[0106] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0107] In some embodiments, with the development of communication technology, tag devices and read-write devices in the Internet of Things are no longer limited to conventional tags and readers (also called readers). For example, in some embodiments, the read-write device can be a network device, and the tag can be a tag terminal. In some embodiments, the read-write device can be a read-write terminal, and the tag device can be a tag terminal. The above-mentioned read-write terminals and tag terminals can be traditional terminals or reduced capability (Redcap) terminals, and the present disclosure does not limit this.

[0108] In the scenario where traditional readers and writers of the passive Internet of Things are used to take inventory of tags, the readers and writers are generally handheld devices, while the tags are generally fixed tags. The inventory is performed manually by pointing the reader and writer at the tags. During this process, the reader and writer only performs an inventory operation on one tag at a time.

[0109] However, in scenarios where the read / write device is a network device or terminal and the tag device is a terminal, the signal coverage range of the network device and the terminal is much larger than the coverage range of the traditional reader / writer. If the read / write device still only performs inventory operations on one tag device each time, it will cause a large waste of the communication capabilities of the read / write device.

[0110] FIG2 is an interactive schematic diagram showing a method for receiving scheduling information according to an embodiment of the present disclosure.

[0111] As shown in FIG2 , the scheduling information receiving method includes the following steps:

[0112] Step S201: The reading and writing device determines a first coverage level of a first tag device.

[0113] Step S202: The reader / writer device sends scheduling information corresponding to the first coverage level to the first tag device.

[0114] In some embodiments, the first tag device belongs to a first tag device group.

[0115] In some embodiments, the first tag device group corresponds to the first coverage level, that is, the tag devices in the first tag device group have the same coverage level, which is the first coverage level.

[0116] In some embodiments, the reading and writing device sends scheduling information to the first tag device group.

[0117] In some embodiments, the reading and writing device sends scheduling information to at least one tag device group.

[0118] In some embodiments, the read-write device can perform an inventory operation on the tag device. Since the inventory operation requires the tag device to send information to the read-write device, the read-write device can send scheduling information to at least one tag device that needs to be inventoried. The scheduling information can be used to schedule the first tag device for uplink transmission.

[0119] For example, the content of the uplink transmission includes at least one of the following: information sensed by the first tag device, and identity information of the first tag device, wherein the identity information includes but is not limited to an Electronic Product Code (EPC).

[0120] According to an embodiment of the present disclosure, the read-write device can send scheduling information to at least one tag device group. A tag device group can contain one or more tag devices. Accordingly, the read-write device can schedule multiple tag devices at a time, thereby improving the inventory efficiency of the read-write device on the tag devices.

[0121] Within the coverage range of the read-write device, the positions of different tag devices may be different. Based on the different positions, the communication quality between the tag device and the read-write device may be different. The communication quality can be characterized by the coverage level. Multiple tag devices with the same coverage level have the same or similar communication quality as the tag device.

[0122] Since the scheduling information required for multiple tag devices with the same coverage level to communicate with the read-write device is generally the same, in the embodiment of the present disclosure, for the tag device group corresponding to the tag devices with the same coverage level, the read-write device can determine that the tag devices in the tag device group need the same scheduling information, and then send the same scheduling information to the tag devices in the tag device group, so as to meet the needs of communication between the tag device and the read-write device, and it is conducive to simplifying the operation of the reader device sending the scheduling information.

[0123] In some embodiments, the reading and writing device sends the same scheduling information to multiple tag devices in a tag device group. The scheduling information can be sent to multiple tag devices at one time in a groupcast or multicast manner, or the scheduling information can be sent to each tag device separately in a unicast manner. The present disclosure does not limit the sending method.

[0124] In some embodiments, the scheduling information includes at least one of the following: the number of channels; the number of sub-channels; the number of frequency points; the number of time domain units; the number of repetitions; and the first coverage level.

