Background

In an industrial environment, most applications require that information be sent periodically, for example, to a particular device in order for it to perform a particular operation. Compared with a dynamic resource scheduling mode, a semi-persistent resource configuration mode can reduce the time delay of User Equipment (UE, also called a terminal) for sending a scheduling request and the signaling overhead generated by sending the scheduling request, and is suitable for sending periodic data.

Currently, a BWP of a UE can only configure a set of semi-persistent resources and only configure a very limited number of transmission resources (e.g., 1 time domain transmission resource) within a transmission period of the set of semi-persistent resources, so that when the configured semi-persistent transmission resources are not enough to transmit all data to be transmitted of the UE, the BWP can only wait for the next semi-persistent resource period, resulting in a delay in data transmission.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

In making the description of the embodiments of the present invention, some concepts used in the following description will first be explained.

One, semi-persistent resource allocation

In the current 5G system, a semi-persistent data transmission resource may be configured for a User Equipment (UE, also referred to as a terminal), and the method mainly includes:

downlink Semi-Persistent Scheduling (DL SPS, Downlink Semi-Persistent Scheduling)

Uplink configuration authorization Type 1(UL configured grant Type 1)

Uplink configuration authorization Type 2(UL configured grant Type 2)

Autonomous Uplink (AUL)

Several semi-persistent data transmission resources are described below.

The DL SPS is configured with periodic downlink resources by a network side, and each period has 1 downlink resource allocation. The network side activates or deactivates the use of the SPS resource through a Physical Downlink Control Channel (PDCCH) Control signaling, and the PDCCH command indicates an activated resource location (e.g., SFN)_{start time}(initial System frame number) and slot_{start time}(starting slot number)) is the starting position of the resource. The UE calculates the nth resource location by formula one:

formula one, (numberOfSlotsPerFrame x SFN + slot number in the frame) ═

[(numberOfSlotsPerFrame×SFN_{start time}+slot_{start time})+N×periodicity×numberOfSlotsPerFrame/10]modulo(1024×numberOfSlotsPerFrame)

The number of Hybrid Automatic repeat request (HARQ) processes of the DL SPS for a specific slot is calculated by formula two:

formula two, HARQ Process ID ═ floor (CURRENT _ slot × 10/(number of slot frame × periodic)) ] modulo nrofHARQ-Processes

Wherein, CURRENT _ slot is the slot number of the CURRENT resource, and CURRENT _ slot ═ SFN × number of slot frame) + slot number in the frame (the slot number of the CURRENT system frame) ]; sfn (system Fram number) is the current system frame number; the number of the time slots contained in each system frame is the number of the time slots contained in each system frame; the periodicity is an SPS Resource period configured by a Radio Resource Control (RRC) message; the nrofHARQ-Processes is the number of HARQ Processes of the SPS resource configured by the RRC message.

The network side configures periodic uplink resources for UL configured grant Type 1, and each period has 1 uplink resource allocation. RRC configured may be used without PDCCH order activation. The UE calculates the Nth resource position by the formula three:

equation three, [ (SFN × number of SlotsPolframe × number of SymbolsPol Slot) + (slot in the frame × number of SymbolsPol Slot) + symbol number in the slot ] }

(timeDomainOffset×numberOfSymbolsPerSlot+S+N×periodicity)modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)

Wherein, the number of symbol (i.e. Orthogonal Frequency Division Multiplex (OFDM) symbol) of each slot is numberofsymbolserslot; timeDomainOffset is the resource offset (e.g., slot 1) relative to the time domain with SFN ═ 0; n is the serial number of the resource; s is the number of the starting symbol (e.g., for slot 1 position, the starting symbol is OFDM symbol 1).

The HARQ process number of the UL configured grant Type 1 for a specific slot (slot) is calculated by formula four:

formula four, HARQ Process ID [ floor (CURRENT _ symbol/priority) ] modulonof HARQ-Processes

Wherein, CURRENT _ symbol is a symbol number corresponding to the CURRENT resource, and CURRENT _ symbol ═ SFN × number of slot frame × number of symbol spot slot + slot number in the slot (symbol number of the CURRENT slot)); the number of symbols per slot is the number of symbols per symbol.

