[0105] In a communication system, in order to save power and reduce device complexity, a new type of Internet of Things (IOT) device or Ambient Internet of Things (Ambient IOT or A-IOT) device is introduced. For example, the new type of IOT device needs to collect radio waves sent by the surrounding environment or surrounding devices to obtain energy to drive itself to work. Therefore, before obtaining energy, the new type of IOT device is usually in an "off" state, i.e., an off-network state. Therefore, the communication system needs to support a data communication mode with shorter transmission time, lower memory consumption, and more convenient terminal management to complete the data communication process as soon as possible.

[0106] In some embodiments, the present disclosure implements a wireless communication design based on ambient energy devices (which can also be referred to as IOT devices or Ambient IOT devices, i.e., second devices herein) for communication based on backscattering technology. Optionally, the above-mentioned IOT devices or Ambient IOT devices (also referred to as Ambient IOT devices or A-IOT devices) can be applied to various different communication architectures in a communication system. For example, taking an A-IOT device as an example, FIGS. 2A-2E are schematic diagrams of an A-IOT device communicating with a network device and / or a terminal according to embodiments of the present disclosure. Optionally, as shown in FIG. 2A, the A-IOT device (i.e., the Ambient IOT device in FIG. 2A) can directly receive and transmit data or signals with a network device (such as a base station (BS)).

[0110] Optionally, as shown in FIG. 2E, the A-IOT device and the terminal (also known as user equipment (UE)) can directly receive and send data, and the terminal can be responsible for collecting data of the A-IOT device and forwarding the collected data to the network device.

[0111] In the related art, the power storage of the passive Internet of Things device is limited, and continuous command listening will cause power consumption and even power failure, and the charging process will affect the command transmission of the device, so how to reduce the power consumption of the device while maintaining the availability of the device has become a problem to be solved.

[0112] To this end, the embodiments of the present disclosure provide a communication method and device, which can solve the problem of how to instruct the Internet of Things device to enter a specific power state in the Internet of Things scenario, and can make the device support discontinuous reception, reduce the impact on command transmission while ensuring the power of the device.

For example, the value of the first indication information in the first command is a second value, and the second device 102 can determine that the first command includes multiple first identifiers. For example, the value of the first indication information in the first command is a third value, and the second device 102 can determine that the first command includes the second identifier. For example, the value of the first indication information in the first command is a fourth value, and the second device 102 can determine that the first command does not include any identifier or that the first command includes a special value.

[0145] In some embodiments, the second device 102 can determine, according to the second indication information in the first command (e.g., according to the value of the second indication information in the first command), whether the target state is specifically the first state, or the second state, or the third state. For example, the value of the second indication information in the first command is a fifth value, and the second device 102 can determine that the target state is the first state. For example, the value of the second indication information in the first command is a sixth value, and the second device 102 can determine that the target state is the second state. For example, the value of the second indication information in the first command is a seventh value, and the second device 102 can determine that the target state is the third state.

[0146] In some embodiments, the second device 102 can determine to perform the first action according to its own device identity and the first command. For example, if the first command includes one first identity, and the second device 102 receives the first command, if the one first identity included in the first command is the same as (or consistent with) the device identity of the second device 102, the second device 102 can perform the first action, which is to enter the target state and / or to be in the target state for the first time duration, i.e., if the one first identity included in the first command is the same as (or consistent with) the device identity of the second device 102, the second device 102 determines that it can enter the target state and / or be in the target state for the first time duration; if the one first identity included in the first command is different from (or inconsistent with) the device identity of the second device 102, the second device 102 can perform the first action, which is to keep the current state, i.e., the second device 102 determines that it cannot enter the target state but keep the current state. For another example, if the first command includes multiple first identities, and the second device 102 receives the first command, if the multiple first identities included in the first command include the device identity of the second device 102 (or in other words, the multiple first identities include a first identity that is the same as the device identity of the second device 102), the second device 102 performs the first action, which is to enter the target state and / or to be in the target state for the first time duration, i.e., the second device 102 determines that it can enter the target state and / or be in the target state for the first time duration; if the multiple first identities included in the first command do not include the device identity of the second device 102 (or in other words, the multiple first identities do not include a first identity that is the same as the device identity of the second device 102), the second device 102 can perform the first action, which is to keep the current state, i.e., the second device 102 determines that it cannot enter the target state but keep the current state.For example, if the second device 102 receives the first command including the second identifier, and the second identifier included in the first command is the same as or consistent with the group identifier of the second device 102 (i.e., the group identifier of the second device group to which the second device 102 belongs), the second device 102 performs the first action, which is to enter the target state and / or to be in the target state for the first duration, i.e., the second device 102 can determine that it can enter the target state and / or be in the target state for the first duration. If the second identifier included in the first command is not the same as or consistent with the group identifier of the second device 102 (i.e., the group identifier of the second device group to which the second device 102 belongs), the second device 102 can perform the first action, which is to keep the current state, i.e., the second device 102 can determine that it cannot enter the target state but keep the current state. For example, if the first command does not include any identifier, and the second device 102 receives the first command, the second device 102 performs the first action, which is to enter the target state and / or to be in the target state for the first duration, i.e., the second device 102 can determine that it can enter the target state and / or be in the target state for the first duration. For example, if the first command includes a special value (e.g., all), and the second device 102 receives the first command, the second device 102 performs the first action, which is to enter the target state and / or to be in the target state for the first duration, i.e., the second device 102 can determine that it can enter the target state and / or be in the target state for the first duration.

