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

Dear Vladimir and All,
 
There are several messages transmitted on Broadcast CID such as NBR, PAG-ADV, TRF-IND, and so on. I want to clarify that these messages are transmitted on pre-defined DIUC (e.g. DIUC=0) in the same way as DL-MAP is transmitted. I know there is a sentence "DIUC=0 shall have burst profile parameters that are the same as those used for transmission of the DL-MAP message" in pp. 524, REVd/D5. However, in .16e, it is not clear the above broadcast messages are transmitted with DIUC=0. If it is not true, I think that an MSS in Idle Mode may not be possible to receive PAG-ADV message in the case where the BSs in the same paging group use different value of DIUC without receiving DCD message.
 
Best Regards,
 
Beomjoon

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,
