CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to a Chinese patent application filed with the Chinese Patent Office on December 2, 2022, with application number 202211538584.9 and title “Transmission Control Method, Device and Communication Equipment”, the entire contents of which are incorporated by reference in this application.

Background technique

Backscatter Communication (BSC) refers to the use of radio frequency signals from other devices or environments by backscatter communication equipment to modulate signals to transmit information (as shown in Figure 2).

As shown in FIG3 , a simple implementation of backscatter communication is: when the tag needs to send ‘1’, it reflects the incident carrier signal of the reader, and when the tag needs to send ‘0’, it does not reflect.

In order to facilitate understanding of the transmission control method of the embodiment of the present application, the following related technologies are first introduced:

1. Backscatter communication equipment

The backscatter communication device can be one of the following:

The first type: the backscatter communication device in the traditional RFID is generally a tag, which belongs to the passive IoT Devices (Passive-IoT);

The second type: semi-passive tags, which have a certain amplification capability in downlink reception or uplink reflection.

The reflection coefficient of the signal can be characterized as:

Where _Z0 represents the antenna characteristic impedance and _Z1 represents the load impedance.

Assuming the incident signal is S _in (t), the output signal is Therefore, corresponding amplitude modulation, frequency modulation or phase modulation can be achieved by properly controlling the reflection coefficient.

As shown in FIG5 , in the protocol design of ultra-high frequency (UHF) RFID, in the inventory mode, the reader is required to send a query command (Query), and the tag responds (Reply), that is, generates a 16-bit random number to the reader, and then the reader sends the sequence to the tag through the ACK command, and the tag sends the relevant data to the reader.

RN16 in FIG5 represents a random number with a length of 16 bits; PC represents protocol control. control); PacketCRC stands for packet cyclic redundancy check.

The transmission control method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

In the first aspect, referring to FIG. 6 , which is a flow chart of a transmission control method provided in an embodiment of the present application, the method may include the following steps 601 to 602:

Step 601: The first communication device estimates the target offset of the second communication device.

Here, the first communication device may be a Reader, wherein the Reader may be a network side device or a terminal. The second communication device may be a Tag.

The target offset is used to indicate the time domain offset and/or frequency domain offset of the signal transmitted by the second communication device. It can be seen that the first communication device can estimate the time domain offset and/or frequency domain offset of the signal transmitted by the second communication device. For example, if the first communication device is a Reader and the second communication device is a Tag, the Reader can estimate the time domain offset and/or frequency domain offset when the Tag transmits the signal.

In addition, the above-mentioned time domain offset is the time domain resource used by the second communication device when transmitting a signal, which is an offset relative to the already configured time domain resource; the above-mentioned frequency domain offset is the frequency domain resource used by the second communication device when transmitting a signal, which is an offset relative to the already configured frequency domain resource.

Optionally, the target offset includes at least one of the following items A-1 to A-2:

Item A-1: frequency offset value;

Item A-2: a duration offset value of a target object, wherein the target object includes at least one of a transmission unit symbol, a code chip, a high level, and a low level.

The above item A-1 is the offset value of the frequency used by the second communication device when transmitting a signal relative to the configured frequency;

The above-mentioned item A-2 indicates that the first communication device can estimate at least one of the duration offset value of the transmission unit symbol, the duration offset value of the code bit, the duration offset value of the high level, the duration offset value of the low level, and the duration offset value of the high level and the low level when the second communication device transmits a signal.

Here, the duration offset value of the transmission unit symbol is the offset value of the duration of the transmission unit symbol used by the second communication device to transmit the signal relative to the duration of the transmission unit symbol that has been configured to transmit the signal;

The chip duration offset value is the offset value of the chip duration used by the second communication device to transmit a signal relative to the configured chip duration used to transmit a signal;

The high-level duration offset value is, that is, the high-level duration of the transmission signal of the second communication device, relative to the high-level duration of the transmission signal that has been configured;

The low-level duration offset value is the low-level duration of the transmission signal of the second communication device, which is an offset value relative to the low-level duration of the transmission signal that has been configured;

The high level and low level duration offset value is the offset value of the high level and low level duration of the transmission signal of the second communication device relative to the high level and low level duration of the transmission signal that has been configured.

