Description

Method for determining size of resource, terminal and network side equipment

Technical Field

The application belongs to the technical field of communication, and particularly relates to a method for determining the size of a resource, a terminal and network side equipment.

Background

The inter-symbol interference (Inter Symbol Interference, ISI) performance of the orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) multi-carrier system is better, but the weakness of OFDM is that the size of the subcarrier interval is limited, so that in the case of coping with high-speed moving scenarios (such as high-speed rail), due to the large doppler shift caused by the large relative speed between the receiving and transmitting ends, the orthogonality between OFDM subcarriers is destroyed, and serious inter-carrier interference (INTER CARRIER INTERFERENCE, ICI) is generated between subcarriers.

The proposal of the orthogonal time-frequency space domain (Orthogonal Time Frequency Space, OTFS) technology is aimed at solving the problems in the above OFDM system. The OTFS technique defines a transformation between a delay-doppler domain and a time-frequency domain, and by mapping communication data and pilot frequencies to the delay-doppler domain at the transceiver end, the coupling interference between data samples is reduced, and additional diversity gain and channel estimation gain are obtained.

The OTFS technology has the remarkable characteristics that the unique pilot frequency design in the delay Doppler domain can realize the perception function of the system through the pilot frequency; meanwhile, the communication function of the system can be realized through the communication data, however, since the communication data and the pilot frequency are mapped on the delay-doppler domain resource together, the trade-off between the perception index and the communication index cannot be realized, for example, the communication index cannot be satisfied when the perception index is satisfied, or the perception index cannot be satisfied when the communication index is satisfied.

The interference term contains echoes of all data parts, and pilot echoes that go through the NLOS path, the ambient clutter and thermal noise are collectively defined as noise w _N, and/>Note that in a strict sense,/>And/>/>, S and D in delay and doppler dimensions, respectivelyCyclically shifted versions, and with element-wise phase shifts. Since this fixed phase shift does not affect the perceived detection and can be easily compensated for after the perceived detection yields CSI, the phase shift can be ignored for modeling analysis for simplicity.

By usingAnd/>Respectively representing a pilot symbol matrix and a data symbol matrix of the delay-doppler domain. The pilot frequency block is located in a pilot frequency symbol matrix, the size of the pilot frequency block is N _P×M_P, and the symbol values of the pilot frequency symbol matrix except the pilot frequency block are all zero. The data symbol matrix in the delay-doppler domain is the result of the SFFT conversion of the modulation symbol matrix in the time-frequency domain into the delay-doppler domain. X is the matrix of transmitted symbols and,

The receiving side uses Y and S _[a,b] to perform linear correlation operation, and judges the position of the LOS path echo on the delay Doppler plane according to the obtained accumulated power of the correlation signals. For perception, it is generally assumed that the reflection path of the target is the LOS path. Meanwhile, under the distinguishable condition, the reflection paths of the targets are at least one of different delays or Doppler, namely tau _i≠τ_j or ν _i≠ν_j, i noteq j.

It is assumed that a certain moving object corresponds to the distance and speed of a communication awareness Integrated (ISAC) machine, respectively (τ ₀,v₀). And performing linear correlation detection on the perception receiving side by using the cyclic shift S _[a,b] of S. When (when)When the method is used, the following steps are included:

Wherein the method comprises the steps of Ρ _0i＜＜M_PN_P was found by numerical verification.

Wherein the method comprises the steps ofPsi _0i＜＜M_PN_P is known by numerical verification and is the term/>Or/>When ψ _0i =0. σ is the standard deviation of the noise random variable, and its variance σ ² is the noise power density over the delay-doppler domain, i.e. the noise power over each delay-doppler domain resource grid. /(I)As can be seen from the numerical verification, ζ < M _PN_P, as shown in fig. 3,4 and 5, fig. 3 is a CCDF curve of pilot and random noise/data inner product, with M _P＝15,N_P =15 for 10000 cycles; fig. 4 is a CCDF curve of pilot and random noise/data inner product, with M _P＝63,N_P = 63 for 10000 cycles; fig. 5 is a CCDF curve of pilot and random noise/data inner product, with M _P＝255,N_P = 255 for 10000 cycles.

