The most feasible multiple access techniques proposed for 4G wireless communication systems that is Orthogonal Frequency and Code Division Multiplexing (OFCDM), Orthogonal Frequency Division Multiplexing (OFDM) and Multi-Carrier Code Division M...
In GSM network, the packet transmission from MS to BTS is known as uplink where as from BTS to MS is known as downlink. In GSM frequency range from 890 MHz to 915 MHz is used as uplink frequency where as 935 MHz to 960 MHz is used as downlink frequency. ReferGSM system tutorial>>...
depending on the different carriers used: i) The step of combining at least one TDD (time division duplex) carrier to one downlink or uplink FDD (frequency division duplex) carrier, also associated to uplink or downlink FDD carrier respectively; therefore, the TDD carrier would be used as FD...

In orthogonal frequency-division multiplex access (OFDMA) systems, including uplink and downlink, the carrier- frequency offset (CFO) between the multiple transceivers introduces inter-carrier interference (ICI). In this paper, we first develop the uplink-downlink duality of ICI cancellation in OFDMA...
This ranges from throughput or delay at packet data convergence protocol (PDCP) layer, down to uplink and downlink SINRs at PRB resolution, and in particular--as used in this study--the aggregated uplink inter-cell interference power as received by the base station at the center of the ...
Converting Cisco Wave 2 AP AUX Port to Downlink LAN (RLAN) Port (CLI) Some Wave 2 APs' second Ethernet port, also called the AUX port, is used as a link aggregation (LAG) port, by default. It is possible to use this LAG port as a LAN port when LAG is disabled...
Of course, the Control Software is significantly different than for the I-3 test system because of the dual frequency capability. The I-3 test system only controlled one uplink signal, although a C-Band downlink frequency was ... AJV Dierendonck,R Coker,O Razumovsky,... 被引量: 4发表:...

A method may include determining at a user equipment a need for retuning a radio frequency based on a received downlink transmission bandwidth. The method may also include determining at the user equipment a time for the retuning of the radio frequency. In addition, the method may include re...
