Physical Uplink Control Channel (PUCCH) : The Physical Uplink Control Channel, PUCCH provides the various control signalling. These signalling are known as Scheduling request, Downlink data ACK/NACK and CQI information.
Read moreIs OFDMA modulation technique?
Orthogonal frequency division multiplexing (OFDM) is a modulation technique that is used in several applications ranging from cellular systems (3GLTE, WiMAX), wireless local area networks (LANs), digital audio radio, underwater communications, and even optical light modulation.
Read moreWhat modulation does 4G use?
The digital modulation techniques used by 4G LTE networks are Quadrature Amplitude Modulation (QAM) and Quadrature Phase Shift Keying (QPSK) . Higher QAM modulation order, larger bandwidths and superior antenna techniques (MIMO) allow LTE to offer higher data rates. LTE Advanced networks use 256 QAM.
Read moreIs 5G using OFDMA?
OFDMA is already deployed in 4G and 5G . In the world of wireless LAN, the latest Wi-Fi standard (IEEE 802.11ax) uses OFDMA for both uplink and downlink data transfer. The IEEE 802.11 standard defines the commonly used wireless LAN technologies, with 802.11ax recently being released into the marketplace.
