Abstract
The present invention discloses a method for transmitting and receiving signals between a user equipment and a base station in a wireless communication system and device for supporting the same. More specifically, the invention discloses a method by which, when a base station transmits synchronization signal blocks in various beam directions, a user equipment achieves synchronization with the base station by detecting the index of a received synchronization signal block and then transmits and receives signals with the base station.
Claims12
A method of transmitting and receiving signals to and from a base station (BS) by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving from the BS, a synchronization signal/physical broadcast channel (SS/PBCH) block;
- determining an index of the received SS/PBCH block based on either a demodulation reference signal (DMRS) sequence for a PBCH included in the SS/PBCH block or a combination of the DMRS sequence and information included in the PBCH,
- wherein the DMRS sequence is initialized in a unit of the SS/PBCH block, based on an initial value determined based on a cell identifier (cell ID) and the index of the SS/PBCH block;
- and
- performing synchronization with the BS based on the determined index of the SS/PBCH block.
A method of transmitting and receiving signals to and from a user equipment (UE) by a base station (BS) in a wireless communication system, the method comprising:
- transmitting at least one synchronization signal/physical broadcast channel (SS/PBCH) block,
- wherein either a demodulation reference signal (DMRS) sequence for a PBCH included in each SS/PBCH block or a combination of the DMRS sequence and information included in the PBCH indicates an index of each SS/PBCH block,
- wherein the DMRS sequence, included in each SS/PBCH block, is initialized in a unit of the SS/PBCH block, based on an initial value determined based on a cell identifier (cell ID) and the index of the SS/PBCH block;
- and
- transmitting and receiving the signals to and from the UE that performs synchronization with the BS based on the at least one SS/PBCH block.
A user equipment (UE) for transmitting and receiving signals to and from a base station (BS) in a wireless communication system, the UE comprising:
- a transmitter;
- a receiver;
- and
- a processor connected to the transmitter and receiver,
- wherein the processor is configured to:
- receive from the BS, a synchronization signal/physical broadcast channel (SS/PBCH) block;
- determine an index of the received SS/PBCH block based on either a demodulation reference signal (DMRS) sequence for a PBCH included in the SS/PBCH block or a combination of the DMRS sequence and information included in the PBCH,
- wherein the DMRS sequence is initialized in a unit of the SS/PBCH block, based on an initial value determined based on a cell identifier (cell ID) and the index of the SS/PBCH block;
- and
- perform synchronization with the BS based on the determined index of the SS/PBCH block.
A base station (BS) for transmitting and receiving signals to and from a user equipment (UE) in a wireless communication system, the BS comprising:
- a transmitter;
- a receiver;
- and
- a processor connected to the transmitter and receiver,
- wherein the processor is configured to:
- transmit at least one synchronization signal/physical broadcast channel (SS/PBCH) block,
- wherein either a demodulation reference signal (DMRS) sequence for a PBCH included in each SS/PBCH block or a combination of the DMRS sequence and information included in the PBCH indicates an index of each SS/PBCH block,
- wherein the DMRS sequence, included in each SS/PBCH block, is initialized in a unit of the SS/PBCH block, based on an initial value determined based on a cell identifier (cell ID) and the index of the SS/PBCH block;
- and
- transmit and receive the signals to and from the UE that performs synchronization with the BS based on the at least one SS/PBCH block.
