摘要: A user equipment generates information based on a plurality of values of joint coding of a Rank Index RI and a first Precoding Matrix Index W1 and transmits the information on a physical uplink control channel. The payload size of the information is 5 bits. The first Precoding Matrix Index W1 and a second Precoding Matrix Index W2 correspond to a precoding matrix and 16 values in the plurality of values correspond to the Rank Index RI of 1 or 2 where a part of values in the plurality of values except the 16 values in the plurality of values correspond to the Rank Index RI of more than 2.
摘要翻译: 用户设备基于秩索引RI和第一预编码矩阵索引W1的联合编码的多个值生成信息,并且在物理上行链路控制信道上发送该信息。 信息的有效载荷大小为5位。 第一预编码矩阵索引W1和第二预编码矩阵索引W2对应于预编码矩阵,并且多个值中的16个值对应于1或2的秩索引RI,其中除了16个值之外的多个值中的一部分值 在多个值中对应的Rank Index RI大于2。