Step 602: The first communication device sends parameter information of the target offset to the second communication device.

Among them, after the second communication device receives the parameter information of the target offset sent by the first communication device, it can adjust the time domain resources and/or frequency domain resources of the signal transmitted by the second communication device according to the parameter information, thereby using the adjusted time domain resources and/or adjusted frequency domain resources to transmit the signal.

It can be seen from the above steps 601 to 602 that in an embodiment of the present application, the first communication device can estimate the target offset of the second communication device, and the target offset is used to indicate the time domain offset and/or frequency domain offset of the signal transmitted by the second communication device, so that the first communication device sends parameter information of the target offset to the second communication device. It can be seen that in an embodiment of the present application, the first communication device can estimate the time domain offset and/or frequency domain offset of the signal transmitted by the second communication device, thereby indicating the parameter information of the offset to the second communication device, so that the second communication device can adjust the time domain resources and/or frequency domain resources based on the offset, thereby reducing the probability of the time domain resources and/or frequency domain resources of the signal transmitted by the second communication device interfering with the time domain resources and/or frequency domain resources of other signals, thereby improving the communication quality.

Optionally, the above step 601 “the first communication device estimates the target offset of the signal transmitted by the second communication device” includes:

The first communication device respectively calculates the correlation between the synchronization sequence and each candidate sequence in the first set to obtain a corresponding correlation sequence, wherein the synchronization sequence is a synchronization sequence of a signal transmitted by the second communication device and received by the first communication device, and different candidate sequences correspond to different target offsets;

The first communication device selects the maximum value of each of the related sequences to form a target sequence;

The first communication device selects at least one value from the target sequence as a target correlation value;

The first communication device determines the target offset corresponding to the candidate sequence corresponding to the target correlation value as the target offset of the signal transmitted by the second communication device.

Here, the candidate sequence corresponding to the target correlation value is the candidate sequence corresponding to the correlation sequence to which the target correlation value belongs.

It can be seen that a first set is stored on the first communication device side, and the first set includes multiple candidate sequences, and each candidate sequence corresponds to a corresponding target offset (i.e., time domain offset and/or frequency domain offset). Here, the target offset corresponds to the waveform of the transmission signal of the second communication device. By sampling the waveform according to the sampling frequency corresponding to the transmission signal waveform after the target offset, a discrete sequence can be obtained, and the discrete sequence is the candidate sequence corresponding to the target offset.

For example, if the first set includes L candidate sequences, the correlation sequence between the synchronization sequence and each candidate sequence can be calculated respectively to obtain L correlation sequences, and then the maximum value in each correlation sequence can be selected respectively to obtain a target sequence with L values, and then at least one value can be selected from the target sequence as the above target correlation value. The target offset corresponding to the candidate sequence corresponding to the target correlation value is the target offset of the second communication device transmission signal estimated by the first communication device.

For example, the candidate sequences in the first set are {A1 A2 A3 A4 A5}, where the A3 sequence is a sequence without frequency domain offset and time domain offset. At this time, the sampling rate per symbol corresponding to the sequence is 48. Then, each candidate sequence in the first set is The sampling rates corresponding to the candidate sequences are: {48-2x, 48-x, 48 48+x, 48+2x} (that is, each candidate sequence has a corresponding sampling frequency);

If the target waveform is the waveform of the signal sent by the second communication device, then the synchronization sequence obtained based on the target waveform is correlated with each candidate sequence in the aforementioned A1 to A5 sequences to obtain 5 correlation sequences, so that the maximum values can be selected from the 5 correlation sequences respectively. These 5 maximum values constitute a target sequence, and then at least one value can be selected from the target sequence as the above-mentioned target correlation value. For example, the selected target correlation value belongs to the correlation sequence corresponding to the A3 sequence, then the target offset corresponding to the A3 sequence is the target offset of the above-mentioned target waveform sent by the second communication device estimated by the first communication device (that is, the first communication device estimates that the above-mentioned target waveform sent by the second communication device has not undergone frequency domain offset and time domain offset).

