Description

Communication methods, devices, terminal equipment and wireless access network equipment

Technical field

The embodiments of the present application relate to communication technology, and in particular, to a communication method, device, terminal equipment and wireless access network equipment.

Background technique

In the New Radio (NR) communication system, in order to achieve high reliability, the Physical Uplink Control Channel (PUCCH) repeated transmission technology is proposed, which can support up to 8 repeated transmissions of the PUCCH. Among them, PUCCH repeated transmission technology can be applied in a single transmission and reception point (Transmission and Reception Point, TRP for short) scenario. In a single TRP scenario, a cell is covered by one TRP. When the terminal device located in the cell repeatedly transmits the PUCCH, it uses a PUCCH resource indicated by the network to repeatedly transmit the PUCCH. For example, the terminal terminal device learns which PUCCH resource is triggered based on the downlink control information (DCI), and uses the PUCCH resource to repeatedly transmit the PUCCH.

However, the above-mentioned PUCCH repeated transmission technology cannot be adapted to multiple TRP scenarios. In a multi-TRP scenario, therefore, how to implement PUCCH repeated transmission in a multi-TRP scenario is an issue that needs to be solved urgently.

It is worth noting that there may be two radio access network devices communicating with the terminal device, or any number greater than two. In the embodiment of this application, two radio access network devices are used, that is, the above-mentioned first radio access network device and the third radio access network device.

As an example, the first radio access network device and the second radio access network device may negotiate in advance to determine whether one of the two will send the indication information to the terminal device. In this embodiment, the first radio access network device sends indication information to the terminal device as an example.

Optionally, the first radio access network device can determine whether the terminal device needs to repeatedly send the PUCCH according to the preconfiguration information. If the first radio access network device determines that the terminal device needs to repeatedly send the PUCCH, the first radio access network device can send the above indication information to the terminal device. .

Optionally, the above indication information may be, for example, DCI, and the first radio access network device indicates at least two PUCCH resources through DCI.

It should be understood that the above indication information may also be other messages or information other than DCI, and the embodiment of the present application does not limit the specific name and form of the indication information. In order to describe the solutions of the embodiments of the present application more clearly, the following embodiments take the indication information as DCI as an example for description.

S202. The terminal device repeatedly sends PUCCH on at least two PUCCH resources based on the resource identifiers of the at least two PUCCH resources.

Optionally, the terminal device may repeatedly send PUCCH to at least two radio access network devices on the at least two PUCCH resources.

Optionally, each of the above at least two PUCCH resources is used to repeatedly send PUCCH to a radio access network device. Exemplarily, the first radio access network device indicates two PUCCH resources to the terminal device through DCI, which are the first PUCCH resource and the second PUCCH resource. The first PUCCH resource is used to repeatedly send PUCCH to the first radio access network device, and the second PUCCH resource is used to repeatedly send PUCCH to the second radio access network device. Correspondingly, as shown in the example of Figure 2, the terminal device may repeatedly send the PUCCH to the first radio access network device on the first PUCCH resource, and repeatedly send the PUCCH to the second radio access network device on the second PUCCCH resource.

Optionally, the number of PUCCH resources indicated by the above indication information may be the same as the number of radio access network devices communicating with the terminal device. Alternatively, the number of PUCCH resources indicated by the above indication information may also be smaller than the number of radio access network devices communicating with the terminal device.

In one example, the first radio access network device determines based on the preconfiguration information that the terminal device needs to repeatedly send the PUCCH to each radio access network device in multiple radio access network devices communicating with the terminal device. In this case In this case, the number of PUCCH resources indicated by the first radio access network device may be the same as the number of radio access network devices communicating with the terminal device, so that the terminal device can use the PUCCH resources of multiple radio access network devices. The PUCCH is sent repeatedly to each radio access network device.

In another example, the first radio access network device determines based on the preconfiguration information that the terminal device needs to repeatedly send the PUCCH to some of the multiple radio access network devices communicating with the terminal device. In this case In this case, the number of PUCCH resources indicated by the first radio access network device may be less than the number of radio access network devices communicating with the terminal device, and the terminal device uses these PUCCH resources to repeatedly send PUCCH to some of the above-mentioned radio access network devices. .

Optionally, the above resource identifier of the PUCCH resource can be used to enable the terminal device to determine the specific configuration information of the resource. It should be understood that the resource identifier may uniquely identify a resource, or may not uniquely identify a PUCCH resource. The specific information of the resource identifier will be described in detail in the following embodiments.

In this embodiment, the radio access network device indicates at least two PUCCH resources to the terminal device, and the terminal device accordingly repeatedly sends PUCCH on the at least two PUCCH resources to at least two radio access network devices, so that the In multiple TRP scenarios, the terminal device repeatedly sends PUCCH.

