Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to a method and apparatus for information transmission and a communication device. Background Art

[0002] 3GPP has defined a new type of Internet of Things (IoT) device, namely Ambient Internet of Things (A-IoT), for low-end IoT devices with low complexity, low cost, and low power consumption. A-IoT devices do not have or only have limited power supply, and are characterized by low energy consumption and low cost. A-IoT includes three types of devices: Device A, Device B, and Device C. Among them, Device A and Device B do not have or have limited power supply and do not have the ability to communicate actively. They can only backscatter the received signals and carry information in the backscattered signals. Device C can send signals actively. Due to the characteristics of low power consumption, low complexity, and no or limited power supply of A-IoT devices, the signals and procedures for access and paging in the existing New Radio (NR) system cannot be used for the communication scenarios of current A-IoT devices.

Rather, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner.

[0139] The following briefly describes the related concepts mentioned in the present application as follows.

[0140] 1. Backscatter communication

[0141] A backscatter (or backscattering) communication system consists of an excitation signal source and a signal reflection device, generally composed of a reader and a reflection tag. The reader is used to generate a radio frequency excitation signal, and the reflection tag is composed of devices that can reflect radio frequency signals. The reader sends a radio frequency signal to the reflection tag, and the reflection tag receives the signal sent by the excitation signal source and reflects the radio frequency signal. By changing the load impedance of the reflection tag antenna, information is modulated into the backscattered signal. When the reflection coefficient is configured as the first reflection coefficient, the energy of the excitation signal is completely absorbed by the tag antenna; when the reflection coefficient is configured as the second reflection coefficient, the excitation signal is completely reflected; when the reflection coefficient is configured as the third reflection coefficient, the excitation signal is partially absorbed and partially reflected.

[0142] 2. Possible receiver architectures for A-IoT

[0143] For A-IoT devices, due to their extremely simple receiver structures, they may only include some simple receiver components, such as a receiver architecture based only on On-Off Keying (OOK) signals; limited by the fact that the receiver cannot perform Inverse Fast Fourier Transform (IFFT) / Fast Fourier Transform (FFT) operations, A-IoT devices cannot complete the reception and processing of the configuration parameters for access and paging, and thus cannot complete the access and paging processes;

[0144] 3. New Radio (NR) Random Access

[0145] Through random access in the NR system, the base station will allocate a unique identity for the User Equipment (UE, also known as the terminal or terminal device), and at the same time, it can also learn which terminal devices are accessing. The random access process includes:

[0146] A. The UE sends a random access preamble sequence (i.e., Message 1, Msg1) on the Physical Random Access Channel (PRACH);

[0147] B. The UE receives a Random Access Response (RAR) message (i.e., Message 2, Msg2) on the Physical Downlink Control Channel (PDCCH) / Physical Downlink Shared Channel (PDSCH);

[0148] C. The UE sends Message 3 (Msg3) on the Physical Uplink Shared Channel (PDSCH);

[0149] D. The UE receives a contention resolution message (i.e., Message 4, Msg4) on the PDSCH channel.

[0150] Before the random access process, the terminal obtains a set of Synchronization Signal / PBCH block (SSB) indices, physical layer time-frequency resources, random access preamble sequence format, and parameters of the random access preamble sequence set through the system broadcast message. Then, the UE generates a random access preamble sequence based on the obtained information and initiates random access on the corresponding physical layer random access time-frequency resources.

[0151] The base station detects the PRACH. If the base station detects a Preamble sequence, it feeds back the corresponding random access response (RAR) information on the PDCCH / PDSCH. After the terminal sends the random access Preamble sequence, it detects the RAR information fed back on the downlink PDCCH / PDSCH within a RAR time window. If the corresponding RAR information is detected, it indicates that the random access Preamble sequence sent by the UE is detected by the base station. The RAR information also includes the uplink timing advance adjustment amount for this UE. The terminal can obtain uplink synchronization based on this adjustment amount, and then can send an uplink resource scheduling request message to perform subsequent data transmission.

