[0028] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0029] For example, communication between IoT devices and base stations uses frequency division duplexing (FDD) for uplink and downlink communication, meaning that uplink and downlink signals use different frequency bands and / or frequencies. IoT devices can be categorized as active (e.g., with batteries and energy storage) or passive (without batteries), and their signaling and transmission considerations may differ. Communication between base stations and IoT devices is often used in scenarios such as inventory. During an inventory, the base station sends an inventory command, and the IoT device responds by returning a string of random numbers. If the base station receives a random number correctly, it sends an ACK (including the received random number). Upon receiving an ACK command that matches its own random number, the IoT device determines that its inventory was successful and returns a PC (Protocol Control) and EPC (Electronic Product Code). Inventory continues until all IoT devices have been successfully inventoried. IoT devices with low complexity and low power consumption have limited communication range.

[0030] In order to solve the above-mentioned problem of limited communication distance, the present application provides a communication method that can effectively increase the communication distance between nodes.

[0031] The first communication node can be a user equipment (UE), a terminal device, a repeater, etc.; the second communication node can be a base station; the third communication node can be an Internet of Things device, Bluetooth, etc., wherein the Internet of Things device can be an Ambient-Iot device, or a low-power-IoT device, etc.

[0032] FIG1 is a flow chart of a communication method provided by an embodiment. As shown in FIG1 , the communication method according to the embodiment of the present application is applied to a first communication node. The method includes S110 to S140:

[0033] S110. Receive first signaling sent by the second communication node, where the first signaling includes information for communication with the third communication node.

[0034] The first signaling may be used to instruct the first communication node to communicate with the third communication node as an intermediate node, thereby assisting communication between the second communication node and the third communication node. The first signaling may carry information, including relevant information regarding communication with the third communication node, and may be used to instruct the second communication node on what type of information to send to the third communication node, how to send information to the third communication node, and so on.

[0035] The first communication node communicates with the second communication node. When the second communication node needs to communicate with the third communication node, it generates a first signaling based on the content and information type required for communication and sends it to the first communication node. The first communication node receives the first signaling based on the communication method agreed upon with the second communication node.

[0036] In the present application, a first communication node can form a first system with a second communication node for communication, the air interface between the first communication node and the second communication node is a first air interface, the transmission mode between the first communication node and the second communication node is a first transmission mode, and the transmission link between the first communication node and the second communication node is a first transmission link. The first communication node can form a second system with a third communication node for communication, the air interface between the first communication node and the third communication node is a second air interface, the transmission mode between the first communication node and the third communication node is a second transmission mode, and the transmission link between the first communication node and the third communication node is a second transmission link.

[0037] In some embodiments, the first signaling carries at least one of the following: inventory information, read information, write information, selection information, trigger command, paging command, scheduling command, access command, wake-up information, indication to activate the first communication node as an intermediate node, etc.

[0038] The information for communicating with the third communication node included in the first signaling may further include a command or information for triggering the first communication node to communicate with the third communication node.

[0040] The first signaling may be a non-access stratum (NAS) message, or a radio resource control (RRC) message, or downlink control information (DCI), or a medium access control control element (MAC CE), or layer one signaling, or small data signaling; for example, the information carried in the first signaling is different, and the first signaling format is different. For example, if the first signaling carries an inventory command or an access command, the first signaling is an RRC signaling (for example, an RRC release signaling or a signaling specifically indicating that the first communication node communicates with the third communication node, or a new RRC signaling); for example, when the first signaling carries a read command or a write command, the first signaling is a DCI, or a MAC CE, or a layer one signaling.

[0041] S120. Send a second signaling to the third communication node, where the second signaling is related to the first signaling.

[0042] The second signaling is used to instruct the third communication to perform related operations, such as inventory operations, reporting of collected data and information, etc.

[0043] The first communication node generates a second signaling according to the instruction of the received first signaling, for example, determines the operation to be performed according to the first signaling, and generates the second signaling according to the operation to be performed. The first communication node sends the second signaling to the third communication node according to the communication mode negotiated with the third communication node.

