For ease of understanding, some of the matters related to the embodiments of the present application are described below:

1. backscatter communication.

Backscatter communication refers to the transmission of its own information by signal modulation of radio frequency signals in other devices or environments by a backscatter communication device. A backscatter communications device, which may be any of the following:

the backscatter communication device in conventional radio frequency identification (Radio Frequency Identification, RFID), typically a Tag, belongs to a Passive internet of things (Internet of Things, ioT) device (Passive-IoT),

semi-passive (semi-passive) tags, the downlink receiving or uplink reflection of which has a certain amplifying capability;

tag (active tag) with active transmission capability, such terminals may not rely on reflection of an incoming signal to transmit information to a reading device. The reading device may be a base station or a reader.

A simple implementation is that when a tag needs to send a '1', the tag reflects the incoming carrier signal and when the tag needs to send a '0', the tag does not reflect.

The backscatter communication device controls the reflection coefficient Γ of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal, effecting modulation of the signal. Wherein the reflection coefficient of the signal can be characterized as:

Wherein Z is ₀ For the characteristic impedance of the antenna, Z ₁ Is the load impedance. Let the incident signal be S _in (t) the output signal isThus, by reasonably controlling the reflection coefficient, a corresponding amplitude modulation, frequency modulation or phase modulation can be achieved.

2. And (5) checking mode.

In the checking mode, the reading device is required to send a Query instruction (Query) and then a Tag response (Reply) is required, namely, a 16-bit random number is generated to the reading device. And then the reading device sends the sequence to the Tag through an ACK instruction, and the Tag sends related data to the reading device.

3. A backscatter scene.

The reading device sends a continuous wave (continuous wave) and control signaling to the tag, wherein a control (control) type includes at least one of: select, inventory, and access.

4. Beacon (beacon) signal

The purpose of the Beacon signal is: the terminal may move or move out of the coverage range of the low-power consumption wake-up signal because of environmental change in the process of detecting the low-power consumption wake-up signal, so that the wake-up signal sent by the network side device cannot be received. Therefore, one of the functions of the beacon signal is to measure, realize the tracking of the terminal to the signal quality of the network side equipment, and avoid the problem of losing service caused by the terminal moving out of the coverage range of the wake-up signal.

The purpose of the Beacon signal is two: in order to keep synchronization between a low-power Wake-up receiver and an Access Point (AP), a periodic Wake-up receiver beacon (Wake-up Receiver beacon, WUR beacon) signal is adopted in the related art to transmit time information, and a type-dependent control (type dependent control) of a Wake-up receiver beacon media Access control (Medium Access Control, MAC) frame (WUR beacon MAC frame) carries 12 bits of information of [5:16] in 64 bits of a time synchronization function (Synchronization function, TSF) clock (timer), so that after receiving the 12 bits of information, a user updates the TSF timer local to the user according to a time update criterion, thereby achieving the purpose of synchronization with the AP. The transmission cycle of WUR beacon and the offset of the transmission start position, which is the minimum number of TSF time units between two beacon transmissions, are indicated by an operation unit (operation element) of the AP transmission, and the start position is the number of TSF time units offset from TSF 0. When a carrier sense multiple access delay (Carrier Sense Multiple Access deferrals, CSMA delays) occurs, WUR beacon delays transmission in the current period, but is still transmitted in a position determined by the transmission period and transmission start position of WUR beacon in the subsequent period.

Optionally, the WUR beacon signal is also used as a link maintenance signal, and when the WUR beacon signal is not received for a period of time, the STA (Station) must perform WUR search or switch to a mode where the main communication module wakes up. When the wake-up signal configures a discontinuous reception (Discontinuous Reception, DRX) period, that is, wakes up to monitor the wake-up signal according to the DRX period, the wake-up signal is also used as a link-up signal, and during the DRX period when the wake-up signal is not transmitted, the AP may transmit WUR beacon to use as the link-up signal. Wherein the time when the link hold signal is not accepted is determined by the user implementation.

