Abstract
A method and device for uplink orthogonal frequency division multiple access random access, the method including receiving, by a station (STA), a first trigger frame sent by an access point AP, the STA supporting n resource units RUs, where n>1 and is an integer, the first trigger frame including information used to determine a number k of random access resource units (RA-RUs) allocated by the AP, where k is an integer >0, and setting, by the STA, in response to the STA determining that a first parameter is greater than or equal to a value of an orthogonal frequency division multiple access (OFDMA) random access backoff (OBO) counter, the value of the OBO counter to 0, and randomly selecting, by the STA, i RA-RUs from the k RA-RUs to send uplink data, where i≤n, and where the first parameter is associated with k.
