Therefore, when the configured half When the continuous sending resource is not enough to transmit all the data to be transmitted of the UE, it can only wait until the next semi-continuous resource period, resulting in a delay in data transmission.

detailed description

In order to make the purpose, technical solutions and advantages of the disclosure more clear, the disclosure will be described in detail below with reference to the drawings and specific embodiments.

When explaining the embodiments of the present disclosure, first, some concepts used in the following description will be explained.

1. Semi-persistent resource allocation

In the current 5G system, user equipment (User Equipment, UE, also called terminal) can be configured with semi-persistent data transmission resources, mainly including:

Downlink semi-persistent scheduling (DL SPS, Downlink Semi-Persistent Scheduling)

Upstream configuration authorization type 1 (UL configuredd grant Type 1)

Upstream configuration authorization type 2 (UL configured grant type 2)

Autonomous Uplink (AUL)

The following describes several semi-persistent data transmission resources as follows.

In the DL SPS, periodic downlink resources are configured by the network side, and there is one downlink resource allocation per cycle. The network side activates or deactivates the use of the SPS resource through physical downlink control channel (Physical Downlink Control Channel, PDCCH) control signaling, and the PDCCH command indicates the location of the activated resource (eg, SFN _start _time (start system frame number) and slot _start _time (start slot number) is the starting position of the resource. The UE calculates the N-th resource location by formula 1:

Formula 1: (numberOfSlotsPerFrame × SFN + slot number in the frame) =

[(numberOfSlotsPerFrame × SFN _start _time + slot _start _time ) + N × periodicity × numberOfSlotsPerFrame / 10] modulo (1024 × numberOfSlotsPerFrame)

The DL SPS hybrid automatic repeat request (HARQ) process number for a specific slot (slot) is calculated by Equation 2:

Formula 2: HARQ Process ID = [floor (CURRENT_slot × 10 / (numberOfSlotsPerFrame × periodicity))] modulo nrofHARQ-Processes

Among them, CURRENT_slot is the slot number of the current resource, CURRENT_slot = [(SFN × numberOfSlotsPerFrame) + slot number in the frame (current system frame slot number)]; SFN (System Fram Number) is the current system frame number; numberOfSlotsPerFrame Number of time slots included in each system frame; periodicity is the SPS resource period configured for Radio Resource Control (RRC) messages; nrofHARQ-Processes is the number of HARQ processes of SPS resources configured for RRC messages.

UL Configured Grant Type 1 is configured by the network side with periodic uplink resources, and there is one uplink resource allocation per cycle. It does not require PDCCH order activation, and can be used after RRC configuration. The UE calculates the Nth resource location by formula 3:

Formula 3: [(SFN × numberOfSlotsPerFrame × numberOfSymbolsPerSlot) + (slot number in the frame × numberOfSymbolsPerSlot) + symbol number in the theslot] =

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

Among them, numberOfSymbolsPerSlot is the number of symbols (that is, orthogonal frequency division multiplexing (OFDM) symbols) for each time slot; timeDomainOffset is the resource offset in the time domain relative to SFN = 0 (for example, slot 1 ); N is the number of the resource; S is the number of the starting symbol (for example, for the position of slot 1, the starting symbol is OFDM symbol 1).

UL configuredd grant Type 1 The HARQ process number for a specific slot is calculated by Equation 4:

Formula 4. HARQ Process ID = [floor (CURRENT_symbol / periodicity)] modulo nrofHARQ-Processes

Among them, CURRENT_symbol is the symbol number corresponding to the current resource, CURRENT_symbol = (SFN × numberOfSlotsPerFrame × numberOfSymbolsPerSlot + slot number number in the frame × numberOfSymbolsPerSlot + symbol number number in the theslot (symbol number of the current slot)); numberOfSymbolsPerslot number of symbols

