  • Patent number: 11424823
    Abstract: 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.

  • Patent number: 10757703
    Abstract: The embodiments of the present application provide a resource scheduling method for same frequency networking in an LTE cluster system and a device thereof. The method includes: determining a first frequency domain resource in the LTE cluster system, wherein the first frequency domain resource is an accessible frequency domain resource available for group services and belongs to a frequency domain resource of the cluster system; dividing the first frequency domain resource into at least two frequency domain resource groups; and selecting one frequency domain resource group from the at least two frequency domain resource groups to perform group services when a newly-built group service exists, so as to implement same frequency networking resource scheduling. The embodiments of the present application can reduce or eliminate the same frequency interference in the group services.

  • Patent number: 10284455
    Abstract: 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.
