domain overlapping areas.

Examples are as follows: there are 3 transmissions, transmission 1, transmission 2, transmission 3, with priority going from high to low.

Transmission 1:

occupation symbols

0, 1, 2

And (3) transmission 2:

occupation symbols

2, 3, 4, 5

And (3) transmission:

occupation symbols

0, 1, 2, 3, 4, 5, 6, 7, 8

Transmission 1 has the highest priority, and all symbols belong to a non-time domain overlapping region;

transmission 2 is the second priority, and the overlapping situation between transmission 1 with higher priority than itself and its own time domain needs to be considered, for example, symbol 2 is a time domain overlapping region, and

symbols

3, 4, and 5 are non-time domain overlapping regions;

transmission 3 is a third priority, the time domain overlap of transmission 3 with transmission 1 is symbols 0, 1, the time domain overlap region of transmission 3 with transmission 2 is

symbols

3, 4, 5, the time domain overlap region of transmission 3 with transmission 1 and transmission 2 is symbol 2, and

symbols

6, 7, 8 are non-time domain overlap regions.

When a transmission has multiple time domain overlap regions, each time domain overlap region determines the power of the transmission. Specifically, the power of the transmission is determined according to the required power of the transmission, the required power of all transmissions in the time domain overlapping region with higher priority than the transmission, and the maximum allowed power of the time domain overlapping region. That is, the maximum allowed power is subtracted by the required power of all transmissions in the time domain overlapping region, which are higher than the priority of the transmission, to obtain the maximum allowed power of the transmission. The power to which the transmission can be divided is derived from the required power for the transmission and the maximum power allowed for the transmission. That is, the power into which the transmission can be divided is the smaller of the maximum power allowed for transmission and the required power for transmission.

When the processing is performed on a certain time domain overlapping region of a certain transmission, if the transmission with the same priority as the transmission exists in the transmission region, the power of the transmission is determined according to the required power of the transmission, the required power of all other transmissions with the same priority as the transmission, the required power of all transmissions with higher priority than the transmission in the time domain overlapping region, and the maximum allowed power of the time domain overlapping region. That is, the maximum allowable power is subtracted from the required power of all transmissions having a higher priority than the transmission in the time domain overlapping region, thereby obtaining the maximum allowable power of all transmissions having a priority equal to the transmission. The power to which the transmission can be divided is derived from the sum of the required powers for all transmissions of equal priority to the transmission and the maximum power allowed for all transmissions of equal priority to the transmission. That is, the sum of the power that all transmissions of the same priority as the above transmissions can be divided into is: the smaller of the sum of the required powers for all transmissions of equal priority to the transmission and the maximum power allowed for all transmissions of equal priority to the transmission.

When the sum of the power that can be divided by all transmissions with the same priority as the transmission is less than the sum of the required power of all transmissions with the same priority as the transmission, all or part of the transmissions with the same priority as the transmission need to be power-reduced in equal proportion. If the power of part of the transmission with the same priority as the transmission is reduced proportionally, the power of other transmissions with the same priority as the transmission is zero.

When a certain transmission has multiple time domain overlapping regions, the power of the transmission is determined for each time domain overlapping region according to the above manner.

The power is also determined for non-time domain overlapping regions. Specifically, the power of the non-time domain overlapping region is: the lesser of the area maximum allowed power and the required power for the transmission.

The maximum allowed power may be defined in a certain frequency domain range, such as at least one of BWP level, CC level, and UE level. When multiple levels are defined, the multiple transmissions need to meet at each level that the sum of the power of the multiple transmissions within the frequency domain region does not exceed the maximum allowed power defined for that frequency domain region. For example, when multiple transmissions belong to one BWP (bandwidth partial), the maximum allowed power may be the maximum allowed power of the corresponding BWP; when a plurality of transmissions belong to one CC, the maximum allowed power is the maximum allowed power of the CC; when multiple transmissions belong to multiple CCs, the maximum allowed power is the maximum allowed power of the multiple CCs, possibly the maximum allowed power of the UE.

