Various embodiments include an apparatus to be employed by an enhanced Node B (eNB), the apparatus comprising communication circuitry to receive, from a user equipment (UE), feedback information and control circuitry, coupled with the communication circuitry, to identify a codeword from a three-dimensional codebook based on the feedback information received from the UE, wherein the communication circuitry is further to precode data to be transmitted to the UE based on the codeword. An apparatus to be employed by a UE and additional methods are described.

Codebook for full-dimension multiple input multiple output communications

An extremely high-throughput (EHT) station (STA) is configured for transmission of a control response frame for rate selection. In response to a frame carried in an EHT PPDU soliciting a control response frame, the EHT STA may calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate, The EHT STA may also encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU, or encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU. A reduction in overhead may be achieved by using an HE SU PPDU or an EHT PPDU instead of a non-HT PPDU to carry a solicited control response frame.

EHT STA configured for transmission of a control response frame for rate selection

This disclosure describes systems, methods, and devices related to antenna configuration parameters. A device may determine one or more antennas having one or more phases. The device may determine a first delay associated with a first antenna of the one or more antennas. The device may determine a second delay associated with a second antenna of the one or more antennas. The device may cause to send a frame to a first station device using the first antenna, wherein the frame comprises a first indication of the delay associated with the first antenna and a second indication of the delay associated with the second antenna.

Antenna configuration parameters

For example, an apparatus may include a segment parser to parse scrambled data bits of a PPDU into a first plurality of data bits and a second plurality of data bits, the PPDU to be transmitted in an OFDM transmission over an aggregated bandwidth comprising a first channel in a first frequency band and a second channel in a second frequency band; a first baseband processing block to encode and modulate the first plurality of data bits according to a first OFDM MCS for transmission over the first channel in the first frequency band; and a second baseband block to encode and modulate the second plurality of data bits according to a second OFDM MCS for transmission over the second channel in the second frequency band.

Apparatus, system and method of transmitting a PPDU over a 320 megahertz channel bandwidth

The application provides a method, including: generating a Physical Layer (PHY) Protocol Data Unit (PPDU) comprising both information for one or more first-generation stations (R1 STAs) and information for one or more second-generation stations (R2 STAs); and transmitting the PPDU to the one or more R1 STAs and the one or more R2 STAs, wherein a preamble portion of the PPDU comprises Resource Unit (RU) allocation entries corresponding to the one or more R1 STAs and RU allocation entries corresponding to the one or more R2 STAs.

Method and apparatus used in WLAN networks

This disclosure describes systems, methods, and devices related to enhanced feedback for secure mode wireless communications. A device may send a first null data packet (NDP) to a second device, and identify a second NDP received from the second device. The device may identify a location measurement report (LMR) received from the second device, the LMR including a first channel response indicative of a first arrival time of the first NDP at the second device and a first phase shift associated with the first NDP. The device may generate a second channel response indicative of a second arrival time of the second NDP at the device and a second phase shift associated with the second NDP. The device may determine that the first channel response does not match the second channel response, and may identify an attempted attack.

Enhanced feedback for secure mode wireless communications

The disclosure provides some embodiments for securing long training field (LTF) sequence. A responding station (RSTA) configures a location management report (LMR) frame. The LMR frame is configured to include an LMR in respect of a previous measurement, and data to be used to generate a null data packet (NDP) for a current measurement that is to be performed following the previous measurement. The RSTA further encrypts the LMR frame using protected management frames (PMF) scheme, and transmits the encrypted LMR frame to an initiating station (ISTA) for generating an LTF sequence for the current measurement. In response to receiving an NDP announcement (NDPA) and an NDP for the current measurement from the ISTA, the RSTA generates an NDP for the current measurement based on the NDPA and the data using CCMP, and transmits the NDP to the ISTA.

Encryption of management frames for securing long training field sequence generation and scheme for transmitting sounding signal indications

An extremely high throughput (EHT) station (STA) configured for trigger based (TB) transmission may decode an trigger frame (TF) received from an access point (AP). The TF may include an assignment of resources comprising one or more 20 MHz channels. The EHT STA may determine which of the one or more assigned channels are available for transmission and which of the allocated channels are unavailable when the EHT STA is assigned more than one 20 MHz channel. The EHT STA may encode a EHT TB PPDU in response to the trigger frame. The EHT TB PPDU may be encoded to include an EHT preamble followed by a data field. The EHT preamble may be encoded to indicate channel availability. The EHT STA may generate signaling to cause the EHT STA to transmit the encoded EHT TB PPDU only on the assigned channels that have been determined to be available.