[0125] For example, the scheduling information may include the channel number, that is, the number of channels. For example, if the channel number is 2, the tag device can perform uplink transmission to the reader / writer device on 2 channels.

[0126] For example, the scheduling information may include the number of sub-channels, that is, the number of sub-channels in a channel. For example, if the number of sub-channels is 3, the tag device may perform uplink transmission to the reader / writer device on the three sub-channels.

[0127] For example, the scheduling information may include the frequency number, that is, the number of frequency points, where the frequency point can also be called the Absolute Radio-Frequency Channel Number (ARFCN). For example, if the frequency point number is 2, the tag device can perform uplink transmission to the reader / writer device on 2 frequency points.

[0128] For example, the scheduling information may include the number of time domain units, i.e., the number of time domain units, where a time domain unit includes at least one of the following: a frame, a sub-frame, a time slot, or a symbol. Taking a time slot as an example, if the number of time domain units is 5, the tag device can perform uplink transmission to the reader / writer device for 5 time slots.

[0129] For example, the scheduling information may include the number of repeated transmissions. For example, if the number of repeated transmissions is 4, the tag device repeats the uplink transmission to the reader / writer device 4 times.

[0130] In some embodiments, since the coverage levels corresponding to different tag device groups may be different, the scheduling information corresponding to each tag device group may also be different. Therefore, for the scheduling information sent by the reading and writing device to the tag device group, it is necessary for the tag devices in the tag device group to clearly determine whether the received scheduling information is the scheduling information corresponding to their own coverage level, that is, whether the coverage level corresponding to the scheduling information is the same as the coverage level of the tag device itself.

[0131] Therefore, in an embodiment of the present disclosure, the scheduling information may also include a coverage level, and the tag device may compare the coverage level in the scheduling information with its own coverage level, wherein, if the coverage level in the scheduling information is the same as its own coverage level, the tag device performs uplink transmission based on the scheduling information; if the coverage level in the scheduling information is different from its own coverage level, the tag device does not perform uplink transmission based on the scheduling information.

[0132] For example, the scheduling information sent by the reading and writing device to the first tag device may include the first coverage level. Since the coverage level of the first tag device is the first coverage level, the first tag device can determine that the coverage level in the scheduling information is the same as its own coverage level, and thus perform uplink transmission based on the received scheduling information.

[0133] For example, the read / write device may indicate N coverage levels, and the scheduling information bits may be used for one coverage level among N coverage levels as the coverage level of scheduling information.

[0134] In some embodiments, the type of tag device includes but is not limited to Type A, Type B, and Type C.

[0135] Type A tags do not require energy storage; Type B tags can store energy and determine coverage levels based on the amount of stored energy; Type C tags have independent power and can generate device signals. Type A and Type B tags can also send signals to the reader / writer. For example, they cannot generate signals independently, but instead reflect signals from the reader / writer back to the reader / writer.

[0136] In some embodiments, the scheduling information receiving method includes: sending first information to the read-write device, wherein the first information is used by the read-write device to determine a first coverage level of the first tag device.

[0137] For example, the coverage level of the tag device itself can be determined by the tag device, and then the tag device can send the first information to the reader / writer device so that the reader / writer device determines the coverage level of the tag device.

[0138] In some embodiments, the first information includes at least one of the following: a random number, a sequence.

[0139] For example, the tag device and the reader / writer device may store an association between random number ranges and coverage levels. When the first tag device determines that its coverage level is the first coverage level, it can determine the random number range corresponding to the first coverage level based on the association, and then determine a random number within the random number range as the first information to be sent to the reader / writer device. After receiving the random number, the reader / writer device can determine the random number range within which the random number falls, and then determine that the random number range corresponds to the first coverage level based on the stored association.

[0140] For example, the tag device and the reader / writer device may store an association between sequences and coverage levels. When the first tag device determines that its coverage level is the first coverage level, it may determine the sequence corresponding to the first coverage level based on the association, and then send the sequence as the first information to the reader / writer device. After receiving the sequence, the reader / writer device may determine that the sequence corresponds to the first coverage level based on the stored association.