The determination of whether to perform consistent power reduction for a plurality of time-domain overlapping regions and non-time-domain overlapping regions is similar to the manner of performing consistent power reduction for the time-domain overlapping regions and the non-time-domain overlapping regions described above. That is, the power of the transmission of the time-domain overlapping region and/or the non-time-domain overlapping region is determined based on at least one of the following information: modulation coding mode of transmission, resource proportion, power reduction parameter and priority of transmission.

There may be multiple time domain overlapping regions, and in this case, the resource ratio refers to a ratio of the time domain overlapping region to the entire transmission duration.

And judging whether the overlapping areas and other parts of the transmission adopt a consistent power reduction mode one by one for the multiple time domain overlapping areas. If any one of the time domain overlapping regions requires a power reduction method consistent with that of the other part of the transmission, all the time domain overlapping regions need to adopt a power reduction method consistent with that of the non-overlapping region. In this case, the value at which the power reduction coefficient is the smallest in the plurality of time domain overlapping regions is taken as the uniform power reduction coefficient.

For a certain transmission, if a blocking mode is adopted and a consistent power reduction mode may be maintained inside each block, the range of the transmission refers to one or more time domain overlapping regions and non-time domain overlapping regions inside the block. The power determination is independent between the blocks.

The range of the above power reduction in the time domain may be one of the following:

the whole transmission is carried out;

respective time domain overlap regions of transmission;

a non-time domain overlapping region of transmission;

each block of the transmission;

within each block of transmission, each time domain overlap region;

within each block of transmission, there is no time domain overlap region.

The above-described embodiments are described in detail with reference to several specific examples.

Detailed description of the preferred embodiment 1

For a transmission, determining a required power for the transmission based on at least one of: open loop power control parameters, closed loop power control parameters, path loss PL configuration parameters, factors for path loss PL.

The method includes determining a time-domain overlap region and a non-time-domain overlap region during its transmission, and determining powers of the time-domain overlap region and the non-time-domain overlap region of the transmission.

The above time domain overlap region may comprise a plurality of different time domain overlap regions, respectively corresponding to the simultaneous transmission of the transmission in time domains combined with other different transmissions.

When the transmission needs to be power-reduced in one or more time domain overlapping regions, that is, when the power reduction coefficient in the time domain overlapping region is smaller than a preset threshold, for example, 1, the power of the time domain overlapping region and/or the non-time domain overlapping region is adjusted according to the modulation coding mode. The adjusting method comprises the following steps:

when the modulation and coding scheme of the transmission meets the preset condition, the power reduction factor of the time domain overlapping region is the same as the power reduction factor of the region outside the time domain overlapping region of the transmission, that is, the power reduction factor of the time domain overlapping region is adopted by other regions for power reduction.

When the modulation coding mode of the transmission does not satisfy the preset condition, the power reduction factor of the time domain overlapping region is not used for the power of the region outside the time domain overlapping region of the transmission, namely, whether the other regions carry out power reduction or not and how the adopted power factor is determined to be not influenced by the power reduction mode or the power reduction factor of the time domain overlapping region when power reduction is carried out.

The preset condition includes at least one of: the modulation coding mode is larger than a preset threshold; the modulation coding mode is amplitude dependent; the number of bits carried by a modulation symbol is greater than a predetermined value, e.g., 2; the modulated symbols corresponding to the modulation coding scheme are non-constant modulus.

The modulation coding method independent of the amplitude means that the signal points in the constellation diagram are distinguished by factors other than the amplitude, such as BPSK (binary phase shift keying), QPSK (quadrature phase shift keying), pi/2 QPSK (pi/2 quadrature phase shift keying), DBPSK (differential BPSK), and the like; the Modulation and coding scheme related to the Amplitude refers to factors that depend on the distinction of signal points in the constellation diagram, including the Amplitude, for example, 16QAM (16Quadrature Amplitude Modulation), 64QAM, 256QAM, 1024QAM, and the like.

