Abstract
Disclosed herein is a method for transmitting a physical random access channel (PRACH) by a user equipment in a wireless communication system. In particular, the method includes receiving information about PRACH resource allocation, and transmitting, based on the information, the PRACH on any one of one or more PRACH occasions allocated in a PRACH slot, wherein a number of the one or more PRACH occasions is based on a preamble format and a starting Orthogonal Frequency Division Multiplexing (OFDM) symbol for the PRACH.
Claims16
A method for a user equipment (UE) in a wireless communication system, the method comprising:
- receiving configuration information related to a physical random access channel (PRACH);
- and
- transmitting, based on the configuration information, the PRACH in a PRACH occasion among at least one PRACH occasion,
- wherein the at least one PRACH occasion is included in a PRACH slot,
- wherein a number of the at least one PRACH occasion is related to (i) a preamble format of the PRACH and (ii) a starting symbol at which the at least one PRACH occasion is started,
- wherein the starting symbol is included in a 2nd half of the PRACH slot, and
- wherein the starting symbol and the preamble format satisfy a preconfigured corresponding relation.
An apparatus in a wireless communication system, the apparatus comprising:
- a memory;
- and
- at least one processor coupled with the memory,
- wherein the at least one processor is configured to:
- receive configuration information related to a physical random access channel (PRACH);
- and
- transmit, based on the configuration information, the PRACH in a PRACH occasion among at least one PRACH occasion,
- wherein the at least one PRACH occasion is included in a PRACH slot,
- wherein a number of the at least one PRACH occasion is related to (i) a preamble format of the PRACH and (ii) a starting symbol at which the at least one PRACH occasion is started,
- wherein the starting symbol is included in a 2nd half of the PRACH slot, and
- wherein the starting symbol and the preamble format satisfy a preconfigured corresponding relation.
A method for a base station (BS) in a wireless communication system, the method comprising:
- transmitting configuration information related to a physical random access channel (PRACH);
- and
- receiving, in response to the configuration information, the PRACH in a PRACH occasion among at least one PRACH occasion,
- wherein the at least one PRACH occasion is included in a PRACH slot,
- wherein a number of the at least one PRACH occasion is related to (i) a preamble format of the PRACH and (ii) a starting symbol at which the at least one PRACH occasion is started,
- wherein the starting symbol is included in a 2nd half of the PRACH slot, and
- wherein the starting symbol and the preamble format satisfy a preconfigured corresponding relation.
An apparatus in a wireless communication system, the apparatus comprising:
- a memory;
- and
- at least one processor coupled with the memory,
- wherein the at least one processor is configured to:
- transmit configuration information related to a physical random access channel (PRACH);
- and
- receive, in response to the configuration information, the PRACH in a PRACH occasion among at least one PRACH occasion,
- wherein the at least one PRACH occasion is included in a PRACH slot,
- wherein a number of the at least one PRACH occasion is related to (i) a preamble format of the PRACH and (ii) a starting symbol at which the at least one PRACH occasion is started,
- wherein the starting symbol is included in a 2nd half of the PRACH slot, and
- wherein the starting symbol and the preamble format satisfy a preconfigured corresponding relation.
