Wideband micro sleep techniques

Methods, systems, and devices for wireless communications are described. In a wireless communications system, a first user equipment (UE) may receive a message from a second UE via a set of one or more antennas, where a first symbol period and a second symbol period of the message include a duplicated signal, and the first symbol period is immediately prior to the second symbol period in a time domain. The first UE may calculate a correlation between first data included in the first symbol period and second data included in the second symbol period of the message for each antenna of the set of one or more antennas. In some cases, the first UE may power down at least one radio frequency chain based on the result of the calculated correlation satisfying a threshold value.

Microwave oven coexistence with Wi-Fi/BT

A wireless communication device and method for operating the same for mitigating interference in a wireless communication network are provided. Generally, the method includes sensing with the wireless communication device pulses of electromagnetic radiation recurring within a band of frequencies used by the device for communication of signals, identifying the pulses as interference, and determining a number of frequencies of the interference within the band of frequencies used by the wireless communication device. Next, a sensitivity of the wireless communication device is reduced upon sensing one of the pulses and repeated at a frequency corresponding to the frequency of the interference. Thus, a spectrum of electromagnetic radiation around the wireless communication device is perceived by the device as free of interference, enabling it to transmit and/or receive more often. Other embodiments are also disclosed.

Delayed Preamble Detection for Bluetooth Receiver based on Interferer Metric
20230046497 · 2023-02-16 · ·

The present invention relates to a method and apparatus for reducing power consumption in a receiver of a time slotted communication system. An RF front end has power applied after the start of a preamble or after the start of a header, or upon the start of a packet payload based on connection status, signal level, and interference level. Where the signal level is constant, the communication system is in a connected state, and the interference level is low, the system bypasses packet header destination address matching, or optionally, uses only the least significant bits of the header destination address for matching purposes.
