Description

Data transmission method, device and storage medium

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a data transmission method, an apparatus, and a storage medium.

Background

In the New Radio technology (NR) Release 15 version of 5G, the terminal device may have three states, namely an idle (idle) state, an inactive (inactive) state and an active (active) state.

When the terminal device does not receive and transmit data, the base station can indicate the terminal device to enter an inactive state. When the terminal device is in an inactive state or idle, the terminal device may not need to monitor a Physical Downlink Control Channel (PDCCH), and may only perform reference signal detection, cell reselection, paging (english may be referred to as paging), system message monitoring, and the like.

Different from the idle state of the terminal device, when the terminal device is in the inactive state, the base station and the terminal device can store the context of the terminal device, and when data needs to be received and sent, the terminal device can quickly restore Radio Resource Control (RRC) connection through a random access process to enter the active state without performing processes such as security mode activation, capability reporting, information configuration and the like again, so that the signaling interaction process can be reduced, the signaling overhead is reduced, and the power consumption of the terminal device is reduced.

The Release 16 version does not support the terminal device to transmit the user plane data in the inactive state, if the terminal device has the user plane data to be transmitted, the terminal device needs to enter the active state through random access first, and then the terminal device transmits the data in the active state. The terminal device initiates a random access process, which increases power consumption of the terminal device and increases data transmission delay. In an application scenario where the terminal device needs to upload data frequently, the power consumption of the terminal device will be increased due to the frequent initiation of the random access process by the terminal device.

The system 100 as shown in fig. 1 comprises a network device 101 and a terminal device 102. It should be understood that, in the embodiment of the present invention, the number of network devices and the number of terminal devices in the system architecture are not limited, and the system architecture to which the embodiment of the present invention is applied may further include other devices, such as a core network device, a wireless relay device, a wireless backhaul device, and the like, besides the network devices and the terminal devices, and the embodiment of the present invention is also not limited. In addition, the network device in the embodiment of the present invention may integrate all functions into one independent physical device, or may distribute the functions over multiple independent physical devices, which is not limited in this embodiment of the present invention. In addition, the terminal device in the embodiment of the present invention may be connected to the network device in a wireless manner.

The technical scheme of the embodiment of the invention can be applied to various communication systems, such as: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) System, a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) Communication System, a 5G Communication System, and the like.

The following is a description of terms and related technologies related to embodiments of the present invention.

Terminal devices include devices that provide voice and/or data connectivity to a user and may include, for example, handheld devices having wireless connection capabilities or processing devices connected to wireless modems. The terminal device may communicate with a core network via a Radio Access Network (RAN), exchanging voice and/or data with the RAN. The terminal device may include a User Equipment (UE), a wireless terminal device, a mobile terminal device, a device-to-device communication (D2D) terminal device, a V2X terminal device, a machine-to-machine/machine-type communication (M2M/MTC) terminal device, an internet of things (IoT) terminal device, a subscriber unit (subscriber unit), a subscriber station (subscriber state), a mobile station (mobile state), a remote station (remote state), an access point (access point, AP), a remote terminal (remote terminal), an access terminal (access terminal), a user terminal (user terminal), a user agent (user agent), or a user equipment (user device), etc. For example, mobile telephones (or so-called "cellular" telephones), computers with mobile terminal equipment, portable, pocket, hand-held, computer-included mobile devices, and the like may be included. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. Also included are constrained devices, such as devices that consume less power, or devices that have limited storage capabilities, or devices that have limited computing capabilities, etc. Examples of information sensing devices include bar codes, Radio Frequency Identification (RFID), sensors, Global Positioning Systems (GPS), laser scanners, and the like.

Network devices, including, for example, Access Network (AN) devices, such as base stations (e.g., access points), may refer to devices in AN access network that communicate with wireless terminal devices over one or more cells over AN air interface. The base station may be configured to interconvert received air frames and Internet Protocol (IP) packets as a router between the terminal device and the rest of the access network, which may include an IP network. The RSU may be a fixed infrastructure entity supporting the V2X application and may exchange messages with other entities supporting the V2X application. The network device may also coordinate attribute management for the air interface. For example, the network device may include an evolved Node B (NodeB) or eNB or e-NodeB in an LTE system or an LTE-a (long term evolution-advanced), or may also include a next generation Node B (gNB) in a 5th generation mobile communication technology (5G) New Radio (NR) system, or may also include a Centralized Unit (CU) and a Distributed Unit (DU) in a Cloud access network (Cloud RAN) system, and the embodiments of the present invention are not limited thereto.

The terminal equipment in the embodiment of the invention can have three states, namely an inactive state, an active state and an idle state. When the terminal equipment is in an inactive state, the base station and the terminal equipment can store the context of the terminal equipment, when data needs to be received and sent, the terminal equipment can quickly recover RRC connection through a random access process to enter the active state, and processes such as security mode activation, capability reporting, information configuration and the like do not need to be carried out again, so that the signaling interaction process can be reduced, the signaling overhead is reduced, and the power consumption of the terminal equipment is reduced. Several random access procedures for the terminal device are described below. The random access procedure of LTE and the conventional random access procedure of NR can be classified into two types, contention random access and non-contention random access. The contention random access procedure may include two procedures, which are 4-step RACH (4-step RACH) and 2-step RACH (2-step RACH), and the specific content is referred to as a related protocol, and is not described herein again.

