The objective of this work item is to add L-Band to the appropriate 3GPP core specifications for LTE FDD networks. In addition to the schedule and status of the work items, the report includes a description of the motivation, requirements, study results and specification recommendations.
L-Band is licensed by the FCC as:
1525 - 1559 MHz: Down-link (eNodeB transmit, UE receive)
1626.5 - 1660.5 MHz: Up-link (UE transmit, eNodeB receive)
In 2003, the FCC changed its rules to permit the use of the L-band (and other bands) by satellite operators to provide
nationwide terrestrial service.
In 2004, the FCC granted LightSquared (formerly known as SkyTerra Communications and MSV) a license to reuse its
satellite spectrum to provide terrestrial service).
The Canadian government has approved similar rules to those adopted by the FCC.
Initially, LightSquared is planning on 5 and 10 MHz wide channel deployments, but this could change based on business
needs. Our LTE ATC deployment will, at least, adhere to all 3GPP terrestrial out-of-band requirements for spurious
emissions including those for UE, BS, and UE-to-UE emissions as defined in TS 36.101
for the US (i.e.
Bands 2, 4, 5, 10, 12, 13, 14, 17). Where additional requirements exist, driven by local regulatory obligations, these are
Requirements for spurious emission into L-band are expected to be the same as those required from the addition of
other new US bands in 3GPP.
