Method And Device In Ue And Base Station For Wireless Communication

How does a base station work?

Figure 3.5: Base station establishes one or more tunnels between each UE and the Mobile Core's User Plane. Fourth, the base station forwards both control and user plane packets between the Mobile Core and the UE. These packets are tunnelled over SCTP/IP and GTP/UDP/IP, respectively.

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.

What is a baseband unit (BBU)?

Baseband Unit (BBU) The baseband unit (BBU) plays a vital role in transmitting data from the RAN node to the core network and relaying data received from the core network to the radio unit for further transmission.

What is ul data transmission?

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.

How to switch off inverter when not in use?

To know how to switch off inverter when not in use you have two options. The first option is through the bypass by using the bypass switch on the back of the inverter.

How do I Turn my inverter back on?

Once the waiting period is over, you can proceed to turn the inverter back on. If you used the power button, simply press it again. If you turned off the AC disconnect switch, switch it back on. After powering up the inverter, observe the display panel for any error messages or indicators.

How do I connect a DC inverter to a meterbox?

Step 1: Locate your meterbox or switchboard and locate the "main switch inverter supply" and turn that to the OFF position. Step 2: Go to your inverter and locate the DC isolator. (Some times there will be a DC isolator to the LEFT of the inverter, most of the time it will be an inbuilt switch on the bottom of the inverter or sometimes both.)

How do I Turn on or shut down my inverter?

A step by step guide for turning on, shutting down or restarting your inverter safely. Step 1: Locate your meterbox or switchboard and locate the "main switch inverter supply" and turn that to the ON position. Step2: Go to your inverter and locate the DC isolator.