With the development of the internet of things, an application scenario exists, in which a terminal device needs to transmit uplink data of a certain size to a network device, for example, a water meter may need to periodically report parameters of the water meter to a server, and a sports bracelet needs to periodically report collected heartbeat data of a user to the network device. The size of the upstream data may be hundreds of bits, for example, 600 bits or 800 bits, or even 1000 bits or thousands of bits. If the scheme in the prior art is adopted, the terminal device needs to access the network device through a random access process, and then data is transmitted in an active state. The data amount may be several hundred bits or several thousand bits, and if the terminal device frequently performs the random access process, the terminal device may consume a large amount of power. Based on this, the scheme provided in the embodiment of the present invention can enable the terminal device to transmit the user plane data in an inactive state, so as to alleviate the power consumption problem of the terminal device.

On the other hand, since the size of the data that the terminal device needs to report to the network device may not be fixed, if the number of bits that can be carried in the random access request MsgA is set to a fixed value in the standard, for example, it is specified that 1000 bits of user plane data can be carried through MsgA, when the terminal device needs to transmit a smaller amount of data, for example, 50 bits, in this case, the terminal device will also transmit the 50 bits of data through the resource block that can carry 1000 bits, which obviously causes a large amount of waste of resources. When the terminal device needs to transmit a large amount of data, such as 1100 bits, under such a condition, the terminal device finds that one MsgA cannot load the 1100 bits and can only carry 1000 bits at most, so that the terminal device enters an active state through a random access process and then transmits data to the network device in the active state, thereby causing a power consumption problem of the terminal device. In view of the above problem, an embodiment of the present invention provides a scheme that enables a terminal device to select a resource block with an appropriate size according to a data amount of data to be transmitted, and the following describes an implementation of the present invention in detail.

Fig. 2 is a schematic flow chart of a data transmission method according to an embodiment of the present invention, as shown in fig. 2, the method includes:

step 200, determining a target RO, a target leader sequence and a target PO group according to the data volume of data to be transmitted and the mapping relation among the time-frequency resource RO of the PRACH, the leader sequence and the time-frequency resource PO group of the PUSCH;

in step 200, in one possible embodiment, the number of bits used to carry data in the target PO group satisfies the data to be transmitted.

In step 200, in a possible embodiment, when selecting the target RO, the target preamble sequence and the target PO group having a mapping relationship, in addition to the requirement that the number of bits used for carrying data in the target PO group satisfies the data amount of the data to be transmitted, the terminal device may also consider other rules such as channel conditions, for example, whether Reference Signal Receiving Power (RSRP), Signal to Interference plus Noise Ratio (SINR) and the like satisfy requirements.

Step 201, transmitting the target preamble sequence on the target RO, and transmitting the data to be transmitted on the resource block in the target PO group; the number of bits used for carrying data in the target PO group meets the data volume of the data to be transmitted;

In step 201, the terminal device sends MsgA in inactive state. And transmitting the data to be transmitted through the time-frequency resource corresponding to the PO in the MsgA. The data to be transmitted may be user plane data. On one hand, when the terminal device sends MsgA in an inactive state, the data to be transmitted can be transmitted through the time-frequency resource corresponding to the PO group, so that the time delay of data transmission can be shortened compared with a scheme that the terminal device transmits data after the random access is successful.

On the other hand, when the terminal device transmits data to be transmitted in the inactive state, even if the MsgB is subsequently received, the MsgB does not need to enter the active state, and can be continuously maintained in the inactive state, so that the electric quantity of the terminal device can be saved, and the power consumption problem of the terminal device can be alleviated.

Thirdly, different ROs can correspond to different PO groups, and the number of bits used for carrying data in two PO groups can be different, so that the terminal device can select a suitable target PO group to transmit the data to be transmitted according to the data amount of the data to be transmitted. It can be seen that, the embodiment of the present invention provides more flexibility for the terminal device to perform data transmission in the inactive state, and can also support the terminal device to perform data block transmission in various sizes in the inactive state, so as to meet different service requirements of the terminal device, and the embodiment of the present invention can also improve the utilization efficiency of network resources.

According to the data transmission method provided by the embodiment of the invention, the network equipment can support various transmission blocks in a non-connection state in the random access process, and the terminal can flexibly select uplink transmission resources in the MSGA according to the size of data service and channel conditions; more flexibility is provided for the random access resource allocation of the network equipment, the utilization efficiency of the network resources is improved, and meanwhile, the terminal equipment supports various data transmission quantities (from dozens of bits to thousands of bits) in a non-connection state, and different service requirements of the terminal are met.

Optionally, on the basis of the above embodiment, before determining the target RO, the target preamble sequence and the target PO, the following steps may be further included:

receiving resource configuration information; the resource configuration information comprises RO, a leader sequence, PO and a preset mapping rule, wherein the mapping rule comprises indication information used for indicating the number of resource blocks included in a PO group; and generating the mapping relation according to the resource configuration information.

Specifically, in one possible embodiment, the network device may configure Uplink transmission resources, where the Uplink transmission resources include Physical Random Access Channel (PRACH) resources and Physical Uplink Shared Channel (PUSCH) resources. The resource configuration information may include channel time frequency resources (RACH occupancy, RO) of a random access channel, preamble sequences, and time frequency resources (PUSCH occupancy, PO) of a physical uplink shared channel, and preset mapping rules among the RO, the preamble sequences, and the PO groups.

And the network equipment sends the resource configuration information, and the terminal equipment receives the resource configuration information. And the terminal equipment generates the mapping relation according to a preset mapping rule. It is to be understood that, in a possible implementation manner, according to the same preset mapping rule, the network device may also generate the same mapping relationship based on the resource configuration information.