[0044] In some embodiments, the first signaling instructs the first communication node to perform an inventory operation and includes information required for the inventory. The first communication node sends a second signaling to the third communication node based on the first signaling, wherein the second signaling carries the inventory command.

[0045] In some embodiments, the second signaling includes multiple signalings, and the multiple signalings are sent at different times. The multiple signalings can be used to instruct a third communication node to perform different operations, or to instruct different third communication nodes to perform the same or different operations, and so on.

[0046] The communication method provided in the embodiment of the present application solves the problem of limited communication distance between the second communication node and the third communication node. The first communication node acts as an intermediate node between the second communication node and the third communication node, assisting the second communication node and the third communication node in communicating, effectively expanding the communication distance between the second communication node and the third communication node, so that the device can be better used in different scenarios, and the third communication node with low complexity and low power consumption can be widely used.

The third signaling may include the execution result of the corresponding operation performed according to the second signaling, the relevant information fed back according to the second signaling, etc. After receiving the second signaling, the third communication node may perform the relevant operation. After the execution is completed, the third signaling is generated based on the execution result and fed back to the first communication node. The first communication node receives the third signaling based on the communication method between it and the third communication node.

[0052] S240. Send a fourth signaling to the second communication node, where the fourth signaling is related to the third signaling.

[0053] The fourth signaling is used to feed back corresponding information to the second communication node, and the fourth signaling is determined based on the third signaling. After receiving the third signaling, the first communication node analyzes the third signaling, for example, to determine whether the third communication node is operating normally, the status of the third communication node, operating parameters, specific data collected, etc., and generates the fourth signaling based on the analysis results, or directly uses the information carried in the third signaling as information in the fourth signaling to generate the fourth signaling, etc.

[0054] After completing the work / operation / content indicated in the first signaling, the first communication node may send feedback information / signaling to the second communication node, wherein the feedback information may be carried by the fourth signaling, or a new signaling may be sent additionally.

For example, the UE capability indicates a minimum value, and the time cannot be less than the minimum value.

[0078] When the first communication node assists the second communication node and the third communication node as an intermediate node, the services of the first communication node in the first system and the services of the first communication node in the second system transmitted as the intermediate node need to be considered jointly.

The second condition can be set based on information such as received and sent signaling, channel quality, and the duration of the first time period. The second condition is pre-set and a test is performed to determine whether the second condition is met.

[0340] Taking the first communication node as a user UE, the second communication node as a base station, and the third communication node as an IoT device as an example, the communication process is described through the following embodiments:

[0341] Example 1

[0342] When the UE acts as an intermediate node to assist the IoT device in communicating with the base station, the UE interrupts (or stops) communication with the base station as a terminal for a period of time (a first time period). During this period, the terminal communicates with the IoT device. The details are as follows:

[0343] For the setting of the first time period, please refer to Example 6.

[0344] In some embodiments, after the UE receives the first signaling sent by the base station, the UE interrupts communication with the base station as a terminal.

[0345] In some embodiments, after the UE receives the first signaling sent by the base station, after the first effective time has passed, the UE interrupts communication with the base station as a terminal.

[0346] In some embodiments, the UE receives the first signaling sent by the base station, and after the UE sends feedback information to the base station, the UE interrupts communication with the base station as a terminal.

[0347] In some embodiments, after the UE receives the first signaling sent by the base station and sends feedback information to the base station, the UE interrupts communication with the base station as a terminal after the second effective time has passed.

[0348] In some embodiments, after the UE receives the first signaling sent by the base station, the UE starts communicating with the IoT device.

[0349] In some embodiments, after the UE receives the first signaling sent by the base station, after the first effective time has passed, the UE starts communicating with the IoT device.

[0350] In some embodiments, the UE receives the first signaling sent by the base station, and after the UE sends feedback information to the base station, the UE starts communicating with the IoT device.

[0351] In some embodiments, the UE receives the first signaling sent by the base station, and after the UE sends feedback information to the base station, the UE starts communicating with the IoT device after the second effective time has passed.

[0352] The feedback information mentioned above includes at least one of the following: ACK, and a time interval between sending the second signaling and sending the feedback information.

[0353] In some embodiments, after sending the first signaling, the base station also sends an RRC release signaling; the RRC release signaling instructs the UE to return to an idle / inactive state.

