[0130] FIG2A is a flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to a communication method for an AIOT device 1101, the method comprising:

[0131] Step S2101: Determine a first number N1 of information to be sent and a first transmission power P1 of each information to be sent.

[0132] In some embodiments, the first number may also be referred to as "N sche,TX "wait.

[0133] In some embodiments, the first transmission power may also be referred to as "P one "wait.

[0134] In some embodiments, the first transmission power P1 may be the power for transmitting a data signal, or may be the power for transmitting a signaling signal, etc., which is not limited in the present disclosure.

[0135] In some embodiments, the first transmission power P1 of each information transmission may be determined by the AIOT device based on a formula for calculating the transmission power specified in the protocol, which is not limited in the present disclosure.

[0136] In some embodiments, terms such as "AIOT", "Ambient Internet of Things", and "Ambient Internet of Things" can be used interchangeably.

[0137] In some embodiments, the formula specified in the protocol for calculating the power of information sent by the AIOT device may be determined by one or more of the following: path loss, target received power, frequency domain resources occupied by the transmitted information, and amplification parameters of the signal by the AIOT device, etc. This disclosure does not limit this.

[0138] In some embodiments, in order to improve resource efficiency, the AIOT device can use the same time-frequency domain resources, different code domain resources, or spatial domain resources to send information to multiple network devices 11012 or terminals 11011.

[0141] In some embodiments, AIOT devices can be divided into two types. The first type of AIOT device can store energy and operate based on backscatter. For AIOT devices using backscattering, when sending data, they need an energy source (CW node) that provides continuous electromagnetic waves (CW) to provide them with electromagnetic waves for backscattering. When the AIOT device reflects the received CW, it can load the signaling / data to be transmitted onto the reflected wave and send it out. The reflected wave and the CW can be at the same frequency, or there can be a certain frequency offset. At the same time, the CW can also charge the AIOT device. After receiving the wireless signal CW, the first type of AIOT device can encode and modulate the signaling / data that the AIOT device needs to upload by activating the internal receiving processing module. As a result, the first type of AIOT device has low complexity and low power consumption, but it cannot amplify uplink or downlink signals.

Instead, it can operate using its own stored energy or battery power, that is, it can operate based on active transmission. However, this type of AIOT device can also operate based on backscattering. Specifically, this type of AIOT device can amplify uplink or downlink signals.

[0143] In some embodiments, the continuous electromagnetic wave CW generally has a constant amplitude, which is not limited in the present disclosure.

[0154] In some embodiments, the number of target information sent may also be referred to as "N TX "wait.

[0155] In some embodiments, the second transmission power may also be referred to as "P k "wait.

[0156] In some embodiments, the second transmission power is the transmission power at which the device ultimately transmits the target information.

[0157] In some embodiments, the sum of N1 and P1 is less than or equal to P max In this case, the first number of information to be sent may not be controlled, and the first transmission power of each information to be sent may not be controlled. At this time, the transmission power P2 of each target information is equal to P1.

[0346] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0347] In the embodiments of the present disclosure, each step can also be implemented independently.

[0348] In this embodiment, by determining the maximum amount of information to be sent and / or the maximum transmission power, the target transmission information and the corresponding transmission power are determined from the information to be sent, thereby improving the reliability of the communication method and the efficiency of the communication system.

[0349] The following is an exemplary introduction to the above method.

[0350] The present disclosure is used to implement a method for power control when an AIOT device establishes a connection with multiple network nodes or multiple AIOT devices and sends and receives information. The optional implementation solutions are as follows:

[0351] The present disclosure relates to a communication method, which includes:

[0352] Assume that an AIOT device uses the same time-frequency domain resources, but different code domain resources or spatial domain resources, to send signaling or data to multiple network devices. The AIOT device has N1 messages to send, and after power control, the AIOT device determines that the number of messages to send is N2. The AIOT device calculates the transmit power of each message as P1 according to the protocol's transmit power formula, and after power control, the AIOT device determines the transmit power of each message as P2. The N1 messages from the AIOT device are sent to different network devices, meaning that the AIOT device can communicate with multiple network devices.

[0353] Assuming that the AIOT has sufficient energy storage and the AIOT device has amplification capabilities and can amplify, the AIOT device will amplify the transmitted signal. P1 is the transmit power value calculated according to the formula specified in the protocol, which is the transmit power determined after taking into account the amplification of the AIOT device.

[0354] The formula for calculating the power transmitted by the AIOT device, as specified in the protocol, is determined by path loss, and / or target received power, and / or occupied frequency domain resources, and / or the signal amplification parameters of the AIOT device.

[0355] If the maximum number of messages that can be sent simultaneously supported by the AIOT device capability is N max The specific power control process can be divided into the following cases:

[0356] Case 1: If the number of messages to be sent, N1, is less than or equal to N max , the power of sending each message is P1, and the total power of N1 messages is less than or equal to P max When the AIOT device determines that the number of messages to be sent is N1, and the transmission power of each message is P2 = P max (No more than P max and N max , then all the information to be sent can be sent, and the sending power of each information does not need to be adjusted).

