摘要:
The invention relates to a method of receiving a signal corresponding to a multicarrier signal transmitted via at least one transmission channel, the method comprising an estimation step (11) of estimating said channel and delivering overall information about said channel in the frequency domain, referred to as a “frequency response” and comprising frequency samples. According to the invention, such a method also comprises: a sharing step (12) of sharing said frequency samples in at least two frequency sample vectors; a transform step (13) of transforming said frequency sample vectors from the frequency domain to a transform domain and delivering, for at least one frequency sample vector, a partial response of said channel in said transform domain; and a feedback step (14) of transmitting a return signal back to said transmitter, the return signal conveying samples extracted from said partial responses and representative of said channel in said transform domain.
摘要:
A method for transmitting data packets in a communication network using a plurality of radio frequency channels, at least two of the radio frequency channels being concatenated to form a concatenated channel. The method includes: acquiring and reserving at least one of the channels from the concatenated channel, thus reserving a first frequency band for transmitting data packets to a first target device; acquiring and reserving channels from the concatenated channel that were unreserved during the first step of acquisition and reservation, thus reserving a second frequency band for transmitting data packets to a second target device; generating a preamble specific to a selected data packet, which includes a simultaneous transmission indicator on the first and second frequency bands; and simultaneously transmitting the data packets on the first and second frequency bands, from the selected packet and the specific preamble, before the selected packet on the second frequency band.

A method of transmitting a multi-carrier signal by a transmitter using at least two transmit antennas to at least one receiver using at least one receive antenna, the method comprising an obtaining step of obtaining at least one estimate of at least one transmission downlink channel. According to the invention, such a method comprises a transmission stage performing at least one iteration of the following steps, for at least one downlink channel: transmitting payload data over said downlink channel, while taking account of said downlink channel estimate; and updating said downlink channel estimate, while taking account of acknowledgment information acknowledging reception of said payload data and transmitted by the receiver associated with said downlink channel.

Methods, apparatuses, and computer readable media for crosslink management frames for a non-collocated access point (AP) multi-link device (MLD), the apparatus comprises processing circuitry configured to: encode an individually addressed management frame, the management frame comprising link information, the link information indicating a first link of the non-collocated AP MLD for which the management frame is intended, and configure an access point (AP) of the non-collocated AP MLD to transmit the management frame on the second link of the non-collocated AP MLD. Additionally, a non-AP MLD includes processing circuitry configured to: refrain from transmitting a second individually addressed management frame over a setup link while a third individually addressed management frame is being transmitted by a station (STA) affiliated with the non-AP MLD or the third individually addressed management frame has not successfully completed, failed due to a retry limit, or was discarded by a media access control (MAC) layer.

Methods, apparatuses, and computer readable media for advertising restricted target wakeup time (TWT) service periods (SP). Apparatuses of a station (STA) are disclosed, where the apparatuses comprise processing circuitry configured to: encode a beacon frame, the beacon frame comprising a target wake time (TWT) element, the TWT element indicating a restricted TWT service period (SP) of an overlapping basic service set (OBSS), the TWT element comprising a field indicating the TWT element is for the OBSS and configure the AP to transmit the beacon frame. The processing circuitry may be further configured to: refrain from transmitting during the TWT SP of the OBSS or end a transmission opportunities (TxOP) before the start of the TWT SP of the OBSS.

Methods, apparatuses, and computer readable media for ultra-low latency out-of-band radios are disclosed. Apparatuses of a station (STA) are disclosed, where the apparatuses comprise processing circuitry configured to associate with an access point (AP) on a first channel using a first transmit power, encode a physical (PHY) protocol data unit (PPDU) for transmission on a second channel, and configure the STA to transmit the PPDU on the second channel with a second transmit power, wherein a bandwidth of the first channel is less than the bandwidth of the second channel and wherein the first transmit power is greater than the second transmit power. The second channel may be punctured based on overlapping basic service sets (BSS) (OBSSs) signal strengths. The use of the second channel is restricted for communications related to low-latency applications. The transmit power on the second channel is reduced to lower the interference with OBSSs.

This disclosure describes systems, methods, and devices related to multi-link device (MLD) device resetup and transition. A device may perform an initial association with a first transition peer. The device may initiate a fast multi-link device (MLD) transition from the first transition peer to a second transition peer, wherein the MLD is configured to use authentication keys, and wherein at least one of the first transition peer or the second transition peer it is an access point (AP) MLD having a plurality of links associated with a plurality of APs within the AP MLD. The device may include an MLD link identification (ID) within a fast basic service set transition element (FTE) of a reassociation request or reassociation response frame, wherein the MLD link ID identifies an individual link of the plurality of links. The device may perform a second association with the second transition peer.
摘要:
A non-AP STA of a multi-link device (STA MLD) may be configured to encode a multi-link (ML) probe request frame for transmission to an access point STA (AP) of an AP MLD comprising a plurality of affiliated APs. When the probe request frame is sent outside the context of active scanning, to discover an AP of the AP MLD the ML probe request frame may be encoded to have an Address 1 field set to a broadcast address and an Address 3 field set to a BSSID of the AP, or encoded to have the Address 1 field set to a basic service set identity (BSSID) of the AP's BS. The non-AP STA may refrain from transmitting the ML probe request frame to the AP of the AP MLD in a corresponding link when another non-AP STA of the AP MLD has already received a ML probe response that included complete information from any one of the APs of the AP MLD in any link.
摘要:
Embodiments of an access point (AP) station (STA) configured for operating in a next-generation (NG) wireless local area network (WLAN) (i.e., EHT) are generally described herein. In some embodiments, a comb resource unit (RU) structure may be used to distribute tones of an RU across a wider bandwidth for narrow RU power spectral density (PSD) boosting for longer-range transmission in EHT to meet ETSI and/or FCC limitations.
