Abstract: Network coding by beam forming in networks, for example, in single frequency networks, can provide aid in increasing spectral efficiency. When network coding by beam forming and user cooperation are combined, spectral efficiency gains may be achieved. According to certain embodiments, a method includes operating a user equipment of a plurality of user equipment in a network comprising a plurality of access points. The method also includes the user equipment forming a beam. The method further receives processing received signals from at least one of the plurality of access points at the user equipment. The forming the beam is configured to let different user equipment of the plurality of user equipment to receive different signals from the plurality of access points to achieve diversity by using different beams amongst the plurality of user equipment. The method additionally includes cooperating with the plurality of user equipment to decode the received data.

Abstract: A method of receiving a signal in bursts including frames each including payload data and error correction data received in separate time periods, the bursts being separated by time intervals during which power is saved by disabling at least some signal processing components of the receiver, signal processing components of the receiver are disabled to save power before all the error correction data for all the frames in the burst is received.

Abstract: A method for data communication, where the data compression and decompression is performed by use of a specific hash table, by which data compression a symbol for each data segment is generated, which symbols are transmitted to the receiver where the symbols are decompressed by use of the specific hash table is modified by the specific hash table being performed as a hash table array, which hash table array generates symbols having at least a hash count and a parity check, in which hash table array the parity check comprises generating of a data string, which data string is compared with a parity stored in the hash table, where if both parities are the same, the data model returns the count in the hash table element for transmission, where a zero count is returned indicating that the data string is not valid in the hash table an no transmission is performed.

Abstract: The present invention relates to a method for data communication, where the data compression and decompression is performed by use of a specific hash table, by which data compression a symbol for each data segment is generated, which symbols are transmitted to the receiver, in which receiver the symbols are decompressed by use of the specific hash table. It is the object of the invention to perform reliably and fast data transmission between communication devices by data compression. A further object of the inventions is to perform a secure communication between computerized devices.

Abstract: A frequency resource operating apparatus and method for transmitting and receiving data at a different hopping pattern speed according to a CSI in a BWA communication system are provided. In a method of transmitting and receiving data using CSI in a mobile communication system, a BS sets the CSI of an MS to an initial CSI and sends data to the MS according to the initial CSI. The MS sends a downlink CSI to the BS. The BS groups the MS based on the downlink CSI and sends data to the MS according to a hopping pattern for the group of the MS among hopping patterns preset for predetermined groups.

Abstract: An apparatus transmits header information in a wireless communication system using a plurality of channels. In the apparatus, upon receiving uncompressed header (UCH) information, a compressor generates compressed header (CH) information and additional information container (AIC) information by compressing the UCH information with a predetermined compression scheme. A transmitter transmits the CH information through a first channel among the plurality of channels, and transmits the AIC information through at least one of the plurality of channels except for the first channel.
