    摘要: A physical channel processor on a wireless device and method for precoding for spatial multiplexing in an open-loop multiple-input multiple-output (MIMO) mobile communication system is disclosed. The method comprises the operation of receiving an input vector block from a layer mapper. The input vector block includes user equipment-specific reference signals (UE-RSs) or data in a physical downlink shared channel (PDSCH). The operation of generating a large delay cyclic delay diversity (CDD) vector block from the input vector block using a precoder configured for large delay CDD on an antenna port follows. The data can be resource element mapped with UE-RSs or channel-state information reference signals (CSI-RSs) in a physical resource block (PRB).

    摘要: Embodiments of a mobile device transmitter and methods for transmitting signals in different signal dimensions are generally disclosed herein. The mobile device transmitter comprises a mapper to map a block of two or more input modulation symbols to different signal dimensions comprising two or more spatial dimensions, and linear transform circuitry to perform a linear transform on the block of mapped input modulation symbols to generate a block of preceded complex-valued output symbols such that each output symbol carries some information of more than one input modulation symbol. The mobile device also comprises transmitter circuitry to generate time-domain signals from the blocks of precoded complex-valued output symbols for each of the spatial dimensions for transmission using the two or more antennas. The precoded complex-valued output symbols are mapped to different signal dimensions comprising at least different frequency dimensions prior to transmission.
