Abstract: A method of managing a low-duty mode operation is provided by a small base station. The small base station determines a low-duty cycle pattern in which an available interval for data traffic transmission on active air interface and an unavailable interval for transmitting no data traffic are repeated, and provides a terminal with low-duty cycle pattern information. The low-duty cycle pattern information includes a length of the available interval and a start offset indicating a wireless frame at which the low-duty cycle pattern starts.

Abstract: Provided is a method of transmitting an anisochronous packet between devices in a time-sensitive wireless network. The method includes determining whether a whole packet to be transmitted is transmittable within a residual time of a contention period (CP), when the whole packet to be transmitted is not transmittable within the residual time of the CP, segmenting the packet to be transmitted into packet fragments with a length which is transmittable within the residual time of the CP, adding packet fragment information to the packet fragments, and transmitting one of the packet fragments within the residual time of the CP.

Abstract: Disclosed herein is a method and apparatus for synchronizing timeslots in a wireless LAN system. The timeslot synchronization method includes: setting, by a first node, a timeslot synchronization reference based on a time synchronization function (TSF) value, followed by transmitting information about a reference of synchronization to a second node; and setting, by the second node, a timeslot synchronization reference based on a TSF value corresponding to the reference of synchronization based on the information transmitted from the first node.

Abstract: An operation method of an access point (AP) and a terminal, in a wireless time sensitive network (WTSN), may comprise: receiving, by an AP, an uplink frame from a first terminal; generating compensation indication information for compensation to be performed in the first terminal according to channel information between the first terminal and the AP estimated based on the uplink frame; transmitting the compensation indication information to the first terminal through a downlink frame; and performing, by the first terminal, the compensation based on the compensation indication message transmitted through the downlink frame.

Abstract: Provided is a method for transmitting, by a transmitter, a first data having periodicity through a channel of an unlicensed band:
The transmitter adjusts at least one of transmission timing of the first data and clear channel assessment (CCA) timing for the channel to occupy the channel. The transmitter determines whether the channel may be occupied by performing a CCA on the channel at the CCA timing. The transmitter transmits the first data through the channel at the transmission timing of the first data, when it is determined that the channel may be occupied.

Abstract: An exemplary embodiment of the present invention provides a resource management method performed by a coordinator for controlling interference between cells. The coordinator receives a channel state of a second base station neighboring a first base station from the first base station. The coordinator partitions a resource based on the channel state. The coordinator allocates the partitioned resource to the first base station. In addition, the coordinator transmits a first message requesting resource management to be set to the first base station. Here, the first message includes information on the allocated resource.
