摘要： Provided are a method and an apparatus for transmitting a message through a terminal in a wireless communication system. The terminal receives positioning reference signals (PRS) from a reference cell and at least one of the neighbor cells, receives an auxiliary data provision message including a reference cell PRS muting sequence for indicating a muting pattern of the PRS transmitted through the reference cell and a neighbor cell PRS muting sequence for indicating the muting pattern of the PRS transmitted through at least one of the neighbor cells from an enhanced serving mobile location center (E-SMLC), and transmits a reference signal time difference (RSTD) measured on the basis of the PRS received from the reference cell and the at least one of the neighbor cells to the E-SMLC.

摘要： Provided is a relay-synchronization signal (R-SS) transmitting apparatus and method in an orthogonal frequency division multiplexing (OFDM)-based Long Term Evolution Advanced (LTE-A) system having a multi-hop relay. The R-SS transmitting apparatus generates a R-SS having the same peak-to-average power ratio (PAPR) characteristic as a synchronization signal (SS) and having a lower correlation characteristic than the SS, using the SS for synchronization with a terminal, for synchronization between a relay and a base station, for a synchronization between a relay and a subordinate relay, and for monitoring, by a relay, an adjacent base station or an adjacent relay

摘要： Provided is a handover method of a wireless communication system using a hierarchical cellular scheme. In the method, signal quality of a serving node is measured, so that whether to start scanning for a handover is determined. When the scanning for the handover starts, signal qualities of a serving cell including the serving node and one or more neighbor cells are measured through a first preamble including a first identifier for distinguishing a cell. An intra-cell handover or an inter-cell handover is selected using the signal qualities of the serving cell and the neighbor cells. Therefore, a terminal can easily distinguish between the inter-cell handover and the intra-cell handover, and an overhead during a handover can be reduced because an intra-cell handover procedure is simplified.