[0152] Furthermore, the random access process further includes:

[0153] A. The terminal sends Message 1, which contains not only the random access Preamble sequence but also uplink data;

[0154] B. The base station sends Message 2, which contains not only the random access Preamble identifier and the timing advance command word (TAC), but also the UE ID or the cell radio network temporary identifier (Cell Radio Network Temporary Identifier, C-RNTI) for contention resolution;

[0155] 4. NR paging process

[0156] In the NR system, the base station locates the terminal through paging, can detect the reachability of the UE, and implement the following, including: triggering the UE radio resource control (RRC) connection establishment process, triggering UE RRC recovery, notifying the UE to update the system message or receive earthquake and tsunami warning (ETWS) / commercial mobile alert service (CMAS) notifications. There are two paging trigger methods in NR, core network trigger and base station trigger.

[0157] First, the standard defines the monitoring of paging in the Radio Resource Control idle or inactive (RRC-Idle / Inactive) state. The UE calculates the positions of the paging frame (PF) and paging occasion (PO) according to the parameter configuration. At the PO moment, the UE monitors the downlink control information (DCI) scrambled by the paging radio network temporary identifier (Paging-RNTI, P-RNTI) in the paging search space (Search Space, SS), then performs demodulation and decoding to obtain the physical downlink shared channel (PDSCH) carrying the paging message. After demodulating and decoding the PDSCH, the UE obtains the list information of UEs that have sent the paging message, queries the list, and if the UE is in the list, it obtains the paging message carried by the PDSCH; otherwise, the UE does not obtain the paging message.

[0158] Secondly, for the monitoring of the physical downlink control channel (PDCCH) of paging, it is scrambled by the P-RNTI, which is shared by all UEs. The base station configures the monitoring period, the number of paging radio frames in each period, and the number of POs in each paging radio frame. At the PO moment, the UE needs to listen for paging.

[0159] Furthermore, considering the multiple antennas of the NR system, for paging transmission and reception, multi-beam transmission and reception need to be considered.

[0160] In the prior art, random access in NR is achieved through the random access channel (RACH). Specifically:

[0161] 1) For random access and paging, in the NR system, the relevant random access and paging parameters are configured through broadcast message system information block (SIB), or base station configuration, or radio resource control (RRC) signaling, or dynamic signaling.

[0162] 2) In the RACH process, first, the terminal needs to send information to the base station through the UL preamble. The UL preamble sequence needs to be mapped to some resource blocks (RBs) and symbols in the UL and then sent to the base station after passing through the IFFT. However, for A-IoT, Devices A / B cannot send signals actively and must rely on the sending node (e.g., the base station) to send the excitation signal first before they can send signals through reflection, that is, A-IoT cannot send the Preamble signal actively. For Device C, since the maximum power consumption supported by the device is no higher than 1 mw or 10 mw, complex device components cannot be supported, thus the transmission performance cannot be guaranteed. Therefore, in the UL preamble transmission process of the traditional NR random access, A-IoT devices cannot support it or cannot guarantee the performance.

[0163] 3) In the RACH process, second, the base station needs to send DL control information and data information through the DL PDCCH channel and PDSCH channel. On the receiving side, the UE needs complex receiving and sending components to complete the blind detection of the PDCCH channel and the demodulation and decoding of the data channel. For example, complex radio frequency receiving components, baseband processing components, local oscillators, and accurate time-frequency offset synchronization modules. However, for A-IoT, Devices A and B must rely on the excitation signal sent by the base station to send information through reflection. Even for Device C, for the receiver part, due to the limited power consumption requirements, there are no complex radio frequency components such as low noise amplifiers (LNAs), mixers, intermediate frequency processing, baseband FFT, and IFFT components, so the reception and processing of the PDCCH channel and PDSCH channel cannot be completed.

[0164] 4) In the RACH process, for the NR system, the UE needs to obtain the UE-ID and UL TA for subsequent accurate synchronization and communication with the base station. However, for A-IoT, first, due to its characteristics, it cannot achieve accurate synchronization or has no requirement for accurate synchronization. That is, for A-IoT, the functional characteristics of its random access are also significantly different from those of the NR system's random access function.

