    • In one embodiment, a method for transmitting information includes processing a downlink transport channel to generate a transport block (TB) having a TB size. The TB size is selected by selecting a modulation and coding scheme index ( I TBS ) and a physical resource block index ( N PRB ). The TB size for the selected I TBS and N PRB is selected so that an effective code rate at an user equipment (UE) does not exceed a specified threshold. The effective code rate is defined as a number of downlink (DL) information bits including TB cyclic redundancy check (CRC) bits and code block CRC bits divided by a number of physical channel bits on Physical Downlink Shared Channel (PDSCH). The transport block is mapped to multiple spatial layers. The number of spatial layers N is greater than or equal to three. The multiple spatial layers are transmitted to the UE.
    • 在一个实施例中,一种用于发送信息的方法包括处理下行链路传输信道以生成具有TB大小的传输块(TB)。 通过选择调制和编码方案索引(I TBS)和物理资源块索引(N PRB)来选择TB大小。 所选择的I TBS和N PRB的TB大小被选择为使得用户设备(UE)的有效码率不超过指定的阈值。 有效码率被定义为包括TB循环冗余校验(CRC)比特和码块CRC比特除以物理下行链路共享信道(PDSCH)上的物理信道比特数的下行链路(DL)信息比特数。 传输块被映射到多个空间层。 空间层数N大于或等于3。 多个空间层被传送到UE。
