A data frame, a data transmitting method and a data transmitting device are provided. The data frame includes a set number of transmission time intervals each including at least two reference signal channels for transmitting pilot signals. A first transmission time interval of the set number of transmission time intervals further includes a control channel, a primary synchronization signal channel, a secondary synchronization signal channel, a broadcast channel, a shared channel and a guard time interval. Each transmission time interval other than the first transmission time interval further includes a control channel, a discovery signal channel, a shared channel and a guard time interval. A second slot of a last transmission time interval further includes a set number of access signal channels.

Data frame, data sending method and device

A method and an apparatus for time slot multiplexing, and a communication device. At least one multiplexing node group in a subnet of a TDMA communication system may be determined according to a connection relationship among all nodes in the subnet, where a shortest communication link between every two nodes in each multiplexing node group includes at least the preset quantity of nodes, the preset quantity of nodes includes the two nodes, and the preset quantity is no less than 4. For each multiplexing node group, a multiplexing time slot allocated to the multiplexing node group is determined, and each node in the multiplexing node group is controlled to transmit data in the multiplexing time slot. The time slots can be shared by the nodes in the multiplexing node group, and therefore multiple nodes can transmit data in the multiplexing time slot.
