摘要： Techniques providing opportunistic frequency switching for frame based equipment (FBE), such as may be configured to minimize opportunistic frequency switching delay in FBE new radio (NR) unlicensed (NR-U) networks and/or to provide frequency diversity FBE access based on offset sequences of medium sensing occasions for the carrier frequencies are disclosed. Within the FBE mode network, a base station may configure a pattern of sensing locations in each frame for each frequency transmission unit of the plurality of frequency transmission units, wherein an inter-unit delay of sensing locations between a first frequency transmission unit and a next adjacent frequency transmission unit and between a last frequency transmission unit and the first frequency transmission unit is a fixed duration. Opportunistic frequency switching of embodiments may utilize the medium sensing locations for opportunistically switching between a sequence of the frequency transmission units for implementing frequency diversity FBE access.

摘要： A wireless network with network-level channel hopping. A wireless network includes a wireless device. The wireless device includes a receiver, a data channel selector, and a transmitter. The receiver is configured to receive a beacon signal comprising a beacon sequence value. The data channel selector is configured to select, as a pseudorandom function of the beacon sequence value, a data channel on which to transmit in an interval following reception of the beacon signal. The transmitter is configured to transmit on the data channel selected by the channel selector.

摘要： A method includes using a first trained artificial intelligence/machine learning (AI/ML) model to identify occupied frequency channels associated with one or more incoming signals during multiple time periods, where the one or more incoming signals include a frequency-hopping spread spectrum (FHSS) signal. The method also includes generating one or more baseband signals using portions of the one or more incoming signals associated with the occupied frequency channels. The method further includes using a second trained AI/ML model to recover data from the one or more baseband signals, where the recovered data represents at least a portion of data that is encoded in the FHSS signal.
