QoS Mechanisms in Packet Networks There are Three Types of QoS Mechanisms in Packet Networks. Control Plane Mechanisms Data Plane Mechanisms Its Tradeoffs Control Plane Mechanisms Such mechanisms include QoS policy management, signaling, and admission control. QoS policy management is about defining and provisioning the various levels and types of QoS services, as well as … Read more
What is Beamwidth and Relation between Beamwidth and Gain What is Beamwidth? The beamwidth is also called the half power beamwidth, including horizontal beamwidth and vertical beamwidth. The horizontal beamwidth and vertical beamwidth is the beamwidth between two points where the power is lower 50% (3 dB) than the maximum radiation power. The common horizontal … Read more
The X2 interface is the interface between the eNodeBs. X2 interface protocol stack is described in Figure. X2 Interface performs the following functions: X2-UP (User Plane) X2-CP (Control Plane) LTE X2-UP (User Plane) The LTE X2-UP protocol tunnels end-user packets between the LTE eNodeBs. The tunneling function supports the identification of packets with the tunnels … Read more
Carries physical layer signaling to a single UE, such as modulation scheme (1 bit), channelization code set (7 bit), transport block size (6bit), HARQ process number (3bit), redundancy version (3bit), new data indicator (1bit), UE identity (16bit) HS-SCCH is a fixed rate (60 kbps, SF=128) downlink physical channel used to carry downlink signaling related to … Read more
