Description

Method and device for transmitting information

Technical Field

The present application relates to the field of communications, and more particularly, to a method and apparatus for transmitting information.

Background

Passive internet of things is an important research direction in the field of internet of things (internet of things, ioT) at present. In a passive internet of things system, a network device transmits waveforms that continuously contain a high level to a passive tag (tag), which receives and then reflects information to the network device over a reverse link. In the tag reflection link, the tag uses a fixed repetition factor for information reflection.

There are multiple tags within the coverage area of the network device. Then, how to improve the efficiency of identifying tag groups for tags with different distances is a problem to be solved.

Disclosure of Invention

In view of this, the present application provides a method for transmitting information, which can improve the efficiency of identifying tags with different coverage distances.

In a first aspect, a method of transmitting information is provided. The method may be performed, for example, by the first device or by a component (e.g., a circuit, chip, or system-on-chip, etc.) disposed in the first device. The application is not limited in this regard. The first device may be a read-write device, or an auxiliary device, for example.

The method comprises the following steps: the method comprises the steps that first equipment determines first signaling, wherein the first signaling indicates a first repetition factor, and the first repetition factor is used for repeatedly sending information by a tag; and when the tag is read for the nth time, the first device sends the first signaling to at least one first tag, and n is a positive integer.

"read" may also be replaced with "identify" or "inventory".

In the embodiment of the application, the first device sends the first signaling to at least one first tag, and the first signaling indicates the first repetition factor so that the tag repeatedly sends information based on the repetition factor indicated by the first device. Compared with the scheme that the label uses the fixed repetition factor in the prior art, the scheme of the embodiment of the application is more flexible.

The first device may also send a second signaling if there is an inventory-unsuccessful tag in the at least one first tag.

In one possible implementation, optionally, the method further includes: when the tag is read for the n+m time, the first device sends a second signaling to at least one second tag in the at least one first tag, the second signaling indicates a second repetition factor, the value of the second repetition factor is different from the value of the first repetition factor, the at least one second tag is a tag which is not successfully read in the at least one first tag, and m is a positive integer. That is, for an unread successful tag, the first device may re-indicate the repetition factor for the unread successful tag. The tag that has not been successfully read repeatedly transmits information using the re-indicated repetition factor.

Optionally, the value of the second repetition factor is greater than the value of the first repetition factor. That is, for an unread successful tag, the first device may indicate a greater repetition factor for the unread successful tag. The tag which is not read successfully repeatedly sends information by using a larger repetition factor, so that the time efficiency of tag identification is improved, or the inventory process of the tag is quickened.

In the embodiment of the application, for the labels with different coverage distances, the first device optimizes the label inventory process by dynamically indicating the repetition factor. For tags with smaller distances, smaller repetition factors can be utilized for information transmission; for tags farther away, a larger repetition factor is utilized for information transmission. Therefore, the label with a longer coverage distance can be identified, the transmission rate of information sent by the label with a shorter coverage distance can be ensured, and the time efficiency of label identification can be improved, or the inventory process of the label is quickened.

Optionally, the first signaling includes a first indication field, the first indication field is represented by a redundant state of at least one second indication field in the first signaling, and a first value of the first indication field represents the first repetition factor; the second signaling includes a third indication field, the third indication field being represented by a redundant state of at least one fourth indication field in the second signaling, a second value of the third indication field representing the second repetition factor.

The second indication field may be an original indication field in the first signaling (for example, selecting a Target parameter in the signaling), or may be a new indication field, which is not limited. Here, if the second indication field is the original indication field in the first signaling, no new indication field needs to be introduced, i.e. the first indication field may be represented by the redundancy status of the existing indication field, without adding additional overhead.

The fourth indication field may be an original indication field in the second signaling (for example, selecting a Target parameter in the signaling), or may be a new indication field, which is not limited. Here, if the fourth indication field is the original indication field in the first signaling, no new indication field needs to be introduced, i.e. the third indication field may be represented by the redundancy status of the existing indication field, without adding additional overhead.

Optionally, the second signaling is a query signaling in the process of reading the tag, or a selection signaling, or other interactive signaling between the tag and the first device.

