Abstract: Systems and methods for performing listen-before-talk (LBT) operations include a first wireless communication device which schedules a data burst comprising a plurality of chirps for transmitting on a channel to a second device. The wireless communication device may perform an LBT operation on the channel between the first device and the second device to determine that the channel is available, prior to transmitting a first chirp of the plurality of chirps. The wireless communication device may transmit the first chirp on the channel responsive to performing the LBT operation.

Abstract: Described embodiments provide devices and methods for directing portions of signals to reduce power consumption. A wearable device may comprise N antennas configured to wirelessly receive and/or transmit incoming and/or outgoing signals. The N antennas may be spatially disposed on the device to enable at least one of the N antennas to be clear from blockage by a body part of a user when the device is maintained or worn against the body part, wherein N is an integer value greater than or equal to 2. The wearable device may comprise N receive chains coupled to the N antennas via transmit-receive couplers, the N receive chains configured to process the incoming signals. The wearable device may comprise a transmit chain configured to generate the outgoing signals. The wearable device may comprise a RF controller circuitry configured to direct portions of the generated outgoing signals via the transmit-receive couplers to the N antennas.

Abstract: Systems and methods for data transmission within the ultra-wideband ranging protocol include a first UWB device which determines a transmission block comprising a plurality of rounds each representing a period of time. The first UWB device performs a first wireless communication to perform ranging between the first UWB device and a second UWB device, within a first round of the plurality of rounds. The first UWB device may perform a second wireless communication to communicate data between the first UWB device and the second UWB device, which may be within the first round or a second round.

Abstract: A wireless communication device may include one or more processors. The one or more processors may transmit one or more first request frames to a wireless communication node and a wireless user device. The one or more first request frames may indicate to the wireless communication node to perform a first transmission to the wireless communication device during a first service period (SP). The one or more first request frames may indicate to the wireless user device to perform a second transmission to the wireless communication device during the first SP. The one or more processors may receive, during the first SP, according to the one or more first request frames, the first transmission from the wireless communication node, and the second transmission from the wireless user device.

Abstract: Disclosed herein are aspects related to a device that can include a wireless communication interface and one or more processors. The wireless communication interface can transmit, using a wireless connection with a remote device, one or more data elements to the remote device. The one or more processors can identify a condition of the wireless connection, determine a rate, for transmission of the one or more data elements, based at least on the condition, retrieve a signal from the remote device indicative of at least one criterion for use of the one or more data elements, update the rate based at least on the at least one criterion to determine an updated rate for transmission of the one or more data elements to the remote device, and cause the wireless communication interface to transmit, at the updated rate, the one or more data elements to the remote device.
