Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a data transmission method, a terminal, and a network-side device. Background Technology

[0002] Some communication systems (e.g., 5G systems) support both four-step random access procedures and two-step random access procedures. In the four-step random access procedure, the terminal connects to the network-side equipment via four steps of messaging, while in the two-step random access procedure, the terminal connects to the network-side equipment via two steps of messaging. Currently, the terminal often only begins transmitting data after the access procedure is complete, resulting in significant data transmission latency. Summary of the Invention

[0107] Please see Figure 1 , Figure 1 This is a schematic diagram of the network architecture applicable to the implementation of this invention, such as... Figure 1 As shown, it includes terminal 11 and network device 12.

[0108] The terminal involved in this embodiment of the invention can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The name of the terminal device may differ in different systems; for example, in a 5G system, the terminal device can be called User Equipment (UE).

The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device.

Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in this embodiment of the invention.

[0109] The network device involved in this embodiment of the invention can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with wireless terminal devices through one or more sectors on the air interface, or other names.

Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission, etc.

[0111] Please see Figure 2 , Figure 2 This is a flowchart of a data transmission method provided in an embodiment of the present invention, such as... Figure 2 As shown, it includes the following steps:

[0112] Step 201: During the access process, the terminal sends a preamble, first data, and second data, wherein the size of the second data is greater than the size of the first data, and the time-frequency resources of the second data are determined based on at least one of the following:

[0113] The preamble, the resource location of the first data, the terminal's identification information, and the size of the second data.

[0114] In this embodiment of the invention, the first data can be referred to as small packet data, specifically, it can be a small data packet defined in the protocol. The second data can be referred to as large packet data or large block data, and its size is greater than the size of the first data.

[0115] In addition, in this embodiment of the invention, the first data and the second data are transmitted using different time-frequency resources.

[0116] The resource location of the first data mentioned above can be the time-frequency location of the first data.

[0117] In addition, in this embodiment of the invention, the network-side device can be instructed whether to send the second data through the indication information of the second data, or the size of the second data can be indicated to the network-side device through the indication information of the second data, and there is no limitation on this.

[0118] The identification information of the aforementioned terminal can also be referred to as the user ID.

[0119] In this embodiment of the invention, the access process described above can be a single-step access process. This allows for the direct transmission of first and second data during the single-step access process, thereby reducing the complexity of the terminal implementation and effectively reducing data transmission latency. Alternatively, the access process described above can also be a random access process.

[0120] In this embodiment of the invention, since a preamble, first data, and second data are sent during the access process, the first data and second data can be sent directly during the access process, thereby reducing the data transmission latency of the terminal.

[0121] As an optional implementation, the time-frequency resources of the determined second data include:

[0122] The time-frequency resources are determined from a preset time-frequency resource set based on at least one of the preamble, the resource location of the first data, the identification information of the terminal, and the size of the second data.

[0123] The aforementioned preset time-frequency resource set can be predefined by the protocol or configured by the network-side device.

[0124] Wherein, the time-frequency resource determined in the preset time-frequency resource set based on at least one of the preamble, the resource location of the first data, the identification information of the terminal, and the size of the second data may be a time-domain resource and / or frequency-domain resource that matches at least one of the preamble, the resource location of the first data, the identification information of the terminal, and the size of the second data selected from the preset time-frequency resource set.

[0125] Optionally, the time-domain location of the second data is determined in a preset time-frequency resource set based on at least one of the preamble, the resource location of the first data, the terminal's identification information, and the size of the second data; and / or

[0126] The frequency domain position of the second data is determined in a preset time-frequency resource set based on at least one of the preamble, the resource location of the first data, the identification information of the terminal, and the size of the second data.

[0127] Wherein, at least one of the above-mentioned time-domain positions can be the same as or different from at least one of the above-mentioned frequency-domain positions, and there is no limitation thereto.

[0128] For example: determining the frequency domain or time domain position of the second data based on the preamble, and determining the time domain or frequency domain position of the second data based on the resource position of the first data; or

[0129] The frequency domain or time domain position of the second data is determined based on the size of the second data, and the time domain or frequency domain position of the second data is determined based on the resource position of the first data; or

[0130] The frequency domain or time domain position of the second data is determined based on the preamble, and the time domain or frequency domain position of the second data is determined based on the terminal's identification information; or

[0131] The frequency domain position or time domain position of the second data is determined based on the size of the second data, and the time domain position or frequency domain position of the second data is determined based on the identification information of the terminal.

