1. A method comprising:
receiving, by a first access point (AP), cooperation configuration information from a second AP, wherein the cooperation configuration information indicates basic coordination information of the second AP;
sending, by the first AP, in parallel with the second AP, using a frame format for a multi-user (MU) physical layer protocol data unit (PPDU), and according to the cooperation configuration information, first information to at least one first cooperation station (STA) associated with the first AP and at least one second cooperation STA associated with the second AP; and
transmitting, by the first AP by using a first quantity of first spatial streams allocated by the first AP, downlink data to the at least one first cooperation STA, wherein a sum of the first quantity of first spatial streams and a second quantity of second spatial streams from the second AP to the at least one second cooperation STA does not exceed a smallest value of upper limits of quantities of received spatial streams of a total of cooperation STAs associated with the first AP and the second AP.
