2. 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.

3. 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

4. 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.

5. 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
