Abstract
The present document discloses a method for transmitting and receiving data by user equipment in a wireless communication system, the method comprising the steps of: receiving a master information block (MIB) from a base station; transmitting a radio resource control (RRC) connection request to the base station on the basis of the MIB; and receiving, from the base station, a response to the RRC connection request, wherein the MIB includes information about one or more duplex modes supportable by the base station, and the RRC connection request includes information about a duplex mode supportable by the user equipment.
Claims13
A method performed by a user equipment (UE), the method comprising:
- receiving, from a base station (BS), a primary synchronization signal and a secondary synchronization signal;
- acquiring synchronization with the BS and a cell identifier (ID) based on the primary synchronization signal and the secondary synchronization signal;
- receiving, from the BS, a physical broadcast channel (PBCH);
- obtaining a Master Information Block (MIB) based on the PBCH;
- transmitting, to the BS, a Radio Resource Control (RRC) setup request message based on the MIB;
- and
- receiving, from the BS, a response to the RRC setup request message,
- wherein the MIB includes information on one or more duplex modes supported by the BS and the RRC setup request message includes information on a duplex mode supported by the UE,
- wherein the information on the one or more duplex modes supported by the BS includes a bitmap, and
- wherein the bitmap indicates whether a Half Duplex (HD) mode, a Full Duplex (FD), a Frequency Division Duplex (FDD) mode, a Time Division Duplex (TDD) mode, and a Space Division Duplex (SDD) mode are supported by the BS.
