Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and more particularly, to a method and device in a wireless communication system. Background Art

[0002] To meet the increased demand for wireless data communication services since the deployment of 4G communication systems, efforts have been made to develop improved 5G or quasi-5G communication systems. Therefore, 5G or quasi-5G communication systems are also referred to as "beyond 4G networks" or "post-LTE systems."

[0003] 5G communication systems are implemented in higher-frequency (millimeter wave, mmWave) bands, such as the 60 GHz band, to achieve higher data rates. To reduce radio wave propagation losses and increase transmission distances, 5G communication systems utilize technologies such as beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antennas.

[0004] In addition, in the 5G communication system, system network improvements are being developed based on advanced small cells, cloud radio access networks (RAN), ultra-dense networks, device-to-device (D2D) communications, wireless backhaul, mobile networks, collaborative communications, coordinated multi-point (CoMP), and receiving-end interference cancellation.

[0005] In 5G systems, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) have been developed as advanced coding modulation (ACM), as well as filter bank multi-carrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA) as advanced access technologies.

[0048] Figure 1 An example wireless network 100 is shown in accordance with various embodiments of the present disclosure. Figure 1 The embodiment of the wireless network 100 shown in FIGURE 1 is for illustration only. Other embodiments of the wireless network 100 can be used without departing from the scope of this disclosure.

[0049] Wireless network 100 includes gNodeB (gNB) 101, gNB 102, and gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one Internet Protocol (IP) network 130, such as the Internet, a private IP network, or other data network.

[0050] Depending on the network type, other well-known terms such as "base station" or "access point" can be used instead of "gNodeB" or "gNB." For convenience, the terms "gNodeB" and "gNB" are used in this patent document to refer to network infrastructure components that provide wireless access to remote terminals. Also, depending on the network type, other well-known terms such as "mobile station," "subscriber station," "remote terminal," "wireless terminal," or "user device" can be used instead of "user equipment" or "UE." For convenience, the terms "user equipment" and "UE" are used in this patent document to refer to a remote wireless device that wirelessly accesses a gNB, whether the UE is a mobile device (such as a mobile phone or smartphone) or what is typically considered a stationary device (such as a desktop computer or vending machine).

[0051] gNB 102 provides wireless broadband access to network 130 for a first plurality of user equipment (UEs) within gNB 102's coverage area 120. The first plurality of UEs includes: UE 111, which may be located in a small business (SB); UE 112, which may be located in an enterprise (E); UE 113, which may be located in a WiFi hotspot (HS); UE 114, which may be located in a first residence (R); UE 115, which may be located in a second residence (R); and UE 116, which may be a mobile device (M) such as a cellular phone, wireless laptop, or wireless PDA. gNB 103 provides wireless broadband access to network 130 for a second plurality of UEs within gNB 103's coverage area 125. The second plurality of UEs includes UE 115 and UE 116. In some embodiments, one or more of gNBs 101-103 may be capable of communicating with each other and with UEs 111-116 using 5G, Long Term Evolution (LTE), LTE-A, WiMAX, or other advanced wireless communication technologies.

[0052] The dashed lines illustrate the approximate extents of coverage areas 120 and 125, which are shown as approximately circular for purposes of illustration and explanation only. It should be clearly understood that coverage areas associated with gNBs, such as coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the radio environment associated with natural and man-made obstacles.

[0053] As described in more detail below, one or more of gNB 101, gNB 102, and gNB 103 include a 2D antenna array as described in embodiments of the present disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 supports codebook design and structure for systems with 2D antenna arrays.

[0054] although Figure 1 One example of a wireless network 100 is shown, but Figure 1 Various changes may be made. For example, wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement. Furthermore, gNB 101 can communicate directly with any number of UEs and provide those UEs with wireless broadband access to network 130. Similarly, each gNB 102-103 can communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. Furthermore, gNBs 101, 102, and / or 103 can provide access to other or additional external networks, such as an external telephone network or other type of data network.

[0055] Figure 2a and Figure 2bExample wireless transmit and receive paths according to the present disclosure are shown. In the following description, transmit path 200 can be described as being implemented in a gNB (such as gNB 102), while receive path 250 can be described as being implemented in a UE (such as UE 116). However, it should be understood that receive path 250 can be implemented in a gNB and transmit path 200 can be implemented in a UE. In some embodiments, receive path 250 is configured to support codebook design and structure for systems with 2D antenna arrays as described in embodiments of the present disclosure.

[0056] The transmit path 200 includes a channel coding and modulation block 205, a serial-to-parallel (S-to-P) block 210, an N-point inverse fast Fourier transform (IFFT) block 215, a parallel-to-serial (P-to-S) block 220, an add cyclic prefix block 225, and an upconverter (UC) 230. The receive path 250 includes a downconverter (DC) 255, a remove cyclic prefix block 260, a serial-to-parallel (S-to-P) block 265, an N-point fast Fourier transform (FFT) block 270, a parallel-to-serial (P-to-S) block 275, and a channel decoding and demodulation block 280.

[0057] In the transmit path 200, the channel coding and modulation block 205 receives a set of information bits, applies coding (such as low-density parity check (LDPC) coding), and modulates the input bits (such as using quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM)) to generate a sequence of frequency-domain modulation symbols. The serial-to-parallel (S-to-P) block 210 converts (e.g., demultiplexes) the serial modulation symbols into parallel data to generate N parallel symbol streams, where N is the number of IFFT / FFT points used in the gNB 102 and UE 116. The N-point IFFT block 215 performs an IFFT operation on the N parallel symbol streams to generate a time-domain output signal. The parallel-to-serial block 220 converts (e.g., multiplexes) the parallel time-domain output symbols from the N-point IFFT block 215 to generate a serial time-domain signal. The add cyclic prefix block 225 inserts a cyclic prefix into the time-domain signal. The upconverter 230 modulates (such as upconverts) the output of the add cyclic prefix block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at baseband before being converted to an RF frequency.

[0058] The RF signal transmitted from gNB 102 arrives at UE 116 after traversing the wireless channel. UE 116 performs operations that are the inverse of those performed at gNB 102. Downconverter 255 downconverts the received signal to baseband frequency, and cyclic prefix removal block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. Serial-to-parallel block 265 converts the time-domain baseband signal into parallel time-domain signals. N-point FFT block 270 performs an FFT algorithm to generate N parallel frequency-domain signals. Parallel-to-serial block 275 converts the parallel frequency-domain signals into a sequence of modulated data symbols. Channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

[0059] Each of gNBs 101-103 may implement a transmit path similar to 200 for transmitting in the downlink to UEs 111-116 and may implement a receive path similar to 250 for receiving in the uplink from UEs 111-116. Similarly, each of UEs 111-116 may implement a transmit path 200 for transmitting in the uplink to gNB 101-103 and may implement a receive path 250 for receiving in the downlink from gNB 101-103.

[0060] Figure 2a and Figure 2b Each of the components in can be implemented using hardware alone, or a combination of hardware and software / firmware. As a specific example, Figure 2a and Figure 2b At least some of the components in the embodiment may be implemented in software, while other components may be implemented in configurable hardware or a mixture of software and configurable hardware. For example, FFT block 270 and IFFT block 215 may be implemented as configurable software algorithms, wherein the value of the number of points N may be modified according to the implementation.