And configuring the periodic uplink resource by the network side in the UL configured grantType 2, wherein each period has 1 uplink resource allocation. The network side activates or deactivates the use of the SPS resources through PDCCH control signaling, and the PDCCH order indicates the activated resource location (e.g., SFN)_{start time}(initial System frame number) and slot_{start time}(initial slot number) and symbol_start _time(starting symbol number)) is the starting location of the resource. The UE calculates the nth resource location by formula five:

[(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number inthe frame×numberOfSymbolsPerSlot)+symbol number in the slot]＝

[(SFN_start _time×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot_start _time×numberOfSymbolsPerSlot+symbol_start _time)+N×periodicity]modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)

the HARQ process number of the UL configured grant Type 2 for a specific slot is calculated by the same calculation formula as the UL configured grant Type 1.

The AUL configures resource allocation of a bitmap (e.g., if 1 bit value is set to 1 in 40 bits, the resource is allocated to the UE) from the network side. The network side activates or deactivates the AUL resource usage through PDCCH control signaling, and the PDCCH order indicates the activated resource location (such as SFN)_start _time(initial System frame number) and slot_{start time}(initial slot number) and symbol_{start time}(starting symbol number)) is the starting location of the resource. When the UE has uplink data transmission, one HARQ process is autonomously selected from a HARQ process pool configured by a network side for transmission.

Second, Bandwidth Part (BWP) introduction

In a 5G system, the UE may only support a relatively small operating bandwidth (e.g. 5MHz), while a cell on the network side may support a relatively large bandwidth (e.g. 100MHz), in which the small bandwidth part of the UE operating is considered as BWP. From the UE configuration perspective, the BWP may be a BWP under 1 cell for different UE functions. Multiple different BWPs employ the same HARQ entity.

The network side may configure the UE with 1 or more BWPs, and may change the currently activated BWP of the UE through a BWP switching command (e.g., PDCCH indication information), i.e., activate a new BWP and deactivate the currently activated BWP. Currently the UE can only activate 1 BWP for 1 cell.

Additionally, the network side may configure a BWP inactivity timer (BWP-inactivity timer) for one active BWP, and the UE starts after 1 BWP is activated and then changes the active BWP to the default BWP (default BWP) after the timer expires.

Third, industry internet of things (IIOT) project background

RAN #80 conference agreed to IIOT standing. In an industrial environment, many applications (e.g., manufacturing, machine control, etc.) have high performance requirements, such as low latency, high reliability, and directional information transfer. The IIOT project is intended to provide a LAN type communication service for such vertical industries through a 5G communication network, meeting the communication demands of the vertical industries.

In an industrial environment, most applications require that information be sent periodically, for example, to a particular device in order for it to perform a particular operation. Compared with a dynamic resource scheduling mode, the semi-persistent resource configuration mode can reduce the time delay of the UE for sending the scheduling request. Currently, only a very limited number of transmission resources (e.g., transmission resources of 1 time domain) can be configured in one semi-persistent transmission period of the UE, so that when the transmission resources are not enough to transmit all the to-be-transmitted data of the UE, only the next semi-persistent resource period can be waited for, resulting in a delay in data transmission.

In the prior art, one BWP configures only one semi-persistent resource, and one serving cell can activate only one semi-persistent resource at any point in time. When a network side configures a plurality of different semi-persistent resources (e.g., SPS) on a certain BWP of a serving cell, how to allocate a plurality of active semi-persistent resources on the BWP becomes a problem to be solved.

