Wireless Communication via Combined Channel Training and Physical Layer Header Signaling

摘要

Embodiments herein relate to wireless communication using combined channel training and physical layer header (SIG) signaling. Devices that comply with the 802.11 ax or High Efficiency WLAN (HEW) standard may generate and transmit packets that include such combined information. The combined information may be beamformed to a receiver device via an OFDM signal, which may be decoded by the receiver device to obtain subsequent data included in the signal. For example, initial training symbols associated with channel training subcarriers in the signal may be detected and used to perform a rough estimate of the channel. The rough estimate may thereafter be refined using data symbols detected from adjacent data subcarriers using the channel training symbols. In this way, data subcarriers may also be used to determine a channel response along with channel training subcarriers. Channel training information may be transmitted with data, such as user-specific information, in a single symbol.

1. A device comprising:
at least one memory that stores computer-executable instructions; and at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to:
receive a first portion of a physical layer header (SIG), the first portion comprising common information that enables decoding a signal including channel training subcarriers interleaved with data subcarriers in one symbol duration;wherein the decoding comprises the at least one processor being further configured to execute the computer-executable instructions to determine, based at least in part on the common information, a portion of subsequent data in a second portion of the physical layer header (SIG) designated for the device.
