After the first device receives the MSG1 message carrying the random number sent by the second device, step S603 can be performed to send a first indication message to the second device through a MSG2 message, wherein the resource information can be sent through the MSG2, and the first indication information is used to indicate that the second device needs to receive a downlink command.

[0143] The second device can send second indication information and the device ID of the second device to the first device by using a MSG3 message according to the resource information occupation after receiving the first indication information, wherein the second indication information is used to represent whether the second device can receive the downlink command and the time node at which the downlink command can be received.

[0144] The first device can determine whether the second device with the device ID can receive the downlink command according to the second indication information after receiving the second indication information, and if yes, the first device can send the downlink command to the second device at the time node at which the second device can receive the downlink command represented by the second indication information.

[0145] For example, the second indication information represents that the second device can receive the downlink command at a time node within T1 time, the first device can send the downlink command to the second device within T1 time after receiving the second indication information sent by the second device, and for another example, the second indication information represents that the second device can receive the downlink command at a time node after T1 time, the first device can send the downlink command to the second device after waiting for T1 time after receiving the second indication information sent by the second device, and it should be noted that T1 can be set by the second device according to the resource information occupation of the second device, which is not limited herein.

[0146] In some possible implementation manners, as shown in FIG. 4, the first device can send a first message carrying first indication information to the second device by performing step S701 (here, the first message is taken as an initial message for example, and of course, the first message can also be other messages, which is not limited herein), so as to send the first indication information to the second device by using the initial message, wherein the first indication information is used to indicate that the second device needs to receive the downlink command.

[0147] The second device can return second indication information and the device ID of the second device to the first device by using a MSG1 message according to the resource information occupation after receiving the first indication information, wherein the second indication information is used to represent whether the second device can receive the downlink command and the time node at which the downlink command can be received.

[0148] After the first device receives the second indication information, the first device can determine whether the second device with the device ID can receive the downlink command according to the second indication information, and if so, the first device can send the downlink command to the second device at a time node at which the second device can receive the downlink command represented by the second indication information.

[0149] The data transmission method provided by the present application will be described below in combination with the data transmission system shown in FIG. 5 of the present application. In order to make the technical solutions of the present application clearer and easier to understand, the data transmission method provided by the embodiments of the present application will be described below in combination with the above-mentioned embodiments and corresponding drawings, taking the first device as the execution subject. As shown in FIG. 5, the data transmission method provided by the embodiments of the present application can include:

[0150] S801: configuring resource information required by at least one second device for data transmission.

[0151] The first device can configure resource information required by at least one second device for data transmission, wherein the resource information can include one or more target resource information. The target resource information herein can be taken as a resource block or a resource unit. The target resource information can include frequency domain resource information and / or time domain resource information, that is, the target resource information can include frequency domain resource information or time domain resource information, or can include both frequency domain resource information and time domain resource information. The frequency domain resource information refers to the allocation and management of signal resources in the frequency dimension. The time domain resource information refers to the allocation and management of signal resources in the time dimension.

[0152] For example, the frequency domain resource information can include at least one of a frequency domain resource multiplexing number and a frequency domain resource bandwidth. The frequency domain resource multiplexing number refers to the number of frequency bands divided in the frequency domain, and each frequency band can be an independent frequency domain resource. The frequency domain resource bandwidth refers to the frequency range of the transmitted signal.

[0153] The time domain resource information can include at least one of a time domain resource number, a number of time domain resources in a time unit, and a time domain resource length. The time domain resource number is the number of time periods divided in the time domain, and a time period herein can be regarded as a time domain resource information. The time domain resource allocation herein can be allocated in a time division multiplexing (TDM) manner.

[0154] The number of time domain resources in a time unit refers to the number of time domain resource information included in a time unit. The time unit can be a symbol, a time slot, a subframe, a frame, or a chip length.

[0155] Wherein, the chip length is the basic time unit of the signal. A chip is an element in a pseudo-random code sequence used for encoding and decoding signals. The length of a chip is very short, usually in the order of nanoseconds.

[0156] A symbol is a unit of signal used to represent data in the modulation process. In digital communication, a symbol can carry a certain amount of bit information. The duration of a symbol depends on the modulation method, for example, in Quadrature Phase Shift Keying (QPSK) modulation, a symbol may carry 2 bits of information, while Quadrature Amplitude Modulation (QAM) may carry 4 bits of information.

[0157] A time slot is the basic time unit in Time Division Multiple Access (TDMA). In a TDMA system, time is divided into multiple time slots, each of which can be allocated to different users or services. The length of a time slot is usually fixed, used to realize multi-user access in time.

[0158] A frame is a fixed time interval used to organize data transmission in a communication system. A frame can include multiple time slots or subframes, and is usually used for the transmission of synchronization and control signals.

[0159] A subframe is a smaller part of the frame structure. In some communication systems, such as LTE, a frame is divided into multiple subframes, each containing a certain number of symbols.

[0160] The length of the time domain resource refers to the length of time maintained by a time domain resource information.

[0161] In some possible implementation manners, the resource information can further include a quantity of target resource information corresponding to the second device, wherein the quantity of target resource information corresponding to the second device can include a quantity of frequency domain resource information corresponding to the second device (also referred to as a first quantity) and / or a quantity of time domain resource information corresponding to the second device (also referred to as a second quantity), and in the case that the target resource information is frequency domain resource and time domain resource, the quantity of target resource can include a quantity of resource blocks corresponding to the second device, wherein the resource block refers to a resource unit including time domain resource and frequency domain resource.

[0162] In some possible implementation manners, the target resource information can be a random access resource, i.e., a random access occasion, and the random access occasion is used for the device to transmit MSG1.

[0163] In some possible implementation manners, the resource information can further include a sequence number corresponding to the second device, for example, a random access preamble. Each target resource can correspond to one or more sequence numbers, and the device determines the corresponding sequence number and target resource according to the device identifier configuration sequence. For example, one target resource corresponds to one sequence number, there are three target resources in total, and there are three second devices. Then, the second device in the first configuration sequence corresponds to the sequence number of the first target resource, the second device in the second configuration sequence corresponds to the sequence number of the second target resource, and the second device in the third configuration sequence corresponds to the third target resource. For another example, one target resource corresponds to two sequence numbers, there are three target resources in total, and there are six second devices. Then, the second device in the first configuration sequence corresponds to the first sequence number of the first target resource, the second device in the second configuration sequence corresponds to the second sequence number of the first target resource, the second device in the third configuration sequence corresponds to the first sequence number of the second target resource, and the second device in the fourth configuration sequence corresponds to the second sequence number of the second target resource, and so on. For another example, one target resource corresponds to two sequence numbers, there are three target resources in total, and there are three second devices. Then, the second device in the first configuration sequence corresponds to the first sequence number and the second sequence number of the first target resource, the second device in the second configuration sequence corresponds to the first sequence number and the second sequence number of the second target resource, and so on. When the second device receives the resource information, the second device selects a sequence number in the resource information. The second device transmits the selected sequence number on the determined resource. When the second device corresponds to multiple target resources, the second device can directly correspond to the sequence numbers corresponding to the multiple target resources.

[0164] S802: transmitting the resource information to the second device, so that the second device determines target resource information corresponding to a target second device from the resource information to transmit data.

