摘要： Embodiments of an access point (AP), user station (STA), and method for variable length encoding are generally described herein. The AP may encode a block of input bits according to a parity check matrix to produce a low density parity check (LDPC) codeword. The parity check matrix may be included in a group of candidate parity check matrixes that includes a base parity check matrix and an expanded parity check matrix. An LDPC codeword length may be smaller for the base parity check matrix than for the expanded parity check matrix. The base parity check matrix may be used for the encoding when the LDPC codeword is transmitted for a legacy user station (STA). The expanded parity check matrix may be used when the LDPC codeword is transmitted for a non-legacy STA.
摘要翻译：本文通常描述接入点（AP），用户站（STA）以及用于可变长度编码的方法的实施例。 AP可以根据奇偶校验矩阵来编码输入比特块以产生低密度奇偶校验（LDPC）码字。奇偶校验矩阵可以被包括在包括基本奇偶校验矩阵和扩展奇偶校验矩阵的候选奇偶校验矩阵组中。对于基本奇偶校验矩阵，LDPC码字长度可以比扩展奇偶校验矩阵小。当为传统用户站（STA）发送LDPC码字时，基本奇偶校验矩阵可以用于编码。当为非传统STA发送LDPC码字时，可以使用扩展奇偶校验矩阵。
