context: The presence of the NR Synchronization Signal (SS) blocks would restrict possible options when placing a NB. Those blocks contain synchronization signals (PSS and SSS) which are used for UE to synchronize and connect to the BS. Itâs so key that NB-IoT is not overlapping those blocks to not impact NR UE synchronization performance. The SS block pattern for 15 kHz SCS is according to Case A (specified in TS 38.213 [5]) and its structure is given in Figure 5.2.1.4-1. SSB occupies 20 RBs in frequency domain and 4 OFDM symbols in time domain. Figure 5.2.1.4-1: Structure of SS Block Considering NB-IoT is currently specified only for frequency bands below 3 GHz, following equation gives the frequency position of the synchronization raster: (4.1) where is an integer, and . refers to the first subcarrier of the RB #10 of the SSB block (which corresponds to 11th RB of the SSB block). Therefore, the minimum and maximum frequencies of the SSB (i.e., SSB edges), based on Figure 5.2.1.4-2, are:
description: The Electronics Communication Committee (ECC) is an organization responsible for addressing various aspects of electronic communication. Its responsibilities include conducting studies on sharing and adjacent band compatibility between different services. In the context provided, ECC participates in decision-making processes related to IMT-2000/UMTS in specific frequency bands and coordinates with other services to ensure compatibility.
explanation: ECC is classified as an Organization because it is a body responsible for addressing electronic communication issues, making decisions regarding frequency band usage (IMT-2000/UMTS), and coordinating with other services. These functions are characteristic of organizational structures.
