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： Techniques for resource block allocation in a multi-user MIMO High Efficiency WLAN system are provided. Specifically, teachings that when taken alone or together, provide a device or a group of devices with an improved resource allocation for the reduction of usable tone waste, are presented. The present disclosure includes a system that provides a user with a technique allocating data tones prior to the encapsulation unit or overhead tones on a resource block unit. Further, the total allocated bandwidth can be reduced prior resource allocation to overcome modulation and coding scheme downgrading caused by severe puncturing. Alternatively, only band edge basic resource blocks are reduced to account for overhead tones which largely reside on band edges.

摘要： 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.
