Abstract
Disclosed is a method by which a terminal receives a synchronization signal/physical broadcast channel (SS/PBCH) block in an unlicensed band. Particularly, the method comprises: receiving information related to an actual transmitted SS/PBCH block (ATSS) transmitted by a base station; and receiving the SS/PBCH block on the basis of valid bits from among a plurality of bits included in the information related to the ATSS, wherein the number of valid bits can be based on an interval value between SS/PBCH blocks capable of assuming a quasi co-location (QCL).
Claims15
A method of receiving, by a user equipment (UE), a synchronization signal/physical broadcast channel (SS/PBCH) block in an unlicensed band, the method comprising:
- receiving information on an actual transmitted SS/PBCH block (ATSS) transmitted from a base station;
- and
- receiving the SS/PBCH block based on valid bits among a plurality of bits included in the information on the ATSS,
- wherein the valid bits are configured based on that the number of the valid bits is determined by an interval value between SS/PBCH blocks for which QCL (Quasi Co-Location) can be assumed,
- wherein the reception of the SS/PBCH block is performed based on that SS/PBCH block indexes for the unlicensed band are indicated by the valid bits, and
- wherein the number of the SS/PBCH block indexes is equal to the number of the valid bits.
A device configured to receive a synchronization signal/physical broadcast channel (SS/PBCH) block in an unlicensed band, the device comprising:
- at least one processor;
- and
- at least one memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
- receiving information on an actual transmitted SS/PBCH block (ATSS) transmitted from a base station;
- and
- receiving the SS/PBCH block based on valid bits among a plurality of bits included in the information on the ATSS,
- wherein the valid bits are configured based on that the number of the valid bits is determined by an interval value between SS/PBCH blocks for which QCL (Quasi Co-Location) can be assumed,
- wherein the reception of the SS/PBCH block is performed based on that SS/PBCH block indexes for the unlicensed band are indicated by the valid bits, and
- wherein the number of the SS/PBCH block indexes is equal to the number of the valid bits.
A user equipment (UE) configured to receive a synchronization signal/physical broadcast channel (SS/PBCH) block in an unlicensed band, the UE comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
- receiving information on an actual transmitted SS/PBCH block (ATSS) transmitted from a base station through the at least one transceiver;
- and
- receiving the SS/PBCH block through the at least one transceiver based on valid bits among a plurality of bits included in the information on the ATSS,
- wherein the valid bits are configured based on that the number of the valid bits is determined by an interval value between SS/PBCH blocks for which QCL (Quasi Co-Location) can be assumed,
- wherein the reception of the SS/PBCH block is performed based on that SS/PBCH block indexes for the unlicensed band are indicated by the valid bits, and
- wherein the number of the SS/PBCH block indexes is equal to the number of the valid bits.
