Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0112] In the A-IoT Internet of Things, the number of A-IoT terminals (such as A-IoT devices and A-IoT tags) that can be accessed in the network is large, and they have simple structures, low hardware and maintenance costs, low power consumption, and can usually not need to replace batteries for a long time.

[0113] The application scenarios of IoT technology are quite extensive. IoT can be applied to scenarios involving the inventory of large-scale items, such as A-IoT terminals reporting Electronic Product Codes (EPCs) to the network / intermediate nodes / other terminals. IoT can also be applied to sensing scenarios such as smart homes and environmental monitoring, where A-IoT terminals report data when certain trigger conditions are met. IoT can also be applied to location scenarios, such as finding items or locating them within a shopping mall. Furthermore, IoT can be used in command scenarios, such as responding to commands sent from the network or terminals.

[0114] In some embodiments, the IoT terminal has a peak power consumption of 1μW, energy storage capabilities, an initial sampling frequency offset (SFO) of up to 10X ppm, and neither downlink (DL) nor uplink (UL) amplification is present in the device. The device's UL transmission is backscattered on an externally provided carrier.

[0115] In some embodiments, the IoT terminal has a peak power consumption of ≤ several hundred μW, energy storage capabilities, and a surface area factor (SFO) of up to 10X ppm, enabling deep transmission (DL) and / or ultra-low transmission (UL) amplification within the device. The UL transmission of the device can be generated internally or backscattered on an externally provided carrier.

[0116] In some embodiments, ambient IoT terminals can be categorized into the following three types:

[0117] Device A: Cannot perform independent signal generation / amplification, such as using backscatter operation; does not have the ability to amplify DL and / or UL signals.

[0118] Device B: It has energy storage capabilities but cannot generate signals independently, such as using a backscattering operation mode; the stored energy can be used for DL ​​and / or UL signal amplification.

[0119] Device A / B can use a simple modulation and demodulation method, such as on-off keying (OOK) or phase shift keying (PSK).

[0120] Device C: has energy storage capability, can independently generate signals, such as active signal sending radio frequency (RF) module. A more complex modulation and demodulation method can be used, such as orthogonal frequency division multiplexing (OFDM) modulation and demodulation. The uplink or downlink signal can be amplified.

[0121] Among the above three terminal types, Device C has the strongest capability and the highest cost. Device A has the weakest capability and the lowest cost. In addition, Device A and Device B can only use backscatter mode and cannot actively send signals. When they need to send information, they must have an external continuous wave (CW) to provide backscatter. The coverage of the terminal supported by Device A and Device B is smaller, but the power consumption of the working mode of Device A and Device B is much smaller than that of Device C.

[0122] For devices using backscatter mode, a CW node needs to provide a CW for reflection while transmitting data. The CW is generally constant in amplitude, and the CW node can be a separate node or a network / intermediate node (such as other terminals) communicating with the device. The A-IoT terminal reflects the received CW and loads the signaling / data to be transmitted onto the reflected wave to send it out. The reflected wave and the CW are the same frequency or have a certain frequency offset. At the same time, the CW can also serve to charge the A-IoT terminal, for example, the A-IoT terminal receives a wireless signal CW, activates the internal receiving processing module to start working, and encodes and modulates the signaling / data to be uploaded by the A-IoT terminal.

[0123] In some embodiments, A-IoT network terminals include networks, terminals, intermediate nodes, auxiliary nodes, etc. The intermediate node can be a relay, an integrated access and backhaul (IAB) node, a terminal, or a repeater.

[0124] FIG. 1B is a schematic diagram illustrating a deployment structure according to an embodiment of the present disclosure. FIG. 1C is a schematic diagram illustrating another deployment structure according to an embodiment of the present disclosure.

[0125] In some embodiments, the A-IoT terminal can support two deployment structures: Topology 1 as shown in FIG. 1B and Topology 2 as shown in FIG. 1C.

[0126] In Topology 1, the A-IoT terminal and the network (e.g., a base station (BS)) directly perform DL and UL data reception and transmission.

[0127] In Topology 2, the A-IoT terminal and the network (BS) indirectly perform DL and UL data reception and transmission through an intermediate node; the intermediate node is used for data forwarding, and the intermediate node and the BS perform data transmission through a Uu interface.

[0128] In some embodiments, in a passive Internet of Things system, the data sent by the terminal can be of the following types:

[0129] Based on network demand reporting data, such as inventory inventory.

