Method and apparatus for transmitting data in wireless communication system
A method for transmitting data to a base station (BS) at a user equipment (UE) is discussed. The method includes receiving information regarding a contention-based Physical Uplink Shared Channel (PUSCH) zone including a plurality of contention-based PUSCH resource blocks, allocating at least one contention-based PUSCH resource block for transmission of the data based on the contention-based PUSCH zone information, and transmitting the data to the BS, wherein, when the UE determines to transmit the data using the contention-based PUSCH zone, the information regarding the contention-based PUSCH zone is received through a unicast message.
1. A method for transmitting data to a base station (BS) at a user equipment (UE), the method comprising:
configuring a Physical Uplink Shared Channel (PUSCH) configuration related to a physical random access channel (PRACH),
wherein the PUSCH configuration includes parameters for a modulation and coding scheme (MCS) of the PUSCH, a number of physical resource blocks (PRBs) per PUSCH zone, a time interval for allocating PUSCH zones, and a number of contiguous PUSCH zones in time domain; and
transmitting a random access preamble on the PRACH and uplink (UL) data on the PUSCH.
2. The method according to claim 1 , wherein the PUSCH configuration further includes an initial transmission power reference for the PUSCH.
3. The method according to claim 1 ,
wherein the PUSCH zone for transmission of the UL data is allocated to a subframe in which the random access preamble is transmitted.
4. The method according to claim 1 ,
wherein the PUSCH zone for transmission of the UL data is allocated to a subframe contiguous to a subframe in which the random access preamble is transmitted.
5. The method according to claim 1 , wherein the UL data includes a Radio Resource Control (RRC) message.
6. The method according to claim 1 , wherein the UL data is transmitted to the BS without reception of an uplink (UL) grant needed for transmission of the UL data.
7. The method according to claim 1 , wherein the PRACH is allocated in every subframe.
8. A user equipment (UE) operating in a wireless communication system, the UE comprising:
a Radio Frequency (RF) module; and
a processor operably coupled with the RF module and configured to:
configure a Physical Uplink Shared Channel (PUSCH) configuration related to a physical random access channel (PRACH),
wherein the PUSCH configuration includes parameters for a modulation and coding scheme (MCS) of the PUSCH, a number of physical resource blocks (PRBs) per PUSCH zone, a time interval for allocating PUSCH zones, and a number of contiguous PUSCH zones in time domain; and
control the RF module to transmit a random access preamble on the PRACH and uplink (UL) data on the PUSCH.
9. The UE according to claim 8 , wherein the PUSCH configuration further includes an initial transmission power reference for the PUSCH.
10. The UE according to claim 8 , wherein the PUSCH zone for transmission of the UL data is allocated to a subframe in which the random access preamble is transmitted.
11. The UE according to claim 8 , wherein the PUSCH zone for transmission of the UL data is allocated to a subframe contiguous to a subframe in which the random access preamble is transmitted.
12. The UE according to claim 8 , wherein the UL data includes a Radio Resource Control (RRC) message.
13. The UE according to claim 8 , wherein the UL data is transmitted to a base station (BS) without reception of an uplink (UL) grant needed for transmission of the UL data.
14. The UE according to claim 8 , wherein the PRACH is allocated in every subframe.
