    Abstract: An operation method of a first node belonging to an Xhaul network in a wireless backhaul system including the Xhaul network may comprise transmitting first resource allocation information to a second node and third nodes; receiving, from the second node, information of cross polarization interferences (XPIs) measured for wireless signals through wireless links generated based on the first resource allocation information; generating second resource allocation information indicating resources allocated to each of the second node and the third nodes based on the information of the XPIs; and transmitting the second resource allocation information to the second node and the third nodes, wherein the XPIs for the wireless signals are measured by the third nodes.

    Abstract: Disclosed are a random access method and a random access apparatus in a wireless communication system. An operation method of a terminal in a communication system, according to the present invention, comprises receiving system information including configuration information on a physical random access channel (PRACH) composed of a plurality of access slots from a first base station; selecting one access slot among the plurality of access slots based on the configuration information; and transmitting a random access preamble to the first base station through the one access slot. Therefore, the capacity of the random access channel can be increased without further occupation of radio resources.

    Abstract: A clustering wireless base station includes a group digital processor including a plurality of digital units (DU) and a plurality of remote radio frequency units (RRU) that are connected to the group digital processor through a transport network and that are installed in each service target area. In this case, each DU includes a decoder that decodes upward data that is received from the each DU, and each RRU includes an encoder that encodes downward data from the each DU.
