    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: This disclosure describes systems, methods, and devices related to antenna configuration parameters. A device may determine one or more antennas having one or more phases. The device may determine a first delay associated with a first antenna of the one or more antennas. The device may determine a second delay associated with a second antenna of the one or more antennas. The device may cause to send a frame to a first station device using the first antenna, wherein the frame comprises a first indication of the delay associated with the first antenna and a second indication of the delay associated with the second antenna.
