What is a user equipment (UE)?

User Equipment (UE) User Equipment (UE) refers to the end-user devices, such as smartphones, tablets, or IoT devices, that connect to the 5G Radio Access Network (RAN) for wireless communication. The UE communicates with the network infrastructure through the base station, which serves as the access point for wireless connections.

How does a wireless UE work?

First, each base station establishes the wireless channel for a subscriber's UE upon power-up or upon handover when the UE is active. This channel is released when the UE remains idle for a predetermined period of time. Using 3GPP terminology, this wireless channel is said to provide a bearer service.

UL data transmission — This is an in-band packet. The UE node transmits the UL data over the physical uplink shared channel (PUSCH) when it receives the scheduling grant. This figure illustrates the DL transmission. The DL transmission consists of these packets. CSI reference signal (RS) — The gNB node sends CSI-RSs to the UE node.

How does a UE node transmit a BSR?

The UE node transmits a BSR with a predefined periodicity as an out-of-band packet. You can use the connectUE object function of the nrGNB object to set the periodicity of the BSR report. Scheduling grant — Upon receiving the BSR from the UE node, the base station provides grants (an out-of-band packet) to the UE node for the UL transmission.

It is also possible for fault finding and commissioning teams to place the base station in a test mode where it transmits a known “test model” signal in a given direction and strength. This allows radiation patterns to be established and field strength in complex environments to be measured.

How do new base stations work?

Many new base stations utilize fiber optics from the tower base to the remote radio head (RRH) atop the tower. Short RF cables connect the RRH to the antennas. Installation teams arrive on site and conduct line sweeps on the RF cable feeds and properly align the antennas based upon MoP specifications.
