Introduction
• LBS procedure should be transparent in the
16m MAC as possible as we can since the LBS
is implemented on the application layer.
• The current 16m D1 specifies the L2 Transfer
message to support the signaling related to
LBS procedure.
• 16m shall support variable location
measurement methods.
LBS Procedure between AMS and Location server
•
Capability Negotiation
– By L2 Transfer
– Location determination method
• A-GPS
• Non-GPS
–
•
Location measurement in DL
Assistance data transfer
– By L2 Transfer message
– A-GPS
• GNSS assistance information
– DL measurement
• Geographical coordinates of candidates ABSs and the serving ABS
• Reference signal subframe information
•
Location Information transfer
– By L2 Transfer message
– AMS based location information
• Latitude/Longitude/Altitude
– AMS assisted location measurement information
• A-GPS
–
GNSS pseudo ranges
• DL measurement
–
–
ABS IDs
DL timing measurement
Proposed Text (Remedy 1)
• Replace the text in page 85, line 38 - 40
– a) Transfer-Type = 1; GNSS assistance (DL)
– b) Transfer-Type = 2; LBS measurement [Terrestrial meas.
and GNSS pseudo ranges] (UL)
With
– a) Transfer-Type = 1; LBS
• a. Sub-Type = 1: LBS capability
• b. Sub-Type = 2: LBS assistance data
– GNSS assistance information
– Geographical coordinates of candidates ABSs and the serving ABS
– Reference signal subframe information
• c. Sub-Type = 3: LBS measurement info
– AMS’ Latitude/Longitude/Altitude
– Location Measurement information
• GNSS pseudo ranges
• Terrestrial meas.
Proposed Text (Remedy 2)
• Remove all the text related to MAC procedure for
LBS in D1.
– 1) Remove the following red text in page 207, line 55
• A Paging message is an AMS notification message which either
indicates the presence of DL traffic pending for the specified AMS
or it is intended to poll an AMS and request a location update
without requiring a full network entry or to request an AMS to
perform LBS measurement.
– 2) Remove the following text in page 208, line 4
• 0b10 = Perform LBS measurement
– 3) Replace the text in page 208, line 50
– 0b10 = Perform LBS measurement
– 0b11 = Reserved
With
– 0b10 - 0b11 = Reserved
