The method for sending a non-data frame includes: determining an access category for which a transmission opportunity of a shared medium has been obtained, where the obtained transmission opportunity of the shared medium is obtained for the access category through contention according to an enhanced distributed channel access mechanism; and sending a non-data frame according to the access category for which the transmission opportunity of the shared medium has been obtained. In this way, different quality-of-service requirements of a non-data frame and a data frame are met while fairness is considered, thereby avoiding that a management and control message is not sent in time because a non-data frame and a data frame are transmitted according to a same access category. ## Claims ### Claim 1 A method for sending a non-data frame comprising: determining, by an apparatus, an access category for which a transmission opportunity of a shared medium has been obtained, wherein the transmission opportunity of the shared medium is obtained for the access category through contention among a plurality of access categories according to an enhanced distributed channel access mechanism; and sending the non-data frame according to the access category for which the transmission opportunity of the shared medium has been obtained. ### Claim 2 (depends on 1) The method according to claim 1, wherein the non-data frame is queued according to a priority. ### Claim 3 (depends on 2) The method according to claim 2, wherein the plurality of access categories comprise at least two of a background category, a best-effort category, a video category, and a voice category. ### Claim 4 (depends on 2) The method according to claim 2, wherein the access category comprises an access category of a relatively high priority. ### Claim 5 (depends on 2) The method according to claim 2, wherein the priority comprises at least one of a priority of a user, a non-data frame property, and message urgency. ### Claim 6 (depends on 5) The method according to claim 5, wherein the plurality of access categories comprise at least two of a background category, a best-effort category, a video category, and a voice category. ### Claim 7 (depends on 5) The method according to claim 5, wherein the access category comprises an access category of a relatively high priority. ### Claim 8 (depends on 1) The method according to claim 1, wherein the plurality of access categories comprise at least two of a background category, a best-effort category, a video category, and a voice category. ### Claim 9 (depends on 1) The method according to claim 1, wherein the access category comprises an access category of a relatively high priority. ### Claim 10 An apparatus for sending a non-data frame, comprising: a processor configured to determine an access category for which a transmission opportunity of a shared medium has been obtained, wherein the transmission opportunity of the shared medium is obtained for the access category through contention among a plurality of access categories according to an enhanced distributed channel access mechanism; and a transmitter configured to send the non-data frame according to the access category for which the transmission opportunity of the shared medium has been obtained. ### Claim 11 (depends on 10) The apparatus according to claim 10, wherein the plurality of access categories comprise at least two of a background category, a best-effort category, a video category, and a voice category. ### Claim 12 (depends on 10) The apparatus according to claim 10, wherein the access category comprises an access category of a relatively high priority. ### Claim 13 (depends on 10) The apparatus according to claim 10, wherein the non-data frame is queued according to a priority. ### Claim 14 (depends on 13) The apparatus according to claim 13, wherein the priority comprises at least one of a priority of a user, a non-data frame property, and message urgency. ### Claim 15 (depends on 14) The apparatus according to claim 14, wherein the plurality of access categories comprise at least two of a background category, a best-effort category, a video category, and a voice category. ### Claim 16 (depends on 14) The apparatus according to claim 14, wherein the access category comprises an access category of a relatively high priority. ### Claim 17 (depends on 13) The apparatus according to claim 13, wherein the plurality of access categories comprise at least two of a background category, a best-effort category, a video category, and a voice category. ### Claim 18 (depends on 13) The apparatus according to claim 13, wherein the access category comprises an access category of a relatively high priority.
