Abstract: Aspects of the present disclosure relate to a wireless device including one or more processors and a memory storing processor-readable instructions that, when executed by the one or more processors, causes the wireless device to perform operations. The operations include receiving a first message indicating a reuse transmission opportunity associated with a downlink transmission from a first device to a second device. The operations further include determining to participate in the reuse transmission opportunity based at least in part on the downlink transmission. The operations further include, during the reuse transmission opportunity, transmitting uplink communications to the first device concurrently with the downlink transmission from the first device to the second device in the same frequency channel.

Abstract: The present disclosure provides various aspects related to techniques for generating trigger frames, at an access point (AP), that reduce the overhead associated with triggering an uplink transmission from the wireless station (STA). Features of the present disclosure achieve this by, for example, utilizing a single per-user information field of the trigger to signal a plurality of random access resource units that may be allocated to the one or more STAs in the network. Such a technique is an improvement over the conventional system that require each random access resource unit to be signaled separately in a separate per-user information field (thus increasing the overhead). Additionally, aspects of the present disclosure allow the AP to effectively signal to the STA whether the one or more resources allocated to the at least one STA are a single user resource unit allocation or a multi-user resource unit allocation.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for enabling an immediate response. In this manner, issues can be avoided where data carried by the last symbol of a frame cannot be entirely decoded by a receiver within a deadline for generating an immediate response. One example method for wireless communications by a first apparatus generally includes determining at least one constraint for communicating with a second apparatus; generating a frame that solicits a response; and outputting the frame for transmission to the second apparatus, wherein at least a last symbol of the frame is transmitted in a manner determined by the constraint to allow the second apparatus to transmit the response within a determined period.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for communicating over a wireless communication network. A wireless communication device may be configured to generate and transmit a message according to a tone plan for transmission to multiple destination devices within one of a 240 or 320 MHz channel bandwidth. The message may include a short training field (STF) and a long training field (LTF). The STF may be used by a receiver to adjust an automatic gain control (AGC) function. The LTF may be used for channel estimation. In some implementations, the STF may have a data tone plan formed from a concatenated sequence of sub-STFs. A phase rotation applied to at least one of the sub-STFs of the concatenated sequence may reduce a peak-to-average-power ratio (PAPR) of the message as compared to a non- phase rotated concatenated sequence of sub-STFs.

Abstract: A method of wirelessly communicating includes generating, at a wireless device, a packet including a first preamble field. The method further includes generating a first repeated preamble field by multiplying the first preamble field by a first frequency-domain polarity sequence. The method further includes transmitting the packet from the wireless device. The packet includes the first preamble field and the first repeated preamble field.

Abstract: Methods and apparatuses are disclosed for communicating over a wireless communication network. In one aspect, an apparatus can include a memory that stores instructions, a processor, and a segment parser. The memory can be configured to store instructions. The processing system is configured to execute the instructions to generate a message according to a tone plan for transmission to one or more destination devices within one of a 240 or 320 MHz total channel bandwidth. The processing system is further configured to provide the message for transmission over the 240 or 320 MHz total channel bandwidth, where the message is encoded for transmission by at least one of a binary convolutional coded (BCC) interleaver or a low density parity check (LDDC) tone mapper. The segment parser is configured to segment the total channel bandwidth into a plurality of segments of equal or unequal sub-band bandwidths or number of data tones.

Abstract: Methods, systems, and devices for wireless communications are described. An access point (AP) may identify receiving wireless devices for which to send a wake-up radio (WUR) frame. The AP may obtain a basic service set identifier (BSSID) for the AP that is associated with (or intends to be associated with) the receiving wireless devices, the BSSID being known by the receiving wireless devices. The AP may perform a hashing function to the BSSID to obtain a hashed BSSID. The AP may use a first portion of the hashed BSSID as a first identifier. The AP may generate the WUR frame for transmission with an address identifier field that includes either the first identifier or a second identifier. The second identifier nay be based at least in part on the first identifier. The AP may transmit the WUR frame to the receiving wireless devices.

Abstract: Method and systems are disclosed for qualifying a wireless device as frequency hopping device. In some aspects, an access point (AP) may determine a frequency hopping pattern for the wireless device, and then allocate a sequence of unique resource units to the wireless device based on the frequency hopping pattern. Each of the unique resource units include a different set of frequency subcarriers. The AP may receive a series of uplink orthogonal frequency-division multiple access (OFDMA) transmissions from the wireless device on the allocated sequence of unique resource units.
