In the embodiment of the present application, only the core network device in the NR system is described as an example, and the specific type of the core network device is not limited.

According to the signal transmission method provided by the embodiment of the application, the resource block region division of the MPR index can be redefined in the scene that the UE transmits the signal based on the extension PRB, and the terminal equipment can reset the MPR of the uplink transmission signal according to the redefined resource block region, so that the uplink transmission signal is transmitted based on the reset MPR. It will be appreciated that when the terminal device transmits the uplink transmission signal based on the reset MPR, after the parameters such as waveform, channel bandwidth, modulation order and the like are selected, the performance of the uplink transmission signal, such as peak-to-average ratio (Peak Average Power Ratio, PAPR) and the like, can be improved by some technologies, such as FDSS technology. For example, the terminal device may perform uplink transmission power enhancement on the uplink transmission signal through the FDSS technology of extension PRB.

FDSS is a frequency domain shaping technique used by RAN4, which can effectively reduce PAPR and obtain gain in performance. After a group of discrete time domain signals pass through a digital-to-analog converter (Digital Analog Converter, DAC), the peak-to-average ratio of the analog signals output by the discrete time domain signals has a certain relation with the correlation between the group of discrete time domain data. Assuming that a set of discrete time domain data signals y (n) is time domain convolved with a set of time domain discrete data d (n), yd (n) is obtained:

Assuming that the peak-to-average ratios of the output signals of y (n) and yd (n) after passing through the DAC are respectively PAPR1 and PAPR2, if d (n) is a set of designed weight coefficients, the correlation between adjacent data of yd (n) will be better than the correlation between adjacent data of y (n). The higher the correlation, the lower the PAPR, so PAPR2 will be smaller than PAPR1, after a set of discrete time domain data is convolved with a set of designed discrete data, PAPR can be reduced effectively.

According to the convolution theorem, the convolution operation of two time-domain signals may be equivalent to the dot-product operation of the two time-domain signals in the frequency domain. Therefore, the PAPR can be effectively reduced by transforming a set of discrete time domain data into discrete frequency domain data after discrete Fourier transform (Discrete Fourier Transform, DFT), then dot multiplying the designed spectrum shaping sequence, and then performing inverse discrete Fourier transform (Inverse Discrete Fourier Transform, IDFT) on the time domain signal. This technique of reducing PAPR operates better in the frequency domain because of the lower complexity of the point multiplication operation than the convolution operation, and is therefore referred to as FDSS technique.

When the terminal equipment modulates the uplink transmission signal by using the FDSS technology, the adjacent PRB of the allocated PRB can be reserved as the extension PRB, so that the frequency domain waveform of the uplink transmission signal is adjusted, a smoother waveform is obtained, the d (n) coefficient is optimized, and the PAPR is reduced. Reserved extension PRBs mainly include two modes, namely reserved space PRBs and reserved repetition PRBs.

Referring to fig. 2, a schematic diagram of spectrum shaping based on reserved idle PRBs according to an embodiment of the present application is shown. As shown in fig. 2, after the UE data is scheduled, some idle PRBs, i.e., extension PRBs, are reserved for it to put filter roll-off sidelobes therein. Compared with the mode of the close between the UEs, reserving some idle PRBs can reduce the roll-off amplitude requirement and the cut-off frequency requirement of UE windowing, smoother descent is realized at the roll-off position, sharper jitter is reduced, higher actual sending power can be obtained, and better performance improvement is obtained.

Referring to fig. 3, a schematic diagram of spectrum shaping based on repeated PRBs is shown in the present embodiment. As shown in fig. 3, the content of the first PRB of the transmission data PRBs, i.e., the allocated PRBs, is repeated and appended to the last of the transmission data PRBs, and the content of the last PRB of the transmission data PRBs is repeated and appended to the transmission PRBs, before forming the PRB bandwidth type as shown in fig. 3. This approach is better in correlation than the approach shown in fig. 2 for reserved repeated PRBs than for reserved idle PRBs, and thus may be able to have better performance enhancements.

It should be noted that, in the above example, only in the scenario where the UE performs signal transmission based on extension PRBs, the resource block region division of the MPR index is redefined, and after the MPR of the uplink transmission signal is redefined, the terminal device performs an exemplary description on the modulation process of the uplink transmission signal by using the FDSS technology based on extension PRBs. After the terminal device resets the uplink transmission signal, other processing may be performed on the uplink transmission signal based on the configuration information of the extension PRB and the reset MPR, which is not specifically limited herein in the embodiment of the present application.

