Abstract

The invention provides a transmission feedback method and user equipment. The method comprises the steps: transmitting a time-frequency transmission resource which is used for feeding back the feedback information of unicast or multicast transmission to at least one target UE which builds connection with source user equipment UE; acquiring feedback information sent by the target UE on the time-frequency transmission resource; and determining a unicast or multicast transmission state according to the feedback information. According to the transmission feedback method provided by the embodimentof the invention, the target UE can feed back the transmission state information to the source UE for the unicast and multicast communication modes by introducing the feedback resources, so that retransmission determination between the source UE and the target UE is facilitated, and communication between the source UE and the target UE is ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission feedback method and user equipment. Background technique [0002] V2X (vehicle to everything, information exchange between vehicles and the outside world) technology uses wireless communication between vehicles, vehicles and road test infrastructure, and vehicles and passers-by to sense the surrounding conditions of vehicles in real time and share road information and give timely warnings. It has become a research hotspot to solve the problem of road safety. [0003] In the existing LTE (Long Term Evolution, long-term evolution) V2X technology (such as Rel-14LTE V2X technology), the PC5 interface (also called a direct link) for transmitting data between UE (User Equipment, user equipment) and UE ) can already support basic road safety-based service transmission. [0004] With the further development of the Internet of Vehicles technology, some new ...
