Description

METHOD AND APPARATUS FOR TRANSMITTING RANDOM ACCESS SIGNAL FIELD OF INVENTION This application relates to the field of communications and, more specifically, to a method and apparatus for transmitting a random access signal. BACKGROUND OF THE INVENTION In a conventional solution, a terminal can access a network device using either a two-step or a four-step random access method. The random access signal used for this access can be generated using a random access formula. This signal can be a "1" in the four-step random access method, or an "A" in the two-step random access method. Furthermore, the random access formula includes a variable subcarrier count parameter, which defines a frequency domain interval (also known as a guard interval) between the random access signal and the data signal. Therefore, to ensure the accuracy of the generated random access signal and improve random access efficiency, a method for determining the subcarrier count parameter is urgently needed. BRIEF DESCRIPTION OF THE INVENTION This application provides a method and apparatus for transmitting a random access signal, to obtain a precise subcarrier quantity parameter, thereby improving random access efficiency. According to the first aspect, a method for transmitting a random access signal is provided. The method includes: receiving configuration information, where the configuration information is used to indicate a random access preamble length, a random access signal subcarrier spacing, and a data subcarrier spacing;determine a subcarrier quantity parameter based on at least one of the random access preamble length, the random access signal subcarrier spacing, and the data subcarrier spacing, wherein the subcarrier quantity parameter includes a first subcarrier quantity used to indicate a frequency resource start location of a random access preamble and a frequency resource start location of a random access physical channel, and / or a second subcarrier quantity used to indicate a frequency resource end location of the random access preamble and a frequency resource end location of the random access physical channel; generate a random access signal based on the subcarrier quantity parameter; and send the random access signal. A terminal receives the configuration information and determines the number of subcarriers parameter with reference to at least one of the random access preamble length, the random access signal subcarrier spacing, and the data subcarrier spacing, as indicated by the configuration information. In this way, the terminal can generate an accurate random access signal, thereby improving random access efficiency. In some possible implementations, a random access signal subcarrier separation value is any of 120 kHz, 240 kHz, 480 kHz, 960 kHz, 1920 kHz, and 3840 kHz. The modalities of this request can be applied to a scenario below 52.6 GHz. The subcarrier spacing can alternatively be greater than or equal to 240 kHz; that is, this request can also be applied to a scenario greater than or equal to 52.6 GHz, thus extending the application range of random access. In some possible implementations, a value for the data subcarrier separation is any of 240 kHz, 480 kHz, 960 kHz, 1920 kHz, and 3840 kHz. This request can be applied to a scenario greater than or equal to 52.6 GHz, to implement random access, thereby extending a random access application range. In some possible implementations, a value for the number of subcarriers parameter is any of -15, -7, -5, -3, -1, 0, 1, 2, 3, 19, 23, 83, and 107. The different values ​​of the subcarrier quantity parameter can flexibly adjust the first and second subcarrier quantity, i.e., in modalities of this application, the guard interval sizes can be flexibly adjusted to implement applicability to different scenarios. In some possible implementations, determining a subcarrier count parameter based on at least one of the random access preamble length, random access signal subcarrier spacing, and data subcarrier spacing includes: determining a total subcarrier count frequency domain width based on the random access preamble length, random access signal subcarrier spacing, and data subcarrier spacing; and determining the subcarrier count parameter based on the total subcarrier count frequency domain width, random access signal subcarrier spacing, and data subcarrier spacing. The terminal can first determine the total number of subcarriers in the frequency domain and then further determine the number of subcarriers parameter; that is, it can indirectly obtain the number of subcarriers parameter. Therefore, the modalities of this application provide an implementation for determining a number of subcarriers parameter, to help generate an accurate random access signal and also to help improve random access efficiency. In some possible implementations, determining a subcarrier count parameter based on at least one of the random access preamble length, random access signal subcarrier separation, and data subcarrier separation includes: determining the subcarrier count parameter in the second target parameter based on the random access signal subcarrier separation and data subcarrier separation in the first target parameter. The terminal can determine the number of subcarriers parameter with reference to the random access signal subcarrier spacing and the data subcarrier spacing. For example, the terminal can store a mapping relationship between the random access signal subcarrier spacing and the data subcarrier spacing with the number of subcarriers parameter. Therefore, the modalities in this application provide another implementation for determining a number of subcarriers parameter, to help generate an accurate random access signal and further improve random access efficiency. In some possible implementations, the first number of subcarriers and the second number of subcarriers are equal.