The signal transmitting method provided by the embodiment of the application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.

In a first aspect, referring to fig. 4, a flowchart of a signal transmitting method provided in an embodiment of the present application is shown. The method is applied to the terminal equipment, as shown in fig. 4, and specifically the method may include:

step 401, the terminal equipment divides a resource block area of a maximum power back-off index based on a first parameter, wherein the resource block area comprises an allocated physical resource block and an expanded physical resource block;

step 402, the terminal equipment resets the maximum power back-off value of the uplink transmission signal according to the divided resource block area;

step 403, the terminal device transmits the uplink transmission signal based on the reset maximum power back-off value;

wherein the first parameter comprises any one of:

a1, distributing configuration information of physical resource blocks;

a2, distributing configuration information of the physical resource blocks and configuration information of the extended physical resource blocks.

It should be noted that the terminal device may be the terminal device 11 in fig. 1, and the embodiments of the present application are not described herein.

In the embodiment of the present application, when the terminal device divides the resource block region of the MPR index, only the configuration information of the allocated PRB may be considered, or both the configuration information of the allocated PRB and the configuration information of the extension PRB may be considered.

Optionally, the configuration information of the allocated physical resource blocks includes a starting position of the allocated physical resource blocks and the number of the allocated physical resource blocks.

The configuration information of the extended physical resource block includes:

expanding the number of physical resource blocks; or,

the number of extended physical resource blocks and the location of the extended physical resource blocks.

The allocated PRBs are in units of Resource Blocks (RBs), and when the allocated PRBs contain a plurality of RBs, the RBs are consecutive. The starting position of the allocated PRB is the position of the first RB in the allocated PRB, and the number of the allocated PRB is the number of continuous RBs contained in the allocated PRB.

Likewise, extension PRBs are in units of RBs, and when extension PRBs contain multiple RBs, the RBs may be contiguous, i.e., continuously distributed on one side of the allocated PRBs; alternatively, the RBs may be discontinuous, distributed on both sides of the allocated PRB. The extension PRBs are distributed immediately adjacent to the allocated PRBs, and RBs included in extension PRBs on either side of the allocated PRBs are continuous. The starting position of the extension PRB is the position of the first RB in the extension PRB, and the extension PRB is the sum of the number of RBs contained in the extension PRBs immediately adjacent to the allocated PRB. Illustratively, if the number of RBs included in the extension PRB on the left side of the allocated PRB is x1 and the number of RBs included in the extension PRB on the right side of the allocated PRB is x2, the number of RBs included in the extension PRB, that is, the number of extension PRBs in this application, x=x1+x2. Where x1 and x2 may both be greater than 0, or one of x1 and x2 may be greater than 0 and the other equal to 0.

The terminal device divides the resource block region of the MPR index according to any one of the first parameters A1 and A2. In the present application, the resource block region of the re-divided MPR index includes allocated PRBs and extension PRBs. In the related art, MPR is set only for allocated PRBs. Therefore, in the present application, after the resource block region of the MPR index is re-divided, the MPR value of the uplink transmission signal needs to be reset for the allocated PRB and extension PRB in the resource block region of the MPR index. Further, the terminal device transmits the uplink transmission signal according to the reset MPR value, so that the uplink transmission signal of the terminal device has more proper power under different modulation or channel bandwidths, which is beneficial to improving the performance of the uplink transmission signal.

Optionally, the first parameter includes configuration information of allocating physical resource blocks and configuration information of expanding physical resource blocks, and the terminal device divides a resource block area of the maximum power back-off indicator based on the first parameter, including: and under the condition that the first condition is met, the terminal equipment divides the resource block area of the maximum power back-off index based on the first parameter.

Wherein the first condition includes at least one of:

B1, the number of the extended physical resource blocks is larger than a first threshold;

b2, number of extended physical resource blocks, N _RB A ratio of (2) is greater than a second threshold value, said N _RB Is the maximum number of resource blocks given the signal bandwidth and subcarrier spacing;

b3, the ratio of the number of the extended physical resource blocks to the number of the allocated physical resource blocks is larger than a third threshold;

b4, the ratio of the number of the extended physical resource blocks to the sum of the number of the allocated physical resource blocks and the number of the extended physical resource blocks is larger than a fourth threshold value;

b5, the Modulation order (Modulation order) or Modulation and coding strategy (Modulation and Coding Scheme, MCS) index of the uplink transmission signal of the terminal device is smaller than a fifth threshold;

b6, the uplink transmitting signal of the terminal equipment adopts a spread spectrum orthogonal frequency division multiplexing (Discrete Fourier Transmission-Single Carrier-Orthogonal Frequency Division, DFT-S-OFDM) waveform based on discrete Fourier transform;

b7, the terminal equipment adopts a low peak-to-average power ratio (low Peak Average Power Ratio, low PAPR) sequence as a demodulation reference signal (Demodulation Reference Signal, DMRS) sequence.