[0130] Based on environmental IOT triggers, such as the temperature of a sensor (Sensor) being higher than a configured threshold.

[0131] Periodic data reporting: periodic requests from the network to achieve periodic environmental Internet of Things data reporting; or based on environmental IOT triggers, to achieve periodic environmental Internet of Things data reporting (due to power discontinuity, it is difficult to implement timing).

[0132] In some embodiments, in 6G Internet of Things, there can be terminals with capabilities stronger than A-IOT terminals, such as terminals that can support inter-terminal communication, have cache information capabilities, and have the ability to actively send. 6G Internet of Things will be expected to support the interconnection of Internet of Things terminals, improve the quality and efficiency of information exchange, and bring more convenience to life and production. For example, in the smart home scenario, after a person leaves home and closes the password door, the password door can send instructions to the sweeping robot, and the sweeping robot starts working. End-to-end direct communication technology has the characteristics of low latency, high reliability, and anti-interference. Internet of Things terminals interconnect to ensure that information is effectively delivered to better meet the future various applications of smart homes and improve the efficiency and reliability of the entire smart home system.

[0133] In 6G Internet of Things (IoT), in addition to the communication demand between IoT terminals and base stations, there can also be communication between IoT terminals. When a terminal communicates with a base station, for a terminal located at the edge of a cell, there can be a problem of insufficient uplink coverage when the terminal sends information to the network device due to insufficient remaining power of the terminal. Because long-distance communication generally means higher transmission power, i.e., more power consumption. Or, the terminal has a high reliability requirement for this communication, but the terminal has low capability, such as the power class of the terminal is class 6, according to the protocol, the maximum transmission power is low, only 14dbm, so there is a problem of insufficient uplink coverage. A feature of 6G IoT is that the density of IoT devices is very high, there are multiple IoT terminals near an IoT terminal, and these IoT terminals are close to each other. At this time, under the condition that the IoT terminals can communicate with each other, the information can be sent to the base station by the assistance of the IoT terminals to solve the problem of insufficient uplink coverage.

[0134] Therefore, the embodiments of the present disclosure provide a communication method, the first terminal sends first information to the second terminal under the condition that the power condition is met, and the second terminal forwards the first information to the network device, which can improve the reliability of transmitting information between the first terminal and the network device, thereby improving the communication efficiency.

[0135] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiments of the present disclosure relate to a communication method, and the method includes:

[0136] In step S2101, the second terminal 102 sends second information to the first terminal 101.

[0137] In some embodiments, the first terminal 101 and the second terminal 102 each include an IoT terminal.

[0138] For example, the first terminal 101 can be a 6G IoT terminal, such as an A-IoT terminal; and the second terminal 102 can also be a 6G IoT terminal, such as an A-IoT terminal.

[0139] In some embodiments, the first terminal 101 and the second terminal 102 can belong to the same group, the group includes multiple terminals, the multiple terminals include the first terminal 101 and the second terminal 102, and each terminal in the group has a member identifier (ID).

[0140] In some embodiments, each terminal in the group can also periodically send the second information of each terminal to other terminals in the form of groupcast with a period p. That is, the second terminal 102 can send the second information of the second terminal to the first terminal 101. Wherein, the period p can be predefined, preconfigured, or dynamically indicated by physical layer control information on the Uu interface.

[0141] In some embodiments, the first terminal 101 can receive the second information of each terminal in the group except the first terminal 101. That is, the first terminal 101 receives the second information sent by the second terminal 102.

[0142] Wherein, the second information includes the remaining power of the second terminal and / or the power level of the second terminal.

[0143] For example, the second information includes the remaining power of the second terminal. For another example, the second information includes the power level of the second terminal. For yet another example, the second information includes the remaining power and the power level of the second terminal.

[0144] In the embodiments of the present disclosure, the second terminal sends the remaining power and / or the power level of the second terminal to the first terminal, so that the first terminal judges whether the second terminal meets the power condition of forwarding the first information.

[0145] Step S2102, the second terminal 102 sends the third information to the first terminal 101.

[0146] In some embodiments, each terminal in the group can send the third information of each terminal to other terminals in the form of groupcast. That is, the second terminal 102 can send the third information of the second terminal to the first terminal 101.

[0147] In some embodiments, the first terminal 101 can receive the third information of each terminal in the group except the first terminal 101. That is, the first terminal 101 receives the third information sent by the second terminal 102.

