Abstract: A first-transceiver system for use in an antenna diversity scheme. The first-transceiver system comprising: a first-receiver; a first-time/clock-generation-unit; a first-transmitter; and a timing-controller. The first-receiver is configured to receive a wireless first-common-signal from a third-party-transmitter, wherein the first-common-signal is representative of a common-signal transmitted by the third-party-transmitter. The timing-controller is configured to: receive signaling representative of the first-common-signal; receive signaling representative of a wireless second-common-signal as received at a second-transceiver, the wireless second-common-signal being representative of the common-signal; and generate a timing-signal based on the first-common-signal and the second-common-signal. The first-transceiver system is configured to set the first-time/clock-generation-unit, based on the timing-signal, to reduce an alignment-error between the first-time/clock-generation-unit and the second-time/clock-generation-unit. The first-transmitter is configured to transmit a wireless first-transmission-signal, in accordance with the first-time/clock-generation-unit, as part of the antenna diversity scheme that comprises aligned transmission of both the first-transmission-signal and a second-transmission-signal.

Abstract: Embodiments are directed to methods and apparatuses for wireless vehicular communications involving retransmission of messages. A method for communicating by vehicular communications circuitry of a device includes, in a wireless communications network in which a message is broadcasted by vehicular communications circuitry of a device for asynchronous receptions by other circuitry in one or more devices configured to wirelessly communicate according to a communications protocol, monitoring a channel busy ratio associated with channels in a designated range of frequency pertaining to the wireless communications network. The method further includes assessing whether to retransmit the message as a function of the channel busy ratio, and in response to the channel busy ratio being outside a threshold, retransmitting the message according to the communications protocol.

Abstract: A method and apparatus are provided in which receiver circuitry and signal processing circuitry may reside. The receiver circuitry receives a FMCW radar signal having a content signal (e.g., a random or information signal) embedded into a radar waveform and indicating a relationship in the FMCW radar signal between beat frequency and time delay. The signal processing circuitry may apply a filter (e.g., filtering with a group delay that approximates or relates to the relationship) that causes a residual error in, due to dispersion of, the content signal, and may account for (e.g., mitigate) the residual error by introduction of a dispersion-related function in further processing of the content signal.

Abstract: Aspects of the present disclosure are directed to radar signaling utilizing a non-uniform multi input/multi output (MIMO) antenna array including first and second uniform MIMO antenna arrays respectively having both sparsely-arranged transmitting antennas and sparsely-arranged receiving antennas. Communication circuitry is configured to determine a direction of arrival of reflections of radar signals transmitted by the transmitting antennas and received by the receiving antennas, by comparing the reflections received by the first MIMO array with the reflections received by the second MIMO array during a common time period (e.g., at the same time). Using this approach, the antenna arrays may be utilized to provide co-prime spacing/elements and to suppress ambiguities in received reflections based on alignment thereof.

Abstract: Aspects of the disclosure are directed to methods and apparatuses for wireless vehicular communications involving the transmission of messages using two or more protocols. As may be implemented in accordance with one or more embodiments characterized herein, wireless station-to-station communications are carried out in which a plurality of stations share a wireless communications channel. Information is wirelessly collected respectively from transmissions associated with a legacy communication protocol and another type of communication protocol. A current communication environment of the station is dynamically discerned and characterizes a dynamic relationship of the collected information using the legacy communication protocol relative to the collected information using the other communication protocol. Communications are wirelessly transmitted over the wireless communications channel using the legacy and other communication protocols, by allocating usage of the channel through transmissions of data, via the legacy communication protocol and via the other communication protocol, based on the dynamic relationship.