In one possible embodiment, the network device may configure uplink transmission resources, where the uplink transmission resources include PRACH resources and PUSCH resources. In a possible embodiment, the network device may configure a plurality of resource blocks of the PUSCH physical layer, such as may be configured through RRC signaling. In the embodiment of the present invention, the size of one resource block (the resource block may refer to a resource block of a PUSCH physical layer) may be defined, for example, one resource block may be defined to include a plurality of unit resource blocks, where one unit resource block refers to that the unit resource block occupies 1 subcarrier in a frequency domain and occupies 1 time domain symbol in a time domain.

In a possible implementation manner, the number of unit resource blocks included in one resource block defined in the embodiment of the present invention may be related to a Modulation and Coding Scheme (MCS). For example, under a Quadrature Phase Shift Keying (QPSK) modulation and coding strategy, a resource block may be defined to include k0 unit resource blocks, where k0 is a positive integer.

In one possible embodiment, it may be required that an absolute value of a difference between the numbers of unit resource blocks included in any two resource blocks is not greater than a difference threshold. That is, the number of unit resource blocks included in each two resource blocks may not be equal, but the deviation cannot be greater than the difference threshold. In another possible embodiment, the difference between the numbers of unit resource blocks included in any two resource blocks may be required to be zero. That is, the number of unit resource blocks included in each two resource blocks is equal. It can be seen that, in the embodiment of the present invention, the number of unit resource blocks included in any two resource blocks may be limited, but specific location information of the unit resource blocks may not be limited, for example, time domains occupied by one resource block are 2 in total, occupied subcarriers are 12 in total, time domain symbols occupied by another resource block are 4 in total, and occupied subcarriers are 6 in total.

Based on the foregoing possible implementation manners, in an embodiment of the present invention, in one possible implementation manner, one PO group includes one or more POs, and one PO corresponds to one resource block; the number of resource blocks included in the first PO group is different from the number of resource blocks included in the second PO group; the set of target POs includes one or more target POs.

Correspondingly, the terminal device transmits the target preamble sequence on the target RO, and transmits the data to be transmitted on the resource block in the target PO group, including:

selecting a target DMRS sequence from one or more preset demodulation reference signal DMRS sequences; and transmitting the target preamble sequence on the target RO, and transmitting the data to be transmitted on the resource blocks corresponding to the target PO and the target DMRS sequence in the target PO group.

Based on the foregoing possible implementation manner, in this embodiment of the present invention, another possible implementation manner is that the mapping relationship includes: mapping relation of RO, a preamble sequence, PO and DMRS sequence, wherein one PO group comprises one or more POs, and one PO corresponds to one or more DMRS sequences; one PO and one DMRS sequence in the mapping relation correspond to one resource block; the number of resource blocks included in the first PO group is different from the number of resource blocks included in the second PO group; the set of target POs includes one or more target POs.

Accordingly, after the terminal device determines the target RO, the target preamble sequence and the target PO group, the method further includes:

Therefore, the terminal equipment can select a proper target PO group to transmit the data to be transmitted according to the data volume of the data to be transmitted, and compared with the scheme that the number of the resource blocks included in any two PO groups corresponding to two ROs is the same, in the embodiment of the invention, when smaller data needs to be transmitted, a PO group with a smaller number of the included resource blocks can be adopted, so that the problem of resource waste can be relieved, when larger data needs to be transmitted, a PO group with a larger number of the included resource blocks can be adopted, and therefore, when the data volume of the data to be transmitted is larger, the data can be transmitted in an inactive state.

Based on the above possible implementation manners, in the embodiment of the present invention, the mapping relationship satisfies one of the following:

Based on the above possible implementation manners, in an embodiment of the present invention, after the terminal device transmits the target preamble sequence on the target RO and transmits the data to be transmitted on the target PO group, the method further includes: and monitoring the random access response message MsgB in the random access response window.

In a possible implementation manner, the terminal device may be provided with multiple MCSs in the embodiment of the present invention. The terminal device may select a target MCS from a plurality of preset MCS levels according to the data amount of the data to be transmitted and the number of bits used for carrying data in the target PO group. Wherein the number of bits used for carrying data in the target PO group satisfies: and carrying out coding modulation on the data to be transmitted through the target MCS to obtain the data volume of the data. Transmitting the target preamble sequence on the target RO, transmitting on resource blocks in the target PO group: and obtaining data after the data to be transmitted is coded and modulated through the target MCS. Therefore, the terminal equipment can select a more suitable MCS for coding and modulating the data to be transmitted according to the data size of the data which needs to be transmitted actually, the channel condition and the like, and thus, the flexibility of the scheme can be increased.

step 300, determining resource configuration information; the resource configuration information comprises time-frequency resources RO of a physical random access channel PRACH, a leader sequence, time-frequency resources PO of a physical uplink shared channel PUSCH and preset mapping rules among the RO, the leader sequence and the PO groups; the mapping rule includes indication information for indicating the number of resource blocks included in one PO group;

in one possible embodiment, the network device may configure the uplink transmission resource, the uplink PRACH resource, and the PUSCH resource. The resource configuration information may include RO, preamble sequence, and PO, and preset mapping rules between the RO, preamble sequence, and PO groups.

Step 301, sending the resource configuration information;

In a possible embodiment, according to the same preset mapping rule, the network device and the terminal device may generate the same mapping relationship based on the resource configuration information.

