Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling of unknown LCID values in a Multicast Channel in a wireless communication system, the method comprising: receiving a MAC PDU including at least one LCID on MCH; discarding a header field containing a first LCID and a corresponding MAC SDU indicated by the header field in the received MAC PDU if the UE does not join an MBMS service transmitted on a MTCH identified by the first LCID currently; and processing remaining parts of the MAC PDU after the header field and the corresponding MAC SDU are discarded from the 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 initiating a random access procedure in a carrier aggregation system, the method comprising: receiving, from a network, a Radio Resource Control (RRC) signal which configures a Physical Uplink Control Channel (PUCCH) resource for a Secondary Cell (SCell) in a Timing Advance Group (TAG); and initiating random access procedure on the SCell with the PUCCH resource to be configured by the RRC signal if there is no cell with PUCCH resource other than the SCell in the TAG.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for allocating uplink resources in the wireless communication system, the method comprising: transmitting, by a first eNB to a second eNB, uplink (UL) resource allocation information for a user equipment (UE) connected with both the first eNB and the second eNB; receiving, by a first eNB from the UE, buffer size information; allocating one or more UL resources to the UE, by considering both of the buffer size information and the UL resource allocation information, wherein the UL resource allocation information indicates a ratio of the buffer size to be considered in each eNB.

Abstract: A method is provided for a user equipment (UE) operating in a wireless communication system. The UE is configured with a first medium access control (MAC) entity and a second MAC entity. The UE triggers a power headroom reporting (PHR) in the first MAC entity if a condition is satisfied. A PHR MAC control element (CE) is generated for the triggered PHR. The UE transmits the PHR MAC CE to a first base station. The condition includes: there is an uplink (UL) transmission on any cell of the second MAC entity, and a required power backoff for the any cell of the second MAC entity has changed more than a threshold.