[0061] Furthermore, although described as using FFT and IFFT, this is illustrative only and should not be construed as limiting the scope of the present disclosure. Other types of transforms can be used, such as discrete Fourier transform (DFT) and inverse discrete Fourier transform (IDFT) functions. It should be understood that for DFT and IDFT functions, the value of the variable N can be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of the variable N can be any integer that is a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0062] although Figure 2a and Figure 2b Examples of wireless transmit and receive paths are shown, but Figure 2a and Figure 2b Make various changes. For example, Figure 2a and Figure 2b The various components in can be combined, further subdivided, or omitted, and additional components can be added according to specific needs. Figure 2a and Figure 2b It is intended to illustrate examples of the types of transmit and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communications in a wireless network.

[0063] Figure 3a An example UE 116 is shown in accordance with the present disclosure. Figure 3a The embodiment of UE 116 shown in FIGURE 1 is for illustration only, and Figure 1 UEs 111-115 can have the same or similar configurations. However, UEs have a variety of configurations, and Figure 3a The scope of this disclosure is not limited to any particular implementation of the UE.

[0064] UE 116 includes an antenna 305, a radio frequency (RF) transceiver 310, transmit (TX) processing circuitry 315, a microphone 320, and receive (RX) processing circuitry 325. UE 116 also includes a speaker 330, a processor / controller 340, an input / output (I / O) interface 345, input device(s) 350, a display 355, and memory 360. Memory 360 includes an operating system (OS) 361 and one or more applications 362.

[0065] RF transceiver 310 receives incoming RF signals from antenna 305, transmitted by a gNB of wireless network 100. RF transceiver 310 downconverts the incoming RF signals to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to RX processing circuitry 325, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuitry 325 sends the processed baseband signal to speaker 330 (such as for voice data) or to processor / controller 340 (such as for web browsing data) for further processing.

[0066] The TX processing circuit 315 receives analog or digital voice data from the microphone 320, or other outgoing baseband data (such as network data, email, or interactive video game data) from the processor / controller 340. The TX processing circuit 315 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 310 receives the outgoing processed baseband or IF signal from the TX processing circuit 315 and up-converts the baseband or IF signal to an RF signal that is transmitted via the antenna 305.

[0067] The processor / controller 340 can include one or more processors or other processing devices and execute an OS 361 stored in the memory 360 to control the overall operation of the UE 116. For example, the processor / controller 340 can control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceiver 310, the RX processing circuitry 325, and the TX processing circuitry 315 in accordance with well-known principles. In some embodiments, the processor / controller 340 includes at least one microprocessor or microcontroller.

[0068] Processor / controller 340 is also capable of executing other processes and programs residing in memory 360, such as operations for channel quality measurement and reporting for systems with 2D antenna arrays as described in embodiments of the present disclosure. Processor / controller 340 is capable of moving data into or out of memory 360 as required by the executed processes. In some embodiments, processor / controller 340 is configured to execute applications 362 based on OS 361 or in response to signals received from a gNB or operator. Processor / controller 340 is also coupled to I / O interface 345, which provides UE 116 with the ability to connect to other devices such as laptops and handheld computers. I / O interface 345 serves as a communication path between these accessories and processor / controller 340.

[0069] Processor / controller 340 is also coupled to input device(s) 350 and display 355. An operator of UE 116 can input data into UE 116 using input device(s) 350. Display 355 can be a liquid crystal display or other display capable of presenting text and / or at least limited graphics (such as from a website). Memory 360 is coupled to processor / controller 340. A portion of memory 360 can include random access memory (RAM), while another portion of memory 360 can include flash memory or other read-only memory (ROM).

[0070] although Figure 3a An example of a UE 116 is shown, but it is possible to Figure 3a Make various changes. For example, Figure 3a The various components in can be combined, further subdivided, or omitted, and additional components can be added according to specific needs. As a specific example, processor / controller 340 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Moreover, although Figure 3a The UE 116 is shown configured as a mobile phone or smartphone, but the UE can be configured to operate as other types of mobile or stationary devices.

[0071] Figure 3bAn example gNB 102 according to the present disclosure is shown. Figure 3b The embodiment of the gNB 102 shown in FIGURE 1 is for illustration only, and Figure 1 Other gNBs can have the same or similar configurations. However, gNBs have a variety of configurations, and Figure 3b The scope of this disclosure is not limited to any particular implementation of a gNB. It should be noted that gNB 101 and gNB 103 can include the same or similar structure as gNB 102.

[0072] like Figure 3b As shown in FIG, gNB 102 includes multiple antennas 370a-370n, multiple RF transceivers 372a-372n, transmit (TX) processing circuitry 374, and receive (RX) processing circuitry 376. In some embodiments, one or more of the multiple antennas 370a-370n comprise a 2D antenna array. gNB 102 also includes a controller / processor 378, memory 380, and a backhaul or network interface 382.

[0073] RF transceivers 372a-372n receive incoming RF signals from antennas 370a-370n, such as signals transmitted by a UE or other gNB. RF transceivers 372a-372n downconvert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to RX processing circuitry 376, which filters, decodes, and / or digitizes the baseband or IF signals to generate processed baseband signals. RX processing circuitry 376 sends the processed baseband signals to controller / processor 378 for further processing.

[0074] The TX processing circuitry 374 receives analog or digital data (such as voice data, network data, email, or interactive video game data) from the controller / processor 378. The TX processing circuitry 374 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate processed baseband or IF signals. The RF transceivers 372a-372n receive the outgoing processed baseband or IF signals from the TX processing circuitry 374 and up-convert the baseband or IF signals into RF signals that are transmitted via the antennas 370a-370n.

[0075] The controller / processor 378 can include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 378 can control the reception of forward channel signals and the transmission of reverse channel signals via the RF transceivers 372a-372n, the RX processing circuitry 376, and the TX processing circuitry 374 in accordance with well-known principles. The controller / processor 378 can also support additional functionality, such as more advanced wireless communication functions. For example, the controller / processor 378 can perform blind interference sensing (BIS) procedures, such as those performed by a Blind Interference Sensing (BIS) algorithm, and decode received signals with interference signals subtracted. The controller / processor 378 can support any of a variety of other functions within the gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0076] The controller / processor 378 is also capable of executing programs and other processes resident in the memory 380, such as a basic OS. The controller / processor 378 is also capable of supporting channel quality measurement and reporting for systems having 2D antenna arrays as described in embodiments of the present disclosure. In some embodiments, the controller / processor 378 supports communication between entities such as web RTC. The controller / processor 378 is capable of moving data into or out of the memory 380 as needed by the executing processes.

[0077] The controller / processor 378 is also coupled to a backhaul or network interface 382. The backhaul or network interface 382 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or over a network. The backhaul or network interface 382 can support communication over any suitable wired or wireless connection(s). For example, when the gNB 102 is implemented as part of a cellular communication system (such as one supporting 5G or new radio access technology, or NR, LTE, or LTE-A), the backhaul or network interface 382 can allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the backhaul or network interface 382 can allow the gNB 102 to communicate over a wired or wireless local area network or with a larger network, such as the Internet, via a wired or wireless connection. The backhaul or network interface 382 includes any suitable structure that supports communication over a wired or wireless connection, such as an Ethernet or RF transceiver.

[0078] Memory 380 is coupled to controller / processor 378. A portion of memory 380 can include RAM, while another portion of memory 380 can include flash memory or other ROM. In some embodiments, a plurality of instructions, such as a BIS algorithm, are stored in the memory. The plurality of instructions are configured to cause controller / processor 378 to perform the BIS process and decode the received signal after subtracting at least one interfering signal determined by the BIS algorithm.