Based on the above possible implementation manners, in this embodiment of the present invention, after the network device sends the resource configuration information, the method further includes:

the method comprises the steps that network equipment receives a random access request MsgA, wherein the random access request MsgA is used for requesting random access and comprises a target leader sequence and data to be transmitted; the target preamble sequence is transmitted through a target RO, and the data to be transmitted is transmitted through a resource block in a target PO group; the target RO, the target leader sequence, and the target PO group have a mapping relationship therebetween.

The random access request MsgA is used to request random access. The random access request MsgA comprises a target leader sequence and data to be transmitted. The target preamble sequence is transmitted through a target RO, and the data to be transmitted is transmitted through a resource block in a target PO group; the target RO, the target leader sequence, and the target PO group have a mapping relationship therebetween. The network device may perform a PUSCH decoding operation according to the position of the resource block in the target PO group associated with the target RO and the target preamble sequence, and further obtain data to be transmitted by the terminal device.

In one possible embodiment, after receiving the MsgA signal from the terminal device, the network device may blindly decode the signal of the resource block in the PO group by combining the MCS that code-modulates the signal, so as to obtain the information bits carried on the resource block of the specific PUSCH.

Based on the above possible implementation manners, in this embodiment of the present invention, after the network device receives the random access request MsgA, the method further includes: and sending a random access response message MsgB. And the terminal equipment monitors the random access response message MsgB in the random access response window. Subsequently, if the random access response message is a random access successful response, the terminal device may still maintain the inactive state after receiving the random access response MsgB because the terminal device has transmitted the data to be transmitted. In another possible embodiment, if the terminal device has other requirements, such as transmitting hundreds of megabytes or gigabytes of basic data, the terminal device may also enter active state after receiving the random access response MsgB.

In a possible implementation, one PO group of the mapping relationship includes one or more POs, and one PO corresponds to one resource block; the number of resource blocks included in the first PO group is different from the number of resource blocks included in the second PO group; the set of target POs includes one or more target POs.

In another possible implementation, the mapping relationship includes: mapping relation of RO, a preamble sequence, PO and DMRS sequence, wherein one PO group comprises one or more POs, and one PO corresponds to one or more DMRS sequences;

Further, the mapping relation satisfies one of the following:

In a possible embodiment, the mapping rule includes a rule of the number of resource blocks included in each PO group, or may be said to determine, according to the mapping rule, a PO group corresponding to each RO and the preamble sequence, and the number of resource blocks included in the PO group. This is described below by way of several examples.

In the embodiment of the present invention, for convenience of subsequent content introduction, a definition "aggregation factor" is introduced, where a value of the aggregation factor is a numerical value, and a value of an aggregation factor corresponding to a PO group is used to indicate a number of resource blocks included in the PO group. For example, if the value of the aggregation factor corresponding to a PO group is 1, it indicates that the PO group includes only one resource block. For another example, if the value of the aggregation factor corresponding to a PO group is 2, it indicates that the PO group includes only 2 resource blocks. For example, if the aggregation factor corresponding to a PO group has a value of 4, it indicates that the PO group includes only 4 resource blocks. For example, if the value of the aggregation factor corresponding to a PO group is 8, it indicates that the PO group includes only 8 resource blocks.

In order to more clearly describe the embodiment of the present invention, the following configuration information is described as an example in the following examples: the total number of Preamble sequences (which may also be written as Preamble index) configured by the network device is 2, which are Preamble index0 and Preamble index1, respectively. The number of Demodulation Reference Signal (DMRS) indications (also written as DMRS index) configured by the network device is 1, and the DMRS index is 0. Those skilled in the art will recognize that the configuration information is only an example, and in practical applications, more Preamble indexes and more DMRS indexes may also be configured, which is not limited in the embodiment of the present invention.

Example one, one aggregation factor per PUSCH slot. In this example, each of all PO groups in each PUSCH slot corresponds to the aggregation factor corresponding to the PUSCH slot.

In example one, the preset mapping rule satisfies the following condition: the T0 values are sequentially and circularly corresponding to the T1 PUSCH time slots according to a preset sequence; for one of the T1 PUSCH slots, the number of resource blocks included in each PO group in the PUSCH slot is the same as the value corresponding to the PUSCH slot. The T1 is a positive integer greater than 1, and the T0 is a positive integer greater than 1.

To introduce the first example more clearly, fig. 4 illustrates a schematic diagram of a possible correspondence relationship between aggregation factors and PUSCH slots, and as shown in fig. 4, one PRACH slot may correspond to one PUSCH slot. An aggregation factor cycle period may be set, which includes 4 aggregation factors, which are 1, 2, 4, and 8 in order. The 4 aggregation factors included in the one aggregation factor cycle period are the T0 values. In one possible mapping rule, it is specified that each PUSCH slot corresponds to one aggregation factor, and each aggregation factor in the aggregation factor cycle period may be sequentially and cyclically corresponding to a PUSCH slot according to the ordering of the PUSCH slots. As shown in fig. 4, if the aggregation factor corresponding to the PUSCH slot m is 1, each PO group in the PUSCH slot m includes 1 resource block. If the aggregation factor corresponding to the PUSCH slot m +1 is 2, each PO group in the PUSCH slot m +1 includes 2 resource blocks. If the aggregation factor corresponding to the PUSCH slot m +2 is 4, each PO group in the PUSCH slot m +2 includes 4 resource blocks. If the aggregation factor corresponding to the PUSCH slot m +3 is 8, each PO group in the PUSCH slot m +3 includes 8 resource blocks.

