21、ent of this band, including the regulatory requirements, are provided in 3.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 cand

22、idate 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 ge

At the eNB side each DL component carrier will have a corresponding UL component carrier making the aggregated BW symmetric between the DL and UL at the eNB. From

29、 the UE perspective, for an eNB operating three component carriers, the UE would only ever be aggregated on up to two adjacent carriers. According to Table 4.2-1, support for the following component carrier aggregation scenarios would therefore be required at the UE: 20+20MHz (40MHz) 15+15MHz (30MHz

30、) 20+10MHz (30MHz) 20+15MHz (35MHz)In summary, Band 41 CA capable UEs should ideally be able to support aggregated channel bandwidths of 30, 35 and 40MHz.At this time it is not proposed to further study support for 5MHz component carriers in carrier aggregation scenarios, or aggregation scenarios th
