Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for triggering a buffer status reporting in the wireless communication system, the method comprising: calculating an amount of first DAT when the first data is arrived in a protocol entity, wherein the amount of first DAT is less than a threshold; calculating an amount of second DAT when the second data is arrived in the protocol entity, wherein the second data is arrived after the first data is arrived in the protocol entity; and triggering a buffer status report if the amount of second DAT is more than the threshold.
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for power headroom reporting in the wireless communication system, the method comprising: obtaining information related to a power headroom (PH) for the second BS; obtaining PH of activated cells of the UE; and transmitting, to a first BS, the information related to the PH for the second BS and the PH of activated cells of the UE.
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for processing a PDCP reordering function in a dual connectivity system, the method comprising: generating a MAC PDU (Medium Access Control Protocol Data Unit) if both of a PHR (Power Headroom Reporting) and a sidelink BSR (Buffer Status Reporting) are generated while the UE communicates with other UEs directly using a sidelink; and transmitting the MAC PDU, wherein the PHR is prioritized over the sidelink BSR when the UE prioritizes between the PHR and the sidelink BSR in the generated MAC PDU.
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for monitoring On Durations in the wireless communication system, the method comprising: receiving DRX information and indicator for selecting On Durations to be used for the UE; calculating one or more first On Durations in a DRX cycle based on the DRX information; and monitoring one or more second On Durations among the one or more first On Durations based on the indicator, wherein each On Duration comprises one or more subframes.
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for monitoring paging occasions in the wireless communication system, the method comprising: receiving paging information and an indicator for selecting paging occasions (POs) to be used for the UE; calculating one or more first POs in a paging frame based on the paging information; and monitoring one or more second POs among the one or more first POs based on the indicator.
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for processing a PDCP reordering function in a dual connectivity system, the method comprising: performing a PDCP (Packet Data Convergence Protocol) reordering function using a reordering timer; receiving an RRC (Radio Resource Control) reconfiguration message indicating a PDCP entity is to be associated with one RLC entity; and disabling the PDCP reordering function immediately by resetting the reordering timer if the PDCP entity is re-established according to the RRC reconfiguration message.
Abstract:
A method for processing a signal at a user equipment in a wireless communication system is disclosed. The method includes steps of constructing a PHR (Power Headroom Report) MAC (Medium Access Control) control element for at least one cell; reconstructing the PHR MAC control element by replacing information on the transmission power of the at least one cell with padding bits, if an indication indicating that a transmission of the at least one cell does not occur is received from a network; and transmitting the PHR MAC control element to the network.
Abstract:
The present disclosure relates to a method for managing LBT (Listen before Talk) failure with a beam group in a wireless communication system. In particular, the method includes the steps of: receiving information related to a first beam group including a first beam and a at least one second beam; and performing a data transmission via the at least one second beam based on a Listen before talk (LBT) failure being detected for the first beam, wherein, based on the LBT failure being detected for both the first beam and the at least one second beam, a LBT failure recovery procedure for the first beam group is performed.
Abstract:
The present disclosure relates to a method of transmitting a One-shot Hybrid Automatic Repeat and request (HARQ) feedback by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: receiving a One-shot HARQ acknowledgement (ACK) request message related to a plurality of HARQ processes from a network; transmitting a One-shot HARQ-ACK related to the plurality of HARQ processes to the network, wherein at least one Round-Trip Time (RTT) timer related to at least one HARQ process, for which a corresponding RTT timer and a corresponding retransmission timer not being running, is started upon transmitting the One-shot HARQ-ACK; starting at least one retransmission timer based on the at least one RTT timer expiring; and monitoring at least one Physical Downlink Control Channel (PDCCH) for the at least one HARQ process during the at least one retransmission timer is running.
Abstract:
A method and apparatus for dynamic configuration of a maximum number of sidelink retransmissions for a data unit in a wireless communication system is provided. A first wireless device in sidelink receives, from a network, information related to a first retransmission number for a first logical channel and a second retransmission number for a second logical channel. The first wireless device determines a retransmission number of a data unit among the first retransmission number and the second retransmission number, and performs sidelink transmission of the data unit to a second wireless device based on the retransmission number of the data unit.
