    摘要： Short range wireless communication is provided. A first node included in a Wireless Body Area Network (WBAN) communicates with at least one neighboring second node. The first node transmits or receives data to or from at least one device node connected to the first node during a time division communication period, using a super-frame in which the time division communication period, a time division schedule advertisement message transmission period, and a Contention Access Period (CAP) are sequentially arranged. The first node broadcasts a time division schedule advertisement message of the first node to the at least one second node during the time division schedule advertisement message transmission period within the super-frame. Upon receiving a time division schedule advertisement message from the second node during the CAP within the super-frame, the first node adjusts a data transmission or reception time for the at least one device node connected to the first node using the received time division schedule advertisement message.

    摘要： Provided are an apparatus and method for transmitting data using an Adaptive Modulation and Coding (AMC) scheme in a mobile communication system with a Relay Station (RS). A relay indicator value is received indicating a strength of a downlink signal transmitted to a destination through a relay path including the RS and a direct indicator value indicating a strength of an downlink signal directly transmitted to the destination via a direct path without passing through the RS. Modulation and Coding Scheme (MCS) levels are determined using the relay and direct indicator values for both the relay and direct paths. Bandwidth efficiencies are found in correspondence with the MCS levels and are compared depending on whether the relay path or the direct path is used. A path resulting in a higher bandwidth efficiency is selected to generate a data frame having a structure corresponding to the selected path. The data frame is transmitted to the destination or the RS.
