摘要： 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.

摘要： Provided are apparatus and method for processing MBS data. The method for receiving multicast/broadcast service (MBS) by a user equipment (UE) may include, when handover is determined, receiving, through a source base station, radio bearer configuration information for receiving MBS session data through a target base station, configuring a radio bearer for receiving the MBS session data through the target base station based on the radio bearer configuration information, and receiving the MBS session data through the radio bearer. The radio bearer configuration information is information generated by the target base station and transmitted to the source base station.

摘要： Provided is a method and an apparatus for for changing or controlling a state of a secondary cell in carrier aggregation. The method includes receiving secondary cell (SCell) state indication information indicating a state for a SCell from a base station through an RRC message or an MAC control element, causing a state of the SCell to transition into a dormant state when the SCell state indication information indicates the dormant state, and transmitting channel state information reporting for the SCell in the dormant state according to an dormant state CQI report period parameter set separately from an activation state CQI report period parameter.
