A method and apparatus of exchanging information on the number of layers which is supported commonly between the base station and the terminals in Multi-User Multiple Input Multiple Output (MU-MIMO) environment is provided for performance enhancement. The communication method of a terminal in a wireless communication system according to the present disclosure includes receiving a reference signal and information on a number of layers supportable simultaneously from a base station, measuring a channel state value based on the reference signal and the number of layers, determining whether the measured channel state value fulfills a minimum required channel state value, and transmitting, when the measured channel state value fulfills the minimum required channel state value, a value determined based on the measured channel state value to the base station.

Method and apparatus for exchanging information between base station and terminal

A method and a target node for preventing collisions between networks communicating based on a carrier sense multiple access/collision avoidance (CSMA/CA) scheme, are provided. The method includes synchronizing an object network with a neighboring network. The method further includes allocating, to the object network, a slot index based on a number of the networks, and a contention window (CW) size. The method further includes setting, for the object network, a back-off counter value based on the CW size. The method further includes reducing the back-off counter value based on a channel state of the object network, and the slot index. The method further includes transmitting data related to the neighboring network based on the back-off counter value.

Method and node for preventing collision between networks communicating based on CSMA/CA

Provided are low-power wireless communication apparatuses and a method thereof. A hub may receive a beacon signal from a neighboring hub that is within a predetermined area from the hub, and control an operation of a node served by the hub based on information received from the neighboring hub.
