Abstract

The present disclosure discloses a method and device for feedback of grant-free transmission based on a resource unit, the feedback method comprising: a network-side device receiving from at least one user terminal uplink data sent on a resource unit for grant-free transmission, and performing data processing on the uplink data; the network-side device sending feedback information on a feedback resource for grant-free transmission feedback corresponding to the resource unit for grant-free transmission according to a result of the data processing. The method proposes feedback based on a resource unit, which can effectively reduce feedback signaling overhead, combine fast feedback and retransmission, improve the feedback efficiency and increase the success rate of retransmission combining.