In the application, when the terminal equipment divides the resource block region of the MPR index, the resource block region division can be directly performed based on A1 or A2 without considering other preconditions; the resource block region of the MPR index may be divided based on the configuration information of the allocated PRB and the configuration information of the extension PRB at the same time when the first condition is satisfied, that is, when at least one of the above-described B1 to B7 is satisfied.

The first threshold, the second threshold, the third threshold, the fourth threshold, and the fifth threshold may be configured by the network device or may be specified by a protocol.

The resource block region of the MPR index may be divided into three types of regions, i.e., an Inner region (Inner), an Edge region (Edge), and an Outer region (Outer), according to configuration types. The first parameters are different, and the configuration types of the resource block areas of the MPR index are also different.

In an optional embodiment of the present application, the first parameter includes configuration information of an allocated physical resource block and configuration information of an extended physical resource block. If the first parameter meets a second condition, the resource block region belongs to an inner region, and the second condition includes: l (L) _ERB +L _CRB The first value is less than or equal to the second value is less than or equal to the min (RB) _start ，RB _Estart ) The third numerical value is less than or equal to the third numerical value.

If the first parameter meets a third condition, the resource block region belongs to an edge region, and the third condition includes:

L _ERB +L _CRB A fourth value of less than or equal to the fourth value, and min (RB) _start ，RB _Estart ) At the leftmost end of the channel bandwidth; or,

wherein RB is _end To allocate end positions of physical resource blocks, RBs _Eend End position for expanding physical resource block; max (RB) _end ，RB _Eend ) Representing taking RB _end With RB _Eend Is the maximum value of (a).

And if the first parameter does not meet the second condition and the third condition, the resource block region belongs to an external region.

When the configuration information of the allocated PRB and the configuration information of the extension PRB are considered at the same time, the area to which the resource block area of the MPR index belongs in the channel may be determined according to the second condition and the third condition. Specifically, if the sum of the number of allocated PRBs and extension PRBs, that is, the sum of the number of RBs included in allocated PRBs and extension PRBs, is less than or equal to the first value, and the minimum value of the start position of allocated PRBs and the start position of extension PRBs, that is, the start position of the resource block region of the MPR index, is greater than or equal to the second value, less than or equal to the third value, it is indicated that the configuration information of allocated PRBs and the configuration information of extension PRBs satisfy the second condition, and the resource block region of the MPR index belongs to the inner region.

If the sum of the number of allocated PRBs and the number of extension PRBs is smaller than or equal to a fourth value, and the minimum value of the starting position of the allocated PRBs and the starting position of the extension PRBs, namely the starting position of a resource block area of an MPR index, is at the leftmost end of the channel bandwidth; or, the sum of the number of allocated PRBs and the number of extension PRBs is smaller than or equal to the fourth value, and the maximum value of the end position of the allocated PRBs and the end position of the extension PRBs, that is, the end position of the resource block region of the MPR index, is at the rightmost end of the channel bandwidth, which indicates that the configuration information of the allocated PRBs and the configuration information of the extension PRBs satisfy the third condition, and the resource block region of the MPR index belongs to the edge region.

If the configuration information of the allocated PRB and the configuration information of the extension PRB neither satisfy the second condition nor the third condition, it is indicated that the resource block region of the MPR index belongs to the outer region.

The first value, the second value, the third value and the fourth value may be fixed values or may be specified by a protocol.

As an example, a first value=ceil (N _RB Second value=max (1, floor (L) _CRB /2)), third value=n _RB –max(1,floor(L _CRB /2))–L _CRB The method comprises the steps of carrying out a first treatment on the surface of the A fourth value = 2, or the fourth value is specified by a protocol;

wherein N is _RB Is the maximum number of resource blocks given the signal bandwidth and subcarrier spacing, ceil (N) _RB And/2) is greater than or equal to N _RB /2Minimum integer, floor (L _CRB And/2) is less than or equal to L _CRB Maximum integer of/2, max (1, floor (L _CRB (2)) means 1 and floor (L) _CRB Maximum value in/2).