[0148] Wherein, the third information includes at least one of the following: the indication information of the second terminal, the member identifier of the second terminal, and the transmission power level of the second terminal.

[0149] In some embodiments, the indication information of a terminal can indicate whether the terminal is a terminal supporting information forwarding, and the terminals in the group that can support information forwarding can be indicated by a network device. For example, a terminal belongs to at least one of a terminal with strong capability, a terminal that does not need to be charged, and a terminal that is always powered on, and the terminal can be a terminal supporting information forwarding.

[0150] In some embodiments, the second terminal is a terminal supporting forwarding information, and thus the indication information of the second terminal indicates that the second terminal is a terminal supporting forwarding the first information.

[0151] In the embodiments of the present disclosure, the second terminal sends at least one of indication information indicating whether the second terminal is a terminal supporting forwarding information, a sending power level, and a member ID to the first terminal, so that the first terminal determines whether to take the second terminal as a terminal forwarding information.

[0152] In step S2103, the first terminal 101 sends the first information to the second terminal 102.

[0153] In some embodiments, the first terminal 101 is a terminal that needs to send the first information to the network device.

[0154] In some embodiments, the condition is met, the first terminal 101 sends the first information to the second terminal 102, and the second terminal 102 is used to forward the first information to the network device.

[0155] That is, the second terminal 102 is a terminal forwarding the first information, and the second terminal 102 can help the first terminal 101 forward the first information to the network device, and the first terminal 101 can send the first information to the network device through the second terminal 102.

[0156] In some embodiments, the condition can be a power condition, that is, when the power condition is met, the first terminal 101 sends the first information to the second terminal 102, and the second terminal 102 is used to forward the first information to the network device.

[0157] In some embodiments, the power condition includes at least one of the following: the remaining power of the first terminal is less than a first power threshold; the remaining power of the first terminal is greater than or equal to a second power threshold and less than the first power threshold; the remaining power of the second terminal is greater than or equal to a third power threshold; the power level of the first terminal is less than a first power level threshold; the power level of the second terminal is greater than or equal to a second power level threshold; the sending power level of the first terminal is greater than or equal to a first power level threshold; the sending power level of the second terminal is less than a second power level threshold; the sending power of the second terminal is greater than the sending power of the first terminal; and the priority of the first information is lower than a priority threshold.

[0158] For example, the power condition can include that the remaining power of the first terminal is less than the first power threshold. That is, the remaining power of the first terminal is insufficient, for example, the remaining power of the first terminal cannot support the first terminal to send the first information to the network device. In the case where the remaining power of the first terminal is less than the first power threshold, the first terminal can send the first information to the second terminal instead of directly sending the first information to the network device.

[0159] The first power threshold can be predefined, preconfigured, dynamically indicated by control information, or determined by the following manner.

[0160] In an example, the first power threshold is determined based on at least one of the following: the first transmission power; and the first time length.

[0161] The first power threshold is denoted by I1, the first transmission power is denoted by P1, and the first time length is denoted by t; the first power threshold I1 can be the product of the first transmission power P1 and the first time length t, i.e., I1 = P1 x t.

[0162] In an example, the first transmission power P1 can be calculated by the formula P1 = min[pcmax, P0 + 10log(M) + a x PL + D]. Wherein, pcmax represents the maximum power of the terminal, 10log(M) indicates the normalized transmission power when the current uplink transmission occupies M frequency domain resource units, M is a positive integer, D is a transmission power offset, P0 represents the target power indicated by the network device, a represents a preset parameter indicated by the network device, and PL represents the path loss value, which can be obtained by the difference between the transmission power of the transmission reference signal indicated by the network device and the reference signal receiving power (RSRP) value measured by the terminal.

[0163] For example, the power condition can include that the remaining power of the first terminal is greater than or equal to the second power threshold and less than the first power threshold. That is, the remaining power of the first terminal cannot support the first terminal to send the first information to the network device, but can support the first terminal to send the first information to the second device. In the case that the remaining power of the first terminal is less than the first power threshold, the first terminal can determine whether the remaining power of the first terminal is greater than or equal to the second power threshold, and in the case that the remaining power of the first terminal is greater than or equal to the second power threshold, the first terminal sends the first information to the second terminal.

[0164] The second power threshold can be predefined, preconfigured, dynamically indicated by control information, or determined by the following manner.

