Abstract: For congestion control is an important aspect for PC5-based vehicle-to-everything (V2X) communication, a channel occupancy ratio (CR) has been introduced. CR is defined as the total number of sub-channels used by a user equipment (UE) for its transmissions divided by the total number of configured sub-channels over a measurement period of 1000 ms. The present invention provides a method and apparatus for calculating a CR over past multiple N subframes up to a subframe at which data is to be transmitted in sidelink. Accordingly, new sidelink transmission (or retransmission) can be considered for CR measurement.

Abstract: A method and apparatus for transmitting an indication for coordination of 3rd generation partnership project long-term evolution (3GPP LTE) and wireless local area network (WLAN) in a wireless communication system is provided. In a cell-specific scheme, an eNodeB (eNB) transmits a first indication of WLAN offloading support to a mobility management entity (MME), and receives a second indication of applying different charging rules from the eNB. Alternatively, in a user equipment (UE)-specific scheme, the eNB transmits a first indication of WLAN offloading support to the MME, receives a second indication of which bearer can be offloaded or not from the eNB, and applies offloading for a specific UE according to the second indication.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method for acquiring, by a first user equipment (UE) in a coverage of a first cell, synchronization in a wireless communication system, the method comprising: receiving a message for a sidelink resource configuration from a second cell through the second UE in a coverage of the second cell; if a channel quality of the second cell is less than a predetermined threshold, selecting the first cell as a synchronization reference cell; and transmitting a sidelink data to the second UE using the sidelink resource configuration based on the synchronization acquired from a synchronization signal of the first cell.

Abstract: According to the present invention, a user equipment (UE) receives a beam-formed paging message based on a feedback, which is transmitted by the UE to a network. The UE receives, in a first period, a paging indicator via multiple beams from a network node, and selects a beam from the multiple beams. Then, the UE transmits, in a second period, a feedback indicating the selected beam to the network node via the selected beam, and monitors, in a third period, the selected beam to acquire a paging message from the network node.

Abstract: According to the present invention, a user equipment (UE) calculates its paging occasion based on a specific beam to monitor paging. In detail, the UE selects at least one beam among multiple beams, calculates a paging occasion consisting of the at least one beam, and monitors a paging in the paging occasion. When the paging occasion consists of the multiple beams including the at least one beam, the paging may be monitored in a part of the paging occasion where the at least one beam is transmitted. Alternatively, when the paging occasion only consists of the at least one beam, the paging may be monitored in all of the paging occasion where the at least one beam is transmitted.
