1. An apparatus operating in a wireless local area network (WLAN), comprising:
an antenna;
a transceiver;
a memory that stores instructions; and
a processing circuit coupled to the memory, the processing circuit operable to execute the instructions to:
measure a received signal quality from a first portion of a packet transmitted from a source;
receive a header of the packet indicating a Modulation and Coding Scheme (MCS) used to encode a payload of the packet;
determine, based on the MCS, a required signal quality for correctly decoding the payload;
compare the received signal quality with the required signal quality; and
in response to a determination that the received signal quality is lower than the required signal quality, cause the transceiver to transmit a signal that overlaps in time and in frequency with a second portion of the packet, wherein the second portion starts before a Medium Access Control (MAC) header that indicates whether the packet is inter-BSS or intra-BSS.
