Method and device for transmitting or receiving data in next generation wireless access network
Provided is a method for designing downlink control channel for satisfying requirement of the different usage scenarios from each other in a next-generation/5G radio access network which has been discussed in the 3rd generation partnership project (3GPP). In particular, a method of a base station may be provided for transmitting/receiving data in a next-generation radio access network. The method may include configuring a time domain scheduling unit made up of at least one OFDM symbol for each user equipment, allocating a downlink data channel transmission resource with the time domain scheduling unit for a first user equipment, and puncturing a part of the downlink data channel transmission resource for the first user equipment and allocating the punctured resource to the downlink data channel transmission resource for a second user equipment.