[0354] In some embodiments, the UE is in an extended discontinuous reception (eDRX) state / using an eDRX configuration when in an idle / inactive state. This means that the UE is in an idle / inactive state and applies the eDRX configuration, i.e., monitors, measures, or reports according to the eDRX configuration.

[0355] Being in the eDRX state / using the eDRX configuration means that the UE must meet the eDRX requirements when sending and receiving signaling (eg, first air interface signaling).

[0356] After the UE receives the RRC release signaling, the UE interrupts (or stops) communication between the terminal and the base station (or communication between the terminal and the first system / air interface / link).

[0357] After the UE receives the RRC release signaling, after the fourth effective time has passed, the UE interrupts the communication between the terminal and the base station.

[0358] After the UE receives the RRC release signaling, the UE starts communicating with the IoT device (or communication between the terminal and the second system / air interface / link).

[0359] After the UE receives the RRC release signaling, after the fourth effective time, the UE starts communication with the Internet of Things device (or is called communication between the terminal and the second system / air interface / link).

[0360] In some embodiments, the first signaling is carried in RRC release signaling.

[0361] In some embodiments, the first signaling implicitly indicates RRC release signaling, that is, the first signaling implicitly indicates RRC release.

[0362] In some embodiments, the first signaling carrying the first type of information implicitly indicates RRC release signaling, i.e., the first signaling carrying the first type of information implicitly indicates RRC release signaling. The first signaling carrying the second type of information does not implicitly indicate RRC release signaling, i.e., the first signaling carrying the second type of information does not implicitly indicate RRC release signaling.

[0363] The first type of information includes at least one of the following: inventory command, access command, paging command;

[0364] The second type of information includes at least one of the following: a read command, a write command, and ACK information.

[0365] The first type of information is for multiple IoT devices and does not specify a specific IoT device.

[0366] The second type of information is information for one or more specific IoT devices.

[0367] For example, if the first signaling includes an inventory / access command, the first signaling implicitly indicates RRC release. For example, if the first signaling includes a read / write command, the first signaling does not implicitly indicate RRC release.

[0368] In some embodiments, after the UE sends the second signaling, after a third effective time has passed, the UE interrupts communication with the base station as a terminal.

[0369] In some embodiments, after the UE sends the second signaling, the UE interrupts communication with the base station as a terminal.

[0370] The UE interrupting communication with the base station as a terminal or the UE starting communication with the third communication node indicates at least one of the following:

[0371] Do not send uplink signaling to the base station, do not receive (stop monitoring / receiving) downlink signaling sent by the base station, and do not perform measurements;

[0372] No uplink signaling is sent to the base station, and no downlink signaling is received from the base station. SSB measurements (for example, for Radio Resource Management (RRM) measurements) can be performed.

[0373] No PDCCH monitoring is performed, no uplink signaling is sent to the base station, and SSB measurements (for example, for RRM measurements) can be performed.

[0374] PDCCHs other than paging are not monitored, uplink signaling is not sent to the base station, and SSB measurements (for example, for RRM measurements, etc.) can be performed.

[0375] The uplink signaling is sent by the UE to the base station. For example, the uplink signaling can be a channel sounding reference signal SRS, a physical uplink shared channel PUSCH, a physical uplink control channel PUCCH, an ACK, a negative ACK, a scheduling request (SR), a buffer status report (BSR), a channel state information (CSI) report, etc.

[0376] The downlink signaling is sent by the base station to the UE. For example, the downlink signaling can be downlink control information DCI, physical downlink control channel (Physical Downlink Control Channel, PDCCH), physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), channel state information reference signal CSI-RS, synchronization signal block SSB, system information block (System Information Block, SIB), etc.

[0377] The UE interruption ends when the communication between the terminal and the base station or the communication between the UE and the Internet of Things device is met.

[0378] The second condition includes at least one of the following: the UE sends a fourth signaling, the UE receives a third signaling, a timer expires, a predefined time ends, a measurement result does not meet a condition, and the UE receives an indication of a fifth signaling.

[0381] In some embodiments, the SIB carries information that triggers the UE to perform random access.

