Abstract: Provided are a method and device for uplink information feedback and downlink data transmission, used, when the speed of motion of a terminal is high, for solving the problem of CSI information reported by the terminal being insufficient to track changes on the channel, such that data transmission carried out on the basis of the channel state information reported by the terminal causes seriously degraded performance. The method comprises: a base station obtaining a precoding matrix of a terminal, and an l-th precoding matrix set of L precoding matrix sets corresponding to said precoding matrix; each precoding matrix set of said L precoding matrix sets containing at least one precoding matrix; said at least one precoding matrix originating from a preset codebook, wherein l≤L and L is a positive integer; according to the precoding matrix contained in the obtained l-th precoding matrix set, the base station sending downlink data to the terminal. By means of the precoding matrix set, a relatively wide beam is formed to cover the user, thus guaranteeing downlink transmission for the terminal when it is moving at high speed, improving the reliability of downlink transmission.

Abstract: The present application discloses a method and an apparatus for signal processing. In the present application, since a front end device in a base station system performs MIMO detection and related baseband-processing of a time domain signal received from an antenna unit and transmits the signal that is baseband-processed to a back end device of the base station system, the back end device merely performs other baseband processing, apart from the MIMO detection and the related baseband processing. Compared with the prior art, the embodiments of the present application move some of the baseband processing forward to be implemented on a front end device such that only the data of each scheduled user with less redundancy are required to be transmitted in an interface between the front end device and a backend device, reducing the pressure on the rate of data transmission between the front end device and the back end device.

Abstract: Disclosed are a method and apparatus for transmitting an initial access signal, thus solving the existing problem wherein transmitting and detecting of synchronization signals cannot be applied to large-scale network coverage of a future communication system. The method comprises: determining at least one to-be-transmitted identification information of a synchronization block, the synchronization block comprising at least two components for transmitting an initial access signal, and different components occupying different time-frequency resources of the synchronization block; determining an initial access signal transmitted by each component in the synchronization block according to the identification information; and determining a time-frequency resource occupied by each component in the synchronization block and transmitting the initial access signal of the component on the time-frequency resource occupied by each component.

Abstract: Disclosed are a broadcast information transmission method and device. A base station uses preset beamforming weight vectors to perform beamforming on a physical broadcast channel. A plurality of preset beamforming weight vectors are used and sequentially selected by the base station to perform beamforming on the physical broadcast channel. Since a plurality of preset beamforming weight vectors are used, a coverage effect on a sector is therefore improved in comparison with a single beam. In addition, the preset beamforming weight vectors are sequentially selected by the base station to perform beamforming on the physical broadcast channel, and broadcast information transmitted by the physical broadcast channel therefore achieves effective coverage.