Land Mobile Network (PLMN) or similar. This is not limited to the types of applications in this application. A network device in the modalities of this application may be a device configured to communicate with a terminal. The network device may be a base transceiver station (BTS) in the Global System for Mobile Communications (GSM) or code division multiple access (CDMA) system, or it may be a NodeB (NB) in the wideband code division multiple access (WCDMA) system, or it may be an evolved NodeB (eNB or eNodeB) in the LTE system, or it may be a radio controller in a cloud radio access network (GRAN) scenario, or the network device may be a relay station, an access point, a vehicle-mounted device, a handheld device, a network device in a future 5G network,A network device in a future evolved PLMN network, or an antenna panel or group of antenna panels (including a plurality of antenna panels) of a base station in a 5G system, or a network node constituting a 5G base station (gNB) or a transmission point, for example, a baseband unit (BBU) or a distributed unit (DU). This is not limited in the modalities of this application. In some implementations, the gNB may include a centralized unit (CU) and a domain unit (DU). The gNB may also include an active antenna unit (AAU). The CU implements some gNB functions, and the DU implements some gNB functions. For example, the CU is responsible for processing a non-real-time protocol and service, and for implementing radio resource control (RRC) and packet data convergence protocol (PDCP) layer functions. The DU is responsible for processing a physical layer protocol and a real-time service, and for implementing radio link control (RLC) layer functions, media access control (MAC) layer functions, and a physical (PHY) layer function. The AAU implements some physical layer processing functions, radio frequency processing functions, and a function related to an active antenna.Information in the RRC layer is eventually converted into information in the PHY layer, or converted from information in the PHY layer. Therefore, in the architecture, upper-layer signaling, such as RRC layer signaling, can also be considered as sent by the DU or by both the DU and the AAU. A network device can be understood as a device that includes one or more CU nodes, a DU node, and an AAU node. Furthermore, a CU can be classified as a network device in a radio access network (RAN), or a network device in a core network (CN). This is not the scope of this application. iviA / a / zuzz / ui ¿ooj In some versions of this application, the terminal or network device includes a hardware layer, an operating system layer that runs on top of the hardware layer, and an application layer that runs on top of the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory). The operating system can be any one or more computer operating systems that implement service processing through a process, for example, a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system, or a Windows operating system. The application layer includes applications such as a web browser, an address book, word processing software, and instant messaging software.Furthermore, a specific structure for the execution body of a method provided in the modalities of this request is not particularly restricted, provided that a program that records the code of the method provided in the modalities of this request can be executed to perform the communication in accordance with the method provided in the modalities of this request. For example, the method provided in the modalities of this request can be implemented by the terminal or network device, or by a functional module that can invoke and execute the program on the terminal or network device. Furthermore, the aspects or features of this application may be implemented as a method, apparatus, or product using standard engineering and / or programming technologies. The term "product" used in this application covers a computer program that can be accessed from any computer-readable component, carrier, or medium. For example, a computer-readable medium may include, but is not limited to: a magnetic storage component (e.g., a hard disk, floppy disk, or magnetic tape), an optical disc (e.g., a compact disc (CD) or a digital versatile disc (DVD)), a smart card, and a flash memory component (e.g., an erasable programmable read-only memory (EPROM), a card, a USB flash drive, or a USB drive).In addition, various storage media described in this specification may indicate one or more machine-readable devices and / or other media configured to store information. The term machine-readable media may include, but is not limited to, a wireless channel and various other media that can store, contain, and / or carry instructions and / or data. The following describes in detail the terms in this application. 1. Random access preamble: The random access preamble can be actual content sent by a terminal in MA / a / ZUZZ / UI ZDOJ is a physical random access channel. The random access preamble is a ZC sequence. The ZC sequence preamble can be generated using different cyclic changes. Different ZC sequence preambles can be used for different users. In LTE and 5G NR systems, a cell typically has 64 different random access preambles. 2. Antenna port: The antenna port is a logical concept, and there is no direct correspondence between an antenna port and a physical antenna. The antenna port is generally associated with a reference signal and can be specifically understood as a transceiver interface on a channel through which the reference signal passes. At low frequencies, an antenna port may correspond to one or more antenna array elements, and these array elements collectively transmit a reference signal. A receiving end may consider the received reference signals as a whole, without distinguishing the array elements from which the reference signals are transmitted. For a high-frequency system, a plurality of antenna ports may correspond to a beam. Similarly, a receiving end may only need to consider the beam as an interface, without distinguishing each array element. 3. Licensed resource: A licensed resource is generally a resource that can provide high-quality communications, typically a time-frequency resource whose use requires approval from a national or local wireless committee. Different systems, such as an LTE system and a Wi-Fi system, or systems from different operators, cannot share a licensed time-frequency resource. 4. Unlicensed resource: An unlicensed resource can offload traffic, allowing a licensed resource to achieve good coverage and capacity, thereby improving the user experience. Specifically, the unlicensed resource can be shared by multiple communication devices. Sharing the unlicensed resource means that, for the use of a particular spectrum, limitations are imposed only on indicators such as transmission power and out-of-band emissions, to ensure that multiple devices sharing the band meet a basic coexistence requirement. An operator can implement network traffic offloading using an unlicensed resource, but must comply with the regulatory requirements of different regions and different spectrums within that unlicensed resource.These requirements are generally set to protect a public system such as radar and to ensure that a plurality of systems coexist equitably and cause as little negative impact on each other as possible, and include a transmission power limit, an out-of-band emission specification, and indoor and outdoor use restrictions. IVIA / a / ZUZZ / UI ¿OOJ In addition, some regions have further coexistence policies. For example, communication devices may use a time-frequency resource in a containment or listening manner, such as a listen-before-talk (LBT) mode. For example, but without limitation, in embodiments of the present invention, the unlicensed resource (specifically, an unlicensed resource) may include a band near 5 GHz, a band near 2.4 GHz, a band near 3.5 GHz, and a band near 6 GHz. Furthermore, for example, but without limitation, in embodiments of the present invention, a communications system may utilize, for example, a licensed-assisted access (LAA) technology, a dual connectivity (DO) technology, or a standalone technology. LAA includes using a carrier aggregation (CA) configuration and structure in the existing LTE system, and based on the configuration of a carrier (licensed carrier) in an operator's licensed band for communication, configuring carriers (unlicensed carriers) in a plurality of unlicensed resources and performing communication by using an unlicensed carrier with the assistance of the licensed carrier.In other words, an LTE device can use, in a dual-carrier (DC) manner, the licensed carrier as the primary component carrier (PCC) or primary service cell (PCell), and the unlicensed carrier as the secondary component carrier (SCC) or secondary service cell (SCell). Dual-carrier (DC) connectivity technology includes co-using a licensed and an unlicensed carrier in a non-DC manner, or it may further include co-using multiple unlicensed carriers in a non-CA manner. Alternatively, the LTE device can be deployed directly on an unlicensed carrier through a standalone deployment. It can be understood that the modalities of this request can be applied to a licensed resource and can also be applied to an unlicensed resource. 