The embodiment of the application provides a method, network equipment, device, electronic equipment and storage medium for distributing Physical Uplink Control Channel (PUCCH) resources, which are used for solving the technical problems of poor PUCCH resource distribution flexibility, multiple needed interaction times and large processing time delay in the related technology.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

Fig. 1 is a flowchart illustrating a method for allocating PUCCH resources of a physical uplink control channel according to an embodiment of the present application.

As shown in fig. 1, the PUCCH resource allocation method according to the embodiment of the present application includes:

S101, responding to the end of downlink scheduling of the main carrier in the target downlink time slot by all terminal equipment accessed by the main cell, and acquiring a first uplink feedback window of the main carrier in the target downlink time slot by any target terminal equipment meeting a preset condition.

It should be noted that, an execution body of the PUCCH resource allocation method according to the embodiment of the present application is a network device corresponding to the primary cell. Wherein the network device may be a base station.

In the embodiment of the application, the downlink scheduling of the main carrier (Primary Component Carrier, PCC) can be performed in the downlink time slot between the network device corresponding to the main cell and any terminal device accessed by the main cell, and the downlink scheduling of the main carrier in the target downlink time slot can be finished in response to all terminal devices accessed by the main cell, and if any target terminal device meets the preset condition, the first uplink feedback window of the main carrier in the target downlink time slot is acquired.

The target downlink time slot refers to a downlink time slot of current downlink scheduling of network equipment corresponding to the primary cell and terminal equipment accessed by the primary cell.

The uplink feedback of the target terminal equipment to the main carrier is fed back in a first target uplink feedback window.

The preset conditions can be set according to actual conditions.

In one embodiment, the preset conditions include at least one of:

condition 1, the target terminal device is configured with a carrier aggregation (Carrier Aggregation, CA) relationship.

In the embodiment of the application, the target terminal equipment can be configured with CA relationship to enhance the transmission bandwidth. It is understood that configuring with the CA relationship may include configuring a primary carrier that is a carrier used by the primary cell and a secondary carrier (Secondary CCComponent Carrier, SCC) that is a carrier used by the secondary cell.

And 2, the target terminal equipment is the main terminal equipment relative to the main cell.

S102, determining at least one target uplink feedback window in a target downlink time slot based on the first uplink feedback window, wherein the target terminal equipment feeds back the uplink feedback of the auxiliary carrier in the target uplink feedback window.

It can be understood that the frame structures of the secondary carrier and the primary carrier, the network systems of the secondary cell and the primary cell, and the feedback timing sequence of the target downlink time slot in the secondary carrier may be different from the feedback timing sequence of the target downlink time slot in the primary carrier, and then the uplink feedback windows of the target terminal device for the secondary carrier and the primary carrier may be different for the same target downlink time slot.

In the embodiment of the application, at least one target uplink feedback window in the target downlink time slot can be determined based on the first uplink feedback window, wherein the target terminal equipment feeds back the uplink feedback of the auxiliary carrier in the target uplink feedback window. Therefore, the method can determine at least one target uplink feedback window based on the first uplink feedback window, and compared with the condition that the PUCCH resource allocation method in the related art is only suitable for the condition that the uplink feedback windows of the main carrier and the auxiliary carrier are the same, the PUCCH resource allocation method is simultaneously suitable for the condition that the uplink feedback windows of the main carrier and the auxiliary carrier are the same and different, the applicability is stronger, and the reliability of the uplink feedback of the auxiliary carrier is ensured.

In one embodiment, determining at least one target uplink feedback window in a target downlink time slot based on a first uplink feedback window includes acquiring a second uplink feedback window of an auxiliary carrier in the target downlink time slot, acquiring a candidate uplink feedback window between the first uplink feedback window and the second uplink feedback window, and determining the first uplink feedback window, the candidate uplink feedback window and the second uplink feedback window as target uplink feedback windows.

For example, as shown in fig. 2, slots 4, 8, 9, 14, 18, and 19 on the primary carrier are uplink feedback windows, and the remaining slots are downlink slots.