[0079] As described in more detail below, the transmit and receive paths of gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuitry 374, and / or RX processing circuitry 376) support aggregated communications with FDD cells and TDD cells.

As another specific example, while shown as including a single instance of TX processing circuitry 374 and a single instance of RX processing circuitry 376, the gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0081] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0082] The text and drawings are provided as examples only to help readers understand the present disclosure. They are not intended to, and should not be interpreted as, limiting the scope of the present disclosure in any way. Although certain embodiments and examples have been provided, it will be apparent to those skilled in the art based on what is disclosed herein that the embodiments and examples shown may be modified without departing from the scope of the present disclosure.

[0083] Within Long Term Evolution (LTE) technology, IoT technologies include Machine Type Communication (MTC) and Narrowband Internet of Things (NB-IoT). These two communication technologies offer low cost, low power consumption, high latency, wide coverage, and large-scale access, and are suitable for IoT scenarios such as smart cities, smart factories, and remote meter reading.

[0084] The Internet of Things (IoT) technology features low cost, low power consumption, and support for large-scale connections. It is often used in application scenarios such as smart factories, smart healthcare, and urban management that require a large number of devices and emphasize cost control, to achieve the communication effect of the Internet of Everything.

[0085] The methods by which IoT devices receive downlink signals and send uplink signals are different from traditional wireless communication methods. Ambient IoT (AIoT) devices are a type of low-cost, low-power, low-end IoT devices. In this application, since the transmission of such IoT devices mainly relies on environmental signals, such IoT devices are called ambient IoT devices. This name is mainly for the convenience of description and is not used to limit the scope of the device.

[0086] The methods of receiving downlink signals and sending uplink signals of environmental IoT devices are different from traditional wireless communication methods, so they cannot use the structure of uplink signals or channels or the structure of downlink signals or channels in cell communication for communication.

[0087] The present invention provides a method for designing signal and channel structures for low-end IoT devices, such as ambient IoT devices. This method enables communicating nodes to flexibly send one or more payload signals / channels in a single transmission. Furthermore, based on identification instructions, communicating nodes can flexibly send payload signals / channels to the same or different nodes in a single transmission. This allows ambient IoT devices to use this structure for both uplink and downlink communications, making signal / channel design more flexible and adaptable to different application scenarios, while reducing the waste of air interface resources and additional latency associated with sending multiple payload signals / channels in multiple transmissions.

[0088] In the AIoT system, the transmission of signals / channels such as data and services can be directly transmitted between the base station and the AIoT node (such as a tag device); it can also be transmitted through an intermediate node. For example, the base station sends information related to the AIoT system to the intermediate node, and the intermediate node sends data to the AIoT node; and the AIoT node sends data to the intermediate node, and the intermediate node then sends information related to the AIoT system to the base station.

[0089] In this specification, for the services in the AIoT system, a principle similar to that of traditional cell communications is adopted, and the transmission from the base station or intermediate node to the AIoT node is called downlink transmission, and the transmission from the AIoT node to the base station or intermediate node is called uplink transmission. In addition, the transmission related to the AIoT system sent by the base station to the intermediate node can also be called downlink transmission, and the transmission related to the AIoT system sent by the intermediate node to the base station can be called uplink transmission. Unless otherwise specified in this specification, the uplink / downlink transmission corresponds to the relationship between the transmitting and receiving nodes, and is not used to limit whether the transmission occurs on the uplink or downlink resources. For example, the uplink transmission in the AIoT system can also be sent and received on the downlink frequency band in the FDD system, and the downlink transmission in the AIoT system can also be sent and received on the uplink time slot in the TDD system.

[0090] The base station in this specification may also be replaced by other devices, such as a communication device as an external accessory of the base station, a relay node, an IAB node, a repeater node, and a bypass node. Any mechanism applicable to the base station in this specification may also be similarly used in scenarios where the base station is replaced by other nodes, and will not be repeated. Among them, the difference between the communication device of the external accessory of the base station and the base station may include: the device is capable of sending DL signals / channels on the UL frequency band in the FDD system and on the UL time unit in the TDD system, including sending DL signals / channels corresponding to communication between the base station and the UE and DL signals / channels corresponding to communication between the base station and the AIoT device.

[0091] The intermediate node in this specification may be at least one of a relay node, an IAB node, a repeater node, and a bypass node.

[0092] The UE in this specification includes a device node in the AIoT system, which can be a specific type of node or device, such as a tag-type device.

[0093] In the embodiment of the present application, lower than the threshold value can also be replaced by lower than or equal to the threshold value, higher than (exceeds) the threshold value can also be replaced by higher than or equal to the threshold value, less than or equal to can also be replaced by less than, greater than or equal to can also be replaced by greater than; and vice versa.

[0094] In the embodiments of the present application, unless otherwise specified, configuration information includes at least one of the following: information configured by the base station, information indicated in received signaling, information configured by a higher layer, and information pre-configured. Furthermore, the configuration information may be a set of configuration information obtained by the above method; or multiple sets of configuration information obtained by the above method, from which the UE or node may select a set of configuration information for use based on predefined conditions; or a set of configuration information obtained by the above method, where the set of configuration information includes multiple subsets, from which the UE or node may select a subset for use based on predefined conditions.

[0095] Due to their simple structure and fundamental communication principles that differ from traditional wireless communication methods, AIoT devices cannot usually be deployed and operated under traditional cell communications, requiring the design of a separate communication system. This specification provides a method for designing the signal and channel structure in a communication system. This method can include one or more payloads in a signal or channel, and can cause multiple payloads in the signal or channel to correspond to the same or different receiving nodes, thereby enhancing the flexibility of the communication system, reducing the additional overhead and latency of sending multiple payloads through multiple signals / channels, and making the system more efficient.

[0096] In this specification, unless otherwise specified, a signal structure includes a structure of an uplink signal and / or a channel, and / or a structure of a downlink signal and / or a channel.

[0097] Figure 4 A flowchart of a method performed by a UE according to various embodiments of the present disclosure is shown. At S401, at least one payload header is received in a downlink signal, wherein the at least one payload header includes information related to a UE identity. At S402, at least one payload corresponding to the at least one payload header is received in the downlink signal based on the information related to the UE identity.

At S501, at least one payload header in an uplink signal is determined, wherein the at least one payload header includes information related to an identity of an intermediate node and / or a base station. At S502, based on the information related to the identity of the intermediate node and / or the base station, an uplink signal is transmitted, wherein the uplink signal includes the at least one payload header and at least one payload corresponding to the at least one payload header.

[0099] Figure 6A flowchart of a method performed by a node according to various embodiments of the present disclosure is shown. At S601, at least one payload header in an uplink signal is received, wherein the at least one payload header includes information related to an identity of an intermediate node and / or a base station. At S602, based on the information related to the identity of the intermediate node and / or the base station, at least one payload corresponding to the at least one payload header included in the uplink signal is received.

[0100] Figure 7 A flowchart of a method performed by a node according to various embodiments of the present disclosure is shown. At S701, at least one payload header in a downlink signal is determined, the payload header including information related to a UE identity. At S702, based on the UE identity, a downlink signal is transmitted, the downlink signal including the at least one payload header and at least one payload corresponding to the at least one payload header.

[0101] Optionally, the UE identity includes at least one of the following: an identity of a UE, an identity of a UE group or a UE set, and a UE identity corresponding to all UEs (ie, corresponding to broadcast).

