Abstract
The present description provides a method for transmitting uplink (UL) data in a wireless communication system. A method, which is carried out by means of a terminal, comprises the steps of: receiving, from a base station, control information related to transmission of low latency radio (LLR) service data; transmitting, on the basis of the received control information, the low latency radio service data to the base station through an urgent channel, wherein the control information comprises urgent channel information and/or urgent bearer information defined for transmission of the low latency radio service data.
Claims18
A method performed by a base station in a wireless communication system, the method comprising:
- transmitting, to a user equipment (UE), control information related to a transmission of data;
- and
- receiving, from the UE, the data based on the control information,
- wherein the control information is based on an uplink (UL) grant,
- wherein the data is received based on a specific logical channel which is selected based on a logical channel prioritization (LCP), and
- wherein, based on that the transmission of the data is related to a low latency service:
- the specific logical channel is based on a logical channel which is mapped to uplink transmission related to the low latency service, and
- the data based on the specific logical channel is not multiplexed, in a same transport block, with other data based on a logical channel not mapped to the uplink transmission related to the low latency service.
A base station for operating in a wireless communication system, the base station comprising:
- a radio frequency (RF) transceiver;
- a processor;
- and
- a memory operably connectable to the processor and storing instructions that, based on being executed by the processor, perform operations comprising:
- transmitting, to a user equipment (UE), control information related to a transmission of data;
- and
- receiving, from the UE, the data based on the control information,
- wherein the data is received based on a specific logical channel which is selected based on a logical channel prioritization (LCP),
- wherein the control information is based on an uplink (UL) grant, and
- wherein, based on that the transmission of the data is related to a low latency service:
- the specific logical channel is based on a logical channel which is mapped to uplink transmission related to the low latency service, and
- the data based on the specific logical channel is not multiplexed, in a same transport block, with other data based on a logical channel not mapped to the uplink transmission related to the low latency service.
At least one non-transitory computer-readable media storing instructions that, based on being executed by at least one processor, perform operations comprising:
- transmitting, to a user equipment (UE), control information related to a transmission of data;
- and
- receiving, from the UE, the data based on the control information,
- wherein the data is received based on a specific logical channel which is selected based on a logical channel prioritization (LCP),
- wherein the control information is based on an uplink (UL) grant, and
- wherein, based on that the transmission of the data is related to a low latency service:
- the specific logical channel is based on a logical channel which is mapped to uplink transmission related to the low latency service, and
- the data based on the specific logical channel is not multiplexed, in a same transport block, with other data based on a logical channel not mapped to the uplink transmission related to the low latency service.
