Abstract
Description
最初に第1の実施の形態について説明する。
図1は、通信システム10の構成例を示す図である。基地局装置200は、通信相手装置(図示しない)に、第1データ及び第2データを送信する。
次に、第2の実施の形態について説明する。
図2は、通信システム10の構成例を示す図である。通信システム10は、端末装置100及び基地局装置200を有する。通信システム10は、例えば、5Gに準拠した無線通信の通信システムである。また、通信システム10は、以下に示すプロトコルスタックに準拠した通信システムである。
図4は、基地局装置200の構成例を示す図である。基地局装置200は、CPU(Central Processing Unit)210、ストレージ220、DRAM(Dynamic Random Access Memory)などのメモリ230、NIC(Network Interface Card)240、及びRF(Radio Frequency)回路250を有する。基地局装置200は、例えば、URLLCのデータを端末装置100に送信する、送信装置である。
図5は、端末装置100の構成例を示す図である。端末装置100は、CPU110、ストレージ120、DRAMなどのメモリ130、及びRF回路150を有する。端末装置100は、例えば、URLLCのデータを基地局装置200から受信する、受信装置である。
図6は、データ送信処理のシーケンスの例を示す図である。基地局装置200は、データを端末装置100に送信する契機が発生すると、使用するヘッダのパターン(以降、使用ヘッダパターンと呼ぶ)を決定する(S10)。基地局装置200は、例えば、送信するデータがURLLCか否かに基づいて、使用ヘッダパターンを決定する。URLLCデータは、例えば、固定長のデータである。また、URLLCデータは、例えば、所定値より小さいデータサイズのデータであり、eMBBデータより小さいデータサイズである。
以下に、MACヘッダにおける使用ヘッダパターンの例について説明する。なお、以下のフォーマットにおける1行は1オクテットを示す。また、1オクテットは、1バイト(8ビット)として、以下に説明する。
基本パターンは、例えば、どのようなデータの送信にも使用される、汎用的なヘッダパターンである。以下、MAC基本パターンである、MACヘッダパターン1について説明する。
例えば、論理チャネルの数が少ない(例えば8本以下)の場合、データそれぞれのヘッダ部に設定されるLCIDに代替し、使用する論理チャネルをマッピングしたマッピング情報を使用する。また、基地局装置200は、URLLCが固定長である場合、データ長を省略してもよい。
基地局装置200は、URLLCが可変長である場合、データ長を付与する。基地局装置200は、例えば、N(Nは整数)個のURLLCデータを送信するとき、N-1個のデータ長を付与する。最終データの末尾は、データ長に関する情報がなくても、MAC PDCのトランスポートブロックの末尾となるためである。
基地局装置200は、使用するヘッダパターンを示す識別子を付与してもよい。例えば、基地局装置200は、使用するLCIDをそのまま設定するヘッダのパターン(例えば、図7のMACヘッダパターン1)と、LCIDに代替しマッピングした情報要素を設定するヘッダパターンを識別するビットを設ける。
基地局装置200は、URLLCが固定長である場合、データ長を省略してもよい。
通信システム10において、例えば、上記で示したヘッダを使用するLCIDを定義してもよい。
