[移动通讯]【Carrier Aggregation-4】【LTE-3】

前言:

    这里面重点讲解一下跟CA 相关的  UL  UECapabilityInformation

参考：

一   UL_DCCH / UECapabilityInformation

参数	定义
supportedBandCombination	支持的CA 组合信息
CA-Bandwidth Class	ca-BandwidthClassDL-r10 d 连续聚合CC的个数
Supported MIMO for UL & DL	supportedMIMO-CapabilityDL-r10 twoLayers 动态的，不同的Band 不同
ueCapabilityInformation-r8	协议版本号
Feature Group Indicator (FGI)	'01111111 11001111 11111110 10011010'B,
ue-Category 4	定义了上下行速率以及调制方式的支持情况
accessStratumRelease：接入层版本 rel15	Rel 10 以后才支持CA

      1.1   CA-Bandwidth Class(supportedBandCombination 上下行分开配置）

            3GPP 36.101

Table 5.6A-1: CA bandwidth classes and corresponding nominal guard bands

    1.2： accessStratumRelease rel15

          接入层版本，rel10 以后才支持CA,LTE-A

         

   1.3:   ue-Category

Category终端能力等级，表明了终端所支持的数据处理能力（下载、上传速率）、最大的空分复用、调制编码能力等

        如果带上行的是PCC

                                        

       

1.5 FGI(eatureGroupIndicators )

有个在线工具： http://howltestuffworks.blogspot.com/2016/11/lte-feature-group-indicators-decoder.html

索引1是字段中最左边的一位

​跟CA 相关的是

111	Measurement reporting trigger Event A6.     This bit can be sent to 1 only if the UE supports carrier aggregation.
112	SCell addition within the Handover to EUTRA procedure     This bit can be sent to 1 only if the UE supports carrier aggregation and the Handover to EUTRA procedure.
113	Trigger type 0 SRS(periodic SRS) transmission on X Serving Cells. NOTE:X=number of supported component carriers in a given band combination.This bit can be set to 1 only if the UE supports carrier aggregation in UL.