[0165] 5) Paging process. For the NR system, the paging trigger condition is when the network has signaling or data (including system messages, emergency messages, advertisement messages, etc.) to send to the UE, but the UE's state is not the radio resource control connected (RRC-connected) state. At this time, the network side cannot directly send data to the UE, and the network doesn't even know the specific location of the UE. At this moment, the network side needs to initiate paging. The paging action is that the network side or the base station side sends a Paging message, and the Paging message contains the UE-ID identifier, which means which user this paging message is for. For A-IoT, there are no multiple RRC states. At the same time, A-IoT doesn't need to receive various RRC-configured system messages, emergency messages, or advertisement messages. Therefore, the existing complex Paging signaling processing flow of NR is not applicable to A-IoT;

[0166] Based on the above problems, the current random access process and paging in the NR system are not applicable to A-IoT devices. Therefore, further design of the random access and paging for A-IoT devices is needed. The present invention provides a method to solve the low-power consumption requirement, low-complexity requirement, and low-end A-IoT devices to complete the random access and paging of A-IoT in the case of simple receiving and sending links.

[0167] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0304] Next, taking the communication between a base station and an A-IoT device as an example, the specific application of the embodiments of the present application will be described as follows.

[0305] It should be noted that, in the following example, the base station sends a query signal, and the query signal corresponds to the above-mentioned target signal.

[0306] Application Scenario 1: The base station completes access and / or paging through at least one query signal

[0307] Specifically, the process includes the following:

[0308] Step S11: The base station sends the configuration information of at least one access parameter through the first query signal;

[0309] Optionally, in this case, the first query signal includes at least one of the following: the resource location for sending the first query signal, the resource location for receiving the query signal. Optionally, the resource location can be agreed upon by the protocol or obtained by the base station and / or the A-IoT device through calculation.

[0310] The first query signal includes at least one of the following: excitation signal, energy harvesting signal, energy storage information, information collection indication information, reference signal transmission indication information, synchronization information, timing information, packet information, function classification information, application scenario information, priority information, access parameter configuration, access parameter information, paging parameter configuration, paging parameter information, base station information, A-IoT device information, A-IoT device grouping information, activation signaling, deactivation signaling, the threshold of the A-IoT device reflection response signal, the threshold of the A-IoT device sending the response signal, confirmation information.

[0311] The sending nodes of the following signals can be the same sending node or different sending nodes, including: the sending node of the excitation signal, the energy harvesting signal, the energy storage signal, the synchronization information or the timing information, the query signal carrying other or remaining functions; for example, the sending node of the query signal carrying other functions is the first sending node, and the sending node of the excitation signal can be the second sending node;

[0312] It should be noted that the access mentioned in this application refers to completing the connection between the base station and the A-IoT device so that data and information can be exchanged between the base station and the A-IoT device; for the A-IoT devices of device A and device B, the access can be initiated by the base station, that is, it can be initiated by the sending node of the query signal or the sending node of the excitation signal; for the A-IoT devices of device C type, the access can be initiated by the base station, that is, it can be initiated by the sending node of the query signal, or the sending node of the excitation signal, or can be initiated by the A-IoT device; if the access is initiated by the A-IoT device, the parameters for the A-IoT device to initiate the access are indicated by the query signal or agreed upon by the protocol.

[0313] The connection between the base station and the A-IoT device is completed, including at least one of the following configurations: the base station learns the parameters and information of the A-IoT device. For example, the identifier of the A-IoT, the type of the A-IoT device, the functional classification it can support, and the timing advance of the signal reflected or sent by the A-IoT; the A-IoT device learns the parameters and information of the base station. For example, the identifier of the base station, optionally including synchronization information and / or timing information, the time-frequency resource configuration for the A-IoT to reflect or send response information, and the location information of the time-frequency resource for the A-IoT to receive the query signal sent by the base station.

[0314] It should be noted that the paging mentioned in this application refers to the process initiated by the base station to complete the connection between the base station and the A-IoT device, enabling data and information interaction between the base station and the A-IoT device. The specific access process is not elaborated here.