[0132] The determination of the frequency domain position of the second data based on the preamble can be achieved by determining the frequency domain position of the second data based on the mapping relationship between the preamble and the frequency domain position, or by dividing the identifier of the preamble by the number of time-domain units or frequency-domain units in the preset resource set, rounding down, and then determining the frequency domain position of the second data based on the rounding result. Similarly, the determination of the time-domain position of the second data based on the preamble can be achieved by determining the time-domain position of the second data based on the mapping relationship between the preamble and the time-domain position, or by dividing the identifier of the preamble by the number of time-domain units or frequency-domain units in the preset resource set, rounding down, and then determining the time-domain position of the second data based on the rounding result.

[0133] The aforementioned method of determining the time-domain position of the second data based on the resource position of the first data can be achieved by: determining the time-domain position of the second data based on the mapping relationship between the resource position and the time-domain position of the first data; dividing the identifier of the resource position of the first data by the number of time-domain units or frequency-domain units in the preset resource set, rounding down, and then determining the time-domain position of the second data based on the rounded result; or pre-defining the time delay between the first data and the second data, thereby determining the time-domain position of the second data based on the resource position of the first data and the time delay. Similarly, the aforementioned method of determining the frequency-domain position of the second data based on the resource position of the first data can be achieved by: determining the frequency-domain position of the second data based on the mapping relationship between the resource position and the frequency-domain position of the first data; dividing the identifier of the resource position of the first data by the number of time-domain units or frequency-domain units in the preset resource set, rounding down, and then determining the frequency-domain position of the second data based on the rounded result; or pre-defining the frequency-domain interval between the first data and the second data, thereby determining the frequency-domain position of the second data based on the resource position of the first data and the time delay.

[0134] The aforementioned method of determining the frequency domain position of the second data based on its size can be achieved by selecting a frequency domain resource whose size matches the size of the second data from the aforementioned preset time-frequency resource set, thereby determining the frequency domain position of the second data. Similarly, the aforementioned method of determining the time domain position of the second data based on its size can be achieved by selecting a time domain resource whose size matches the size of the second data from the aforementioned preset time-frequency resource set, thereby determining the time domain position of the second data.

[0135] The aforementioned method of determining the time-domain position of the second data based on the terminal's identification information can be achieved by determining the time-domain position of the second data based on the mapping relationship between the terminal's identification information and the time-domain position, or by taking the modulo of the terminal's identification information with a certain integer and then determining the time-domain position of the second data based on the modulo result. For example, taking the modulo of the terminal's identification information with integers such as 100 and 50, and using the modulo result relative to the time-domain position as the time-domain position of the second data. Similarly, the aforementioned method of determining the frequency-domain position of the second data based on the terminal's identification information can be achieved by determining the frequency-domain position of the second data based on the mapping relationship between the terminal's identification information and the frequency-domain position, or by taking the modulo of the terminal's identification information with a certain integer and then determining the frequency-domain position of the second data based on the modulo result. For example, taking the modulo of the terminal's identification information with integers such as 100 and 50, and using the modulo result relative to the time-domain position as the frequency-domain position of the second data.

[0136] It should be noted that the modulo and integer operations described above for determining the time-domain or frequency-domain position of the second data are merely illustrative examples. In some implementations, other operations can be performed on the preamble, the resource position of the first data, and the terminal's identification information, and then the time-domain and frequency-domain positions of the second data can be determined based on the operation results. For example, a bitwise XOR operation can be performed on the preamble, the resource position of the first data, and the terminal's identification information. For instance, the last 4 bits of the terminal ID can be XORed with the last 4 bits of the preamble ID to obtain 16 possible results from 0000 to 1111, which can be associated with 16 time-domain and frequency-domain positions or time-frequency positions, respectively.

