摘要:
Apparatus and method for direct data transfer in a wireless broadband system having an operating system, the apparatus including a central processing unit (CPU), at least one dedicated Direct Memory Access unit (DMA) local to the CPU, coupled directly to the CPU, and a commands FIFO (First In First Out) receiving commands from the CPU and automatically transferring the commands in sequence to the DMA for implementation by the DMA, in the absence of intervention by the operating system.
摘要:
A femtocell including a transceiver and a processor coupled to the transceiver for implementing transmission and reception in a wireless communication network utilizing OFDM/OFDMA, and the processor including modules for collecting information about neighboring base stations and femtocells and utilizing the collected information to select the femtocell's own radio parameters, and a method for radio resource allocation in a wireless communication network implementing OFDM/OFDMA, the method including performing preamble synchronization by a sniffing femtocell on a neighboring femtocell, and determining radio resource parameters of the neighboring femtocell based on the synchronized preamble.
摘要:
A backhaul network for a mobile wireless network including a plurality of nodes forming links, the links utilizing a 1:n frequency re-use scheme in backhaul communication, where n equals 2 to about 16, wherein each link communicates over a different portion of an entire bandwidth of the network.
摘要:
A method for inserting an access point unit into a wireless telecommunications network, comprising: performing a self installation process in the access point unit, wherein during said self installation process, the access point unit automatically detects physical and RF layer parameters of access points around it, and selects its own physical and RF layer parameters according thereto, and/or performing a self-interconnection process in the access point unit wherein the access point unit contacts at least one feeder; and said feeder determines whether or not to permit connection of said access point unit to it.
摘要:
A method and point-to-point link for providing point-to-point wireless communication between a first and second node forming a link, the method including providing multiple concurrent transmissions from multiple antennas in an antenna array arrangement in the first node, controlling beam patterns of the antennas to manage deployment interference, and periodically allocating 1 to 3 MIMO (Multiple In Multiple Out) streams to different antennas in said antenna arrangement.
摘要:
A mobile broadband wireless system including at least two pairs of nodes arranged in a cluster, each pair coupled to form a link for wireless communication. Each node includes an RF transceiver with associated modem, an antenna array arrangement coupled to the modem and arranged for multiple concurrent transmissions, where each antenna has a beam pattern selected to improve quality of transmission, and a controller for controlling the transceiver, modem and antenna array arrangement for providing point to point communication. The controller allocates MIMO streams and modulation to different antennas in the antenna array arrangement, and implements at least one interference mitigation mechanism to minimize interference within the cluster during multiple concurrent transmissions. A method of wireless communication is also provided.
摘要:
A method and system for GPS (Geographical Positioning System) synchronization of a femtocell, as defined in the application, in a wireless telecommunications network, the system including a Base Transceiver Station (a “sync-BTS”) for transmitting synchronization signals, a module for GPS synchronization coupled to the sync-BTS, at least one femtocell, and a processor in each femtocell for performing time and frequency synchronization on the sync-BTS over an air interface.
