Abstract:
The present application relates to a scheduling device and method of a mobile communication system. In the packet scheduling method, a base station performs packet scheduling for a terminal station in a mobile communication system, and a transport channel comprising an uplink shared channel (UL-SCH) and a physical channel comprising an uplink grant channel (UL-GCH) between the terminal and the base station are classified into a plurality of channels. In addition, in the packet scheduling method: a) the base station receives scheduling information from the terminal; b) the base station allocates an uplink resource for uplink traffic transmission for terminal based on the received scheduling information; and c) information for the allocated uplink resource is transmitted to the terminal through the UL-GCH of the physical channel.
Abstract:
A method of retransmitting a packet for low-power wireless sensor communications of a coordinator in a sensor network is provided. The method includes receiving packets from a plurality of sensor devices during a plurality of guaranteed time slots (GTSs) of a Contention Free Period (CFP) which are allocated to the respective sensor devices; checking whether there is an error in each of the received packets; generating one GTS Bulk ACK frame that contains pieces of ACK information to be transmitted to the respective sensor devices, according to the error check results; and transmitting the generated GTS Bulk ACK frame to the plurality of sensor devices.
Abstract:
A method for controlling radio resource allocation for a low power sensor communication service by a relay coordinator. The method may include configuring a frame that includes a Contention Access Period (CAP) offset and a Contention Free Period (CFP) offset of variable sizes, and an Relay Period (RP) that relays data between a Personal Area Network (PAN) coordinator and one or more lower hierarchical devices; and generating a beacon frame that includes information of the frame configuration, and transmitting the beacon frame to the one or more lower hierarchical devices; and transmitting data, which is received from the one or more lower hierarchical devices through the CFP, to the PAN coordinator through the RP, or transmitting data, which is received from the PAN coordinator through the RP, to lower hierarchical nodes through the CFP.
