Abstract: Various embodiments provide a method for performing beam sweeping by a user equipment (UE) in a wireless communication system supporting a sidelink, and a device therefor. Disclosed are a method for performing beam sweeping and a device therefor, the method comprising the steps of: forming a first group for performing the beam sweeping; receiving group information related to the first group; and performing beam sweeping on the basis of the group information, wherein the group information includes area allocation information for a plurality of areas divided on the basis of the number of a plurality of beams that can be formed by UEs included in the first group, and the beam sweeping is performed only within a first area, which has been pre-configured in response to the UEs, from among the plurality of areas.

Abstract: The present invention discloses a method and an apparatus for a terminal receiving control information, which includes a modified physical hybrid ARQ indicator channel (PHICH) configuration, through a downlink shared channel (DL-SCH), in a heterogeneous network system comprising a macro cell and a femto cell. The method for the terminal receiving the control information in the heterogeneous network system comprising the macro cell and the femto cell, according to one embodiment of the present invention, comprises the steps of: the terminal accessing the macro cell undergoing a handover to the femto cell; and receiving PHICH reconfiguration information from the femto cell through the downlink shared channel (DL-SCH), when the configuration of the physical hybrid ARQ indicator channel (PHICH) used by the terminal which has undergone the handover is modified.

Abstract: Disclosed, according to various embodiments, is a method by which a first terminal included in a first traveling group grouped on the basis of a traveling lane reallocates transmission resources on the basis of traveling group information in a wireless communication system that supports a sidelink. Disclosed are a method and an apparatus therefor, the method comprising the steps of: transmitting a signal in a first resource domain to a second terminal included in the first traveling group; receiving group information from a second traveling group in a lane different from that of the first traveling group; determining whether to reallocate the first resource domain, on the basis of the group information including traveling lane information of the second traveling group and information about a second resource domain to be used for signal transmission/reception with a third traveling group that is another traveling group; and transmitting the group information to the second terminal.
