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 receiving system information in a wireless communication system is provided. A user equipment (UE) receives an indication indicating whether a cell supports a short transmission time interval (TTI) from the cell, and receives at least one of normal TTI system information in a normal TTI or short TTI system information in the short TTI from the cell according to the received indication. That is, an eNodeB (eNB) may schedule separate system information block type 1 (SIB1) and/or SI messages broadcast in short TTI.

Abstract: A method and apparatus for operating at a cell not supporting an extended discontinuous reception (eDRX) in a wireless communication system is provided. A user equipment (UE) verifies whether or not a serving cell supports eDRX. If it is determined that the serving cell does not support eDRX, the UE may trigger a tracking area update (TAU). Further, the UE may applying normal DRX cycle at the serving cell and not performing eDRX for a paging reception.

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.