Optionally, the first signaling is a query signaling in the process of reading the tag, or a selection signaling, or other interactive signaling between the tag and the first device.

It is understood that the first signaling and the second signaling may be the same type of signaling or different types of signaling, which is not limited in particular. For example, the first signaling is selection signaling and the second signaling is query signaling. For another example, the first signaling and the second signaling are both selection signaling.

In a second aspect, a method of transmitting information is provided. The method may be performed, for example, by the second tag, or may be performed by a component (e.g., a circuit, chip, or system-on-chip, etc.) disposed in the second tag. The application is not limited in this regard.

The method comprises the following steps: the second tag receives first signaling, wherein the first signaling indicates a first repetition factor; the second tag demodulates the first signaling to obtain the first repetition factor; the second tag transmits information using the first repetition factor.

In the embodiment of the application, the second tag acquires the repetition factor indicated by the first device and repeatedly transmits the information based on the repetition factor indicated by the first device. Compared with the scheme that the label uses the fixed repetition factor in the prior art, the scheme of the embodiment of the application is more flexible.

The second tag is an unread tag of the at least one first tag. "read" may also be replaced with "identify" or "inventory".

The tag that was not read successfully may also receive a second signaling sent by the first device.

In one possible implementation, optionally, the method further includes: the second tag receives a second signaling, the second signaling indicates a second repetition factor, the second repetition factor is different from the first repetition factor in value, and m is a positive integer; the second tag demodulates the second signaling to obtain the second repetition factor; the second tag transmits information using the second repetition factor. That is, for an unread successful tag, the first device may re-indicate the repetition factor for the unread successful tag. The tag that has not been successfully read repeatedly transmits information using the re-indicated repetition factor.

Optionally, the second repetition factor has a value greater than the first repetition factor. The tag which is not read successfully repeatedly sends information by using a larger repetition factor, so that the time efficiency of tag identification is improved, or the inventory process of the tag is quickened.

Optionally, the second tag obtains a first value of a first indication domain by demodulating the first indication domain of the first signaling, where the first indication domain is represented by a redundant state of at least one second indication domain in the first signaling; the second tag obtains a second value of a third indication domain by demodulating the third indication domain of the second signaling, and the third indication domain is represented by a redundant state of at least one fourth indication domain in the second signaling.

The method may be performed, for example, by the first device or by a component (e.g., a circuit, chip, or system-on-chip, etc.) disposed in the first device. The application is not limited in this regard. The first device may be a read-write device, or an auxiliary device.

The method comprises the following steps: the first device determining a first repetition factor; and when the tag is read for the nth time, the first equipment repeatedly sends a plurality of first signaling to at least one first tag according to the first repetition factor, and n is a positive integer.

"read" may also be replaced with "identify" or "inventory".

In the embodiment of the application, the first device implicitly indicates the first repetition factor to the tag by repeatedly sending the first signaling to at least one first tag, so that the tag knows the first repetition factor based on a plurality of first signaling, and repeatedly sends information by using the first repetition factor. Compared with the scheme that the label uses the fixed repetition factor in the prior art, the scheme of the embodiment of the application is more flexible. The first aspect is to inform the tag of the first repetition factor by means of direct indication.

In one possible implementation, optionally, the method further includes: and when the label is read for n+m times, the first device repeatedly sends second signaling to at least one second label in the at least one first label according to a second repetition factor, wherein the value of the second repetition factor is different from that of the first repetition factor, the at least one second label is an unsuccessfully-inventory label in the at least one first label, and m is a positive integer. That is, for an unread tag, the first device informs the unread tag of the second repetition factor by transmitting a plurality of second signaling. The tag that was not read successfully repeatedly sends information using a second repetition factor.

Optionally, the value of the second repetition factor is greater than the value of the first repetition factor.

The method comprises the following steps: the second tag receives a plurality of first signaling; the second tag obtains a first repetition factor according to the plurality of first signaling; the second tag transmits information using the first repetition factor.

In the embodiment of the application, the second tag acquires the first repetition factor implicitly notified by the first device and repeatedly transmits information based on the first repetition factor.