As shown in fig. 1, an embodiment of the present invention provides a data transmission method, which is applied to a terminal, and includes:

step 101, acquiring resource configuration information in a first frequency domain range, wherein the resource configuration information comprises configuration information of at least two sets of semi-persistent resources;

it should be noted that the first frequency domain range refers to a BWP, that is, the BWP has at least two sets of configuration information of semi-persistent resources; the at least two sets of semi-persistent resources refer to at least two semi-persistent resource configurations, i.e., each set of semi-persistent resources actually refers to each semi-persistent resource configuration.

102, acquiring a target hybrid automatic repeat request (HARQ) process number of a target resource in each set of semi-persistent resources according to the resource configuration information;

the step is to obtain the number of the HARQ process corresponding to the data transmission of one or more resources in each semi-persistent resource configuration.

And 103, adopting the HARQ process corresponding to the target HARQ process number to carry out data transmission at the position of the target resource.

When the HARQ process number of a specific resource is obtained, when data transmission is performed by using the resource, the data transmission needs to be performed by using the HARQ process corresponding to the HARQ process number corresponding to the resource.

The semi-persistent resources include: downlink semi-persistent scheduling resources, an uplink configuration authorization type I, an uplink configuration authorization type II and autonomous uplink resources; the resource allocation information corresponding to each type of semi-persistent resource is also different, and the following description specifically describes the resource allocation information from different resource types.

A1, when the semi-persistent resource is: when the downlink semi-persistent scheduling resource, the uplink configuration authorization type two or the autonomous uplink resource, the resource configuration information includes at least one of the following information:

a11, the period of each set of semi-persistent resources is, for example, 20ms, that is, the terminal has available resources configured on the network side every 20 ms.

A12, resource allocation information of each set of semi-persistent resources in each period.

A2, when the semi-persistent resource is: when the uplink configuration authorization type is one, the resource configuration information includes at least one of the following information:

a21, the period of each set of semi-persistent resources;

a22, time domain offset of each set of semi-persistent resources;

a23, the time domain length occupied by each time domain resource of each set of semi-persistent resources;

Wherein the reference signal identification comprises at least one of the following information:

B3, at least one time domain resource allocation information;

the time domain resource allocation information includes: the resource allocation duration.

It should be further noted that, when the semi-persistent resources are: when the downlink semi-persistent scheduling resource, the uplink configuration authorization type one, the uplink configuration authorization type two or the autonomous uplink resource, the resource configuration information further includes: HARQ configuration information available to the terminal over a first frequency domain range.

Specifically, the HARQ configuration information available to the terminal in the first frequency domain range includes at least one of the following information:

c1, numbering the HARQ processes available for each set of semi-persistent resources in the first frequency domain range;

it should be noted that, each set of HARQ process numbers available for the semi-persistent resources may be a continuous natural number, for example, the set of HARQ process numbers available for the semi-persistent resources is: 1. 2,3 and 4, another set of HARQ processes available for semi-persistent resources is numbered as: 5. 6,7 and 8; each set of HARQ process numbers available for semi-persistent resources may be a discrete natural number, for example, the set of HARQ process numbers available for semi-persistent resources is: 1. 3,5 and 7, and the number of the other set of HARQ processes available for the semi-persistent resource is: 2. 4,6 and 8.

C2, the number of HARQ processes available in each period of each set of semi-persistent resources;

for example, the number of HARQ processes available in each period of one set of semi-persistent resources is 2, and the number of HARQ processes available in each period of the other set of semi-persistent resources is 4.

The implementation of step 102 is specifically described below in different cases.

If each set of semi-persistent resources has an available HARQ process in each period, and the number of the available HARQ processes of each set of semi-persistent resources is a discrete natural number; or

If each set of semi-persistent resources has at least two available HARQ processes in each period;

the specific implementation manner of step 102 is:

acquiring the HARQ process number of the initial resource in each set of semi-persistent resources;

and determining the target HARQ process number of the target resource in each period of each set of semi-persistent resources by taking the HARQ process number of the initial resource in each set of semi-persistent resources as a starting point and according to a preset rule.