If the target downlink time slot is time slot 5, the first uplink feedback window of the main carrier in time slot 5 is time slot 8, the second uplink feedback window of the auxiliary carrier in time slot 5 is time slot 9, and the candidate uplink feedback window between time slot 8 and time slot 9 does not exist, the time slots 8 and 9 can be determined as target uplink feedback windows.

Or if the target downlink time slot is time slot 5, the first uplink feedback window of the main carrier in time slot 5 is time slot 8, the second uplink feedback window of the auxiliary carrier in time slot 5 is time slot 14, and the candidate uplink feedback window between time slot 8 and time slot 14 is time slot 9, then time slots 8, 9 and 14 can be determined as target uplink feedback windows.

In one embodiment, for any carrier of the primary carrier and the secondary carrier, an uplink feedback window of any carrier in the target downlink time slot is obtained according to at least one of a frame structure of any carrier, a network system of a cell corresponding to any carrier, and a feedback timing sequence of the target downlink time slot in any carrier. Therefore, the method can comprehensively consider the frame structure of the carrier, the network system of the cell corresponding to the carrier and the feedback time sequence of the target downlink time slot in the carrier to determine the uplink feedback window of the carrier in the target downlink time slot.

S103, corresponding target PUCCH resources are allocated for each target uplink feedback window, wherein the target PUCCH resources are used for transmitting uplink control information UCI for carrying out uplink feedback on the auxiliary carrier.

In the embodiment of the application, a corresponding target PUCCH resource may be allocated to each target uplink feedback window, where the target PUCCH resource is used to transmit uplink control information (Uplink Control Information, UCI) for uplink feedback on the secondary carrier. It can be understood that different target PUCCH resources can be allocated by different target downlink feedback windows, so that the flexibility is high.

In one embodiment, the UCI may include acknowledgement (ACKnowledgement, ACK) information in hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) feedback information.

In summary, according to the method for allocating PUCCH resources in the embodiment of the present application, the network device corresponding to the primary cell may determine at least one target downlink feedback window based on the first uplink feedback window, and is applicable to the case that the uplink feedback windows of the primary carrier and the secondary carrier are the same or different, so that applicability is strong, and allocate a corresponding target PUCCH resource for each target uplink feedback window, and use the target PUCCH resource to transmit UCI for uplink feedback of the secondary carrier.

On the basis of any one of the above embodiments, the PUCCH resources include a first type of PUCCH resource for transmitting UCI having a data amount greater than a preset threshold and a second type of PUCCH resource for transmitting UCI having a data amount less than or equal to the preset threshold.

The preset threshold may be set according to actual situations, for example, may be set to 2 bits (bits).

On the basis of any of the above embodiments, as shown in fig. 3, in step S103, allocating a corresponding target PUCCH resource for each target uplink feedback window includes:

S301, determining a type of a first PUCCH resource used by a target terminal device for transmitting UCI corresponding to a main carrier in a target uplink feedback window according to each target uplink feedback window.

It can be understood that, in the process that the network device corresponding to the primary cell and the terminal device accessed by the primary cell perform downlink scheduling of the primary carrier in the target downlink timeslot, the first PUCCH resource corresponding to the uplink feedback window may be determined. The first PUCCH resource is used for transmitting UCI for uplink feedback to the primary carrier.

In the embodiment of the application, for each target uplink feedback window, the type of the first PUCCH resource used by the target terminal equipment for transmitting the UCI corresponding to the main carrier in the target uplink feedback window can be determined.

S302, responding to the first PUCCH resource type as a first type, and taking the first PUCCH resource as a target PUCCH resource.

In the embodiment of the application, the first PUCCH resource may be used as the target PUCCH resource if the type of the first PUCCH resource is the first type, which indicates that the data amount of UCI transmitted by the target uplink feedback window is greater than the preset threshold, that is, PUCCH resources allocated for the secondary carrier in the target uplink feedback window are consistent with PUCCH resources used by the primary carrier, which is conducive to saving PUCCH resources.

In one embodiment, allocating a corresponding target PUCCH resource for the target uplink feedback window from the candidate PUCCH resources includes determining that a reserved PUCCH resource is allocated in advance for the secondary carrier within the target uplink feedback window, and taking the reserved PUCCH resource as the target PUCCH resource.
