Rel-17 Dual Connectivity (DC) of x bands (x=1,2) LTE inter-band CA (xDL/xUL) and y bands (y=3-x) NR inter-band CA (yDL/yUL)
The present document is a technical report for Dual Connectivity (DC) of x bands (x=1,2) LTE inter-band CA (xDL/xUL) and y bands (y=3-x) NR inter-band CA (yDL/yUL) under Rel-17 time frame, including EN-DC and NE-DC. The purpose is to gather the relevant background information and studies in order to address Dual Connectivity (DC) of x bands (x=1,2) LTE inter-band CA (xDL/xUL) and y bands (y=3-x) NR inter-band CA (yDL/yUL) for the Rel-17 band combinations, where:
- For only 1 NR band included (i.e. x=2 and y=1), only NR FR2 band is applied
- For only 2 NR bands included (i.e. x=1 and y=2), 1 NR FR1 band and 1 NR FR2 band are included and operated as inter-band CA
This TR contains a general part and band specific combination part. The actual requirements are added to the corresponding technical specifications.