5. Bandwidth: Bandwidth can be understood as continuous or discontinuous resources in the frequency domain. For example, bandwidth can be a cell, a carrier, or a bandwidth part (BWP). A cell can be a service cell of a terminal. The service cell is described at a high layer from a resource management, mobility management, or service unit perspective. A coverage area of ​​each network device can be divided into one or more service cells, and a service cell can be considered to include a specific frequency domain resource; that is, a service cell can include one or more carriers. The concept of a carrier is described from IVIA / a / 2U22 / Ul 2000 provides a perspective on signal generation at a physical layer. A carrier is defined by one or more frequencies, corresponds to continuous or discontinuous spectra, and is configured to carry communication data between a network device and a terminal. A downlink carrier can be configured for downlink transmission, and an uplink carrier can be configured for uplink transmission. Furthermore, a carrier can include one or more bandwidth segments. It should be noted that if a cell includes a carrier, the carrier can be considered an independent cell without regard to its physical location. That is, the carrier can be replaced by the cell in an equivalent manner. It should be understood that BWP can be referred to as a carrier bandwidth part, a subband bandwidth, a narrowband bandwidth, or another name. For ease of description, the following modalities use BWP as an example, but this is not the only term used in this application. It should be noted that with the continuous development of technologies, the terms in the modalities of this application may change, but all of them fall within the scope of protection of this application. Figure 1 is a schematic diagram of a communications system according to this application. The communications system in Figure 1 may include at least one terminal (for example, Terminal 10, Terminal 20, Terminal 30, Terminal 40, Terminal 50, and Terminal 60) and one network device 70. Network device 70 is configured to provide communications service to the terminal and access a core network. The terminal can access a network by searching for a synchronization signal, broadcast signal, or similar signal sent by network device 70 to communicate with the network. Terminals 10, 20, 30, 40, and 60 in Figure 1 can perform uplink and downlink transmission with network device 70.For example, network device 70 can send downlink signals to terminal 10, terminal 20, terminal 30, terminal 40, and terminal 60, and can receive uplink signals sent by terminal 10, terminal 20, terminal 30, terminal 40, and terminal 60. Furthermore, terminals 40, 50, and 60 can also be considered a communications system. Terminal 60 can send downlink signals to terminals 40 and 50, or it can receive uplink signals sent by terminals 40 and 50. It should be noted that the modalities of this application can be applied to a communications system that includes one or more network devices, and can also be applied to ML / a / ZUZZ / U 1 ZOOJ a communications system that includes one or more terminals. This is not limited in this application. It should be understood that the communications system may include one or more network devices. A network device may send data or control signaling to one or more terminals. A plurality of network devices may simultaneously send data or control signaling to one or more terminals. Figure 2 is a schematic diagram of a four-step random access process in a conventional solution. After selecting a suitable cell to complete the camping process, a terminal can initiate random access. As shown in Figure 2, the UE sends message 1 (message 1, msg 1) to a network device. Message 1 is a random access preamble. After detecting the random access preamble, the network device returns a response message, message 2 (message 2), to the UE. Message 2 includes an uplink resource allocated by the network device to the UE. After receiving message 2, the UE sends message 3 on the uplink resource indicated by message 2. If the network device can successfully decode message 3 (message 3), it returns message 4 (message 4) to the UE.Message 4 is used to notify the UE of a successful contention. After the four previous steps, a random access procedure is successful. Figure 3 is a schematic diagram of a two-step random access process in a conventional solution. In the two-step random access process, the UE adds both a random access preamble and data to message A. The data portion is used for contention resolution, for example, a radio resource control (RRC) message. If there is no conflict between the UEs, a network device returns message B to the UE after successfully decoding message A. Message B includes both a response to the random access preamble and a response to the data. The response to the random access preamble is a random access response (RAR). The response to the data is typically an RRC message. The two responses can be sent simultaneously or sequentially. The UE can decode the two responses independently.After receiving message B, the UE learns that random access is successful. It can be understood that if there is a conflict between UEs, the network device may not successfully decode the data in message A. In this case, the network device does not send message B to the UE. After sending message A, the UE waits for a window of time. If the UE does not receive message B, it considers random access to have failed. In a conventional solution, a terminal can generate, based on a formula of IVIA / a / ZUZZ / UI ZOOJ random access, a random access signal used for random access. For example, the random access formula is as follows: c(P,A) / A _ (p,RA} j2n{k+Kk}+k)AfM^ ' ¿¿k=oUkwhere & ~ , p is an antenna port index, is an index of a data subcarrier separation,Lra is a random access preamble length, t kes is a value k of a random access preamble, 0 is a time domain location of the random access signal, is a separation of random access signal subcarriers, K is a multiple of the data subcarrier separation and the random access signal subcarrier separation, ki is used to indicate a location of an RB occupied by the random access signal (or a physical random access channel) (the RB is determined based on the random access signal subcarrier separation), is a subcarrier quantity parameter, and the subcarrier quantity parameter is used to indicate a guard interval between the random access signal and a data signal. Subcarrier spacing can be understood as the width of a subcarrier. For example, data subcarrier spacing is the width of a data subcarrier, or the width of a subcarrier spacing within a portion of the initial uplink access bandwidth, or the width of a subcarrier spacing within a portion of the initial downlink access bandwidth, or the width of a subcarrier spacing corresponding to a portion of the uplink bandwidth where the physical random access channel is located. Random access signal subcarrier spacing is the width of a random access signal subcarrier. Random access signal subcarrier spacing is