Abstract: A method performed by a wireless device in a wireless communication system is discussed. The method includes receiving, by the wireless device, broadcast signaling from a network, wherein the broadcast signaling informs that the network supports a device-to-device (D2D) related information; after receiving the broadcast signaling, transmitting, by the wireless device, a message including the D2D related information based on a change of the D2D related information to the network; receiving, by the wireless device, D2D radio resources from the network via a dedicated signaling; and performing, by the wireless device, a D2D operation based on the D2D radio resources.

Abstract: The present invention relates to a communication between MAC layer entity and PHY layer entity for parallel random access procedures of dual connectivity. In this scheme, a first PHY entity of a user equipment informs a failure of a random access preamble transmission to a first MAC entity of the UE. Then, the first MAC entity continues or stops a random access procedure without performing procedures for a random access failure.

Abstract: Provided are a method for supporting multimedia broadcast multicast service (MBMS) service continuity by a terminal in a wireless communication system and an apparatus supporting the same. The method may comprise the steps of: entering an RRC state in which cell reselection is not supported; determining whether an MBMS service of interest can be received at a serving frequency for the terminal; and when it is determined that the MBMS service of interest cannot be received at the serving frequency, transmitting an MBMS interest indication message to a network, wherein the terminal may be a terminal not supporting a handover.

Abstract: A user equipment (UE) receives, from a network, a semi-persistent scheduling (SPS) configuration and a physical uplink control channel (PUCCH) resource configuration. The PUCCH resource configuration may be included in the SPS configuration. When a change of an SPS operation is required, the user equipment transmits an SPS change request to the network and receives, from the network, an SPS resource grant activated according to the SPS change request. The user equipment changes allocation of a PUCCH resource allocated according to the PUCCH resource configuration, on the basis of the received SPS resource grant. For example, a timing at which or a period in which the PUCCH resource is allocated can be changed.
