Re: [STDS-802-16] DCD/UCD Change in Idle Mode

Beomjoon,

MSS may be interested in the value of DCD Change Count only in the following

context: the MSS decided [for some reason] to get synch with DL transmissions from certain BS

and to be able to receive DL data e.g. wait for Paging message [the BS is not necessarily the last one where

the MSS was registered]. During that procedure, MSS waits for DCD message to get DL PHY

parameters [like DIUC meaning] and current DCD change count.

After it's done, MSS may receive further DL transmissions.

There is no need to wait for UCD unless there is an intention to transmit RNG-REQ.

Dear all,

 

Can anyone answer the question if an MSS in Idle Mode detects a different value of DCD/UCD Count in DL/UL-MAP message during MSS Paging Listening Interval, does the MSS need to wait for DCD/UCD messages without entering Paging Unavailable Interval? I think when an MSS enters Idle Mode, it does de-registration from the current Serving BS, which means it does not keep DCD/UCD Count value to which it shall refer during Idle Mode. If it is true, the MSS cannot perceive if its DCD/UCD value has been changed or not. Am I correct?

 

Best Regards,