Further, the semi-persistent resources include: under the condition of downlink semi-persistent scheduling resources, the obtaining of the HARQ process number of the initial resource in each set of semi-persistent resources includes:

according to the following preset formula:

HARQ Process ID_start＝[floor(CURRENT_slot_{start time}×10/(numberOfSlotsPerFrame×periodicity))]obtaining the HARQ process number of the initial resource in each set of semi-persistent resources by a modulo (nrofHARQ-Processes/nrofHARQ-processPasPeriod) + offset _ sps;

wherein, HARQ Process ID_startNumbering HARQ processes of initial resources in each set of semi-persistent resources; CURRENT slot_{start time}Numbering time slots of the initial resources; the number of the time slots contained in each system frame is the number of the time slots contained in each system frame; the period is the period of the semi-persistent resource to which the initial resource belongs; nrofHARQ-Processes is the number of HARQ Processes of the semi-persistent resource to which the initial resource belongs; nrofHARQ-ProcessSperPeriod is each of the semi-persistent resources to which the target resource belongsThe number of HARQ processes available for each period; the offset _ sps is an initial value of an available HARQ process number of a semi-persistent resource to which the initial resource belongs; floor (×) represents a down-rounding function; modulo is a modulo operation.

Note that CURRENT _ slot_{start time}The specific acquisition mode is as follows: numberOfSlotsPerFrame x SFN_{start time}+slot_{start time}And (6) obtaining.

It should be noted that, in this case, each set of semi-persistent resources may have one or more HARQ processes available in each period, and when each set of semi-persistent resources has one HARQ process available in each period, the value of nrofHARQ-processpersperiod is 1, that is, the above formula becomes:

HARQ Process ID_start＝[floor(CURRENT_slot_{start time}×10/(numberOfSlotsPerFrame×periodicity))]modulo nrofHARQ-Processes+offset_sps。

further, the semi-persistent resources include: under the condition of the uplink configuration authorization type one or the uplink configuration authorization type two, the obtaining of the HARQ process number of the initial resource in each set of semi-persistent resources includes:

HARQ Process ID_start＝[floor(CURRENT_symbol_{start time}/periodicity)]obtaining the HARQ process number of the initial resource in each set of semi-persistent resources by a modulo (nrofHARQ-Processes/nrofHARQ-processPasPeriod) + offset _ sps;

wherein, HARQ Process ID_startNumbering HARQ processes of initial resources in each set of semi-persistent resources; current _ symbol_{start time}Numbering the symbols of the starting resource; the period is the period of the semi-persistent resource to which the initial resource belongs; nrofHARQ-Processes is the number of HARQ Processes of the semi-persistent resource to which the initial resource belongs; the nrofHARQ-ProcessSperPeriod is the number of HARQ processes available in each period of the semi-persistent resource to which the target resource belongs; the offset _ sps is an initial value of an available HARQ process number of a semi-persistent resource to which the initial resource belongs; floor (×) represents a down-rounding function; modulo is a modulo operation.

Need to explainThat is, CURRENT _ symbol when the grant type one is configured for the uplink_{start time}The specific acquisition mode is as follows: (timeDomainOffset x numberOfSymbolsPerSlot + S).

When the authorization type two is configured for uplink, CURRENT _ symbol_{start time}The specific acquisition mode is as follows: (SFN_{start time}×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot_{start time}×numberOfSymbolsPerSlot+symbol_{start time}) And (6) obtaining.

It should be noted that, in this case, each set of semi-persistent resources may have one or more HARQ processes available in each period, and when each set of semi-persistent resources has one HARQ process available in each period, the value of nrofHARQ-processpersperiod is 1, that is, the formula is changed as follows:

HARQ Process ID_start＝[floor(CURRENT_symbol_{start time}/periodicity)]modulonrofHARQ-Processes+offset_sps。

specifically, in the above case, if each set of semi-persistent resources has one HARQ process available in each period, the preset rule includes: and circularly using according to the number of the available HARQ process of each set of semi-persistent resources. For example, the available HARQ processes for each set of semi-persistent resources are numbered 1,3, and 5, in this case, the first period is 1, the second period is 3, the third period is 5, and the subsequent periods are cycled through in the order of 1,3, and 5.