[0165] The first device can transmit the configured resource information to the second device, so that the second device determines target resource information corresponding to a target second device from the resource information to transmit data. The resource information can be in the form of a broadcast message transmitted to the second device. The second device determines whether the broadcast message is sent to itself by the device identifier in the broadcast message. When the broadcast message includes the identifier information of the second device, it is considered that the broadcast message is sent to itself.

[0166] The resource information can also be sent by dedicated signaling. For example, if the configured resource information is required by one second device for data transmission, the resource information can be sent to the second device. If the configured resource information is required by multiple second devices for data transmission, the resource information can be sent to each of the multiple second devices, so that the second devices obtain the corresponding target resource information and use the target resource to communicate with the first device.

[0167] In this embodiment, the first device can configure resource information required by at least one second device for data transmission, wherein the second device can correspond to one or more target resource information, and the target resource information can include frequency domain resource information and / or time domain resource information. Then the resource information is sent to the second device, so that the second device determines the target resource information corresponding to the target second device from the resource information for data transmission. Since the first device configures one or more target resource information corresponding to each second device, the second device can determine the target resource information corresponding to itself after receiving the resource information. In this way, the first device achieves the configuration of the resource information required by at least one second device for data transmission.

[0168] The above embodiment can be referred to as embodiment one, which mainly introduces the process of configuring resource information by the first device and sending the resource information to the second device. In the following, the process of sending the resource information by the first device to the second device in the present application will be introduced, which can be referred to as embodiment two.

[0169] In embodiment two, the first device can send a first message to the second device for sending resource information to the second device, wherein the first message can be a paging message, and the resource configured in the message is used for the second device to send MSG1. Or the first message can be MSG2, which is used for the second device to send MSG3 or subsequent uplink data. Or the first message is a downlink message, such as inventory message or PRDCH (physical reader to device channel) transmission message. When the first message only includes frequency domain resource information, the first message can be a time domain start marker, or means that each subsequent downlink signaling can be a time domain start marker.

[0170] In some possible implementation manners, the first device can send the first message and the second message to the second device, as shown in FIG. 6, where the first message can be used to configure device identification information, and the second message can be used to configure resource information. That is, the resource information is sent to the second device by using the first message, and the device identification information is sent to the second device by using the second message, where the device identification information in the first message and the resource information in the second message correspond to each other. The first message can be a paging message, where the first message can include the number of time domain resources. The second message is a downlink message, and the second message can be used to indicate the start mark of the time domain. The second message can be any downlink message, for example, an inventory message, a MSG2 or a message transmitted on a PRDCH, which is used to allocate resource information of an uplink message corresponding to the downlink message. If the first message corresponds to multiple second messages, that is, the number of time domain resources included in the first message is multiple, the sending sequence and the resource of the second message can correspond to the device identification of the first message. For example, the device identification in the first message includes 12 devices, the first message corresponds to three second messages, and each second message includes four target resource information. The target resource information in the first second message corresponds to the first device to the fourth device among the 12 devices, the target resource information in the second second message corresponds to the fifth device to the eighth device among the 12 devices, and the target resource information in the third second message corresponds to the ninth device to the twelfth device among the 12 devices. If each second message includes five target resource information, the target resource information in the first second message corresponds to the first device to the fifth device among the 12 devices, the target resource information in the second second message corresponds to the sixth device to the tenth device among the 12 devices, and the first two resources in the target resource information in the third second message correspond to the eleventh device to the twelfth device among the 12 devices. There are still three resources in the target resource information in the third second message, which can be used by the twelfth device in this case.

[0171] In some possible implementation manners, the first device can send the first message and the second message to the second device, wherein the first message is used to configure the device identification information, and the second message is used to configure the resource information and the device identification information. The device identification information in the first message is used to page the device (i.e., to make the device know that it needs to receive data or needs to trigger an access procedure), and the second message is used for the device to determine the target resource information, i.e., the resource information in the second message and the device identification information correspond to each other. The first message can be a paging message, and the second message can be a downlink message. Optionally, when the frequency domain resource information is included in the second message, the second message can be used to indicate the start marker of the time domain. The second message can be any downlink message, such as an inventory message, a MSG2, or a message transmitted on a PRDCH, which is used to allocate resource information of an uplink message corresponding to the downlink message. If the first message corresponds to multiple second messages, i.e., the number of time domain resources included in the first message is multiple, the sending sequence and the resource of the second message can correspond to the device identification of the first message. For example, taking one device corresponding to one resource as an example, the device identification included in the first message includes 12 devices, the first message corresponds to three second messages, each second message includes four target resource information and four device identifications, the target resource information in the first second message corresponds to the first device to the fourth device of the four device identifications in the second message, the target resource information in the second second message corresponds to the first device to the fourth device of the four device identifications in the second message, and the target resource information in the third second message corresponds to the first device to the fourth device of the four device identifications in the second message. If each second message includes five target resource information, the target resource information in the first second message corresponds to the first device to the fifth device of the five device identifications in the second message, the target resource information in the second second message corresponds to the first device to the fifth device of the five device identifications in the second message, and the target resource information in the third second message corresponds to the first device to the fifth device of the five device identifications in the second message. The device identification in the third second message can be a device that has not successfully received a reply message of the device, and the reply message can be a MSG1.

[0172] The message can be data, configuration signaling, a MAC CE, or any content.

[0173] For example, the first message below is taken as an initial message, which carries resource information, so that the initial message can be used to send the resource information to the second device. Optionally, the initial message can be taken as a start mark. When the second device receives the initial message, it can parse the resource information to determine the corresponding target resource information.

[0174] In some possible implementation manners, the first message is MSG2. The resource information can be carried in the MSG2, so that the MSG2 can be used to send the resource information to the second device. Optionally, the MSG2 can be taken as a start mark. When the second device receives the MSG2, it can parse the resource information to determine the corresponding target resource information.

[0175] In some possible implementation manners, the first device can send a first message to the second device to page the second device, and carry resource information in the initial message, so that the initial message can be used to send the resource information to the second device. After it is determined that the second device receives the initial message, the second device can be sent a second message (for example, the second message below is taken as an inventory message, and of course, the second message can also be other messages, which is not limited herein) and the second message can be taken as a start mark. When the second device receives the inventory message, it can parse the resource information to determine the corresponding target resource information.

[0176] In some possible implementation manners, the first device can send a first message (for example, the initial message) to the second device to page the second device. After it is determined that the second device receives the initial message, the second device can be sent an inventory message, and the resource information can be carried in the inventory message, so that the inventory message can be used to send the resource information to the second device. When the second device receives the inventory message, it can parse the resource information to determine the corresponding target resource information.

[0177] In some possible implementation manners, the first device can further send device identification information to the second device, so that the second device determines the corresponding target resource information according to the device identification information. The device identification information can include device identification and / or a configuration order of the device identification. The device identification (also referred to as device ID) can be used to uniquely identify a second device. For example, the device identification information is a device identification list, which includes device identification. The order of the device identification in the list is the order (or can be referred to as the configuration order) of the device identification in the device identification list. For example, the list order of the first device identification is the first, and the list order of the second device identification is the second. The list order can be identified by an index. For example, the first order is #0, and the second order is #1. The device identification can be device#0, device#1, and the like. The configuration order of the device identification can be {device#0, device#1, device#2, device#3}. Each second device can correspond to one or more target resource information according to the configuration order of the device identification. For example, the first device is the first device in the configuration order of the device identification, and the second device with the device identification of device#0 is allocated three frequency domain resource information. The second device device#0 can determine the corresponding three frequency domain resource information according to the configuration order of the device identification.

