by using an uplink and downlink configuration specific to the secondary cell; measuring radio interference on a temporarily set uplink related carrier on the secondary cell based on information on the temporarily set uplink related carrier received on a downlink related carrier on the primary cell;...
下图是3GPP关于载波聚合从Re-10到Re-12的定义历程。 3GPP Rel-10定义了bands 1 (FDD) 和 band 40 (TDD)的intra-band 连续载波,分别命名为CA_1C 和CA_40C。同时还定义band1和5的inter-band载波聚合,命名为CA_1A-5A。 3GPP Rel-11定义了更多CA配置,如下图: ………(篇幅有限,更多请下载文档浏览) 下载...
There are many frequency bands allocated in available spectrum for LTE (FDD & TDD) which are numbered and have defined limits.

LTE Advanced Pro (LTE-AP)specifications were released in 2016 and 2017. LTE Advanced Pro includes three major technical innovations: 1) carrier aggregation, which uses spectrum from different LTE carrier bands, 2) Higher-order modulation, which uses available spectrum more efficiently by carrying mor...
3GPP Rel-10定义了bands 1 (FDD) 和 band 40 (TDD)的intra-band 连续载波,分别命名为CA_1C 和CA_40C。同时还定义band1和5的inter-band载波聚合,命名为CA_1A-5A. 连续CA带宽等级和保护带宽: 载波聚合中单个载波称为CC(component carrier). ...

Once a carrier has the spectrum, it can begin upgrading subnets of its networks, piece by piece. The hardware that's replaced generally isn't the cell tower equipment that you see by the highway or on tall buildings. Instead, engineers start by replacingroutersand servers to new versions th...