In UL configured grant Type 2, the network side configures periodic uplink resources, and each cycle has one uplink resource allocation. The network side activates or deactivates the use of the SPS resource through PDCCH control signaling. The PDCCH command indicates the location of the activated resource (eg, SFN _start _time (start system frame number) and slot _start _time (start slot number) and symbol _start _time (start symbol number)) is the starting position of the resource. The UE calculates the Nth resource location by formula 5:

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

[(SFN _start _time × numberOfSlotsPerFrame × numberOfSymbolsPerSlot + slot _start _time × numberOfSymbolsPerSlot + symbol _start _time ) + N × periodicity] modulo (1024 × numberOfSlotsPerFrame × numberOfSymbolsPerSlot)

UL Configured Grant Type 2 The HARQ process number for a specific time slot is calculated by the same calculation formula as UL Configured Grant Type 1.

AUL configures a bitmap (bitmap) resource allocation on the network side (for example, if one bit value is set to 1 in 40bit, the resource is allocated to the UE). The network side activates or deactivates the use of the AUL resource through PDCCH control signaling. The PDCCH command indicates the location of the activated resource (eg, SFN _start _time (start system frame number) and slot _start _time (start slot number) and symbol _start _time (start symbol number)) is the starting position of the resource. When the uplink data is sent, the UE autonomously selects a HARQ process from the HARQ process pool configured on the network side to send.

2. Introduction of Bandwidth Part (BWP)

In a 5G system, the UE may only support a relatively small operating bandwidth (such as 5MHz), while a cell on the network side will support a relatively large bandwidth (such as 100MHz), and the small bandwidth part of the large bandwidth UE operating Think of it as BWP. From the perspective of UE configuration, for different UE functions, BWP can be regarded as BWP under one cell. Multiple different BWPs use the same HARQ entity.

The network side can configure the UE to have one or more BWP, and can change the currently activated BWP of the UE through the BWP switching command (such as PDCCH indication information), that is, activate the new BWP and deactivate the currently activated BWP. Currently, the UE can only activate one BWP for one cell.

Additionally, the network side can configure a BWP inactivity timer (BWP-InactivityTimer) for an activated BWP. The UE starts after activating one BWP, and then after the timer expires, changes the activated BWP to the network configuration default BWP (Ie default BWP).

3. Background of the Industrial Internet of Things (IIOT) project

The RAN # 80 meeting agreed to the IIOT project. In the industrial environment, many applications (such as manufacturing, machine control, etc.) have high performance requirements, such as low latency, high reliability, and directional information transmission. The IIOT project hopes to provide a LAN-type communication service for such vertical industries through the 5G communication network to meet the communication needs of vertical industries.

In an industrial environment, most applications need to periodically send information, for example, periodically send information to a specific device so that it can perform specific operations. Compared with the dynamic resource scheduling method, the semi-persistent resource configuration method can reduce the delay of the UE sending the scheduling request. The current UE can only configure a very limited number of transmission resources in a semi-continuous transmission cycle (for example, 1 time domain transmission resources), so when the transmission resources are not enough to transmit all the data to be transmitted by the UE, only Waiting for the next half-sustained resource cycle causes a delay in data transmission.

In the related art, one BWP is configured with only one semi-persistent resource, and a serving cell can only activate one semi-persistent resource at any time. When the network side configures multiple different semi-persistent resources (eg, SPS) on a BWP of the serving cell, how to allocate multiple activated semi-persistent resources on a BWP becomes a problem that needs to be solved, and the present disclosure This problem is solved.

As shown in FIG. 1, some embodiments of the present disclosure provide a data transmission method, which is applied to a terminal and includes:

Step 101: Acquire resource configuration information in the first frequency domain, where the resource configuration information includes at least two sets of semi-persistent resource configuration information;

It should be noted that the first frequency domain range refers to a BWP, that is, there are at least two sets of semi-persistent resource configuration information on the same BWP; the at least two sets of semi-persistent resources refer to at least two semi-persistent resources Resource allocation, that is, each set of semi-persistent resources actually refers to each semi-persistent resource allocation.