[0178] The following describes a process of sending resource information and device identification information to the second device in this application. This embodiment can be referred to as embodiment three.

[0179] In embodiment three, the first device can send a first message (for example, an initial message) to the second device, and carry resource information and device identification information in the initial message. Therefore, the initial message can be used to send the resource information and the device identification information to the second device. Optionally, the initial message can be used as a start mark. When the second device receives the initial message, the resource information can be parsed to determine the corresponding target resource information according to the device identification information. The start mark is the start of a time unit.

[0180] In some possible implementation manners, the first device can send a first message (for example, an initial message) to the second device to page the second device, and carry the resource information and the device identification information in the initial message, so that the initial message can be used to send the resource information and the device identification to the second device, and the sending of the resource allocation information inventory message to the second device can be marked as a start after it is determined that the second device receives the initial message, and when the second device receives the inventory message, the corresponding target resource information can be determined according to the device identification information.

[0181] In some possible implementation manners, the first device can send a first message (for example, an initial message) to the second device to page the second device, and carry the device identification information in the initial message, that is, the initial message can be used to send the device identification information to the second device, and optionally, the inventory message can be sent to the second device after it is determined that the second device receives the initial message, and the resource information can be carried in the inventory message, so that the inventory message can be used to send the resource information to the second device, and when the second device receives the inventory message, the resource information can be parsed to determine the corresponding target resource information according to the device identification information.

[0182] In some possible implementation manners, the initial message can also carry the resource information, and the inventory message can carry the device identification information, so that the initial message can be used to send the resource information to the second device, and the inventory message can be used to send the device identification information to the second device.

[0183] In some possible implementation manners, for example, when the second device does not have a storage function or has a poor storage function, in order to avoid the device identification information being unable to be acquired from the initial message or the device identification information in the initial message being unable to be stored, the device identification information can also be carried in the inventory message.

[0184] The process of sending the resource information and the device identification information to the second device is briefly introduced in Embodiment Three. In the following, the process of sending the resource information and the device identification information to the second device is introduced in the scenario that one second device corresponds to one target resource information and the scenario that one second device includes multiple target resource information.

[0185] In Embodiment Four, the process of sending the resource information and the device identification information to the second device in the scenario that one second device corresponds to one target resource information is introduced. For example, as shown in FIG. 7, the first device can send an initial message to the second device, and carry the resource information and the device identification information in the initial message, so as to send the resource information and the device identification information to the second device by using the initial message. Meanwhile, the initial message can be used as a start mark. When the second device receives the initial message, the resource information can be resolved to determine the corresponding target resource information according to the device identification information. It should be noted that, in this case, one time unit only includes one time domain resource information and the initial message is used as the start mark. After the second device receives the initial message, the resource information is directly determined. Therefore, in this case, the target resource information in the resource information can only include frequency domain resource information, that is, only the frequency domain resource information and the device identification information are carried in the initial message. Of course, the time domain resource information can also be included. When the time domain resource information is included, the device can determine the target resource information according to the time-frequency domain resource position. Here, the actual situation can be set, which is not limited herein.

[0186] In some possible implementation manners, for example, as shown in FIG. 8, the first device can send a first message (for example, the initial message) to the second device to page the second device, and carry the resource information and the device identification information in the initial message, so that the resource information and the device identification can be sent to the second device by using the initial message, and the sending of the resource allocation information inventory message to the second device can be marked as the start after the initial message is determined to be received by the second device, and the resource information can be parsed when the inventory message is received by the second device, so as to determine the corresponding target resource information according to the device identification information. It should be noted that the initial message is used to page the second device and send the resource information, and the second device needs to receive the inventory message again after the initial message is sent to the second device, so as to perform the operation of parsing the resource information. Therefore, the target resource information in the resource information needs to include the time domain resource information.

[0187] In some possible implementation manners, the first device can send a first message (for example, the initial message) to the second device to page the second device, and carry the device identification information in the initial message, that is, the device identification information is sent to the second device by using the initial message, and the inventory message can be sent to the second device after the initial message is determined to be received by the second device, and the resource information is carried in the inventory message, so that the resource information can be sent to the second device by using the inventory message, and the resource information can be parsed when the inventory message is received by the second device, so as to determine the corresponding target resource information according to the device identification information. It should be noted that the second device determines the target resource information from the resource information according to the device identification information carried in the initial message. It can be seen that there is a corresponding relationship between the device identification information carried in the initial message and the resource information carried in the inventory message. For example, the device identification information is the configuration order of the device identification, and the second device needs to determine the corresponding target resource information from the resource information according to the position of the device identification in the configuration order of the device identification.

[0188] In some possible implementation manners, as shown in FIG. 9, for example, when the second device does not have a storage function or has a poor storage function, or when it is necessary to reassign the correspondence between the device and the resource, in order to avoid the situation that the device identifier information cannot be obtained from the initial message, the device identifier information can also be carried in the inventory message. The device identifier information in the initial message is the identifier information of all second devices that need to be paged, and the device identifier information included in the inventory message is the identifier information of the device corresponding to the resource in the inventory. For example, taking the device identifier information of all second devices that need to be paged as an example, for example, the device identifiers of all second devices that need to be paged included in the initial message are device#0 to device#7, the device identifiers of the second devices of device#0 to device#3 can be included in the first inventory message, and the device identifiers of the second devices of device#4 to device#7 can be included in the second inventory message. Therefore, the second device can directly perform the resource information operation according to the device identifier information carried in the inventory message, and it needs to be noted that the target resource information in the resource information can only include the frequency domain resource information, and does not include the time domain resource information, that is, only the frequency domain resource information and the device identifier information are carried in the initial message. The specific principle is similar to the related description of FIG. 8, and thus is not described herein.

[0189] In some possible implementation manners, one time unit can also include multiple time domain resource information. As an example, as shown in FIG. 10, one time unit includes two time domain resource information, which are respectively time domain resource information with an identifier sequence number of Slot#0 and time domain resource information with an identifier sequence number of Slot#1. Therefore, the resource information herein needs to include the time domain resource information, that is, the initial message is used to send the time domain resource information, the frequency domain resource information and the device identifier information to the second device.

[0190] The initial message and the inventory message in the above examples are examples, for example, the resource allocation method in the example in FIG. 7 can be applied to MSG2, MSG4 or any downlink message, that is, the initial message can be MSG2, MSG4 or any downlink message. The inventory message in FIG. 8 can be MSG2 or any downlink message. The inventory message in FIG. 9 can be MSG2 or any downlink message. The inventory message in FIG. 10 can be MSG2 or any downlink message.

[0191] In the embodiment five, the process of sending the resource information and the device identification information to the second device is introduced in the scenario that one second device corresponds to multiple target resource information.

[0192] In the embodiment, for example, as shown in FIG. 11, the first device can send the resource information and the device identification information to the second device by using the initial message, and the initial message can be used as a start mark. When the second device receives the initial message, the resource information can be parsed to determine the corresponding target resource information according to the device identification information. It should be noted that the target resource information in the resource information can only include the frequency domain resource information, and the initial message can include the time domain resource information. The specific principle is the same as that in the embodiment four, and details can be referred to the related description in the embodiment four, and thus, no redundant description is made here.