The modulation and coding scheme is greater than a predetermined threshold, the predetermined threshold is a modulation and coding scheme, for example, QPSK, and the modulation and coding scheme greater than the predetermined threshold includes at least one of: 16QAM, 64QAM, 256QAM, 1024 QAM; the modulation coding mode not greater than the predetermined threshold includes at least one of: BPSK, QPSK, π/2QPSK, DBPSK.

Specific example 2

The UE adjusts the modulation and coding mode:

and when the transmitted original modulation coding mode meets the preset condition, modifying the modulation coding mode of the time domain overlapping region into a target modulation coding mode irrelevant to the amplitude. And respectively determining the power reduction modes of the time domain overlapping region and the non-time domain overlapping region.

The target modulation coding scheme independent of the amplitude may be a predefined modulation coding scheme, such as Quadrature Phase Shift Keying (QPSK), and the original modulation coding scheme is modified to a predetermined target modulation coding scheme. Or the target modulation and coding scheme unrelated to the amplitude may be multiple predefined modulation and coding schemes, such as QPSK and BPSK, and the mapping relationship between the original modulation and coding scheme and the target modulation and coding scheme is configured by the base station through a message or predefined. If the original Modulation and coding scheme is 256QAM (Quadrature Amplitude Modulation) or 128QAM, the corresponding target Modulation and coding scheme is QPSK, the original Modulation and coding scheme is 64QAM or 16QAM, and the corresponding target Modulation and coding scheme is BPSK.

Or when the transmitted original modulation coding mode meets the preset condition, modifying the modulation coding modes of the time domain overlapping region and the non-time domain overlapping region into a target modulation coding mode irrelevant to the amplitude.

The preset condition comprises at least one of the following conditions: the modulation coding mode is larger than a preset threshold; the modulation coding mode is amplitude dependent; the number of bits carried by a modulation symbol is greater than a predetermined value, e.g., 2; the modulated symbols corresponding to the modulation coding scheme are non-constant modulus.

After the UE modifies the modulation and coding scheme, the UE needs to notify the base station in one of the following ways:

the sending end sends the modified modulation coding mode information to the receiving end;

the sending end indicates whether the modulation coding mode is modified or not by using 1-bit information;

the sending end indicates whether the modulation coding mode is modified or not in an implicit mode; implicit ways may include: indicated with DMRS sequences. Specifically, if the UE uses the DMRS sequence configured by the base station, it indicates that the modulation and coding scheme is not modified, and the UE uses the modulation and coding scheme configured by the base station; and if the UE uses the DMRS sequences except the DMRS sequences configured by the base station, the UE indicates that the modulation coding mode is modified. For example, the configured DMRS sequence is multiplied by a coefficient, or another base station pre-configured DMRS sequence is used.

The receiving end, namely the base station receives one of the above information, judges whether the transmitting end, namely the UE, modifies the modulation coding mode, if so, the modified modulation coding mode is obtained according to the preset relation for receiving and demodulating.

The sending UE may not inform the base station whether the modulation and coding scheme is modified through the above scheme, and the receiving end, i.e. the base station, may assume that both cases are possible. The base station firstly demodulates by using the configured modulation coding mode, if the demodulation is wrong, the sending end is supposed to modify the modulation coding mode, and the demodulation is carried out by using the modified modulation coding mode.

If the transmitting end modifies the modulation coding mode, the PHR (power head room report) is triggered to report.

Or, the sender modifies the modulation and coding scheme, which is one of the conditions for triggering phr (power head report). The sending end modifies the modulation coding mode to be possibly used as a complete trigger condition reported by the PHR and also to be possibly used as a partial trigger condition reported by the PHR. The meaning of a partial trigger condition is that it needs to be combined with other conditions as a condition to trigger PHR.

Specific example 3

When the transmission needs to be power-reduced in one or more time domain overlapping regions, that is, when the power reduction coefficient in the time domain overlapping region is smaller than a preset threshold, for example, 1, the power of the time domain overlapping region and/or the non-time domain overlapping region is adjusted according to the resource proportion. The adjusting method comprises the following steps:

if the time length proportion of the time domain overlapping region to the non-time domain overlapping region or the time length proportion of the time domain overlapping region to the time length of the whole transmission period of the transmission exceeds a preset threshold one, power reduction is carried out on the non-time domain overlapping region and the time domain overlapping region in the same mode; otherwise, the non-time domain overlapping region is independent of the power reduction mode of the time domain overlapping region.

