The wireless communication system may be a 5G system, an Evolved Long Term Evolution (lte) system, or a subsequent lte communication system.

Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal 11 and a network device 12, where the terminal 11 may be a User Equipment (UE) or other terminal-side devices, for example: it should be noted that, in the embodiment of the present invention, a specific type of the terminal 11 is not limited, and the terminal may be a terminal-side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a laptop Computer (laptop Computer), a Personal digital assistant (PDA for short), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device).

It should be noted that, in the embodiment of the present invention, only the 5G base station is taken as an example, but the specific type of the network device is not limited.

Referring to fig. 2, fig. 2 is a flowchart of a UCI transmission method according to an embodiment of the present invention, applied to a terminal, and as shown in fig. 2, the method includes the following steps:

step 201, receiving DCI, where the DCI includes a PUCCH resource indication.

The receiving DCI may be a terminal receiving a Physical Downlink Control Channel (PDCCH) and obtaining the DCI by analyzing the PDCCH.

In this embodiment of the present invention, the PUCCH Resource indication may be an acknowledgement/negative acknowledgement Indicator (ARI), that is, the PUCCH Resource may be indicated by an ARI field in DCI. Of course, the embodiment of the present invention does not limit the PUCCH resources indicated by the ARI, for example: the PUCCH resources may also be indicated by other fields in the DCI, or redefined DCI, and newly added fields in the DCI.

Step 202, determining a PUCCH resource group indicated by the PUCCH resource indication, where the PUCCH resource group includes multiple PUCCH resources, or the PUCCH resource group is one PUCCH resource group selected from at least one first PUCCH resource group and at least one second PUCCH resource group according to the PUCCH resource indication, where the first PUCCH resource group includes multiple PUCCH resources, and the second PUCCH resource group includes one PUCCH resource.

In this embodiment of the present invention, the PUCCH resource indication may indicate an index of the PUCCH resource group, so that the terminal may determine the PUCCH resource group indicated by the PUCCH resource indication through the index. The different indexes correspond to different PUCCH resource groups, and the number of PUCCH resources included in the different PUCCH resource groups may be the same, for example: all are n PUCCH resources, wherein n is an integer greater than or equal to 2; or PUCCH resource groups with different numbers of PUCCH resources exist in the plurality of PUCCH resource groups, for example: some PUCCH resource groups have only one PUCCH resource, and other PUCCH resource groups include two PUCCH resources, or some PUCCH resource groups include three, four PUCCH resources, and so on.

Of course, in the embodiment of the present invention, the PUCCH resource indication is not limited to be an index of the PUCCH resource group, and in some embodiments, the PUCCH resource indication may implicitly indicate the PUCCH resource group, for example: the PUCCH resource indication may indicate an index or an identifier of one PUCCH resource in the PUCCH resource group, and the terminal determines one or more PUCCH resources corresponding to the PUCCH resource indication through the PUCCH resource, thereby obtaining a PUCCH resource group including the PUCCH resource indicated by the PUCCH resource indication and the PUCCH resource corresponding to the PUCCH resource.

In addition, in this embodiment of the present invention, the PUCCH resource group includes a plurality of PUCCH resources, where the PUCCH resource indication indicates a plurality of PUCCH resources each time, for example: n PUCCH resources are indicated at a time, where n is an integer greater than or equal to 2. Of course, each time, a plurality of PUCCH resources are indicated, and the number of PUCCH resources indicated by each time is not limited to be the same, for example: some scenarios may indicate 2 PUCCH resources, while other scenarios may indicate 3 PUCCH resources, i.e. the indicated number of PUCCH resources may be dynamically adjusted.

In this way, a plurality of PUCCH resources can be indicated through one DCI, and the effect of indicating the PUCCH resources is improved.

In addition, the first PUCCH resource group may be a PUCCH resource group including a plurality of PUCCH resources, for example: the at least one first PUCCH resource group includes a PUCCH resource group a, a PUCCH resource group b, and a PUCCH resource group c, where the PUCCH resource group a includes 2 PUCCH resources, the PUCCH resource group b includes 3 PUCCH resources, and the PUCCH resource group c includes 4 PUCCH resources, that is, the PUCCH resource group a, the PUCCH resource group b, and the PUCCH resource group c are all first PUCCH resource groups.