also known as subcarrier spacing for random access preambles.In the following mode, data subcarrier spacing is described by using subcarrier spacing of a physical uplink shared channel (PUSCH) as an example, and random access signal subcarrier spacing is described by using subcarrier spacing of a physical random access channel (PRACH) as an example. Generally, a ki granularity is a number of subcarriers in a RB. For example, if the number of subcarriers in an RB is 12, the ki granularity is 12. That is, a ki value is a multiple of 12. It can also be understood that the The granularity of ki can be an integer number of subcarriers or a fractional number of RB. For example, the granularity of ki is 1 / 2 of the number of subcarriers in an RB. For example, if the number of subcarriers in an RB is 12, the granularity of ki is 6. That is, a value of ki is a multiple of ±6. In a conventional communications system, the length of a random access preamble is generally not a number of subcarriers corresponding to an integer number of RB, whereas a physical random access channel is generally a number of subcarriers corresponding to an integer number of RB. Therefore, when the random access preamble is modulated onto a frequency location of the random access channel, some subcarriers within the bandwidth occupied by the random access channel are unallocated. These unallocated subcarriers can function as a guard interval, protecting a signal carried on the random access channel or another nearby signal that is allocated to a location of an integer number of RB, thus preventing interference caused by non-ideality (e.g., frequency offset) in a real-world system from reducing system performance.It can be used to adjust a guard interval location, i.e., adjust a subcarrier location to which the random access preamble is mapped in the PRACH (or a subcarrier location occupied by a random access signal corresponding to the random access preamble). It can also be understood that the random access preamble length and the random access signal subcarrier spacing determine the size of the frequency resource actually used by the random access signal. The data subcarrier spacing and the number of random access bits (RB) occupied by the random access signal determine the size of the frequency resource occupied by the random access signal. Clearly, the size of the frequency resource occupied by the random access signal is greater than or equal to the size of the frequency resource actually used by the random access signal. As shown in Figure 4, the guard interval of the random access signal can include two guard intervals: a guard interval 1 and a guard interval 2. The respective sizes of the two guard intervals shown in Figure 4 can be adjusted. The terminal may have a parameter in formula (1) other than the number of subcarriers parameter (^). Therefore, how this is determined needs to be resolved urgently. A frequency domain direction can be understood as running from left to right. WUUa / 4U44 / Ul 4000 shown in Figure 4 is an increasing frequency domain direction. Therefore, if the left-to-right frequency domain direction is a decreasing frequency domain direction, guard interval 1 and guard interval 2 can be shown in Figure 5. Figure 6 is a schematic flowchart of a method for transmitting a random access signal according to a modality of this request. It should be understood that the mode shown in Figure 6 can be executed by a terminal, or it can be a chip in the terminal. This is not limited to this application. For ease of description, the following uses the terminal as an example. However, this application is not limited to it. 601. The terminal receives configuration information, wherein the configuration information is used to indicate a random access preamble length, a random access signal subcarrier spacing, and a data subcarrier spacing. Specifically, the terminal can receive configuration information from a network device. Conversely, the network device can send configuration information to the terminal. This configuration information can specify at least the random access preamble length, the random access signal subcarrier spacing, and the data subcarrier spacing. It can be understood that the configuration information can directly indicate the random access preamble length. For example, the configuration information includes the random access preamble length. Alternatively, the configuration information can indirectly indicate the random access preamble length. For example, the configuration information includes a random access physical channel configuration index. That is, the terminal can obtain a random access preamble format based on the random access physical channel configuration index and, correspondingly, obtain the random access preamble length. Similarly, the configuration information can also directly or indirectly indicate the random access signal subcarrier spacing or the data subcarrier spacing.For example, the configuration information may also include subcarrier spacing for random access preambles and / or subcarrier spacing for a portion of the initial uplink bandwidth. Subcarrier spacing for the initial uplink bandwidth portion is data subcarrier spacing. Optionally, the random access preamble length can be any of 139, 839, 571, or 1151. That is, this request can expand an application range of WUUa / 4U44 / Ul 4000 random access. Optionally, the separation of the random access signal subcarriers can be any of 1.25 KHz, 5 KHz, 15 KHz, 30 KHz, 60 KHz, 120 KHz, 240 KHz, 480 KHz, 960 KHz, 1920 KHz and 3840 KHz. Optionally, the spacing of data subcarriers can also be any of 1.25 KHz, 5 KHz, 15 KHz, 30 KHz, 60 KHz, 120 KHz, 240 KHz, 480 KHz, 960 KHz, 1920 KHz and 3840 KHz. A random access signal subcarrier spacing of less than 240 kHz (e.g., 1.25 kHz, 5 kHz, 15 kHz, 30 kHz, 60 kHz, or 120 kHz) can be understood to correspond to a carrier frequency band scenario below 52.6 GHz. A random access signal subcarrier spacing greater than or equal to 240 kHz corresponds to a carrier frequency band scenario greater than or equal to 52.6 GHz. Optionally, a data subcarrier spacing of less than 240 kHz (e.g., 15 kHz, 30 kHz, 60 kHz, or 120 kHz) corresponds to a carrier frequency band scenario below 52.6 GHz. A data subcarrier spacing greater than or equal to 240 kHz corresponds to a carrier frequency band scenario greater than or equal to 52.6 GHz. 602. The terminal determines a subcarrier count parameter based on at least one of the random access preamble length, the random access signal subcarrier spacing, and the data subcarrier spacing, wherein the subcarrier count parameter includes a first subcarrier count used to indicate a frequency resource start location of a random access preamble and a frequency resource start location of a random access physical channel, and / or a second subcarrier count used to indicate a frequency resource end location of the random access preamble and a frequency resource end location of the random access physical channel. Specifically, the terminal can determine the number of subcarriers by referencing at least one of the random access preamble lengths, the random access signal subcarrier spacing, and the data subcarrier spacing. This helps the terminal generate an accurate random access signal, thereby improving random access efficiency. For example, the terminal can store a mapping relationship of at least one of the random access preamble length, the random access signal subcarrier spacing, and the data subcarrier spacing, with the number of subcarriers parameter. The mapping relationship can be implemented using a formula or a table. This is not limited in this application. IVIA / a / ZUZZ / UI ZOOJ It can be understood that the start location of the random access preamble frequency resource is a starting location on a subcarrier corresponding to the physical random access channel, from which the random access preamble is mapped, and the end location of the random access preamble frequency resource is a final location on the subcarrier corresponding to the physical random access channel, to which the random access preamble is mapped. The number of subcarriers parameter includes the first number of subcarriers used to indicate