Method and apparatus for transmitting data in wireless communication system
A method for transmitting data by a user equipment (UE), includes configuring a Physical Uplink Shared Channel (PUSCH) configuration related to a physical random access channel (PRACH), wherein the PUSCH configuration includes parameters fora time interval for allocating PUSCH zones and a number of contiguous PUSCH zones in time domain, and transmitting the PRACH and a PUSCH based on the PUSCH configuration.
1. A method for transmitting data by a user equipment (UE), the method comprising:
receiving information related to a Physical Uplink Shared Channel (PUSCH) configuration through a system information block,
wherein a PUSCH zone is allocated within a time unit, and
wherein the PUSCH configuration includes parameters for a number of consecutive time units for allocating PUSCH zones and a number of contention PUSCH resource blocks in the time unit; and
transmitting a PUSCH on a contention PUSCH resource block among the contention PUSCH resource blocks based on the PUSCH configuration after transmitting a Physical Random Access Channel (PRACH), wherein transmitting the PUSCH and transmitting the PRACH are included in a first step of a 2-step random access procedure.
2. The method according to claim 1 , wherein the PUSCH configuration includes a parameter for a modulation and coding scheme (MCS) of the PUSCH.
3. The method according to claim 1 , wherein the PUSCH configuration includes a parameter for an initial transmission power reference for the PUSCH.
4. The method according to claim 1 , wherein a contention resolution message is received in a second step of the 2-step random access procedure.
5. The method according to claim 1 , wherein the PUSCH is allocated to a subframe consecutive to a subframe in which the PRACH is transmitted.
6. The method according to claim 1 , wherein the PUSCH includes a Radio Resource Control (RRC) message.
7. The method according to claim 1 , wherein the PUSCH is transmitted without reception of an uplink (UL) grant.
8. The method according to claim 1 , wherein the PRACH is allocated in every subframe.
9. A user equipment (UE) operating in a wireless communication system, the UE comprising:
a transceiver; and
a processor operably coupled with the transceiver and configured to:
receive information related to a Physical Uplink Shared Channel (PUSCH) configuration through a system information block,
wherein a PUSCH zone is allocated within a time unit, and
wherein the PUSCH configuration includes parameters for a number of consecutive time units for allocating PUSCH zones and a number of contention PUSCH resource blocks in the time unit; and
control the transceiver to transmit a PUSCH on a contention PUSCH resource block among the contention PUSCH resource blocks based on the PUSCH configuration after transmitting a Physical Random Access Channel (PRACH), wherein transmitting the PUSCH and transmitting the PRACH are included in a first step of a 2-step random access procedure.
10. The UE according to claim 9 , wherein the PUSCH configuration includes a parameter for a modulation and coding scheme (MCS) of the PUSCH.
11. The UE according to claim 9 , wherein the PUSCH configuration includes a parameter for an initial transmission power reference for the PUSCH.
12. The UE according to claim 9 , wherein a contention resolution message is received in a second step of the 2-step random access procedure.
13. The UE according to claim 9 , wherein the PUSCH zone is allocated to a subframe consecutive to a subframe in which the PRACH is transmitted.
14. The UE according to claim 9 , wherein the PUSCH includes a Radio Resource Control (RRC) message.
15. The UE according to claim 9 , wherein the PUSCH is transmitted without reception of an uplink (UL) grant.
16. The UE according to claim 9 , wherein the PRACH is allocated in every subframe.