[0315] Optionally, this step is an optional step. For example, for A-IoT devices such as Device A and Device B that do not have storage capabilities, sending configuration information to such A-IoT devices may not be very meaningful. Therefore, step S11 may not be executed for this type of A-IoT device.

[0316] Step S12: The base station uses a second query signal to instruct the first A-IoT device or the first group of A-IoT devices to reflect or send a first response signal.

[0317] Optionally, the second query signal can be the same as the first query signal. In this case, it means that the first query signal is used not only to instruct the configuration information of at least one access parameter but also to instruct the first A-IoT device or the first group of A-IoT devices to reflect or send a first response signal. In terms of the sending timing, it can be that the first query signal is sent at the first moment and is used to instruct both step S11 and step S12 (i.e., one query signal instructs two instructions simultaneously); or it can be that the first query signal is sent at the first moment to instruct step S11, and the first query signal is sent at the second moment to instruct step S12 (i.e., one query signal instructs different instructions at different times).

[0318] It should be noted that the sending nodes of the first query signal and the second query signal can be the same sending node or different sending nodes.

[0319] The response signal includes the A-IoT device responding with corresponding information according to the indication of the second query signal. For example, it includes at least one of the following: A-IoT device information, confirmation information, uplink data information (i.e., data, information, and / or signals sent by the A-IoT device). Optionally, the A-IoT device information, for example, can be the identifier of the A-IoT, the group identifier of the A-IoT; the uplink data information includes the data transmitted by the A-IoT in UL transmission. For example, data sensed by a sensor, reference signals sent by the A-IoT, and other information transmitted by the A-IoT.

[0320] The resource location where the A-IoT device sends the response signal: indicated by the second query signal, or configured by the base station (for example, for type C A-IoT devices), or predetermined by the protocol (indicated by predefined rules).

[0321] Step S13: The base station uses a third query signal to instruct the A-IoT device to reflect or send a second response signal;

[0322] Optionally, the third query signal can be the same as the first query signal. In this case, it means that the first query signal is used to indicate the configuration information of at least one access parameter, and is also used to instruct the A-IoT device or A-IoT device group to reflect or send a first response signal, and is also used to instruct the A-IoT to reflect or send a second response signal; in terms of the transmission timing, it can be that the first query signal is sent at the first moment and is used to indicate the content indicated by the query signals in steps S11, S12, and S13; or it can be that the first query signal is sent at the first moment to indicate step S11, the first query signal is sent at the second moment to indicate step S12, and the first query signal is sent at the third moment to indicate step S13.

[0323] Optionally, the third query signal can be the same as the second query signal. In this case, it means that the second query signal is used to instruct the A-IoT device or A-IoT device group to reflect or send a first response signal, and is also used to instruct the A-IoT device to reflect or send a second response signal; in terms of the transmission timing, it can be that the second query signal is sent at the first moment and is used to indicate steps S12 and S13 simultaneously; or, the second query signal is sent at the first moment to indicate step S12, and the second query signal is sent at the second moment to indicate step S13.

[0324] The indication that the A-IoT reflects or transmits a first response signal, or a second response signal, may include: indicating that the A-IoT reflects or transmits a first response signal, where the first response signal includes an indication that the A-IoT device or the A-IoT device group reflects or transmits acknowledgment information; the transmission timing includes at least one of the following: transmitting the first response signal at a fourth moment, transmitting the second response signal at a fifth moment; or at the fourth moment, transmitting the first response signal and the second response signal, or at the first moment, transmitting the second response signal.

[0325] Optionally, the first response signal includes at least one of the following: A-IoT device identification information, A-IoT device group identification information, identification information assigned by the base station to the A-IoT device, base station identification information, acknowledgment information.

[0326] Step S14: The A-IoT device receives the query signal sent by the base station and transmits at least one response signal through backscattering or directly.

[0327] For example, as Figure 3 shown, the specific timing for access and paging through one query signal and response signal is as follows: The base station sends a first query signal, the A-IoT device receives the first query signal, demodulates and decodes the first query signal, the A-IoT device queries the pre-stored (pre-defined) response information in the memory according to the decoded information, sends a response signal to the base station, and the base station receives the response signal sent by the A-IoT device.