the start location of the random access preamble frequency resource and the start location of the random access physical channel frequency resource, that is, the guard interval 1 shown in Figure 4 or Figure 5.The subcarrier count parameter may also include the second subcarrier count used to indicate the frequency resource end location of the random access preamble and the frequency resource end location of the random access physical channel, i.e., guard interval 2 shown in Figure 4 or Figure 5. It should be noted that the number of subcarriers parameter can include only the first number of subcarriers, or only the second number of subcarriers, or both. When the number of subcarriers parameter includes only the first or second number of subcarriers, the terminal can derive the other number of subcarriers by reference to a total number of subcarriers (which can also be referred to as a total number of subcarriers width in the following mode). For example, if the number of subcarriers includes the first number of subcarriers, the terminal can obtain the second number of subcarriers by subtracting the first number of subcarriers from the total number of subcarriers. It can also be understood that the frequency resource can also be referred to as a frequency domain resource, which are not distinguished in the following modality. In one mode, step 602 may be specifically as follows: The terminal first determines a total number of subcarriers frequency domain width based on the random access preamble length, random access signal subcarrier spacing, and data subcarrier spacing in the configuration information, and then determines the number of subcarriers parameter based on the total number of subcarriers frequency domain width, random access signal subcarrier spacing, and data subcarrier spacing. Specifically, the total number of subcarriers frequency domain width can be the total frequency domain width occupied by guard interval 1 and guard interval 2 shown in Figure 4. That is, the terminal can determine WUUa / 4U44 / Ul 4000 first determines the total number of subcarriers in the frequency domain, and then further determines the number of subcarriers parameter. In other words, the terminal can indirectly obtain the number of subcarriers parameter. Optionally, the terminal may determine a frequency domain width of total number of subcarriers based on the random access preamble length, the random access signal subcarrier separation, and the data subcarrier separation, which can be specifically as follows: GP = NfB^f^N')-LRA^fRA^ where GP represents the frequency domain width of the total number of subcarriers, Y represents the data subcarrier spacing, RA represents the random access signal subcarrier spacing, RB represents the total number of frequency domain resource blocks allocated to a random access signal, N represents the number of subcarriers in an RB, and R represents the random access preamble length. * represents multiplication, and can also be denoted as x. It can be understood that, in NR, the number of subcarriers in an RB can be 12. In the following modality, N=12 is used as an example for description. However, this request is not limited to it. NRA It can be understood that seRB can be known, or can be determined by using the following formula (3), which is not limited in this application: N^ = ceil{LRA^fRA / ^f^ / V))(3) L NradondeRA represents the random access preamble length,RB represents the total number of frequency domain resource blocks allocated to the random access signal, N represents the number of subcarriers in an RB, represents the data subcarrier separation, represents the random access signal subcarrier separation, and ceil represents rounding up. For example, if N=12, Lra=139, =240 KHz, and =60 KHz, =ceil(139*240 / (60*12))=47, that is, a random access signal occupies 47 RB in the frequency domain. Therefore, GP=47*(60 * 12)-139*240=480 KHz can be obtained based on formula (2). ooj It can also be understood that the terminal can alternatively directly determine the number of subcarriers parameter based on the random access preamble length, the random access signal subcarrier spacing, and the data subcarrier spacing, for example, by using the following formula (4), i.e., the Nraterminal does not need to learn the intermediate parameter RB: GP = ceil^ * ^fRA / (Δ / * N)) * (Δ / * N) - * ^fRA (4)where GP represents the frequency domain width of the total number of subcarriers, L represents the random access preamble length, RB represents the total number of frequency domain resource blocks allocated to the random access signal, N represents the number of subcarriers in an RB, represents the data subcarrier separation, represents the random access signal subcarrier separation, and ceil represents rounding up. Optionally, the first number of subcarriers and the second number of subcarriers are equal. Specifically, guard interval 1 and guard interval 2 can be equal, so that the terminal can implement the same impact on data demodulation at both ends of the random access signal, thereby reducing the complexity of the terminal. Optionally, when the first number of subcarriers and the second number of subcarriers are equal, the frequency domain width of the total number of subcarriers, the random access signal subcarrier spacing, the data subcarrier spacing, and the number of subcarriers parameter satisfy the following relationship: 2 2+0.5ΔLα (5) where GP represents the frequency domain width of the total number of subcarriers, represents the separation of data subcarriers, represents the separation of random access signal subcarriers and represents the number of subcarriers parameter. Specifically, as shown in Figure 7, guard interval 1 and guard interval 2 are the same means that guard interval 1 or guard interval 2 is GP / 2, and GP / 2 satisfies the following relationship: G?|2=GPI2 = ^fRAk-^fRAl2+^fl2(6) In this way, formula (5) can be derived from formula (6). It can be understood that any transformation made to formula (5) is within the scope of protection of this application. Optionally, the terminal can store the following table (Table 1).

Specifically, the terminal can determine the number of subcarriers parameter with reference to the random access signal subcarrier spacing and the data subcarrier spacing. For example, the terminal can store a mapping relationship between the random access signal subcarrier spacing and the data subcarrier spacing with the number of subcarriers parameter. The mapping relationship can be implemented using a formula or a table. This is not limited in this application. Optionally, the second number of subcarriers and the total number of subcarriers frequency domain width can be equal, and the first number of subcarriers is zero. Optionally, when the first number of subcarriers is 0, i.e., when the guard interval 1 shown in Figure 4 is 0, the random access signal subcarrier spacing, the data subcarrier spacing, and the number of subcarriers parameter satisfy the following relationship: Δ / u (9) where represents the separation of data subcarriers, ^RA represents the separation of random access signal subcarriers and represents the number of subcarriers parameter. Specifically, the terminal determines a value based on formula(9), that is, the terminal moves a location of a subcarrier to which the random access preamble is mapped towards a center of the random access channel, thus helping to reduce interference with another data channel. Optionally, the random access signal subcarrier separation, the data subcarrier separation, and the number of subcarriers parameter can alternatively satisfy the following relationship: ινΐΛ / a / zuzz / ui ¿ooj Specifically, the terminal determines a value based on formula (10), i.e., the terminal moves a location of a subcarrier to which the random access preamble is mapped toward a center of the random access channel, thereby helping to reduce interference with another data channel. Specifically, when ^=139, the correspondences for RA=139 can be shown in the following Table 12 or Table 13, the correspondences for ^=571 can be shown in the following Table 14 or Table 15, and the correspondences between ^KA=\ 151 can be shown in the following Table 16 or Table 17.