Step 102: Acquire the target hybrid automatic retransmission request HARQ process number of the target resource in each set of semi-persistent resources according to the resource configuration information;

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

Step 103: At the location of the target resource, a HARQ process corresponding to the target HARQ process number is used for data transmission.

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

Semi-persistent resources include: four types: downlink semi-persistent scheduling resources, uplink configuration authorization type one, uplink configuration authorization type two, and autonomous uplink resources; each type of semi-persistent resource corresponds to different resource configuration information. The following describes the resource configuration information from different resource types as follows.

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

A11. The period of each set of semi-persistent resources, for example, the period is 20 ms, that is, the terminal has available resources configured on the network side every 20 ms.

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;

Specifically, the resource allocation information of each set of semi-persistent resources includes at least one of the following information:

B1, at least one frequency domain resource allocation information;

Specifically, the frequency domain resource allocation information includes at least one of the following information:

Wherein, the reference signal identifier includes at least one of the following information:

The synchronization signal block identification and channel state information refer to the signal identification.

B3. At least one time domain resource allocation information;

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

It should also be noted that when the semi-persistent resources are: downlink semi-persistent scheduling resources, uplink configuration authorization type 1, uplink configuration authorization type 2, or autonomous uplink resources, the resource configuration information further includes: the terminal is in the first frequency domain range Available HARQ configuration information.

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

C1, the HARQ process number available for each set of semi-persistent resources on the first frequency domain range;

It should be noted that the number of HARQ processes available for each set of semi-persistent resources can be a continuous natural number. For example, the number of HARQ processes available for one set of semi-persistent resources is: 1, 2, 3, and 4, and the other set of semi-persistent resources is available. The number of HARQ processes is: 5, 6, 7, and 8; the number of HARQ processes available for each set of semi-persistent resources can be a discrete natural number. For example, the number of HARQ processes available for a set of semi-persistent resources is: 1, 3, 5, and 7. Another set of HARQ process numbers available for semi-persistent resources are: 2, 4, 6, and 8.

C2. The number of HARQ processes available in each cycle of each set of semi-persistent resources;

For example, the number of HARQ processes available in each cycle of a set of semi-persistent resources is 2, and the number of HARQ processes available in each cycle of another set of semi-persistent resources is 4.

In the following, the implementation of step 102 is specifically described as follows in different situations.

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

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

Then the specific implementation of step 102 is:

Obtain the HARQ process number of the starting resource in each set of semi-persistent resources;

Taking the HARQ process number of the starting resource in each set of semi-persistent resources as a starting point, the target HARQ process number of the target resource in each cycle of each set of semi-persistent resources is determined according to preset rules.

Further, in the case where the semi-persistent resources include: downlink semi-persistent scheduling resources, the HARQ process number of acquiring the starting 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))] modulo (nrofHARQ-Processes / nrofHARQ-ProcessesPerPeriod) + offset_sps to obtain the HARQ process number of the starting resource in each set of semi-persistent resources;

Among them, HARQ Process ID _start is the HARQ process number of the starting resource in each set of semi-persistent resources; CURRENT_slot _start _time is the slot number of the starting resource; numberOfSlotsPerFrame is the number of slots contained in each system frame; periodicity is the starting resource The period of the semi-persistent resource to which it belongs; nrofHARQ-Processes is the number of HARQ processes of the semi-persistent resource to which the starting resource belongs; nrofHARQ-ProcessesPerPeriod is the number of HARQ processes available per cycle of the semi-persistent resource to which the target resource belongs; offset_sps is The starting value of the available HARQ process number of the semi-persistent resource to which the starting resource belongs; floor (*) indicates the downward rounding function; modulo is the modulo operation.

It should be noted that the specific acquisition method of CURRENT_slot _start _time is obtained according to the formula: numberOfSlotsPerFrame × SFN _start _time + slot _start _time .