In example one, in one possible implementation, the resources in the PO group associated with one RO and the preamble sequence may be from the same PUSCH slot. It can also be said that all resource blocks included in the first RO belong to resource blocks in the same PUSCH slot; and all resource blocks included in the first PO group belong to the resource blocks in the same PUSCH time slot.

Fig. 5 exemplarily shows a corresponding relationship diagram of RO and PO, and as shown in fig. 5, the PRACH slot n +1 and the PUSCH slot m +1 in fig. 5 are taken as examples for explanation. As shown in fig. 5, PRACH slot n +1 includes three resource blocks, which are SSB 0RO #0, SSB1 RO #1, and SSB2 RO # 2. If the aggregation factor of the PUSCH slot m +1 is 2, it indicates that each PO group in the PUSCH slot m +1 includes 2 resource blocks.

In one possible embodiment, the total number of PO groups included in a PUSCH slot may be calculated by the following equation (1):

T_PUSCH＝floor(N_PO*N_DMRStotal/N_Aggregation) … … formula (1)

In the formula (1), T_PUSCHRepresenting a total number of PO groups included in the PUSCH slot; n is a radical of_POIndicates the total number of POs, N, included in one PUSCH slot_DMRStotalRepresenting the total number of DMRS indexes configured by the network equipment; n is a radical of_AggregationRepresents the value of the aggregation factor.

The total number of resource blocks included in a PRACH slot may be calculated by the following equation (2):

T_PRACH＝N_RO*N_preamble… … formula (2)

In the formula (2), T_PRACHIndicating the total of resource blocks included in a PRACH slotThe number of the particles; n is a radical of_ROIndicates the total number of ROs included in one PRACH slot, N_preambleThe total number of Preamble indexes representing the configuration of the network device.

The correspondence between the resource blocks included in the PRACH slot and the PO groups included in the PUSCH slot may be calculated by equation (3):

N_ratio＝ceil(T_PRACH/T_PUSCH) … … formula (3)

In the formula (3), T_PUSCHRepresenting a total number of PO groups included in the PUSCH slot; t is_PRACHRepresenting a total number of resource blocks included in a PRACH slot; n is a radical of_ratioAnd the corresponding relation between the resource blocks included in the PRACH time slot and the PO groups included in the PUSCH time slot is shown.

If in the example of fig. 5, the total number of Preamble indexes configured by the network device is 2. The number of configured DMRS indexes is 1. And as can be seen from fig. 5, the total number of POs included in the PUSCH slot m +1 is 6, and the value of the aggregation factor is 2, then T can be obtained according to the above formula (1)_PUSCH6 × 1/2 ═ 3. T can be obtained from the above formula (2)_PRACH3 x 2x 6. Based on these two values and in combination with equation (3) above, N can be calculated_ratio2. That is, two resource blocks in a PRACH slot (one resource block in the PRACH slot is determined by both the RO and the preamble sequence) correspond to one PO group in the PUSCH or to the DMRS Index in one PO group + PO group. The correspondence in this example can be shown by table 1 below. Table 1 below illustrates a schematic table of a possible correspondence relationship between RO, preamble sequence and PO, and as shown in table 1, each resource block in a PRACH slot may be ordered, and a resource block in one PRACH slot may be defined by two parameters, that is, RO and preamble sequence. The resource blocks in the PRACH slot may be ordered according to a preset order of ROs, and for a plurality of resource blocks corresponding to each RO, the resource blocks may be ordered according to a preset order of a plurality of preamble sequences configured by the network device.

As shown in table 1, each resource block in a PUSCH slot may be ordered, and a resource block in one PUSCH slot may be defined by two parameters, namely PO and DMRS index. The resource blocks in the PUSCH slot may be sorted according to a preset order of POs, and for a plurality of resource blocks corresponding to each PO, the resource blocks may be sorted according to a preset order of DMRS index configured by the network device. And then, according to a preset PO group division rule, dividing the resource blocks in the PUSCH time slot into different PO groups. And then, according to the value 2 determined by the formula (3), two resource blocks in the PRACH slot are corresponding to one PO group, that is, according to the sequence of the resource blocks in the PRACH slot and the sequence of the PO groups in the PUSCH slot, the corresponding relationship between the resource blocks in each two PRACH slots and one PO group in the PUSCH slot is sequentially established.

In table 1, a second behavior example in table 1 is introduced, and as shown in table 1, a resource block SSB 0RO #0 and a Preamble sequence Preamble index0 of a PRACH are associated with a PO group #1 in a PUSCH slot, and the resource blocks included in the PO group #1 are: PO #0, DMRS index 0; and resource blocks corresponding to PO #1 and DMRS index 0. The rest of Table 1 is similar and will not be described.

TABLE 1

Fig. 6 exemplarily shows another corresponding relationship diagram of ROs and POs, and in the example of fig. 6, the total number of Preamble indexes configured by the network device is 2. The number of configured DMRS indexes is 3. And as can be seen from fig. 6, if the total number of POs included in the PUSCH slot m +1 is 6 and the value of the aggregation factor is 2, T can be obtained according to the above formula (1)_PUSCH6 × 3/2 ═ 9. T can be obtained from the above formula (2)_PRACH3 x 2x 6. Based on these two values and in combination with equation (3) above, N can be calculated_ratio1. That is, 1 resource block in the PRACH slot (one resource block in the PRACH slot is determined by both the RO and the preamble sequence) corresponds to one PO group in the PUSCH + DMRS Index in the PO group. The correspondence in this example can be demonstrated by table 2 below.

