Abstract
A method by which a terminal receives data through a plurality of layers of a base station in a wireless communication system is disclosed. Particularly, the method comprises the steps of: receiving, from the base station, the data, which was divided into a plurality of first code blocks, and a particular downlink control indicator (DCI) for the data; and receiving, from the base station, a plurality of second code blocks according to the particular DCI, wherein all of the plurality of second code blocks are received through the same layer.
Claims13
A method for receiving data in a user equipment (UE) through a plurality of layers of a base station in a wireless communication system, the method comprising:
- receiving, from the base station, the data, which are divided into a plurality of first code blocks, and a specific downlink control indicator (DCI) for the data;
- and
- receiving, from the base station, a plurality of second code blocks based on the specific DCI,
- wherein all of the plurality of second code blocks are received through a same layer,
- wherein the plurality of second code blocks are received based on response signals to each of the plurality of first code blocks transmitted based on the specific DCI,
- wherein the plurality of second code blocks are related to the plurality of first code blocks having Negative Acknowledgement (NACK) as a response signal,
- wherein whether a first DCI including code block based scheduling information or a second DCI including transport block based scheduling information is monitored is configured based on a number of response signals having NACK among the response signals to each of the plurality of first code blocks,
- wherein the first DCI is monitored when the number of the response signals having NACK is equal to or smaller than a threshold value and the second DCI is monitored when the number of the response signals having NACK is greater than the threshold value, and
- wherein a first search space configured for monitoring the first DCI is different from a second search space configured for monitoring the second DCI.
A user equipment (UE) for receiving data through a plurality of layers of a base station in a wireless communication system, the UE comprising:
- a radio frequency (RF) module for transmitting and receiving signals to and from the base station;
- and
- a processor connected with the RF module, receiving the data, which are divided into a plurality of first code blocks, and a specific downlink control indicator (DCI) for the data, and receiving a plurality of second code blocks based on the specific DCI,
- wherein all of the plurality of second code blocks are received through a same layer,
- wherein the plurality of second code blocks are received based on response signals to each of the plurality of first code blocks transmitted based on the specific DCI,
- wherein the plurality of second code blocks are related to the plurality of first code blocks having Negative Acknowledgement (NACK) as a response signal,
- wherein whether a first DCI including code block based scheduling information or a second DCI including transport block based scheduling information is monitored is configured based on a number of response signals having NACK among the response signals to each of the plurality of first code blocks,
- wherein the first DCI is monitored when the number of the response signals having NACK is equal to or smaller than a threshold value and the second DCI is monitored when the number of the response signals having NACK is greater than the threshold value, and
- wherein a first search space configured for monitoring the first DCI is different from a second search space configured for monitoring the second DCI.