[0102] Optionally, in a wireless communication system, a signal structure includes: at least one payload header; and at least one payload. The payload header is used to indicate relevant information of the corresponding payload, such as the payload type, length, target UE identity, and other control information.

[0103] Optionally, according to preset and / or (pre)configured criteria, the at least one payload header and the at least one payload are in one-to-one correspondence. Optionally, according to preset and / or (pre)configured criteria, each payload header corresponds to one or more payloads; further, each payload header corresponds to multiple payloads of the same type, for example, multiple payloads used for random access request responses, multiple payloads used to indicate downlink data, or multiple payloads indicated as scheduling information for uplink data.

[0104] Figure 8a Schematically shows a signal structure including a payload header and a payload, wherein the payload header is located before the payload.

[0105] Figure 8b The figure schematically illustrates a signal structure including multiple payload headers and multiple payloads. The payload headers are located before and are continuous with the corresponding payloads; and a combination of one payload header and its corresponding payload is located before or after another combination.

[0106] Figure 8cAnother signal structure including multiple payload headers and multiple payloads is schematically shown in FIG. The payload headers are located before the corresponding payloads and may be discontinuous with the corresponding payloads; and all payload headers are located before all payloads.

[0107] Figure 8b and Figure 8c In the payload header and the number after the payload are used to identify the corresponding relationship.

[0108] Optionally, the signal structure also includes a payload header, which is used to indicate at least one of the following information: the identity (ID) of the UE receiving the signal structure, the number of payload headers, the length of the payload header, the type of payload header, the total length of the signal structure, the total length of the payload header and all payload headers, the total length of all payload headers, and the total length of all payloads. Optionally, the payload header is located at the starting position of the signal structure and / or before all payload headers and payloads. Optionally, this method is used when the signal structure includes multiple payload headers. Optionally, when the signal structure includes a payload header and / or includes a payload, the payload header is used to replace the payload header; and / or, when the signal structure includes a payload, the signal structure includes the payload header but does not include the payload header. The payload header may also be referred to as a pre-placed payload header. Optionally, there may be another payload header before the first payload header, which may be referred to as a payload header.

[0109] Optionally, the signal format of at least one of the payload header and / or the payload header in each embodiment of this specification is preset or (pre)configured.

[0110] Optionally, the signal structure further includes: a start indicator at its starting position and an end indicator at its ending position.

[0111] Optionally, the signal structure further includes: a payload header start indicator at the start position of at least one payload header, and / or at the start position of each payload header, and / or at the start position of all payload headers, and / or at the start position of the first payload header, and / or at the start position of the total payload header; this method can also be understood as the at least one payload header / total payload header starting with the payload header start indicator. The payload header start indicator at the start position of the total payload header and / or the start position of the first payload header can be a start indicator of the signal structure.

[0112] Optionally, the signal structure further includes: a payload header end indicator at the end position of at least one payload header, and / or at the end position of each payload header, and / or at the end position of all payload headers, and / or at the end position of the last payload header, and / or at the end position of the total payload header; the method can also be understood as the above-mentioned at least one payload header / total header ending with the payload header end indicator. Optionally, if a payload header end indicator exists at the end position of the last payload header, the indicator is used as the boundary position between the payload header and the payload; accordingly, at least one of the UE, the intermediate node, and the base station determines the last payload header in the signal structure by the position of the payload header end indicator, and / or determines whether the information following a payload header is another payload header or data.

[0113] Optionally, the signal structure also includes: a load start indicator at the starting position of at least one load, and / or at the starting position of each load, and / or at the starting position of all loads, and / or at the starting position of the first load; the method can also be understood as at least one of the above-mentioned loads starting with a load start indicator.

[0114] Optionally, the signal structure further includes: a payload end indicator at the end of at least one payload, and / or at the end of each payload, and / or at the end of all payloads, and / or at the end of the last payload; this method can also be understood as at least one of the payloads ending with the payload end indicator. The payload end indicator at the end of the last payload can be the end indicator of the signal structure.

[0115] For at least one of the above-mentioned signal structure start indicator, signal structure end indicator, payload header start indicator, payload header end indicator, payload start indicator, and payload end indicator, optionally, the indicator is a signal waveform having a signal structure different from the signal structures corresponding to information bits '0' and '1'; for example, the signal structure corresponding to information bit '0' is a low level of length x1 followed by a high level of length x2, and the signal structure corresponding to information bit '1' is a high level of length x3, the start indicator is a low level of length y1 followed by a high level of length y2, the end indicator is a low level of length y3 followed by a high level of length y4, and x1 is not equal to y1 and / or x2 is not equal to y2, and x1 is not equal to y3 and / or x2 is not equal to y4. Furthermore, different indicators among the above-mentioned multiple indicators may correspond to the same or different signal waveforms, for example, y1 is not equal to y3 and / or y2 is not equal to y4. Alternatively, the indicator may be a preset specific field, such as "000" or "111." Furthermore, different indicators among the aforementioned multiple indicators may correspond to the same or different specific fields. In an exemplary embodiment, the start and end indicators of the signal structure correspond to different signal waveforms, the start indicator of the payload header and the start indicator of the payload correspond to one sequence, and the end indicator of the payload header and the end indicator of the payload correspond to another sequence.

[0116] Optionally, the signal structure further includes: a synchronization signal sent at the start position of the signal structure; wherein the synchronization signal can be understood as part of the signal structure. Alternatively, the signal structure further includes: a synchronization signal sent before the start position of the signal structure; wherein the synchronization signal is not part of the signal structure. Figure 8d An example of the synchronization signal is schematically shown in FIG. This method can be used in combination with other signal structure related methods.

[0117] Optionally, when the signal structure includes a synchronization signal sent at the starting position of the signal structure, the synchronization signal may be sent before or after the start indicator of the signal structure. Optionally, when the signal structure includes a synchronization signal sent at the starting position of the signal structure or a synchronization signal sent before the starting position of the signal structure, the starting position of the signal structure does not include a start indicator, and / or the synchronization signal may be used to determine the starting position of the signal structure, that is, it plays the same role as the start indicator of the signal structure in a physical sense; accordingly, at least one of the UE, the intermediate node, and the base station determines the starting position of the signal structure and / or the components in the signal structure through the position of the synchronization signal, for example, the starting position of the synchronization signal is the starting position of the signal structure, and / or the starting position of the synchronization signal is the starting position of the first component in the signal structure, for example, the starting position of the payload header or the payload header.

[0118] Optionally, the signal structure further includes: a synchronization signal sent in the middle of the payload header, and / or in the middle of the payload, and / or between two payload headers, and / or between two payloads, and / or between the payload header and the payload. Figure 8e An example of the synchronization signal is schematically shown in FIG, wherein the synchronization signal is sent in the middle of the payload. In another example of the synchronization signal, the synchronization signal is sent between the payload header and the payload; further, the payload header and the payload may correspond or not correspond, and may be adjacent to each other, for example, in Figure 8b Between load-1 and load head-1 (the load head and the load are corresponding), or between load-1 and load head-2 (the load head and the load are not corresponding); for example, in Figure 8c In another example of the synchronization signal, the synchronization signal is sent between the two payload headers, for example, Figure 8c In another example of the synchronization signal, the synchronization signal is sent between two payloads, for example, Figure 8c is sent between payload-2 and payload-3.

