tion that is valid for a Release 15 UE supporting the 3.5 GHz frequency band (Band n78) as well as an example with the 28 GHz band. Physical Layer Measurements The physical layer measurements reported by the UE toward the network are typically based on either the Secondary Synchronization (SS) signal or on the CSI-RS. Naturally, 6 5G Physical Layer for the use with mobility toward LTE, additional LTE measurements based on LTE RSRP are supported. For measurements within the 5G network, the following measurement are defined in [6]: Synchronization Signal reference signal received power (SS-RSRP). This is based on the REs carrying the SSS. Synchronization Signal reference signal received quality (SS-RSRQ), which can be defined as the SS-RSRP/NR carrier Received Signal Strength Indicator (RSSI). Synchronization Signal signal-to-noise and interference ratio (SS-SINR). The linear average over the power contribution (in [W]) of the REs carrying the SSSs divided by the linear average of the noise and interference power contribution (in [W]) over the REs carrying the SSSs within the same frequency bandwidth. SS reference signal received power per branch (SS-RSRPB), which is the linear average over the power contributions of the REs that carry the SSSs. CSI reference signal received quality (CSI-RSRQ). CSI signal-to-noise and interference ratio (CSI-SINR): BTS side: SSS transmit power. During network planning, one should avoid not only using the same physical cell ID in close proximity, but also avoid using the same SSS sequence in the near-by cell as the UE measurements may get corrupted due to the same sequence coming from two synchronized base stations. 6.17 UE Capability Unlike in LTE, 5G does not define specific UE categories to determine the maximum data rate capabilities. The approach chosen in Release 15 was to let the supported fre- quency band determine what kind of data rates to be supported. This is derived basically by taking into account the following: Minimum bandwidth supported for a given band Number of re