[0193] In some possible implementation manners, for example, as shown in FIG. 12, the first device can send the resource information and the device identification information to the second device by using the initial message. After determining that the second device receives the initial message, the first device can send the resource allocation information inventory message to the second device as a start mark. When the second device receives the inventory message, the resource information can be parsed to determine the corresponding target resource information according to the device identification information. It should be noted that the target resource information in the resource information needs to include the time domain resource information. The specific principle is the same as that in the embodiment four, and details can be referred to the related description in the embodiment four, and thus, no redundant description is made here.

[0194] In some possible implementation manners, the first device can send the device identification information to the second device by using the initial message. After determining that the second device receives the initial message, the first device can send the resource information to the second device by using the inventory message. When the second device receives the inventory message, the resource information can be parsed to determine the corresponding target resource information according to the device identification information.

[0195] In some cases, as shown in FIG. 13, for example, when the second device does not have a storage function or has a poor storage function, in order to avoid the inability to obtain the device identification information from the initial message, the first device can also carry the device identification information in the inventory message, so that the second device can directly perform the resource information operation according to the device identification information carried in the inventory message. The specific principle is similar to the related description of FIG. 9, and will not be described again.

[0196] In some possible implementations, in the current scenario, there can also be multiple target resource information configured in one time unit. For example, as shown in FIG. 14, one time unit includes two time domain resource information, which are time domain resource information with an identification sequence number of Slot#0 and time domain resource information with an identification sequence number of Slot#1. Therefore, the resource information here needs to include time domain resource information, that is, the initial message is used to send the time domain resource information, the frequency domain resource information, and the device identification to the second device.

[0197] In embodiment five and FIGS. 11-14, the multiple target resource information corresponding to one second device can be a third number of target resource information corresponding to the second device included in the resource information sent by the first device to the second device, so that after the second device receives the resource information, the corresponding target resource information can be determined according to the third number of target resource information and the order of the frequency domain index first and the time domain index second. The multiple target resource information corresponding to one second device can be an example in which one device corresponds to multiple frequency domain resource information, that is, the resource information sent by the first device to the second device needs to include a first number of frequency domain resource information corresponding to the second device, so that after the second device receives the resource information, the corresponding target resource information can be determined according to the first number of frequency domain resource information and the order of the frequency domain index first and the time domain index second.

[0198] In embodiment six, the process of sending the resource information and the device identification information to the second device in the scenario in which one second device corresponds to multiple target resources is introduced. The difference between embodiment five and embodiment six is that in embodiment five, the multiple target resource information corresponding to one second device can be multiple frequency domain resource information corresponding to one second device, and the second device needs to determine the resources in the order of the frequency domain resource index first and the time domain resource index second, while in embodiment six, the multiple target resource information corresponding to one second device can be multiple time domain resource information corresponding to one second device, and the second device needs to determine the resources in the order of the time domain resource index first and the frequency domain resource index second. In some cases, there can also be a case in which a certain second device corresponds to multiple time domain resource information and multiple frequency domain resource information.

[0199] In Embodiment Six, as shown in Figure 15, the first device can send the resource information and the device identification to the second device by using the initial message, and the initial message can be used as a start mark, when the second device receives the initial message, the resource information can be parsed to determine the corresponding target resource information according to the device identification information, it should be noted that the target resource information in the resource information here can only include the frequency domain resource information, and does not include the time domain resource information, the specific principle is the same as that in Embodiment Four, and details can be referred to the related description in Embodiment Four, and thus will not be repeated here.

[0200] In some possible implementation manners, as shown in Figure 16, the first device can send the resource information and the device identification to the second device by using the initial message, and the initial message can be used as a start mark, when the second device receives the initial message, the resource information can be parsed to determine the corresponding target resource information according to the device identification information,

[0201] It should be noted that the target resource information in the resource information here needs to include the time domain resource information, and the specific principle is the same as that in Embodiment Four, and details can be referred to the related description in Figure 8 in Embodiment Four, and thus will not be repeated here.

[0202] In some possible implementation manners, the first device can send the device identification information to the second device by using the initial message, and the initial message can be used as a start mark, when the second device receives the initial message, the resource information can be sent to the second device by using the inventory message, when the second device receives the inventory message, the resource information can be parsed to determine the corresponding target resource information according to the device identification information.

[0203] In some possible implementation manners, as shown in FIG. 17, for example, when the second device does not have a storage function or has a poor storage function, in order to avoid the device identifier information being unable to be acquired from the initial message, the first device can also carry the device identifier information in the inventory message, so that the second device can directly perform the resource information operation according to the device identifier information carried in the inventory message, and it needs to be noted that the target resource information in the resource information can only include the frequency domain resource information, and does not include the time domain resource information, that is, only the frequency domain resource information and the device identifier information are carried in the initial message. The specific principle is similar to the related description of FIG. 9, and no redundant description is made here.

[0204] In some possible implementation manners, in the current scenario, one time unit can also include multiple time domain resource information, for example, as shown in FIG. 18, for example, one time unit includes two time domain resource information, which are respectively time domain resource information with an identifier sequence number Slot#0 and time domain resource information with an identifier sequence number Slot#1, therefore, the resource information needs to include the time domain resource information, that is, the initial message is used to send the time domain resource information, the frequency domain resource information and the device identifier to the second device.

[0205] In the sixth embodiment and FIGS. 15 to 18, the third quantity of target resource information corresponding to one second device in the resource information sent by the first device to the second device can be the target resource information corresponding to the second device, so that after the second device receives the resource information, the corresponding target resource information can be determined according to the third quantity of target resource information and the time domain index sequence and the frequency domain index sequence. The second quantity of time domain resource information corresponding to one device can be taken as an example, that is, the second quantity of time domain resource information corresponding to the second device needs to be included in the resource information sent by the first device to the second device, so that after the second device receives the resource information, the corresponding target resource information can be determined according to the second quantity of time domain resource information and the time domain index sequence and the frequency domain index sequence.

[0206] It needs to be noted that the specific numbers appearing in FIGS. 7 to 18, for example, the resource information includes four frequency domain resource information and two time domain resource information, one second device corresponds to two frequency domain resource information and one second device corresponds to two time domain resource information, and the like are all examples for introduction, and a person skilled in the art can configure the quantity of frequency domain resource information and time domain resource information and the quantity of frequency domain resource information and time domain resource information corresponding to one second device according to actual needs, which is not limited here.

[0207] In Embodiment One to Embodiment Six, the data transmission method of the present application is introduced with the first device as the execution subject. In the following, another data transmission method provided by the present application is introduced with the second device as the execution subject, which is referred to as Embodiment Seven. The data transmission method introduced in Embodiment Seven is mainly different from the data transmission method introduced in Embodiment One to Embodiment Six in that the data transmission method introduced in Embodiment One to Embodiment Six mainly introduces the process of configuring resource information and sending resource information, and the data transmission method introduced in Embodiment Seven mainly introduces the process of receiving, by the second device, the resource information sent by the first device and determining, from the resource information, the target resource information corresponding to the target second device.

[0208] In order to make the technical solutions of the present application more clear and easy to understand, in the following, another data transmission method provided by the embodiments of the present application is introduced with the second device as the execution subject. As shown in FIG. 19, it can include:

[0209] S211: receiving the resource information sent by the first device.

[0210] The second device can receive the resource information sent by the first device.