Optionally, the first radio access network device may indicate the PUCCH resource in the indication information using any of the following methods.

In a first optional implementation, in the above step S201, the first radio access network device may carry a resource indication in the indication information, and the terminal device may determine the resources of the at least two PUCCH resources based on the resource indication. identification, and then the terminal device repeatedly sends PUCCH on the PUCCH resource based on the resource identification.

Figure 3 is a schematic flow chart of the communication method provided by the embodiment of the present application. As shown in Figure 3, an optional method of the above step S202 includes:

S301. The terminal device obtains the target PUCCH resource indication according to the above indication information.

Optionally, the first radio access network device may carry PUCCH resource indication information in the above indication information.

For example, the above indication information is DCI. The radio access network device can carry the PUCCH resource indication information in the PUCCH resource indicator field. The terminal device can carry the PUCCH resource indication information according to the PUCCH resource indicator field and/or the control channel element (Control Channel Element) of the terminal device. CCE)index for short, obtain the PUCCH resource indication.

Optionally, before sending the above indication information, the first radio access network device may first determine at least two PUCCH resources for the terminal device to repeatedly transmit the PUCCH, and each PUCCH resource has a unique PUCCH resource index. The first radio access network device then determines the target PUCCH resource indication corresponding to the at least two PUCCH resources according to the corresponding relationship between the PUCCH resource indication and the PUCCH resource index, and generates the above indication information according to the target PUCCH resource indication. The target PUCCH resource indication is indicated through the above indication information.

S302: The terminal device determines the indexes of the at least two PUCCH resources corresponding to the target PUCCH resource indication according to the corresponding relationship between the PUCCH resource indication and the PUCCH resource index.

Optionally, the corresponding relationship between the PUCCH resource indication and the PUCCH resource index may be a one-to-many relationship. For example, one PUCCH resource indication may correspond to the indices of two or more PUCCH resources.

Optionally, the corresponding relationship between the PUCCH resource indication and the PUCCH resource index can be configured in advance by the radio access network device and sent to the terminal device. Correspondingly, the terminal equipment may receive the corresponding relationship between the PUCCH resource indication and the PUCCH resource index in advance.

Optionally, the corresponding relationship between the PUCCH resource indication and the PUCCH resource index can be configured at the Media Access Control (MAC) layer of the radio access network device.

For example, the corresponding relationship between the PUCCH resource indication and the PUCCH resource index may be a mapping table.

The PUCCH resource index may refer to the unique identifier of the PUCCH resource, and a PUCCH resource may be uniquely determined through the PUCCH index.

S303. The terminal device repeatedly sends PUCCH on the at least two PUCCH resources based on the resource identifier corresponding to the index of the at least two PUCCH resources.

Optionally, the radio access network device can pre-configure the resource identifier corresponding to each PUCCH resource.

For example, configuration may be performed on the MAC layer of the radio access network device in advance.

The radio access network device may send the corresponding relationship between each PUCCH resource and the resource identifier to the terminal device. Specifically, it may be the corresponding relationship between the index of the PUCCH resource and the resource identifier. After learning the index of the PUCCH resource, the terminal device can correspondingly learn the resource identifier of the PUCCH resource.

For example, the resource identifier of the PUCCH resource includes airspace information and the number of symbols, and the terminal device can repeatedly send the PUCCH on the PUCCH resource according to the airspace information and the number of symbols.

Figure 4 is an example diagram of the corresponding relationship between PUCCH resource indication, PUCCH resource index and resource identifier of PUCCH resource in the embodiment of the present application. The radio access network device can indicate a resource indication through the foregoing indication information, and the resource indication can correspond to multiple The index of a PUCCH resource, such as the index 1 of the PUCCH resource and the index 2 of the PUCCH resource shown in Figure 4. Index 1 and index 2 respectively uniquely identify a PUCCH resource. Index 1 and index 2 respectively correspond to the resource identifier of a PUCCH resource. , the resource identifier 1 of the PUCCH resource and the resource identifier 2 of the PUCCH resource as shown in Figure 4. The resource identifier 1 of the PUCCH resource may include one or more configuration information, and the resource identifier 2 of the PUCCH resource may also include one or more configuration information.

In a second optional implementation manner, in the above step S201, the first radio access network device may directly carry the indexes of the at least two PUCCH resources in the above indication information.

For example, assuming that the first radio access network device needs to indicate two PUCCH resources to the terminal device, the first radio access network device may carry the first parameter and the second parameter in the DCI, where the first parameter and the second parameter The parameters respectively represent the index of a PUCCH resource.

In addition, as described in step S303 above, the radio access network device may pre-configure the resource identifier corresponding to each PUCCH resource.

