Abstract:
Disclosed are a method and an apparatus for transmitting and receiving a signal including cell information in a communication system. An operation method of a terminal comprises the steps of: receiving a first SS/PBCH block from a base station; receiving a second SS/PBCH block from the base station after receiving the first SS/PBCH block; and confirming information included in the first SS/PBCH block and the second SS/PBCH block by performing a combining operation on the first SS/PBCH block and the second SS/PBCH block when a transmission beam of the first SS/PBCH block is the same as a transmission beam of the second SS/PBCH block. Therefore, the performance of a communication system can be improved.
Abstract:
A method for transmitting and receiving slot setting information in a communication system is disclosed. An operating method of a UE comprises the steps of: receiving, from a base station, a first upper layer message including SFI for indicating a format of a slot; receiving, from the base station, DCI or a second upper layer message for indicating a use of a flexible symbol belonging to the slot set by the SFI; and determining the flexible symbol belonging to the slot as a DL symbol or a UL symbol on the basis of the second upper layer message or the DCI. Therefore, a performance of a communication system can be improved.
Abstract:
Provided is an LDPC (Low Density Parity Check) code for terrestrial cloud broadcast. A method of encoding input information based on an LDPC (Low Density Parity Check) includes receiving information and encoding the input information with an LDPC codeword using a parity check matrix, wherein the parity check matrix may have a structure obtained by combining a first parity check matrix for an LDPC code having a higher code rate than a reference value with a second parity check matrix for an LDPC code having a lower code rate than the reference value.