[0119] In the above examples, although the payload and payload header, or the payload and payload, or the payload header and payload header are not physically adjacent after the synchronization signal is added, they are referred to as adjacent payload headers and payloads to describe their relationship from the perspective of their position. The adjacent payload headers and payloads can also be described as any payload header and a payload preceding or following it, i.e., the synchronization signal is sent between any payload header and a payload preceding or following it.

[0120] This method can be used in combination with other signal structure related methods. For example, a synchronization signal can be included before the start indicator identified in the figure and the starting position of the channel structure, or a synchronization signal can be included before the starting position of the signal structure.

[0121] Optionally, when the signal structure includes a synchronization signal sent in the middle of the payload header, and / or in the middle of the payload, and / or between the payload header and the payload, the part of the signal structure before the synchronization signal ends with a stop indicator, and / or the part after the synchronization signal starts with a continue indicator. Figure 8d An example when the signal structure includes a synchronization signal in the middle of the payload is schematically shown in FIG.

[0122] Optionally, the continue indicator has the same signal structure as at least one of the start indicator, payload header start indicator, and payload start indicator of the signal structure; further, when the synchronization signal is sent in the middle of the payload header, the continue indicator has the same signal structure as the payload header start indicator, and / or when the synchronization signal is sent in the middle of the payload and / or between the payload header and the payload, the continue indicator has the same signal structure as the payload start indicator. Optionally, the abort indicator has the same signal structure as at least one of the end indicator, payload header end indicator, and payload end indicator of the signal structure; further, when the synchronization signal is sent in the middle of the payload header and / or between the payload header and the payload, the abort indicator has the same signal structure as the payload header end indicator, and / or when the synchronization signal is sent in the middle of the payload, the continue indicator has the same signal structure as the payload end indicator. The advantage of this method is that it simplifies the design of channel detection and reduces system complexity. Alternatively, the continue indicator and / or the stop indicator have a different signal structure from various types of start and / or end indicators, so that the base station, the intermediate node and the UE can accurately identify whether the signal / channel is actually ended or temporarily stopped due to the synchronization signal, thereby better detecting the synchronization signal based on the indicator, and more easily resuming the continued reception of the signal / channel after detecting the synchronization signal rather than treating the subsequent signal / channel as a new transmission.

[0123] Optionally, when repetition is enabled in the system, and / or when at least one signal and / or channel in the system uses repetition, the at least one signal and / or channel is sent in a repeated form, including at least one of the following methods:

[0124] Each payload header / payload header / payload in the signal structure is sent in a repeated and continuous manner, for example, the payload header is repeated the first time - the payload header is repeated the second time - ... - the payload header is repeated the Nth time - the first payload header is repeated the first time - the first payload header is repeated the second time - ... - the last payload header is repeated the Nth time - the first payload is repeated the first time - the first payload is repeated the second time - ... - the last payload is repeated the first time - ... - the last payload is repeated the Nth time. The advantage is that each component in the signal structure is sent continuously and is easy to merge.

[0125] Each payload header and payload in a signal forms a combination, and each combination is sent repeatedly and continuously. For example, the payload header is repeated the first time - the payload header is repeated the second time - ... - the payload header is repeated the Nth time - the first payload header is repeated the first time - the first payload header is repeated the second time - ... - the first payload header is repeated the Nth time - the first payload is repeated the first time - the first payload is repeated the second time - ... - the first payload is repeated the first time - the second payload header is repeated the first time - the second payload header is repeated the second time - ... - the second payload header is repeated the Nth time - the second payload is repeated the first time - the second payload is repeated the second time - ...; the advantage is that the payload header itself mainly carries control information for receiving the payload, so the repeated transmission of the payload header and payload unit is a group of signals carrying data / service information. During the reception process, the part that is received first can be used directly, reducing latency.

[0126] Repetition is performed based on the channel structure. For example, the payload header repeats the first time - the first payload header repeats the first time - the second payload header repeats the first time - ... - the last payload repeats the first time - the payload header repeats the second time - the first payload header repeats the second time - ... This has the advantage that different repetitions of the same payload header / payload are spaced far apart, which can better average out fading and interference in the time domain, preventing multiple repetitions of the same payload header / payload from being affected by the same deep fade or interference signal, resulting in decoding failures.

[0127] Optionally, if the signal structure further includes a synchronization signal sent at the start position of the signal structure and / or a synchronization signal sent before the start position of the signal structure, when repetition is enabled in the system, and / or when at least one signal and / or channel in the system uses repetition, the at least one signal and / or channel is sent in a repeated form, including at least one of the following methods:

[0128] The synchronization signal is sent in a repeated form, and / or the payload channel is sent in a repeated form, and there is no payload channel and / or other synchronization signal between the repeated synchronization signals. The repetition of the payload channel can use the method in other embodiments mentioned above. A specific example is as follows Figure 9a As shown;

[0129] The synchronization signal is sent in a repeated form, and there is a payload channel corresponding to the synchronization signal between the repeated synchronization signals. Further, it includes at least one repetition of the payload channel corresponding to the synchronization signal. A specific example is Figure 9b When the repeated synchronization signals include multiple repetitions of the corresponding payload channels, the repetition of the payload channels can use the methods in other embodiments described above.

[0130] Optionally, if the signal structure further includes a synchronization signal sent in the middle of the payload header, and / or in the middle of the payload, and / or between the payload header and the payload, when repetition is enabled in the system, and / or when at least one signal and / or channel in the system uses repetition, the at least one signal and / or channel is sent in a repeated form, including at least one of the following methods:

[0131] Taking the starting position of the at least one signal and / or channel as a reference point or taking at least one synchronization signal sent in the at least one signal and / or channel as a reference point, after the reference point, when the time and / or the number of information bits continuously sent by the at least one signal and / or channel exceeds a threshold, sending a synchronization signal;

[0132] If the synchronization signal is located in the middle of the payload header and / or the middle of the payload, when the payload header and / or the payload are repeatedly sent, the synchronization signal is also sent in the middle of the repeatedly sent payload header and / or the payload;

[0133] If the synchronization signal is located between the payload header and the payload, when the payload header and / or payload before the synchronization signal is repeatedly sent, the synchronization signal is also sent after the end position of the repeatedly sent payload header and / or payload; and / or, when the payload header and / or payload after the synchronization signal is repeatedly sent, the synchronization signal is also sent before the starting position of the repeatedly sent payload header and / or payload.

[0134] Optionally, when repetition is enabled in the system, and / or when at least one signal and / or channel in the system uses repetition, the node that transmits the at least one signal and / or channel, and / or the node that schedules other nodes to transmit the at least one signal and / or channel, and / or the node that receives the at least one signal and / or channel needs to indicate information related to repetition and transmit the at least one signal and / or channel based on the information, and / or obtain information related to repetition and receive the at least one signal and / or channel based on the information. Optionally, this includes indicating and transmitting and / or obtaining and receiving in at least one of the following ways:

[0135] Indicated by at least one of an indicator and a signal prefix (preamble). The indicator includes at least one of a signal structure start indicator, a signal structure end indicator, a payload header start indicator, a payload header end indicator, a payload start indicator, and a payload end indicator. The signal prefix includes at least one of the following synchronization signals, or includes at least one of the following synchronization signals and at least one of the above indicators (further, at least one of the above indicators corresponding to the start): a synchronization signal sent at the start position of the signal structure, a synchronization signal sent in the middle of the payload header, a synchronization signal sent in the middle of the payload, a synchronization signal sent between two payload headers, a synchronization signal sent between two payloads, and a synchronization signal sent between the payload header and the payload;

[0136] Indicated by control information. Optionally, the method is used when the data corresponding to the control information uses repetition, or when the data corresponding to the control information uses repetition and the control information does not use repetition;

[0137] Indicated by the load header and / or the total load header. Optionally, this method is used when the load header and / or the total load header corresponds to a load that uses repetition, or when the load header and / or the total load header corresponds to a load that uses repetition and the load header and / or the total load header does not use repetition.

