The present invention provides a search space configuration that is suitable for a communication system in which a plurality of fundamental frequency blocks are grouped together into a wide band. A base station apparatus () has a selection section () that selects a system band in fundamental frequency block units, a downlink control information generation section () that generates downlink control information for demodulating the data channels that are sent separately in the selected fundamental frequency blocks, and arranges, in the downlink control channel of a specific fundamental frequency block among a plurality of fundamental frequency blocks, a search space in which downlink control information for the plurality of fundamental frequency blocks is contained, and a transmission section () that transmits the downlink control channel in which the search space with the downlink control information is arranged.

Base station apparatus and user terminal

A data processing method and a base station for downlink transmit diversity are disclosed. One embodiment of the method comprises: obtaining data symbol groups formed by arranging a first type data symbol and a second type data symbol in an interval, wherein the first type data symbol is more important; determining a first antenna port pairing mode corresponding to a current slot; performing, for OFDM symbols including the reference signal in the current slot, an antenna port and subcarrier mapping on symbols in a transmit diversity matrix corresponding to the data symbol groups according to the first antenna port pairing mode, wherein a subcarrier in which a symbol related to the first type data symbol is located is nearer to a subcarrier in which a reference signal at the same antenna port is located; and performing an inverse fast fourier transform and a cyclic prefix insertion processing on symbols mapped to subcarriers and then mapping the time domain symbols to a physical antenna for transmission. According to embodiments of the invention, comparatively important symbols may obtain better protection.

Data processing method and base station for downlink transmit diversity

The present invention discloses a method and apparatus of physical resource allocation as well as a method of data receiving and a receiving end in a wireless communication system. The method of physical resource allocation includes: detecting a pilot signal sent by each user within a designated range; obtaining received power of the pilot signal sent by each user; scheduling each user within the designated range to obtain a user group including at least one user according to the received power; and allocating a same physical resource to each user of the user group. According to the method and the apparatus, it is possible to reuse a physical resource and sequentially decode data packets corresponding to users in a user group occupying the same physical resource according to the Capture Effect and interference cancellation technology, thereby improving the spectrum efficiency and throughput of uplink or downlink greatly.
