    • Provided is a method of transmitting channel rank information (RI) when the number of bits for transmitting the channel RI to be transmitted through a physical uplink shared channel (PUSCH) is three or more. The method includes mapping channel RI to be transmitted to a channel RI bit string of 3 bits or more, Reed-Muller coding and rate-matching the channel RI bit string using a basis sequence having a 32-bit code length, and generating modulation symbols by applying the bit sequence that has been Reed-Muller coded and rate-matched to a modulation mapper. Accordingly, the method of transmitting downlink channel RI can be employed when five or more antennas are used for downlink transmission or several carrier bands are used by carrier aggregation as specified in Third Generation Partnership Project (3GPP) long term evolution (LTE)-advanced following 3GPP LTE release 10.
    • 提供当用于发送通过物理上行链路共享信道(PUSCH)发送的信道RI的比特数为3以上时,发送信道秩信息(RI)的方法。 该方法包括将要发送的信道RI映射到3比特或更多的信道RI比特串,使用具有32比特码长的基序列的Reed-Muller编码和信道RI比特串的速率匹配,以及生成调制符号 通过将已被Reed-Muller编码和速率匹配的比特序列应用于调制映射器。 因此,当在下行链路传输中使用五个或更多个天线时,可以采用传输下行链路信道RI的方法,或者如第三代合作伙伴计划(3GPP)长期演进(LTE) - 高级跟踪中所规定的,通过载波聚合使用若干载波频带 3GPP LTE版本10。
