In the US, up to 194MHz is available for deployment of Band 41 based LTE TDD, with often large contiguous
(40MHz+) blocks of channels available. Further details on the specific channel and frequency block arrangement of this
band, including the regulatory requirements, are provided in TR 36.812
Many network equipment vendors are supporting, or planning to support, dual carrier, 2x 20MHz TDD radios in the
near future for the 2600MHz band.
Due to the spectrum and network equipment availability, Band 41 is a prime candidate for deployment of Release 10
based LTE-advanced carrier aggregation capable UEs.
This work item was initiated so that RAN4 could work on developing specification support for contiguous, intra-band
carrier aggregation for Band 41 to support deployment of LTE-advanced, building on the initial generic LTE TDD CA
work that is developing the framework for TDD intra-band carrier aggregation based on Band 40.
The present document is a technical report of the LTE Advanced Carrier Aggregation in Band 41 work item which was
approved at TSG RAN #52. The objective of this work item is to provide specification support for intra-band
contiguous carrier aggregation in LTE TDD Band 41.
The report provides motivation, requirements and a list of recommended changes to the specifications.