The generalized wearable intelligent device includes full functionality, large size, and may not rely on the smart phone to implement complete or partial functionality, such as: smart watches or smart glasses, etc., and focus on only certain types of application functions, and need to be used in combination with other devices, such as smart phones, for example, various smart bracelets, smart jewelry, etc. for physical sign monitoring.

In addition, in the embodiment of the application, the terminal equipment can also be terminal equipment in an internet of things (internet of things, ioT) system, and the IoT is an important component of the development of future information technology, and the main technical characteristics are that the object is connected with the network through a communication technology, so that the man-machine interconnection and the intelligent network of the internet of things are realized.

2, access network: the network access function is provided for the terminal equipment, and the transmission tunnels with different qualities can be used according to the level of the user, the service requirement and the like. The access network may be an access network employing different access technologies. There are two types of current radio access technologies: 3GPP access technologies (e.g., radio access technologies employed in 3G, 4G, or 5G systems) and non-3GPP (non-3 GPP) access technologies. The 3GPP access technology refers to an access technology conforming to the 3GPP standard specification, for example, access network devices in a 5G system are referred to as next generation base station nodes (next generation Node Base station, gNB). The non-3GPP access technology refers to an access technology that does not conform to the 3GPP standard specification, for example, a null interface technology represented by an Access Point (AP) in wireless fidelity (wireless fidelity, wiFi).

An access network implementing access network functions based on wireless communication technology may be referred to as a radio access network (radio access network, RAN). The radio access network can manage radio resources, provide access service for the terminal equipment, and further complete the forwarding of control signals and user data between the terminal and the core network.

The radio access network may include, for example, but is not limited to: a radio network controller (radio network controller, RNC), a Node B (Node B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (home evolved NodeB, or home Node B, HNB), a baseband unit (BBU), an AP in a WiFi system, a radio relay Node, a radio backhaul Node, a transmission point (transmission point, TP), or a transmission reception point (transmission and reception point, TRP), etc., a gNB or a transmission point (TRP or TP) in a 5G (e.g., NR) system, an antenna panel of one or a group (including multiple antenna panels) of base stations in a 5G system, or a network Node constituting a gNB or a transmission point, such as a baseband unit (BBU), or a Distributed Unit (DU), or a base station in a next generation communication 6G system, etc. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the wireless access network equipment.

A read-write device (or reader/writer): refers to a device having reading and writing functions. It is understood that the device in communication with the tag may be, for example, a terminal device, an access network device (e.g., a base station), or a device with read/write functions.

4, label: refers to a device capable of responding to a paging message such as a certain instruction or command. The tag may be an (electronic) tag (radio frequency identification, RFID), i.e. a tag-like or card-like chip with information stored thereon is attached to a person or an article, and is read and identified by electric waves, and may be classified into three types, active, passive and semi-active. The passive tag may also be referred to as a passive internet of things device (the internet of things, IOT) and may be considered a terminal.

Fig. 1 shows an architecture diagram of a communication system to which an embodiment of the present application is applied. As shown in the diagram of fig. 1, architecture 101 includes macro and micro base stations and tags. Communication can be performed between the macro base station and the micro base station. Communication can be performed between the micro base station and the macro base station. The micro base station may send a downlink transmission signal to the tag. The micro base station can also send a downlink excitation signal to the tag, and the tag carries the signal sent to the micro base station on the received downlink excitation signal and reflects the signal to the micro base station.

As shown in the lower diagram of fig. 1, architecture 102 includes macro base stations, micro base stations, auxiliary devices (helpers), and tags. The communication of the tag with the micro base station may be forwarded by the auxiliary device.

Illustratively, the macro base station in fig. 1 may be a gNB and the micro base station may be a Pico base station.

It will be appreciated that fig. 1 described above is merely exemplary and is not intended to limit the present application. For example, the present application can also be applied to other communication scenarios in which reflection communication is enabled.

For ease of understanding, the communication process between the reader and the tag will be described before describing the present application.

1, select Label procedure

The read-write device sends a selection (Select) signaling with which a particular tag or group of tags is selected for inventory and access. The parameters of the selection signaling include Target, action, membank, pointer, length, mask and trunk. The specific meaning of each parameter can be described in the RFID air interface protocol ISO 18000-6C.