[0138] The information related to repetition includes at least one of the following: the number of repetitions and the type of repetition. The type of repetition further includes at least one of the following: bit-level repetition, linearly coded code chip-level repetition, and TB-level repetition. For example, bit-level repetition includes first repeating the first bit several times, then repeating the second bit several times, and so on. Chip-level repetition includes, after the information bits (which may be original information bits, original information bits encoded with forward error correction codes (FEC), information bits that have undergone bit / TB-level repetition, etc.) are linearly encoded, and the codeword corresponding to each information bit includes N chips, first repeating the first chip several times, then repeating the second chip several times, and so on; further, first performing chip-level repetition on the codeword corresponding to the first information bit, then performing chip-level repetition on the codeword corresponding to the second information bit, and so on.

[0139] Optionally, the above method also includes: indicating the number of repetitions of the at least one signal and / or channel by the number of repetitions of at least one of the indicator and the signal prefix. For example, if the transmission of the indicator uses repetition and the number of repetitions is n1, then the at least one signal and / or channel uses repetition and the number of repetitions is n2, and there is a preset and / or configured mapping relationship between n1 and n2. For example, n2=n1+offset, where the value of offset is configured / preset. For another example, the node is preset / configured with a correspondence between a set of n1 values and a set of n2 values, and the number of repetitions is indicated according to the preset / configuration. The method can also be further extended to indicate the number of repetitions of data and / or payload header and / or payload by the number of repetitions of at least one of the control information, the payload total header, and the payload header, and the specific method is similar to that through the indicator and / or signal prefix.

[0140] Optionally, the above method further includes: indicating the repetition type of the at least one signal and / or channel by the repetition type of at least one of an indicator and a signal prefix. For example, if the repetition type of the signal prefix is bit level, then the repetition type of the at least one signal and / or channel is bit level. For another example, if the repetition type of the signal prefix is bit level, then the repetition type of the at least one signal and / or channel is bit level or chip level, and one of the bit level or chip level can be further indicated by at least one of the control information, the payload header, and the payload header. The method can also be further extended to indicate the repetition type of the data and / or payload header and / or payload by the repetition type of at least one of the control information, the payload header, and the payload header, and the specific method is similar to that by the indicator and / or signal prefix.

[0141] Optionally, the method further includes: indicating repetition-related information of the data and / or payload header and / or payload via a field for indicating repetition-related information in at least one of the control information, the payload header, and the payload header. Optionally, at least one of the control information, the payload header, and the payload header indicates repetition-related information of the data and / or payload header and / or payload corresponding to the at least one item (e.g., data corresponding to the control information, the payload header and / or payload corresponding to the payload header, or the payload corresponding to the payload header); and / or indicates repetition-related information of other data and / or payload, and accordingly indicates information used to identify the data and / or payload header and / or payload, such as the logical channel ID corresponding to the payload header / payload, the order of the payload header / payload in the signal structure (e.g., the Mth payload header / payload), the resource location corresponding to the data (which can be indicated by a time-frequency offset from the resource where the control information is located), whether the payload header / payload / data is sent before or after a given synchronization signal, the type of service corresponding to the payload header / payload / data (e.g., inventory or command), and the identity of the receiving node corresponding to the payload header / payload / data. Among them, the given synchronization signal includes at least one of the following: a synchronization signal sent at the starting position of the signal structure, a synchronization signal sent in the middle of the payload header, a synchronization signal sent in the middle of the payload, a synchronization signal sent between two payload headers, a synchronization signal sent between two payloads, and a synchronization signal sent between the payload header and the payload.

[0142] For the signal structure in the system, the nodes that send and receive the signal structure need to be able to determine which parts of the signal structure are the payload header and which parts are the payload. If there is only one payload header or only one payload header in the signal structure, since the format used by the payload header and the payload header can be preset and / or (pre) configured (for example, configured in the broadcast channel), the node decodes the payload header / header through the format, and the remaining part is the payload. If multiple payload headers and multiple payloads are allowed in the signal structure, the node cannot determine it based on the format alone, but also needs to know how many payload headers there are in the signal structure or to which part of the channel structure the subsequent information after each payload header / payload ends belongs.

[0143] Therefore, optionally, when a signal structure includes a payload header, the payload header indicates the number of payload headers and / or payloads included in the signal structure. Optionally, this method is used when the system allows or configures that a signal structure can include a payload header, multiple payload headers, and multiple payloads; otherwise, it is not used.

[0144] Optionally, when the signal structure includes at least one payload header and at least one payload, the information bit indicating the end of the payload header in at least one payload header corresponds to another payload header or a corresponding payload. For example, the payload header includes a 1-bit field, and its two states are used to indicate that the subsequent signal is another payload header or a payload. Optionally, this method is used when the system allows or configures multiple payload headers and multiple payloads in the signal structure, otherwise it is not used. Optionally, when the payload header in the signal structure is located before the corresponding payload, and the corresponding payload can be discontinuous, and all payload headers are before all payloads, for example, similar to Figure 8c This method is used when the structure shown is specified, otherwise it is not used.

[0145] Optionally, when the signal structure includes at least one payload header and at least one payload, the end position of the last one in the payload header ends with a payload header end indicator. The indicator is used to enable at least one of the UE, the intermediate node, and the base station to distinguish whether the payload header has been fully transmitted and whether the payload is received after the indicator. Optionally, this method is used when the system allows or configures multiple payload headers and multiple payloads in the signal structure, otherwise it is not used. Optionally, when the payload header in the signal structure is located before the corresponding payload, and the corresponding payload can be discontinuous, and all payload headers are before all payloads, for example, similar to Figure 8c This method is used when the structure shown is specified, otherwise it is not used.

[0146] Optionally, when the signal structure includes at least one payload header and at least one payload, the end position of at least one or each payload ends with a payload end indicator. The indicator is used to enable at least one of the UE, the intermediate node, and the base station to distinguish whether the current payload has been transmitted and whether a new payload header and / or payload is received after the indicator. Optionally, this method is used when the system allows or configures multiple payload headers and multiple payloads in the signal structure, otherwise it is not used. Optionally, when the payload header in the signal structure is located before the corresponding payload, and is continuous with the corresponding payload, and a combination of a payload header and a corresponding payload is before or after another combination, for example, similar Figure 8b This method is used when the structure shown is specified, otherwise it is not used.

[0147] A single signal structure can include multiple payloads, each corresponding to data or services for different purposes. For example, it can include payloads for inventory and commands; another example is payloads for different inventory information data, such as usage status, age, usage history, and usage count. These payloads can be sent to the same or different nodes, for example, from a UE to multiple intermediate nodes, with different payloads corresponding to the reporting information corresponding to inventory requests from different intermediate nodes.

[0148] A signal structure may also include multiple payloads, each corresponding to a different UE. For example, during a random access process, multiple different UEs may send random access requests, and an intermediate node or base station may send random access response signaling. The signal structure used in this signaling may include multiple random access request responses, each corresponding to the random access requests from different UEs.