The backscatter communication processing method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

Referring to fig. 2, an embodiment of the present application provides a backscatter communication processing method, as shown in fig. 2, including:

The second device is a device in backscatter communication with said first device, which second device may in particular be understood as a reading device. Optionally, in some embodiments, the second device may be a base station, a terminal, or an integrated access and backhaul (Integrated Access and Backhaul, IAB) node.

Optionally, the first mapping criteria is indicated by a protocol convention, a network side device configuration, or a second device, where the second device is a device in backscatter communication with the first device.

In this embodiment of the present application, each information content in the first mapping rule may correspond to at least two uplink reporting flows. For example, for the time window information, different lengths of the time windows correspond to different uplink reporting flows. For the channel quality information, different channel quality intensities can correspond to different uplink reporting flows.

It should be noted that, in the embodiment of the present application, the second device may continuously or periodically send CW, and after the first device determines the target uplink reporting procedure based on the first information and the first mapping criterion, the second device may actively report the corresponding tag data. For example, the first device may not report on its own initiative when it detects a fire, or not report otherwise. Under the application scene, the second device does not need to count the first device, only needs to further respond according to the information reported by the first device, and further, only needs to select the self-report of the first device, namely, the occurrence of abnormal conditions, such as fire, is illustrated. The second device avoids multiple inventories and the first device avoids frequent responses. And the feedback of the first equipment is effective information, so that the efficiency is greatly improved. The tag data can be understood as business content.

Of course, the application of the scene aiming at active reporting can be further expanded to a scene with small occurrence probability of abnormal conditions such as temperature, motion, vibration, air quality, humidity or radiation, but serious consequences can be generated after the abnormal events occur.

The embodiment of the application acquires first information through first equipment; and the first equipment determines a target uplink reporting flow for the back scattering communication according to the first information and a first mapping criterion. In this way, the first device can actively report based on the determined target uplink reporting flow, so that the timeliness of reporting information is improved. Therefore, the tag data acquisition efficiency is improved.

Optionally, in some embodiments, in a case where the first information includes at least two pieces of information content, and the at least two pieces of information content have corresponding priorities, determining, by the first device, a target uplink reporting procedure for backscatter communication according to the first information and a first mapping criterion includes:

and the first equipment determines the target uplink reporting flow according to target information content and the first mapping criterion, wherein the target information content is the information content with the highest priority in the at least two information contents.

In this embodiment of the present application, it is assumed that the first information includes time window information, channel quality information, and service content, and the priority of the service content is highest, and at this time, the target uplink reporting procedure may be determined based on the service content.

Optionally, in some embodiments, the priority of the information content is indicated by a protocol convention, a network side device configuration, or a second device, the second device being a device in backscatter communication with the first device.

Optionally, in some embodiments, after the first device determines a target uplink reporting procedure for backscatter communications according to the first information and the first mapping criteria, the method further includes:

The first device sends second information to a second device, wherein the second information is used for determining the target uplink reporting flow.

In this embodiment of the present application, the first device may send the second information to the second device, so as to inform the process of reporting the tag information, so that the second device may accurately obtain the tag information reported by the first device. Optionally, the target uplink reporting procedure may be implicitly or explicitly indicated by the second information, and a specific indication manner may be set according to an actual situation, which is not limited herein.

Optionally, in other embodiments, the first device may not indicate the target uplink reporting procedure to the second device, and the second device may determine the target uplink reporting procedure based on the blind detection, so that signaling overhead may be reduced.

Optionally, in some embodiments, the time window information is a reporting time resource configured for the first device by a second device or a network side device, the reporting time resource including at least one of a duration of the reporting time window and a start position of the reporting time window.

The first device determining an importance ranking of the business content;

the first device determines the target uplink reporting procedure based on the importance ranking and the first mapping criteria.

In the embodiment of the application, the association relation of the importance ranks of the business contents can be predefined, and the importance ranks of the business contents to be reported currently are determined according to the association relation, so that the target uplink reporting flow is determined. The target uplink reporting flow is the uplink reporting flow corresponding to the importance ranking of the service content to be reported currently.

