Hello, I have questions. UCD and DCD is assigned uplink/downlink channel IDs.
Under these channel IDs, a list of UIUC/DIUC and corresponding burst
profiles is associated. The standard does not explicate the motivation of having
defined these IDs. The standard says “This identifier is
arbitrarily chosen by the BS and is only unique within the MAC-Sublayer domain. It also describes how
to obtain uplink parameters that begins with reading out channel ID field and then check for channel
usability for the channel ID. SS would lose synchronization with uplink channel when UL-MAP or
UCD were not received within expiration time. So, I guess by altering channel ID BS might be able
to induce SS’s synchronization procedure. But I might have missed the target? What does “unique within the MAC-Sublayer
domain” mean? Does it imply the uniqueness of ID within a cell? CHO
