摘要： Embodiments of the disclosure provide auto-detection in wireless telecommunications. Certain embodiments provide or otherwise implement a specific sequence of bits and/or symbols for auto-detection. The specific sequence of bits can be embodied in or can include output codebits from an encoder in a communication device that can send a wireless transmission including the specific sequence. In one embodiment, the encoder can compute or otherwise generate cyclic redundancy checks (CRCs) or other types of validation checks at the communication device. The specific sequence can be determined using the payload of a packet frame. Both the manner in which the specific sequence is generated and the temporal order in which the specific sequence is received relative to other payload in the packet frame can provide specificity to the sequence.

摘要： This disclosure describes systems, methods, and devices related to an extreme high throughput (EHT) signaling structure. A device may establish a communication channel with one or more station devices (STAs). The device may generate an extreme high throughput signal field (EHT-SIG) of a header, wherein the EHT-SIG field comprises information associated with resource allocations (RUs). The device may generate a frame comprising the header. The device may assign a first RU to a first station device. The device may assign a second RU to the first station device, wherein the first RU or the second RU is an aggregation of a 26-tome RU and a neighboring RU. The device may cause to send the frame to the first station device.

摘要： This disclosure describes systems, and methods related to determining carrier frequency offset of a wireless communication channel based on a determined phase difference. In some embodiments, an access point is caused to receive one or more streams comprising one or more encoded long training field (LTF) symbols over the wireless communication channel from one or more user devices. The access point then determines a first phase of the wireless communication channel upon receipt of a first LTF symbol, and determines a second phase of the wireless communication channel upon receipt of a second LTF symbol. The access point next determines a phase difference between the first phase and the second phase. Based on the determined phase difference, the access point determines a carrier frequency offset of the wireless communication channel. Lastly, the access point modifies the wireless communication channel based at least in part on the determined CFO.