Optionally, in some embodiments, the state of the first device is associated with at least one of: whether the first device is an active device, the remaining power of the first device, the temperature of the first device, the degree of emergency the first device reports, and the memory (memory) of the first device.

In this embodiment of the present application, the state partitioning may be performed based on whether the active device is at least one of an active device, a remaining power, a temperature, an emergency degree of reporting, and a storage condition of a memory, and the first mapping rule may include an uplink reporting procedure corresponding to different states. When determining the target uplink reporting procedure based on the state of the first device, the terminal may first determine the current state according to the state partitioning rule, and then determine the target uplink reporting procedure based on the first mapping rule.

Optionally, in some embodiments, the transmission waveform information includes at least one of: modulation scheme, modulation order, and transmission rate.

Optionally, in some embodiments, the first device acquiring the first information includes:

the first device detects a first reference signal;

the first device determines at least one of the coverage information and the channel quality information based on a detection result of the first reference signal.

In this embodiment of the present application, the first reference signal may be a beacon signal, for example, the probability of detecting the beacon signal or correct detection is high, which indicates that the distance is short, the coverage is good, the probability of not detecting the beacon signal or correct detection is too low, which indicates that the distance is long, and the coverage is poor.

Optionally, in some embodiments, the location information is used to represent at least one of: indoor, outdoor, suburban and absolute location coordinates.

the first device receives at least one of the time window information, the channel quality information, and the transmission waveform information from a second device.

Optionally, the uplink reporting procedure associated with the information content included in the first information includes a step (step) reporting procedure, where M is a positive integer.

For example, in some embodiments, the M may be 2 or 4, that is, the uplink reporting procedure associated with the information content included in the first information may include at least one of a 2-step reporting procedure and a 4-step reporting procedure.

Optionally, for the 4-step reporting process, the specific process is as follows:

msg1: the uplink signal is mainly used for marking an uplink report request;

msg2: the downlink signal is mainly used for responding to the uplink report request of the tag by the gNB/reader;

msg3: the uplink signal is mainly used for reporting the tag data;

msg4: the downlink signal is mainly used for confirming the reporting of the tag data by the gNB/reader.

The 4-step reporting process has the following advantages:

1. And the transmission efficiency is improved, and the method is suitable for large data packet transmission. The Msg3 can be transmitted by high-order modulation, a sequence transmission mode of Msg1 is not needed, and the bit efficiency is improved; the length of Msg3 is not limited and a large number of bits can be transmitted at a time.

2. And the probability of failure of data transmission is reduced. If Msg1 adopts sequence transmission, the probability of success of detection at the receiving end when the channel quality is poor can be improved; meanwhile, since the Msg1 only carries a small amount of information, the data packet length is shorter, and the probability of collision caused by simultaneous transmission of a plurality of tags is lower.

Optionally, for the 2-step reporting process, the specific process is as follows:

MsgA: the uplink signal is mainly used for reporting the tag data;

MsgB: the downlink signal is mainly used for confirming the reporting of the tag data by the gNB/reader.

The 4-step reporting process has the following advantages: the method can be used for transmitting the data to be transmitted at one time, occupies less resources, has short transmission delay, and is suitable for the environment with shorter data packet length and better channel quality.

Alternatively, in some embodiments, the reporting procedure may be a contention-based reporting or a non-contention-based reporting.

In contention-based reporting, the preamble is randomly selected in a pool of preambles shared by a tag with other tags, which means that a tag has the risk of selecting the same preamble as another tag, and may then undergo a collision or contention procedure.

In non-contention based random access, a preamble is allocated by a reader or a base station, where the preamble is a random access preamble, and each tag has a dedicated preamble, and no access sequence collision occurs.

Optionally, in some embodiments, the channel quality information includes at least one of: reference signal received power (Reference Signal Received Power, RSRP), reference signal received quality (Reference Signal Received Quality, RSRQ) and signal-to-noise ratio (Signal Noise Ratio, SNR).

For a better understanding of the present application, the following detailed description is provided by way of some examples.
