Abstract: Disclosed are methods for prompt re-direction of uplink access of a specific user equipment and controlling random access. Specifically, for initial random access to a network, if a user equipment (UE) transmits a preamble (S201), which includes information related to random access, to a network node, the network node sends grant/rejection information of the preamble and re-direction information as a response message to the preamble (S203) to the UE.
Abstract: A method for generating an iterative sequence and a signal transmission method using the same are disclosed. As the cell size or the distance between a user equipment (UE) and a Node-B increases, the CP is repeated at least one time while the iterative sequence is generated, the CP length and the ZCZ length are adjusted, so that the sequence timing point can be easily detected, orthogonality between sequences is maintained, and the sequences can be clearly distinguished from each other.
Abstract: A method in which a user equipment processes data in a wireless mobile communication system is provided. The method includes the steps of receiving a first data block from an upper layer, transferring a second data block including the first data block to a lower layer at a particular protocol layer, discarding the first and second data blocks present in the particular protocol layer if a certain period of time has passed, and transferring information associated with the discard of the second data block to the lower layer.
Abstract: A method for providing precoding weights for data symbols of data control subframes includes generating a downlink frame having control subframes which individually correspond to one of a plurality of downlink data subframes, and inserting weight information into each of the control subframes, such that the weight information is to be applied to data symbols present in the corresponding one of the data subframes.