[0147] In some embodiments, the second device 102 receives the first command sent by the first device 101, and the second device 102 can determine, according to the first command, the second indication information in the first command, that the second device 102 performs the first action, which can include any of the following: keeping the current state; entering the target state and / or being in the target state for the first duration. In some embodiments, the second device 102 receives the first command sent by the first device 101, and the second device 102 can determine, according to the first command, the first indication information and the second indication information in the first command, that the second device 102 performs the first action.

[0152] Optionally, in some embodiments, as shown in FIG. 3A, the method can include step S3103.

[0153] Step S3103, the second device 102 enters the target state and the duration of keeping the target state is the first duration.

[0154] In some embodiments, the second device 102 determines that it can enter the target state and the duration of being in the target state, or that the second device 102 determines that it can perform the first action, which is to enter the target state and / or the duration of being in the target state is the first duration, then the second device 102 enters the target state and remains in the target state for the first duration. For example, the target state can be the first state, the second device 102 determines that it can enter the first state and the duration of being in the first state, then the second device 102 enters the first state and remains in the first state for the first duration. For example, the target state can be the second state, the second device 102 determines that it can enter the second state and the duration of being in the second state, then the second device 102 enters the second state and remains in the second state for the first duration. For example, the target state can be the third state, the second device 102 determines that it can enter the third state and the duration of being in the third state, then the second device 102 enters the third state and remains in the third state for the first duration.

[0155] For example, the second device 102 determines that it can enter the first state, and in the case that the second device 102 is in the first state, the second device 102 can both send and receive commands (or information or signals). For example, the second device 102 determines that it can enter the second state, and in the case that the second device 102 is in the second state, the second device 102 can neither send nor receive commands (or information or signals). For example, the second device 102 determines that it can enter the third state, and in the case that the second device 102 is in the third state, the second device 102 can send (or information or signals) but cannot receive commands (or information or signals).

[0156] In some embodiments, the start time of the first duration can be the start of the time slot or the end of the time slot in which the second device 102 receives the first command. That is, the duration of the second device 102 being in the target state after receiving the first command can be the first duration after the start of the time slot in which the second device 102 receives the first command. Alternatively, the duration of the second device 102 being in the target state after receiving the first command can be the first duration after the end of the time slot in which the second device 102 receives the first command.

[0157] It should be noted that in some embodiments, step S3103 can be performed in the case that the second device 102 determines that it can enter the target state (or that the second device 102 determines to perform the first action, which is to enter the target state and / or the duration of being in the target state is the first duration).

[0158] Optionally, in some embodiments, as shown in FIG. 3A, the method can comprise step S3104.

[0159] Step S3104, when the first time length ends, the second device 102 exits the target state.

[0160] For example, the second device 102 enters the first state and keeps the first state for the first time length, when the first time length ends, the second device 102 exits the first state and enters the second state or the third state. For example, the second device 102 enters the second state and keeps the second state for the first time length, when the first time length ends, the second device 102 exits the second state and enters the first state or the third state. For example, the second device 102 enters the third state and keeps the third state for the first time length, when the first time length ends, the second device 102 exits the third state and enters the first state or the second state.

[0161] It is worth noting that in some embodiments, the first device 101 can directly instruct the second device 102 to enter a certain target state. For example, the first device 101 can instruct the second device 102 to enter a target state such as ON, OFF, SLEEP, etc. based on specific business. The first device 101 of the present disclosure can determine to instruct the second device to enter the OFF / SLEEP state without the first transmission (i.e. the transmission from the first device to the second device), so as to save the power of the second device as much as possible, reduce the number of charging and discharging, and improve the working performance of the second device. In addition, the first device can determine to instruct the second device to enter the ON state in the case that there is a subsequent first transmission, so as to avoid that the second device misses the instruction.

[0174] FIG. 3B is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 3B, the embodiments of the present disclosure relate to a communication method applicable to the communication system 100, and the above method includes but is not limited to the following steps.

[0175] Step S3201, a first command is sent.

[0176] In some embodiments, the optional implementation of step S3201 can refer to the optional implementation of step S3101 of FIG. 3A and other associated parts of the embodiments involved in FIG. 3A, which are not repeated here.

[0177] In some embodiments, the "first command" in step S3201 is different from the "first command" in step 3101 of FIG. 3A in that the type of the "first command" in step S3201 is different, which can indicate that the first command includes a first identifier or indicates that the first command includes multiple identifiers or indicates that the first command includes a second identifier or indicates that the first command does not include any identifier. That is, the "first command" in step S3201 can not include first indication information, i.e. it is not necessary to indicate that the first command includes a first identifier or indicates that the first command includes multiple identifiers or indicates that the first command includes a second identifier or indicates that the first command does not include any identifier through the first indication information, but only the type of the first command can indicate whether the first command includes a first identifier or multiple first identifiers or a second identifier or does not include any identifier.

