We may use this formula to calculate the E-field + security distances = ∙𝑃 4∙𝜋∙𝑑2 = 2 𝑍0 𝑖 [ 2] Or simplified the electric field strength at a distance d is given as: = 30∙ ∙𝑃 𝑑 in[V m] Example: calculate the E-fieldstrength for a transmitter (P TX = 14 Watt, g = 17dBi) at 50m distance:ETSI 3GPP TS 38. From these information, you. If you compare the legacy LTE and LTE BL/CE (M1) RACH procedure, LTE BL/CE is more complicated and the most of those complication comes. hR h R = height of the receving antenna. SS-RSRP is the linear average of the received secondary synchronization signals level. 1. Note that the accuracy of the PCI detection, channel estimation, and hence, 3D RSRP interpolation depend heavily on the accuracy of time/frequency synchronization and cell search procedures at the receiver. RSRP's reference point is the antenna connector of UE. rsrp-ThresholdSSBL1-RSRP: It gives the threshold to be used for determining whether a candidate beam may be used by the UE to attempt contention free random access to recover from beam failure (see TS 38. Detailed analyses were performed to investigate the relationships between RSRP, RSRQ, SINR, and CQI and evaluate their effects on THRP. 46 dB. 5 meaning minimum hysteria can be defined as 0. 1. In any technology, Measurement is done roughly at two stage. At very low RSRP of levels < -115dBm, PC3 starts to hit zero uplink throughput, and hence the gain of the uplinkCSI-RSRP (CSI reference signal received power): CSI-RSRP is defined as the linear average over the power contributions of the resource elements of the antenna ports, which carry CSI-RS configured for RSRP measurements. -44 dBm.