[0141] In some embodiments, the type of sequence includes at least one of the following: a bit sequence, a pilot sequence.

[0142] In some embodiments, the resource of the first information includes: a Physical Random Access Channel (PRACH) resource.

[0143] For example, the tag device and the reader / writer device may store an association relationship between PRACH resources and coverage levels. When the first tag device determines that its own coverage level is the first coverage level, it may determine the PRACH resource corresponding to the first coverage level based on the association relationship, and then send the first information to the reader / writer device using the PRACH resource. After the reader / writer device receives the first information on the PRACH resource, it may determine that the PRACH resource corresponds to the first coverage level based on the stored association relationship.

[0144] The following describes several embodiments to illustrate how to determine the coverage level of a tag device.

[0145] In some embodiments, the scheduling information receiving method further includes: receiving first reference information sent by the read / write device; and determining the first coverage level according to the first reference information.

[0146] The reader / writer device may send first reference information to the tag device. For example, the first reference information includes at least one of the following: a reference signal; a synchronization broadcast signal block (SS (Synchronization Signal) and PBCH (Physical downlink Broadcast Channel) Block, SSB); a sequence; or a pilot.

[0147] Taking the first reference information including SSB as an example, after receiving the SSB, the reading and writing device can determine the signal quality of the received SSB. For example, the signal quality can be represented by the reference signal receiving power (RSRP).

[0148] The first tag device can store at least one RSRP threshold (for example, it can be configured by the read / write device, or it can be agreed upon by the protocol). For example, two RSRP thresholds are stored, namely RSRP#1 and RSRP#2, where RSRP#1 is less than RSRP#2. For example, when it is determined that the RSRP of the received SSB is less than RSRP#1, the first tag device can determine that the first coverage level is L#1. When it is determined that the RSRP of the received SSB is greater than or equal to RSRP#1 and less than RSRP#2, the first tag device can determine that the first coverage level is L#2. When it is determined that the RSRP of the received SSB is greater than or equal to RSRP#3, the first tag device can determine that the first coverage level is L#3.

[0149] Taking the first reference information including a sequence as an example, after receiving the sequence, the read / write device can determine at least one of the following results: an average value of high levels in the sequence, a sum of high levels in the sequence, and a received signal strength indication (RSSI) of the sequence.

[0150] In some embodiments, RSSI can be determined based on at least one of the following: the sum of the received signal strengths of the sequence within the first time length, the average of the received signal strengths of the sequence within the first time length, the first time length can be configured for the read / write device, or agreed upon by the protocol, and the present disclosure does not limit this.

[0151] Taking the determination result including RSSI as an example, the first tag device can store at least one RSSI threshold value (for example, it can be configured by the read / write device, or it can be agreed upon by the protocol), and taking the storage of two RSSI threshold values ​​as an example, RSSI#1 and RSSI#2, respectively, where RSSI#1 is less than RSSI#2. For example, when it is determined that the RSSI of the received sequence is less than RSSI#1, the first tag device can determine that the first coverage level is L#1; when it is determined that the RSSI of the received sequence is greater than or equal to RSSI#1 and less than RSSI#2, the first tag device can determine that the first coverage level is L#2; when it is determined that the RSSI of the received sequence is greater than or equal to RSSI#3, the first tag device can determine that the first coverage level is L#3.

[0152] FIG3 is a schematic diagram showing a sequence according to an embodiment of the present disclosure.

[0153] In some embodiments, the sequence comprises at least one of:

[0154] A first sequence, wherein the first sequence is also used by the first tag device to determine that the read / write device is about to send information;

[0155] A second sequence, wherein the second sequence is located before or after the first sequence, and the signal corresponding to each clock in the second sequence is the same.

[0156] In some embodiments, before taking inventory of the tag device, the read / write device can perform selection and challenge operations on the tag, wherein the selection operation is used to select one or more tags in the tag group for inventory, and the challenge operation is used to query the encryption and authentication type of the tag, and then the inventory operation can be performed on the tags that pass the challenge operation.