2 inventory tag Process

And (1) broadcasting and sending Query (Query) signaling by the read-write equipment, wherein parameters of the Query signaling comprise Q. The tags within the coverage area of the read-write device may be one or more. Each tag within the coverage area may receive the query signaling.

And (2) receiving query signaling sent by the read-write equipment by the label to be inventoried. Based on the parameter Q, the tag is derived from (0, 2 ^Q -1) selecting a random number from the range of values to be loaded into the slot calculator. For tags in the coverage range, selecting tags with non-0 value, and transferring to an arbitration state; the tag with the value of 0 is selected and the response state is entered.

And (3) the tag entering the response state sends a 16-bit random number/pseudo random number (RN 16) to the read-write equipment. Correspondingly, the read-write device receives the RN16 sent by the tag.

And (4) the read-write equipment sends an acknowledgement (ACKnowledgement, ACK) command to the tag which enters the response state, wherein the ACK command comprises the RN16 sent by the tag.

And (5) transferring the confirmed tag to a confirmation state, and sending the PC, the product electronic code (electronic product code, EPC) and the cyclic redundancy check (cyclic redundancy check, CRC) (such as CRC-16) to the read-write equipment to complete the basic information inventory process of the tag.

And (6) the read-write equipment sends a QueryRep signaling or a QueryAdjust signaling. The QueryRep signaling is repeated transmission of the query signaling, and the QueryRep signaling does not change parameters. The query signaling is repeated transmission of the query signaling, and the value of Q can be adjusted.

The value in the slot counter is decremented by 1 each time a QueryRep signaling is received by the tag in the arbitrated state. The tag with a value of 0 in the slot calculator repeats the same reply procedure as described above. When a label in an arbitration state receives a QueryAdjust signaling, the label is in (0, 2) again according to the value of Q ^Q -1) selecting a random number within the range of the value 0 to be loaded into the time slot counter, and then transferring the label with the value 0 to the arbitrated state, and transferring the label with the value 0 to the response state.

When the identified tag receives the QueryRep signaling or QueryAdjust signaling, the inventory flag of the tag is placed in reverse (e.g., from A→B or B→A), and the tag transitions to a ready state, ending the inventory process of the present round.

It will be appreciated that the tag reflects information to the read-write device or transmits a reflected signal, including but not limited to step (3) and step (5) in the tag inventory process described above. The information reflection of the tag adopts a simple linear coding mode, so that the communication anti-interference capability of the tag reflection link is weak, and the coverage distance of the reflection link is severely limited. In addition, in the same time slot, there may be multiple tags reflecting information to the read-write device at the same time. In the case where the reflected signals of a plurality of tags are superimposed to interfere with each other, the read-write apparatus may not be able to correctly demodulate the information reflected by the tags. But if a fixed repetition factor is used for reflection, it is not flexible enough and it is not possible to make tags of different coverage distances identified.

A method of transmitting information according to an embodiment of the present application is described below with reference to fig. 2. In the present application, the first device may be a read-write device, a network device (for example, a micro base station in fig. 1), or a relay node or a cooperative terminal (for example, an auxiliary device in fig. 1). As shown in fig. 2, the method 200 includes:

s210, the first device determines a first signaling, where the first signaling indicates a first repetition factor, and the first repetition factor is used for the tag to repeatedly send information.

Wherein, the information repeatedly sent by the tag includes but is not limited to: the RN16 sent by the tag to the first device; alternatively, the tag sends at least one of PC, EPC and CRC-16 to the read-write device.

Illustratively, the first repetition factor is used for tags to repeatedly reflect information, i.e., reflect the same information multiple times.

The first repetition factor may also be referred to as a spreading factor or a multiplication factor. For example, the tag reflects information using a spreading factor, i.e., multiplies the spreading sequence based on the same information reflected.

The first repetition factor may be a default repetition factor or a smaller value repetition factor, for example.

S220, when the tag is read for the nth time, the first device sends a first signaling to at least one first tag, and n is a positive integer. Correspondingly, at least one first tag receives the first signaling.

The "reading tag" may be equivalently replaced with "inventory tag" or "identification tag", which is not particularly limited by the present application.