[0137] Furthermore, in this embodiment of the invention, the time-domain position and frequency-domain position of the second data can be relative time-domain positions and relative frequency-domain positions, for example: the time-domain position equivalent to the starting time-domain position of the transmission time-frequency set of the second data, and the frequency-domain position equivalent to the starting frequency-domain position of the transmission time-frequency set of the second data. Of course, in some implementations, the absolute time-domain position and absolute frequency-domain position of the second data can also be determined, and this is not limited.

[0138] In the above embodiments, the time-frequency location of the second data can be determined in multiple ways. Furthermore, since the time-frequency resources of the second data can be determined based on the terminal's identification information, preamble, and the resource location of the first data, interference between second data transmissions can be reduced when multiple terminals simultaneously initiate access.

[0139] Optionally, when the frequency domain position of the second data is determined based on the size of the second data, the preamble is associated with the frequency domain position of the second data; and / or

[0140] The resource location of the first data is associated with the frequency domain location of the second data; and / or

[0141] The preamble, the resource location of the first data, and the frequency domain location of the second data are associated.

[0142] In this embodiment, by associating the preamble with the frequency domain position of the second data, the network-side device can determine the frequency domain position of the second data based on the preamble, and then receive the second data, when the frequency domain position of the second data is determined based on the size of the second data.

[0143] The association between the resource location of the first data and the frequency domain location of the second data can be achieved by pre-establishing a correlation between them, allowing the terminal and network-side devices to determine the other based on either one. Alternatively, the association can also occur when the frequency domain location of the second data is determined based on its size.

[0144] The association between the preamble, the resource location of the first data, and the frequency domain location of the second data can be such that these three elements are correlated, allowing the terminal and network-side devices to determine the other element based on any two of them. Alternatively, the association can also occur when the frequency domain location of the second data is determined based on its size; in this case, the preamble, the resource location of the first data, and the frequency domain location of the second data are correlated.

[0145] Optionally, the preset time-frequency resource set includes: multiple frequency domain resources of the same size; or

[0146] The preset time-frequency resource set includes multiple frequency domain resources of different sizes, wherein the size of the frequency domain resource of the determined second data matches the size of the second data.

[0147] In this embodiment, the preset time-frequency resource set for transmitting the second data can be equally divided or unequally divided. When the preset time-frequency resource set is unequally divided, explicit indication can be provided through the first data. For example, the indication information in the first data can be [0,1,2,3], where 0 indicates no large data blocks are being transmitted, 1 indicates the size of the large data block is at the first level, 2 indicates the size of the large data block is at the second level, and 3 indicates the size of the large data block is at the third level, where the first level is smaller than the second level, and the second level is smaller than the third level. This allows the second data to be mapped to resources of different sizes for transmission based on its size, thereby improving data transmission performance.

[0148] Optionally, if there are idle time-frequency resources in the preset time-frequency resource set that are not used by any terminal, and the idle time-frequency resources are used for the second data transmission during the access process at a certain moment, then the idle time-frequency resources are preferentially used for the second data transmission during the random access process.

[0149] In this implementation, the aforementioned idle time-frequency resources can be prioritized for the transmission of the second data. For example, if at a certain moment, time-frequency resources used for other services need to be used for the transmission of the second data in single-step access, then the time-frequency resources are prioritized for the transmission of the second block of data.

[0150] In addition, the aforementioned idle time-frequency resources, which are not used for the second data transmission during the access process, can be used for other service transmissions.

[0151] Among them, the aforementioned other service transmissions can be service transmissions other than the second data mentioned above, such as sending data transmissions other than the second data during single-step access.

[0152] In this embodiment, since idle time-frequency resources are used for other service transmissions under the above circumstances, resource utilization can be improved.

[0153] It should be noted that, in the embodiments of the present invention, at least one of the time-domain position and frequency-domain position of the second data can be determined by the above-described implementation methods. However, in some implementation methods, at least one of the time-domain position and frequency-domain position of the second data can be pre-configured, for example, the frequency-domain position of the second data can be pre-configured. Furthermore, in some implementation methods, the time-frequency resources of the second data can be determined from the currently available resources without configuring the above-described preset time-frequency resource set. For example, the preset time-frequency resource set can be omitted, and the time-frequency resources of the second data can be determined directly from the currently available resources based on at least one of the preamble, the resource position of the first data, the terminal's identification information, and the size of the second data.

