Abstract
【解決手段】本発明は、プリコーディング情報を送受信する方法およびデバイスを開示し、この方法は次を含む。端末が広帯域プリコーディングマトリックスインジケータ(PMI)を取得し、端末が、広帯域PMIの最上位ビット(MSB)を独立して符号化するか、または広帯域PMIのMSBおよびNビットの他の情報を一緒に符号化することによって、符号化情報を取得し、MSBが広帯域PMIの一部であり、Nが自然数であり、端末が、符号化情報をデータ送信端に送信する。広帯域PMIのMSBを独立して符号化し、次いでそれを送信するか、またはNビットの他の情報と一緒に符号化し、次いでそれを送信することによって、本発明の実施形態は、広帯域プリコーディング情報の信頼性を向上させ、誤り伝搬を低減し、したがってプリコーディング性能がさらに向上する。