[0165] In an example, the second power threshold is determined based on at least one of the following: the second transmission power; and the second time length.

[0166] wherein the second power threshold is denoted as I2, the second transmission power is denoted as P2, and the second time length is denoted as t'. The second time length t' can be the same as or different from the first time length t. The second power threshold I2 can be the product of the second transmission power P2 and the second time length t2', i.e., I2 = P2 x t2'.

[0167] In an example, the second transmission power P2 can be calculated by the formula P2 = min[pcmax, P0' + 10 log (M) + a' x PL'], wherein P0' represents a target power indicated by the network device, a' represents a preset parameter indicated by the network device, and PL' represents a path loss value, which can be calculated by a reference signal between terminals.

[0168] For example, the power condition can include that the remaining power of the second terminal is greater than or equal to a third power threshold, and the third power threshold is the same as the first power threshold, or the third power threshold is greater than the first power threshold. That is, the remaining power of the second terminal can support the second terminal forwarding the first information to the network device.

[0169] In an example, the terminals other than the first terminal in the group send their remaining powers to the first terminal, and the first terminal determines, according to the remaining powers of each of the other terminals, a terminal whose remaining power is greater than or equal to a third power threshold as the second terminal. If there are multiple terminals whose remaining powers are greater than or equal to the third power threshold, the first terminal can randomly determine one of them as the second terminal, or the first terminal can determine the terminal with the largest remaining power as the second terminal.

[0170] For example, the power condition can include that the remaining power of the first terminal is greater than or equal to a second power threshold and less than the first power threshold, and the remaining power of the second terminal is greater than or equal to a third power threshold.

[0171] For example, the power condition can include that the power level of the first terminal is less than a first power level threshold.

[0172] The first power level threshold can be predefined, preconfigured, or dynamically indicated by control information.

[0173] For example, four power levels are defined: level 1, level 2, level 3, and level 4, and the higher the power level of a terminal, the higher the remaining power value of the terminal. The first power level threshold can be set to level 1, for example. When the power level of the first terminal is level 1, the power level of the first terminal is less than the first power level threshold, and in this case, the condition is determined to be met.

[0174] For example, the power condition can include that the power level of the second terminal is greater than or equal to a second power level threshold.

[0175] The second power level threshold value can be predefined, preconfigured, or dynamically indicated by control information. The second power level threshold value is the same as the first power level threshold value, or the second power level threshold value is greater than the first power level threshold value.

[0176] For example, four power levels are defined: level 1, level 2, level 3, and level 4. The higher the power level of the terminal, the higher the remaining power value of the terminal. The second power level threshold value can be set to level 1, for example. When the power level of the second terminal is level 3, the power level of the second terminal is greater than the second power level threshold value, and in this case, it is determined that the condition is met.

[0177] For example, the power condition can include both that the power level of the first terminal is less than the first power level threshold value and that the power level of the second terminal is greater than or equal to the second power level threshold value.

[0178] In the embodiments of the present disclosure, on the basis of the at least one power condition described above, at least one of the following conditions is also met: the transmission power level of the first terminal is greater than or equal to the first power level threshold value; the transmission power level of the second terminal is less than the second power level threshold value; the transmission power of the second terminal is greater than the transmission power of the first terminal; and the priority of the first information is lower than the priority threshold value. For example, on the basis of the remaining power of the first terminal being less than the first power threshold value and the remaining power of the second terminal being greater than the second power threshold value, the transmission power of the second terminal is greater than the transmission power of the first terminal. For another example, on the basis of the remaining power of the first terminal being less than the first power threshold value and the remaining power of the second terminal being greater than the second power threshold value, the priority of the first information is lower than the priority threshold value.

[0179] For example, the condition can include that the transmission power level of the first terminal is greater than the first power level threshold value.

[0180] The first power level threshold value can be predefined, preconfigured, or dynamically indicated by control information.

[0181] For example, three power levels are defined: class 1, class 2, and class 3. The maximum transmission power value corresponding to class 1 is 23 dbm, the maximum transmission power value corresponding to class 2 is 20 dbm, and the maximum transmission power value corresponding to class 3 is 14 dbm. The higher the power level of the terminal, the lower the maximum transmission power value of the terminal. The first power level threshold value can be set to class 2, for example. When the power level of the first terminal is class 3, the power level of the first terminal is greater than the first power level threshold value, and in this case, it is determined that the condition is met.

