Abstract
The present disclosure relates to a communication technique in which a 5G communication system for supporting more high data transmission rate after a 4G system converges with an IoT technology, and a system thereof. The present disclosure may be applied to intelligent services (e.g., smart hole, smart building, smart city, smart car or connected car, healthcare, digital education, retail business, security and safety-related services) based on a 5G communication technology and an IoT-related technology.
Claims16
A method for performing communication by a terminal in a wireless communication system, the method comprising:
- measuring a strength of at least one signal received from at least one neighboring cell;
- identifying a second cell having a strength of a received signal greater than a predetermined threshold;
- transmitting, to a first cell, a measurement report message including an identification (ID) of the second cell and the received signal strength;
- receiving, from the first cell, a radio resource control (RRC) reconfiguration message including broadband transmission mode information;
- and
- communicating with the first cell and the second cell, after transmitting a RRC reconfiguration complete message through the first cell,
- wherein the broadband transmission mode information includes at least one of downlink carrier bandwidth information of the second cell, physical downlink shared channel (PDSCH) mapping information of the second cell, and scrambling information for the PDSCH of the second cell, and
- wherein the PDSCH mapping information of the second cell indicates from which OFDM symbol the PDSCH of the second cell is mapped or whether a synchronization signal or a physical broadcast channel (PBCH) is transmitted by the second cell.
A method for performing communication by a base station in a wireless communication system, the method comprising:
