Band 27 is a new FDD LTE band covering 807-824/852-869 MHz. This spectrum has previously been allocated in
Region 2, and in some countries in Region 3. Because some legacy spectrum allocations in the band are greater than 5
MHz but not integer multiples of 5 MHz, some operators are interested in Class B carrier aggregation to enable them to
more efficiently utilize their spectrum.
Building on the generic intra-band carrier aggregation work of Band 1, this work item proposes to start the work on
intra-band contiguous carrier aggregation for Band 27 to support deployment of LTE-advanced. However, this is the
first Class B carrier aggregation work item, so the generic Class B issues need to be worked.
The present document is a technical report of the work item for LTE Advanced Contiguous Carrier Aggregation in
Band 27 which was initially approved at TSG RAN #58. A revised WID was approved at TSG RAN #59. The
report provides background, analysis of the requirements, and a list of recommended changes to the specifications.
