摘要： A method for an electronic device includes determining, based on indicating information of an uplink pilot sequence allocated by a base station, an uplink pilot sequence, transmitting the uplink pilot sequence, and determining a change in a geographical location of the electronic device. In a case that the geographical locations of the electronic device before and after changing correspond to different cell partitions, the uplink pilot sequence is updated based on the indicating information allocated by the base station, and the updated uplink pilot sequence corresponds to the cell partition corresponding to the geographical location of the electronic device after changing. The uplink pilot sequence is for the base station estimating a channel between the base station and the electronic device, and filtering based on the geographical location of the electronic device during the channel estimation, to obtain a channel estimation result matching the electronic device.

摘要： A communication system including a first station having at least two first narrow beam antennas and a second station having at least two second narrow beam antennas. The first and second stations establish a first communication path for wireless communication via a pair of first and second narrow beam antennas. When communication via the first communication path is disturbed by obstacles, the first and second stations automatically establish at least one alternative communication path, which is spatially different from the first communication path, for wireless communication using the at least two first narrow beam antennas and the at least two second narrow beam antennas.

摘要： A heterogeneous wireless network topology suited for low-power, short-range and ubiquitous ad-hoc communication. The network topology integrates different wireless transmission technologies, in particular to a wireless sensor network including different node types and communication technologies. The network is highly heterogeneous and can be operated according to the master-slave principle. The nodes can have different wireless communication means tailored to their individual role in the network and other constraints, thus allowing different communication patterns.

摘要： The present invention relates to a transmitting device and a receiving device in a wireless orthogonal frequency division multiplex (OFDM) communication system with space time transmit diversity (STTD). Further, the present invention relates to a channel estimation method for performing a channel estimation in such a wireless communication system, in which the transmitting device comprises a first and a second antenna for transmitting signals with space time transmit diversity. The first and the second antenna means are arranged spaced apart from each other in a space diversity arrangement, whereby first and second pilot symbols are transmitted via said first and said second antenna means, respectively. Some of the second pilot symbols are orthogonal to corresponding ones of the first pilot symbols, so that a channel estimation to separately determine the transmission quality of signals transmitted from the first and the second antenna means, respectively, can be performed in a receiving device which receives the signals with only one single antenna.