TABLE 2

As shown in table 2, each resource block in a PUSCH slot may be ordered, and the resource block in one PUSCH slot may be defined by two parameters, namely PO and DMRS index. The resource blocks in the PUSCH slot may be sorted according to a preset order of POs, and for a plurality of resource blocks corresponding to each PO, the resource blocks may be sorted according to a preset order of DMRS index configured by the network device. And then, according to a preset PO group division rule, dividing the resource blocks in the PUSCH time slot into different PO groups.

Since the resource block of PUSCH (one resource block in a PUSCH slot is jointly determined by PO and DMRS). According to FIG. 6, although N_ratioHowever, since the number of PUSCH resource blocks is greater than the number of PRACH resource blocks, there is a remainder of PUSCH resources. A schematic table 2 of a specific possible correspondence relationship between RO, preamble sequence, and PO and DMRS is shown. As shown in table 2, since DMRS resources in each PO group are 3, the mapping result shows that only two PO groups (PO group #1 and PO group #2) are used in the mapping. Fig. 7 exemplarily shows a corresponding relationship diagram of still another RO and PO, and in the example of fig. 7, the total number of Preamble indexes configured by the network device is 2. The number of the configured DMRS index resource combinations is 9 (because each PO group includes 2 PO resource blocks, each resource block is configured with 3 DMRS indexes, and two resource blocks are configured with one DMRS index respectively to form a new DMRS index combination resource, which is specifically shown in table 3). And as can be seen from fig. 7, if the total number of POs included in the PUSCH slot m +1 is 6 and the value of the aggregation factor is 2, T can be obtained according to the above formula (1)_PUSCH6 × 9/2 ═ 27. T can be obtained from the above formula (2)_PRACH3 x 2x 6. Based on these two values and in combination with equation (3) above, N can be calculated_ratio1. That is, 1 resource block in the PRACH slot (one resource block in the PRACH slot is determined by both the RO and the preamble sequence) corresponds to one PO group in the PUSCH + DMRS Index in the PO group. Correspondence in this exampleCan be demonstrated by the following table 4. According to table 4, all PRACH resources correspond to resources within PO group # 1.

TABLE 3

TABLE 4

Example two, each PUSCH slot corresponds to all aggregation factors within one aggregation factor cycle period. For example, if all the aggregation factors included in one cycle of aggregation factors include 1 and 2. Then, in this example, there is one PO group including 1 resource block and there is also one PO group including 2 resource blocks in all PO groups in each PUSCH slot.

In this example, in one possible implementation manner, the total number of physical layer resource blocks in one PUSCH slot (which may also be referred to as the total number of POs in one PUSCH slot) is not less than the maximum value of all aggregation factors corresponding to the slot, for example, if the aggregation factor corresponding to one PUSCH slot includes 1 and 2, and the maximum value of the aggregation factor corresponding to the PUSCH slot is 2, the total number of physical layer resource blocks of the PUSCH slot may be required to be not less than 2. As such, it can be achieved that all aggregation factors corresponding to all PO groups in the PUSCH slot include 1 and 2. In a possible embodiment, the physical layer resource blocks in the PUSCH slot may be divided according to all aggregation factors corresponding to the PUSCH slot, so as to obtain multiple PO groups, and one RO may correspond to one or multiple PO groups.

In this embodiment of the present invention, the multiple groups of POs corresponding to one RO may be from different PUSCH slots or from the same PUSCH slot, which is not limited in the embodiment of the present invention.

In example two, the preset mapping rule satisfies the following condition: the preset mapping rule meets the following conditions: for T2 PO groups in one of T1 PUSCH slots, the T0 values sequentially cycle to correspond to the T2 PO groups according to a preset ordering; for one PO group in the T2 PO groups, the PO group comprises the same number of resource blocks as the corresponding numerical value of the PO group. Wherein, the T1 is a positive integer, the T2 is a positive integer greater than 1, and the T0 is a positive integer greater than 1.

If all the polymerization factors included in one cycle of polymerization factors include 1 and 2. Table 5 illustrates a schematic table of correspondence of possible RO, leader sequence and PO groups. As shown in table 5, the preset rule specifies a division method of the PO group, and as shown in table 5, the PO group #0 includes the PO #0 and the resource blocks corresponding to the DMRS index0, and the PO group #1 includes the PO #0 and the DMRS index0, and the PO #1 and the resource blocks corresponding to the DMRS index 0. As can be seen, PO group #0 includes 1 resource block and PO group #1 includes 2 resource blocks.

In one possible embodiment, the total number of PO groups included in the PUSCH slot may be calculated by the following equation (4):

T_PUSCH＝floor(N_PO*N_DMRStotal/N_{Aggregation max}) … … formula (4)

In the formula (4), T_PUSCHRepresenting a total number of PO groups included in the PUSCH slot; n is a radical of_POIndicates the total number of POs, N, included in one PUSCH slot_DMRStotalRepresenting the total number of DMRS indexes configured by the network equipment; n is a radical of_{Aggregation max}Represents the maximum value of all aggregation factors included in the PUSCH slot.