[0211] The content of the resource information here is similar to that in step S801, and specific reference can be made to the introduction in step S801, which is not described here.

[0212] It should be noted that the second device receives the resource information sent by the first device, that is, if the configured resource information is the resource information required for data transmission by one second device, then the second device receives the resource information sent by the first device, and if the configured resource information is the resource information required for data transmission by multiple second devices, then each second device in the multiple second devices needs to receive the resource information sent by the first device.

[0213] S212: determining, from the resource information, the target resource information corresponding to the target second device.

[0214] Since the resource information can be the resource of multiple second devices configured by the first device, after receiving the resource information, the second device needs to determine the target resource information corresponding to itself (i.e., the target second device) from the resource information.

[0215] In some possible implementation manners, when the second device determines multiple target resources, it can select one target resource to send data, or send data on the determined multiple target resources. The data can be MSG1, MSG3 and data on PDRCH (physical device to reader channel).

[0216] In some possible implementation manners, the second device can determine the target resource information corresponding to the target second device identifier from the resource information in ascending order of the frequency domain resource index or in descending order of the frequency domain resource index, and / or determine the target resource information corresponding to the target second device identifier from the resource information in ascending order of the time domain resource index or in descending order of the time domain resource index, where the ascending order of the frequency domain resource index refers to ascending in the order of the identification sequence number of the frequency domain resource information from small to large, for example, {#0, #1, #2, #3}, the descending order of the frequency domain resource index refers to descending in the order of the identification sequence number of the frequency domain resource information from large to small, for example, {#3, #2, #1, #0}, (the ascending order of the frequency domain resource can be from low frequency to high frequency, or from high frequency to low frequency), the ascending order of the time domain resource index refers to ascending in the order of the identification sequence number of the time domain resource information from small to large, for example, {slot#0, slot#1, slot#2, slot#3}, and the descending order of the time domain resource index refers to descending in the order of the identification sequence number of the time domain resource information from large to small, for example, {slot#3, slot#2, slot#1, slot#0}.

[0217] Specifically, the target resource information of the target second device can be determined in the following implementation manners.

[0218] The first implementation manner can first determine the target resource information of the target second device in ascending order of the frequency domain resource index and then in ascending order of the time domain resource index, that is, in this case, the frequency domain resource information and the time domain resource information of the target second device can be first determined in ascending order of the frequency domain resource index, when the frequency domain resource information corresponding to the time domain resource information is allocated, the time domain index is increased in ascending order of the time domain resource index, and then the corresponding frequency domain resource is determined in ascending order of the frequency domain resource index and the corresponding time domain resource information is determined in ascending order of the time domain resource index. For example, the frequency domain resource information corresponding to the identification sequence number #0 of the first configured resource information of the second device can be determined, and the time domain resource information corresponding to the identification sequence number slot#0 of the second device can be determined in the case of determining the frequency domain resource information.

[0219] The frequency domain resource information corresponding to the identification sequence number #1 of the second configured resource information of the second device can be determined in ascending order of the frequency domain resource index, and the time domain resource information corresponding to the identification sequence number slot#0 of the second device can be determined in the case of determining the frequency domain resource information.

[0220] For example, when determining the frequency domain resource corresponding to the second device of the fifth configuration resource information, the frequency domain resource information corresponding to the first time domain resource information is allocated, the time domain index #1 is increased in the increasing order of the time domain resource index, the time domain resource information corresponding to the identification sequence #0 is determined again in the increasing order of the time domain resource index, and the frequency domain resource information corresponding to the identification sequence #1 is determined in the increasing order of the frequency domain resource index.

[0221] The second implementation manner can determine the target resource information of the target second device in the increasing order of the frequency domain resource index and in the decreasing order of the time domain resource index.

[0222] The third implementation manner can determine the target resource information of the target second device in the decreasing order of the frequency domain resource index and in the decreasing order of the time domain resource index.

[0223] The fourth implementation manner can determine the target resource information of the target second device in the decreasing order of the frequency domain resource index and in the increasing order of the time domain resource index.

[0224] The fifth implementation manner can determine the target resource information of the target second device in the increasing order of the time domain resource index and in the increasing order of the frequency domain resource index.

[0225] For example, the time domain resource information corresponding to the identification sequence slot#0 of the first configuration resource information can be determined, and the frequency domain resource information corresponding to the identification sequence #0 of the second device can be determined in the case of determining the time domain resource information.

[0226] The time domain resource information corresponding to the identification sequence slot#1 of the second configuration resource information can be determined in the increasing order of the time domain resource index, and the frequency domain resource information corresponding to the identification sequence #0 of the second device can be determined in the case of determining the time domain resource information.

[0227] For example, when determining the time domain resource corresponding to the second device of the third configuration resource information, the time domain resource information corresponding to the first frequency domain resource information is allocated, the frequency domain index #1 is increased in the increasing order of the frequency domain resource index, the time domain resource information corresponding to the identification sequence slot#0 of the third configuration resource information of the second device is determined again in the increasing order of the time domain resource index, and the frequency domain resource information corresponding to the identification sequence #1 is determined in the increasing order of the frequency domain resource index.

[0228] The sixth implementation manner can determine the target resource information of the target second device in the increasing order of the time domain resource index and in the decreasing order of the frequency domain resource index.

[0229] The seventh implementation manner can first determine the target resource information of the target second device in descending order of the time domain resource index, and then in descending order of the frequency domain resource index.

[0230] The eighth implementation manner can first determine the target resource information of the target second device in descending order of the time domain resource index, and then in ascending order of the frequency domain resource index.

[0231] In some possible implementation manners, the second device can further receive device identification information, where the device identification information can include a device identification and / or a configuration order of the device identification, and the second device can further determine one or more target resource information in the resource information according to the configuration order of the device identification. That is, the second device maps to the target resource according to the above eight implementation manners according to the configuration order of the device identification.

[0232] In some possible implementation manners, the resource information can further include a third quantity of target resource information corresponding to the second device, where a quantity of frequency domain resource information corresponding to the second device is a first quantity, and a quantity of time domain resource information corresponding to the second device is a second quantity, and the first quantity of frequency domain resource information of the target second device can be determined according to the configuration order of the device identification and / or the frequency domain resource index order. That is, the second device maps to the target resource according to the above eight implementation manners according to the configuration order of the device identification, and the first quantity or the second quantity or the third quantity. If the first device configures the third quantity, that is, the quantity of target resources corresponding to the second device, the second device can map the device itself to the corresponding target resource information according to the above eight implementation manners (that is, determine the target resource information of the target second device), where the standard can define a way for resource matching.

[0233] If the first device configures the first quantity, the target resource information of the target second device can be determined by default according to the frequency domain index order and then the time domain index order, that is, by using the first to fourth manners. If the second quantity is configured, the target resource information of the target second device is determined by default according to the time domain resource index order and then the frequency domain resource index order, that is, by using the fifth to eighth manners. The first quantity and the second quantity can be configured to the second device at the same time, and in this case, the second device determines the target resource corresponding to the target second device according to the first quantity and the second quantity and the corresponding target resource information determination method (the first quantity corresponds to the first to fourth manners, and the second quantity corresponds to the fifth to eighth manners).

[0234] The first quantity and the second quantity can be configured to the second device at the same time, and in this case, the second device determines the target resource corresponding to the target second device according to the first quantity and the second quantity and the corresponding target resource information determination method (the first quantity corresponds to the first to fourth manners, and the second quantity corresponds to the fifth to eighth manners).

