Problems solved by technology

[0006] The above method can be applied to the ACK / NACK information transmission of a single PDSCH, but it is still not suitable for the ACK / NACK information feedback of multiple PDSCHs
[0007] The ACK / NACK information of multiple PDSCHs may need to be fed back in one PUCCH. At each time, due to the possible loss of PDCCH, the terminal (UE) has ambiguity about the indication of the base station through the PDCCH. For example, the base station sent 3 PDCCHs , but the UE only receives 2 of them, so the PUCCH resources corresponding to the UE are inconsistent with the resources actually allocated by the base station, resulting in the ACK / NACK information sent by the UE not being received by the base station, resulting in system confusion

Embodiment 1

[0093] Please refer to figure 2 , an embodiment of the present invention provides a resource indication method for Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) information, which can be applied to network side equipment, such as base stations, such as figure 2 As shown, the method includes:

[0094] Step 21, configure a resource set including multiple PUCCH resources for the terminal, the PUCCH resources are used to carry the bits of the HARQ-ACK information of the PDSCH, and the length of the bits is based on the pre-configuration in the same PUCCH resource. The maximum number of PDSCHs for ACK information transmission is determined, or the maximum number of PDCCHs corresponding to the same PUCCH resource for HARQ-ACK information transmission is determined in advance.

[0095] Here, the network side device may configure the above resource set for the terminal by means of RRC signaling or the like. The RRC signaling may include relevant configuration parameter...

Embodiment 2

[0164] Please refer to Figure 8 , an embodiment of the present invention provides a resource indication method for Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) information, which can be applied to network side equipment, such as base stations, such as Figure 8 As shown, the method includes:

[0165] Step 81, configure a resource set including multiple PUCCH resources for the terminal.

[0166] Here, the PUCCH resources are used to bear the bits of the HARQ-ACK information of the PDSCH. In this embodiment, the length of the bits is variable, so that the network side can configure resources of a corresponding size according to the needs of HARQ-ACK feedback, thereby saving resource overhead for HARQ-ACK information transmission. The resource set may include multiple PUCCH resource subsets, and each subset may include at least one PUCCH resource.

[0167]Step 82: Through the PUCCH resource indication information in the PDCCH, indicate to the terminal the PUCCH r...

Abstract

The embodiment of the invention provides a resource indication method, a resource determination method and device. According to the embodiments of the present invention, a plurality of PDSCHs can be simply and clearly indicated to a terminal to feed back HARQ-ACK information on a single PUCCH resource. Besides, according to the embodiment of the invention, the same group of PDCCHs have the same PUCCH resource indication information, or at least two PUCCH resources are reserved for the terminal, so that the receiving success rate of the network side equipment on the ACK / NACK information can beimproved, and the working stability of the system is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a resource indication method, a resource determination method and equipment. Background technique [0002] In the technical discussion of 5G new air interface (NR, New Radio), a hybrid physical uplink control channel (PUCCH, Physical Uplink Control Channel) indication method is proposed, which is applied to a single PUCCH to feed back a single physical downlink shared channel (PDSCH, Physical Downlink Shared Channel) Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) information, a specific method includes the following steps: [0003] 1) Use RRC signaling to indicate a resource set, the RRC signaling needs to indicate specific configuration parameters, and obtain the corresponding PUCCH resource set according to these configuration parameters; [0004] 2) Use 2-bit PUCCH resource indicator information (PUCCH resource Indicator) to indicate one of the...