And if the time length proportion of the time domain overlapping region to the non-time domain overlapping region or the time length proportion of the time domain overlapping region to the whole transmission period of the transmission does not exceed the preset threshold two, the power of the time domain overlapping region is zero.

The first predetermined threshold and the second predetermined threshold may be the same, or the first predetermined threshold may be greater than the second predetermined threshold.

For example, in fig. 5, for PUSCH transmission, the transmission period is 9 symbols, the overlapping length is 4 symbols, if the above predetermined threshold is the ratio of the overlapping duration to the entire transmission period of the transmission, and the threshold one is set to 1/3, then 4/9>1/3, the power of PUSCH in overlapping part is P _ max-P2, and the power of non overlapping part is also P _ max-P2. If overlapping is only 1 symbol long, 1/9<1/3, 8 symbols of PUSCH in non overlapping part do not need to be power scaling the same as 1 overlapping symbol. If the second threshold is set to 1/9, the ratio of the overlapping duration to the whole transmission period of the transmission does not exceed the second threshold, and the transmission power of 1 symbol in the overlapping part is zero.

If the power reduction coefficient of the time domain overlapping region or the power of the time domain overlapping region after power reduction exceeds a preset threshold three, performing power reduction in the same way on the non-time domain overlapping region and the time domain overlapping region; otherwise, the non-time domain overlapping region is independent of the power reduction mode of the time domain overlapping region.

And if the power reduction coefficient of the time domain overlapping region or the power of the time domain overlapping region after power reduction does not exceed the preset threshold four, the power of the time domain overlapping region is zero.

The predetermined threshold three and the predetermined threshold four may be the same, or the predetermined threshold three is greater than the predetermined threshold four.

The above resource ratio may be applied in combination with a power reduction coefficient or a transmission power after power reduction. For example, the following determination process may be independently effective.

The overlapping part performs power scaling as required, if the proportion of the time length of overlapping to the time length of non overlapping or the proportion of the time length of overlapping to the whole transmission period of the transmission exceeds a preset threshold one, and if the coefficient of the power scaling or the transmission power after the power scaling exceeds a preset threshold three, the non overlapping also performs power scaling which is the same as the overlapping; otherwise, the power of non overlapping part is not related to power scaling of overlapping part.

The overlapping part performs power scaling as required, if the proportion of the time length of overlapping to the time length of non overlapping, or the proportion of the time length of overlapping to the whole transmission period of the transmission exceeds a preset threshold one, or if the coefficient of power scaling, or the sending power after power scaling exceeds a preset threshold three, non overlapping also performs power scaling which is the same as overlapping; otherwise, the power of non overlapping part is not related to power scaling of overlapping part.

And if the ratio of the overlapping time length to the non overlapping time length or the ratio of the overlapping time length to the whole transmission period of the transmission does not exceed a preset threshold two, and if the coefficient of the power scaling or the transmission power after the power scaling does not exceed a preset threshold four, the transmission power of the overlapping part is zero.

And if the ratio of the overlapping time length to the non overlapping time length, or the ratio of the overlapping time length to the whole transmission period of the transmission does not exceed a preset threshold two, or if the coefficient of power scaling, or the transmission power after power scaling does not exceed a preset threshold four, the transmission power of the overlapping part is zero.

Specific example 4

Partitioning according to the position of the DMRS, and performing power scaling according to the partitions;

in order to reduce the impact range of power scaling, the transmission can be divided into a plurality of blocks, and when the overlapping part is consistent with the power scaling of the non overlapping part, only the blocks need to be limited inside. The inter-symbol power scaling schemes between blocks are independent of each other.

The partitioning of the block may be related to at least one of the following factors: configuration of DMRS, configuration of CBG.

The above-mentioned when the overlap part coincides with the power scaling of the non overlap part may include the following cases:

all symbols inside a block need to maintain a consistent power scaling.