The correspondence between the resource blocks included in the PRACH slot and the PO groups included in the PUSCH slot may be calculated by equation (5):

N_ratio＝ceil(N_RO/T_PUSCH) … … formula (5)

In the formula (5), N_RORepresenting a total number of ROs included in a PRACH slot; t is_PUSCHRepresenting a total number of PO groups included in the PUSCH slot; n is a radical of_ratioAnd the corresponding relation between the resource blocks included in the PRACH time slot and the PO groups included in the PUSCH time slot is shown.

T can be obtained from the above formula (4)_PUSCHN can be calculated from the above equation (5) by 6 × 1/2 ═ 3_ratio＝ceil(N_RO/T_PUSCH) Ceil (3/3) is 1. That is, one resource block in the PRACH slot (one resource block in the PRACH slot is determined by both the RO and the preamble sequence) corresponds to one PO group in the PUSCH. The correspondence in this example can be shown by table 5 below. How resource blocks in one PUSCH in table 5 divide a PO group may be a pre-configured division rule. Fig. 8 exemplarily shows a correspondence diagram of RO and PO groups shown in table 5.

TABLE 5

Example three, each PUSCH slot corresponds to all aggregation factors within one aggregation factor cycle period. For example, if all the aggregation factors included in one cycle of aggregation factors include 1 and 2. Then, in this example, there is at least one PO group among all PO groups in each PUSCH slot that includes 1 resource block, and there is also at least one PO group that includes 2 resource blocks.

As can be seen from table 5, there is one overlapping resource block between PO group #0 and PO group #1, that is, a resource block corresponding to PO #0 and DMRS index 0. The difference between example two is: in example three, in one possible embodiment, for two PO groups in one PUSCH slot, optionally, the two PO groups include resource blocks without overlapping resource blocks, so that the interference problem between the PO groups can be reduced.

In example three, if all the aggregation factors included in one aggregation factor cycle period include 1 and 2. Table 6 illustrates a schematic table of correspondence of possible RO, preamble sequence and PO groups. As shown in table 6, the preset rule specifies a division method of the PO group, and as shown in table 6, the PO group #0 includes the PO #0 and the resource blocks corresponding to the DMRS index0, and the PO group #1 includes the PO #1 and the DMRS index0, and the PO #2 and the DMRS index 0. As can be seen, PO group #0 includes 1 resource block and PO group #1 includes 2 resource blocks. And there is no overlap of resource blocks between PO group #0 and PO group # 1.

In one possible embodiment, the total number of PO groups included in the PUSCH slot may be calculated by the following equation (6):

T_PUSCH＝floor(N_PO*N_DMRStotal*T_{Aggregation Total}/∑j_{aggregation value}) … … formula (6)

In the formula (6), T_PUSCHRepresenting a total number of PO groups included in the PUSCH slot; n is a radical of_POIndicates the total number of POs, N, included in one PUSCH slot_DMRStotalRepresenting the total number of DMRS indexes configured by the network equipment; t is_{Aggregation Total}Represents the total number of all aggregation factors, Σ j, included in a PUSCH slot_{aggregation value}Represents the sum of the values of all aggregation factors included in the PUSCH slot.

T can be obtained from the above equation (6) and the parameters in Table 6_PUSCHN can be calculated from the above formula (3) by 9 × 1 × 2/3 × 6_ratio＝ceil(N_RO/T_PUSCH) Ceil (6/6) is 1. That is, one resource block in the PRACH slot (one resource block in the PRACH slot is determined by both the RO and the preamble sequence) corresponds to one PO group in the PUSCH. The correspondence in this example can be shown by table 6 below. How resource blocks in one PUSCH in table 6 divide a PO group may be a pre-configured division rule. Fig. 9 exemplarily shows a correspondence relationship diagram of the RO and PO groups shown in table 6.

TABLE 6

Example four, each PUSCH slot corresponds to all aggregation factors within one aggregation factor cycle period. For example, if all the aggregation factors included in one cycle of aggregation factors include 1 and 2. Then, in this example, there is at least one PO group among all PO groups in each PUSCH slot that includes 1 resource block, and there is also at least one PO group that includes 2 resource blocks.

The examples in the first example, the second example, and the third example are all described by taking one PRACH slot corresponding to one PUSCH slot as an example. One PRACH slot may also correspond to multiple PUSCH slots. In one possible embodiment, the resource blocks in the first RO and the second RO belong to the same PUSCH slot. And the PUSCH time slot corresponding to the resource block in the first PO group is different from the PUSCH time slot corresponding to the resource block in the second PO group. Specifically, this example four can be used to explain the present invention.

In example four, if all the aggregation factors included in one aggregation factor cycle period include 1 and 2. Table 7 exemplarily shows a correspondence relationship schematic table of possible RO, preamble sequence and PO group. As shown in table 7, the preset rule specifies the division method of the PO group, and as shown in table 7, the PO group #0 includes resource blocks in the PUSCH slot j, specifically, the PO group #0 includes resource blocks corresponding to the PO group #0 in the PUSCH slot j and the DMRS index0, and the PO group #1 includes resource blocks corresponding to the PO #1 and the DMRS index0 in the PUSCH slot j, and the PO #2 and the DMRS index0 in the PUSCH slot j. The PO group #2 includes resource blocks corresponding to the PUSCH slot j +1, specifically, the PO group #2 includes resource blocks corresponding to the PO #3 and the DMRS index0 in the PUSCH slot j +1, and the PO group #3 includes resource blocks corresponding to the PO #4 and the DMRS index0 in the PUSCH slot j +1, and the PO #5 and the DMRS index0 in the PUSCH slot j + 1. As can be seen, PO group #0 includes 1 resource block and PO group #1 includes 2 resource blocks. And PO group #0 and PO group #1 belong to the PUSCH slot j. PO group #2 includes 1 resource block, and PO group #3 includes 2 resource blocks. And PO group #2 and PO group #3 belong to the same PUSCH slot j + 1. And SSB 0RO #0 and SSB1 RO #1 both belong to PRACH slot i, and SSB 0RO #0 is associated with Preamble index0 to PO group #0, SSB 0RO #0 is associated with Preamble index1 to PO group #1, SSB1 RO #1 is associated with Preamble index0 to PO group #2, and SSB1 RO #1 is associated with Preamble index1 to PO group # 3.