And the second PUCCH resource group may be one or more PUCCH resource groups, for example: the at least one second PUCCH resource group includes a PUCCH resource group d, a PUCCH resource group e, and a PUCCH resource group f, where the PUCCH resource group d, the PUCCH resource group e, and the PUCCH resource group f all include 1 PUCCH resource, but the PUCCH resources included in the three PUCCH resource groups are different, that is, the PUCCH resource group d, the PUCCH resource group e, and the PUCCH resource group f are all second PUCCH resource groups.

The PUCCH resource group is one PUCCH resource group selected from at least one first PUCCH resource group and at least one second PUCCH resource group according to the PUCCH resource indication, and it is understood that the PUCCH resource indication indicates one PUCCH resource group among a plurality of PUCCH resource groups (including one or more first PUCCH resource groups and one or more second PUCCH resource groups).

In this way, the terminal can receive the DCI from the network device and determine whether to use a plurality of PUCCH resources or one PUCCH resource according to the DCI, thereby improving the effect of indicating the PUCCH resource. For example: the network device may indicate one or more PUCCH resources to the terminal through the PUCCH resource indication according to a requirement. For example: more PUCCH resources may be indicated when the channel is busy or the network load is large, and less PUCCH resources may be indicated when the channel is idle or the network load is small.

And 203, transmitting the UCI through the PUCCH resources included in the PUCCH resource group.

The step may be that, in a case where the PUCCH resource group includes a plurality of PUCCH resources, UCI is transmitted on the plurality of PUCCH resources, respectively, and the content of UCI indications transmitted on the plurality of PUCCH resources, respectively, may be the same. Therefore, a plurality of UCIs are sent in a plurality of PUCCH resources, the situation that the channel is blocked can be avoided, and the success rate of UCI feedback can be improved. For example: the UCI is HARQ-ACK, and the success rate of terminal feedback can be increased by feeding back a plurality of HARQ-ACKs.

It should be noted that, in the embodiment of the present invention, the UCI is not limited to HARQ-ACK, for example: the UCI may also be the rest of control information that the terminal needs to feed back to the network device.

In addition, in step 203, when the PUCCH resource group includes one PUCCH resource, UCI may be transmitted in the one PUCCH resource. For example: when the channel is idle or the network load is small, UCI is transmitted through one PUCCH resource.

In the embodiment of the present invention, the PUCCH resources can be flexibly indicated through the above steps, so as to improve the indicating effect of the PUCCH resources, and also improve the success rate of the terminal for feeding back the UCI, because some terminals have a lower success rate for feeding back the UCI, for example: in a situation that a channel is busy or a network load is greater, a plurality of PUCCH resources can be indicated, so that the success rate of transmitting UCI by the terminal is improved.

As an optional implementation manner, the determining the PUCCH resource group indicated by the PUCCH resource indication includes:

and determining the PUCCH resource groups indicated by the PUCCH resource indications in the resource mapping relation according to the resource mapping relation, wherein the resource mapping relation comprises the mapping relation between a plurality of PUCCH resource indications and PUCCH resource groups.

The resource mapping relationship may be configured in advance, or the network device sends the resource mapping relationship to the terminal in advance, or the resource mapping relationship is defined in advance in a protocol.

The resource mapping relationship includes a plurality of different PUCCH resource indications, where each PUCCH resource indication has a different value, for example: taking 3 bits as an example, the resource mapping relationship may include 8 PUCCH resource indication values, for example: 000. 001, 010, 011, 100, 101, 110 and 111, wherein each value corresponds to different PUCCH resource groups. Each PUCCH resource group includes different PUCCH resources.

The terminal can quickly and accurately determine the PUCCH resource groups indicated by the PUCCH resource indication through the resource mapping relation.

In the above embodiment, in the resource mapping relationship, the number of PUCCH resources included in different PUCCH resource groups may be the same or different.

Optionally, each resource group in the resource mapping relationship includes n PUCCH resources, where n is an integer greater than or equal to 2.

The n may be configured in advance, or the protocol is defined in advance, and of course, may also be configured by dynamic signaling.

In this embodiment, it may be implemented that each PUCCH resource indication indicates n PUCCH resources, for example: taking n as 2 as an example, the resource mapping relationship may be as shown in table 1:

table 1:

the configuration of 8n resources for the PUCCH Resource Set (RESET) can be realized through the table, and each PUCCH Resource indicates (for example: ARI) resources (n ≧ 2) corresponding to n PUCCHs. The PUCCH RESET here may be PUCCH RESET 1, PUCCH RESET2, or PUCCH RESET3, allowing PUCCH RESET to configure 8n resources.