[0382] In some embodiments, the SIB carries system message update information.

[0383] In some embodiments, the SIB carries an indication that the UE activates / falls back to communication with the second communication node.

[0384] In some embodiments, the fifth signaling is a paging message.

[0385] In some embodiments, the fifth signaling is paging DCI / paging PDSCH, that is, the fifth signaling is paging DCI / paging PDSCH.

[0386] UE interruption indicates that the communication between the terminal and the base station ends, which means that the UE can send / receive signaling that it could not send / receive during the interruption.

[0387] The UE interruption indicates the end of the communication between the terminal and the base station, which means that the UE stops / deactivates / forbids the communication with the third communication node.

[0388] The UE interruption ends the communication between the terminal and the base station, indicating that the UE activates / falls back to communication with the second communication node.

[0389] The UE interruption indicates the end of the communication between the terminal and the base station, which triggers the UE to perform random access.

[0486] In some embodiments, the UE may perform partial SSB measurements; for example, RRM measurements.

[0487] For example, the UE interrupting part of the communication with the base station means that the UE can send uplink signaling to the base station, cannot receive downlink signaling, and does not need to blindly detect the PDCCH.

[0498] The UE sends sixth signaling to the base station.

[0499] In some embodiments, the sixth signaling indicates that the UE wants to resume communication with the base station.

[0500] Example 3

[0501] During the period when the UE acts as an intermediate node to assist the IoT device in communicating with the base station, the UE can transmit part or all signaling with the base station in a period of time (second time period). When the UE transmits signaling with the base station, the UE interrupts communication with the IoT device.

[0524] Example 4

[0525] Define windows and use them to control the communication between UE, base station, and IoT devices.

[0526] In some embodiments, while the UE acts as an intermediate node to assist the IoT device in communicating with the base station, the UE may communicate with the base station within a specific window; outside the window, the UE stops communicating with the base station.

[0527] In some embodiments, stopping communication with the base station indicates that communication with the IoT device is possible.

[0528] In some embodiments, while the UE acts as an intermediate node to assist the IoT device in communicating with the base station, the UE may communicate with the IoT device within a specific window; outside the window, the UE stops communicating with the IoT device.

[0529] In some embodiments, stopping communication with the IoT device means that communication with the base station can be performed.

[0530] In some embodiments, the configuration information of the window is a signaling indication, or is pre-configured / pre-defined.

[0531] For example, the signaling indication or the configuration information of the preconfigured / predefined window includes at least one of the following: a window period, a window duration, an offset value, and a maximum value of the window period.

[0532] The offset value indicates the offset between the starting position of the window and the reference point.

[0533] The reference point can be the first signaling, feedback information, the second signaling, or the time domain position (e.g., frame / time slot / symbol / subframe, etc.) of the signaling sent by the UE to the IoT device.

[0534] The maximum number of window periods is the maximum number of windows that can appear when the UE acts as an intermediate node to assist the IoT device in communicating with the base station.

[0535] In some embodiments, after the number of windows reaches the maximum number of windows, subsequent windows are no longer valid (ie, the UE cannot communicate with the base station within the window).

[0536] In some embodiments, the windows appear periodically according to a window period.

[0537] Figure 4 provides a schematic diagram of a window. As shown in Figure 4, the reference point is the first signaling, the first window is after the offset of the first signaling, the window length is the duration, and the interval between windows is the period value. The UE can communicate with the base station within the window, but cannot communicate with the base station outside the window.

[0538] In some embodiments, the window is located after each reference point, or after an offset value after each reference point.

[0539] FIG5 provides a schematic diagram of another window. As shown in FIG5 , the reference point is the first signaling, the window is after the offset of the first signaling, the window length is the duration, and only one window is activated / appears after the reference point.

[0540] In some embodiments, if the UE is configured with DRX (i-DRX, c-DRX, or e-DRX), the configuration of the window reuses the DRX configuration.

[0541] That is, the DRX active time is the window period.

[0542] In some embodiments, the window ends when a third condition is met.

[0543] The third condition includes at least one of the following:

[0544] Receiving a signaling indicating window stop;

[0545] No signaling was received and / or no signaling was sent for a period of time.

