XGP version 3.2(Advanced XGP)
XXGP论坛于2015年9月开发了XGP3.2）。XGP3.2描述了基于3GPP版本12的新功能，是一个更进化的系统，支持一些先进的技术，包括TDD-FDD载波聚合（TDD-FDD CA）和其他功能。
新功能可分为3组：一般增强功能、与微蜂窝相关的增强功能和与无线电服务相关的增强。每个组都包括一些高级功能，如下表所示。XGP 3.2中的关键趋势因素是更宽的频谱、增强的小蜂窝、增强的MIMO、高级架构和增强的无线电服务。
TDD-FDD载波聚合使终端联合使用TDD和FDD频谱，从而大大改善用户体验和系统容量。对于终端，聚合两个或多个分量载波（包括至少一个TDD分量载波和一个FDD分量载波），其中TDD或FDD小区可以配置为PCell（主小区）。

| Further Downlink MIMO Enhancements | Codebook & CSI enhancements to further improve 4TX performance. | |
| Small Cell related enhancements | Small cell enhancements (SCE) -physical layer aspects | 256QAM, Small cell on/off and discovery, Radio interface-based synchronization (RIBS). |
| Dual Connectivity (DC) | A UE can utilize radio resources in two distinct schedulers. | |
| Hetrogeneous Network (HetNet) Mobility Enhancements | Improve the mobility performance in HetNet deployment. | |
| Dynamic adaptation of UL:DL configuration (eIMTA) | Dynamically adjust TDD UL-DL configuration according to UL/DL traffic load ratio, interference management schemes. | |
| Inter-eNB Coordinated Multipoint (e-CoMP) | Coordinated scheduling for the scenario of multiple eNodeBs with non-ideal backhaul connections. | |
| RAN assisted WLAN interworking | E-UTRAN assisted UE based bi-directional traffic steering between E-UTRAN and WLAN for UEs. | |
| Radio Service enhancements | ProSe (Proximity-based services) | ProSe Direct Discovery and ProSe Direct Communication between Ues. |
| MBMS Minimum Drive Test (MDT) | UE collects and report MBMS measurement to help the eNB MBMS operation. | |
| Low Cost Machine Type Communication (MTC) Ues | Provides cost tailored terminals for the low-end UE market. |