The terminal generates a random access signal based on the subcarrier count parameter. Specifically, the terminal can generate the random access signal based on the number of subcarriers parameter and a random access formula. The random access formula can be shown in formula (1). It can be understood that any transformation can be performed on formula (1) and is within the scope of protection of this application. Furthermore, the random access formula for generating the random access signal via the terminal can be an alternative formula. This is not limited in this application. 604. The terminal sends the random access signal. Specifically, the terminal can send the random access signal to the network device. Correspondingly, the network device can receive the random access signal from the terminal. If the terminal sends the random access signal generated based on formula (1), the terminal can send the random access signal through an antenna port p. Therefore, in this mode of the request, the terminal receives the configuration information and determines the number of subcarriers based on at least one of the random access preamble lengths, the random access signal subcarrier spacing, and the data subcarrier spacing, as specified in the configuration information. This allows the terminal to generate a precise random access signal, thereby improving random access efficiency. The modalities described in this specification can be standalone solutions or can be combined based on intrinsic logic. All of these solutions fall within the scope of protection of this application. It can be understood that, in the preceding method modalities, the methods and operations implemented by the terminal can be implemented alternatively by a component (for example, a chip or a circuit) that can be applied to the terminal, and the methods and operations implemented by the network device can be implemented alternatively by a component (for example, a chip or a circuit) that can be applied to the network device. The foregoing primarily describes the solutions provided in the modalities of this request from the perspective of interaction between network elements. It can be understood that, to implement the above functions, each network element, such as the transmitting end device or the receiving end device, includes a corresponding hardware structure and / or software module to perform each function. A person skilled in the art should be aware that the units, algorithms, and steps in the examples described with reference to the modalities disclosed in this specification can be implemented in a single form of hardware or a combination of computer hardware and software in this request. Whether a function is performed by hardware or hardware driven by computer software depends on a particular application and a design constraint of the technical solutions.A person skilled in the technique can use different methods to implement the functions described for each particular application, but it is not necessary to consider that the implementation goes beyond the scope of this request. In the modalities of this application, function module division can be performed at the transmitting or receiving end device based on the previous method examples. For example, each function module can be obtained through division corresponding to each function, or two or more functions can be integrated into a processing module. The integrated module can be implemented in hardware or as a software functional module. It should be noted that, in the modalities of this application, the division within modules is an example and simply represents the division of logical functions; it may be a different division in the actual implementation. The following provides a description using an example where each function module is obtained through division corresponding to each function. It should be understood that the specific examples in modalities of this request are proposed simply to help a technical expert to better understand the modalities of this request, however they are not intended to limit the scope of the modalities of this request. It should be understood that the sequence numbers of the processes mentioned above do not signify execution sequences in the modalities of this request. The execution sequences of the processes must be determined based on the functions and internal logic of the processes and should not constitute any limitation on the implementation processes of the modalities of this request. The method provided in the specifications of this application is described in detail above with reference to Figures 4 through 7. The apparatus provided in the specifications of this application is described in detail below with reference to Figures 8 through 15. It should be understood that the description of the apparatus specifications corresponds to the description of the method specifications. Therefore, for content not described in detail, reference is made to the previous method specifications. For the sake of brevity, no further details are described herein. Figure 8 is a schematic block diagram of an 800 device for transmitting a random access signal according to one modality of this request. It should be understood that the device 800 may correspond to each terminal or a chip in the terminal shown in Figure 1, or the terminal or a chip in the terminal in the mode shown in Figure 6, and may have any function of the terminal in the method mode shown in Figure 6. For example, the device 800 includes a transceiver module 810 and a processing module 820. The 810 transceiver module is configured to receive configuration information, where the configuration information is used to indicate a random access preamble length, a random access signal subcarrier spacing, and a data subcarrier spacing. The 820 processing module is configured to determine a subcarrier count parameter based on at least one of the random access preamble length, random access signal subcarrier spacing, and data subcarrier spacing, where the subcarrier count parameter includes a first subcarrier count used to indicate a frequency resource start location of a random access preamble and a frequency resource start location of a random access physical channel, and / or a second subcarrier count used to indicate a frequency resource end location of the random access preamble and a frequency resource end location of the random access physical channel. The 820 processing module is also configured to generate a signal of WUUa / 4U44 / Ul 4000 random access based on the subcarrier count parameter. The 810 transceiver module is also configured to send the random access signal. Optionally, a random access signal subcarrier separation value is any of 120 kHz, 240 kHz, 480 kHz, 960 kHz, 1920 kHz, and 3840 kHz.

Details are not described again here. In this specific implementation, in one mode, the 1100 device may also include an output device and an input device. The output device communicates with the 1110 processor and can display information in a variety of ways. For example, the output device may be a liquid crystal display (LCD), a light-emitting diode (LED) display, a cathode ray tube (CRT) display, or a projector. The input device communicates with the 1110 processor and can receive user input in a variety of ways. For example, the input device may be a mouse, a keyboard, a touchscreen device, or a sensor device. Figure 11 is understood to show only a simplified design of the communications apparatus. In actual application, the apparatus may also include other necessary elements, including but not limited to any number of transceivers, processors, controllers, memories, or similar components. All elements that may implement the network device in this application fall within the scope of protection of this application. In one possible design, the 1100 device can be a chip—for example, a communications chip used in the network device—configured to implement a related function of the 1110 processor within the network device. The chip could be a field-programmable gate array, a special integrated chip, a system chip, a central processing unit, a network processor, a digital signal processing circuit, or a microcontroller, or it could be a programmable controller or another integrated chip.

