[0052] 在MAC-hs PDU头信息中可以根据实际情况动态决定使用长度标志LF或11个比特的长度指示LI表示所复用的每一个MAC-hs SDU的长度。 [0052] The length indicator may be dynamically determined using LF or 11 bits length indication LI indicates the length of each MAC-hs SDU in the multiplexed MAC-hs PDU header information according to the actual situation. 帧结构中LF的定义可以选择使用一个比特或使用多个比特两种方式中的一种。 The frame structure defined in LF may choose to use one bit or more bits using one of two ways.

[0053] LF或LI的动态选择方法为:1)当所复用的某段MAC_hs SDU是在无线链路控制层RLC按照最大分段长度所生成的情况下,使用一个比特或多个比特的长度标志LF ;3)在一个MAC-hs PDU仅包含一个MAC-hs SDU的情况下,可以使用LF或者既不使用LI也不使用LF ;2)其它情况下,使用11个比特的长度指示LI ; [0053] The method of LF or dynamic selection of LI: 1) When the multiplexed certain MAC_hs SDU in the case of a radio link control RLC layer according to the maximum segment length generated, using a length of one bit or more bits flag LF;. 3) in the case where a MAC-hs PDU includes only one MAC-hs SDU may be used LF or LF neither nor LI; 2) in other cases, the use of 11-bit length indication LI;
