[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 2024101286300, filed on January 30, 2024, entitled “Signal Transmission Method and Apparatus,” which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to the field of communication technology, and in particular to a signal transmission method and device. Background Art

[0004] The 3rd Generation Partnership Project (3GPP) has defined a new type of Internet of Things (IoT) device, the Ambient Internet of Things (A-IoT). A-IoT devices are low-complexity, low-cost, and low-power, low-end IoT devices. A-IoT devices have no or limited power supply, and are characterized by low energy consumption and low cost. A-IoT includes three device types: Device A, Device B, and Device C. Device A and Device B have no or limited power supply and cannot actively communicate. They can only backscatter received signals, carrying information in the backscattered signals. Device C can actively send signals. Due to the low power consumption, low complexity, and no or limited power supply characteristics of A-IoT devices, the signals and processes used for access and paging in existing New Radio (NR) systems cannot be used in current A-IoT device communication scenarios. Therefore, for those skilled in the art, how to enable communication between A-IoT devices is a technical problem that needs to be solved. Summary of the Invention

[0093] In order to facilitate a clearer understanding of the technical solutions provided by the various embodiments of the present disclosure, some relevant knowledge is first introduced as follows.

[0094] 3GPP defines three types of A-IoT devices, including whether they have energy storage capabilities and independent signal transmission capabilities:

[0095] 1. A-IoT device types and characteristics

[0096] 3GPP divides A-IoT devices into the following three categories based on whether they have energy storage capabilities and independent signal generation capabilities:

[0097] Device A: No energy storage capability, no independent signal generation capability, and transmits signals via backscattering.

[0098] Device B: It has energy storage capability but no independent signal generation capability. It transmits signals via backscattering, and the stored energy can be used to amplify the power of the backscattered signal.

[0099] Device C: has energy storage capabilities, the ability to independently generate signals, and uses radio frequency devices for signal transmission.

[0100] 2. Backscatter communication

[0101] A backscatter communication system consists of an excitation signal source and a signal reflection device, generally consisting of a reader and a reflective tag. The reader generates the RF excitation signal, while the reflective tag is a device that reflects the RF signal. The reader transmits the RF signal to the reflective tag, which receives the signal from the excitation signal source and reflects the RF signal back to the tag. By varying the load impedance of the reflective tag antenna, information is modulated into the backscatter signal. When the reflection coefficient is configured to the first reflection coefficient, the energy of the excitation signal is completely absorbed by the tag antenna; when the reflection coefficient is configured to the second reflection coefficient, the excitation signal is completely reflected; and when the reflection coefficient is configured to the third reflection coefficient, the excitation signal is partially absorbed and partially reflected.

[0102] 3. Possible receiver architectures for A-IoT

[0103] For A-IoT devices, their receiver structures are extremely simple and may only include some simple receiver components, such as a receiver architecture based on on-off keying (OOK) signals. Due to the receiver's inability to perform inverse fast Fourier transform (IFFT) / fast Fourier transform (FFT) operations, A-IoT devices cannot complete the reception and processing of access and paging configuration parameters, and thus cannot complete the access and paging processes.

[0104] 4. New Radio (NR) random access

[0105] The NR system uses random access, and the base station will assign a unique identity to the user equipment (UE, also known as terminal or terminal device), and can also know which terminal devices are connected. The random access process includes:

[0106] A. The UE sends a random access preamble sequence (i.e., message 1, Msg1) on the physical random access channel (PRACH).

[0107] 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).

[0108] C. The UE sends message 3 (Msg3) on the physical uplink shared channel (PDSCH).

[0109] D. The UE receives a contention resolution message (i.e., message 4, Msg4) on the PDSCH channel.

[0110] Before performing the random access process, the terminal obtains the set of SS / PBCH block (Synchronization Signal / PBCH block, SSB) indexes, physical layer time-frequency resources, random access Preamble sequence format and random access Preamble sequence set parameters 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.

[0111] The base station detects the PRACH. If the base station detects the Preamble sequence, it will feedback the corresponding random access response (RAR) information on the PDCCH / PDSCH. After sending the random access Preamble sequence, the terminal detects the RAR information fed back on the downlink PDCCH / PDSCH within a RAR time window. If the corresponding RAR information is detected, it means that the random access Preamble sequence sent by the UE has been detected by the base station. The RAR information also includes the uplink timing advance adjustment amount of the UE. The terminal can achieve uplink synchronization based on this adjustment amount, and then can send an uplink resource scheduling request message for subsequent data transmission.

[0112] Furthermore, the random access process also includes:

[0113] A. The terminal sends Message 1, which contains not only the random access preamble sequence but also uplink data.

[0114] B. The base station sends Message 2, which includes the random access preamble identifier and timing advance command (TAC), as well as the UE ID or cell radio network temporary identifier (C-RNTI) used for contention resolution.

