Embodiment 1

[0071] figure 2 It shows a schematic flowchart of a feedback control method provided by an embodiment of the present invention, as shown in figure 2 As shown, the feedback control method may include step 201 and step 202:

[0072] Step 201: A network device generates a first DCI.

[0073] Specifically, after the network device generates the first DCI, it may send the first DCI to the UE.

[0074] Step 202: the UE receives the first DCI from the network device.

[0075] Wherein, after the network device sends the first DCI, the UE may receive the first DCI.

[0076] Wherein, the first DCI includes a first field, and the first field is used to indicate whether the HARQ-ACK information for at least one PDSCH group is carried and sent on the first uplink control channel, and the first uplink control channel is indicated by the first DCI. Wherein, the first field occupies M bits, M is a positive integer smaller than P, and P is the maximum number of available PDSCH groups of ...

Embodiment 2

[0142] Figure 4 It shows a schematic flowchart of a feedback control method provided by an embodiment of the present invention, as shown in Figure 4 As shown, the feedback control method may include step 401 and step 402:

[0143] Step 401: When the UE sends feedback information for the PDSCH group configured by the network device for the UE, the UE detects that a preset condition is met.

[0144] Step 402: the terminal device sends the target uplink control channel to the network device.

[0145] Correspondingly, the network device can receive the target uplink control channel from the terminal device.

[0146] Wherein, the target uplink control channel carries at least one first target feedback information, each first target feedback information is HARQ-ACK information for one HARQ process, and the HARQ process targeted by at least one first target feedback information is configured by the network device All HARQ processes.

[0147] Similarly, in this embodiment of the...

Embodiment 3

[0173] A flow of a feedback control method provided by an embodiment of the present invention, the feedback control method may include step 501 and step 502:

[0174] Step 501, the network device generates a first DCI.

[0175] Wherein, the first DCI is DCI for the first UE group, and the first UE group includes UEs.

[0176] Specifically, after the network device generates the first DCI, it may send the first DCI to the UE.

[0177] Step 502, the UE receives the first DCI from the network device.

[0178] Wherein, the first DCI includes a first field, and the first field is used to indicate whether the hybrid automatic repeat request response HARQ-ACK information for at least one PDSCH group is carried and sent on the first uplink control channel, and the first field occupies P Bits, P is the maximum number of available PDSCH groups of the UE.

[0179] Optionally, the first uplink control channel is indicated by the first DCI, or the first uplink control channel is configu...

Abstract

The embodiment of the invention provides a feedback control method, UE and network equipment, relates to the technical field of communication, and aims to reduce the bit overhead of indicating a PDSCHpacket to the UE by the network equipment and solve the problem that the correct rate of receiving feedback information by the network equipment is reduced. Specifically, the feedback control methodcomprises the steps that the UE receives first downlink control information DCI from the network equipment, wherein the first DCI comprises a first field, wherein the first field is used for indicating whether hybrid automatic repeat request acknowledgement (HARQ-ACK) information for at least one physical downlink shared channel (PDSCH) packet is carried on a first uplink control channel to be sent, and the first uplink control channel is indicated by a first DCI, wherein the first field occupies M bits, M is a positive integer smaller than P and P is the maximum number of available PDSCH packets of the UE. The method is specifically applied to a scene in which the UE sends feedback information to the network equipment.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a feedback control method, a UE, and a network device. Background technique [0002] In a wireless communication system, in order to ensure the reliability of a User Equipment (UE) receiving a Physical Downlink Shared CHannel (PDSCH), after the UE performs a receiving operation on the PDSCH, the UE may send feedback information to the network device , so as to feed back to the network device whether the UE successfully receives the PDSCH. Specifically, the UE may send feedback information to the network device by using a dynamic codebook-based Hybrid Automatic Repeat reQuest-ACKnowledgement (HARQ-ACK) feedback mechanism, that is, the UE sends feedback information to the PDSCH packet configured for the UE by the network device HARQ-ACK information. [0003] In the dynamic codebook-based HARQ-ACK feedback mechanism, the UE can send HARQ-ACK...
