Read articleHow do we detect clock deviations in 5G?
This article is about Network-wide Synchronization Deviation Detection. Background. TDD networks require precise clock synchronization, as any out-of-synchronization base station can cause interference with…
Read articleHow do we deploy clocks for multimode base stations in 5G?
1. Common Clock. Common clock enables all Radio Access Technologies (RATs) in a multimode base station to share a single clock source. This reduces…
Read articleWhat are the Mainstream Clock Sources in 5G?
1. Synchronization with GNSS. Global Navigation Satellite Systems (GNSS) like GPS, BeiDou, GLONASS, and Galileo provide precise satellite-based clock solutions for base stations. GNSS…
Read articleWhat synchronization precision is required in 5G?
Synchronization precision specifies the allowable deviation between a base station’s clock and the reference synchronization source to ensure accurate operation. Per 3GPP standards: Frequency…
Read articleWhat is 5G clock synchronization and why is clock synchronization required?
5G clock synchronization ensures the proper functioning of communication networks by aligning the timing or frequency of devices. This process prevents performance issues due…
Read articleHow is the time-frequency structure of CSI-RS defined?
To read about structure of CSI-RS, you must read below. Why was CSI-RS introduced into NR? How is CSI-RS classified and what are the…
Read articleHow is CSI-RS classified and what are the functions of CSI-RS?
CSI-RS types and functions: There are 3 classifications. 1. Non-zero-power (NZP) CSI-RS Non-zero-power (NZP) CSI-RS in NR serves multiple purposes: This diverse functionality reflects…
