Suppressing interference in a frequency hopping signal. The method includes receiving a frequency hopping signal for a signal of interest. The frequency hopping signal includes the signal of interest modulated using frequency hopping and wideband and narrowband interference. Prior to de-hopping the frequency hopping signal, one or more wideband interferences in the frequency hopping signal are identified. The one or more wideband interferences are suppressed to create a wideband interference suppressed signal. Subsequent to suppressing the one or more wideband interferences, the wideband interference suppressed signal is de-hopped to create a de-hopped signal. In the de-hopped signal, one or more narrowband interferences are identified. The one or more narrowband interferences are suppressed to create an interference suppressed signal. The interference suppressed signal is demodulated to create a demodulated signal.

A system and method of DFT-S-OFDM modulation is provided that uses a set of frequency domain patterns. For a given transmitter, for a set of DFT-S-OFDM symbols, the frequency domain pattern changes according to a time domain hopping pattern. Advantageously, the time domain hopping patterns are defined to allow only a certain amount of overlap, for example for only one DFT-S-OFDM symbol, between any two time domain hopping patterns. This functions to reduce the effect of a collision, when two transmitters use the same frequency pattern, they will do so only for part of the overall transmission. Optionally, frequency domain spectral spreading is used in the transmitter. This can further reduce the PAPR. In the receiver, successive interference cancellation may be employed to reduce the effect of colliding transmissions.

One embodiment can provide a method and a system for performing multiple radio frequency allocation. During operation, the system including a controller can receive, a Wi-Fi channel allocation and a filter bank configuration associated with a Wi-Fi radio transceiver. The system can determine one or more Internet of things (IoT) radio transceivers operating with the Wi-Fi radio transceiver. For a respective IoT radio transceiver, the system can perform the following operations: determining a set of scores based on a set of constraints associated with an application type for the IoT radio transceiver; and computing a weighted average score based on the set of scores; and determining a channel allocation for the IoT radio transceiver based on the weighted average score and the Wi-Fi channel allocation.

A data transmitter is provided, having: a generator for generating transmission data packets, configured to split a first data packet into at least three transmission data packets, each of the transmission packets being shorter than the first data packet, the generator being configured to channel-encode the at least three transmission packets such that only a portion thereof is required for decoding the first data packet; a transmission element for transmitting data packets, configured to transmit the at least three transmission packets in a frequency channel via a communications channel with a time gap; a monitor element for monitoring the frequency channel, configured to recognize an interference or transmission of a further data transmitter in the frequency channel; the transmission element being configured not to transmit via the communications channel a packet, waiting for transmission, of the at least three transmission packets if an interference or transmission from a further data transmitter is recognized by the monitor element at the time of transmitting the transmission data packet.

Provided is a jamming defense system. In the jamming defense system for wireless local area network communication between an access point (AP) and a user node, the AP that transmits and receives a message to and from the user node generates an AP secret key value by measuring a signal reception strength for the message, and the user node that transmits and receives a message to and from the AP generates a user node secret key value by measuring a signal reception strength for the message.

Apparatus, methods, and computer-readable media for facilitating per bandwidth part TCI state or spatial relation are disclosed herein. For example, aspects disclosed herein provide techniques for enabling a UE (e.g., a reduced capability UE) to associate at least one of a TCI state or a spatial relation with respective hopping regions. An example method for wireless communication at a UE includes determining, while communicating using a first frequency range comprising a first set of frequency hops, at least one of a TCI state or a spatial relation for communicating using a second frequency range comprising a second set of frequency hops. The example method also includes communicating, after switching communication from the first frequency range to the second frequency range, using the second frequency range based on the determined at least one of the TCI state or the spatial relation.
