    摘要: A method of transmitting and receiving data in a wireless communication system is disclosed. According to an embodiment of the present invention, a base station (BS) transmits downlink data to a first mobile station supporting a first system via a first zone of a frame and transmitting downlink data to a second mobile station supporting a second system via a second zone located behind the first zone by a frame offset on a time axis, wherein the first zone includes the odd number of OFDM symbols and wherein the frame offset is an offset between a start point of a frame for the first system and a start point of a frame for the second system.

    摘要: Disclosed are methods for establishing random access channel (RACH) transmission to prepare against the frequency offset. One of the methods reduces the length of the RACH preamble even if the frequency offset exists, allows the RACH preamble to include a repeated structure (also called an iterative structure) or to use a specific sequence with less affect on the frequency offset, so that the Node-B can easily detect the RACH preamble. If different conditions are established in a high-speed user equipment (UE) and a low-speed UE, an amount of system overheads can be reduced as compared to another case in which an overall RACH condition has been prescribed for only the high-speed UE irrespective of the low- speed UE. And, the method determines whether the UE can estimate its speed according to the aforementioned RACH setup condition, and prescribes a detailed RACH access method according to the determined result.

    摘要: A method for transmitting and receiving control information in a wireless communication system is disclosed. A method for transmitting control information in procedure of data transmission and reception with FDD (frequency division duplex) scheme by a base station of a wireless communication system supporting a mobile station of a first system and a mobile station of a second system includes transmitting information about a number of orthogonal frequency division multiplexing (OFDM) symbols contained in a downlink zone of a frame of the first system in downlink bandwidth to a mobile station of the first system through a 'Number of OFDMA symbols' field of a downlink MAP (DL-MAP); and transmitting information about a number of OFDM symbols contained in an uplink zone of the frame of the first system in uplink bandwidth to the mobile station of the first system through a 'Number of OFDMA symbols' field of an uplink MAP (UL-MAP), wherein the mobile station operates with half-FDD (H-FDD), and the downlink zone of the frame of the first system does not overlap with the uplink zone of the frame of the first system in time domain.
