    摘要: A Downlink Control Information (DCI) processing device and method for a wireless communication system that encodes/decodes downlink control information based on a payload size of DCI format. The method includes determining a payload size of a first DCI format; and determining a payload size of a second DCI format by appending padding bits to the second DCI format until the payload size of the second DCI format is not an ambiguous size and is not equal to the payload size of the first DCI format.

    摘要: Coordinated multipoint communication is a technology for improving cell-edge performance for users in a cell-type mobile communication system. In order to enable a coordinated multipoint transmission/reception operation, a user equipment report of a local environment is required to select both coordinated communication modes and communication partners in evolved Node B (eNB) base stations. According to the present invention, a method is described for feeding back information from User Equipment (UE) to a serving base station to enable a coordinated multi-point transmission/reception operation. The information reported through the feedback is classified into two categories corresponding to received signal intensity information and received signal timing information. The UE may select one or both types of information from between the categories to provide feedback. In embodiments of the present invention, various overhead-reducing reporting formats are described.

    摘要: An initial access method of a user equipment (UE) and an apparatus performing the same are provided. The initial access method of a user equipment attempting access a macro cell base station in a network with which the macro cell base station and at least one Femto cell base station share, includes: receiving a cell ID from the macro cell base station or the Femto cell base station; transmitting an interference control request message to the Femto call base station when the received cell ID is a Femto cell ID; and receiving a macro cell ID provided from the macro cell base station when an interference control response message is received from the Femto cell base station to attempt an initial access. When a macro UE near to a Femto cell base station attempts to access a macro cell, it searches an ID of the macro cell through interference control from the Femto call base station to achieve initial access.
