The parameter defines the downlink power control range in relation to the maximum allocated transmission power of the radio link. The minimum transmission power is achieved by
subtracting the value of the parameter from the maximum transmission power of the radio link. However, the minimum BTS output power of the code channel defines the absolute lower limit for the minimum transmission power.
G PRACHrequiredReceivedCI -25 to -15db
This UL required received C/I value is used by the UE to calculate the initial output power on PRACH according to the Open loop power control procedure. This parameter defines the value of the IE Constant value, which is part of System Information Block 5. The value of the parameter depends on the propagation channel.

13 when UE and measurement report with Event 4A to RNC it means
有关4a 4b事件PS 业务的时候,经常会在空口消息中发现Event 4a和4b事件发生。协议上这样说：Transpot Channel Traffic Volumn exceeds absolute threshold 引起的就是PS业务的流量高于/低于一定门限值啦。比如你开始设定的是下行128k，但你只是浏览网页，根本用不了那么多，所以就会出现4b。一般4b事件触发Physical Channel Reconfiguration后导致Cell Update，手机会下滑到FACH状态。3GPP也规定，如果你不用那么大容量的信道，就要下滑到FACH状态并重配信道。可以看看UE在连接模式下的4种状态之间的转移！！这也是打开了DCCC开关后发生的现象。这个是TVM算法中的4A,4B事件，RLC层通过检测的BUFFER内的数据，来判断4A,4B事件，当然也会有一定的迟滞。商用网中，当负荷不高的情况下，我们会快速启动4A（升速），慢速启动4B（降速），主要是考虑用户感受。
DCCC 算法和状态迁移算法涉及到业务量测量，需要处理 4A和 4B 的报告。
4A报告表示待处理的业务量达到了一定门限，并且持续了一段时间，需要考虑为该业务升速。
4B 报告表示待处理的业务量低于一定门限，并持续了一段时间，可以考虑为该业务降低速率，以节省无线资源。 为了避免两套算法同时生效，设计了两个开关，当 DCCC开关打开时，状态迁移就不生效。 (4A升/4B降)

1 .what is right description of multiple access technology is wideband CDMA(WCDMA) A All cells at same carrier frequency if single carrier deployment at initial phase（最初阶段） B Separates （隔离）physical channels of users and common channels defines physical channel bit rate
C channelization cod used to separates physical channels of users and common channels defines physical channel bit rate D each carrier is 200KHZ
2.what is correct description of “incremental redundancy” in HSDPA HARQ A Re-transmitted blocks are indentical to the original block
B an erroneous block is not discarded, but is combined with sunsequent re-transmisions C each retransmission contains different redundancy version form the first transmitted data
D more re-transmission amount due to less redundancy bit
3.please choose correct description about mechanical tilting
A The resulting gain reduction depends on acimuth direction
B the horizontal half-power bean width increases with greater downtilt angle
C the horizontal half-power beam width（水平半功率波瓣宽度） is independent of downtilt angle
D there is indentical gain reduction in all azimuth direction
4.when ue in idle mode system information 11 is used to broadcast neighbor list for ue doing cell reselection however there is the limitation of SIB11,which only can include 47 neighbors in one wcel ,now you have to review the neighbor list for ADJS ADJG ADJI is not implemented due to no 2nd carrier ,what is your recommend filted to prevent hit the 47 neighbors limitation and feaisble solution