Whether the overlapping part and the non overlapping part adopt consistent power scaling is determined according to the result of the judgment of a predefined condition, for example, the condition comprises the method in the previous embodiment, for example, according to the modulation coding mode, the resource proportion, the power reduction parameter and the like.

When the block division is related to the arrangement of the DMRSs, the block division refers to the position of the DMRSs arranged in the transmission and the number of symbols of the DMRSs. The number of blocks into which a transmission can be divided is at most the number of symbols for a single-symbol DMRS (single-symbol DMRS) or half the number of symbols for a dual-symbol DMRS (double-symbol DMRS). The position of DMRS and the number of symbols together determine the start-stop position of each block.

The number of DMRS symbols is related to the configuration of DMRS additional positions (DMRS additional positions). For example, for a single-symbol DMRS, there is at least one DMRS symbol, and when 3 DMRS extra positions are configured, there are 4 DMRS symbols in total. The number of DMRS symbols also relates to the duration of the transmission, e.g., when the duration of PUSCH is less than or equal to 8 symbols, there is no configuration of additional locations for DMRS.

For example, the transmission is divided into several blocks, ensuring that each block has a separate DMRS symbol. If part or all of the symbols in a block are overlapping symbols, then the same power scaling is done for each symbol in the block. The power scaling modes of the blocks are independent of each other.

The partition rules of the blocks by the sending end and the receiving end are consistent. In the following, a single-symbol DMRS is taken as an example, and dual-symbol DMRSs are similar, but two adjacent symbols need to be considered as a whole.

The block division mode can adopt a predefined fixed division mode. Namely, the block division is performed according to the number of symbols and the position of the DMRS. The block partition boundary is in between adjacent DMRS symbols. When the middle adjacent DMRS symbol includes an odd number of symbols in the middle, the middle symbols are divided into a previous block or a next block according to a predefined rule.

For example, when the PUSCH has a duration of 10 symbols, the DMRS is configured to have a total of two symbols, and occupy symbol 3 and symbol 9, at most two blocks may be divided, where the boundary of the blocks is the middle of symbol 3 and symbol 9, and there are 5 symbols in the middle, and assuming that symbol 6 is divided into following blocks, symbols 0 to 5 are the first blocks, and symbols 6 to 12 are the second blocks. As shown in the table below, although there are different PUSCH symbols in the cases 1 to 4, the partition boundaries of the tiles are consistent.

The following are examples of PUSCH and DMRS symbols of duration 10 symbols:

the

symbols

3 and 6 are DMRS symbols, and the fixed division manner is to divide the DMRS symbols into a first block before the symbol 5 and a second block after the symbol 5.

Or, the partition of the block may be dynamically determined by a predetermined rule according to the start-stop position of the transmission. The rules may include that the size of the blocks is uniform or quasi-uniform.

When the number of symbols included in a transmission divided by the number of blocks is not an integer, it can be determined in a predetermined manner whether the number of preceding blocks is 1 more or one less than the number of symbols of the following blocks.

Taking the above example of configuring 2 DMRS symbols for 10-symbol PUSCH, in table case1 below, the partition points of tile 1 and tile 2 are between symbol 4 and symbol 5, i.e., symbols 0 to 4 are the first tile, symbols 5 to 9 are the second tile, in case2, the partition points of tile 1 and tile 2 are between symbol 5 and symbol 6, and the partition points in case4 are between

symbol

7 and 8. The size of each block is 5 symbols.

The following is another example of PUSCH and DMRS symbols of duration 10 symbols:

when the block partition is related to the CBG allocation, it refers to the size of the CBG allocated in the transmission and the number of CBGs. The number of blocks that a transmission can divide is at most the number of CBGs.

For example, if the number of CBGs included in a transmission is 2, the transmission is divided into 2 blocks and divided into two parts according to the number of symbols actually transmitted. If the number of the odd symbols is the number, whether the middle symbol belongs to the previous block or the following block depends on the strategy of CBG division. For example, if the preceding CBG is larger than the following CBG, the preceding block has 1 more symbols than the following block.

