Abstract: Implementations of the present disclosure relate to a method for decoding error correction. The method comprises detecting a failure of decoding a received frame. After the failure of decoding the received frame is detected, a type of the received frame is determined based on a probability that the received frame follows a prior frame of the received frame in a frame sequence. The method further comprises obtaining a template corresponding to the type of the received frame, and decoding the received frame based on the fixed values in the template. The template includes fixed values corresponding to the type of the received frame. With these implementations, correction ability of the decoding can be obviously improved with assistance of the constructed template.

Abstract: In embodiments of the present disclosure, a method is provided for managing a communication channel between a first communication unit and a second communication unit in an AP. At the first communication unit, a request is transmitted to the second communication unit for reserving a communication channel. Here, the second communication unit is associated with a Wi-Fi network that is different from a network type associated with the first communication unit, and the first and second communication units share a band of the communication channel. A response for reserving the communication channel is received from the second communication unit. In accordance with a determination that the response indicates the communication channel has been reserved for a time duration, data is transmitted at the first communication unit within the time duration on the communication channel. Therefore, conflicts between the first and second communication units in the AP may be reduced.