In this embodiment, each PUCCH resource indicates that n PUCCH resources are configured, so that the success rate of UCI transmission can be increased. In addition, the n can be flexibly configured, for example: it may be pre-configured by the network device, or pre-defined in the protocol, etc.

Optionally, the PUCCH resource groups in the resource mapping relationship include the at least one first PUCCH resource group and the at least one second PUCCH resource group.

In this way, the PUCCH resource groups indicated by the PUCCH resource indication can be determined according to the mapping relationship, and the number of PUCCH resources indicated by different PUCCH resource indications (e.g., ARI) may be the same or different. Therefore, the network equipment can dynamically adjust the number of PUCCH resources for transmitting UCI by the terminal through the PUCCH by utilizing the PUCCH resource indication according to the occupation condition of the channel, so as to improve the success rate of the UCI improvement of the terminal.

For example: when the channel is busy or the load of the network is large, more PUCCH resources are indicated; and when the channel is idle or the load of the network is small, less PUCCH resources are indicated.

Specifically, in this embodiment, the resource mapping relationship may be added, for example: adding a PUCCH Resource indication (PUCCH _ Resource _ indicator) (e.g. ARI) to PUCCH Resource (PUCCH _ Resource) mapping table, wherein for the value corresponding to the jth PUCCH _ Resource _ indicator, mapping is carried out to M of M PUCCH Resource identifications (PUCCH-Resource Id) in a Resource List (Resource List)_jAnd one PUCCH-Resource Id.

In the following, the above embodiment is illustrated in table 2, and assuming that the PUCCH resource number included in the resource List (resource List) is {1,3,5,7,9,11,21,23,45, … }, the resource mapping relationship may be as shown in table 2:

table 2:

thus, through the resource mapping relationship shown in the above table, it may be achieved that a plurality of PUCCH resources may be indicated in some scenarios indicated by the PUCCH resource, or one PUCCH resource may be indicated in another scenario, or different numbers of PUCCH resources may be indicated in different scenarios, for example: the number of PUCCHs resources corresponding to different PUCCH resource indicators may be different.

Optionally, the resource mapping relationship includes multiple PUCCH resource groups with different numbers of PUCCH resources, and different PUCCH resource groups correspond to different PUCCH resource indications.

For example: the PUCCH resource indicators of 000, 001, 010, and 011 respectively correspond to PUCCH resource groups with 4 PUCCH resources of 1, the PUCCH resource indicators of 100 and 101 respectively correspond to PUCCH resource groups with 2 PUCCH resources of 2, and the PUCCH resource indicators of 110 and 111 respectively correspond to PUCCH resource groups with 2 PUCCH resources of 4.

Specifically, in a first scenario, the PUCCH resource group indicated by the PUCCH resource indication in the DCI includes h PUCCH resources;

in a second scenario, a PUCCH resource group indicated by the PUCCH resource indication in the DCI includes j PUCCH resources;

wherein h is an integer greater than j, and j is an integer greater than or equal to 1.

The first scenario and the second scenario may be scenarios determined by the network device, and certainly may also be scenarios defined in a protocol, which is not limited in this respect. For example: the PUCCH in the first scenario is busy than the PUCCH in the second scenario, or the network load in the first scenario is greater than the network load in the second scenario, and so on.

By indicating different numbers of PUCCH resources, the PUCCH resources can be saved on the premise of ensuring that the terminal improves the success rate of UCI.

As an optional implementation manner, the PUCCH resource group indicated by the PUCCH resource indication includes:

the PUCCH resource group implicitly indicated by the PUCCH resource indication comprises:

the PUCCH resource indication corresponds to a first PUCCH resource;

and the first PUCCH resource is matched with a second PUCCH resource.

The first PUCCH resource may be one or more PUCCH resources, and the second PUCCH resource may also be one or more PUCCH resources. In addition, the second PUCCH resource matched with the first PUCCH resource may be a configuration parameter of the first PUCCH resource and a configuration parameter of the second PUCCH resource, where the configuration parameter has a certain relationship, for example: adjacent time domains, or adjacent frequency domains, or identical frequency domains, but adjacent time domains, etc.

In this embodiment, the implicit indication of the PUCCH resource may be implemented to indicate a plurality of PUCCH resources, so that the overhead of DCI may be saved.