[0178] That is, four types of first commands can be defined, i.e. a first command for indicating a second device 102, a first command for indicating multiple second devices 102, a first command for indicating a group of second devices 102, and a first command for indicating all second devices 102, associated with different command types. In some embodiments, the type of the first command is a first type, which can be used to indicate that the first command includes a first identifier; the type of the first command is a second type, which can be used to indicate that the first command includes multiple first identifiers; the type of the first command is a third type, which can be used to indicate that the first command includes a second identifier; the type of the first command is a fourth type, which can be used to indicate that the first command does not include any identifier. Wherein, the first type, the second type, the third type and the fourth type are all different. For example, the type of the first command can be used to determine whether the first command includes a first identifier or multiple first identifiers or a second identifier or does not include any identifier.

[0179] Optionally, in some embodiments, as shown in FIG. 3B, the method can include step S3202.

[0180] Step S3202, determining the second device 102 to perform a first action according to the first command, the type of the first command and the second indication information.

[0181] In some embodiments, the first action can include any of the following: maintaining the current state; entering a target state and / or staying in the target state for a duration of the first duration. The target state can be the first state (the state of ON), or can be the second state (the state of OFF), or can be the third state (the state of SLEEP).

[0182] In some embodiments, the optional implementation of step S3202 can refer to the optional implementation of step S3102 of FIG. 3A and other associated parts of the embodiments involved in FIG. 3A, which will not be repeated here.

For example, when the value of the type of the first command is the eighth value, it indicates that the type of the first command is the first type, and the second device 102 can determine that the first command includes one first identifier. For example, when the value of the type of the first command is the ninth value, it indicates that the type of the first command is the second type, and the second device 102 can determine that the first command includes multiple first identifiers. For example, when the value of the type of the first command is the tenth value, it indicates that the type of the first command is the third type, and the second device 102 can determine that the first command includes a second identifier. For example, when the value of the type of the first command is the eleventh value, it indicates that the type of the first command is the fourth type, and the second device 102 can determine that the first command does not include any identifier or the first command includes a special value. For example, the eighth value can be 00, the ninth value can be 01, the tenth value can be 10, and the eleventh value can be 11. Alternatively, the eighth value, the ninth value, the tenth value, and the eleventh value can also be indicated in other ways, which will not be repeated here.

[0261] It is worth noting that the present disclosure proposes a power state method in IOT scenario, through which the CN / Reader (i.e. the above first device 101) can directly instruct IOT devices to enter a certain state, such as ON, OFF, SLEEP, etc. The advantage of the present solution is that the CN / Reader can determine to instruct the IOT device to enter the OFF / SLEEP state without the first transmission (i.e. the transmission from the CN / Reader to the IOT device), so as to make the IOT device save power as much as possible, reduce the number of charging and discharging, and improve the working performance of the IOT device. In addition, the CN / Reader can instruct the IOT device to enter the ON state in the case that there is a subsequent first transmission, so as to avoid that the IOT device misses the instruction. The following will be described in conjunction with examples.

[0262] In some embodiments, a first command is defined, the first command instructs one / group / all IOT devices to enter a first state and / or the duration of entering the first state.

[0263] Exemplarily, the first command contains an IOT device identity, indicating an IOT device to enter the first state.

Exemplarily, the first command contains a time length for entering the first state, and exemplarily, the time length can be, for example, the time length of the beginning / end of the first command. Exemplarily, the time length can be indicated by an absolute time, for example, the beginning / end of the first command passes an absolute time of us, ms, s, minute, hour, etc., or other ways, which are not limited in the present disclosure.

[0265] In some embodiments, a common first command is defined. The first command indicating an IOT device, indicating a group of IOT devices, indicating all IOT devices shares a command type.

[0266] Embodiment: The first command can carry an EPC code or a MASK mask or none, and the first command carrying an EPC code and the first command carrying a MASK mask and none share the same command type, for example, to indicate that it is a first command.

[0267] Embodiment: define an indicator bit to indicate whether the first command carries EPC code or MASK mask or none. For example, 2-bit indicator bit, 00 indicates that the first command carries EPC code / indicates one tag, 01 indicates that the first command carries MASK mask / indicates a group of tags, 10 or 11 indicates that the first command carries neither EPC code nor MASK mask / indicates all tags. Or other forms of indication, not limited. Tag is distinguished by the indicator bit whether the first command indicates one tag, a group of tags or all tags.

[0268] In some embodiments, three kinds of first commands are defined. The first command indicating a specific tag and the first command indicating a group of tags and the first command indicating all tags are associated with different command types.

[0269] Embodiment: one first command carries EPC code, one first command carries MASK mask. One first command carries neither EPC code nor MASK mask.

[0270] Embodiment: the command type of the first command carrying EPC code and the first command carrying MASK mask and the first command carrying neither EPC code nor MASK mask is different. For example, the first command carries EPC code or MASK mask or none is indicated by different command types.
