    Abstract: Embodiments may comprise an orthogonal frequency division multiplexing (OFDM) system operating in the 1 GHz and lower frequency bands. In many embodiments, the physical layer logic may implement repetition logic to repeat portions of the data streams to increase the ability of a receiving device to detect and decode the data streams. In some embodiments, the repetition logic may comprise a preamble repeater to repeat the training and/or signal fields. In further embodiments, the repetition logic may comprise a payload repeater to repeat the payload one or more times. Other embodiments comprise a receiving device comprising a correlator to correlate the repeated preamble symbols to detect a communication from a transmitting device. The receiving device may also comprise correction logic to correct data streams from the communications signal based upon repetitions of the payload in the data streams.

    Abstract: Logic for collision mitigation between transmissions of wireless transmitters and receivers operating at different bandwidths. Logic of the receivers may be capable of receiving and detecting signals transmitted at narrower bandwidths. In several embodiments, the receivers comprise a clear channel assessment logic that implements a guard interval (or cyclic prefix) detector to detect transmissions at narrower bandwidths. For instance, a two MegaHertz (MHz) bandwidth receiver may implement a guard interval detector to detect 1 MHz bandwidth signals and a 16 MHz bandwidth receiver may implement logic to detect one or more 1 MHz bandwidth signals and any other combination of, e.g., 1, 2, 4, 8 MHz bandwidth signals. In many embodiments, the guard interval detector may be implemented to detect guard intervals on a channel designated as a primary channel as well as on one or more non-primary channels.

    Abstract: Examples are disclosed for updating a wireless communication channel estimation. In some examples, a packet may be transmitted or received via a communication channel, the packet having one or more pilot signals that may shift between subcarrier frequencies based on a predetermined first variable associated with a first time duration. A second variable associated with a second time duration may be determined by the receiver of the data packet. The second variable may enable a receiver of the data packet to decide how many pilot signals may be used to update an initial channel estimation for the communication channel. Other examples are described and claimed.

    CPC classification number: H04L27/2602 H04W72/12

    Abstract: An apparatus of a station (STA) includes memory and processing circuitry coupled to the memory. The processing circuitry is configured to encode a capabilities element for transmission to an access point (AP). The capabilities element including a media access control (MAC) capabilities information field indicating a trigger frame MAC padding duration. The processing circuitry decodes an extremely high throughput (EHT) protocol data unit (PPDU) received in response to the capabilities element. The EHT PPDU includes an EHT trigger frame (EHT-TF) in a data portion of the EHT PPDU, a packet extension (PE) field, and a dummy orthogonal frequency division multiplexing (OFDM) symbol extending the PE field. The processing circuitry performs physical layer (PHY) and MAC processing of the EHT PPDU based on a duration of the dummy OFDM symbol.

    Abstract: For example, an Access Point (AP) may be configured to configure a trigger frame to indicate an allocation of a triggered contention-based period to be allocated within a Transmit Opportunity (TxOP) of the AP. For example, the trigger frame may be configured to indicate that only one or more eligible non-AP stations (STAs), which are eligible to communicate during the triggered contention-based period, are to be allowed to contend a wireless medium during the triggered contention-based period. For example, the AP may be configured to transmit the trigger frame to initiate the allocation of the triggered contention-based period. For example, a non-AP STA may be configured to be allowed to contend the wireless medium for a transmission during the triggered contention-based period, for example, based on a determination that the non-AP STA is to be defined as an eligible non-AP STA for the triggered contention-based period.