One form of this request also provides an apparatus. The apparatus can be a network device, or it can be a circuit. The apparatus can be configured to perform an action performed by the network device in the preceding method forms. Optionally, when the device in the modes is a terminal, Figure 12 is a schematic diagram of a simplified terminal structure. For ease of understanding and drawing, a mobile phone is used as an example of the terminal in Figure 12. As shown in Figure 12, the terminal includes a processor, memory, and a circuit. The MA / a / ZUZZ / UI ZOOJ radio frequency device includes an antenna and an input / output device. The processor is primarily configured to process communication protocols and data, control the terminal, execute software programs, process software program data, and similar functions. The memory is primarily configured to store software programs and data. The radio frequency circuitry is primarily configured to convert between a baseband signal and a radio frequency signal and to process the radio frequency signal. The antenna is primarily configured to receive and transmit radio frequency signals in the form of an electromagnetic wave. The input / output device, such as a touchscreen, display, or keyboard, is primarily configured to receive data entered by a user and output data to the user.It should be noted that some types of terminal devices may not have an input / output device. When data needs to be sent, the processor performs baseband processing on the data to be sent and then outputs a baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then transmits a radio frequency signal externally as an electromagnetic wave through the antenna. When data is sent to the terminal, the radio frequency circuit receives a radio frequency signal through the antenna, converts the radio frequency signal back into a baseband signal, and sends the baseband signal to the processor. The processor converts the baseband signal back into data and processes the data. For ease of description, Figure 12 shows only one memory and one processor. An actual terminal product may include one or more processors and one or more memories.Memory can also be referred to as a storage medium, a storage device, or similar terms. Memory can be located independently of the processor or integrated with it. This is not a limitation of this application. In this application, the antenna and radio frequency circuitry, which have a transceiver function, can be considered the terminal's transceiver unit, and the processor, which have a processing function, can be considered the terminal's processing unit. As shown in Figure 12, the terminal includes a transceiver unit 1210 and a processing unit 1220. The transceiver unit can also be referred to as a transceiver, a transceiver apparatus, or similarly. The processing unit can also be referred to as a processor, a processing board, a processing module, a processing apparatus, or similarly.Optionally, a component in the 1210 transceiver unit configured to perform a receive function can be considered a receive unit, and a component in the 1210 transceiver unit configured to perform a send function can be considered a send unit. In other words, the 1210 transceiver unit. MA / a / ZUZZ / UI ZDOJ includes the receiving unit and the sending unit. The receiving unit may sometimes also be referred to as a transceiver, a transceiver circuit, or similar. The receiving unit may sometimes also be referred to as a receiver, a receiving circuit, or similar. The sending unit may sometimes also be referred to as a transmitter, a transmitting circuit, or similar. It should be understood that the 1210 transceiver unit is configured to perform a send operation and a receive operation on the terminal side in the above method modes, and the 1220 processing unit is configured to perform another operation on the terminal in the above method modes other than the receive and send operations. For example, in one implementation, processing unit 1220 is configured to perform processing step 602 and stage 603 on the terminal side in Figure 6. Transceiver unit 1210 is configured to perform receive and send operations in steps 601 and 604 in Figure 6, and / or transceiver unit 1210 is further configured to perform other receive and send steps on the terminal side in modes of this application. When the device is a chip, the chip includes a transceiver unit and a processing unit. The transceiver unit can be an input / output circuit or a communications interface. The processing unit is a processor, a microprocessor, or an integrated circuit, integrated onto the chip. Optionally, when the device is a terminal, reference is made to the device shown in Figure 13. In one example, the device may perform a function similar to that of the 910 processor in Figure 9. In Figure 13, the device includes: a 1301 processor, a 1303 data transmit processor, and a 1305 data receive processor. The 820 processing module in the mode shown in Figure 8 may be the 1301 processor in Figure 13, and it performs a corresponding function. The 810 transceiver module in the mode shown in Figure 8 may be the 1303 data transmit processor and the 1305 data receive processor in Figure 13. Although Figure 13 shows a channel encoder and a channel decoder, it can be understood that these modules do not constitute a limiting description of the modes, but are only an example. Figure 14 shows another form of the modalities. A 1400 processing apparatus includes modules such as a modulation subsystem, a central processing subsystem, and a peripheral subsystem. The communications device in the modalities can serve as a modulation subsystem within it. Specifically, the modulation subsystem can include a 1403 processor and a 1404 interface. The 1403 processor completes a function of the 820 processing module in the modality shown in Figure 8, and the 1404 interface completes a function of the 810 transceiver module. In another variant, the modulation subsystem includes a 1406 memory, a 1403 processor, and a program stored in WUUa / 4U44 / Ul 4000 memory and executed on the processor, and when executed by the processor, the program implements the method described in the modes. It should be noted that memory 1406 can be either non-volatile or volatile, and can be located within the modulation subsystem or in the processing apparatus 1400, provided that memory 1406 can be connected to the processor 1403. When the device in the modes is a network device, the network device can be shown in Figure 15. For example, device 150 is a base station.

The CU 1502 may include at least one 15022 processor and at least one 15021 memory.The CU 1502 and DU 1501 can communicate using an interface. A control plane interface can be Fs-C, for example, F1-C, and a user plane interface can be Fs-U, for example, F1-U. The CU 1502 component is primarily configured for baseband processing, base station control, and similar functions. The DU 1501 and CU 1502 can be physically installed together or separately, forming a distributed base station. The CU 1502 acts as the base station's control center, also known as the processing unit, and can be configured to perform baseband processing functions. For example, the CU 1502 can be configured to control the base station and perform network device operations using the previously described methods. Specifically, baseband processing in the CU and DU can be divided based on wireless network protocol layers. For example, the functions of a Packet Data Convergence Protocol (PDCP) and a higher protocol layer are implemented in the CU, while the protocol layers below PDCP, such as a Radio Link Control (RLC) and a Medium Access Control (MAC) layer, are implemented in the DU. Alternatively, the CU implements Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP) layer functions, while the DU implements Radio Link Control (RLC), MAC, and Physical (PHY) layer functions.