And (3) processing at a receiving end: the receiving end obtains the transmitted subframe block mode in the same way, and analyzes the data according to one of the following modes:

the first method is as follows: the receiving end demodulates data in each subframe block by using the DMRS in the block.

The second method comprises the following steps: the receiving end compares the receiving power of the DMRS of each block in the transmission, performs power compensation on the DMRS symbols with the difference exceeding the threshold, and then can jointly demodulate the data of all the blocks by using a plurality of DMRSs.

The third method comprises the following steps: and the receiving end compares the receiving power of the DMRS of each block in the transmission, performs power compensation on the DMRS symbols with the difference exceeding the threshold by adopting a predefined power scaling value, and then can jointly demodulate the data of all the blocks by using a plurality of DMRSs.

The above embodiments may be combined reasonably, for example as follows, but not as a limitation to other possible combinations of the present disclosure.

Combination of Modulation Coding Scheme (MCS) and resource proportion:

the overlapping part performs power scaling according to the requirement, and the power of the Non overlapping part is determined according to the following mode: when the ratio exceeds a threshold one (corresponding to the first predetermined threshold value in the above description) and when the modulation coding scheme of the transmission is amplitude dependent, then non overlapping also does the same power scaling as overlapping. Otherwise, the power of non overlapping is independent of the overlapping power scaling.

When the ratio does not exceed the threshold two (corresponding to the second predetermined threshold value in the above description) and when the modulation coding scheme of the above-described transmission is amplitude-dependent, the power of the overlapping part is zero.

MCS and block combination:

the overlapping part is required to be power-scaled, and the power of the Non overlapping part is determined as follows: when the modulation and coding scheme of the transmission is related to amplitude, the part of the non overlapping part belonging to the same block as the overlapping part also performs power scaling the same as the overlapping part, and the power of the other part of the non overlapping part is not related to the power scaling of the overlapping part.

Combination of resource proportions and tiles:

the overlapping part performs power scaling according to the requirement, and the power of the Non overlapping part is determined according to the following mode: when the proportion exceeds a threshold one, the part of the non overlapping part, which belongs to the same block as the overlapping part, is also subjected to power scaling the same as the overlapping part, and the power of the other part of the non overlapping part is not related to the power scaling of the overlapping part. Otherwise, the power of non overlapping is independent of the overlapping power scaling.

Combination of MCS, resource proportion and block:

the overlapping part is required to be power-scaled, and the power of the Non overlapping part is determined as follows: when the ratio exceeds a threshold one and the modulation coding mode of the transmission is related to amplitude, the part of the non overlapping and the overlapping part in the same block also performs power scaling same as the overlapping, and the power of the other part of the non overlapping is not related to the power scaling of the overlapping part. Otherwise, the power of non overlapping is independent of the overlapping power scaling.

When the ratio does not exceed the threshold two, and when the modulation coding scheme of the transmission is related to the amplitude, the power of the overlapping part is zero.

In all the implementation methods in the disclosure, after the overlapping part performs power scaling, the coefficient of the power scaling is zero, or when the transmission power of the overlapping part is 0, the power of the non-overlapping part is not affected by the power scaling of the overlapping part, that is, the power determination of the non-overlapping part is independent of the power scaling result of the overlapping part.

Specific example 5

For the part needing power scaling, the coefficient of the power scaling is selected as follows:

in all the implementation methods in the present disclosure, when power scaling of the non-overlapping part and the overlapping part is determined separately, or determined independently, or when power determination of the non-overlapping region is not affected by power scaling of the overlapping part, the power of the non-overlapping region and the overlapping region are determined according to the power limit in each region, or the remaining power and the priority compared to other transmission at the same time.

For the part needing power scaling in the above embodiment, the coefficient of power scaling is determined in one of the following ways.

The first method is as follows: and determining the power scaling coefficient according to the residual power and the transmission priority.