From fig. 3,4 and 5, the following law can be seen: first, ρ _0i is approximately co-distributed with ζ, so the impact of data and noise on perceived SINR depends only on the respective average powers. Second, as M _PN_P increases, the difference between the pilot and the inner product of data/noise is larger than the inner product of itself, meaning that the detection performance is improved.

Based on the above properties, M _P＝M,N_P =n is the most preferred scheme, regardless of the computational complexity. In particular, when M _P＝M,N_P =n, there are:

Wherein, And can verify/>The perceived SINR is optimal at this point.

At the same time, whenThat is, when the receiving side S _[a,b] does not match (overlap) the LOS path received signal, there are:

For perceptual scenes, h ₀＞＞h_j is usually assumed, thus/>Directly reflects the difference between the linear correlation peak value of the LOS path and other reflection paths, and the false detection rate of the detection of the perception target is mainly determined

As can be seen from the analysis of (3), when linear correlation detection is adopted, the detection SINR of the perceived signal is defined as:

When M _PN_P = MN, there are:

Wherein the method comprises the steps of Which is the signal to noise ratio of the system.

In the first term of the denominator of equation (6), MN is determined as ρ _0i. At this timeThe size of (2) depends on two factors: /(I)I.e., the ratio of the channel gains of the LOS path to all interference paths; /(I)I.e., the power ratio of the data and pilot. Clearly, to enhance perceived performance, it is desirable/>

In the second term of the denominator of equation (6),Is LOS diameter and is/>The ratio of the sum of the channel gains of all interference paths that are weights. Due to the weighting factor/>The perceived signal power of the interference path is significantly suppressed.

In the third term of the denominator of equation (6), the influence of the ambient noise is then determined by a factor of the coefficientsInhibition was performed.

In fact, by combining the pilot design with linear correlation detection, the pilot block can be regarded as a precoding matrix, which is used to project the signal power on the M _P×N_P -sized resource onto the signal subspace defined by the precoding matrix, while most of the power of the echo interference and the environmental noise is projected outside the signal subspace, so that the significant interference and noise suppression effects are represented.

Meanwhile, although the perceptual performance is best when M _P＝M,N_P =n, larger M _P and N _P increase the complexity of channel estimation for the communication receiving side. In some scenarios, M _p＜M,N_P < N may still be set due to terminal capability limitations.

For single station perception, the perceived channel is generally considered to be a double pass of the communication channel, and the delay and Doppler of the perceived channel are both twice that of the communication channel, so that the channel quality of the communication channel is better than that of the perceived channel; for multi-station perception, the perceived receiver can be regarded as a communication receiver that performs channel estimation only, without demodulation decoding. Thus if the transmitted signal meets the perceived channel estimation requirements, it can be assumed that the channel estimation accuracy requirements of the communication are also met.

Evaluating the communication performance of a single link typically has two dimensions: bit error rate and throughput. In the case of modulation coding parameter determination, the bit error rate is mainly affected by the channel estimation accuracy, and the throughput is mainly affected by the bit error rate and the number of transmitted information bits. Channel estimation methods similar to perceptually can also be used for channel estimation of communication signals in the delay-doppler domain. In the technical scheme of the invention, the throughput of the communication service mainly depends on the error rate and the MCS parameter because the number of the resources is determined. Because the delay Doppler domain pilot frequency can better perform communication channel estimation, and then interference elimination can be utilized to reduce interference of the pilot frequency to data, good data demodulation performance can be obtained under high signal-to-noise ratio.

The first embodiment describes a pilot block configuration procedure applicable to a task-aware priority scenario; the second embodiment introduces a pilot block configuration flow suitable for the communication task priority scenario.

Example 1

Embodiment one is applicable to a perceived task priority scenario. The embodiment mainly solves the problem of how to achieve the unification of communication and perception indexes by using the same communication perception signals in an ISAC system.

Step one:

A communication awareness Integrated (ISAC) transmitter determines the size of M and N, i.e., the passband frame size, according to a system's awareness resolution index, where M is determined by delay resolution and N is determined by Doppler resolution.

To reduce overhead, the protocol may be preconfigured with a set of frame structure combinations, given in the form of an indexed list, as shown in table 1.

Table 1 frame structure configuration table

Indexing of	Frame structure	Target bit error rate (optional)
			1	[M₁,N₁]	E₁
2	[M₂,N₂]	E₂
			…	…
L	[M_L,N_L]	E_L

For the communication counterpart, the ISAC transmitter indicates a specific value of the frame structure configuration, or an index thereof, to the communication reception side by: 1) A synchronization signal (implicit) indication; 2) Explicit indication in PBCH; 3) DCI explicit indication in PDCCH; 4) Explicit indication in SIB; 5) Explicit indication in RRC.

