Method and device for performing initial connection in wireless communication system
In a wireless communication system, user equipment (UE) receives information about an uplink (UL) bandwidth part (BWP) from a network through remaining minimum system information (RMSI), and transmits an MSG 3 of a random access procedure to the network through the UL BWP. The UL BWP can be configured separately from a downlink (DL) BWP.
1. A method performed by a wireless device in a wireless communication system, comprising:
receiving, from a network, information for a numerology;
receiving, from the network, information for an offset between a frequency location of an uplink (UL) bandwidth part (BWP) and a subcarrier 0 of a specific resource block having an index 0 ;
identifying the frequency location of the UL BWP based on the numerology and the offset; and
transmitting, to the network, a message 3 (MSG 3 ) of a random access procedure through the UL BWP on the frequency location,
wherein the frequency location of the UL BWP for the transmitting of the MSG 3 is different from a frequency location of a UL BWP for a transmission of a random access preamble.
2. The method of claim 1 , wherein the UL BWP for the transmitting of the MSG 3 is configured separately from a downlink (DL) BWP.
3. A user equipment (UE) in a wireless communication system, comprising:
a memory;
a transceiver; and
a processor connected to the memory and the transceiver, and configured to:
control the transceiver to receive, from a network, information for a numerology;
control the transceiver to receive, from the network, information for an offset between a frequency location of an uplink (UL) bandwidth part (BWP) and a subcarrier 0 of a specific resource block having an index 0 ;
identify the frequency location of the UL BWP based on the numerology and the offset; and
control the transceiver to transmit, to the network, a message 3 (MSG 3 ) of a random access procedure through the UL BWP on the frequency location,
wherein the frequency location of the UL BWP for the transmitting of the MSG 3 is different from a frequency location of a UL BWP for a transmission of a random access preamble.
4. A method for operating a base station in a wireless communication system, comprising:
transmitting, to a wireless device, information for a numerology;
transmitting, to the wireless device, information for an offset between a frequency location of an uplink (UL) bandwidth part (BWP) and a subcarrier 0 of a specific resource block having an index 0 ; and
receiving, from the wireless device, a message 3 (MSG 3 ) of a random access procedure through the UL BWP on the frequency location,
wherein the frequency location of the UL BWP for the transmitting of the MSG 3 is different from a frequency location of a UL BWP for a transmission of a random access preamble.
5. The method of claim 4 , wherein the UL BWP for the transmitting of the MSG 3 is configured separately from a downlink (DL) BWP.
6. The method of claim 1 , wherein the wireless device is in communication with at least one of a mobile device, a network, or autonomous vehicles other than the wireless device.
