Band 23 is a major FDD band which has been allocated in the US. The US regulatory rules require strict power and
emissions limits for the UE operating in Band 23 in order to protect adjacent operations below 2000 MHz [Report and Order of Proposed Modification, FCC 12-151]. A new
network-signalled value (NS_20), along with accompanying A-MPR tables, is established in TS 36.101 for Band 23 for
5, 10, 15 and 20 MHz channel bandwidths
The present document is a technical report of the work item for LTE Advanced intra-band non-contiguous Carrier
Aggregation in Band 23, which was approved at TSG RAN #60 [RP-130653]. The report provides background, analysis of the
requirements, and a list of recommended changes to the specifications.