The DU may include at least one 15013 processor and at least one 15014 memory; the RU may include at least one 15011 antenna and at least one 15012 radio frequency unit; and the CU may include at least one 15022 processor and at least one 15021 memory. For example, in one implementation, the 15013 processor is configured to perform a processing step on the network device side in Figure 6. The 15012 radio frequency unit is configured to perform receive and send operations in steps 601 and 604 in Figure 6. In one example, CU 1502 can include one or more boards. A plurality of boards can support a radio access network of a single access standard (e.g., a 5G network), or they can support radio access networks of different access standards (e.g., an LTE network, a 5G network, or other networks). Memory 15021 and processor 15022 can serve one or more boards. In other words, one memory and one processor can be implemented on each board. Alternatively, a plurality of boards can share the same memory and processor. Additionally, a necessary circuit can be placed on each board. DU 1501 can include one or more boards. A plurality of boards can support a radio access network of a single access standard (e.g., a 5G network), or they can support radio access networks of different access standards (e.g., an LTE network, a 5G network, or other networks).The 15014 memory and 15013 processor can serve one or more boards. In other words, one memory and one processor can be implemented on each board. Alternatively, multiple boards can share the same memory and processor. Additionally, necessary circuitry can be placed on each board. All or some of the above modalities can be implemented using software, hardware, firmware, or any combination thereof. When software is used to implement the modalities, all or part of the modalities can be implemented in the form of a computer program product. The computer program product includes one or more computer instructions. When the computer instructions are loaded and executed on the computer, the procedure or functions according to the modalities of this application are generated, in whole or in part. The computer can be a general-purpose computer, a dedicated computer, a computer network, or another programmable device. The computer instructions can be stored on a computer-readable storage medium or transmitted from one computer-readable storage medium to another.For example, computer instructions can be transmitted from a. WUUa / 4U44 / Ul 4004 A computer-readable storage medium can be any usable medium accessible by a computer, or a data storage device, such as a server or data center, that integrates one or more usable media. The usable medium can be magnetic (such as a floppy disk, hard disk, or magnetic tape), optical (such as a high-density digital video disc, DVD), semiconductor (such as a solid-state disk, SSD), or similar. This means that the computer, computer, server, or data center can transmit data to another website, computer, server, or data center via a wired connection (e.g., coaxial cable, fiber optic cable, or digital subscriber line, DSL) or wireless connection (e.g., infrared, radio, or microwave). It should be understood that the processor can be an integrated circuit chip and has signal processing capabilities. In an implementation process, the steps in the preceding method modalities can be implemented using a hardware integrated logic circuit in the processor, or using software instructions. The processor can be a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or another programmable logic device, discrete gate, or logic device made of transistors or discrete hardware components. The processor can implement or perform the methods, steps, and logic block diagrams disclosed in the modalities of this application.The general-purpose processor may be a microprocessor, or the processor may be any conventional or similar processor. The steps in the methods disclosed with reference to the modalities of this application may be performed directly and completed by a hardware decoding processor, or they may be performed and completed by using a combination of hardware in the decoding processor and a software module. The software module may be located on a mature storage medium, such as random-access memory, flash memory, read-only memory, read-only programmable memory, electrically programmable memory, or a register. The storage medium is located in memory, and the processor reads information from memory and completes the steps in the above methods in combination with the processor hardware. It can be understood that the memory in the modalities of this application can be volatile or non-volatile memory, or it can include both. Non-volatile memory can be read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), or read-only memory. Electrically erasable programmable memory (EPROM, EEPROM) or flash memory. Volatile memory can be random access memory (RAM) and is used as an external cache. By way of example and not as a limiting description, RAM can be used in many forms, for example, static RAM (SRAM), dynamic RAM (DRAM), synchronous dynamic RAM (SDRAM), double data rate synchronous dynamic RAM (DDR SDRAM), enhanced synchronous dynamic RAM (ESDRAM), synchronous link DRAM (SLDRAM), and direct rambus RAM (DR RAM). In this application, "at least one" means one or more, and "plural of" means two or more. "And / or" describes an association relationship between associated objects and represents that three relationships can exist. For example, "A and / or B" can represent the following cases: Only A exists, both A and B exist, and only B exists, where A and B can be singular or plural. The character 7 generally indicates an "or" relationship between the associated objects. "At least one of the following" or a similar expression of the same refers to any combination of these elements, including a singular element or any combination of plural elements. For example, "at least one of a, b, c" can indicate: a, b, c, a and b, a and c, by and c, where a, by and c can be singular or plural. It should be understood that a modality or mode mentioned throughout the specification does not mean that features, structures, or particular characteristics related to that modality are included in at least one modality of this request. Therefore, “in a modality” or “in a mode” appearing throughout the specification does not necessarily refer to the same modality. Furthermore, these features, structures, or particular characteristics may be combined in one or more modalities in any appropriate manner. It should also be understood that the sequence numbers of the processes mentioned above do not signify execution sequences in the modalities of this request. The execution sequences of the processes must be determined based on the functions and internal logic of the processes and should not constitute any limitation on the implementation processes of the modalities of this request. Terms such as component, module, and system used in this specification refer to a computer-related entity, hardware, firmware, a combination of hardware and software, software, or running software. For example, a component can be, but is not limited to, a process running on a processor, a processor, an object, an executable file, a thread, a WUUa / 4U44 / Ul 4000 program and / or a computer. As illustrated using figures, both a computing device and an application running on the computing device can be components. One or more components can reside within a process and / or a thread of execution, and a component can be located on a computer and / or distributed among two or more computers. Furthermore, these components can be executed using various computer-readable media that store various data structures. Components can communicate, using a local and / or remote process and based on, for example, a signal that has one or more data packets (e.g., data from two components interacting with another component on a local system, on a distributed system, and / or across a network such as the Internet that interacts with other systems using the signal). It should also be understood that the first, second, and several numbers in this specification are used simply for differentiation to facilitate description, and are not intended to limit the scope of the modalities of this application. It should be understood that the term "and / or" in this specification describes only one association relationship between associated objects and represents that three relationships can exist. For example, A and / or B can represent the following three cases: Only A exists, both A and B exist, and only B exists. When only A or B exists, there is no limit to the number of A or B instances. For example, when only A exists, it can be understood as meaning there is one or more A instances. A person skilled in the art may be aware that, in combination with the examples described in the modalities disclosed in this specification, the algorithm units and steps can be implemented using electronic hardware or a combination of computer software and electronic hardware. Whether the functions are performed by hardware or software depends on the particular applications and the design constraints of the technical solutions. A person skilled in the art may use different methods to implement the described functions for each particular application, but it is not necessary to consider that the implementation goes beyond the scope of this request. An expert in the technique can clearly understand that, for the purpose of a convenient and brief description, for a detailed working process of the preceding system, apparatus and unit, reference is made to a corresponding process in the preceding modalities of the method, and no details are described again herein. In the various embodiments provided in this application, it should be understood that the disclosed system, apparatus, and method may be implemented in other ways. For example, the embodiment of the apparatus above is merely an example.