It can be seen that in the embodiment of the present application, the first communication device can use the correlation value comparison method to estimate the target offset of the second communication device.

Optionally, the first communication device selects at least one value from the target sequence as a target related value, including:

The first communication device selects the top M values in the target ranking as the target related values, wherein the target ranking is the ranking of the values in the target sequence from large to small, and M is greater than zero and less than or equal to the total number of values in the target sequence.

That is, the first communication device can select the top M values in the target ranking as the target related value (for example, the maximum value in the target sequence can be selected as the target related value, or the maximum value, the second maximum value, and the third maximum value in the target sequence can be selected as the target related value). Here, the specific value of M can be set on the network side.

Optionally, the parameter information includes at least one of the following items B-1 to B-4:

Item B-1: frequency offset value;

Item B-2: a second set and a first index, wherein the second set includes at least one frequency offset value, and the first index includes an index of at least one frequency offset value in the second set;

Item B-3: duration offset value of the target object, the target object including at least one of a transmission unit symbol, a chip, a high level, and a low level;

Item B-4: a third set and a second index, wherein the third set includes at least one duration offset value of the target object, and the second index includes an index of the duration offset value of at least one target object in the third set.

The above item B-1 indicates that if the target offset of the second communication device estimated by the first communication device includes a frequency offset value, the first communication device may indicate the frequency offset value to the second communication device.

The above item B-2 indicates that a second set can be maintained on the first communication device side, and the second set includes at least one frequency offset value. If the target offset of the second communication device estimated by the first communication device includes a frequency offset value, the first communication device can indicate the second set and the index of the frequency offset value estimated by the first communication device in the second set to the second communication device.

The above item B-3 indicates that if the target offset of the second communication device estimated by the first communication device includes a duration offset value of the target object, the first communication device may indicate the duration offset value of the target object to the second communication device.

Item B-4 above indicates that a third set can be maintained on the first communication device side, and the third set includes at least one duration offset value of a target object. If the target offset of the second communication device estimated by the first communication device includes the duration offset value of the target object, the first communication device can indicate the third set and the index of the duration offset value of the target object estimated by the first communication device in the third set to the second communication device.

It can be understood that the frequency offset value estimated by the first communication device can be one or more. If the frequency offset value estimated by the first communication device is multiple, the first index in the above item B-2 includes multiple indexes in the second set; similarly, the duration offset value of the target object estimated by the first communication device can also be one or more. If the duration offset value of the target object estimated by the first communication device is multiple, the second index in the above item B-4 includes multiple indexes in the third set.

Optionally, the second set is: [-N*offset, ..., -2*offset, -offset, 0, offset, 2*offset, ..., N*offset], wherein offset represents the step size of the frequency offset value, and N represents the range value of the frequency offset value;

and / or,

The third set is [-K*T_offset, ..., -2*T_offset, -T_offset, 0, T_offset, 2*T_offset, ..., K*T_offset], where T_offset represents the step size of the duration offset value of the target object, and K represents the range value of the duration offset value of the target object.

It can be seen from this that the frequency offset values in the above-mentioned second set can be sorted in order from small to large, and the interval between each two adjacent frequency offset values is the first preset value (that is, the above-mentioned offset); and/or, the duration offset values of the target objects in the above-mentioned third set can be sorted in order from small to large, and the interval between the durations of each two adjacent target objects is the second preset value (that is, the above-mentioned T_offset).

Optionally, the method further comprises:

The first communication device receives the hardware capability information and the frequency offset range of the second communication device sent by the second communication device;

At least one of offset, T_offset, N, and K is determined according to the hardware capability information and the frequency offset range of the second communication device.

That is, the interval between each adjacent two frequency offset values in the second set, and/or the interval between each adjacent two target object durations in the third set, are determined according to the hardware capability information and the frequency offset range of the second communication device;

The maximum value of the frequency offset values in the second set and/or the maximum value of the duration offset values of the target objects in the third set are determined according to the hardware capability information and the frequency offset range of the second communication device;

The minimum value of the frequency offset values in the second set and/or the minimum value of the duration offset values of the target objects in the third set are determined according to the hardware capability information and the frequency offset range of the second communication device.