[0182] For example, the condition can comprise that the transmission power level of the second terminal is less than or equal to a second power level threshold.

[0183] The second power level threshold can be predefined, pre-configured, or dynamically indicated by control information. The second power level threshold is the same as the first power level threshold, or the second power level threshold is greater than the first power level threshold.

[0184] For example, three power levels are defined: class 1, class 2, and class 3. The maximum transmission power value corresponding to class 1 is 23dbm, the maximum transmission power value corresponding to class 2 is 20dbm, and the maximum transmission power value corresponding to class 3 is 14dbm. The higher the power level of the terminal, the lower the maximum transmission power value of the terminal. The first power level threshold can be set to class 2, for example. When the power level of the second terminal is class 1, the power level of the second terminal is less than the first power level threshold, and in this case, it is determined that the condition is met.

[0185] For example, the condition can comprise that the transmission power of the second terminal is greater than the transmission power of the first terminal.

[0186] For example, the transmission power of the first terminal is 14dbm, and the transmission power of the second terminal is 23dbm. The transmission power of the second terminal is greater than the transmission power of the first terminal, and in this case, it is determined that the condition is met.

[0187] For example, the condition can comprise that the priority of the first information is lower than a priority threshold.

[0188] The priority and the priority threshold can be predefined, pre-configured, or dynamically indicated by control information.

[0189] For example, eight priority levels are defined, and the priority value is 0-7. The smaller the priority value, the higher the priority. For example, the priority threshold is 3. The priority value corresponding to the priority of the transmitted first information of the first terminal is 2, which is less than the priority threshold, and in this case, it is determined that the condition is met.

[0190] In some embodiments, if the larger the priority value, the higher the priority, the condition can comprise that the priority of the first information is higher than the priority threshold.

[0191] In an example embodiment, the first information is transmitted based on a first resource, and the first resource is also used to transmit at least one of the following: indication information of a second resource, the second resource being a resource used by the first terminal to transmit the first information to the network device; a source identifier, the source identifier being used to identify the first terminal; a destination identifier, the destination identifier being used to identify the network device; a member identifier, the member identifier being used to identify the second terminal.

[0192] That is, the first terminal sends the following at least one to the second terminal through the first resource: the first information; the indication information of the second resource, the source identifier, the source identifier; the destination identifier; and the member identifier.

[0193] For example, the first resource can be a link resource r2 between the first terminal and the second terminal. When the first terminal has the first information to be sent to the network terminal, the first terminal can use the link resource r2 between terminals in a multicast manner to send the first information to other terminals in the group. The link resource r2 can be a resource configured by the network for communication between terminals, or a resource determined by the terminal in the resource pool or resource set configured by the network for communication between terminals.

[0194] For another example, the first resource can also be other resources carrying the fourth information. The first terminal indicates the fourth information to the second terminal through the connection between terminals (such as the connection established through the PC5 interface), and the fourth information is carried in a new physical layer control information for communication between terminals or in a high layer information (such as a media access control layer control element (MAC CE)). The fourth information can include at least one of the first information; the indication information of the second resource, the source identifier, the source identifier; the destination identifier; and the member identifier.

[0195] The second resource is a time-frequency domain resource r1 indicated by the network device to the first terminal for the first terminal to send information to the network device. The second resource r1 can be pre-configured to the first terminal by the network terminal, or dynamically indicated to the first terminal by the interface (such as the Uu interface) between the network device and the terminal through control information. The second resource r1 can be indicated in the form of a bitmap, or in the form of a starting position + length. The indication of the starting position can be indicated by an offset value relative to the reference point of the time-frequency domain, or directly indicate the starting position, such as indicating which radio frame and which time slot in the radio frame, or by indicating the index corresponding to the resource. The second terminal sends the first information to the network device based on the second resource.

[0196] The source identifier is used to indicate that the first terminal needs other terminals to help it forward information. The member ID is used to indicate which terminal in the group to which the first terminal belongs needs to help itself forward information to the network device. Except for the first terminal, other terminals receiving the member ID will match whether the member ID and the member ID of the terminal itself are the same, and if they are the same, determine that the terminal itself is the terminal that needs to help the first terminal to forward information.

[0197] In an example embodiment, the second terminal uses the second resource for a third time length, the second terminal processes the first information for a fourth time length, the second terminal forwards the first information for a fifth time length, and the sum of the fourth time length and the fifth time length is less than or equal to the third time length.

