Usage of BS index
◙ BS index is used in several cases such as
 Scanning (AAI_SCN-REQ/REP)
 Handover (AAI_HO-REQ)
 MIMO operation (AAI_MIMO-REQ)
 Feedback headers
 etc…
◙ To request system information of a specific BS within the
AAI_NBR-ADV message, the AMS need to include such
BS index in the above messages.
BS index in current NBR-ADV
◙ A BS index is included for each BS in NBR-ADV
◙ Current description of BS index inclusion in D1
 Within each cell type, a list of ABSs are provided and the following
parameters are carried for each ABS
•
•
•
•
- Index of neighbor ABS in the whole neighbor list maintained by
serving ABS
- 48bit BS-ID
- ABS A-Preamble index
- indication whether full system information or partial information is
carried for this ABS, which includes
– - SFH information
– - ESI information
– - Index to MC configuration,
Overhead reduction for BS index
◙
NBR_ABS_Index is assigned implicitly according to the order of NBR
ABS included in AAI_NBR-ADV message.


There is no need to indicate each NBR_ABS_Index for all NBR ABSs.
If AAI_NBR-ADV message is fragmented into multiple fragments, each
message fragment should contain the lowest ABS Index of the NBR ABS
so that an AMS can calculate the NBR ABS Index without the whole
AAI_NBR-ADV message fragments.
•
•
◙
If current fragment is the first fragment, the Starting BS index will be 0 for that
fragment.
Else, if current fragment is not the first fragment, the Starting BS index will be
the sequential BS index continuing from the last included neighbor BS of the
previous fragment, which can be implicitly known. Hence, the Starting BS index
of current fragment Fc will be Start BS index of F1 (first fragment) + # of BS in F1
+ # of BS Fc-1 (fragments between F1 and Fc )+ 1
Hence, if 4 fragments are present, there will be 4 BS indexes in total.
One BS index is included in each fragment.
Overhead reduction for BS index
◙ Hence, the AMS does not need to fragment number to
request any information of that specific BS, even in event
of missing fragments in between. (AMS does not need to
receive all fragments to know the index of a BS)
◙ The AMS can implicitly know the relative BS index by
referring to the Start BS index included in that fragment
◙ Overhead can be reduced for such enhanced BS index
representation
Proposed text
On the 80216m_D1, page 58 from line 18 to 28, modify text in 15.2.7.1.1 as follows:
---------------------------------------------------- Start of Text -----------------------------------------------------------15.2.6.10 AAI_NBR-ADV
…
For each fragment of the AAI_NBR-ADV, the fragment shall include the following parameters
- Starting BS Index (i.e. this is the index offset from the last BS of the previous fragment. If this is first
fragment, the Starting Index will be 0. Hence, each fragment has one Index which corresponds to the first BS in
that fragment.)
Within each cell type, a list of ABSs are provided and the following parameters are carried for each ABS
- Index of neighbor ABS in the whole neighbor list maintained by serving ABS
- 48bit BS-ID
- ABS A-Preamble index
- indication whether full system information or partial information is carried for this ABS, which includes
- SFH information
- ESI information
- Index to MC configuration,
where for macrocell type, all the necessary system information shall be included, and the format may only carry
delta information fields with respect to the reference ABS(e.g., the serving BS or the first BS/ABS in this cell type).
