Abstract: Embodiments of a device and method are disclosed. In an embodiment, a method of wireless communications involves at a receiver, receiving a first packet, subsequently, at the receiver, receiving a second packet, and determining whether the second packet is a repetition of the first packet based on packet acquisition information associated with the first and second packets.

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.

Abstract: RF signal is received (1006). The received RF signal includes a first RF signal encoding a first orthogonal frequency-division multiplexing (OFDM) symbol of a first long-term evolution (LTE) V2X data packet. A channel estimation in the time domain is determined (1012) using the received signal and an as-transmitted time domain version of an L-LTF symbol is determined (1014). The channel estimation in the time domain is applied to the as-transmitted time domain version of the L-LTF symbol to determine an as-transmitted version of the L-LTF symbol that exhibits channel fading (1018). A first portion of the as-transmitted version of the L-LTF symbol that exhibits channel fading is subtracted from a second portion of the received RF signal (1022) to remove inter-symbol interference from the received signal to generate a second received RF signal.

Abstract: The received RF signal includes a first RF signal encoding a first orthogonal frequency-division multiplexing (OFDM) symbol of a first long-term evolution (LTE) V2X data packet. A legacy long training field (L-LTF) symbol is determined using the received RF signal (608), a channel estimation is calculated (612) using the L-LTF symbol, and legacy signal (L-SIG) field control bits are determined (614) from the received RF signal, the L-SIG field control bits including a plurality of IQ samples. A plurality of candidate L-SIG decodings are generated (618) using the IQ samples and the channel estimation, wherein each candidate L-SIG decoding of the plurality of L-SIG decodings is generated by setting a different number of IQ samples in the L-SIG field control bits to zero values (616), and a first L-SIG decoding of the plurality of candidate L-SIG decodings is identified (624). A data field from the received RF signal is decoded using the first L-SIG decoding (626).

Abstract: Aspects of the present disclosure are directed to methods and/or apparatuses involving stations (102, 104, 105) participating in wireless station-to-station communications in which each of a plurality of stations shares a wireless communications channel (101). Information is collected wirelessly (102) from transmissions associated with a first communication protocol and from transmissions associated with a second communication protocol. A current communication environment is dynamically discerned therefrom (102), and used to characterize a dynamic relationship of the collected information, which is indicative of respective usage of the wireless communication channel by data transmitted via the respective protocols. Usage of the channel is allocated (102) for respective communications that use the first and second communication protocols based on the dynamic relationship. Sets of data (110, 111, 120, 121, 122) are wirelessly transmitted via the first and second communication protocols over the channel, based on the allocated usage.

Abstract: Aspects of the present disclosure are directed to wireless communications involving successively-received messages. As may be implemented consistent with one or more aspects characterized herein, a preamble section (122) of a currently-received message (120) is used in decoding a previously-received message (110), for wireless transmissions from a wireless transmitter (102) on a wireless communications channel (101). The current and previous message are received in succession with a time gap (130) therebetween.