If each set of semi-persistent resources has at least two available HARQ processes in each period, the preset rule includes: and circularly using according to the number of the available HARQ process of each resource in each set of semi-persistent resources. For example, the available HARQ processes for each set of semi-persistent resources are numbered 2,4,6, and 8, then in this case, the first period is used for 2 and 4, the second period is used for 6 and 8, and the subsequent periods are recycled according to the grouping order of 2 and 4 and 6 and 8.

Secondly, the semi-persistent resources comprise: under the condition of downlink semi-persistent scheduling resources, if each set of semi-persistent resources has one available HARQ process in each period and the number of the available HARQ processes of each set of semi-persistent resources is a continuous natural number, the specific implementation manner of step 102 is as follows:

according to the following preset formula:

acquiring a target HARQ Process number of a target resource in each set of semi-persistent resources by using a HARQ Process ID ═ floor (CURRENT _ slot × 10/(number of Slot sPerFrame × periodic)) ] modulo nrofHARQ-Processes + offset _ sps;

wherein, the HARQ Process ID is the target HARQ Process number of the target resource in each set of semi-persistent resources; CURRENT _ slot is the time slot number of the target resource; the number of the time slots contained in each system frame is the number of the time slots contained in each system frame; the period is the period of the semi-persistent resource to which the target resource belongs; nrofHARQ-Processes is the number of HARQ Processes of the semi-persistent resource to which the target resource belongs; the offset _ sps is an initial value of an available HARQ process number configured for the semi-persistent resource to which the target resource belongs; floor (×) represents a down-rounding function; modulo is a modulo operation.

It should be noted that, the specific obtaining manner of CURRENT _ slot is according to the formula: CURRENT _ slot ═ (SFN × number of slot frame) + slot number in the frame.

It should be noted that, when each set of semi-persistent resources has one available HARQ process in each period, that is, each resource uses the same HARQ process in each period, the HARQ process number corresponding to each resource in each set of semi-persistent resources may be calculated according to the above formula.

Thirdly, the semi-persistent resources comprise: under the condition of the uplink configuration grant type one or the uplink configuration grant type two, if each set of semi-persistent resources has one available HARQ process in each period and the number of the HARQ processes available for each set of semi-persistent resources is a continuous natural number, the specific implementation manner of step 102 is as follows:

according to the following preset formula:

acquiring a target HARQ Process number of a target resource in each set of semi-persistent resources by using a HARQ Process ID (floor (Current _ symbol/periodicity)) module n-of HARQ-Processes + offset _ sps;

wherein, the HARQ Process ID is the target HARQ Process number of the target resource in each set of semi-persistent resources; CURRENT _ symbol is the symbol number of the target resource; the period is the period of the semi-persistent resource to which the target resource belongs; nrofHARQ-Processes is the number of HARQ Processes of the semi-persistent resource to which the target resource belongs; the offset _ sps is an initial value of an available HARQ process number configured for the semi-persistent resource to which the target resource belongs; floor (×) represents a down-rounding function; modulo is a modulo operation.

It should be noted that, when the grant type is configured for uplink, the specific obtaining manner of CURRENT _ symbol is according to the formula: (SFN × number OfSlotsPerFrame × number OfSymbolsPerSlot + slot number inter frame × number OfSymbolsPerSlot + symbol number in the slot).

When the authorization type two is configured for the uplink, the specific acquisition mode of CURRENT _ symbol is according to the formula: (SFN × number OfSlotsPerFrame × number OfSymbolsPerSlot + slot number in the frame × number OfSymbolsPerSlot + symbol number in the slot).

