Abstract: Embodiments of the present invention provide a cell configuration method, a device, and a system. The method includes: configuring reference uplink signal-to-interference ratios, UL SIRs/a reference uplink signal-to-interference ratio, UL SIR, for the UE in the first cell and/or the second cell, so that a first reference UL SIR for the UE in the first cell is different from a second reference UL SIR for the UE in the second cell. When the UE is located in a soft handover area and a serving cell is the first cell, power control performed by the first cell on the UE is enhanced so that uplink transmit power of the UE can meet a requirement of the first cell.

Abstract: A method for transmitting data streams in a multiple input multiple output (MIMO) system is provided, where each data stream is mapped to multiple layers in an MIMO channel space for transmission, and the method includes: performing inter-layer interleaving for N data streams to obtain N interleaved data streams; mapping the N interleaved data streams respectively to N layers in the MIMO channel space, and transmitting the N interleaved data streams that are mapped to the N layers. By using the method of the present invention, a combined CQI can be used in a better way to improve MIMO transmission performance. Further, an impact of inter-layer interference is canceled by using an interference cancellation technology (for example, an SIC technology) based on the inter-layer interleaving.

Abstract: This application relates to the field of wireless communications technologies, and in particular, to a data processing method, apparatus, and system. This application provides a data processing method. A data sending device modulates a to-be-transmitted bit sequence, splits a real part and an imaginary part of a complex-valued symbol that is obtained through the modulation into two symbols to form a symbol sequence, performs phase rotation of symbols in the symbol sequence, and performs sending by using a single carrier frequency division multiple access (SC-FDMA) symbol. This application is intended to reduce a peak-to-average power ratio (PAPR) of a transmit signal of an orthogonal frequency division multiplexing (OFDM) system by splitting a real part and an imaginary part of a to-be-transmitted signal, and improve link quality of an entire transmission system.

Abstract: Disclosed is a reference signal transmission method and a device. The method includes converting, by a sending device, a frequency domain reference signal from frequency domain to time domain, to generate a time domain reference signal. The frequency domain reference signal includes a reference signal sequence mapped to a frequency domain resource. The reference signal sequence is determined based on a Zadoff-Chu (ZC) sequence, and a length value of the ZC sequence is selected from at least two length values. The method includes sending, by the sending device, the time domain reference signal. According to the reference signal transmission method, one ZC sequence is selected from at least two ZC sequences with different lengths to generate the reference signal sequence, so that the generated reference signal sequence is characterized by a low PAPR and an low RCM, and is used to generate a reference signal, to improve data transmission performance.