[0198] In an example embodiment, the third time length can be represented by t1, the third time length can be the time length for which the second terminal uses the second resource, and the third time length can be indicated by the first terminal to the second terminal. The fourth time length can be represented by Tproc, the fourth time length can be the time length required by the second terminal to process the first information, and the value of Tproc can be defined by a protocol. The fifth time length can be represented by t2, and the fifth time length can be the time length required by the second terminal to forward the first information. The third time length t1, the fourth time length Tproc, and the fifth time length t2 can satisfy the following relationship: t1≥t2+Tproc, or t2+Tproc≤t1. That is, the third time length is greater than or equal to the sum of the fourth time length and the fifth time length, or the sum of the fourth time length and the fifth time length is less than or equal to the third time length. Thus, the time for the second terminal to forward the first information is ensured to be within the time corresponding to the resource for sending the first information.

[0199] In step S2104, the second terminal 102 sends the first information to the network device 103.

[0200] In some embodiments, the network device 103 receives the first information sent by the second terminal 102.

[0201] In some embodiments, the second terminal 102 sends the first information to the network device 103 based on the second resource.

[0202] In some embodiments, the network device 103 receives the first information sent by the second terminal 102 based on the second resource.

[0203] The communication method provided by the embodiments of the present disclosure can improve the reliability of information transmission between the first terminal and the network device by enabling the first terminal to send the first information to the second terminal under certain conditions and enabling the second terminal to forward the first information to the network device, thereby improving the communication efficiency.

[0204] The communication method related to the embodiments of the present disclosure can include at least one of steps S2101-S2104. For example, step S2103 can be implemented as an independent embodiment, steps S2101+S2103 can be implemented as an independent embodiment, S2102+S2103 can be implemented as an independent embodiment, and steps S2103+S2104 can be implemented as an independent embodiment, but are not limited thereto.

[0205] In some embodiments, steps S2101 and S2102 can be exchanged in order or performed simultaneously.

[0206] In some embodiments, step S2101 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0266] In some embodiments, the above method can include the method of the above-mentioned embodiments of the communication system side, the terminal side, the network device side, and the like, which will not be repeated here.

[0267] The embodiments of the present disclosure propose a communication method, through inter-terminal communication, one Internet of Things terminal helps another Internet of Things terminal in the group to forward information to the network device, thereby improving the reliability of communication between the Internet of Things terminal and the network device.

[0268] In some embodiments, when the following conditions are met, the information sent by the first terminal to the network terminal is sent to another terminal through the inter-terminal direct connection, and the other terminal forwards the information of the first terminal to the network terminal.

[0269] In some embodiments, the following one or more conditions must be met to use this method.

[0270] Condition 1: When the remaining power value of the first terminal is lower than a certain power threshold or meets a certain power level threshold, (satisfying this condition means that the remaining power of the first terminal is not enough to meet the power requirement of the terminal to send L length (L length is determined by the time length corresponding to the used resource) to the network device). At this time, the first terminal sends the information to be sent to the network terminal to another terminal, and the other terminal forwards the information of the first terminal to the network terminal, and the remaining power of the other terminal is greater than a certain threshold or meets a certain power level.

[0271] The following explains how the first terminal determines that the remaining power of the other terminal is greater than a certain threshold or meets a certain power level.

[0272] In some embodiments, a group connection is established between terminals, and each terminal in the group tells another first terminal in the group its member ID in the group in the form of groupcast, and periodically tells another first terminal in the group its remaining power value or power level in the form of groupcast at a period p. The first terminal determines the terminal that meets the condition according to the last received remaining power value or power level of the other terminal. When there are multiple terminals that meet the condition, the first terminal randomly selects a terminal to send the information to be sent to the network terminal to another terminal, and lets the other terminal forward the information of the first terminal to the network terminal.

[0273] The residual power threshold or the power level threshold is predefined, preconfigured, or dynamically indicated by the control information, or the residual power threshold is determined by the following method.

[0274] The first terminal needs to send information to the network device, and the sending duration is t. The sending power value P1 is calculated according to the power control parameter indicated by the network, P1xt = I1, and I1 is the power required for sending the information. The power threshold can be set as I1, but the residual power value is less than the required power threshold I1, and the terminal cannot meet the condition of sending information to the network device using power P1, and can only send information to the network device using power P2, but sending information to the network device using power P2 will cause uplink coverage shortage. P2 is the sending power calculated according to the power control parameter indicated between terminals, P2xt = I2, I2 is the power required for sending the information to another terminal, and the residual power value of the first terminal is greater than or equal to I2. Therefore, the first terminal sends the information sent to the network terminal to another terminal, and the other terminal forwards the information of the first terminal to the network terminal.