Optionally, the time domain resource occupied by the second PUCCH resource is adjacent to the time domain resource occupied by the first PUCCH resource; or

The time domain resource occupied by the second PUCCH resource is overlapped with the time domain resource occupied by the first PUCCH resource.

The time domain resource adjacency may be that the time domain resource occupied by the second PUCCH resource is consecutive to the time domain resource occupied by the first PUCCH resource in the time domain, or that the two time domain resources are separated from a specific time domain resource unit, for example: distance x slots, or distance k symbols, etc.

Because the time domain resource occupied by the second PUCCH resource is adjacent to the time domain resource occupied by the first PUCCH resource, the UCI can be improved on the adjacent time domain resource, and the transmission efficiency of the UCI is improved.

In addition, the overlapping may be that the time domain resource occupied by the second PUCCH resource is completely overlapped or partially overlapped with the time domain resource occupied by the first PUCCH resource, so that all or part of UCI can be transmitted within the same time, and the UCI transmission efficiency can be further improved.

Optionally, the parameter configuration of the second PUCCH resource is the same as the parameter configuration of the first PUCCH resource.

Wherein the parameter configuration may include, but is not limited to, at least one of:

PUCCH Format (PUCCH Format), Starting symbol (Starting symbol), Number of symbols in slot (Number of symbols in a slot), Index of Starting PRB (Index for identifying Starting PRB), Number of PRBs (Number of PRBs), Starting Frequency hopping information (energy Frequency hopping), and Frequency resource of second hop (Frequency resource of 2)^ndhop if frequency)。

Preferably, the parameter configuration may be the same for all configuration parameters, or may be partially the same, which is not limited to this.

It should be noted that the configuration parameters of the PUCCH resources may be configured in advance, for example: and receiving the configuration of each PUCCH resource transmitted by the network equipment, the configuration predefined in a protocol, and the like.

In this embodiment, since the parameter configuration of the second PUCCH resource is the same as the parameter configuration of the first PUCCH resource, it can be ensured that UCI transmitted multiple times is transmitted using PUCCH resources with the same parameter, and thus, network devices can more easily and successfully receive UCI.

Optionally, a time domain interval between the time domain resource occupied by the second PUCCH resource and the time domain resource occupied by the first PUCCH resource is equal to x time domain resource units, where x is an integer greater than or equal to 1; or

And the frequency domain interval between the frequency domain resource occupied by the second PUCCH resource and the frequency domain resource occupied by the first PUCCH resource is more than y frequency domain resource units, wherein y is an integer which is more than or equal to 1.

The time domain resource unit may be a slot (slot), which is not limited, for example: but also subframes, or symbols. In addition, the x can be predefined by network configuration, dynamic signaling or protocol.

Therefore, UCI can be transmitted on a plurality of PUCCH resources with the time domain interval equal to x time domain resource units, and the success rate of UCI transmission can be improved.

In addition, the time domain resource unit may be PRB or MHz, and the y may be a fixed value or network configuration or dynamic signaling, or predefined by a protocol. In this embodiment, UCI can be transmitted on a plurality of PUCCH resources whose frequency domain interval is greater than y frequency domain resource units, so that the success rate of UCI transmission can be improved.

In addition, the frequency domain interval between the frequency domain resource occupied by the second PUCCH resource and the frequency domain resource occupied by the first PUCCH resource may be greater than y frequency domain resource units, except for PUCCH resources that are separated from PUCCH resources by y time domain resource units in the frequency domain.

It should be noted that the various alternative embodiments described herein may be implemented in combination with each other or separately. For example: the second PUCCH resource is adjacent to or overlapped with the first PUCCH resource time domain resource, and at least one of the following conditions is satisfied:

the parameter configuration of the second PUCCH resource is the same as the parameter configuration of the first PUCCH resource;

the frequency domain interval between the frequency domain resource occupied by the second PUCCH resource and the frequency domain resource occupied by the first PUCCH resource is larger than y frequency domain resource units.

Various embodiments provided by the embodiments of the present invention are illustrated below with PUCCH resource indication as ARI:

the resource flow of the terminal for determining the PUCCH is as follows:

firstly, a terminal configures resources of a PUCCH by receiving high-level signaling from a network;

secondly, the terminal receives the PDCCH and obtains DCI information through the PDCCH;

thirdly, the terminal knows which group of PUCCH resources should be used through ARI information in the DCI, and the group of PUCCH resources comprises 1 or more PUCCH resources;

and fourthly, the terminal transmits UCI on the set of PUCCH resources.

