Wireless Channel Estimation Using Deep Learning: A Comparison with Least Squares Method
Introduction In a wireless communication system, transmitted signals experience distortion and attenuation as they propagate through the environment. This effect is usually modelled as a linear time-invariant system with unknown channel parameters. Accurate channel estimation is essential for […]
5G SLIV – Start and Length Indicator Value
Introduction In 5G NR, SLIV means Start and Length Indicator Value. It is used for Time domain resource allocation for PDSCH and PUSCH. In SLIV, the letter ‘S’ defines the […]
PDSCH mapping – type A and type B
Introduction PDSCH is Physical Downlink Shared Channel used for User data transfer in 5G. PDSCH is transmitted with DMRS signals. In 5G NR, PDSCH scheduling is defined based on mapping […]
Approaches of Applying Deep Learning in Physical Layer
INTRODUCTION Modern communication systems have performance requirements such as large data volumes, high transmission rates, and fast response speeds, which pose challenges to existing communication technologies. Especially in the processing […]
5G NR SR – Scheduling Request
Introduction SR also known as Scheduling Request is a very famous word for telecom Dev, Test, and Optimization Engineers. It is a Layer 1 (Physical Layer) signal or message sent […]
Radio Link Monitoring in 5G – RLM
Introduction When a UE is connected to the network, it requires to continuously monitor the Radio link for reliable communication, the process is know as Radio Link Monitoring (RLM). The […]
5G NR SINR Measurement and Its Mapping
Introduction SINR is Singal to Interference Noise Ratio is a measure of signal quality. It can be defined as the ratio of wanted signal strength and the unwanted interference plus […]
5G NR Resource Allocation – Resource Allocation Type 0
Introduction To transmit and recieved data in downlink and uplink UEs need bandwidth resource allocated and this allocation provided by gNB. In 5G NR, similar to 4G the resource allocation […]
5G Carrier Aggregation – Bandwidth Classes
Carrier Aggregation (CA) increases the bandwidth by combining several carriers. Each aggregated carrier is referred to as a Component Carrier (CC). 5G NR CA supports up to 16 contiguous and […]
5G NR pdcch-ConfigSIB1 – ControlResourceSetZero & SearchSpaceZero
In 5G, during initial network access, a UE does a completes a band scan for SSB decodes the PBCH. The PBCH provides sufficient information lo allow the UE to proceed […]