It should be noted that in this case, each set of semi-persistent resources may be one or more HARQ processes available in each cycle. When each set of semi-persistent resources is available in each cycle, HARQ processes When it is one, the value of nrofHARQ-ProcessesPerPeriod 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, when the semi-persistent resources include: uplink configuration authorization type 1 or uplink configuration authorization type 2, the HARQ process number of acquiring the starting resource in each set of semi-persistent resources includes:

HARQ Process ID _start = [floor (CURRENT_symbol _start _time / periodicity)] modulo (nrofHARQ-Processes / nrofHARQ-ProcessesPerPeriod) + offset_sps to obtain the HARQ process number of the starting resource in each set of semi-persistent resources;

Among them, HARQ Process ID _start is the HARQ process number of the starting resource in each set of semi-persistent resources; CURRENT_symbol _start _time is the symbol number of the starting resource; periodicity is the period of the semi-persistent resource to which the starting resource belongs; nrofHARQ-Processes is from The number of HARQ processes of the semi-persistent resources to which the start resource belongs; nrofHARQ-ProcessesPerPeriod is the number of HARQ processes available per cycle of the semi-persistent resources to which the target resource belongs; offset_sps is the available HARQ process number of the semi-persistent resources to which the start resource belongs The initial value of; floor (*) means downward rounding function; modulo is modulo operation.

It should be noted that when the authorization type 1 is configured for the uplink, the specific acquisition method of CURRENT_symbol _start _time is obtained according to the formula: (timeDomainOffset × numberOfSymbolsPerSlot + S).

When the authorization type 2 is configured for the uplink, the specific acquisition method of CURRENT_symbol _start _time is obtained according to the formula: (SFN _start _time × numberOfSlotsPerFrame × numberOfSymbolsPerSlot + slot _start _time × numberOfSymbolsPerSlot + symbol _start _time ).

It should be noted that in this case, each set of semi-persistent resources may be one or more HARQ processes available in each cycle. When each set of semi-persistent resources is available in each cycle, HARQ processes When it is one, the value of nrofHARQ-ProcessesPerPeriod is 1, that is, the formula becomes:

HARQ Process ID _start = [floor (CURRENT_symbol _start _time / periodicity)] modulo nrofHARQ-Processes + offset_sps.

Specifically, in the above case, if each set of semi-persistent resources has an available HARQ process in each cycle, the preset rule includes: recycling according to the available HARQ process number of each set of semi-persistent resources. For example, the number of available HARQ processes for each set of semi-persistent resources is 1, 3, and 5, in this case, the first cycle uses 1, the second cycle uses 3, the third cycle uses 5, the subsequent The cycle is in the order of 1, 3, and 5.

If each set of semi-persistent resources has at least two HARQ processes available in each cycle, the preset rule includes: recycling according to the available HARQ process number of each resource in each set of semi-persistent resources. For example, the available HARQ process numbers for each set of semi-persistent resources are 2, 4, 6, and 8. In this case, the first cycle uses 2 and 4, the second cycle uses 6 and 8, and subsequent cycles Recycle in the order of 2 and 4 and 6 and 8.

2. In the case of semi-persistent resources including: downlink semi-persistent scheduling resources, if each set of semi-persistent resources has an available HARQ process in each cycle, and the number of HARQ processes available for each set of semi-persistent resources is a continuous natural number , The specific implementation of step 102 is:

According to the following preset formula:

HARQ Process ID = [floor (CURRENT_slot × 10 / (numberOfSlotsPerFrame × periodicity))] modulo nrofHARQ-Processes + offset_sps, to obtain the target HARQ process number of the target resource in each set of semi-persistent resources;

Among them, HARQ Process ID is the target HARQ process number of the target resource in each set of semi-persistent resources; CURRENT_slot is the slot number of the target resource; numberOfSlotsPerFrame is the number of slots contained in each system frame; periodicity is the target The period of the semi-persistent resource to which the resource belongs; nrofHARQ-Processes is the number of HARQ processes of the semi-persistent resource to which the target resource belongs; offset_sps is the starting value of the available HARQ process number configured for the semi-persistent resource to which the target resource belongs; (*) Indicates downward rounding function; modulo is modulo operation.

