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:
There is provided a method for performing a logical channel prioritization. The method may comprise: receiving an uplink (UL) grant; identifying a set of logical channels whose data are to be transmitted using the uplink grant; and performing a logical channel prioritization (LCP) based on the identified set of logical channels.
Abstract:
Provided is a method for enabling a terminal to handle traffic in a wireless communications system. The method includes the steps of: receiving traffic steering information from a first access network, the traffic steering information containing a first traffic steering rule prescribed by the first access network; evaluating the traffic steering based on at least one of the first traffic steering rule and a second traffic steering rule; and performing the traffic steering between the first access network and a second access network based on the result of the evaluation of the traffic steering.
Abstract:
A method and apparatus for applying security information in a wireless communication system is provided. A user equipment (UE) obtains first security information and second security information, applies the first security information to a first set of radio bearers (RBs) which is served by a master eNodeB (MeNB), and applies the second security information to a second set of RBs which is served by a secondary eNodeB (SeNB).
Abstract:
Provided is a method for user equipment reselecting a cell in a wireless communication system. The method comprises: obtaining a public land mobile network (PLMN) list from a serving cell, wherein the PLMN list lists a plurality of PLMNs according to businesses sharing the serving cell; obtaining cell reselection information from the serving cell, wherein the reselection information includes a plurality of cell reselection information sets related to the plurality of PLMNs; and reselecting the cell based on the PLMN list and the cell reselection list.
Abstract:
There is provided a method for reporting buffer status. The method may comprise: establishing a first MAC entity for a first eNodeB and a second MAC entity for a second eNodeB; identifying the first MAC entity on which an uplink data is to be transmitted among the first and second MAC entities, if the uplink data becomes available to be transmitted; and triggering a buffer status report (BSR) for the first MAC entity.