For example, the remaining power is allocated to the remaining transmission in the overlapping part of the multiple transmissions, and the highest priority transmission in the remaining transmissions is selected. If the priority has only one transmission, the transmission does not need power scaling if the remaining power meets the transmission power requirement of the transmission, and if the remaining power cannot meet the transmission power requirement of the transmission, the remaining power is completely distributed to the transmission; if the priority has a plurality of transmissions, the plurality of transmissions do not need to be power-scaled if the remaining power meets the sending power requirements of the plurality of transmissions, otherwise, the remaining power cannot meet the sending power requirements of the plurality of transmissions, the remaining power is all distributed to the plurality of transmissions, and at this time, the coefficients of the power-scaled of the plurality of transmissions are the same, or the coefficients of the power-scaled of the partial transmissions are zero, and the coefficients of the power-scaled of the remaining transmissions are the same.

The second method comprises the following steps: and determining the power scaling coefficient according to the residual power, the transmission priority and a predefined value list. Namely, the transmitted power scaling coefficient is determined according to the first mode and is set as PsFactor0, and the power scaling coefficient is adjusted to a value meeting the condition in the predefined value list. Specifically, the above conditions are: less than or equal to the maximum value of PsFactor 0.

For example, power scaling coefficient list: {1,3/4,1/2,1/4,0}, when the power scaling factor determined according to the above implementation is 0.8, then according to mode two, the value selected in the list is 3/4. This has the potential benefit that the receiver only needs to handle a few power ratios, reducing complexity.

The overlapping and non-overlapping in the present disclosure are generally directed to two kinds of transmissions, and when there are more than two kinds of transmissions, any two kinds of transmissions may be determined and operated accordingly in the manner described above in the present disclosure. When more than two transmissions exist, for two of them, the overlapping part and the non-overlapping part are only for the other of the two transmissions, and the non-overlapping part may be the overlapping symbol when more transmissions are considered. Regarding the prioritization:

there are several categories of uplink transmission: PRACH, PUCCH, PUSCH, SRS, generally, the priority of the above transmission is: PRACH > PUCCH > PUSCH > SRS.

In a carrier aggregation (carrier aggregation) scenario, there are multiple Component Carriers (CCs), and each CC is also called a serving cell. One of the CCs is configured as a PCell, and as a primary cell, has a higher priority than other CCs (scells), and a PUCCH is generally configured on the PCell. The PUSCH may also carry the content of the PUCCH, such as uci (uplink control Information), including ACK/NACK (positive and negative acknowledgement), SR (scheduling request), CSI (Channel State Information), and the like. In the CA scenario, the order of priority is: PRACH of PCell > PUCCH/PUSCH with ACK/NACK and/or SR > PUCCH/PUSCH with other UCIs > PUSCH w/o UCI > SRS/PRACH of Scell.

The priority between Long PUCCH and short PUCCH is: short PUCCH > Long PUCCH.

NR needs to guarantee priority of URLLC, so when there is URLLC traffic, at least one of the following priority orders should be considered:

PUSCH of URLLC > PUSCH of other services;

PUCCH of URLLC > PUCCH of other services;

PUSCH of URLLC > PUCCH of other services;

PUCCH of URLLC > PUSCH of URLLC;

specific example 6

How power scaling's coefficient selection tells the receiver:

the power scaling coefficient in the above embodiment may be notified to the receiving end by one of the following ways:

the first method is as follows: power scaling coefficients are carried by sequence information of the DMRS, and different sequences represent different coefficients.

The base station pre-configures the corresponding relation between the DMRS sequence and the power scaling coefficient for the UE. When UE needs to do power scaling for one transmission, determining a power scaling coefficient according to the residual power, the transmission priority and a predefined value list, setting the power scaling coefficient as PsFactor0, and then adjusting the power scaling coefficient to be the maximum value smaller than PsFactor0 in the power scaling value list which can be expressed by the predefined DMRS sequence. And finally, transmitting the DMRS sequence corresponding to the selected power scaling value in corresponding transmission.

The correspondence may be a fixed correspondence, for example, the list of power scaling coefficients corresponding to

sequences

1, 2, 3, and 4: {1,3/4,1/2,1/4}.