It should be noted that the specific acquisition method of CURRENT_slot is obtained according to the formula: CURRENT_slot = (SFN × numberOfSlotsPerFrame) + slot number in the frame.

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

3. In the case of semi-persistent resources including: uplink configuration authorization type 1 or uplink configuration authorization type 2, if each set of semi-persistent resources has an available HARQ process in each cycle, and each set of semi-persistent resources is available HARQ The process number is a continuous natural number, and the specific implementation of step 102 is:

According to the following preset formula:

HARQProcessID = [floor (CURRENT_symbol / periodicity)] modulo HARQ-Processes + offset_sps, to obtain the target HARQ process number of the target resource in each set of semi-persistent resources;

Among them, 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; periodicity 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; offset_sps is the starting value of the available HARQ process number configured for the semi-persistent resource to which the target resource belongs; floor (*) indicates the downward rounding function; modulo is to take Modular operation.

It should be noted that when the authorization type 1 is configured for uplink, the specific acquisition method of CURRENT_symbol is obtained according to the formula: (SFN × numberOfSlotsPerFrame × numberOfSymbolsPerSlot + slot number in the frame × numberOfSymbolsPerSlot + symbol number number in the slot)

When the authorization type 2 is configured for the uplink, the specific acquisition method of CURRENT_symbol is obtained according to the formula: (SFN × numberOfSlotsPerFrame × numberOfSymbolsPerSlot + slot number in the frame × numberOfSymbolsPerSlot + symbol number number in the the slot).

It should also be noted that, in the first, second, and third implementation manners above, for multiple sets of semi-persistent resources with different cycle lengths, in the first cycle, if the first target resource in the first set of semi-persistent resources is the same as If there is a resource conflict in the resources of at least one other set of semi-persistent resources, the HARQ process number of the resource of the set of semi-persistent resources with the longest period in the other at least one set of semi-persistent resources in its corresponding period is determined as The target HARQ process number of the first target resource in the first set of semi-persistent resources is described.

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

For example, as shown in FIG. 2, when there are two types of semi-persistent resource configuration, 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 of resource recycling in semi-persistent resource configuration 1 The numbers are: 1, 2, 3, 4; the number of HARQ processes used for resource recycling in semi-persistent resource configuration 2 are: 5, 6, 7, 8; when one of the resources in semi-persistent resource configuration 1 and semi-persistent resources When the resource in configuration 2 collides, the HARQ process number corresponding to the resource in semi-persistent resource configuration 1 is preferred for data transmission. As shown in Figure 2, the slash-filled box indicates the resource in which the resource collided, corresponding from left to right The HARQ process numbers adopted by the resources that collided are: 1, 2, 4, and 1, respectively.

It should also be noted that when the semi-persistent resources are: autonomous uplink resources, the HARQ configuration information available on the terminal in the first frequency domain range usually only includes: HARQs available for each set of semi-persistent resources in the first frequency domain range Process number.

Specifically, in the case where the semi-persistent resource is an autonomous uplink resource, the target HARQ process number is a HARQ process number independently selected from the HARQ process numbers available for the first set of persistent resources, and further, the available HARQ process numbers The HARQ process number that is not used, where the first set of semi-persistent resources is the semi-persistent resources to which the target resource belongs;

Further, the data transmission method further includes:

Notify the network device of the target HARQ process number

The following describes the specific application scenarios of some embodiments of the present disclosure in different situations as follows.