It should be further noted that, in the foregoing implementation manners of the first, second, and third, for multiple sets of semi-persistent resources with different cycle lengths, in a first cycle, if a first target resource in the first set of semi-persistent resources has a resource conflict with a resource in at least one other set of semi-persistent resources, an HARQ process number of a resource in a cycle corresponding to a set of semi-persistent resources with a longest cycle length in the at least one other set of semi-persistent resources is determined as a target HARQ process number of the first target resource in the first set of semi-persistent resources.

That is, when a resource collision occurs, the HARQ process number of the resource having the longest cycle of the semi-persistent resource allocation corresponding to the resource having the collision is used as a reference.

For example, as shown in fig. 2, when there are two types of semi-persistent resource configurations, the period length of semi-persistent resource configuration 1 is greater than the period length of semi-persistent resource configuration 2, and the HARQ process number cyclically used by the resource in semi-persistent resource configuration 1 is: 1. 2,3 and 4; the HARQ process number of resource recycling in the semi-persistent resource configuration 2 is: 5. 6,7 and 8; when a certain resource in the semi-persistent resource configuration 1 collides with a resource in the semi-persistent resource configuration 2, the HARQ process number corresponding to the resource in the semi-persistent resource configuration 1 is preferentially adopted for data transmission, for example, the slash filled box in fig. 2 indicates the resource with resource collision, and the HARQ process numbers respectively adopted by the corresponding resource with collision from left to right are as follows: 1. 2,4 and 1.

It should be further noted that, when the semi-persistent resources are: in autonomous uplink resource, HARQ configuration information available to the terminal in the first frequency domain typically includes only: the number of the HARQ process available for each set of semi-persistent resources in the first frequency domain range.

Specifically, under the condition that the semi-persistent resource is an autonomous uplink resource, the target HARQ process number is an HARQ process number autonomously selected from HARQ process numbers available for a first set of persistent resources, and is further an HARQ process number not used by the available HARQ process numbers, wherein the first set of semi-persistent resources is the semi-persistent resource to which the target resource belongs;

further, the data transmission method further includes:

informing the target HARQ process number to network equipment

The following describes a specific application scenario of the embodiment of the present invention in different cases.

Case one, the semi-persistent resource is downlink semi-persistent scheduling resource, and 1 HARQ process can be used in each period

Step S11, the network side issues configuration information of at least two sets of downlink semi-persistent scheduling resources to a BWP of a serving cell of the terminal, where the configuration information of the downlink semi-persistent scheduling resources mainly includes:

each set of downlink semi-persistent scheduling resource period;

for example, the period is 20ms, that is, every 20ms, the terminal has a usable downlink semi-persistent scheduling resource configured by the network side;

resource allocation information of each set of downlink semi-persistent scheduling resources in each period;

in the above description, the resource allocation information in each period has been specifically described, and is not described herein again.

Additionally, the network side or the protocol provides HARQ configuration information available for the terminal on BWP, where the available HARQ configuration information includes: the number of the HARQ process (namely HARQ process ID) available for each set of downlink semi-persistent scheduling resources on the BWP;

for example, the HARQ process ID available for the BWP is 0-8, the HARQ process ID available for one semi-persistent resource configuration on the BWP is [0,1,2,3], and the HARQ process ID available for another semi-persistent resource configuration is [4,5,6,7 ]; or, the HARQ process ID available for one resource on the BWP is [0,2,4,6], and the HARQ process ID available for another resource is [1,3,5,7 ]).