[0328] For example, as Figure 4 shown, the specific timing for access and paging through multiple query signals and response signals is as follows: The base station sends a first query signal, the A-IoT device receives the first query signal, demodulates and decodes the first query signal, the A-IoT device queries the pre-stored (pre-defined) response information in the memory according to the decoded information, sends a first response signal to the base station, the base station receives the first response signal sent by the A-IoT device and sends a second query signal to the A-IoT device, indicating that the A-IoT device sends a second response signal; the A-IoT device receives the second response signal, demodulates and decodes it, obtains the indication information, and reflects the second response signal according to the obtained information, and the base station receives the second response signal sent by the A-IoT device.

[0329] Application scenario two: The base station completes energy harvesting and / or energy storage, access and / or paging through at least one query signal.

[0330] Step S21: The base station sends a radio frequency signal through a first signal for energy harvesting and / or energy storage (or storage) of the A-IoT device.

[0331] The first signal includes at least radio frequency energy harvesting and / or energy storage.

[0332] Step S22: The base station sends the configuration information of at least one access parameter through a first query signal.

[0333] Optionally, the first query signal may be the same as the first signal. In this case, the base station indicates energy harvesting and / or energy storage through the first query signal, and indicates the configuration information of at least one access parameter.

[0334] Optionally, the timing relationship between the first signal and the first query signal may include at least one of the following: sending the first signal at a first moment to indicate energy harvesting and / or storage and to indicate the configuration information of at least one access parameter; sending the first signal at a first moment to indicate energy harvesting and / or storage, and sending the first query signal at a second moment to indicate the configuration information of at least one access parameter.

[0335] Step S23: The base station indicates that the A-IoT device or the A-IoT device group reflects or sends a first response signal through a second query signal.

[0336] Optionally, in one case, the base station indicates energy harvesting and / or storage, indicates the configuration information of at least one access parameter, and indicates that the A-IoT device or the A-IoT device group reflects or sends a first response signal through the first signal; optionally, in another case, the base station indicates the configuration information of at least one access parameter and indicates that the A-IoT device or the A-IoT device group reflects or sends a first response signal through the first query signal; optionally, in another case, the base station indicates that the A-IoT device or the A-IoT device group reflects or sends a first response signal through the second query signal; specifically, the sending timing is the same as that in Application Case 1 and will not be elaborated here.

[0337] Step S24: The base station indicates that the A-IoT reflects or sends a second response signal, including confirmation information, through a third query signal.

[0338] For the specific implementation process, reference can be made to Application Case 1 and will not be elaborated here.

[0339] Step S25: The A-IoT device receives the query signal sent by the base station and sends at least one response signal through backscattering.

[0340] For the specific implementation process, reference can be made to Application Case 1 and will not be elaborated here.

[0341] For example, as Figure 5As shown in the figure, the specific timing for access and paging through a query signal and a response signal is as follows: The base station sends a first query signal for energy harvesting or energy storage and configuration information containing at least one access parameter. The A-IoT device receives the first query signal, demodulates and decodes the first query signal. The A-IoT device queries the pre-stored (pre-defined) response information in the memory according to the decoded information, and sends a response signal to the base station. The base station receives the response signal sent by the A-IoT device.

[0342] For example, as Figure 6 shown, the specific timing for access and paging through multiple query signals and response signals is as follows: The base station sends a first query signal for energy harvesting or energy storage and configuration information containing at least one access parameter. The A-IoT device receives the first query signal, demodulates and decodes the first query signal. The A-IoT device queries the pre-stored (pre-defined) response information in the memory according to the decoded information, and sends a first response signal to the base station. The base station receives the first response signal sent by the A-IoT device, and sends a second query signal to the A-IoT device, instructing the A-IoT device to send a second response signal; The A-IoT device receives the second response signal, demodulates and decodes it, obtains the indication information, and reflects the second response signal according to the obtained information. The base station receives the second response signal sent by the A-IoT device.