For the perception peer, single station perception need not be indicated. The multi-site awareness then the ISAC transmitter indicates to the communication receiving side the specific value of the frame structure configuration, or its index, by: 1) And forwarding to the perception opposite end through the base station or the dedicated SCN configuration. And transmitted over the communication link (if any) between the ISAC transmitter and the sensing counterpart. And may be indicated in the manner of the preceding paragraphs 1) -5).

Step two, including two cases of option 1 and option 2.

Option 1: the ISAC transmitter transmits information triggering one 1 bit (bit), activating the transmission of a passthrough frame.

The information may be transmitted in a master information block (Master Information Block, MIB) in the PBCH, a synchronization signal, or a SIB in a physical downlink shared Channel (Physical Downlink SHARED CHANNEL, PDSCH)/PDCCH, RRC, DCI, a medium access Control element (MEDIA ACCESS Control Control Element, MAC CE), a reference signal, or a side link Control information (Sidelink Control Information, SCI) in a physical side link Control Channel (PHYSICAL SIDELINK Control Channel, PSCCH).

The communication receiving side is preconfigured with a capability identification at the time of shipment. Upon receiving the trigger signaling, the communication receiver sends its own capability report message, which may be a capability identification, to the ISAC transmitter. This information may be sent in a message in RACH, or RACH Preamble, or RRC, UCI, or SCI (side link) in PDSCH/PDCCH.

The ISAC transmitter receives the capability report message, and selects appropriate M _P and N _P according to the processing capability of the corresponding receiving end.

Option 2: the ISAC transmitter transmits signaling configurations M _P and N _P, activating the transmission of the passthrough frame.

This information may be sent in MIB in PBCH, synchronization signal, or SIB, RRC, DCI, MAC CE in PDSCH/PDCCH, reference signal, or SCI in PSCCH.

The communication receiving side is preconfigured with a capability identification at the time of shipment. Upon receiving the M _P and N _P signaling configuration, the communication receiver sends an indication of 1bit to the ISAC transmitter, e.g., 0 for Acknowledgement (ACK), 1 for Negative (NACK), indicating whether the current M _P and N _P are in the processing capability category. This information may be sent in a message in RACH, or a random access Preamble (RACH Preamble), or RRC in PDSCH/PDCCH, uplink control information (Uplink Control Information, UCI), or SCI (side link).

After receiving the 1bit indication identification message, the ISAC transmitter does not need to process if the 1bit indication identification message is 0; if 1, then the smaller M _P and N _P are reselected.

The ISAC system configures the selected M _P and N _P, and pilot block power, for transmission to the communication receiving side.

For simple implementation, the protocol may be pre-configured with an index table, as shown in table 2. Table 2 may be a protocol pre-configuration, or an ISAC transmitting side may be configured to a communication/perception receiving side through RRC.

Table 2 pilot block configuration table

For the communication counterpart, the ISAC transmitter indicates the specific value of the pilot block configuration, or its index, to the communication receiving side by: 1) A synchronization signal (implicit) indication; 2) Explicit indication in PBCH; 3) DCI explicit indication in PDCCH; 4) Explicit indication in SIB; 5) Explicit indication in RRC.

For the perception peer, single station perception need not be indicated. The multi-station awareness then requires the ISAC transmitter to configure the specific values of the pilot blocks, or their indexes, to indicate to the awareness receiving side by: 1) And forwarding to the perception opposite end through the base station or the dedicated SCN configuration. And transmitted over the communication link (if any) between the ISAC transmitter and the sensing counterpart. And may be indicated in the manner of the preceding paragraphs 1) -5).

Step three

The communication receiving side performs demodulation and decoding of communication data according to the configuration of the ISAC transmitter. And judging whether the configuration needs to be adjusted according to the target error rate indicated by the ISAC transmitter. The target bit error rate may be indicated in step one.

Let the actual error rate recorded on the receiving side be E _t. And according to whether the actual error rate is smaller than the target error rate, the communication receiving side transmits a 1-bit feedback indication message to the ISAC transmitter. For example, 1 denotes E _t≥E_l, 0 denotes E _t＜E_l, and l configures an index for a currently used frame structure.