[0546] The period of time is predefined or indicated by signaling.

[0547] In some embodiments, the window ends if the second condition is met.

[0548] In some embodiments, within a window, the UE may receive and / or transmit data at specific resource locations.

[0549] In some embodiments, the specific resource location is represented by another small window.

[0550] The settings / definition of the other small window are the same as the window definition.

[0551] In some embodiments, specific resource locations are configured by RRC.

[0552] Exemplarily, the RRC configuration is dedicated to resources within the window, such as a specific search space configuration, a specific control resource set (CORESET) configuration, a specific semi-persistent scheduling (SPS) configuration, a specific configuration grant (CG) configuration, a specific CSI-RS configuration, a specific SRS configuration, a specific PUCCH configuration, a specific downlink control signaling format (DCI) configuration, or a specific SSB configuration.

[0553] In some embodiments, the UE cannot send signaling related to communication with the IoT device within the window.

[0554] In some embodiments, within the window, the UE stops / terminates communication with the IoT device.

[0555] In some embodiments, the position of the window is determined by a timer. For example, the length of the timer is configured by signaling or predefined; the position of the window is determined by the timer, indicating that the window is activated when the timer expires.

[0556] In some embodiments, when the fourth condition is met, the timer is started / triggered / activated / reactivated.

[0557] The fourth condition includes at least one of the following:

[0558] The UE sends a second signaling;

[0559] The UE receives the first signaling;

[0560] Window ends;

[0561] Receiving a third signaling sent by the IoT device;

[0562] The UE sends feedback information to the base station;

[0563] The UE is activated as an intermediate node.

[0564] In some embodiments, the timer is started / triggered / activated / reactivated if the first condition is met.

[0565] In some embodiments, the window configuration of a UE in an active state is different from that of a UE in an idle / inactive state.

[0566] In some embodiments, different first signaling triggers different window configurations.

[0567] In some embodiments, the configuration information of the window is related to at least one of the following:

[0568] Measurement Gap configuration;

[0569] Configuration of SSB;

[0570] CSI-RS configuration;

[0571] Configuration of CSI reporting location;

[0572] SPS Configuration

[0573] CG configuration.

[0574] Example 5

[0575] The communication between the UE and the IoT device and the communication between the UE and the base station can be carried out simultaneously.

[0576] The communication between the UE and the IoT device includes at least one of the following: first signaling, second signaling, third signaling, and fourth signaling.

[0577] In some embodiments, the communication between the UE and the IoT device includes second signaling and third signaling.

[0578] The uplink signaling for communication between the UE and the base station includes at least one of the following: SR, BSR, CSI report, Hybrid Automatic Repeat Request (HARQ) feedback information, PUCCH, Msg1, Msg3, data PUSCH of dynamic grant (DG), configuration grant (CG) PUSCH, etc.

[0580] The uplink signaling between the UE and the base station is the signaling sent by the UE to the base station. The downlink signaling between the UE and the base station is the signaling sent by the base station to the UE.

[0581] In some embodiments, when the second signaling conflicts with uplink signaling between the UE and the base station, the UE sends the communication signaling between the UE and the base station and does not send or postpones sending the second signaling. That is, the priority of the uplink signaling between the UE and the base station is greater than / higher than the priority of the second signaling.

[0582] In some embodiments, the conflict indicates that a sending timing of the second signaling overlaps with a sending timing of an uplink signaling for communication between the UE and the base station in the time domain.

[0583] In some embodiments, the conflict indicates that the sending resource of the second signaling overlaps with the sending resource of the uplink signaling for communication between the UE and the base station.

[0584] In some embodiments, when the second signaling conflicts with uplink signaling communicated between the UE and the base station, the UE sends a signaling with a higher priority.

[0585] Lower-priority signaling is deferred or not transmitted. For example, HARQ (ACK / NACK) > second signaling. For example, DG PUSCH > second signaling. For example, second signaling > periodic / semi-persistent CSI report. For example, second signaling > CSI report. For example, second signaling > SR / BSR. For example, Msg1 / Msg3 > second signaling.

[0586] In some embodiments, when the third signaling conflicts with downlink signaling communicated between the UE and the base station, the UE monitors / receives the third signaling.

