摘要： A beam-forming apparatus and method for improving system performance using a spatial interpolation and at least one Angle of Arrival (AoA) in a system based on regular spatial sampling is provided. The AoA is estimated using a carrier-to-interference ratio. Beam-forming angles are distributed and steered in a predefined scheme such that an identical process is applied in all directions. According to this steering, a linear system model is computed based on regular spatial sampling using regular spatial separation at beam angles. Beam-forming performance is improved by compensating for a difference between adaptive and sector-type arrays. Only the steps of computing a spatial interpolation and determining an angle range for beam-forming using at least one AoA are added. The precision of estimating an AoA and the precision of beam-forming increase without an additional antenna. Because the system is simpler than that of an adaptive beam-forming system, significant gain is obtained.

摘要： An apparatus and method are provided for simply estimating joint channel and Direction-of-Arrival (DOA) to efficiently estimate a channel impulse response associated with a spatially selective transmission channel occurring in a mobile radio channel, and performing efficient beam forming using the simplified joint channel and DOA estimation are provided. A receiver estimates the total interference power using power for each interference signal, estimates a spectral noise density, calculates steering vectors considering predetermined DOAs, and jointly calculates optimal weight vectors for each DOA of each user by applying the interference power and the spectral noise density to the steering vectors. The beam forming reduces implementation complexity of a TDD system such as a TD-SCDMA and increases beam forming efficiency in a mobile environment by efficiently using spatial diversity.

摘要： An RNC determines parameters available for measurement of a synchronization signal and second Node B information from a second Node B, transmits the determined parameters to a first Node B during radio link setup and to a UE during radio bearer setup, and transmits parameter selection information to the first Node B and the UE, if it is recognized that measurement of the synchronization signal and the second Node B information is necessary. The first Node B changes a position of a downlink time period over which a downlink channel is transmitted from the first Node B to the UE and a position of an uplink time period over which an uplink channel is transmitted from the UE to the first Node B, according to parameters selected from the parameters. The UE receives the synchronization signal and the second Node B information in the remaining time periods except the changed downlink time period and the changed uplink time period among the plurality of time periods.

摘要： A method of adjusting the transmission time of data in a CDMA communication system. A UE (User Equipment) measures the time difference between the received time of a downlink DPCH (Dedicated Physical Channel) and the transmitted time of an uplink DPCH and reports it to an RNC (Radio Network Controller). The RNC transmits transmission time adjustment information to a node B and the UE if the time difference is out of a predetermined range. The node B then adjusts the transmission time of the downlink DPCH according to the transmission time adjustment information and transmits the downlink DPCH at the adjusted time. The UE receives the downlink DPCH by adjusting a search time for the downlink DPCH according to the transmission time adjustment information.
