Technologies for dynamic wireless noise mitigation include a computing device having a wireless modem and one or more antennas. The computing device activates one or more components of the computing device, monitors platform activity, and measures wireless noise received by the antennas. The computing device trains a noise prediction model based on the platform activity and the measured noise. The computing device may monitor platform activity and predict a noise prediction with the noise prediction model based on the monitored activity. The computing device may mitigate wireless noise received by the wireless antennas based on the noise prediction. The computing device may provide the noise prediction to the wireless modem. Other embodiments are described and claimed.

A wireless communication system with scalable diversity and multi-transceiver diversity deployment is disclosed. An example communication system includes a first wireless transceiver, having a first bandwidth and a first center frequency, a second transceiver, having a second bandwidth and a second center frequency, and a processor. The processor is configured to operate the wireless communication system in a first mode when a difference between the first center frequency and the second center frequency is greater than or equal to half of the first bandwidth plus the second bandwidth. The processor is also configured to operate the wireless communication system in a second mode when a difference between the first center frequency and the second center frequency is less than half of the first bandwidth plus the second bandwidth.

A wireless communication device may autonomously transition from a multiple antenna port mode to a single antenna port mode. The wireless communication device may implicitly notify a base station about the autonomous transition from the multiple antenna port mode to the single antenna port mode. The base station may reallocate resources that were previously allocated to the wireless communication device but that are no longer being used by the wireless communication device. In some cases, the base station may configure the wireless communication device's antenna port mode via radio resource control signaling.

Provided is a frame configuration usable for both SISO transmission and MISO and/or MIMO transmission. A frame configurator of a transmission device configures a frame by gathering data for SISO and configures a frame by gathering data for MISO and/or MIMO data, thereby to improve the reception performance (detection performance) of a reception device.

A communication satellite includes user beam antennas capable of forming user beams and feeder beam antennas capable of forming feeder link beams. The communication satellite includes demultiplexing units that divide a reception signal into up-user-link signals, multiplexing units that multiplex input signals and output the signals to feeder beam antennas, and a switch that duplicates an up-user-link signal on the basis of information determined for each of the up-user link signals and indicating whether the user link signal is duplicated, generates a duplicated signal, and outputs the duplicated signal and the up-user-link signal to the multiplexing units corresponding to second beams respectively allocated to the duplicated signal and the up-user-link signal.

Techniques are presented herein for computing angle-of-arrival estimates while switching antenna states during a packet unit for the general Orthogonal Frequency Division Multiple Access (OFMDA) case (including a single user). A wireless device computes channel estimates throughout the entire frame and not only during the training symbols. Consequently, the wireless device computes channel estimates for all antennas in its array within a single frame instead of having to wait for multiple frames.

All data symbols used in data transmission of a modulated signal are precoded by hopping between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol in the frequency domain and the time domain all differ. A modulated signal with such data symbols arranged therein is transmitted.

An measurement method and a terminal, where the method includes: determining, by a first antenna selection module in terminal, at least two measured antennas, setting the at least two measured antennas as a first measurement antenna, adding the first measurement antenna to an occupied antenna set; determining measurement duration of the first measurement antenna; performing a measurement operation on the first measurement antenna; determining, by a second antenna selection module, a second measurement antenna and measurement duration of the second measurement antenna based on the occupied antenna set and the measurement duration of the first measurement antenna, adding the second measurement antenna to the occupied antenna set; performing a measurement operation on the second measurement antenna; and determining, a measurement result of the first measurement antenna and a measurement result of the second measurement antenna when the measurement duration of the first measurement antenna ends.

A packet data transmission system comprises primary stations (PS) having signal transmitting and receiving means and antennas (PA1 to PA4) for propagating downlink signals and receiving uplink signals and a plurality of secondary stations (SS) able to roam within the coverage areas of the primary stations. Each secondary station (SS1) has signal transmitting and receiving means, a predetermined number of antennas (SA1 to SA4), and means for monitoring its radio environment. Information about the radio environment is relayed as an uplink signal to the respective primary station which modifies its mode of transmission of packet data signals. The secondary station in response to the modified mode of transmission of the downlink signals adapts its receiver resources to process the packet data signals and effect cancellation of any interference.