[0149] Therefore, when a node sends a signal / channel, it needs to indicate the corresponding receiving node in the signal structure used; when a node receives a signal / channel, it needs to determine whether to receive the signal / channel based on the information of the receiving node indicated in the signal structure used, and further, determine which loads in the signal structure used to receive the signal / channel.

[0150] In the following embodiments, the node includes at least one of a UE, an intermediate node, and a base station, and the identity includes at least one of an identity of a node, an identity of a node group or a node set, and an identity of a corresponding broadcast node.

[0151] Optionally, the signal structure includes at least one payload header, wherein the at least one payload header indicates the identity of the receiving node corresponding to its payload. When the signal structure includes multiple payload headers, each payload header may indicate the identity of the receiving node corresponding to its payload, i.e., different payload headers may indicate different identities. Furthermore, / or, one of the multiple payload headers may indicate the identities of the receiving nodes corresponding to all payloads, i.e., different payload headers may correspond to the same receiving node; wherein the one payload header may be the first of the multiple payload headers.

[0152] Optionally, when the signal structure includes a payload header, the payload header indicates the identities of all receiving nodes corresponding to the signal structure. Furthermore, the payload header indicates whether the payload of the signal structure corresponds to the same or different nodes. The indication may be indicated by a specific field (e.g., 1 bit) or indirectly. For example, at least one specific identity (which may be all '0' or the corresponding broadcast ID) is preset and / or (pre) configured to indicate that the payload of the signal structure of the identity corresponds to different nodes, and the remaining identities are preset and / or (pre) configured to indicate that the payload of the signal structure of the identity corresponds to the same node. If the payload corresponds to the same node, there is no field in the payload header indicating the identity of the receiving node to which the payload corresponds, or the node receiving the signal structure does not recognize the field in the payload header indicating the identity of the receiving node to which the payload corresponds; if the payload corresponds to different nodes, there is a field in the payload header indicating the identity of the receiving node to which the payload corresponds, and the node receiving the signal structure also needs to identify the indication in the payload header to determine the receiving node to which each payload corresponds.

[0153] Optionally, when a multicast identity is indicated in the payload header included in the signal structure, the identity indicated in the payload header may be the ID of the UE within the group corresponding to the multicast identity. The advantage of this method is that the group ID is typically shorter (compared to a common identity), which helps save signaling overhead.

[0154] Optionally, when the signal structure includes a payload header, the payload header indicates the identity of the node that sent the signal structure. Optionally, a payload header included in the signal structure indicates the identity of the node that sent the signal structure. When the signal structure includes multiple payload headers, one of the payload headers, such as the first payload header, may indicate the identity of the node that sent the signal structure, thereby saving the overhead of multiple indications.

[0155] Optionally, after the node receiving the signal / channel identifies the identity corresponding to the signal structure and / or payload according to at least one of the above methods, it determines whether it needs to receive the corresponding signal structure and / or payload based on whether the identity matches itself.

[0156] To improve system efficiency and capacity, the AIoT system considers introducing multiple access technology, allowing multiple UEs to initiate random access requests during a random access process, and for an intermediate node or base station to respond to multiple UEs. This scenario is a typical embodiment of a signal structure in which a signal / channel is sent to multiple nodes. The design of the signal structure in this process is described below with reference to specific embodiments.

[0157] Optionally, the random access process includes:

[0158] The intermediate node or base station sends a signaling for triggering a random access process;

[0159] Upon receiving the signaling, the UE is triggered to start the random access procedure and send a random access request on the resources used for random access requests.

[0160] The intermediate node or the base station sends a random access request response to at least one UE based on the received random access request;

[0161] The UE receives a random access request response. If the response is a response to the UE's own random access request, the UE sends random access information to the intermediate node or the base station. The random access information may carry more complete information than that in the random access request, for example, a random number generated based on the low bits of the UE ID in the random access request may be indicated, while the complete UE ID may be indicated in the random access information.

[0162] The intermediate node or base station receives the random access information of the UE and sends a random access information response to the UE; the information carried in the random access information response may carry the configuration information of the UE access system and / or the configuration information required for the UE to subsequently receive downlink channels and / or send uplink channels.

[0163] After obtaining the random access information response, the UE can send an uplink channel, such as an uplink channel carrying inventory information data, according to the information configured therein; and / or receive a downlink channel, such as a downlink channel carrying AIoT command data.

[0164] Optionally, during the random access process, information related to the random access process is configured in the signaling used to trigger the random access process, including at least one of the following: the location and / or size and / or quantity of resources used for at least one of the random access request, random access request response, random access information, and random access information response; and the identity range of the UE participating in the random access process.

[0165] Optionally, during the random access process, the intermediate node or the base station sends a random access request response signal, which includes N payloads, corresponding to the random access requests of N UEs respectively. Optionally, the N payloads correspond to a payload header, which indicates a preset UE identity corresponding to the random access request response or a corresponding broadcast UE identity. Optionally, the N payloads correspond to a payload header, each of which indicates a UE identity; wherein the UE identity can be determined based on the UE ID indicated in the random access request, and / or based on the UE ID of the node sending the random access request indicated in the payload header in the signal structure used by the random access request signal, and / or based on the resources used by the random access request. For the last method, a specific example is that the node is triggered to start a random access process, in which M resources for random access requests are configured, and each resource can be used to send a random access request; then in the random access request response, the sequence number of the resource is indicated in the payload header, and the payload corresponding to the payload header with the indicated sequence number m is the response information of the random access request on the mth resource; wherein, the configuration can be indicated in the signaling used to trigger the random access process.

[0166] Optionally, each payload serving as random access request response information indicates at least one of the following information:

[0167] Information about the random access request to which the response corresponds, such as the resources used by the random access request (which can be indicated by a sequence number); the UE ID indicated in the random access request. This information can be used to distinguish which random access request the response corresponds to;

[0168] The resource information of the random access information corresponding to the response, such as the resources used by the random access information; the type of data information included in the random access information, such as what information is required for inventory.

[0169] Optionally, indicating in the payload of the random access request response information the resources used by the corresponding random access information further includes at least one of the following methods:

[0170] The UE is configured with K resources for random access information, and the sequence number of the resource is indicated in the payload;

[0171] The time domain position of the resources used by the random access information is indicated in the payload, including at least one of its time domain starting position and time domain length, wherein the time domain starting position can be indicated by an offset from a reference point. The reference point can be the transmission time point of the random access request response, and further, can be the starting position or ending position used for the actual transmission of the random access request response, or the starting position or ending position of the resources configured for the random access request response (which can be a superset of the actual transmission used for the random access request response), or the starting position or ending position of the resources used by the random access request; it can also be a preset and / or (pre) configured time point, such as a reference time point configured in the signaling used to trigger the random access process. Optionally, this method is used when the system configures or uses TDM-based random access;

[0172] Indicating in the payload the frequency domain location of the resource used for random access information, including the frequency domain offset between the resource and a reference frequency point, where the reference frequency point includes at least one of the following: a preset and / or (pre)configured frequency point, a center frequency point used for a downlink channel, and a center frequency point used for uplink channel transmission; optionally, this method is used when FDM-based random access is configured or used in the system;

[0173] The payload indicates the coding method for the resources used for random access information, including coding methods such as FM0, Miller, Manchester, and PIE, and further includes the transmission waveform of the Miller code, such as at least one of Miller2, Miller4, and Miller8. Optionally, this method is used when the system is configured or using CDM-based random access.