The corresponding relationship may also be a relative corresponding relationship, for example, the DMRS sequence determined in the authorization information or the scheduling information corresponding to the transmission represents a power scaling coefficient of 1, and a certain change is made on the basis of the DMRS sequence to represent other power scaling coefficients, for example, a rotation of a certain angle is made to represent another power scaling coefficient. Or represent other power scaling values with other sequences orthogonal thereto.

The receiving end needs to demodulate one by one a number of possible sequence attempts.

The changed DMRS sequence is only valid for the interval affected by power scaling.

The second method comprises the following steps: the receiving end is not explicitly informed, but the receiving end needs to do corresponding processing.

The receiving end processes the transmission in blocks, see the description of embodiment 4.

When the block division mode is not used, the whole transmission period of the transmission is regarded as one block.

And if the received power in the overlapping or potential overlapping area is less than a preset threshold, judging that the transmission power of the part is zero. Otherwise, after power compensation is carried out on the symbols of the DMRS, the data of the whole transmission period are jointly demodulated by the DMRS.

Specific example 7

Multiple transmissions, multiple overlapping part extensions:

many scenarios will have multiple transmissions sent in parallel:

in the same BWP, different channels and signals may have time domain overlapping regions

Different channels and signals may exist between the same CC and different BWPs, and between the CC and the CC, and the time domain overlapping area may exist between the different channels and signals

Double-connection or even multi-connection scene, different CCs may not be synchronous, and partial symbol time domain overlapping region may exist

Different physical layer transmission parameters numerology may be employed inside or between BWP, CC described above, resulting in different symbol lengths, and thus the minimum transmission time unit for different transmissions of the overlapping part may be different even though both are at the OFDM symbol level.

So the case of partial symbol overlap also needs to be treated as overlapping part.

In the time domain overlapping region, there may be multiple transmissions, and the minimum transmission unit of each transmission may be different or may not be time aligned. For example, each transmission may have a time unit that is one of: slot (slot), frame (frame), subframe (subframe), OFDM symbol, or time unit used by future systems. It should be noted that different transmitted OFDM symbols may also be different in length, and in relation to numerology, corresponding other units defined in terms of the number of OFDM symbols, such as subframes, slots, may also be different.

The transmission period (transmission period or transmission duration) of each transmission is described by a respective time unit. For example, transmission 1 is a subcarrier spacing of 15kHz, with OFDM symbol _1 as the time unit, transmission 2 is a subcarrier spacing of 60kHz, with OFDM symbol _2 as the time unit, when OFDM symbol 1 is 4 times OFDM symbol _ 2. If transmission 1 is 4 OFDM symbols (OFDM symbol _1 by default) and transmission 2 is 4 OFDM symbols (OFDM symbol _2 by default), the transmission period lengths of transmission 1 and transmission 2 are different.

The method of the present disclosure determines the power of the overlapping part and the non overlapping part for one transmission in overlapping. The partitioning of overlapping and non overlapping is also subject to the time unit of the corresponding transmission. When one transmission and different other transmission combinations have overlapping in different time periods, namely the overlapping part in the whole transmission period of the transmission is more than 1, the power scaling parts are processed one by one to obtain the power scaling coefficient of each overlapping part, and when the power scaling parts need to be unified in a plurality of different time periods in the transmission period, the minimum value in the power scaling coefficients of each overlapping part is adopted.

As shown in fig. 6, the transmission period of PUSCH is OFDM symbols 1 to 9, the first 3 OFDM symbols overlap with PRACH, this part is called overlapping1, the last 4 symbols overlap with PUCCH, this part is called overlapping2, and the middle 2 symbols are non-overlapping regions. If the power scaling coefficient of overlapping1 is 0.9 and the power scaling coefficient of overlapping2 is 0.8, and it is determined according to the present disclosure or other methods that uniform power scaling is required for multiple different time periods within the transmission period of the PUSCH, then the smallest of the power scaling coefficients of overlapping1 and overlapping2, i.e., 0.8, is used as the uniform power scaling value.

Based on such understanding, the technical solutions of the present disclosure may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present disclosure.
