Detailed Description

The example embodiments described herein provide certain systems, methods, and devices for providing signaling information to Wi-Fi devices in various Wi-Fi networks according to the IEEE802.11 communication standard, including but not limited to IEEE802.11 ay.

The following description and the drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may include structural, logical, electrical, process, and other changes. Portions or features of some embodiments may be included in or substituted for those of others. Embodiments set forth in the claims encompass all available equivalents of those claims.

As mentioned above, various standards are being developed for the millimeter (mm) wave (e.g., 60GHz) band of the spectrum, such as Institute of Electrical and Electronics Engineers (IEEE)802.11 ay. One such standard is, for example, ieee802.11 ay. IEEE802.11ay is related to the IEEE802.11 ad standard (also known as WiGig). IEEE802.11ay seeks, in part, to increase the transmission data rate between two or more devices in a network.

As used herein, in embodiments, Orthogonal Frequency Division Multiplexing (OFDM) may refer to a Frequency Division Multiplexing (FDM) scheme used as a digital multi-carrier modulation method for network communications. In one embodiment, in OFDM, a plurality of closely spaced orthogonal subcarrier signals may be used to carry data over several parallel data streams or channels. Each subcarrier may be modulated with a legacy modulation scheme (e.g., quadrature amplitude modulation or phase shift keying) at a relatively low symbol rate, thereby maintaining a total data rate similar to legacy single carrier modulation schemes at the same bandwidth.

As used herein, in embodiments, a subcarrier may refer to a sideband of a radio frequency carrier that is modulated to transmit additional information over a communication channel in a network.

As used herein, in embodiments, a Direct Current (DC) subcarrier may refer to a subcarrier on which no information is transmitted. In one embodiment, the mobile device may use the DC subcarrier to locate the center of the OFDM band.

As used herein, in embodiments, a pilot signal may refer to a signal that is typically transmitted at a predetermined frequency on a communication system, e.g., for supervision, control, equalization, continuity, synchronization, and/or reference purposes. In one embodiment, the pilot subcarriers may be used to track phase residuals associated with one or more subcarriers, for example, after frequency correction is achieved.

As used herein, in embodiments, Channel Bonding (CB) may refer to the practice used in IEEE802.11 implementations, where two adjacent channels within a given frequency band are combined to increase throughput between two or more wireless devices. Channel bonding may enable increased throughput and provide more functionality within a Wi-Fi deployment. In IEEE802.11 n, CB may occur when two adjacent 20MHz channels within a particular frequency are joined to produce one 40MHz channel, thereby doubling the throughput between wireless devices. In fact, the CB in this case can make the channel size more than double because the guard band is removed. Furthermore, since the first standardization of IEEE802.11 in 1997, many Wi-Fi devices operate at 2.4GHz frequency. Although many Wi-Fi devices may operate in both the 2.4GHz and 5GHz frequency bands, in many applications, 2.4GHz is preferred because of its greater range than 5 GHz. In addition, since 2.4GHz exhibits a rather slow speed, CB can be used to improve device performance.

In one embodiment, the present disclosure describes definitions and parameters for use in connection with OFDM signal spectrum. In another embodiment, the present disclosure extends to definitions and parameters for use in connection with OFDM signal spectrum with channel bonding. In one embodiment, the present disclosure describes the number of data subcarriers, pilot subcarriers, Direct Current (DC) subcarriers, and Guard Band (GB) subcarriers used in conjunction with an OFDM signal spectrum. Further, as mentioned, the present disclosure describes OFDM signal spectrum definitions for networks implementing single-input single-output (SISO) transmission with channel bonding. In some embodiments, the systems and methods described herein may be implemented with directional antennas (e.g., Phased Antenna Arrays (PAAs)).

In one embodiment, for channel bonding used in conjunction with an EDMG OFDM spectrum, the subcarrier spacing may be used as an EDMG OFDM spectrum defined, for example, in one or more legacy standards (e.g., legacy 802.11ad standards). In one embodiment, such a criterion may specify that the frequency spectrum is approximately equal to Δ f-5.1563 MHz. In one embodiment, the DFT size used in conjunction with channel bonding may be defined as 512N_CBWherein for 2, 3 and 4 channels, respectively N _CB2, 3 and 4. In one embodiment, the number of total occupied subcarriers for channel bonding may be defined in the following manner: edge spectrum subcarriers (i.e., subcarriers whose frequencies are on the edges of the spectrum) do not exceed the boundaries of another transmission in a nearby frequency range. In one embodiment, a center frequency for channel bonded transmissions may be selected based at least in part on a variety of factors, including but not limited to subcarrier spacing, channel bonding factors, and/or definitions and/or recommendations described by one or more standards. In one embodiment, the number of data subcarriers may be a predetermined number and may be used to support interleaving on Low Density Parity Check (LDPC) codewords, e.g., for higher order modulation. In one embodiment, a Low Density Parity Check (LDPC) code may refer to a linear error correction code that may be used to transmit messages over a noisy transmission channel.

In one embodiment, the number of DC subcarriers may be fixed, e.g., N _DC3, regardless of the channel bonding factor used for channel bonding. In another embodiment, channel bundling factor N may be based at least in part on_CBTo modify the number of DC sub-carriers; further, the remaining subcarriers (i.e., subcarriers other than the DC subcarrier) may be divided between the left and right Guard Bands (GB).

In one embodiment, channel bonding may be performed; thereafter, one or more GB subcarriers having frequencies between the channel and the DC subcarrier may be reused for data subcarrier and/or pilot subcarrier transmission. In one embodiment, the predetermined number of extra childrenCarriers (e.g., 66 additional subcarriers) may be used for channel bonding of two channels, 66 × 2 ═ 132 additional subcarriers may be used for channel bonding of three channels, and 66 × 3 ═ 198 subcarriers may be used for channel bonding of four channels. In various embodiments, the total number of occupied subcarriers N_totalCan be written as: n is a radical of_total＝352×N_CB+N_g×(N_CB–1)＝(352+N_g)×N_CB–N_g(ii) a Wherein N is_g＝66，N_CBMay be equal to 2, 3 or 4.