[0235] S213: transmitting data through the target resource information.

[0236] After the second device determines the target resource information corresponding to the target second device from the resource information, the second device can trigger random access or non-contention random access, and transmit data to the first device by using the target resource information, wherein the transmitted data can be MSG1 message or data in uplink message (physical device to reader channel, PDRCH).

[0237] The second device can receive the resource information sent by the first device, and then determine the target resource information corresponding to the target second device from the resource information, wherein the second device can correspond to one or more target resource information, and the target resource information can include frequency domain resource information and / or time domain resource information. Finally, the second device can transmit data to the first device through the target resource information. Since the first device configures one or more target resource information corresponding to each second device, the second device can determine the target resource information corresponding to itself after receiving the resource information, so that the second device can obtain the resource information required for data transmission.

[0238] In the above embodiment seven, the process of the second device receiving the resource information sent by the first device and determining the target resource information corresponding to the target second device from the resource information is briefly introduced. In the following, the process of determining the target resource information corresponding to the target second device from the resource information in different scenarios such as one second device corresponding to one target resource information and one second device corresponding to multiple target resource information (the target resource information can be time domain resource information and / or frequency domain resource information) is introduced.

[0239] Firstly, how to determine the target resource information corresponding to the target second device from the resource information in the scenario of one second device corresponding to one target resource information needs to be explained, that is, the target resource information here can be regarded as a resource block, one target resource information can be a frequency domain resource information, a time domain resource information, or a frequency domain resource information and a frequency domain resource information. This scenario can be referred to as embodiment eight, which includes:

[0240] The second device can determine the target resource information corresponding to the target second device from the resource information according to the target second device identifier, the configuration order of the device identifier, the resource index order, and the number of frequency domain resource multiplexing (FDM).

[0241] Exemplarily, taking the target resource information of the target second device as an example, which is determined in the ascending order of the frequency domain resource index and then in the ascending order of the time domain resource index in the order of the resource index, the specific formula for determining the target resource information corresponding to the target second device from the resource information according to the target second device identifier, the configuration order of the device identifier and the number of frequency domain resource multiplexing (FDM) can be shown as (1) and (2):

[0242] T = floor (target second device identifier in the configuration order of the device identifier / FDM number) (1)

[0243] F = modulo (target second device identifier in the configuration order of the device identifier / FDM number) (2)

[0244] Wherein, the formula in (1) is used to determine the identifier T of the target second device, and the formula in (2) is used to determine the identifier F of the time domain resource information of the target second device. It should be noted that the position of the target second device identifier in the configuration order of the device identifier is the position of the first second device identifier in the configuration order of the device identifier, which is 0, the position of the second second device identifier in the configuration order of the device identifier is 1, and so on.

[0245] Exemplarily, taking the configuration order of the device identifier as {deviceID#0, deviceID#1, deviceID#2, deviceID#3} as an example, the value of the position of deviceID#0 in the configuration order of the device identifier is 0, the value of the position of deviceID#1 in the configuration order of the device identifier is 1, the value of the position of deviceID#2 in the configuration order of the device identifier is 2, and the value of the position of deviceID#3 in the configuration order of the device identifier is 3. For example, the configuration order of the device identifier is {deviceID#1, deviceID#2, deviceID#3, deviceID#4}, the value of the position of deviceID#1 in the configuration order of the device identifier is also 0, where n is the device ID number, for example, the device ID number of deviceID#0 is 0, and the device ID number of deviceID#1 is 1.

[0246] For example, the number of FDMs is 4, the frequency domain resource information is {#0, #1, #2, #3}, the time domain resource information is {slot#0, slot#1, slot#2, slot#3}, and the configuration order of the device identifier is {deviceID#0, deviceID#1, deviceID#2, deviceID#3}. The second device with device ID #0 is the first in the configuration order of the device identifier. Substituting formula (1) and formula (2) into formula (1) and formula (2), the value of the position of the target second device identifier in the configuration order of the device identifier is 1. The frequency domain resource information corresponding to the second device identifier is #0, and the time domain resource information corresponding to the second device identifier is slot#0.

[0247] The above embodiment eight introduces how to determine the target resource information corresponding to the target second device from the resource information in the scenario where one second device corresponds to one target resource information. Here, example nine can be introduced, which introduces how to determine the target resource information corresponding to the target second device from the resource information in the scenario where one second device corresponds to multiple target resource information, i.e., the first device is configured with a third number or a second number. Embodiment nine can include:

[0248] In some possible implementations, the starting frequency domain resource information and the starting time domain resource information corresponding to the target second device can be determined first, where the starting frequency domain resource information is the first frequency domain resource information corresponding to the target second device. Then, other frequency domain resource information in the frequency domain resource information is determined according to the starting frequency domain resource information, and other frequency domain resource information in the multiple time domain resource information corresponding to the target second device is determined according to the starting time domain resource information.

[0249] For example, the target resource information of the target second device is determined in the order of the increasing order of the time-frequency domain resource index and the increasing order of the frequency domain resource index. The second device can determine the product of the position of the target second device identifier in the configuration order of the device identifier and the number of time domain resource information corresponding to each second device. The ratio of the product to the number of frequency domain resource multiplexing is rounded down to determine the starting time domain resource information corresponding to the target second device.

[0250] Specifically, it can be shown as formula (3):

[0251] T start=floor(target second device identifier in the configuration order of device identifiers *N / FDM number) or target second device identifier in the configuration order of device identifiers *N (3), the position of the device identifier in the configuration order of the device identifier starts from index 0, that is, the first device corresponds to index 0, the second device corresponds to index 1, and so on, wherein T start is the starting time domain resource information, and N here is the number of target resource information corresponding to a second device.

[0252] The second device can take the modulus of the ratio of the position of the target second device identifier in the configuration order of the device identifier and the frequency domain resource multiplexing number to determine the starting frequency domain resource information corresponding to the target second device.

[0253] Specifically, it can be as shown in formula (4):

[0254] F start=modulo(target second device identifier in the configuration order of device identifiers / FDM number) or F start=target second device identifier in the configuration order of device identifiers modulo FDM number (4), wherein F start is the starting frequency domain resource information.

[0255] For example, here is an example of one second device corresponding to multiple time domain resource information and one second device corresponding to one frequency domain resource information, so the starting frequency domain resource information can be used as the frequency domain resource information.

[0256] According to the starting time domain resource information, the other time domain resource information in the multiple time domain resource information corresponding to the target second device can be determined as:

[0257] According to the starting time domain resource information of the target second device, the other time domain resource information of the target second device is determined according to the time domain resource index order and the number of time domain resource information, wherein the index order of the time domain resource is the increasing order of the time domain resource index or the decreasing order of the time domain resource index.

[0258] Specifically, the sum of the starting time domain resource information and the number index of the target time domain resource information can be determined, and then the other time domain resource information is determined according to the ratio of the sum of the starting time domain resource information and the number index of the target time domain resource information and the number of time domain resource information.

