Abstract: Embodiments of the present invention provide a method and an apparatus for sending a non-data frame. 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.

Abstract: The present invention discloses a method for transmitting data between a baseband processing unit BBU and a remote radio unit RRU, and a data transmission apparatus. The RRU selects partial data in received data, and sends the partial data to the BBU by using a common public interface CPRI; or the BBU performs only channel coding processing or only channel coding processing and constellation mapping processing on the data, and sends processed data to the RRU. Then the RRU performs constellation mapping processing, multiple-antenna multiple-input multiple-output MIMO coding processing, and orthogonal frequency division multiplexing OFDM symbol generation processing on the data, or the RRU performs MIMO coding processing and OFDM symbol generation processing on the data. That is, steps in which data redundancy is added are executed by the RRU.