The first device is not particularly limited in the embodiment of the present application. For example, if the first device is a network device, S220 includes: the network device directly transmits the first signaling to at least one first tag in a broadcast manner. Or, if the first device is a relay node, S220 includes: the relay node forwards the first signaling sent by the network device to at least one first label. Stated another way, the network device may send the first signaling directly to the at least one first tag, or may send the first signaling to the at least one first tag through the relay node, which is not specifically limited.

In the embodiment of the application, the first device sends the first signaling to at least one first tag, the first signaling indicates the first repetition factor, and the tag repeatedly sends information based on the repetition factor indicated by the first device. Compared with the scheme that the label uses the fixed repetition factor in the prior art, the scheme of the embodiment of the application is more flexible.

After receiving the first signaling, the tag (a certain tag of the at least one first tag) demodulates the first signaling to obtain a first repetition factor, and repeatedly sends information by using the first repetition factor, or uses the first repetition factor (or multiple factor) to reflect by using a spreading sequence with a corresponding multiple length. Illustratively, the tag inventory is performed using a first repeat factor. The process of inventory tag may be referred to in the foregoing description, and will not be repeated here.

After the label inventory operation is performed by the at least one first label by using the first repetition factor, if an uninjuked label exists in the at least one first label, the first device may further send a second signaling to re-indicate the repetition factor for the uninjuked label, so that the uninjured label uses the re-indicated repetition factor to perform label inventory.

As will be appreciated by those skilled in the art, an uninjured tag refers to a tag that does not send at least one of PC, EPC and CRC-16 to the first device, or alternatively, an uninjured tag refers to a tag that does not perform step (5) of the inventory tag process described above. From the perspective of the first device, the tag that was not inventoried successfully is also called a tag that was not read successfully.

For convenience of description, the present application introduces a second tag to refer to a tag that has not been successfully read. At least one second tag exists in the at least one first tag. It will be appreciated that the terms "first tag" and "second tag" are also introduced to distinguish whether a tag is successfully read, and are not limiting to the application.

For the first device, the first device may learn that the tags that were not successfully read, for example, the first device selects 1000 tags, but inventory successful tags are 100 tags, and then the remaining 900 tags are not successfully read.

Optionally, the method 200 further includes: s230, when the tag is read for the n+m times, the first device sends a second signaling to at least one second tag in the at least one first tag, the second signaling indicates a second repetition factor, the value of the second repetition factor is different from the value of the first repetition factor, the at least one second tag is an unsuccessfully-inventoried tag in the at least one first tag, and m is a positive integer. Correspondingly, at least one second tag receives the second signaling. Demodulating the second signaling by the second tag to obtain a second repetition factor; the information is repeatedly transmitted using the second repetition factor. m may be 1, or an integer greater than 1.

Wherein the value of the second repetition factor is different from the value of the first repetition factor.

In particular, the first device may re-indicate the repetition factor (such as the second repetition factor) for at least one second tag that failed to inventory. If the tag is not successfully inventoried using the first repetition factor, then at least one second tag that is not successfully inventoried sends information using the second repetition factor in anticipation of successful inventory of the tag or identification (or reading) by the network device.

Illustratively, assume that n has a value of 1, i.e., the first device instructs the population of tags to transmit information using a first repetition factor when the tags are first read. Assuming that m has a value of 1, i.e., in the case of reading a tag for the second time, for a tag that is not inventory successful (or not read successful) in the tag group, the first device may indicate a second repetition factor to the tag that is not inventory successful (or not read successful) so that the tag that is not inventory successful (or not read successful) sends information using the second repetition factor.

Optionally, the value of the second repetition factor is greater than the value of the first repetition factor. That is, for an unread successful tag, the first device may indicate a greater repetition factor for the unread successful tag. Tags that are not read successfully repeat the information using a larger repetition factor. Here, the "larger repetition factor" is relative to the repetition factor indicated by the first device at the nth time of reading the tag, i.e., the repetition factor indicated by the first device at the n+mth time of reading the tag is larger than the repetition factor indicated by the first device in the case of reading the tag at the nth time.