Optionally, the parameter information is carried in at least one of the following items C-1 to C-4:

Item C-1: Control orders for inventory taking;

Item C-2: Control orders for inquiry;

Item C-3: Read control commands;

Item C-4: Send a control command to query the identity of the second communication device.

Among them, the identity identification in the above item C-4 can be a temporary identity identification.

It can be seen from this that the first communication device can carry the parameter information of the above-mentioned target offset in at least one of the above-mentioned items C-1 to C-4 and send it to the second communication device.

In the second aspect, referring to FIG. 7 , which is a flowchart of another transmission control method provided in an embodiment of the present application, the method may include the following steps 701 to 702:

Step 701: The second communication device receives parameter information of the target offset sent by the first communication device.

Item A-1: frequency offset value;

Step 702: The second communication device adjusts the time domain resources and/or frequency domain resources of the signal transmitted by the second communication device according to the parameter information.

It can be seen from the above steps 701 to 702 that in an embodiment of the present application, the first communication device can estimate the target offset of the second communication device, and the target offset is used to indicate the time domain offset and/or frequency domain offset of the signal transmitted by the second communication device, so that the first communication device sends parameter information of the target offset to the second communication device. It can be seen that in an embodiment of the present application, the first communication device can estimate the time domain offset and/or frequency domain offset of the signal transmitted by the second communication device, thereby indicating the parameter information of the offset to the second communication device, so that the second communication device can adjust the time domain resources and/or frequency domain resources based on the offset, thereby reducing the probability of the time domain resources and/or frequency domain resources of the signal transmitted by the second communication device interfering with the time domain resources and/or frequency domain resources of other signals, thereby improving the communication quality.

Item B-1: frequency offset value;

The above item B-4 indicates that: a third set may be maintained on the first communication device side, and the third set includes at least one duration offset value of a target object. If the target offset of the second communication device estimated by the first communication device includes the duration offset value of the target object, then the first communication device may store the third set and the target offset of the second communication device estimated by the first communication device. The index of the calculated duration offset value of the target object in the third set is indicated to the second communication device.

and / or,

Optionally, the method further comprises:

The second communication device sends hardware capability information and a frequency offset range of the second communication device to the first communication device;

Item C-1: Control orders for inventory taking;

Item C-2: Control orders for inquiry;

Item C-3: Read control commands;

It can be seen that the first communication device can carry the parameter information of the target offset in the above items C-1 to C-4. At least one of the items is sent to the second communication device.

Optionally, after the second communication device adjusts the time domain resources and/or frequency domain resources of the second communication device transmitting the signal according to the parameter information, the method further includes:

The signal is transmitted in the first time using the adjusted time domain resources and/or the adjusted frequency domain resources.

Optionally, the method further comprises:

In case the parameter information is not received, the signal is transmitted within the second time period using predetermined time domain resources and frequency domain resources.

It can be seen from this that when the second communication device receives the parameter information of the target offset sent by the first communication device, it can use the time domain resources and/or the adjusted frequency domain resources according to the parameter information to transmit the signal within the first time; when the second communication device does not receive the above parameter information, it can use the predetermined time domain resources and frequency domain resources (i.e., the default time domain resources and frequency domain resources) to transmit the signal within the second time.

Optionally, the priority of the first time is higher than the second priority, that is, when the above-mentioned parameter information is received, the priority of transmitting the signal using the time domain resources adjusted according to the parameter information and/or the adjusted frequency domain resources is higher than the priority of transmitting the signal using predetermined time domain resources and frequency domain resources.

In summary, the specific implementation of the transmission control method of the embodiment of the present application can be described as follows:

On the Reader side, the second set [-N*offset,….,-2*offset,-offset,0,offset,2*offset,…,N*offset] and/or the third set [-K*T_offset,…,-2*T_offset,-T_offset,0,T_offset,2*T_offset,…,K*T_offset] are maintained.