[0587] In some embodiments, the conflict indicates that the monitoring / receiving timing of the third signaling overlaps with the monitoring / receiving timing of the downlink signaling communicated between the UE and the base station.

[0588] In some embodiments, the conflict indicates that the monitoring / receiving resources of the third signaling overlap with the monitoring / receiving resources of the downlink signaling communicated between the UE and the base station.

[0589] In some embodiments, when the third signaling conflicts with the downlink signaling communicated between the UE and the base station, the UE monitors / receives the downlink signaling / signal communicated between the UE and the base station.

[0590] In some embodiments, when the third signaling conflicts with downlink signaling communicated between the UE and the base station, the UE monitors / receives the signaling / signal with a higher priority.

[0591] Low-priority signaling is not received or monitored. For example, the third signaling > CSI-RS. For example, the third signaling > periodic or semi-persistent CSI-RS. For example, the third signaling > newly transmitted DCI. For example, the third signaling > DCI transmitted in Type 3 search space (SS). For example, retransmitted DCI > the third signaling. For example, DCI transmitted in Type 0, 1, 2, or 0A SS > the third signaling. For example, the third signaling > SSB. For example, SSB > the third signaling. For example, signaling carrying system information > the third signaling.

[0592] In some embodiments, when the communication between the UE and the IoT device conflicts with the communication between the UE and the base station, the UE communicates with the base station, the UE does not communicate with the IoT device, or the UE postpones communication with the IoT device.

[0593] In some embodiments, when the communication between the UE and the IoT device conflicts with the communication between the UE and the base station, the UE communicates with the IoT device, the UE does not communicate with the base station, or the UE postpones the communication with the base station.

[0594] In some embodiments, when the signaling of the communication between the UE and the IoT device conflicts with the signaling of the communication between the UE and the base station, the UE communicates with the signaling with higher priority based on the priority.

[0595] Conflict means that signaling transmission opportunities or signaling transmission resources overlap.

[0596] The priority setting can be the priority sorting mentioned above.

[0597] Priorities can also include:

[0598] For example, HARQ (ACK / NACK) > third signaling. For example, DG PUSCH > third signaling. For example, third signaling > periodic / semi-persistent CSI reporting. For example, third signaling > CSI reporting. For example, third signaling > SR / BSR. For example, Msg1 / Msg3 > third signaling.

[0599] For example, the second signaling > CSI-RS. For example, the second signaling > periodic or semi-persistent CSI-RS. For example, the second signaling > newly transmitted DCI. For example, the second signaling > DCI transmitted in a Type 3 search space (SS). For example, retransmitted DCI > the second signaling. For example, DCI transmitted in a Type 0, 1, 2, or 0A SS > the second signaling. For example, the second signaling > SSB. For example, SSB > the second signaling. For example, signaling written to system information > the second signaling.

[0600] For example, HARQ (ACK / NACK) > signaling between UE and IoT devices. For example, DG PUSCH > signaling between UE and IoT devices. For example, signaling between UE and IoT devices > periodic / semi-persistent CSI reporting. For example, signaling between UE and IoT devices > CSI reporting. For example, signaling between UE and IoT devices > SR / BSR. For example, Msg1 / Msg3 > signaling between UE and IoT devices.

[0601] For example, signaling between the UE and IoT devices > CSI-RS. For example, signaling between the UE and IoT devices > periodic or semi-persistent CSI-RS. For example, signaling between the UE and IoT devices > newly transmitted DCI. For example, signaling between the UE and IoT devices > DCI transmitted in Type 3 search space (SS). For example, retransmitted DCI > signaling between the UE and IoT devices. For example, DCI transmitted in Type 0, 1, 2, 0A SS > signaling between the UE and IoT devices. For example, signaling between the UE and IoT devices > SSB. For example, SSB > signaling between the UE and IoT devices. For example, signaling written to system information > signaling between the UE and IoT devices.

[0602] For example, the signaling communicated between the UE and the base station > the second signaling. For example, the signaling communicated between the UE and the base station > the third signaling. For example, the second signaling > the signaling communicated between the UE and the base station.