[0275] The power control parameters indicated by the network device to the Internet of Things device through system messages or Radio Resource Control (RRC) messages include P0, parameter a, and PL loss value calculated by the terminal itself. The terminal obtains the PL value according to the difference between the sending power of the reference signal indicated by the network device and the RSRP value of the reference signal measured on the terminal side. For example, the terminal finally calculates the sending power P1 = min[pcmax, PO + 10log(M) + a x PL + △], △ is an offset of the sending power, and 10log(M) indicates the normalized sending power when M frequency domain resource units are occupied in this uplink sending.

[0276] The power control parameters between terminals include the target power P0' indicated by the network device, the parameter a', and the loss value PL' calculated by the terminal according to the reference signal between terminals. For example, the terminal finally calculates the sending power P2 = min[pcmax, PO' + 10log(M) + a' x PL'], and 10log(M) indicates the normalized sending power when M frequency domain resource units are occupied in this sending between two terminals.

[0277] In some embodiments, when the group connection is established, each terminal in the group indicates whether it is a powerful second terminal and / or its member ID to other terminals in the group in the form of multicast. The second terminal (powerful terminal, such as a special terminal that does not need to be charged and is always powered on) can be used as the only forwarding terminal of the group. When all other terminals in the group need to forward information to the network device, they forward the information to the network device through the second terminal.

[0278] For example, four power levels are defined, such as levels 1, 2, 3, and 4. The higher the level, the higher the remaining power value of the terminal. When the power level threshold is level 1 and the power level of the first terminal is level 1, which is less than or equal to the threshold, the first terminal performs the above operation.

[0279] In some embodiments, the period p is predefined, preconfigured, or dynamically indicated by physical layer control information on the Uu interface.

[0280] Condition 2: When the maximum transmission power corresponding to the transmission power level of the first terminal is low, and / or the priority of the information transmitted by the first terminal is high, satisfying a certain priority threshold, the first terminal determines that another terminal (the lower the power level value, the greater the maximum transmission power) corresponding to another transmission power level value has a greater maximum transmission power than the first terminal. At this time, the first terminal transmits the information to be transmitted to the network terminal to another terminal, and the other terminal forwards the information of the first terminal to the network terminal.

[0281] The following describes how the first terminal determines another terminal with a greater maximum transmission power.

[0282] There can be multiple types of device terminals in the network. When the group connection is established, each terminal in the group tells other terminals in the group its power level value and its member ID in the group in the form of multicast.

[0283] The power level threshold and the priority threshold are predefined, preconfigured, or dynamically indicated by control information.

[0284] For example, the power level value defines 3 power levels, class 1, class 2, and class 3. The maximum transmission power value corresponding to class 1 is 23dbm, the maximum transmission power value corresponding to class 2 is 20dbm, and the maximum transmission power value corresponding to class 3 is 14dbm. The power level threshold is class 1. The priority level of the information sent by the first terminal is defined, for example, 8 priority levels are defined, the priority level value is 0-7, the smaller the value, the higher the priority. When the priority threshold is 3, and the priority value of the information sent by the first terminal is 2, which is less than the priority threshold, the priority condition is met. The first terminal determines the terminal whose maximum transmission power corresponding to the power level is greater than itself, for example, the power level of the first terminal is class 3, and the corresponding maximum transmission power is 14dbm. Then the first terminal determines that the power level of another terminal is class 1. Then the first terminal executes the above process and selects another terminal with a power level of class 1 to forward the information to the network terminal.

[0285] When there are multiple terminals meeting the conditions, the first terminal randomly selects one terminal to send the information sent to the network terminal to another terminal, so that the other terminal forwards the information of the first terminal to the network terminal.

[0286] In some embodiments, a group is formed among multiple Internet of Things terminals. When the first terminal in the group has information to send to the network terminal, the first terminal sends the information to other terminals in the group through the link resource r2 between terminals by using the multicast mode. Another Internet of Things terminal that receives the information and meets the ID condition caches the information. Another terminal sends the information to the network terminal on the time-frequency domain resource r1 indicated by the first terminal in the future.