Step S12, when the network side sends an activation signaling (e.g., PDCCH activation command), indicating a starting position of the downlink semi-persistent scheduling resource in the time domain (e.g., SFN)_{start time}，slot_{start time})。

Step S13, the terminal calculates the time domain starting position of the downlink semi-persistent scheduling resource in each period according to the starting position of the downlink semi-persistent scheduling resource indicated by the network side and the formula one, that is:

(numberOfSlotsPerFrame×SFN+slot number in the frame)＝

step S14, the terminal obtains the HARQ process number of the target resource in each set of semi-persistent resources (i.e., in this case, each set of downlink semi-persistent scheduling resources) according to the configuration information in step S11;

specifically, when the number of the HARQ process available for each set of semi-persistent resources is a discrete natural number, the specific implementation manner of step S14 is as follows:

calculating the HARQ process number of the initial resource in each set of downlink semi-persistent scheduling resources;

the specific implementation mode is as follows:

firstly, according to the formula:

HARQ Process ID_start＝[floor(CURRENT_slot_{start time}×10/(numberOfSlotsPerFrame×periodicity))]and calculating the HARQ process number of the initial resource in each set of downlink semi-persistent scheduling resources by the modulo nrofHARQ-Processes + offset _ sps.

It should be noted that in this case, only one HARQ process can be used in each period, so different semi-persistent resources in the same period all use the same HARQ process.

Then determining the target HARQ process number of the target resource in each period of each set of semi-persistent resources according to a preset rule by taking the HARQ process number of the initial resource in each set of semi-persistent resources as a starting point; specifically, the preset rule is as follows: and circularly using according to the number of the available HARQ process of each set of semi-persistent resources.

It should be further noted that, when resource conflicts exist in the semi-persistent period for different downlink semi-persistent scheduling resource configurations on the same BWP, for multiple sets of semi-persistent resources with different cycle lengths, in the first cycle, if a resource conflict exists between a first target resource in the first set of semi-persistent resources and a resource in at least one other set of semi-persistent resources, the HARQ process number of the resource in the corresponding cycle of the set of semi-persistent resources with the longest cycle length in the at least one other set of semi-persistent resources is determined as the target HARQ process number of the first target resource in the first set of semi-persistent resources.

Specifically, when the number of the HARQ process available for each set of semi-persistent resources is a continuous natural number, the specific implementation manner of step S14 is as follows:

according to the formula:

the HARQ Process ID ═ floor (CURRENT _ slot × 10/(number of slot frame × periodic)) ] modulo nrofHARQ-Processes + offset _ sps, and the target HARQ Process number of the target resource in each set of semi-persistent resources is obtained.

Step S15, the network side transmits data on the corresponding downlink semi-persistent scheduling resource by using the corresponding HARQ process.

In case two, the semi-persistent resource is a downlink semi-persistent scheduling resource, and multiple HARQ processes (i.e. more than or equal to two HARQ processes) can be used in each period

Step S21, the network side issues configuration information of at least two sets of downlink semi-persistent scheduling resources to a BWP of a serving cell of the terminal, where the configuration information of the downlink semi-persistent scheduling resources mainly includes:

each set of downlink semi-persistent scheduling resource period;

for example, the period is 20ms, that is, every 20ms, the terminal has each downlink semi-persistent scheduling resource configured by the network side that can be used;

Additionally, the network side or the protocol provides HARQ configuration information available for the terminal on BWP, where the available HARQ configuration information includes at least one of the following information:

Then, the HARQ process number of the initial resource in each set of semi-persistent resources is used as a starting point, and the target HARQ process number of the target resource in each period of each set of semi-persistent resources is determined according to a preset rule; specifically, the preset rule is as follows: and circularly using according to the number of the available HARQ process of each resource in each set of semi-persistent resources.

That is, the numbers of the remaining HARQ processes are sequentially allocated in the order of the cycle number and the order of the resource number.

For example, "period ═ 10"; "nrofHARQ-Processes ═ 4"; "nrofHARQ-processpersperiod ═ 2". For example, a semi-persistent resource configuration configures 2 frequency domain resources or spatial domain resources or time domain resource locations in each period. Then: the "HARQ process number of the 1 st numbered resource of the 1 st period is 0"; the "HARQ process number of the 1 st numbered resource of the 2 nd period is 2"; the "HARQ process number of the 1 st numbered resource of the 3 rd period is 0"; the "HARQ process number of the 1 st numbered resource of the 4 th cycle is 2" and so on.