[0174] Optionally, the UE sends an uplink signal and / or receives a downlink signal, and the intermediate node or base station sends a downlink signal and / or an uplink signal, and further includes: obtaining configuration information associated with frequency hopping; based on the configuration information, sending an uplink signal and / or receiving a downlink signal, or sending a downlink signal and / or an uplink signal in a frequency hopping manner.

[0175] Optionally, the configuration information associated with frequency hopping may be at least one of preset, preconfigured, configured by the base station and / or intermediate node; may be indicated in a broadcast channel, and / or indicated through at least one of MAC signaling, RRC signaling, DCI, payload header, and payload header.

[0176] Optionally, the configuration information associated with frequency hopping includes at least one of the following: a frequency hopping pattern; a bandwidth used for frequency hopping; a transmission using frequency hopping; and a transmission using the configuration information associated with frequency hopping (for example, there may be multiple sets of configuration information, and the configuration information further indicates which transmissions use one or more sets of information). Optionally, the configuration information associated with frequency hopping further includes information corresponding to uplink transmission and / or downlink transmission, which may be configured separately.

[0177] Furthermore, the information about the bandwidth used for frequency hopping includes at least one of the following: bandwidth size, frequency domain starting position, frequency domain ending position, time domain starting time point for starting to use the bandwidth, and time domain ending time point for ending to use the bandwidth. Furthermore, the bandwidth used for frequency hopping may be determined based on the UE's receiving bandwidth.

[0178] In a specific example, the base station indicates the frequency hopping-related configuration information to the UE through a broadcast channel, including several frequency hopping patterns and the bandwidth used for frequency hopping; accordingly, the UE obtains the frequency hopping-related configuration information by receiving the broadcast channel. When the base station sends a downlink transmission, the base station dynamically indicates in the payload header of the downlink transmission whether the downlink transmission is sent by the base station in a frequency hopping manner. The UE can determine whether the downlink transmission is sent by the base station in a frequency hopping manner based on the indication of the received payload header. Optionally, the payload header is not sent in a frequency hopping manner, and the remaining information in the downlink transmission is sent in a frequency hopping manner, so that the UE receives the payload header at a fixed frequency point and receives the remaining information in the downlink transmission according to the indication in the payload header.

[0179] In another specific example, the base station indicates frequency hopping configuration information to the UE via a broadcast channel. When the base station schedules the UE's uplink transmission, the base station dynamically indicates in the scheduling signaling whether the uplink transmission should be sent by the UE in a frequency hopping manner. Accordingly, the UE obtains the frequency hopping configuration information by receiving the broadcast channel and, when sending an uplink transmission, determines whether to send it in a frequency hopping manner based on its scheduling information.

[0180] In another specific example, the base station indicates the frequency hopping-related configuration information to the intermediate node through a broadcast channel. When the base station schedules the UE's uplink transmission based on backscattering, the base station will also schedule the intermediate node to send a carrier signal CW for the UE to perform backscattering, and dynamically indicate in the scheduling signaling sent to the intermediate node whether the CW is sent by the intermediate node in a frequency hopping manner. Accordingly, the intermediate node obtains the frequency hopping-related configuration information by receiving the broadcast channel; and when sending the CW, it determines whether to send it in a frequency hopping manner based on its scheduling information. When the CW is sent in a frequency hopping manner, the UE can no longer perform frequency hopping operations and directly perform backscattering on the frequency hopping CW. The generated uplink transmission is still sent in a frequency hopping manner.

[0181] To improve the reliability of physical layer transmission, a cyclic redundancy check (CRC) may be attached to the data bits as a check method for the physical layer to detect whether the decoded data bits are erroneous.

[0182] Optionally, the signal structure further includes at least one CRC, and the signal / channel / information / signal structure corresponding to the CRC includes at least one of the following: control information, data, a payload header, at least one payload header, all payload headers, a payload header and all, or at least one payload header, at least one payload, all payloads, a payload header, all payload headers, and all payloads. Furthermore, the CRC includes at least one of the above items in the signal structure, and / or at least one of the above items in the signal structure before or after a midamble, such as the entire payload after the midamble, and further such as the payload header, all payload headers, and all payloads before the midamble.

[0183] Among them, the infix includes at least one of the following: a synchronization signal sent in the middle of the payload header, a synchronization signal sent in the middle of the payload, a synchronization signal sent between two payload headers, a synchronization signal sent between two payloads, a synchronization signal sent between the payload header and the payload, and a synchronization signal sent at a non-starting or ending position in the signal structure.

[0184] Optionally, the CRC included in the signal structure may correspond to one or more lengths, may correspond to one or more generating polynomials, that is, correspond to one or more methods of generating CRC; when corresponding to multiple, which length / polynomial / generation method to use may be determined based on the signal / channel / information / signal structure corresponding to the CRC, and / or determined according to the channel type corresponding to the signal structure (for example, an uplink or downlink channel, a control or data channel), and / or determined according to the length of the signal structure or the length of the signal / channel / information / signal structure corresponding to the CRC (for example, whether the number of bits of the information corresponding to the CRC exceeds a threshold corresponding to different CRC lengths / polynomials / generation methods), and / or determined according to configuration / preset information, and / or determined according to information indicated in at least one of the control information, the payload header, and the payload header.

[0185] In an exemplary embodiment, a signal structure does not contain an infix. This signal structure includes a CRC corresponding to the payload header, all payload headers, and all payloads, and the generator polynomial of this CRC is a first polynomial. Another signal structure does contain an infix. This signal structure includes a CRC corresponding to the payload header, all payload headers, and all payloads before the infix, and a CRC corresponding to the entire payload after the infix. The generator polynomials of these two CRCs are a second polynomial. In this example, the CRC generator polynomial is determined based on whether an infix is present and the relationship between the signal / channel / information / signal structure corresponding to the CRC and the infix.

[0186] In various embodiments of the present disclosure, a synchronization signal can be used to acquire synchronization and perform calibration. The synchronization signal can also be replaced by a signal used for channel measurement. The synchronization signal or the signal used for channel measurement can be a signal with a preset specific sequence or waveform, which is used to enable a receiving node to receive it and acquire / calibrate synchronization or measure channel status based on the difference between the received signal and a preset signal.

[0187] In various embodiments of the present disclosure, control information may include a payload header, and / or at least one payload header, or all payload headers; it may also include at least one payload corresponding to the control information, and further include a payload corresponding to a physical layer control channel or signal, and / or a payload corresponding to a higher-layer control channel or signal. Data may include at least one payload, or all payloads; it may also include a payload corresponding to a data channel, and / or a payload corresponding to a higher-layer control channel or signal, but not include a payload corresponding to a physical layer control channel or signal.

[0188] In various embodiments of the present disclosure, the payload in the signal structure includes a payload corresponding to a physical layer control channel or signal, and the physical layer control channel or signal includes at least one of the following: a signal / channel for indicating control information for downlink transmission of AIoT; a signal / channel for indicating control information for uplink transmission of AIoT; and a scheduling request (SR).

[0189] In various embodiments of the present disclosure, the broadcast channel may be replaced by a broadcast signal, and the broadcast channel and / or broadcast signal may be transmitted via a data channel. For example, in a system, unicast data sent to a single terminal, multicast data sent to multiple terminals, and broadcast data sent to all terminals may all be sent on the same physical layer channel, referred to as a data channel. Furthermore, the type of information indicated in the data channel may be distinguished as unicast, multicast, or broadcast through additional methods such as indications in control information, indications of the receiving terminal's identity, and sequence indications.
