    • A method and apparatus are described for obtaining port index information. In one scenario, downlink (DL) control information (DCI) is received that includes new data indicator (NDI). The NDI has a value indicating an antenna port for single-port transmission. In response to receiving the DCI, a single-port transmission associated with the indicated antenna port is received. The NDI may be associated with a disabled codeword and the DCI may include a second NDI. The DCI may be received over a physical downlink control channel (PDCCH). The DCI may include a resource block (RB) assignment information field (IF), a hybrid automatic repeat request (HARQ) process identity (ID) IF, a transmit power control (TPC) IF and, for each of a plurality of transport blocks, a modulation and coding scheme (MCS), an NDI and a redundancy version (RV).
    • 描述了用于获得端口索引信息的方法和装置。 在一种情况下,接收包括新数据指示符(NDI)的下行链路(DL)控制信息(DCI)。 NDI具有指示用于单端口传输的天线端口的值。 响应于接收到DCI,接收与指示的天线端口相关联的单端口传输。 NDI可以与禁用的码字相关联,并且DCI可以包括第二NDI。 可以通过物理下行链路控制信道(PDCCH)接收DCI。 DCI可以包括资源块(RB)分配信息字段(IF),混合自动重传请求(HARQ)处理标识(ID)IF,发射功率控制(TPC)IF和用于多个传输块 调制和编码方案(MCS),NDI和冗余版本(RV)。