[0115] 5. NR paging process

[0116] In the NR system, the base station finds the terminal through paging, can detect the reachability of the UE, and implement the following, including: triggering the UE Radio Resource Control (RRC) link establishment process, triggering UE RRC recovery, and notifying the UE to update system information or receive Earthquake and Tsunami Warning (ETWS) / Commercial Mobile Alert Service (CMAS) notifications. There are two paging triggering methods in NR: core network triggering and base station triggering.

[0117] First, the standard defines the monitoring of paging under radio resource control idle or inactive (RRC-Idle / Inactive). The UE calculates the position of the paging frame (PF) and the paging opportunity (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 (SS), and then demodulates and decodes to obtain the PDSCH carrying the paging message. After demodulating and decoding the PDSCH, the UE list information for recording the UE that sent the Paging message is obtained, and the list is queried. If the UE is in the list, the Paging message carried by the PDSCH is obtained. Otherwise, the UE does not obtain the paging message.

[0118] Secondly, the monitoring of the PDCCH of paging is scrambled through P-RNTI. P-RNTI 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 monitor paging.

[0119] Furthermore, considering the multiple antennas, Paging transmission and reception of the NR system, it is necessary to consider multi-beam transmission and reception.

[0120] 6. Resource configuration method for NR transmission signals

[0121] The resource configuration method for NR transmission signals includes: static, semi-static, and dynamic resource configuration methods. The static resource configuration method may include a configuration method based on RRC signaling and a configuration method based on broadcast signaling; the configuration method based on dynamic signaling includes a configuration method based on dynamic scheduling signaling and MAC-CE signaling.

[0122] Among them, the broadcast signaling includes cell-level parameter configuration information, such as system frame number, subcarrier spacing configuration, SSB subcarrier offset configuration, DMRS-TypeA position configuration, PDCCH common control resource set (Control Resource SET, CORESET) configuration, cell barring configuration, intrafrequency selection configuration, and reserved bits;

[0123] The RRC signaling configuration method includes configuration through RRC information elements, further including DL and UL transmission resource location information configuration; including resource location information configuration for data transmission and / or control signaling transmission, resource location configuration for reference signal transmission, configuration of UE behavior parameters, etc. The UE behavior includes channel measurement, Radio Resource Management (RRM) measurement, etc.

[0124] The dynamic signaling configuration method includes configuration information of resource locations for DL ​​and UL dynamic transmission, for example, configuration information of resource locations for PDSCH and PUSCH data transmission.

[0125] 7. PRACH resource allocation method

[0126] The specific frequency domain location of the PRACH is signaled separately using 2 bits of signaling. The number of frequency division multiplexing (FDM) PRACH occasions within the same PRACH slot can be 1, 2, 4, or 8. The maximum value is 8 because FDM increases the number of available RO resources under SSB-to-RACH Occasion (RO) mapping conditions.

[0127] The specific configuration is based on the following parameters. The elements contained in each PRACH configuration table are as follows:

[0128] (1)PRACH configuration index (8-bit indication): 0-255;

[0129] (2)PRACH preamble format;

[0130] (3) Configuration period: {10, 20, 40, 80, 160} ms;

[0131] (4) SFN mod configuration period;

[0132] (5) For frequency bands below 6 GHz, subframe numbering is used;

[0133] (5-1) Based on 15KHz sub-carrier spacing (SCS), the granularity is 1ms;

[0134] (5-2) For short sequence and 30kHz SCS, the number of PRACH slots in a subframe can be 1 or 2;

[0135] When there is only one RACH slot, the second PRACH slot is used;

[0136] (5-3) For short sequence and 15kHz SCS, the number of PRACH slots in a subframe is 1;

[0137] (6) For frequency bands above 6 GHz, PRACH timeslot numbering is used;

[0138] (6-1) Based on 60kHz SCS, granularity is 0.25ms;

[0139] (6-2) For 120kHz SCS, the number of PRACH slots within 0.25ms can be 1 or 2;

[0140] When there is only one RACH slot, the second PRACH slot is used;

[0141] (7) For 60kHz SCS, the number of PRACH slots within 0.25ms is 1;

[0142] (7-1) Starting symbol index (short sequence is Msg1 SCS, long sequence is 15kHz);

[0143] (8) The number of time-domain PRACH occasions within a PRACH time slot.

[0144] In the prior art, NR random access is implemented through RACH, and the specific resource locations are configured using the aforementioned configuration methods and parameters. A-IoT, with its simple component structure and signal processing, cannot adopt NR or LTE, or the existing access procedures and corresponding access parameter resource configuration. Therefore, it is necessary to design access procedures and corresponding access resource configuration methods specifically for A-IoT devices.

[0145] Based on the above problems, the current random access process and paging of the NR system are not applicable to A-IoT devices; therefore, further design of random access and paging of A-IoT devices is needed; further, further resource configuration methods are needed. The present invention provides a method for solving the resource configuration method for completing A-IoT access and paging for low-power and low-complexity A-IoT devices with simple receiving and transmitting links.

[0146] FIG1 is a flow chart of a signal transmission method provided by an embodiment of the present disclosure. As shown in FIG1 , the embodiment of the application provides a signal transmission method, the execution subject of which may be an IoT device, such as an A-IoT device. The method includes:
