Abstract: Embodiments may relate to group addressed frame delivery over multi-link systems. Systems and methods are configured for identifying, by an access point (AP) multilink device (MLD) in a wireless network, a first sequence number space (SNS) that is to be used by the AP MLD to transmit data to a non-AP MLD over a first communications link and a second communications link, wherein frames with identical data that are transmitted over the first and second communications links will have an identical first SN based on the first SNS; identifying, by the MLD in the wireless network, the first SN based on the first SNS; and transmitting, by the AP MLD in the wireless network, a frame that includes the data to the non-AP MLD based on the first SN.

Abstract: An electronic device (such as an access point) is described. This electronic device transmits an orthogonal frequency division multiple access (OFDMA) frame to a recipient electronic device (such as a client or a station). The OFDMA frame includes multiple predefined resource units (RUs) allocated to the recipient electronic device in a set of predefined RUs having associated frequency bandwidths. Moreover, the multiple predefined RUs include two or more first predefined RUs having a first number of tones less than a predefined amount, or two or more second predefined RUs having a second number of tones greater than or equal to the predefined amount. For example, the predefined amount may include 242 tones. Note that the multiple predefined RUs may have the same or different numbers of tones. Moreover, the electronic may receive an acknowledgment or a block acknowledgment from the recipient electronic device.

Abstract: An electronic device that communicates frames is described. During operation, the electronic device may transmit the frames addressed to a recipient electronic device and associated with multiple links between the electronic device and the recipient electronic device. Then, the electronic device may receive block acknowledgments for at least a subset of the frames, where a given block acknowledgment is associated with the recipient electronic device and indicates received frames on a given link in the links. Moreover, the electronic device may control an amount of traffic conveyed on the links based at least in part on the block acknowledgments. Next, the electronic device may store a remainder of the frames based at least in part on the block acknowledgments, where the frames include the subset of the frames and the remainder of the frames. Note that the frames may have a common traffic identifier.

Abstract: Some embodiments enable secure time of flight (SToF) measurements for wireless communication packets that include secure ranging packets with zero padded random sequence waveforms, including at higher frequency bands (e.g., 60 GHz) and in non-line of sight (NLOS) scenarios. Some embodiments provide a flexible protocol to allow negotiation of one or more security parameters and/or SToF operation parameters. For example, some embodiments employ: phase tracking and signaling to support devices with phase noise constraints to mitigate phase noise at higher frequencies; determining a number of random sequences (RSs) used for SToF to support consistency checks and channel verification; additional rules supporting sub-phases of the SToF operation; and/or determining First Path (FP), Sub-Optimal, and/or Hybrid path AWV modes and the pre-conditioning usage of these modes.

Abstract: A wireless local area network (WLAN) station (STA) reports, with a medium access control (MAC) frame, a buffer status of an urgent traffic identifier (TID) to a second STA. In some embodiments, the second STA is also an access point (AP). The delay in reporting is reduced by providing a buffer status report for the urgent TID in a data frame being transmitted to carry data for a current TID. The buffer status report, in some embodiments, provides the value of the urgent TID. In some embodiments, the buffer status report provides an indication of the amount of data in a buffer corresponding to the urgent TID. In some embodiments, the buffer status report is based on an aggregated measure of more than one buffer with data awaiting transmission. The transmission of the MAC frame, in some embodiments, is unsolicited.

Abstract: This disclosure relates to methods for conducting multilink communications between a user equipment device (UE) and a wireless access point (AP) over a wireless local area network (WLAN). The UE establishes a connection with an access point through a WLAN, wherein the connection utilizes a plurality of links. The UE transmits an indication to the access point through a first link of the plurality of links, where the indication specifies one or more available links of the plurality of links that are available for the UE to receive downlink (DL) communications from the access point. The UE receives one or more DL communications from the access point through at least one of the one or more available links.

Abstract: During operation, an electronic device (e.g., an access point) may provide a multi-user (MU)-request-to-send (RTS) frame that communicates an RTS in a channel associated with the second electronic device and a second RTS in a second channel associated with a third electronic device. For example, the channel may include a primary channel and the second channel may include a secondary channel. Note that the third electronic device may include a SST station and the second electronic device may include a non-SST station. Then, the electronic device may receive an MU-clear-to-send (CTS) frame that includes a CTS in a third channel associated with the third electronic device. Moreover, the third channel may be equal to or a subset of the second channel, and/or the third channel may include a CTS reception channel associated with the electronic device.