[0259] Specifically, it can be as shown in formula (5):

[0260] T(i) = modulo((Tstart+i) / N)] (5) Wherein, T(i) can include starting time domain resource information and other time domain resource information, Tstart is starting time domain resource information, i here is the number index of target frequency domain resource information, used to represent the second device corresponding to the first resource information. N is the number of target resource information corresponding to a second device, for example, i takes value [0, …, n-1],

[0261] Here i is the second device corresponding to a certain time domain information in its corresponding all time domain resource information of the first, it is need to point out that, i for 0 when indicating the first time domain resource, i for 1 when indicating the second time domain resource, so on and so forth, i for N-1 when corresponding the Nth time domain resource.

[0262] For example, if the time domain resource information identifier configured by the first device is {slot#0, slot#1, slot#2, slot#3} respectively, the target resource quantity corresponding to the second device is 2, the identifier of the two time domain resource information corresponding to the first second device is {slot#0, slot#1} respectively, then the time domain resource information corresponding to slot#0 is the first time domain resource information of the number index of two time domain resource information for 0, then the time domain resource information corresponding to slot#1 is the second time domain resource information of the number index of two time domain resource information for 1, the value rule of i here can be as follows:

[0263] The i value corresponding to the first time domain resource information of the second device is 0, the i value corresponding to the second time domain resource information of the second device needs to be +1 based on the i value corresponding to the first time domain resource information, the i value is 1, the i value corresponding to the third time domain resource information needs to be +1 based on the i value corresponding to the second time domain resource information, the i value is 2, and so on. For example, if the time domain resource information identifier configured by the first device is {slot#1, slot#2, slot#3, slot4} respectively, the identifier of the two time domain resource information corresponding to the second device is {slot#1, slot#2} respectively, then the time domain resource information corresponding to slot#1 is the first time domain resource information, and the i value corresponding to slot#1 is 0.

[0264] Exemplarily, as shown in FIG. 15, taking the frequency domain resource information as {#0, #1, #2, #3}, the time domain resource as {slot#0, slot#1}, and the configuration order of the device identifier as {deviceID#0, deviceID#1, deviceID#2, deviceID#3}, one second device corresponding to two time domain resource information is taken as an example for introduction. For example, the first time domain resource information corresponding to the first configured resource information of the second device (i.e., the second device with deviceID #0) is determined according to formula (3), that is, the starting time domain resource information is the time domain resource information identified as slot#0, and the number index i of the target time domain resource information corresponding to the starting time domain resource information is 0. Then the second time domain resource information corresponding to the second device can be determined according to formula (5), at this time, the value of the number index i of the target time domain resource information is increased by 1, i.e., i=1, and formula (5) is brought in to determine that the second time domain resource information corresponding to the second device is the time domain resource information identified as slot#1.

[0265] In some possible implementation manners, the application can also take the floor of the ratio of the position of the target second device identifier in the configuration order of the device identifier to the frequency domain resource multiplexing number, determine the product of the result obtained by the floor and the number of time domain resource information, and then determine the target resource information corresponding to the target second device according to the sum of the product and the number index of the target time domain resource information. Here, the principle is similar to formula (6).

[0266] In some possible implementation manners, the second device can also directly determine the frequency domain resource information and the time domain resource information.

[0267] Exemplarily, the second device can take the floor of the ratio of the position of the target second device identifier in the configuration order of the device identifier to the frequency domain resource multiplexing number, determine the product of the result obtained by the floor and the number of target resource information, and determine the target resource information corresponding to the target second device according to the sum of the product and the number index of the target time domain resource information.

[0268] Specifically, it can be shown in formula (6):

[0269] T(i)=i+N*floor(target second device identifier in the configuration order of the device identifier / FDM number)(6)

[0270] Here, formula (6) has other other schemes, and the specific formula can be as follows:

[0271] T(i)=modulo((floor(target second device identifier in the configuration order of the device identifier*N / FDM number)+i) / N)or i+N*target second device identifier in the configuration order of the device identifier

[0272] wherein, here, i is the index of the quantity of target time domain resource information, and here, N is the quantity of target resource information corresponding to one second device.

[0273] The first device can determine the target frequency domain resource information corresponding to the target second device according to the result of the downward rounding.

[0274] Specifically, it can be shown as formula (7):

[0275] F(i) = modulo(target second device identifier in the configuration order of device identifier / FDM number) (7)

[0276] For example, as shown in FIG. 15, taking the FDM number as 4, the frequency domain resource information as {#0, #1, #2, #3}, the time domain resource as {slot#0, slot#1}, the configuration order of the device identifier as {deviceID#0, deviceID#1, deviceID#2, deviceID#3}, and one second device corresponding to two time domain resource information as an example, it is introduced that, for example, the first time domain resource information corresponding to the second device of the first configuration resource information (i.e., the second device with deviceID #0) can be determined according to formula (6), at this time, the index i of the quantity of target time domain resource information is 0, i.e., the first time domain resource corresponding to the second device is determined as the time domain resource information with identifier slot#0 by bringing formula (6). According to formula (7), the frequency domain resource corresponding to the second device can be determined as the frequency domain resource information with identifier #0.

[0277] For another example, the second time domain resource information corresponding to the second device of the first configuration resource information (i.e., the second device with deviceID #0) can be determined according to formula (6), at this time, the index i of the quantity of target time domain resource information needs to be increased by 1, i.e., i = 1, i.e., the second time domain resource corresponding to the second device is determined as the time domain resource information with identifier slot#1 by bringing formula (6). According to formula (7), the frequency domain resource corresponding to the second device can be determined as the frequency domain resource information with identifier #0.

[0278] The following introduces embodiment ten, in which, in the scenario in which one second device corresponds to multiple target resources, i.e., the first device is configured with the third quantity or the first quantity, how to determine the target resource information corresponding to the target second device from the resource information is introduced, which can be referred to as embodiment ten, including:

[0279] In some possible implementation manners, the second device can first determine the starting frequency domain resource information corresponding to the target second device and the starting time domain resource information corresponding to the target second device, where the starting frequency domain resource information is the first frequency domain resource information corresponding to the target second device, and the starting time domain resource information is the first time domain resource information corresponding to the target second device, then determine other frequency domain resource information in the multiple frequency domain resource information corresponding to the target second device according to the starting frequency domain resource information, and determine other time domain resource information in the time domain resource information corresponding to the target second device according to the starting time domain resource information.

[0280] For example, the target resource information of the target second device is determined in the order of increasing order of frequency domain resource index and then increasing order of time domain resource index. The second device can determine the product of the position of the target second device identifier in the configuration order of the device identifier and the number of frequency domain resource information corresponding to each second device, take the remainder of the ratio of the product and the frequency domain resource multiplexing number, and determine the starting frequency domain resource information corresponding to the target second device.

[0281] Specifically, it can be shown in formula (8):

[0282] F start=modulo{(target second device identifier in the configuration order of the device identifier in the position*N) / FDM number}(8) where F start is the starting frequency domain resource information.

[0283] The second device can determine the product of the position of the target second device identifier in the configuration order of the device identifier and the number of frequency domain resource information corresponding to each second device, take the floor of the ratio of the product and the frequency domain resource multiplexing number, and determine the starting time domain resource information corresponding to the target second device. Specifically, it can be shown in formula (9):

[0284] T start=floor(target second device identifier in the configuration order of the device identifier in the position*N / FDM number)(9), where T start is the starting time domain resource information, and N in formula (8) and (9) is the number of target resource information corresponding to one second device.

