Abstract: In connection with an RF communication system, exemplary aspects involve a method for use in a communication system in which a first system (e.g., 802.11) that is asynchronously based and which is susceptible to interference from a second system (e.g., synchronous-based LTE-CV2X). Such interference is due to the frequency spectrum used by the first and second systems overlapping. To mitigate interference issues, example methods spreads out the times for messages in the first system, based on information concerning occupancy of the channel, and transmitting them relative to the end of a cycled transmission allocated for use by the second system.

Abstract: A radar receiver comprising: an ADC (510) that samples analogue intermediate frequency, IF, signalling in order to generate digital signalling, wherein the digital signalling comprises a plurality of digital-values; a digital processor that populates a 2-dimensional array of bin-values based on the digital-values, such that: a first axis of the 2-dimensional array is a fast time axis and a second axis of the 2-dimensional array is a slow time axis; and a sampling-rate-adjuster that is configured to set a sampling rate associated with the bin-values in the 2-dimensional array based on an index of the slow time axis. The digital processor also performs DFT calculations on the bin-values in the 2-dimensional array along the fast time axis and the slow time axis in order to determine the range and velocity of any detected objects.

Abstract: Aspects of the present disclosure are directed to ascertaining whether data messages are repetitions of a previous data message. As may be implemented in accordance with one or more embodiments characterized herein, data packets (130/131) are received (102) and which use a first time delay relative to transmission of a previous data packet (120/121) by a different transmitter. Repetitions (110A/111A) of data packets are also received (102), and which use a second time delay relative to transmission of a previous data packet (110/111) by the same transmitter. The second time delay is less than the first time delay. The received packet is identified (102) as being a repetition of an immediately-previous data packet based on a time delay between the data packet and the immediately-previous data packet, relative to the first and second time delays.

Abstract: Aspects of the present disclosure are directed toward effecting communications in a manner that suppresses side-channel communications that may otherwise cause interference. As may be implemented in a manner consistent with one or more aspects characterized herein, an apparatus and/or method involve transmitting enhanced signals for in-band transmissions over a first one of a plurality of wireless communications channels shared by a plurality of stations for communicating wireless station-to-station communications. While transmitting the enhanced signals, communications by legacy devices on a second one of the wireless communications channels adjacent the first channel are suppressed by generating and transmitting a side channel interference signal on the second channel, therein causing legacy devices receiving the enhanced signals to withhold communications on the second channel.

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 (210, 212, 214) share a wireless communications channel. Information is wirelessly collected (213) 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 (211) 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 (216, 218, 219, 220) over the wireless communications channel using the legacy and other communication protocol, 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.

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.
