Method and apparatus for transmitting and receiving downlink signal in next generation wireless network

Abstract:

Provided are a method and apparatus for transmitting and receiving a downlink signal for supporting effective multiplexing between data traffic having mutually different QoS requirements in a next generation/5G wireless access network ("New Radio" (NR)) for which discussion has begun in 3GPP. The method may include receiving configuration information for receiving downlink pre-emption indication data from a base station; monitoring the downlink pre-emption indication data based on the configuration information; and receiving the downlink pre-emption indication data through a multicast or unicast signal, wherein the downlink pre-emption indication data indicates superposed radio resources for providing a first service and for providing a second service.