[0357] Case 2: If the number of messages to be sent, N1, is less than or equal to N max , and the transmission power of each message is P1, the total power of N1 messages is greater than P max When

[0358] Method 1: When the AIOT device determines that the number of messages to be sent is N2=N1, the AIOT device does not drop the messages, but needs to reduce the transmission power of each message so that the transmission power of each message is P2=min[P1, P3], where P3=P max -10log(N2) (because the total power is greater than P max , so the transmission power of each message needs to be adjusted, where P max -10log(N2) refers to the P max Evenly distributed to N2 information).

[0359] Method 2: If the AIOT device loses some information, you can use the following method 1 or 2 to determine the final N2 (N2 is less than N1) messages to be sent, but the transmission power of each message remains unchanged. That is, after power control, the transmission power of each message P2 = P1.

[0360] Case 3: If the number of messages to be sent N1 is greater than N max , and the transmission power of each message is P1, and the total transmission power of N1 messages is less than or equal to P max When N2=N, the AIOT device determines the final number of messages to be sent. max When the AIOT device loses some information, it can determine the final N2 information to be sent according to the following scheme 1 or scheme 2, and the transmission power of each information is P2 = P1 (because as long as it does not exceed P max , the transmission power of each message will not be adjusted).

[0361] Case 4: If the number of messages to be sent, N1, is greater than N max , and the transmission power of each message is P1, the total transmission power of N1 messages is greater than P maxWhen N2=N, the AIOT device determines the final number of messages to be sent. max When the AIOT device needs to drop some information, it can determine the final N2 information to be sent according to the following schemes 1 and 2, and the transmission power of each information needs to be adjusted, that is, P2 = min[P1, P3], where P3 = P max -10log(N2) (because the total power is greater than P max , so the transmission power of each message needs to be adjusted, where P max -10log(N2) refers to the P max The information is divided into N2 pieces on average. P1 is likely to be smaller than P max -10log(N2), N1 P1 is greater than P max Yes, but N max P1 is likely to be smaller than P max Yes, P max The value of -10log(N2) may be greater than P1, so it must be equal to the minimum of the two).

[0362] If there is no specification on the maximum number of messages that AIOT devices can support sending simultaneously, N max The specific power control process is divided into the following cases (there is no need to consider N at this time max ):

[0363] Case 1: If the transmission power of each message is P1, and the total power of N1 messages is less than or equal to P max When , the AIOT device can determine the number of messages to be sent N2 = N1, and the transmission power of each message is equal to P2 = P1.

[0364] Case 2: If the transmission power of each message is P1, and the total power of N1 messages is greater than P max When P is , the AIOT device can determine that the number of messages to be sent is N2 = N1, but it needs to reduce the transmission power of each message. max Divide it evenly into N2 pieces of information, that is, P2=P max -10log(N2).

[0365] Solution 1: The terminal device discards information according to parameters related to the Quality of Service (QOS) of the transmitted information.

[0366] Example 1: Drop the transmission of the corresponding information in descending order according to the priority of the information until the sum of the transmission power of N2 information does not exceed the maximum transmission power P max .

[0367] Priority refers to the priority of the transmitted information (signaling or data). The smaller the priority value, the greater the priority.

[0368] When multiple messages have the same priority, it may be up to the UE implementation to discard certain messages.

[0369] Example 2: Drop the corresponding information transmission in descending order according to the information delay requirement until the sum of the transmission power of N2 information does not exceed the maximum transmission power P max .

[0370] For example, the transmission of corresponding information is dropped in descending order according to the Packet Delay Budget (PDB) values.

[0371] The maximum uplink transmission power P of the AIOT device max It can be pre-configured, configured, pre-defined, or indicated by physical layer or higher layer information signaling.

[0372] Optional, P max It is related to the type of AIOT device. The stronger the device capability, the higher the P max The larger the value.

[0373] Such as P devices with energy storage and active data transmission max Compared to devices based on backscattering.

[0374] Solution 2: When AIOT devices discard information based on information type, they first discard the transmission of the first type of information. If the sum of the transmission powers still cannot be less than or equal to the maximum transmission power, they discard the transmission of the Nth type of information until the sum of the transmission powers of N2 information does not exceed the maximum transmission power (N is an integer).

[0375] Optionally, when discarding a certain type of information, if the information type contains multiple information, the information may be discarded in order of priority from low to high; when the priorities of multiple information are equal, it may depend on the implementation of the UE to discard certain information.

[0376] Example 1: The first type is control (signaling) information, and the second type is data information. Then the AIOT device can discard the control (signaling) information first, and then discard the data information when the sum of the powers still cannot be less than or equal to the maximum transmit power.

[0377] Example 2: An AIOT device can transmit sensory information (such as temperature, remaining gas volume, remaining power, environmental data, etc.), some positioning information (such as Reference Signal Time Difference (RSTD); Reference Signal Time Of Arrival (RTOA)), and some inventory-related information (such as the product's electronic product code, product ID information, etc.). The AIOT device can discard sensory information first, and discard positioning information when the sum of the power still cannot be less than or equal to the maximum transmit power.

[0378] Example 3: If the first type is broadcast / multicast information and the second type is unicast information, the AIOT device may discard the broadcast / multicast information first. If the sum of the powers still cannot be less than or equal to the maximum transmit power, the unicast information may be discarded.

[0379] The power of sending each information refers to, for example, the power of sending a data signal, the power of sending a signaling signal, etc. The information may refer to a signal.

For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods.
