Inter-cell interference coordination (ICIC) in LTE To aid downlink ICIC Relative narrowband transmission-power indicator A cell can provide this information to neighboring cells, indicating the part of the bandwidth where it intends to limit the transmission power. A cell receiving the indication can schedule its downlink transmissions within this band, reducing the output power or completely … Read more
BENEFITS OF MULTI-ANTENNA TECHNIQUES IN LTE The availability of multiple antennas at the transmitter and/or the receiver can be utilized in different ways to achieve different aims: Multiple antennas at the transmitter and/or the receiver can be used to provide additional diversity against fading on the radio channel. In this case, the channels experienced by … Read more
T-Mobile USA has announced a deal to swap blocks of radio spectrum with Verizon Wireless in 218 markets across the country. T-Mobile said the purchase will improve its spectrum position in 15 of the top 25 markets in the USA. The deal would be dependent on forthcoming Verizon spectrum purchases, currently being scrutinized by the … Read more
The MAC layer is oriented to the connections. Each connection corresponds to a service flow. The service flow defines the QoS parameters of PDU transmitted over the connection. The design core of the MAC protocol is the concept of service flow architecture on the connection. The service flow provides an uplink/downlink QoS management mechanism. An … Read more
Sub-Carrier Allocation Mode 1 DL PUSC – Downlink partial Usage Sub-Channels The downlink PUSC replacement zone is unique, that must exist in the frame structure specified by the protocols. DL PUSC with all SC – PUSC with all sc indicates the PUSC replacement mode when all the bandwidth resources are used. DL FUSC- Downlink Full … Read more

Apple promoted the “iPad with … Read more
LTE Downlink & Uplink Physical Channel LTE Downlink Physical Channel Physical Downlink Shared Channel ( PDSCH) This channel is used for unicastand paging functions. Carries the DL-SCH and PCH. QPSK,16-QAM,and 64-QAM Modulation. Physical Downlink Control Channel (PCSCH) Informs the UE about the resource allocation of PCH and DL-SCH, and Hybrid ARQ information related to DL-SCH. Carries … Read more
There are major four channel in LTE Downlink trasport channel. which list below with its work in short.Paging Channel ( PCH) Supports UE discontinuous reception (DRX) to enable UE power saving. Broadcasts in the entire coverage area of the cell. Mapped to physical resources which can be used dynamically also for traffic/other control channels. Broadcast … Read more
ZTE has launched what it says is the industry’s first LTE BeamHop Solution and demonstrated the LTE A8808 Active Antenna System (AAS) product based on this technology. Based on the LTE BeamHop Solution, the A8808 product consists of both active and passive antennae. The passive part replaces operators’ existing 2G and 3G antennae, while … Read more
Huawei today announced the successful completion of a commercial test for LTE to CDMA evolved, High-Rate Packet Data (eHRPD) optimized handoff. eHRPD means the evolution and improvement of the original CDMA EV-DO network. eHRPD acts as a bridge from CDMA to LTE by ensuring service continuity while protecting existing operator investment. In the initial … Read more