Step four:

the ISAC transmitter adjusts the power allocation between pilot and data based on the feedback message from the communication receiver.

If the feedback indication message is 0, the current configuration continues to be used.

If the received feedback indication message is 1, adjusting the power distribution between the pilot frequency and the data, reducing the pilot frequency block power and/or increasing the data block power.

Case 1: the ISAC transmitter reconfigures a set of pilot block powers and data block powers from table 2 to achieve a decrease in pilot block power and/or an increase in data block power.

Case 2: the ISAC transmitter transmits one of the following according to a preconfigured adjustment step size Δp: 1) 1bit indication message, reducing pilot block power; or 2) 1bit indication message, increasing the power of the data block; or 3) a 2bit indication message, reducing pilot block power and increasing data block power.

Assuming that the perceived SNR requirement of the system requirement needs to meet a predefined threshold c, i.e., Z.gtoreq.c, note (6), so after adjustment according to case 1 or case 2, the selectionAnd/>The following formula needs to be satisfied: /(I)

Selection/>, by determining the relationship of Z to cAnd/>

Example two

The second embodiment is mainly applied to a communication priority scenario, in which the perception belongs to "best effort", and if the requirement on the perceived performance is severe, the second embodiment can be executed according to the first embodiment, and the second embodiment includes the following steps.

Step one:

The ISAC transmitter determines the size of the communication required communication sense frame and the size of the pilot block according to the communication throughput requirement of the system and the processing capability of the communication receiving side (the processing capability can be determined by option 1 in the first embodiment).

In fact, for the perceptual function, M determines the delay resolution at this time, while N determines the doppler resolution. To reduce overhead, the protocol may be preconfigured with a set of frame structure combinations, given in the form of an indexed list, which may be represented using table 3.

Table 3 frame structure and pilot block configuration table

For the perception peer, single station perception need not be indicated. The multi-station awareness then requires the ISAC transmitter to configure the pilot block with a specific value, or index thereof, indicated to the communication receiving side by: 1) And forwarding to the perception opposite end through the base station or the dedicated SCN configuration. And transmitted over the communication link (if any) between the ISAC transmitter and the sensing counterpart. And may be indicated in the manner of the preceding paragraphs 1) -5).

Step two:

The perception receiving side carries out perception target detection according to the configuration of the ISAC transmitter and calculates perception SINR at the same time. And determines whether an adjustment configuration is required based on the target perceived SINR Z _l indicated by the ISAC transmitter. And according to whether the perceived SINR is smaller than the target perceived SINR, the perceived receiving side sends a 1-bit feedback indication message to the ISAC sender. For example, 1 represents Z _l≥Z_t, i.e., the actual SINR is greater than or equal to the target SINR indicator; 0 indicates Z _l＜Z_t, i.e. the actual SINR is smaller than the target SINR indicator, l is the currently used configuration index.

Step three:

the ISAC transmitter adjusts the configuration based on feedback messages from the receiver aware.

And if the received feedback indication message is 1, adjusting the power distribution between the pilot frequency and the data.

Case 1: the ISAC transmitter reconfigures a set of pilot block powers and data block powers from table 3 to achieve a decrease in pilot block power and/or an increase in data block power.

Case 2: the ISAC transmitter transmits according to a preconfigured adjustment step size Δp: 1) 1bit indication message, reducing pilot block power; or 2) 1bit indication message, increasing the power of the data block; or 3) a 2bit indication message, reducing pilot block power and increasing data block power.

For the communication peer, the ISAC transmitter will indicate to the communication receiving side the specific values reconfigured according to the frame structure and pilot block, or its index, by: 1) A synchronization signal (implicit) indication; 2) Explicit indication in PBCH; 3) DCI explicit indication in PDCCH; 4) Explicit indication in SIB; 5) Explicit indication in RRC.

For the perception peer, single station perception need not be indicated. The multi-station awareness then requires the ISAC transmitter to reconfigure the frame structure and the pilot block to specific values, or its index, indicated to the communication receiving side by: 1) And forwarding to the perception opposite end through the base station or the dedicated SCN configuration. And transmitted over the communication link (if any) between the ISAC transmitter and the sensing counterpart. And may be indicated in the manner of the preceding paragraphs 1) -5).
