4, in addition to the new MTC category 0 with 1 Mbps peak data rate. There is further work expected with the UE capabilities to introduce classes up to 800 Mbps and 1 Gbps during 2015 still for Release 12. For example, with the use of 256QAM modulation in the downlink direction, the peak data rate for a single 20 MHz carrier becomes 200 Mbps, thus a UE with support of five aggregated 20 MHz carriers can reach 1 Gbps downlink peak data rate. The 3GPP can then introduce even further capabilities based on Release 12 capabilities, as with more than 2 MIMO stream then more than 200 Mbps per carrier could be enabled. In the uplink direction, the use of 64QAM in the uplink is being enabled with the addition of the capability not dependent on a particular UE category, together with the development of the relevant UE RF requirements in Release 13 (since they were missing from the Release 8 due to lack of commercial interest to uplink 64QAM at the time). With the work on-going to extend the maximum number of carrier to be aggregated up to 32 carriers in Release 13, the theoretical peak data rate in downlink direction could reach up to 32 X 200 Mbps = 6.4 Gbps with the assumption of two antenna operation, with eight-antenna operation even to 19.2 Gbps. In Release 13, new UE categories are expected to be added to specifications, especially to the upcoming Release 13 version of [13] during 2016. Conclusions In the previous sections, the enhancements for LTE Release 12 and the expected outlook for Release 13 was covered for other areas then small cells, which is captured in Chapter 4 or LTE-Unlicensed (In 3GPP term Licensed Assisted Access (LAA) for LTE being used) as LTE-Advanced Evolution in Releases 12-13 explained in Chapter 10. Release 13 is going to reflect some of the identified enhancements need, including further work in WLAN interworking as well as further D2D to facilitate better also the non-public safety use case. Some of the Release 13 items are rather clear and small, like adding the additional X2 parameters for
