METHOD FOR ENHANCING COVERAGE IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and an apparatus by which a terminal transmits an uplink channel in a wireless communication system, the method comprising the steps of: performing a process for repeatedly transmitting a first uplink channel; performing a process for repeatedly transmitting a second uplink channel, the time for transmitting the second uplink channel being later than the time for transmitting the first uplink channel; and checking whether the transmission of the second uplink channel has been allocated to start before the section of the repeated transmission of the first uplink channel ends, wherein, if the transmission of the second uplink channel has been allocated to start before the section of the repeated transmission of the first uplink channel ends and if predetermined conditions are met, the transmission of the first uplink channel is abandoned in the entire section of the repeated transmission or in the section where the transmission of the first uplink channel and the transmission of the second uplink channel overlap.
1 . A method of transmitting an uplink channel by a user equipment (UE) in a wireless communication, comprising:
performing a process for repetitively transmitting a first uplink channel;
performing a process for repetitively transmitting a second uplink channel, a time to transmit the second uplink channel being later than a time to transmit the first uplink channel; and
checking whether transmission of the second uplink channel has been allocated to start before termination of a duration of repetitive transmission of the first uplink channel,
wherein, when transmission of the second uplink channel has been allocated to start before termination of the duration of repetitive transmission of the first uplink channel and when predetermined conditions are met, transmission of the first uplink channel is abandoned at least for a duration for which transmission of the first uplink channel and transmission of the second uplink channel overlap.
2 . The method according to claim 1 , wherein the predetermined conditions correspond to case in which the first uplink channel includes a periodic channel and the second uplink channel includes an aperiodic channel.
3 . The method according to claim 1 , wherein the predetermined conditions correspond to a case in which the first uplink channel includes a PUSCH (Physical Uplink Shared Channel) and the second uplink channel includes HARQ-ACK (Hybrid ARQ Acknowledgement) information.
4 . The method according to claim 1 , wherein the predetermined conditions correspond to a case in which the second uplink channel includes a PRACH.
5 . The method according to claim 1 , wherein the predetermined conditions correspond to a case in which the first uplink channel includes CSI (Channel Status Information) and the second uplink channel includes an SR (Scheduling Request).
6 . A UE used in a wireless communication, comprising:
a radio frequency (RF) unit; and
a processor,
wherein the processor is configured to perform a process for repetitively transmitting a first uplink channel, to perform a process for repetitively transmitting a second uplink channel, a time to transmit the second uplink channel being later than a time to transmit the first uplink channel, and to check whether transmission of the second uplink channel has been allocated to start before termination of a duration of repetitive transmission of the first uplink channel,
wherein, when transmission of the second uplink channel has been allocated to start before termination of the duration of repetitive transmission of the first uplink channel and when predetermined conditions are met, transmission of the first uplink channel is abandoned at least for a duration for which transmission of the first uplink channel and transmission of the second uplink channel overlap.
7 . The UE according to claim 6 , wherein the predetermined conditions correspond to case in which the first uplink channel includes a periodic channel and the second uplink channel includes an aperiodic channel.
8 . The UE according to claim 6 , wherein the predetermined conditions correspond to a case in which the first uplink channel includes a PUSCH and the second uplink channel includes HARQ-ACK information.
9 . The UE according to claim 6 , wherein the predetermined conditions correspond to a case in which the second uplink channel includes a PRACH.
10 . The UE according to claim 6 , wherein the predetermined conditions correspond to a case in which the first uplink channel includes CSI and the second uplink channel includes an SR).