[0157] In some embodiments, an inventory operation may begin with the reader / writer device sending a query command to the tag device and terminate with the reader / writer device sending a query command again, or terminate with another selection or challenge operation. Before sending a query command to the tag device, the reader / writer device may first send a first sequence to the tag device, so that the tag device determines that the reader / writer device will send a query command after the first sequence.

[0158] In an embodiment of the present disclosure, when the first reference information includes a sequence, the sequence may be only the first sequence, or the sequence may be the first sequence and the second sequence.

[0159] As shown in FIG3 , since the number of clock signals in the first sequence is relatively small, the results determined based only on the first sequence, such as the average value of the high level in the sequence (for example, the clock signal corresponding to the value 1 in FIG3 ), the average value of the high level in the sequence, and the RSSI of the sequence, may have low accuracy. Therefore, the reader / writer device may additionally send a second sequence before or after the first sequence, and the signal corresponding to each clock in the second sequence is the same (for example, the second sequence in FIG3 contains 4 low-level clock signals). Accordingly, the results determined by the tag device based on the first sequence and the second sequence are relatively accurate, which is conducive to ensuring that the tag device accurately determines its own coverage level based on the obtained results.

[0160] It should be noted that, as shown in FIG3 , a meaningless signal “v” may be provided between the second sequence and the first sequence to indicate the end of the second sequence and the start of the first sequence.

[0161] In some embodiments, the scheduling information receiving method further includes: receiving indication information sent by the reading and writing device, wherein the indication information is used to indicate the coverage level of the tag device.

[0162] In some embodiments, the tag device cannot determine its own coverage level. For example, the tag device is of Type A (but not limited to this). In this case, the reader / writer device can send indication information to the tag device, and the tag device can determine its own coverage level based on the indication information.

[0163] For example, the read / write device may indicate N coverage levels, and the indication information sent by the read / write device to the tag device may include: bits, used to indicate one of N coverage levels to the tag device.

[0164] In some embodiments, the scheduling information receiving method further includes: sending second reference information to the read-write device, wherein the second reference information is used by the read-write device to determine the first coverage level of the first tag device.

[0165] In some embodiments, the tag device may send second reference information to the read-write device. The second reference information may be information generated autonomously by the tag device, or information sent by the read-write device to the tag device and reflected to the read-write device via the tag device.

[0166] For example, the second reference information may be a sequence, which may include at least one of a first sequence and a second sequence. Because the first sequence contains a relatively small number of clock signals, results determined solely based on the first sequence, such as the average value of high levels in the sequence, the average value of high levels in the sequence, or the RSSI of the sequence, may be less accurate. Therefore, the tag device may additionally transmit a second sequence before or after the first sequence, with the signals corresponding to each clock in the second sequence being identical. Consequently, the results determined by the reader / writer based on the first and second sequences are relatively accurate, helping to ensure that the tag device accurately determines the tag's coverage level based on the obtained results.

[0167] In some embodiments, configuration information related to quantity, such as the number of sub-channels, the number of frequency points, the number of time domain units, and the number of repeated transmissions, may be negatively correlated with the coverage level.

[0168] For example, using the number of repeated transmissions and the three coverage levels L#1 to L#3 as an example, for a tag device with coverage level L#1, the number of repeated transmissions can be N1; for a tag device with coverage level L#2, the number of repeated transmissions can be N2; and for a tag device with coverage level L#3, the number of repeated transmissions can be N3, where N1>N2>N3. Because tag devices with lower coverage levels have relatively poor communication performance with the reader / writer, configuring a relatively high number of repeated transmissions for these tag devices helps ensure the quality of communication between the tag device and the reader / writer.

[0169] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 to S202. For example, step 201 may be implemented as an independent embodiment, step 202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.

[0170] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0171] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0172] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0173] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 .
