Description
の場合、{1008、…、65535}のうちのいずれかを導き出すために、PSCCH CRCの一部ビット(例、(nSCIDで使用した1ビットLSBの後)14ビットLSB)を利用する。上記例において、nSCIDは1ビットを使用する場合を仮定したが、より多いビット(例、2ビット或いはそれ以上)を使用してもよい。この場合、
値もnSCIDに使用するビット数に合わせて選択可能な値の範囲が変わる(例、nSCIDが2ビットを使用する場合、nSCIDは{0、1、2、3}のうちのいずれかを導き出すために、PSCCH CRCの一部ビット(例、2ビットLSB)を利用することができる。
の場合、{1008、…、32767}のうちのいずれかを導き出すために、PSCCH CRCの一部ビット(例、(nSCIDで使用した2ビットLSBの後)13ビットLSB)を利用する。この場合、cinit値もnSCID、
が選択できる値(或いは値の範囲)によって変更する必要がある。
