Scheduling method for machine-to-machine communication

摘要

One embodiment of the present invention provides a scheduling method for machine-to-machine (M2M) communication. The method comprises the steps of: receiving a connection request message from each of a plurality of machines; grouping the plurality of machines into one or more groups; transmitting information on the group to which each machine belongs, to the machine; transmitting information on the machines belonging to each group, and control information including information on a time interval allocated to each group, to machines belonging to each group; and communicating with machines belonging to each group in a time interval allocated to each group.

1. A method of scheduling M2M (machine-to-machine) communication, the method comprising:
receiving, by an access point, an association request message from each of a plurality of devices; grouping, by the access point, the plurality of devices into one or more groups; transmitting, by the access point to the plurality of devices, first control information including information indicating devices belonging to each group and information indicating a time interval assigned to each group; transmitting, by the access point to devices belonging to a specific group, second control information including scheduling information of a time interval assigned to the specific group, the scheduling information indicating an uplink or downlink transmission time for each device belonging to the specific group within the time interval assigned to the specific group; and communicating, by the access point with the devices belonging to the specific group, at the time interval assigned to the specific group using the transmitted scheduling information, wherein devices belonging to a same group have a same transmission period, a same reception period, and a same quality of service (QoS) requirement, wherein the first control information is periodically transmitted to the plurality of devices in all time intervals, and wherein the second control information is transmitted to the devices belonging to the specific group only at a start time of the time interval assigned to the specific group.
