Abstract: The application relates to link adaptation for extremely high throughput (EHT) systems. Various approaches are provided to enable transmission of link adaptation parameters for single-user multiple input multiple output (SU-MIMO), and multi-user multiple input multiple output MU-MIMO. In some embodiments, two control IDs in the A-control subfield are used, one for SU-MIMO and one for MU-MIMO. These can both be reserved control IDs, or a combination of a reserved control ID and control ID 2 normally used for HE link adaptation. In some embodiments, a single control ID in the A-control subfield is used. This can be a reserved control ID or control ID 2 normally used for HE link adaptation.

Abstract: A method, apparatus and system for transmitting control information in a header of a physical protocol data unit (PPDU), such as an IEEE 802.11 compliant PPDU. Embodiments include indicating control features in an EDMG PPDU for Wireless LAN communications. The method and system may include overloading at least one bit of a Scrambler Initialization Field in the PPDU header (e.g. the PHY header) to convey control information, as well as to be used to initialize the scrambler shift register. The same header bits are thus used for both purposes. Examples of control information include a primary channel, channel width or MIMO configuration to be used in further communication.

Abstract: A method of communication between a first node and a second node operating in a communications network. The method includes sending, by the first node, to the second node, a first transmission to configure a communication channel between the first node and the second node. The first transmission includes a first frame including a first capability indicator. The first capability indicator indicates a first MU-MIMO capability of a transmitter of the first node. The first multi-user (MU)-MIMO capability includes a first Modulation and Coding Scheme (MCS) processable by the first node or a first number of spatial streams (NSS) processable by the first node.

Abstract: Aspects of the disclosure provide for methods and systems for Sub-codebook based Trellis Coded Quantization for CSI Feedback. An aspect of the disclosure provides method executed by a receiver. The method includes receiving a signal from a transmitter, via a communication channel between the receiver and the transmitter. The method further includes estimating parameters associated with the channel based on the received signal. The method further includes obtaining phase information from the estimated parameters. The method further includes applying a trellis coded quantization (TCQ) scheme to the obtained phase information by mapping each sub-codebook index of a set of sub-codebook indices to output bits of each trellis branch making the distance between sub-codebooks maximally equal. The method further includes transmitting a channel state information (CSI) measurement feedback to the transmitter, the CSI measurement feedback based on the TCQ scheme and comprising one or more of: a beginning state, input bits to the TCQ scheme, and a sub-codebook index.

Abstract: Waveform-coding is applied to map successive on-off-keying (OOK) data bits onto successive multicarrier modulated symbols in time domain, wherein each multicarrier modulated symbol includes a set of sub-carriers in which alternating sub-carriers are set to non-zeros and zeros in frequency domain. The waveform coded multicarrier modulated symbols are up-converted to a carrier frequency to provide a data signal that is transmitted over a wireless channel.