[0343] Application Case 3: The base station completes synchronization, access, and paging through at least one query signal

[0344] Step S31: The base station uses a second signal for A-IoT device synchronization or timing;

[0345] The second signal includes at least A-IoT device synchronization and / or timing.

[0346] Step S32: The base station sends the configuration information of at least one access parameter through the first query signal;

[0347] Optionally, the first query signal can be the same as the second signal. In this case, the base station uses the first query signal to instruct the A-IoT device for synchronization and / or timing, and to indicate the configuration information of at least one access parameter.

[0348] Step S33: The base station instructs the A-IoT device or the A-IoT device group to reflect or send a first response signal through the second query signal;

[0349] For the specific implementation process, refer to Application Case 1, which will not be elaborated here.

[0350] Step S34: The base station instructs the A-IoT to reflect or send a second response signal through the third query signal, including confirmation information;

[0351] For the specific implementation process, refer to Application Scenario 1, which will not be elaborated here.

[0352] Step S35: The A-IoT device receives the query signal sent by the base station and sends at least one response signal through backscattering or directly.

[0353] For the specific implementation process, refer to Application Scenario 1, which will not be elaborated here.

[0354] For example, Figure 7 The specific timing sequence for access and paging through one query signal and one response signal is as follows: The base station sends a first query signal for A-IoT device synchronization or timing and containing configuration information of at least one access parameter. The A-IoT device receives the first query signal, demodulates and decodes the first query signal. The A-IoT device queries the pre-stored (pre-defined) response information in the memory according to the decoded information and sends a response signal to the base station. The base station receives the response signal sent by the A-IoT device.

[0355] For example, Figure 8 The specific timing sequence for access and paging through multiple query signals and response signals is as follows: The base station sends a first query signal for A-IoT device synchronization or timing and containing configuration information of at least one access parameter. The A-IoT device receives the first query signal, demodulates and decodes the first query signal. The A-IoT device queries the pre-stored (pre-defined) response information in the memory according to the decoded information and sends a first response signal to the base station.

The A-IoT device receives the second response signal, demodulates and decodes it, obtains the indication information, and reflects the second response signal according to the obtained information. The base station receives the second response signal sent by the A-IoT device.

[0356] Application Scenario 4: The base station completes energy harvesting and / or energy storage, synchronization, access, and paging through at least one query signal

[0357] Step S41: The base station sends a radio frequency signal through the first signal for energy harvesting and / or energy storage of the A-IoT device.

[0358] Step S42: The base station sends a radio frequency signal through the second signal for synchronization or timing of the A-IoT device.

[0359] Step S43: The base station sends the configuration information of at least one access parameter through the first query signal.

[0360] Step S44: The base station indicates an A-IoT device or an A-IoT device group to reflect or send a first response signal through a second query signal;

[0362] Step S46: The A-IoT device receives at least one query signal sent by the base station and sends response information or a response signal through backscattering.

[0363] It should be noted that this application scenario is a combination of Application Scenario 1, Application Scenario 2, and Application Scenario 3, which will not be elaborated here.

[0365] The base station sends a first query signal for energy harvesting or energy storage, A-IoT device synchronization or timing, and configuration information including at least one access parameter. The A-IoT device receives the first query signal, demodulates and decodes the first query signal. The A-IoT device queries the response information pre-stored (pre-defined) in the memory according to the decoded information and sends a response signal to the base station. The base station receives the response signal sent by the A-IoT device.

[0366] For example, as Figure 10 shown, the specific timing for access and paging through multiple query signals and response signals is as follows:

[0367] The base station sends a first query signal for energy harvesting or energy storage, A-IoT device synchronization or timing, and configuration information including at least one access parameter. The A-IoT device receives the first query signal, demodulates and decodes the first query signal. The A-IoT device queries the response information pre-stored (pre-defined) in the memory according to the decoded information and sends a first response signal to the base station. The base station receives the first response signal sent by the A-IoT device and sends a second query signal to the A-IoT device, indicating the A-IoT device to send a second response signal; The A-IoT device receives the second response signal, demodulates and decodes it, obtains the indication information, and reflects the second response signal according to the obtained information. The base station receives the second response signal sent by the A-IoT device.
