Abstract: Embodiments of a method and an apparatus for wireless communications are disclosed. In an embodiment, a method for wireless communications involves generating a Physical Layer Protocol Data Unit (PPDU) that includes a resource unit (RU), wherein a size of the RU is less than a signal bandwidth and wherein data corresponding to the RU is distributed onto a disjoint set of subcarriers included in a frequency unit, and transmitting the PPDU using the disjoint set of subcarriers in accordance with a power spectrum density (PSD) limit.

Abstract: A method and system comprises receiving a signal over an air interface. A binary sequence is detected in the signal. A legacy signal (L-SIG) field of a physical layer protocol data circuit (PPDU) is decoded based on the detected binary sequence and based on decoding the L-SIG field, two spoofing symbols which directly follow the L-SIG field is checked in the PPDU, wherein the two spoofing symbols comprise binary phase shift keying (BPSK) symbols. Based a presence of the two spoofing symbols, a long range portion of the PPDU is processed; and based on an absence of the two spoofing symbols, the PPDU is processed as a legacy PPDU.

Abstract: A method and system for generating an extended range (ER) physical layer protocol data unit (PPDU) is disclosed. The PPDU has a legacy portion of the ER PPDU which comprises one or more of a legacy short training field (L-STF), a legacy long training field (L-LTF), and a universal signaling (U-SIG) field and an ER portion of the ER PPDU which is appended to the legacy portion. The ER portion comprises one or more repetitions of a ER short training field (ER-STF), a ER long training field (ER-LTF), a ER-signal (ER-SIG) field, and a ER data field. In an example, signals indicative of the one or more repetitions for a same field are combined by a receiver to increase a signal to noise ratio of a field.

Abstract: A wireless network includes a client device and an access point (AP). The client device generates a data packet having a physical layer protocol data unit frame format. The client device transmits the data packet to the AP such that a plurality of long training fields (LTFs) of the data packet is transmitted at higher power as compared to a data field of the data packet, and a preamble portion of the data packet is transmitted at higher power as compared to the plurality of LTFs. Further, the data field includes various resource units (RUs) and one such RU is utilized for data transmission between the client device and the AP. The transmission of the data packet from the client device to the AP in the aforementioned manner results in the range extension of the wireless network.

Abstract: A first access point (AP) for enabling distributed multiple-input-multiple-output (DMIMO) communication in a wireless network is disclosed. The first AP is configured to select a wireless client from a plurality of wireless clients or a second AP from a plurality of APs such that a difference between a path loss value associated with the first AP and the wireless client, and a path loss value associated with the second AP and the wireless client is greater than or equal to a threshold value. The wireless client is selected when the first and second APs are available for DMIMO communication, and the second AP is selected when the wireless client and the first AP are available for DMIMO communication. The first AP is further configured to associate the first and second APs with the wireless client for enabling DMIMO communication between the first and second APs and the wireless client.

Abstract: A method for controlling communication of information includes selecting a group of stations within range of an access point, transmitting a first signal from the access point to a first station in the group, and receiving at the access point a second signal from a second station in the group. The first signal is transmitted to the first station through a downlink channel. The second signal is received from the second station through an uplink channel. Transmission of the first signal takes place during a first period and reception of the second signal takes place during a second period overlapping the first period, in order to perform full-duplex different-frequency communications based on an 802.11 standard between the access point and the first station and the second station.

Abstract: Embodiments described herein provide a system for transmitting high efficiency long term training field (HE-LTF) symbols for multiple wireless spatial streams over a wireless channel. An advanced P-matrix design is used to construct HE-LTF symbols that are processed by a receiver such that channel properties such as channel estimates or carrier phase error are determined prior to receiving all HE-LTF symbols. Tone multiplexing of wireless spatial stream is also used to transmit multiple spatial streams based on an assignment of sets of spatial streams to sets of tones available for transmission, increasing the throughput of the transmission system. The advanced P-matrix design and tone multiplexing are used in combination to achieve calculate channel properties before receiving all HE-LTF symbols while minimizing power fluctuation among the high efficiency short training field symbol and the HE-LTF symbols.