[0285] Determining other frequency domain resource information in the multiple frequency domain resource information corresponding to the target second device according to the starting frequency domain resource information can be specifically:

[0286] According to the starting frequency domain resource information of the target second device, other frequency domain resource information of the target second device is determined according to the order of frequency domain resource index and the number of frequency domain resource information, where the order of frequency domain resource index is increasing order of frequency domain resource index or decreasing order of frequency domain resource index.

[0287] The specific formula is shown in 10:

[0288] F(i) = modulo((F start+i) / FDM number) (10), where F(i) can include the start frequency domain resource information and other frequency domain resource information, F start is the identification of the start frequency domain resource, and i here is the number index of the target frequency domain resource information, used to represent the corresponding frequency domain resource information of the second device.

[0289] For example, the value of i is [0, …, N-1], i is the corresponding frequency domain resource information of the second device in all corresponding frequency domain resource information. For example, if the identification of the frequency domain resource information configured by the first device is {#0, #1, #2, #3}, and the identification of the two frequency domain resource information corresponding to the second device is {#0, #1}, the frequency domain resource information corresponding to #0 is the first frequency domain resource information of the two frequency domain resource information, and the value of i is 0. The frequency domain resource information corresponding to #1 is the second frequency domain resource information of the two frequency domain resource information, and the value of i is 1.

[0290] The value of i here can be as follows:

[0291] The value of i corresponding to the first frequency domain resource information of the second device is 0, the value of i corresponding to the second frequency domain resource information of the second device needs to be +1 based on the value of i corresponding to the first frequency domain resource information, and the value of i is 1. The value of i corresponding to the third frequency domain resource information needs to be +1 based on the value of i corresponding to the second frequency domain resource information, and the value of i is 2. Similarly.

[0292] For example, if the identification of the frequency domain resource information configured by the first device is {#1, #2, #3, #4}, and the identification of the two frequency domain resource information corresponding to the second device is {#1, #2}, the frequency domain resource information corresponding to #1 is the first frequency domain resource information in the multiple frequency domain resource information, and the value of i is 0. The frequency domain resource information corresponding to #2 is the second frequency domain resource information, and the value of i is 1.

[0293] For example, as shown in FIG. 11, taking the frequency domain resource information as {#0, #1, #2, #3}, the time domain resource information as {slot#0, slot#1}, and the configuration order of the device identifier as {deviceID#0, deviceID#1, deviceID#2, deviceID#3}, one second device corresponding to two frequency domain resource information is taken as an example for description. For example, the first frequency domain resource information corresponding to the second device (i.e., the second device with deviceID #0) of the first configuration resource information is determined according to formula (8), i.e., the starting frequency domain resource information is the frequency domain resource information with identifier #0, and the number index i of the target frequency domain resource information corresponding to the starting frequency domain resource information is 0. Then, the second frequency domain resource information corresponding to the second device can be determined according to formula (10), at this time, the value of the number index i of the target frequency domain resource information is increased by 1, i.e., i=1, and formula (10) is brought in, and it can be determined that the second frequency domain resource information corresponding to the second device is the frequency domain resource information with identifier #1.

[0294] For another example, as shown in FIG. 20, taking the frequency domain resource information as {#0, #1, #2, #3}, the time domain resource information as {slot#0, slot#1}, and the configuration order of the device identifier as {deviceID#0, deviceID#1, deviceID#2, deviceID#3}, one second device corresponding to three frequency domain resource information is taken as an example for description. If it is necessary to determine each frequency domain resource information of the second device of the second configuration resource information, the first frequency domain resource information corresponding to the second device (i.e., the second device with deviceID #1) of the second configuration resource information can be determined according to formula (8), i.e., the starting frequency domain resource information is the frequency domain resource information with identifier #3, and the number index i of the target frequency domain resource information corresponding to the starting frequency domain resource information is 0. The first time domain resource information corresponding to the device is determined according to formula (9), i.e., the starting time domain resource information is the time domain resource information with identifier slot#0.

[0295] At this time, other frequency domain resource information and other starting time domain resource can be determined according to the starting frequency domain resource information and the starting time domain resource information according to the third number or the first number according to the frequency domain resource index order and then the time domain resource index order, and it should be noted that the frequency domain resource index order and the time domain resource index order are taken as an example of increasing.

[0296] For example, the second frequency domain resource information corresponding to the second device can be determined according to the starting frequency domain resource information of the second device according to formula (10). At this time, it can be seen from Figure 20 that the frequency domain resource index is flipped, and the value of i is increased by 1 based on the value of i corresponding to the starting frequency domain resource information. According to formula (10), the corresponding second frequency domain resource information is identified as the frequency domain resource information #0.

[0297] Optionally, then, according to formula (6), the next, that is, the second time domain resource information is determined according to the starting time domain resource information of the second device according to the frequency domain resource index sequence. Here, i in formula (6) is the quantity index of the target time domain resource information.

[0298] The value of the quantity index of the target frequency domain resource information is increased by 1, which is brought into formula (6), and the second time domain resource information corresponding to the second device is determined as the time domain resource information identified as slot #1.

[0299] According to the similar principle described above, the frequency domain resource information and the corresponding time domain resource information of the second device corresponding to the second configuration resource information can be determined.

[0300] In some possible implementation manners, the second device can also determine a first sum of the product of the quantity of the target resource information and the position of the target second device identifier in the configuration sequence of the device identifier and the quantity index of the target frequency domain resource information, and determine the target resource information corresponding to the target second device according to the remainder obtained by dividing the first sum by the frequency domain resource multiplexing number. Here, the principle is similar to that of formula (12).

[0301] In some possible implementation manners, the second device can also directly determine the frequency domain resource information and the time domain resource information.

[0302] For example, the first device can determine a second sum of the product of the quantity of the frequency domain resource information and the position of the target second device identifier in the configuration sequence of the device identifier and the quantity index of the target frequency domain resource information, and then determine the time domain resource information corresponding to the target second device according to the integer part obtained by dividing the second sum by the frequency domain resource multiplexing number.

[0303] Specifically, it can be shown in formula (11):

[0304] T(i) = floor((i + N * target second device identifier in the configuration sequence of the device identifier) / FDM number) (11), where T(i) is the identifier of the time domain resource information, i is the quantity index of the target frequency domain resource information, and N is the quantity of the target resource information corresponding to one second device.

[0305] The first device can determine the frequency domain resource information corresponding to the target second device according to the modulo operation of the ratio of the second and the number of frequency domain resource multiplexing.

[0306] Specifically, it can be shown as formula (12):

[0307] F(i) = modulo((i + N * target second device identifier in the configuration order of device identifier) / FDM number) (12), where i is the number index of the target frequency domain resource information, N is the number of target resource information corresponding to one second device, and F(i) is the identifier of the frequency domain resource information.

[0308] For example, as shown in FIG. 11, the number of FDM is 4, the frequency domain resource information is {#0, #1, #2, #3}, the time domain resource is {slot#0, slot#1}, the configuration order of the device identifier is {deviceID#0, deviceID#1, deviceID#2, deviceID#3}, and one second device corresponds to two frequency domain resource information. For example, the first frequency domain resource information corresponding to the first configured resource information of the second device (i.e., the second device with deviceID #0) can be determined according to formula (12), and the number index i of the target time domain resource information is 0, i.e., the first frequency domain resource corresponding to the second device is determined by formula (12) as the frequency domain resource information with identifier #0. According to formula (11), the time domain resource corresponding to the second device is the time domain resource information with identifier slot#0.
