Abstract: The present invention relates to a method of transmitting a buffer status report (BSR) by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: configuring at least two logical channel groups (LCGs), wherein each of the at least two LCGs includes at least one logical channel; if all of the at least two LCGs do not have data available for transmission when the BSR is triggered, constructing a Short BSR for a specific LCG among the at least two LCGs; and transmitting the Short BSR to the network.

Abstract: The present disclosure relates to a method for transmitting signals by a user equipment (UE) in a wireless communication system. In particular, the method includes configuring multiple logical channel groups; receiving an uplink grant with information about at least one of the multiple logical channel groups; and performing a buffer status report (BSR) triggering procedure for the at least one of the multiple logical channel groups based on the uplink grant.

Abstract: The present invention relates to a method of performing a Scheduling Request (SR) by a User Equipment (UE) in a wireless communication system. In particular, the method includes the steps of: configuring a logical channel, wherein a SR transmission of the logical channel is prioritized over any Physical Uplink Shared Channel (PUSCH) transmission; and based on the SR being triggered due to the logical channel, transmitting the SR to a network.

Abstract: The present disclosure relates to a method for transmitting signals by a transmission end in a wireless communication system. In particular, the method includes configuring first and second type logical channel groups; receiving a first uplink grant; and transmitting buffer size information based on the uplink grant, wherein, when the first uplink grant is allowed to be used for transmission of buffer size information of the second logical channel group, the buffer size information includes the buffer size information of the first and second logical channel groups, and wherein, when the first uplink grant is not allowed to be used for transmission of buffer size information of the second logical channel group, the buffer size information includes the buffer size information of the first logical channel group.

Abstract: The present invention relates to a method of transmitting a scheduling request (SR) by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: triggering the SR related with a logical channel (LCH); transmitting a buffer status report (BSR) which includes buffer status related to triggering of the SR; and based on not receiving a feedback informing successful reception of the BSR from a network, transmitting the SR, wherein, based on the feedback informing successful reception of the BSR is received, the SR is canceled.

Abstract: A method for transmitting a measurement report by a wireless node in a wireless communication system is disclosed. The method comprises measuring a channel for obtaining channel congestion information; and transmitting the measurement report including the channel congestion information to the network, wherein the channel congestion information is determined based on a number of times a busy period appears and a number of busy samples, within a reporting interval.

Abstract: A method for performing a random access (RA) procedure by a user equipment (UE) in a wireless communication system is provided. The method comprises: selecting a uplink carrier for the RA procedure between a first uplink carrier for a serving cell and a second uplink carrier for the serving cell; and performing a first random access preamble (RAP) transmission for the RA procedure through the selected uplink carrier. Selecting the uplink carrier comprises: selecting the first uplink carrier when a downlink signal quality of the serving cell is less than a first threshold, and selecting one of the first and second uplink carriers randomly when the downlink signal quality of the serving cell is equal to or above the first threshold.

Abstract: The present invention relates to a method for performing a random access procedure by a user equipment in a wireless communication system. In particular, the method includes transmitting a first number of random access preambles; detecting a second number of random access responses corresponding to the first number of random access preambles; and transmitting an payload using one uplink grant for which a listen before talk (LBT) procedure is firstly successful among a second number of uplink grants included in the second number of random access responses.

Abstract: A method for transmitting data through a logical channel by a user equipment (UE) in a wireless communication system is disclosed. The method comprises determining whether data for the logical channel exists or not; increasing a token value based on a prioritized Bit Rate (PBR) and a time elapsed since the data becomes available for the logical channel, when the data for the logical channel exists; and transmitting the data or a part of the data through the logical channel, when the token value is greater than 0, wherein when there is no data for the logical channel, the token value is not increased.
