US 12,113,622 B2 · Method for feedback control, UE, and network device

Abstract

Embodiments of this disclosure provide a method for feedback control, UE, and a network device. Specifically, the method for feedback control includes: receiving, by the UE, first downlink control information DCI from a network device, where the first DCI includes a first field, and the first field is used to indicate whether hybrid automatic repeat request acknowledgment HARQ-ACK information for at least one physical downlink shared channel PDSCH group is carried on a first uplink control channel for transmission. The first uplink control channel is indicated by the first DCI, the first field occupies M bits, M is a positive integer less than P, and P is a maximum number of PDSCH groups applicable to the UE. The method is specifically applied to a scenario in which the UE sends feedback information to the network device.