[0287] In some embodiments, the group of Internet of Things terminals can be established based on the following methods: distance threshold and zone ID. For example, the first terminal obtains its own position according to the Global Navigation Satellite System (GNSS), and calculates the distance between the first terminal and the center position of the zone closest to the first terminal among multiple zones corresponding to the zone ID of other terminals according to the zone ID of other terminals. If the distance is less than or equal to the distance threshold, the first terminal will determine that the other terminal and the first terminal belong to the same group. The zone ID is indicated to the Internet of Things terminal by high-level information. When establishing the connection between terminals, the Internet of Things terminal tells the other terminal its own zone ID, or the Internet of Things terminal tells the other terminal its own zone ID in the control information between terminals when sending information. For example, the length of the zone ID is 12 bits.

[0288] In some embodiments, the earth surface is divided into multiple zones, and each zone is identified by a zone ID. The specific calculation formula of the zone ID is as follows:

[0289] x1 = Floor(x / L) Mod 64;

[0290] y1 = Floor(y / L) Mod 64;

[0291] Zone_id = y1*64 + x1.

[0292] Wherein, L is the value of the length of the zone contained in the zone configuration, x is the geodesic longitude distance between the current position of the UE and the geographic coordinate (0, 0) according to the WGS84 (World Geodetic System 1984, a coordinate system) model, expressed in meters; y is the geodesic latitude distance between the current position of the UE and the geographic coordinate (0, 0) according to the WGS84 model, expressed in meters; Floor represents the floor operation, and Mod represents the modulo operation.

[0293] In some embodiments, the first Internet of Things terminal has information to send, and indicates the following information to another Internet of Things terminal through a connection between terminals (such as a connection established similar to a PC5 interface). These information is carried in a new physical layer control information for communication between terminals, or carried in high layer information (such as MAC CE).

[0294] Information 1: Information (i.e. transport block (TB)) that needs to be forwarded by the first terminal with the help of another terminal.

[0295] Information 2: Time-frequency domain resource r1 for sending the information (TB) to the network terminal. The resource r1 can be a resource pre-configured to the terminal by the network terminal, or a resource dynamically indicated to the terminal by the control information between the network terminal and the terminal (Uu interface). The indication of the resource is indicated in the form of bitmap, or indicated in the form of start position + length. The indication of the start position can be indicated by the offset value relative to the reference point of the time-frequency domain, or directly indicate the start position, such as indicating which radio frame and which time slot in the radio frame, or the indication of the time domain resource is by indicating the index corresponding to the resource. (The resource needs to be used by the other terminal to forward the information to the network device).

[0296] The frequency domain resource is indicated by a bitmap, and is indicated by a bitmap with a length of L. The length L of the bitmap is equal to the number of all frequency domain resources configured for the IOT terminal, and each 1 bit indicates whether the resource unit can be used, and a bit value of 1 indicates that the frequency domain resource is available, and a bit value of 0 indicates that the frequency domain resource is not available.

[0297] Information 3: ID information, including source ID information and / or destination ID and / or member ID information. The ID information is used to indicate that the first terminal needs other terminals to help it forward information, and the member ID is used to indicate which terminal in the group to which the first terminal belongs needs to help it forward information to the network device. After the other terminal receives the member ID information, it is matched with the member ID of the terminal itself to determine whether the terminal itself is the terminal that needs to help the first terminal forward information.

[0298] In some embodiments, the time corresponding to the resource r1 used by the other terminal is t1, and the time at which the first terminal sends the information to be forwarded to the other terminal is t2. The relationship between t1 and t2 needs to satisfy the following relationship: t1≥t2+Tproc, Tproc is the processing time of the terminal, that is, the time of the other terminal for demodulating or decoding and buffering the information sent by the first terminal, which ensures that the other terminal forwards the information cannot exceed the time corresponding to the resource of the sent information, and the value of Tproc is defined by the protocol.

[0299] In some embodiments, the resource r2 is a resource used by the first terminal to send the information to be forwarded to the other IOT terminal. The resource r2 can be a resource pre-configured by the network for communication between IOT terminals, or a resource determined by the terminal itself according to some resource exclusion method in a resource pool or resource set configured by the network for communication between terminals.

[0300] In the embodiments of the present disclosure, part or all of the steps and optional implementation manners thereof can be combined with part or all of the steps in other embodiments, or can be combined with optional implementation manners of other embodiments.
