An apparatus of a station (STA) is disclosed that includes processing circuitry configured to decode a basic service set (BSS) operating channels field and a primary channel field from an access point (AP) or personal basic service set control point (PCP), wherein the BSS operating channels field is a bitmap that indicates which 2.16 GHz channels of a plurality of 2.16 GHz channels are permitted to be used for transmissions in the BSS, and wherein the primary channel field indicates a 2.16 GHz channel of the plurality of 2.16 GHz channels that is a primary channel of the BSS. The processing circuitry may be further configured to determine the primary channel, a secondary channel, a secondary1 channel, and a secondary2 channel based on the BSS operating channels field and the primary channel field.

Abstract: This disclosure describes methods, apparatus, and systems related to a channel estimation field (CEF) for various standards, for example, the 802.11ay standard, for single carrier (SC) MIMO channel estimation. In one embodiment, the CEF can use Golay complementary sequences. In another embodiment, the Golay complementary sequences can be defined similar to Golay complementary sequences definitions that can be found in various legacy standards, for example, the legacy 802.11ad standard. Various embodiments of the disclosure can allow channel estimation in the time domain and/or frequency domain, having small or negligible inter-stream interference. Various embodiments of the disclosure can enable an extendable structure for various M×N MIMO configurations, where M and N are positive integers.