Trigger-based PPDU resource indication for EHT networks

For example, a Next Generation Vehicular (NGV) wireless communication station (STA) may be configured to generate an NGV Physical Layer (PHY) Protocol Data Unit (PPDU) including an NGV preamble, the NGV preamble comprising a non High-Throughput (non-HT) Short Training Field (L-STF), a non-HT Long Training Field (L-LTF) after the L-STF, a non-HT Signal (L-SIG) field after the L-LTF, a Repeated L-SIG (RL-SIG) field after the L-SIG field, and an NGV Signal (NGV-SIG) field after the RL-SIG field, the NGV-SIG field including a version field configured to identify a version of the NGV PPDU; and to transmit the NGV PPDU over an NGV channel in an NGV wireless communication frequency band; and a memory to store information processed by the processor.

Apparatus, system and method of communicating a physical layer (PHY) protocol data unit (PPDU) with version identifier

This disclosure describes systems, methods, and devices related to extreme high throughput (EHT) data scrambler. A device may determine an extreme high throughput (EHT) data field of a frame to be scrambled using an EHT data scrambler. The device may determine to initialize the EHT data scrambler using an initialization seed, wherein the initialization seed has a size greater than seven bits. The device may generate scrambled data using the initialization seed. The device may cause to send the frame comprising the scrambled data to a first station device.

This disclosure describes systems, methods, and devices related to secure location measurement sharing. A device may cause to send a first indication associated with a location of the device to a cloud server. The device may cause to send a second indication associated with a ranging information of an access point (AP), wherein the AP is connected to the cloud server. The device may identify an access token received from the cloud server, wherein the access token is associated with providing anonymized AP location information to the AP, and wherein the access token is associated with accessing channel allocation from a channel access database.

Secure location measurement sharing

Methods, apparatuses, and computer readable media for channel state information for multiple access points are disclosed. Channel station information (CSI) may be coordinated for multiple access points (APs) where one AP may act as a master AP with other AP acting as slave APs. The channel station information may be based on information from null data packets received by stations from multiple-APs, which may enable a multi-AP coordinated beamforming (CBF) to be determined based on the received first CSI reports. New frame formats are disclosed that include fields for including APs. Overlapping basic service set (OBSS) stations may respond to APs that are not within their BSS. Some embodiments relate to passive range finding in a multi-AP sounding where location configuration information (LCI) changes for one of the APs.

Channel state information for multiple access points

This disclosure describes systems, methods, and devices related to enhanced constellation shaping. A device may generate payload bits associated with a frame, wherein the payload bits comprise a first portion and a second portion. The device may send the first portion of the payload bits through a shaping encoder. The device may generate shaped bits from the shaping encoder. The device may determine a number of amplitude bits based on the shaped bits. The device may generate parity bits from the shaped bits and the second portion going through an low-density parity-check (LDPC) encoder. The device may select sign bits comprising the second portion and a first subset of the parity bits. The device may send the amplitude bits with the sign bits to a modulator before transmitting the frame to a first station device.

Peak rate enhancement for constellation shaping

This disclosure describes systems, methods, and devices related to fixed-to-fixed shaping encoding. A device may determine a mapping table associated with uniformly distributed bits into amplitudes with desired probabilities. The device may predict a number of output bits for an input block. The device may apply padding as needed based on the predicted number of output bits.

Constellation shaping with fixed-to-fixed shaping encoding

This disclosure describes systems, methods, and devices related to null data packet (NDP) frame format. A device may cause to send a null data packet announcement (NDPA) frame to a responding station device (RSTA). The device may cause to send a first sounding NDP frame comprising one or more fields formatted to support 2.4 gigahertz (GHz) and 5 GHz bands in a non-trigger-based ranging measurement with the RSTA. The device may identify after a passage of a short inter-frame space (SIFS) time a second NDP frame received from the RSTA. The device may identify a location measurement report frame from the RSTA.