[0154] As an optional implementation, the first data includes indication information for the second data, the indication information being used to indicate at least one of the following:

[0155] The size of the second data, and whether to send the second data;

[0156] Alternatively, the size of the second data may be implicitly indicated by at least one of the following:

[0157] The preamble, the resource location of the first data, and the identification information of the terminal.

[0158] The above indication information can be implemented using one or two bits. For example, one bit can indicate whether to send the second data, two bits can indicate whether to send the second data, and the size level of the second data.

[0159] The indication information for the second data is included in the first data; that is, during the access process, the first data contains the indication information for the second data. This indication information can indicate whether second data has been sent and its size. After receiving the first data, the network determines whether second data has been sent and its size based on the decoding result, according to the indication information for the second data in the first data.

[0160] The size of the second data can be indicated by the preamble, for example, by determining the size of the second data based on the mapping relationship between the preamble and the size of the second data.

[0161] The size of the second data can be indicated by the resource location of the first data, for example, by determining the size of the second data based on the mapping relationship between the resource location of the first data and the size of the second data.

[0162] The size of the second data can be indicated by the identification information of the terminal, for example, by determining the size of the second data based on the mapping relationship between the terminal's identification information and the size of the second data.

[0163] As an optional implementation, the uplink beam direction for transmitting the preamble, the first data, and the second data is the same.

[0164] Specifically, this could mean that the uplink beam direction is the same when the same terminal sends the preamble, the first data, and the second data in a single transmission.

[0165] As an optional implementation, the preamble, the first data, and the second data are sent through the same message during the access process.

[0166] The aforementioned "same message" refers to message 1 during the access process, such as the message sent by the terminal during a single-step access process.

[0167] The above message transmission can occupy multiple time domain positions, corresponding to the preamble, the first data, and the second data, respectively.

[0168] By sending the preamble, first data, and second data through the same message, the data transmission latency of the terminal can be further reduced.

[0169] In this embodiment of the invention, the terminal sends a preamble, first data, and second data during the access process. The size of the second data is greater than the size of the first data, and the time-frequency resources of the second data are determined based on at least one of the following: the preamble, the resource location of the first data, the terminal's identification information, and the size of the second data. By sending the preamble, first data, and second data during the access process, the data transmission latency of the terminal can be reduced.

[0181] Wherein, the size of the second data is indicated by the indication information, or the size of the second data is implicitly indicated by at least one of the following:

[0188] Optionally, if there are idle time-frequency resources in the preset time-frequency resource set that are not used by any terminal, the idle time-frequency resources are used for other service transmissions.

[0189] Optionally, if the idle time-frequency resources are used for the second data transmission during the access process at a certain moment, then the idle time-frequency resources shall be preferentially used for the second data transmission during the access process.

[0190] Optionally, the indication information is used to indicate at least one of the following:

[0191] The size of the second data, and whether to send the second data.

[0192] Optionally, the indication information is included in the first data.

[0193] Optionally, the uplink beam directions of the preamble, the first data, and the second data are the same.

[0194] Optionally, the preamble, the first data, and the second data are received through the same message during the access process.

[0195] It should be noted that this embodiment is as a comparison with... Figure 2 The implementation methods of the network-side devices shown in the embodiments can be found in the following examples. Figure 2 The related descriptions of the embodiments shown will not be repeated in this embodiment to avoid repetition, and can achieve the same beneficial effects.

[0196] The data transmission method provided in the embodiments of the present invention will be illustrated below through several examples:

[0197] Example 1

[0198] In this embodiment, the time-frequency positions of the preamble and the first data (i.e., the small packet data) are as follows: Figure 4 As shown, taking 4 Synchronization Signal Blocks (SSBs) and 32 preambles as an example, each preamble and SSB corresponds to a time-frequency position of the first data transmission.

