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.

A method, a terminal, and a system for a cluster terminal to feedback downlink channel information are provided. In the method, a cluster terminal in an idle state configures a group call context and measures a current downlink channel in a preset period, after receiving a group call signaling sent by a base station. The cluster terminal sends an RRC connection request carrying a measurement result to the base station after determining that the measurement result meets a preset report triggering condition. The base station modifies an air interface resource configuration when determining that a preset condition for modifying the air interface resource configuration is met according to the measurement result and sends an instruction carrying the modified air interface resource configuration to the cluster terminal. The cluster terminal receives group call data according to the instruction after receiving the instruction.

A method, a base station and a system for managing resources belong to the field of communication technologies. In an embodiment of the present invention, the base station decodes the uplink data or the acknowledgement information sent by the user equipment according to the format of the periodic indication information comprised in the uplink data or the acknowledgement information, determines that the uplink data or the acknowledgement information sent by the user equipment comprises the periodic indication information when the decoding is successful, and then validates the periodic resources corresponding to the periodic indication information comprised in the uplink data or the acknowledgement information. The technical solution of the present invention overcomes the problem in the prior art that data is erroneously retransmitted since the base station and the user equipment asynchronously validate the periodic resources corresponding to the periodic indication information, thereby reducing interruption time delay.