It will be appreciated that if the tag has not been successfully read, the first device may again indicate a greater repetition factor to the tag that was not successfully read until the tag is successfully read or the repetition factor reaches a maximum limit. Stated another way, the first device may indicate the repetition factor to the tag that was not read successfully in order from small to large until the tag is read successfully or the repetition factor reaches a maximum limit. The maximum limit of the repetition factor is reached, and the application is not limited in particular. For example, the maximum limit is 32.

The first repetition factor and/or the second repetition factor of the embodiments of the present application may be represented by a value of an indication field in the signaling. For example, the first signaling includes a first indication field, the first indication field is represented by a redundant state of at least one second indication field in the first signaling, and a first value of the first indication field represents the first repetition factor; the second signaling includes a third indication field, the third indication field being represented by a redundant state of at least one fourth indication field in the second signaling, a second value of the third indication field representing the second repetition factor. The first value is different from the second value.

The first indication field may be represented by a redundant state of at least one second indication field in the first signaling. The second indication field may be an original indication field in the first signaling (for example, selecting a Target parameter in the signaling), or may be a new indication field, which is not limited. For example, the first indication field may be identified by a redundant state of the indication field (or indication fields) in the first signaling. Here, if the second indication field is the original indication field in the first signaling, no new indication field needs to be introduced, i.e. the first indication field may be represented by the redundancy status of the existing indication field, without adding additional overhead.

It will be appreciated that the first indication field may be a reserved bit in the first signaling, or a newly added bit, which is not particularly limited.

Similarly, the third indication field may be represented by a redundant state of at least one fourth indication field in the second signaling. The fourth indication field may be an original indication field in the second signaling (for example, selecting the Target parameter in the signaling), or may be a new indication field, which is not limited. For example, the third indication field may be identified by a redundant status of the indication field (or indication fields) in the second signaling. Here, if the fourth indication field is the original indication field in the first signaling, no new indication field needs to be introduced, i.e. the third indication field may be represented by the redundancy status of the existing indication field, without adding additional overhead.

It will be appreciated that the third indication field may be a reserved bit in the second signaling, or a newly added bit, which is not particularly limited.

For the tag, after receiving the first signaling, the tag may obtain the first repetition factor by demodulating the first indication field of the first signaling. Similarly, after receiving the second signaling, the tag may obtain the second repetition factor by demodulating the third indication field of the second signaling.

The form of the first signaling and/or the second signaling is not particularly limited in the present application. The first signaling and/or the second signaling may be existing signaling or newly defined signaling.

Alternatively, the first signaling may be a query signaling during reading of the tag, or a selection signaling, or other interaction signaling between the tag and the first device. The second signaling may be query signaling during reading of the tag, or selection signaling, or other interactive signaling between the tag and the first device.

For example, the repetition factor may be indicated with 3 reserved bits in the target parameter in the selection signaling, or the multiple factor may be indicated by adding additional bits in the selection signaling.

For example, the repetition factor may be indicated by a reserved bit in the query signaling, or the repetition factor may be indicated by adding an additional bit in the query signaling. For example, 3 reserved bits in the target parameter in the selection signaling indicate the repetition factor, and when the value of the reserved bits is 101, the value of the multiple factor is 8; when the value of the reserved bit is 110, the value of the multiple factor is 16; when the value of the reserved bit is 111, the value of the multiple factor is 32. However, the selection signaling may have an original function, i.e. for selecting at least one tag.

It will be appreciated that the above examples are for ease of understanding only, and the application is not limited thereto.

It is further understood that the first signaling and the second signaling may be the same type of signaling or different types of signaling, which is not limited in particular. For example, the first signaling is selection signaling and the second signaling is query signaling. For another example, the first signaling and the second signaling are both selection signaling.

The specific steps of taking the first device as a network device, the first signaling as a selection signaling and the second signaling as the selection signaling as an illustration of the disk storage label are as follows:

step 1, the network device sends a selection signaling to the plurality of tags, and indicates that the first repetition factor is 8 through a target parameter of the selection signaling. After receiving the selection signaling, the plurality of tags demodulate the selection signaling to obtain that the first repetition factor is 8.

