Abstract: Embodiments of the present application disclose a data transmission method, comprising: separately establishing, by a node, a connection to a macro base station and a small cell, where the node, the macro base station, and the small cell are located in a same access network, and the connection is an X2 connection or a user-defined logical connection; and scheduling, by the node, coordinated data, where the coordinated data is data cooperatively transmitted by the macro base station and the small cell for user equipment. In the present application, the node is additionally deployed in the access network, and the node schedules coordinated data in a macro-micro coordination process, therefore the delay of transmission between the macro base station and the small cell is shortened, and the macro-micro coordination performance is improved.

Abstract: Embodiments of the present invention discloses a method and a device for allocating a group identifier, which can allocate a non-conflict GID to a non-AP STA in an area covered by multiple BSS networks, so that the problem of GID conflict which is occurred when allocating the GID for the non-AP STA can be reduced. A method provided by the embodiment of the present invention includes: dividing all group identifiers (GIDs) into N parts according to number of the GIDs, and respectively allocating the N parts to N basic service set (BSS) networks, which communicate in a multi user-multiple input multiple output (MU-MIMO) mode, where the N BSS networks have a common area, N is a natural number which is bigger than 1.

Abstract: The present disclosure discloses a distributed antenna system. The DAS includes a signal source, a first signal generator, a first passive mixer, and a first antenna. The first signal generator is configured to: generate a first local-frequency signal, and send it to the first passive mixer by using a passive DAS line. The first passive mixer is configured to receive the first local-frequency signal, and a downlink radio frequency signal having a second radio frequency band. The first passive mixer is further configured to: perform frequency mixing processing on the received downlink radio frequency signal having the second radio frequency band by using the first local-frequency signal, to form a first downlink radio frequency signal having a first radio frequency band, and then send it to the first antenna. The first antenna is configured to transmit the received first downlink radio frequency signal having the first radio frequency band.

Abstract: This application relates to a scheduling method and a device. In the scheduling method, a base station sends, at a first moment, uplink grant (UL GRANT) information to a terminal that is to perform uplink data transmission; the base station sends, at a second moment, downlink data to a terminal that is determined by the base station and that is to perform downlink data transmission, where the second moment is a moment at which the terminal that is to perform uplink data transmission sends uplink data after receiving the uplink grant information at the first moment.