As another example, the first value, the second value, the third value, and the fourth value are all specified by a protocol.

In another alternative embodiment of the present application, the first parameter includes configuration information for allocating physical resource blocks. If the first parameter meets a fourth condition, the resource block region belongs to an inner region, and the fourth condition includes:

L _CRB ≤ceil(N _RB and max (1, floor (L) _CRB /2))≤RB _start ≤N _RB –max(1,floor(L _CRB /2))–L _CRB ；

Wherein L is _CRB To allocate the number of physical resource blocks, N _RB Is the maximum number of resource blocks given the signal bandwidth and subcarrier spacing, ceil (N) _RB And/2) is greater than or equal to N _RB The smallest integer of/2, floor (L _CRB And/2) is less than or equal to L _CRB Maximum integer of/2, max (1, floor (L _CRB (2)) means 1 and floor (L) _CRB Maximum value in/2), RB _start To allocate a starting position of a physical resource block.

If the first parameter meets a fifth condition, the resource block region belongs to an edge region, and the fifth condition includes: l (L) _CRB And less than or equal to 2, wherein the resource block area is positioned at the leftmost end or the rightmost end of the channel bandwidth.

And if the first parameter does not meet the fourth condition and the fifth condition, the resource block region belongs to an external region.

When only the configuration information of the allocated PRBs is considered, the area to which the resource block area of the MPR index belongs in the channel may be determined according to the fourth and fifth conditions. Specifically, if the number of allocated PRBs, i.e., the number of RBs contained in the allocated PRBs, is less than or equal to ceil (N _RB /2) and the starting position of the allocated PRB is greater than or equal to 1 and floor (L) _CRB Maximum value in/2), less than or equal to N _RB –max(1,floor(L _CRB /2))–L _CRB And the configuration information of the allocated PRB is indicated to meet a fourth condition, and the resource block region of the MPR index belongs to the inner region.

If the number of allocated PRBs is less than or equal to 2 and the resource block region of the MPR index is located at the leftmost end or the rightmost end of the channel bandwidth, it is indicated that the configuration information of the allocated PRBs satisfies the fifth condition, and the resource block region of the MPR index belongs to the edge region.

If the configuration information of the allocated PRB does not satisfy the fourth condition or the fifth condition, it may be determined that the resource block region of the MPR index belongs to an outer region.

It should be noted that, in the embodiment of the present application, the channel bandwidth includes at least one of a system bandwidth and a partial system bandwidth.

Optionally, the number of extended physical resource blocks satisfies any one of the following conditions:

c1, the number of the extended physical resource blocks is a fixed value, and the number of the extended physical resource blocks is irrelevant to the number of the allocated physical resource blocks;

c2, the number of extended physical resource blocks is not fixed, and the number of extended physical resource blocks is related to the number of allocated physical resource blocks.

In the embodiment of the present application, in the resource block region of the MPR index, the number of extension PRBs may be a fixed value, and there is no association between the number of extension PRBs and the number of allocated PRBs. Alternatively, the number of extension PRBs is not fixed and may be adaptively adjusted, but there is an association between the number of extension PRBs and the number of allocated PRBs, for example, the number of extension PRBs is linearly related to the number of allocated PRBs, or other functional relationships are satisfied.

Optionally, the location of the extended physical resource block satisfies any one of the following conditions:

d1, fixing the positions of the extended physical resource blocks, wherein the extended physical resource blocks are close to the allocated physical resource blocks and are symmetrically distributed on two sides of the allocated physical resource blocks;

D2, the positions of the extended physical resource blocks are not fixed, the extended physical resource blocks are close to the allocated physical resource blocks and are asymmetrically distributed on two sides of the allocated physical resource blocks, and the number of the extended physical resource blocks on each side of the allocated physical resource blocks is greater than or equal to 1;

d3, the positions of the extended physical resource blocks are not fixed, the extended physical resource blocks are close to the allocated physical resource blocks and are distributed asymmetrically on two sides of the allocated physical resource blocks, and the number of the extended physical resource blocks on one side of the allocated physical resource blocks is equal to 0.

Or, the position of the extension PRB is not fixed, the position of the extension PRB can be adaptively adjusted according to the position of the allocated PRB, and the extension PRB is asymmetrically distributed on two sides of the allocated PRB.
