3.2.51DRCLockPeriod
【字段描述】：
連續(xù)DRCLock bit發(fā)送的時間間隔。目前共有兩個取值，8Slots或16Slots
【配置約束】：
DRCLock發(fā)送的方式如下：

If the parameter is set to 1 (16 slots), the reliability of the access terminal successfully receiving the DRCLock bit is higher due to the increased time diversity. However, the latency of the DRC Lock bit change at the AT is higher. Since the RPC Channel and the DRCLock Channel are time-division multiplexed and transmitted on the same MAC Channel, a DRCLockPeriod setting of 0 (8 slots) reduces the effective RPC Channel rate. The RPC data rate is 600 × (1 − 1/DRCLockPeriod) bps.

3.2.52DRCLockLength
【字段描述】：
表示DRCLock bit重復(fù)發(fā)送的次數(shù)，目前共有4/8/16/32四種取值。
【配置約束】：
DRCLockLength的使用詳見2.2.52對應(yīng)的DRCLock發(fā)送時序圖。
DRCLockPeriod * DRCLockLength means the transmission duration of a DRCLock bit. Long duration maybe helpful to decoding reliability but increase the latency of the DRCLock bit change which influent the fast DRC handoff and decrease the forward link throughput. However, it will eliminate false DRC re-pointing triggers due to occasional (low probability) errors on the DRC Lock channel as to less duration.

3.2.53NullRateDRC38k4En
【字段描述】：
NullRateDRC38.4Enable，表示Null速率時是否繼續(xù)以38.4K速率發(fā)包。
【配置約束】：
如果配置為1，當(dāng)AT申請Null Rate時，前向仍然以38.4的速率發(fā)包。
目前缺省為0。