[0199] In actual transmission, there is a delay of 1 between the terminal sending the preamble and sending the payload (first data). When sending the second data (i.e., the large block of data), the delay of 2 between the second data and the first data transmission can be determined first, and then the time-frequency resources for sending the second data need to be determined. A schematic diagram of the second data transmission time relationship is shown below. Figure 5 As shown. Figure 5 In the diagram, the first vertical line indicates that the network has received the first data, and the second long vertical line indicates that the network decodes the information in the first data to determine if there is any second data to be sent. If there is second data to be sent, the terminal determines the time-frequency resource for this second data transmission from a preset time-frequency location based on at least one of the following: the preamble, the time-frequency location of the first data transmission, and the terminal identification information. If there are time-frequency resources in the preset second data transmission time-frequency resources that are not used by any terminal, then those time-frequency resources can be used for other services.

[0200] Specifically, a predefined set of time-frequency locations can be established, containing N physical resource blocks (PRBs) and M time units (which can be symbols or time slots). The N PRBs are divided into K subsets, each consisting of consecutive PRBs. The number of PRBs in each subset can be the same or different. This effectively divides the N PRBs into K frequency domain sets, either equally or unequally. If the size of the second data segment differs, the second data is mapped to different sized frequency domain resources for transmission based on its size. The K frequency domain sets and M time units together determine the M*K time-frequency locations for large data transmission. A time-frequency location is determined for large data transmission based on at least one of the following: preamble, time-frequency location for small packet data transmission, and user ID.

[0201] Example 2

[0202] In this embodiment, N PRBs are divided into K subsets. Taking an example with 32 preambles and 16 time-frequency positions in the small packet data (it should be noted that 32 and 16 are merely examples and not limitations on the actual size). Assume the second data's time-frequency position set consists of 16 PRBs and 8 time slots. For example... Figure 6 As shown, the 16 PRBs are divided into 4 subsets, with each subset containing 4 PRBs.

[0203] The relative time-domain position and frequency-domain position of the second data are determined by taking modulo and rounding, based on at least one of the preamble, the time-frequency position of the first data transmission, and the user ID. The relative time-domain position is the time-domain position relative to the start position of the large data transmission time-frequency set. The time delay between the start position of the second data transmission time-frequency set and the start position of the first data transmission / the start position of the preamble transmission / the start position of the SSB reception can be preset or indicated by the network side via the SSB.

[0204] Taking the preamble ID and the time-frequency position ID for transmitting small data packets as examples, the preamble ID can be divided by 8 and rounded (or the number of frequency domain subsets can be moduloed) to map the 32 preambles onto 4 subsets, thus obtaining the frequency domain position. The time-frequency position ID for transmitting the first data is then moduloed by M (M = 8, where M is the number of time units) to obtain the relative time domain position. The specific mapping diagram is shown below. Figure 6 As shown.

[0205] It should be noted that the modulo and integer operations used here to obtain the mapping pattern are only an example. Other operations can also be used to obtain the mapping pattern, such as bit XOR. For example, XORing the last 4 bits of the user ID with the last 4 bits of the preamble ID will yield 16 results from 0000 to 1111, which can be associated with 16 time-domain positions, frequency-domain positions, and time-frequency positions, respectively.

[0206] Example 3

[0207] In this embodiment, the N PRBs are divided into K subsets, each subset containing a different number of PRBs. Taking a first data set with 16 time-frequency positions as an example (the numbers 32 and 16 are merely examples and not considered as a specific size limitation), the second data set is assumed to consist of 30 PRBs and 8 time slots. Figure 7 As shown, the 30 PRBs are unequally divided into 4 subsets, with each subset containing 16, 8, 4, and 2 PRBs respectively.

[0208] The size of the second data sent by the terminal varies. When the second data is relatively small, a frequency domain resource with fewer PRBs can be selected; when the second data is relatively large, a frequency domain resource with more PRBs can be selected.

[0209] Using modulo and integer methods, the relative time-domain position and frequency-domain position of the second data are determined based on at least two of the following: the preamble, the time-frequency position of the small packet data transmission, and the user ID. The relative time-domain position is the time-domain position relative to the start position of the second data transmission time-frequency set. The time delay between the start position of the second data transmission time-frequency set and the start position of the first data transmission / the start position of the preamble transmission / the start position of the SSB reception can be preset or indicated by the network side via the SSB.

