Abstract: This disclosure describes methods, apparatus, and systems related to a modulation and coding scheme (MCS) system. The device may determine a wireless communications channel with a first device in accordance with a wireless communications standard. The device may generate a header in accordance with a communication standard, the header including, at least in part, a modulation and coding scheme (MCS) index value. The device may determine a code rate associated with the MCS index value based at least in part on the wireless communications channel. The device may cause to send the header to the first device over the wireless communications channel based at least in part on the MCS index value.

Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating a Physical Layer Protocol Data Unit (PPDU). For example, an Enhanced Directional Multi-Gigabit (DMG) (EDMG) station (STA) may be configured to encode a Physical Layer (PHY) Service Data Unit (PSDU) of at least one user in an EDMG PHY Protocol Data Unit (PPDU) according to an EDMG Low-Density Parity-Check (LDPC) encoding scheme, which is based at least on a count of one or more spatial streams for transmission to the user; and transmit the EDMG PPDU in a transmission over a channel bandwidth in a frequency band above 45 Gigahertz (GHz).

Abstract: This disclosure describes the generation and implementation of Golay sequences and Golay Sequence Sets (GSSs) for channel estimation in wireless networks. In one embodiment, this disclosure describes an extension of the Golay sequences Ga and Gb defined in various legacy standards to GSSs. In various embodiments, the disclosed GSSs can include a number of Golay complementary pairs (e.g., Ga and Gb). In one embodiment, the disclosed Golay complementary pairs can meet various predetermined design rules and can be used to define enhanced directional multi-gigabit (EDMG) short training field (STF) and/or channel estimation field (CEF) fields for multiple-input and multiple-output (MIMO) transmission.