Example four differs from example three in that PO group #0 and PO group #1 are located in PUSCH slot j, PO group #2 and PO group #3 are located in PUSCH slot j +1, and PO group #4 and PO group #5 are located in PUSCH slot j + 2. The rest can be seen in the discussion in example three. And the correspondence in this example four can be shown by the following table 7. How resource blocks in one PUSCH in table 7 divide a PO group may be a pre-configured division rule. Fig. 10 exemplarily shows a correspondence diagram of RO and PO groups shown in table 7.

TABLE 7

Example five, in a possible application scenario, if the number of POs included in the PUSCH slot is small, in this case, when dividing PO groups, resource blocks in two adjacent PO groups may overlap, and the same PO may also be correspondingly divided into multiple PO groups. This is illustrated by example five.

In this example, in one possible implementation manner, the total number of physical layer resource blocks in one PUSCH slot (which may also be referred to as the total number of POs in one PUSCH slot) is not less than the maximum value of all aggregation factors corresponding to the slot, for example, if the aggregation factor corresponding to one PUSCH slot includes 1 and 2, and the maximum value of the aggregation factor corresponding to the PUSCH slot is 2, the total number of physical layer resource blocks of the PUSCH slot may be required to be not less than 2. As such, it can be achieved that all aggregation factors corresponding to all PO groups in the PUSCH slot include 1 and 2.

If all the polymerization factors included in one cycle of polymerization factors include 1 and 2. Table 8 exemplarily shows a correspondence relationship schematic table of possible RO, preamble sequence and PO group. As shown in table 8, the preset rule specifies a division method of the PO group, and as shown in table 8, the PO group #0 includes the PO #0 and the resource blocks corresponding to the DMRS index0, and the PO group #1 includes the PO #0 and the DMRS index0, and the PO #1 and the resource blocks corresponding to the DMRS index 0. As can be seen, PO group #0 includes 1 resource block and PO group #1 includes 2 resource blocks.

In one possible embodiment, the total number of PO groups included in the PUSCH slot may be calculated by the following equation (7):

T_PUSCH＝floor(N_PO*N_DMRStotal*N_{Aggregation max}) … … formula (7)

In the formula (7), T_PUSCHRepresenting a total number of PO groups included in the PUSCH slot; n is a radical of_POIndicates the total number of POs, N, included in one PUSCH slot_DMRStotalRepresenting the total number of DMRS indexes configured by the network equipment; n is a radical of_{Aggregation max}Represents the maximum value of all aggregation factors included in the PUSCH slot.

T can be obtained from the above equation (7)_PUSCH3 x1 x 2x 6. N can be calculated according to the formula (3)_ratio＝ceil(T_PRACH/T_PUSCH) Ceil (6/6) is 1. That is, one resource block in the PRACH slot (one resource block in the PRACH slot is determined by both the RO and the preamble sequence) corresponds to one PO group in the PUSCH. The correspondence in this example can be shown by table 8 below. How the resource block in one PUSCH in table 8 divides the PO groups may be a pre-configured division rule, for example, the PO groups may be sequentially and circularly divided based on the ordering of PO #0, PO #1, and PO #2, which is specifically referred to in table 8. Fig. 11 exemplarily shows a correspondence relationship diagram of RO and PO groups shown in table 8.

TABLE 8

By way of example one to example five, it can be seen that a network device may configure multiple PO groups, and the number of physical layer resource blocks included in two PO groups may be different, so that a terminal device may select a suitable group according to the size of data to be transmitted: RO, preamble, and PO groups to send MsgA. On the other hand, if the data volume of the data to be transmitted is large, a possible implementation manner is that the terminal device does not find the PO group capable of bearing the data to be transmitted, so that the terminal device can enter an active state through a random access process, and further transmit the data to be transmitted in the active state.

In another possible embodiment, when the data volume of the data to be transmitted is large, the terminal device may divide the data to be transmitted, for example, the data to be transmitted may be divided into two parts, so that the data volume of the data to be transmitted at one time may be reduced, and thus, a part of the data may be transmitted in the inactive state, and the rest of the data may be transmitted in the active state or in the inactive state.

Fig. 12 is a schematic structural diagram of a data transmission apparatus according to an embodiment of the present invention, and as shown in fig. 12, the data transmission apparatus may be a terminal device, and includes a first determining module 1001 and a processing module 1002, where:

the first determining module 1001 is configured to determine a target RO, a target preamble sequence, and a target PO group according to a data amount of data to be transmitted and a mapping relationship between a time-frequency resource RO of a physical random access channel PRACH, the preamble sequence, and a time-frequency resource PO group of a physical uplink shared channel PUSCH; the processing module 1002 is configured to transmit the target preamble sequence on the target RO, and transmit the data to be transmitted on the resource block in the target PO group; the number of bits used for carrying data in the target PO group meets the data volume of the data to be transmitted;