[0210] Optionally, instructions can be given implicitly, as follows:

[0211] Different sizes of frequency domain resources correspond to different preambles. For example, the result of taking the modulo of the number of frequency domain subsets for each associated frequency domain resource is the same. The terminal compares the size of the second data to be transmitted with a preset data block threshold to determine which frequency domain subset to use for transmission, and then randomly selects a preamble from those associated with that subset. On the network side, the network can determine the frequency domain resource used for transmitting the second data by taking the modulo of the number of frequency domain subsets based on the detected preamble ID. This implicit indication can thus indicate the size of the second data.

[0212] Furthermore, the terminal takes the modulo of the time-frequency location ID of the first data sent by M (M=8 is the number of time units) to obtain the relative time-domain location, as shown in the specific mapping diagram. Figure 7 As shown.

[0213] Optionally, the size of the second data sent by the terminal can be explicitly indicated in the first data to indicate the set of frequency domain resources used by the second data.

[0214] It should be noted that the modulo and integer operations used here to obtain the mapping pattern are only examples. Other operations, such as bit XOR, can also be used to obtain the mapping pattern.

[0215] Example 4

[0216] In this embodiment, the N PRBs are divided into K subsets. Taking the example of 32 preambles and 16 time-frequency positions in the first data (the 32 and 16 are merely examples and not intended as a specific size limitation), the frequency domain positions of the second data are assumed to consist of 16 PRBs. Figure 8 As shown, the 16 PRBs are divided into 4 subsets, with each subset containing 4 PRBs.

[0217] Using modulo and integer methods, based on at least one of the preamble, the time-frequency position of the first data transmission, and the user ID, the relative time-domain position and frequency-domain position of the second data are determined (wherein, the relative time-domain position is the time delay between the transmission of the second data and the transmission of the first data by different terminals, and this time delay can be the same or different).

[0218] Taking the preamble ID and user ID as examples, the preamble ID can be divided by 8 and rounded (or the number of frequency domain subsets can be moduloed) to map the 32 preambles onto 4 subsets, obtaining the frequency domain position. The user ID is modulo 100 to obtain the relative time domain position. The time delay between sending the second data and sending the first data can be the same or different for different terminals. A specific mapping diagram is shown below. Figure 8 As shown.

[0219] It should be noted that the modulo and integer operations used here to obtain the mapping pattern are only examples. Other operations, such as bit XOR, can also be used to obtain the mapping pattern.

[0220] Example 5

[0221] In this embodiment, N PRBs are divided into K subsets, each subset containing a different number of PRBs. For example, the first data has 16 time-frequency positions, with 32 preambles (the 32 and 16 are merely examples and not intended as a specific size limitation). Assume the second data's frequency domain positions consist of 30 PRBs. Figure 9As shown, the 30 PRBs are unequally divided into 4 subsets, with each subset containing 16, 8, 4, and 2 PRBs respectively.

[0222] Using modulo and integer methods, based on at least two of the following: the preamble, the time-frequency position of the first data transmission, and the user ID, the relative time-domain position and frequency-domain position of the second data are determined (wherein, the relative time-domain position is the time delay between the transmission of the second data and the transmission of the first data by different terminals, and this time delay can be the same or different).

[0223] Alternatively, instructions can be given implicitly, as follows:

[0224] Different sizes of frequency domain resources correspond to different preambles. For example, the result of taking the modulo of the number of frequency domain subsets for each frequency domain resource is the same. The terminal compares the size of the second data to be transmitted with a preset data block threshold to determine which frequency domain subset to use for transmission. Then, it randomly selects a preamble from the preambles associated with that frequency domain subset. (On the network side, the network can determine the frequency domain resource used for large data transmission by taking the modulo of the number of frequency domain subsets based on the detected preamble ID.) The size of the second data can be indicated through this implicit instruction.

[0225] Furthermore, the user ID is modulo 100 to obtain the relative time domain position. The time delay for different terminals to send the second data relative to the time delay for sending the first data can be the same or different. The specific mapping diagram is as follows. Figure 9 As shown.

[0226] Optionally, the size of the second data sent by the terminal can be explicitly indicated in the small packet data, that is, the set of frequency domain resources used by the second data.

[0227] It should be noted that the modulo and integer operations used here to obtain the mapping pattern are only examples. Other operations, such as bit XOR, can also be used to obtain the mapping pattern.