After receiving the above indication information, the terminal device can learn the indexes of at least two PUCCH resources by parsing the indication information. Furthermore, the terminal device can learn the resource identifier of the PUCCH resource according to the corresponding relationship between the index of the PUCCH resource and the resource identifier. Furthermore, the terminal device repeatedly sends PUCCH on the PUCCH resource based on the resource identifier.

For example, if the resource identifier of the PUCCH resource is airspace information, the terminal device can repeatedly send the PUCCH on the PUCCH resource according to the airspace information.

Optionally, the resource identifier of the PUCCH resource described in the above two optional implementations may include one type of configuration information or may include multiple types of configuration information. The resource identification of the PUCCH resource may be represented by the configuration information included therein. The configuration information may be air domain information or Transmission Configuration Indicator (TCI for short) status Quasi-Co-Location Type D (QCL-TypeD for short) information, or it may also be the number of symbols of the resource, etc. .

In an example, the resource identifier of the PUCCH resource may include airspace information and the number of symbols of the resource.

Optionally, the resource identifiers of the at least two PUCCH resources may be different from each other, or the resource identifiers of the at least two PUCCH resources may be partially the same, or the resource identifiers of the at least two PUCCH resources may be the same.

The above-mentioned resource identifiers are different in two pairs, which may mean that certain configuration information included in the resource identifiers is different in each pair. For example, assuming that the resource identifier includes airspace information and the number of symbols of the resource, then the resource identifiers are different in pairs, which may mean that the airspace information of each PUCCH resource is different in pairs, and the number of symbols in each PUCCH resource may be different in pairs, or partially. The same, or both can be the same.

In a specific example, it is assumed that the resource identifier includes airspace information and the number of symbols of the resource. It is assumed that the first radio access network device indicates three PUCCH resources. The resource identifiers of the three PUCCH resources are different in pairs. It can refer to the three PUCCH resources. The airspace information of the PUCCH resources is different from pair to pair, and the number of symbols of the three PUCCH resources can be different from pair to pair, partially the same, or all the same.

The above-mentioned resource identifiers are partially identical, which may mean that certain configuration information included in the resource identifiers is partially identical. For example, assuming that the resource identification includes airspace information and the number of symbols of the resource, the resource identification part is the same, which may mean that the airspace information part of each PUCCH resource is the same, and the number of symbols of the three PUCCH resources can be different in two or partially the same. , can also be the same.

In a specific example, it is assumed that the resource identifier includes airspace information and the number of symbols of the resource, and the first radio access network device indicates three PUCCH resources. The resource identifiers of the three PUCCH resources are partially the same, and may refer to the three PUCCH resources. The airspace information of the resources is partly the same. For example, the airspace information of PUCCH resource 1 and PUCCH resource 2 is the same, but the airspace information of PUCCH resource 3 is different from the airspace information of the first two resources. The number of symbols of the three PUCCH resources may be different from each other, may be partially the same, or may all be the same.

Wherein, the above resource identifiers are all the same, which may mean that certain configuration information included in the resource identifiers are all the same. For example, assuming that the resource identifier includes airspace information and the number of symbols of the resource, the resource identifiers are all the same, which can mean that the airspace information of each PUCCH resource is the same, and the number of symbols of the three PUCCH resources can be different in two or partially the same. , can also be the same.

In a specific example, assuming that the resource identifier includes airspace information and the number of symbols of the resource, and assuming that the first radio access network device indicates three PUCCH resources, and the resource identifiers of the three PUCCH resources are all the same, it may refer to the three PUCCH resources. The airspace information of the resources is the same. The number of symbols of the three PUCCH resources may be different from each other, may be partially the same, or may all be the same.

As mentioned above, in the above two optional implementation manners, the index of a PUCCH resource may correspond to a resource identifier. This correspondence relationship can be configured in advance by the wireless access network device and sent to the terminal device. In some scenarios, the radio access network device may not be pre-configured with the corresponding relationship between the index of the PUCCH resource and the resource identifier, or the terminal device may not obtain the corresponding relationship between the index of the PUCCH resource and the resource identifier. In the embodiment of the present application, these scenarios are called scenarios in which the resource identifier of the PUCCH resource is not configured. In these scenarios, the terminal device may use the preset resource identifiers as the resource identifiers of the above-mentioned at least two PUCCH resources.

Take the resource identifier of the PUCCH resource including airspace information or TCI status QCL-TypeD information as an example. If the resource identifier of the PUCCH resource is not configured with airspace information or TCI status QCL-TypeD information, the preset airspace information or TCI status QCL-TypeD information can be It is the active TCI state corresponding to the smallest TCI number or code point among the TCI numbers or code points including two active TCI states.
