Systems, methods, and devices perform channel interference detection for wireless devices. Methods include receiving a signal at a wireless device, the signal including at least one data subcarrier and one or more guard subcarriers. Methods also include determining, using processing logic, that one or more guard subcarriers are available for adjacent channel interference (ACI) detection, measuring, using the processing logic, a power of each of the one or more guard subcarriers and a total power of the one or more guard subcarriers, and determining, using the processing logic, an ACI is present based, at least in part, on the measurements of the one or more guard subcarriers. Methods further include performing, using the processing logic, one or more deweighing operations based on one or more identified features of the ACI.

Systems, methods, and devices for channel interference detection in wireless devices

Core transmit suspension is provided in multiple core wireless devices, systems, and methods. A first wireless device may transmit a plurality of data packets by a first core and a second core of the first wireless device to a second wireless device at a data rate. A data packet may be transmitted by at least one of the first core or the second core. The first wireless device may receive a first core acknowledgement (ACK) of the data packet by the first core and a second core ACK of the data packet by the second core from the second wireless device. The first wireless device may determine that a function of a power metric of the first core ACK and a power metric of the second core ACK satisfies a threshold to produce a result. The first wireless device may suspend, while the data rate sustains, transmission of the plurality of data packets by a suspended core of the first core or the second core based on the result.
