 likely that in a later phase new UE types will be defined (for example, for IoT use cases) 6.16 Physical Layer Measurements Table 6.18 Sub-1 GHz, 3.5 GHz, and 28 GHz downlink peak data rate calculation example.

These are also the minimum values; there may be UEs that could support even more antennas and thus be capable of an even higher data rate. With low frequency bands, such as 600 or 700 MHz, the UE is required to support only two receiver antennas, and thus the resulting data rates are naturally lower. With the bands in the range 24-29 GHz, the minimum UE-supported bandwidth is 200 MHz; thus, the resulting data rate with 4-stream MIMO would be on the order of 4 Gbps. However, the expected number of diversity streams is less, typically 2, SO the higher data rates are created by using a larger bandwidth instead of using 2-stream MIMO. With an expected allocation on the order of up to 800 or even 1000 MHz per operator, per-UE data rates on the order of 4-5 Gbps could be achieved (with multiple 200 or 400 MHz carriers). When calculating the achievable data rate, the uplink/downlink configuration will also have an impact in the case of TDD deployment. For a configuration with a large downlink allocation, a higher peak downlink data rate is naturally achieved. Table 6.18 presents an example data rate calcula