Among them, offset represents the step size of the frequency offset value, T_offset represents the step size of the duration offset value of the target object, N represents the range value of the frequency offset value, K represents the range value of the duration offset value of the target object, and the target object includes at least one of the transmission unit symbol, code bit, high level, and low level; the parameters N, offset, T_offset, and K can be set to different values according to the hardware capabilities reported by the Tag and the frequency offset range of the Tag.

In addition, each frequency offset value corresponds to an estimated tag carrier frequency or the duration of the target object. For example, as shown in Figure 8, when the frequency offset value is 0, the waveform has no frequency offset, and the duration of a target object is B, corresponding to the second waveform from top to bottom in the figure; when the frequency offset value is N*offset, the frequency has a positive frequency offset, the frequency increases, resulting in a shorter duration of the target object in the time domain, and the duration of the target object is A, corresponding to the first waveform from top to bottom in the figure; when the frequency offset value is -N*offset, the frequency has a negative frequency offset, the frequency decreases, resulting in a longer duration of the target object in the time domain, and the duration of the target object is C. It can be seen that whether a positive frequency offset or a negative frequency offset occurs, the duration of the target object will change.

In addition, by sampling each waveform in FIG8 at a corresponding sampling frequency, a discrete sequence can be obtained, and each discrete sequence can be stored in the first set as a candidate sequence, so that each candidate sequence in the first set corresponds to a frequency offset value and an offset value of the duration of a target object. That is, the first set has a corresponding relationship with the elements in the second set and the third set.

When a frequency offset occurs, whether it is a positive frequency offset or a negative frequency offset, it will change the target object. The duration length and the corresponding candidate sequence will also change, so the correlation value between the synchronization sequence of the reflected signal sent by the Tag received by the Reader and the candidate sequence will change.

Assuming that the Tag has a frequency offset of 2*offset, then in the second set on the Reader side, only the waveform corresponding to the frequency of 2*offset can match the waveform of the Tag with frequency offset, that is, the correlation of these two waveforms has the maximum correlation value (that is, the candidate sequence obtained by sampling the waveform corresponding to the frequency of 2*offset in the second set and the synchronization sequence of the waveform with frequency offset (that is, the reflected signal sent by the Tag) have the maximum correlation value in the correlation sequence obtained by correlating), and the values in the correlation sequence corresponding to the waveforms corresponding to other frequency offset values and the waveform sent by the Tag received by the Reader are all smaller than the above maximum correlation value, as shown in Figure 9.

After the Reader estimates the frequency offset value of the Tag and/or the duration offset value of the target object, the Reader may feed back at least one of the following a) to d) to the Tag:

a) Frequency offset value;

b) a second set [-N*offset, ...., -2*offset, -offset, 0, offset, 2*offset, ..., N*offset] and at least one frequency offset value index F_index;

c) Duration offset value of the target object;

d) a third set [-N*T_offset,…,-2*T_offset,-T_offset,0,T_offset,2*T_offset,…,N*T_offset] and a duration offset value index T_index of at least one target object.

At least one of the above a) to d) may be carried in at least one of the following:

Inventory control signaling;

Query control signaling;

Read control signaling;

Send a control command to query the tag's identity.

When the Tag receives at least one of the above items a) to d) indicated by the Reader, it transmits according to the content indicated by the parameter information within D1. If the Tag does not receive at least one of the above items a) to d) fed back by the Reader, the Tag does not perform frequency offset adjustment and/or transmission time adjustment of the target object, and samples the default time domain resources and frequency domain resources, and transmits within D2. Optionally: The priority of D1 is higher than the priority of D2.

Therefore, an embodiment of the present application can estimate the time domain offset and/or frequency offset of the Tag on the Reader side and indicate the estimation result to the Tag. The Tag adjusts the corresponding frequency domain resources and/or time domain resources according to the parameter information of the Reader, so that in the cellular network, after the Tag is transmitted on the specified frequency resources, the Reader can better schedule and allocate resources and reduce interference between simultaneously sent or received signals.

In addition, it should be noted that the embodiments of the present application can be applicable to two forms: direct communication between Tag and gNB, and communication between UE-assisted Tag and gNB.
