Abstract
A method and device for transmitting and receiving a signal in a wireless communication system, according to one embodiment of the present invention, comprises transmitting a physical random access channel (PRACH) and receiving a random access response (RAR) on the basis of the PRACH, wherein the PRAM is transmitted via one random access channel (RACH) occasion (RO) of ROs in a RACH slot, timing gap durations exist between the ROs, and the same timing gap durations can be set even if a PRACH format and/or a subcarrier spacing (SCS) used for the PRACH are changed.
Claims15
A method for enabling a user equipment (UE) to transmit and receive signals in a wireless communication system comprising:
- transmitting a physical random access channel (PRACH);
- and
- receiving a random access response (RAR) based on the PRACH,
- wherein
- the PRACH is transmitted through one RACH occasion (RO) from among a plurality of RACH occasions (ROs) included in a random access channel (RACH) slot,
- a plurality of time gap durations is present between the ROs, and
- the time gap durations are configured to be the same value regardless of changes in a subcarrier spacing (SC S) used in the PRACH and/or regardless of changes in a PRACH format.
A user equipment (UE) configured to transmit and receive signals in a wireless communication system comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory operatively connected to the at least one processor, and configured to store instructions such that the at least one processor performs specific operations by executing the instructions,
- wherein the specific operations include:
- transmitting a physical random access channel (PRACH);
- and
- receiving a random access response (RAR) based on the PRACH,
- wherein
- the PRACH is transmitted through one RACH occasion (RO) from among a plurality of RACH occasions (ROs) included in a random access channel (RACH) slot,
- a plurality of time gap durations is present between the ROs, and
- the time gap durations are configured to be the same value regardless of changes in a subcarrier spacing (SCS) used in the PRACH and/or regardless of changes in a PRACH format.
A device configured to operate for a user equipment (UE) comprising:
- at least one processor;
- and
- at least one memory operatively connected to the at least one processor, and configured to store instructions such that the at least one processor performs specific operations by executing the instructions,
- wherein the specific operations include:
- transmitting a physical random access channel (PRACH);
- and
- receiving a random access response (RAR) based on the PRACH,
- wherein
- the PRACH is transmitted through one RACH occasion (RO) from among a plurality of RACH occasions (ROs) included in a random access channel (RACH) slot,
- a plurality of time gap durations is present between the ROs, and
- the time gap durations are configured to be the same value regardless of changes in a subcarrier spacing (SCS) used in the PRACH and/or regardless of changes in a PRACH format.
