摘要： A method for performing network reentry by a Machine to Machine (M2M) device in a wireless communication system is provided. In the method, the M2M device receives information associated with an uplink resource for transmitting a ranging request message from a base station and transmits the ranging request message to the base station based on the received information associated with the uplink resource. The information associated with the uplink resource is masked with a random access identifier (RA-ID) and the RA-ID includes an indicator that indicates an M2M device dedicated ranging channel.

摘要： A method for performing, by a station (STA) apparatus, uplink (UL) multi-user (MU) transmission in a wireless communication system according to an embodiment of the present invention includes performing carrier sensing on a channel, receiving a trigger frame including information for UL MU transmission and a carrier sense indicator indicating whether a result of the carrier sensing is to be reflected from an access point (AP), and transmitting an UL MU frame through the channel based on the information for UL MU transmission. The UL MU frame is transmitted through the channel based on a result of the carrier sensing if the carrier sense indicator indicates the reflection of a result of the carrier sensing. The UL MU frame is transmitted through the channel regardless of a result of the carries sensing if the carrier sense indicator does not indicate the reflection of a result of the carrier sensing.