Case 1: The semi-persistent resource is a downlink semi-persistent scheduling resource, and there is 1 HARQ process available in each cycle

Step S11: The network side delivers at least two sets of downlink semi-persistent scheduling resource configuration information to a BWP of a serving cell of the terminal. The downlink semi-persistent scheduling resource configuration information mainly includes:

Each set of downlink semi-persistent scheduling resources;

For example, the period is 20 ms, that is, every 20 ms, the terminal has available downlink semi-persistent scheduling resources configured by the network side;

Resource allocation information of each set of downlink semi-persistent scheduling resources in each cycle;

In the above description, the resource allocation information in each cycle has been described in detail, and will not be repeated here.

In addition, the network side or the protocol stipulates the HARQ configuration information available to the terminal on the BWP. The available HARQ configuration information includes: the HARQ process ID (that is, 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 to 8, the HARQ process ID available for one semi-persistent resource configuration on the BWP is [0,1,2,3], and the other HARQ process ID available for the 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 (for example, a PDCCH activation command), it indicates the starting position of the downlink semi-persistent scheduling resource in the time domain (for example, 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 cycle according to the starting position of the downlink semi-persistent scheduling resource indicated by the network side and the above formula 1, namely:

(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 (that is, in this case, each set of downlink semi-persistent scheduling resources) according to the configuration information in step S11;

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

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

The specific implementation method is:

First, according to the formula:

HARQ Process ID _start = [floor (CURRENT_slot _start _time × 10 / (numberOfSlotsPerFrame × periodicity))] modulo nrofHARQ-Processes + offset_sps, calculate the HARQ process number of the starting resource in each set of downlink semi-persistent scheduling resources.

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

Then, according to the HARQ process number of the starting resource in each set of semi-persistent resources as a starting point, and according to preset rules, determine the target HARQ process number of the target resource in each cycle of each set of semi-persistent resources; specifically, the Let the rule be: recycle according to the available HARQ process number of each set of semi-persistent resources.

It should also be noted that, when different downlink semi-persistent scheduling resources on the same BWP are configured with resource conflicts in the semi-persistent period, for multiple sets of semi-persistent resources with different cycle lengths, within the first period, if the first set If there is a resource conflict between the first target resource in the semi-persistent resources and the resources in at least one other set of semi-persistent resources, the set of semi-persistent resources with the longest cycle length among the other at least one set of semi-persistent resources is within its corresponding period The HARQ process number of the resource 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 HARQ processes available for each set of semi-persistent resources is a continuous natural number, the specific implementation of step S14 is:

According to the formula:

HARQ Process ID = [floor (CURRENT_slot × 10 / (numberOfSlotsPerFrame × periodicity))] modulo nrofHARQ-Processes + offset_sps, to obtain the target HARQ process number of the target resource in each set of semi-persistent resources.

Step S15: The network side uses the corresponding HARQ process to send data on the corresponding downlink semi-persistent scheduling resource.

Case 2: The semi-persistent resource is a downlink semi-persistent scheduling resource, and multiple HARQ processes (that is, HARQ processes greater than or equal to two) can be used in each cycle

The available HARQ process number (ie HARQ process ID) of each set of downlink semi-persistent scheduling resources on the BWP;

The number of HARQ processes available in each cycle of each set of downlink semi-persistent scheduling resources;

For example, the network configuration can use 2 HARQ processes per cycle.

Step S22: When the network side sends an activation signaling (for example, a PDCCH activation command), it indicates the starting position of the downlink semi-persistent scheduling resource in the time domain (for example, SFN _start _time , slot _start _time ).

That is, in the order of cycle numbering and resource numbering, the remaining HARQ process numbers are allocated in order.

For example, "periodicity = 10"; "nrofHARQ-Processes = 4"; "nrofHARQ-ProcessesPerPeriod = 2". For example, in a semi-persistent resource configuration, two frequency-domain resources, spatial-domain resources, or time-domain resource locations are configured in each cycle. Then: "HARQ process number = 0" for the first numbered resource in the first cycle; "HARQ process number = 2" for the first numbered resource in the second cycle; the first one in the third cycle "HARQ process number = 0" for the numbered resource; "HARQ process number = 2" for the first numbered resource in the fourth cycle, and so on.
