    Abstract: Provided are a method for machine type communication (MTC) user equipment (UE) to connect to an evolved Node-B (eNB) in a random access procedure, and an apparatus employing the method. The method for MTC UE to connect to an eNB includes receiving, at the MTC UE, system information or a handover command from the eNB, transmitting, at the MTC UE, a random access preamble to the eNB, receiving, at the MTC UE, a random access response message from the eNB, and transmitting, at the MTC UE, a connection request message or a handover confirm message including information about a dedicated bandwidth of the MTC UE to the eNB such that the MTC UE can be allocated the dedicated bandwidth. Using this method, an eNB is notified of a dedicated bandwidth of MTC UE, and thus can effectively utilize radio resources.

    Abstract translation: 提供了一种用于在随机接入过程中连接到演进型节点B（eNB）的机器类型通信（MTC）用户设备（UE）的方法，以及采用该方法的设备。 MTC UE连接到eNB的方法包括在MTC UE处接收来自eNB的系统信息或切换命令，在MTC UE处向eNB发送随机接入前导码，在MTC UE处接收， 来自eNB的随机接入响应消息，并且在MTC UE处向MTC发送包括关于MTC UE的专用带宽的信息的连接请求消息或切换确认消息，使得可以向MTC UE分配专用带宽 。 使用该方法，向eNB通知MTC UE的专用带宽，从而可以有效地利用无线资源。

    Abstract: A positioning method using images and radio waves may include: estimating a distance and an angle from the positioning reference node to a positioning target terminal; identifying an obstacle or reflective object in a vicinity of the positioning target terminal or on a path between the positioning target terminal and the positioning reference node by using image information on the positioning target terminal at a position estimated by the distance and the angle; estimating an incident angle or a reflection angle of a radio wave signal reflected by the reflective object identified based on the image information; and estimating a position of the positioning target terminal based on the reflection angle and the distance.

    Abstract: Disclosed are a frame transmission method using a selective beamforming and a communication apparatus to perform the frame transmission method. The communication apparatus may determine a beamforming matrix based on classification information in which a plurality of subcarriers used for communication is classified into a plurality of frequency units, may map a long training field (LTF) sequence to the beamforming matrix, and transmit a beamforming training (BF-T) frame including the mapped LTF sequence to a plurality of stations, may receive, from the plurality of stations having receiving the BF-T frame, feedback information generated based on a reception strength of the BF-T frame, and may allocate frequency units to data frames to be transmitted to the plurality of stations based on the feedback information, and transmit the data frames using the allocated frequency units. The reception strength of the BF-T frame may be determined at each station for each frequency unit.