And step 2, the network equipment sends a query signaling and starts a first wheel disc label storing process. Multiple tags repeat the reflection information 8 times. After the first wheel disc label storing process is finished, labels which are not successfully stored and labels which are successfully stored exist. Wherein a label with successful inventory will flag the position of the label.

And 3, resetting a target parameter in the selection signaling by the network equipment in the process of storing the label by the first wheel disc for the label which is not successfully stored in the process of storing the label by the first wheel disc, and sending the selection signaling after resetting the target parameter to the label which is not successfully stored in the process of storing the label by the first wheel disc, wherein the target parameter indicates that the second repetition factor is 16. Multiple tags reflect 16 messages, or repeatedly transmit 16 messages.

And 4, for the label which is not successfully inventoried in the label storage process of the second wheel disc, the network equipment can continue to increase the repetition factor until the repetition factor reaches the maximum limit, and the inventory process of the label is ended.

It will be appreciated that steps 1-4 described above are only exemplary, and the application is not limited thereto.

For the inventory process of the label group, the first device continuously and dynamically indicates the repetition factor (or dynamically adjusts the repetition factor) through signaling, so that the inventory process of labels with different coverage distances can be effectively applied, and the identification efficiency of the labels with different coverage distances is improved.

The application also provides a method for transmitting information. The first device implicitly indicates the repetition factor to the tag. A method of transmitting information according to an embodiment of the present application is described below with reference to fig. 3. In the present application, the first device may be a read-write device, a network device (for example, a micro base station in fig. 1), or a relay node or a cooperative terminal (for example, an auxiliary device in fig. 1).

As shown in fig. 3, the method 300 includes:

s310, the first device determines a first repetition factor.

And S320, when the tag is read for the nth time, the first equipment repeatedly sends a plurality of first signaling to at least one first tag according to the first repetition factor, and n is a positive integer. Correspondingly, at least one first tag receives a plurality of first signaling.

The relevant description of the "read tag" and the "first device" may refer to the explanation in the foregoing method 200, and for brevity, will not be repeated here.

How many first signaling is sent by the first device, the tag considers the repetition factor to be what. For example, the first device sends 4 first signaling, and the tag may learn that the first repetition factor has a value of 4.

In the embodiment of the application, the first device implicitly informs the tag of the first repetition factor by repeatedly sending the first signaling, so that the tag repeatedly sends information based on the first repetition factor implicitly informed by the first device. Compared with the scheme that the label uses the fixed repetition factor in the prior art, the scheme of the embodiment of the application is more flexible.

The tag (a certain tag of the at least one first tag) may obtain a first repetition factor after receiving the first signaling repeatedly sent by the first device; the information is transmitted using the first repetition factor or reflected with a spreading sequence of a corresponding multiple length using the first repetition factor (or multiple factor). Illustratively, the tag inventory uses a first repetition factor. The process of inventory tag may be referred to in the foregoing description, and will not be repeated here.

Similarly, after the label inventory operation is performed by using the first repetition factor, if there is an uninformed label, the first device may further repeatedly send a second signaling to re-indicate the repetition factor for the uninformed label, so that the uninformed label inventory is performed by using the re-indicated repetition factor. Optionally, the method 300 further includes: and when the label is read for n+m times, the first device repeatedly sends second signaling to at least one second label in the at least one first label according to a second repetition factor, wherein the value of the second repetition factor is different from that of the first repetition factor, the at least one second label is an unsuccessfully-inventory label in the at least one first label, and m is a positive integer.

The description of the first label, the second label, and the label that was not successfully inventoried may be referred to the description of the method 200 above, and will not be repeated here for brevity.

At least one second tag that is not inventoried successfully may obtain a second repetition factor by receiving a second signaling repeatedly sent by the first device. At least one second tag that was not inventoried successfully sends information using a second repetition factor in the hope that the tag was inventoried successfully or identified by the network device.

Alternatively, the first signaling may be a query signaling during reading of the tag, or a selection signaling.

Alternatively, the second signaling may be a query signaling during reading of the tag, or a selection signaling.

The description of the first signaling and the second signaling may refer to the description of the method 200, and is not repeated herein for brevity.
