In satellite telecommunication,a downlink is the link from a satellite down to one or more ground stations or receivers, and an uplink is the link from a ground station up to a satellite. Some companies sell uplink and downlink services to television stations, corporations, and to other telec...
Motivated by this reality, we consider the IRS-based NOMA network in the downlink and uplink scenario with a pernicious eavesdropper. Moreover, we investigated the physical layer security (PLS) of the proposed system by invoking the connection outage probability (COP), secrecy outage probability (...
Cell association in cellular networks has traditionally been based on the downlink received signal power only, despite the fact that uplink and downlink tr... H Elshaer,F Boccardi,M Dohler,... - Global Communications Conference 被引量: 111发表: 2015年 DOWNLINK CONTROL IN HETEROGENEOUS NETWORKS ...
V Visoottiviseth,A Trunganont,S Siwamogsatham - 《Eurasip Journal on Wireless Communications & Networking》 被引量: 5发表: 2011年 Differentiating Contention Window for Fairness of Uplink and Downlink in Error-Prone IEEE 802.11 WLAN This paper proposes a scheme for fairness between uplink and d...
This paper proposes practical coordinated linear transmit-receive processing schemes for the uplink (UL) of multiuser multiple-input multiple-output (MIMO) systems in the time division duplex (TDD) mode. The base station (BS) computes the transmission pa
In satellite communications, downlink simply refers to the process when a satellite beams down information toward earthbound terminals or devices. The opposite of this is uplink, where the satellite receives data from an earthbound terminal. In cellular networking, downlink can be seen from the user...
AW916-GL LGA WiFi 6 & BT5.1 Module supports WiFi6 IEEE802.11 A/B/G/N/AC/AX standard and BT5.1 standard for smart car networking $36.00 - $66.00 Min. order: 1 piece The SC20-AL is a new-generation multi-mode LTE Cat 4 smart module,Max. 150Mbps downlink / 50Mbps uplink under ...
In this paper, we study the problem of energy-efficient downlink and uplink data transmission between mobile devices and clouds. In the presence of unpredictable data arrival, network availability and link quality, our objective is to minimize the time average energy consumption of a mobile device...
(RNC) of the mobile communication system to arrange for the second base station to serve the user equipment in only the uplink direction, wherein the one or more communicated control signals include uplink transmit parameters to be used when serving the user equipment and include an instruction...
