    Abstract: A signal time delay estimation method includes: obtaining, at an apparatus, a plurality of RFFPs (radio frequency fingerprints) each based on a plurality of signal measurements of respective signals transferred between respective ones of a plurality of wireless signal transfer devices; obtaining, at the apparatus, a plurality of locations corresponding to the plurality of wireless signal transfer devices; and implementing, at the apparatus, a machine-learning algorithm to provide at least one first indication of at least one first signal time delay to convert between a first wireless signal at a target device, of the plurality of wireless signal transfer devices, and a first baseband signal at the target device based on the plurality of RFFPs and the plurality of locations.

    Abstract: A method of wireless communication performed by a first transmission device incudes receiving a first set of observations from a first receiving device based on transmissions from the first transmission device to the first receiving device at a previous time slot of a fixed contention-based spectrum sharing system. The first transmission device shares a spectrum with a second transmission device. The method also includes measuring an energy level from an ongoing data transmission of the second transmission device at a current time slot. The method further includes generating, at an artificial neural network of the first transmission device, at least one of a transmission determination, a set of transmission parameters, or a combination thereof, based on a second set of observations, the energy level, and a counter. The method also includes transmitting, to the first receiving device, during the current time slot based on at least one of the transmission determination, the set of transmission parameters, or the combination thereof.

    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a base station transmitting to a user equipment (UE) a partial bandwidth configuration for uplink transmissions, where the partial bandwidth configuration may indicate a channel interlace and a portion of a channel bandwidth, for example, for autonomous uplink (AUL) transmissions. The base station may also transmit to the UE an AUL configuration including a group identifier. The UE may determine a starting offset with respect to an AUL subframe for a partial bandwidth transmission based on the group identifier. In some cases, different UEs may be grouped into groups of UEs allocated non-overlapping resources, and UEs allocated overlapping resources may have different starting offsets to begin transmitting. According to the determined starting offset, the UE may perform the partial bandwidth transmission over the channel interlace and the portion of the channel bandwidth.