The following examples may exist for the third step:

example 1:

in this embodiment, the indication of each ARI corresponds to resources of n PUCCHs.

In this embodiment, a modification of the present protocol standard may be implemented to allow PUCCHRESET to configure 8n resources for PUCCH RESET 1/2/3 (the present Rel-15NR protocol only allows 8 resources to be configured), with each indication of ARI corresponding to n PUCCH resources (n ≧ 2). For example, see table 1 when n is 2, which is not described herein.

Example 2:

in this embodiment, a corresponding PUCCH Resource is configured for each indication of ARI.

A plurality of PUCCH resources are appointed for each ARI indication, and the number of the PUCCH resources indicated by different ARIs can be the same or different.

This has the advantage that the base station can dynamically modulate the number of resources of the terminal transmitting UCI through PUCCH according to the occupancy of the channel by ARI.

When the channel is busy or the load of the network is large, more PUCCH resources are indicated by ARI;

when the channel is idle or the network load is small, the ARI indicates less PUCCH resources.

In this embodiment, the modification to the existing protocol signaling may be based as follows:

adding a PUCCH _ resource _ indicator (namely ARI) to PUCCH _ resource mapping table, and mapping M of M PUCCH-resource IDs in a resource List for a value corresponding to a jth PUCCH _ resource _ indicator_jOne PUCCH-resource id

For example: the PUCCH Resource included in the Resource List has a number {1,3,5,7,9,11,21,23,45, … }, and the mapping shown in table 2 is defined, which is not described herein.

Wherein, the number of PUCCH resources corresponding to different PUCCH Resource indicators (i.e. ARIs) may be different.

Example 3:

in this embodiment, the terminal implicitly corresponds to multiple PUCCH resources according to the value of the ARI.

The method comprises the following steps:

the terminal can find the Resource of a second PUCCH of the adjacent time domain resources according to the first PUCCH Resource corresponding to the ARI value. Here, adjacent refers to:

the method comprises the following steps: all parameter configurations of the second and first PUCCH resources are the same, but the second PUCCH Resource is one slot later than the first PUCCH Resource (or x slots, x may be notified according to network configuration or dynamic signaling);

the method 2 comprises the following steps: all parameter configurations of the second and first PUCCH resources are the same, except that the second PUCCH Resource is separated from the first PUCCH Resource by y PRBs (or y MHz) in the frequency domain, where y may be a fixed value or network configuration or dynamic signaling.

Generally, in NR-unlicensed (NR-U), y may be taken to be 20MHz, because the busy-idle detection of the channel is in units of 20 MHz.

In the embodiment of the present invention, the terminal knows which set of PUCCH resources should be used through ARI information in the DCI, where the set of PUCCH resources includes 1 or more PUCCH resources.

Therefore, the ARI field in the DCI is used for expanding the original PUCCH resources, and the terminal can avoid the situation that the channel is blocked by a plurality of PUCCH resources.

It should be noted that the UCI transmission method provided in the embodiment of the present invention may be applied to a new air interface unlicensed (NR unlicensed) scenario, and certainly, the method is not limited to this, and may also be applied to other scenarios requiring the terminal to transmit the UCI.

Referring to fig. 3, fig. 3 is a flowchart of a UCI transmission method according to an embodiment of the present invention, applied to a network device, as shown in fig. 3, including the following steps:

step 301, sending DCI, where the DCI includes a PUCCH resource indication, and the PUCCH resource indication is used to indicate a PUCCH resource group, where the PUCCH resource group includes multiple PUCCH resources, or the PUCCH resource group is one PUCCH resource group selected from at least one first PUCCH resource group and at least one second PUCCH resource group according to the PUCCH resource indication, where the first PUCCH resource group includes multiple PUCCH resources, and the second PUCCH resource group includes one PUCCH resource;

step 302, receiving UCI on PUCCH resources included in the PUCCH resource group.

Optionally, the PUCCH resource indication is an acknowledgement/negative acknowledgement resource indication ARI.

Optionally, the PUCCH resource indication is used to implicitly indicate the PUCCH resource group, where the PUCCH resource group includes:

the PUCCH resource indication corresponds to a first PUCCH resource;
