Abstract: A cooperation MIMO transmitting or receiving method is disclosed. A master terminal calculates a first signal to interference plus noise ratio (SINR), which is SINR between the mater terminal and a base station or between the master terminal and another cluster, and the master terminal calculates a second SINR, which is SINR between a slave terminal and the master terminal. Here, the master terminal forms a cluster with the slave terminal when the second SINR is higher than the first SINR.

Abstract: Disclosed are a method and a terminal for a distributed access. The terminal maps data channels to be allocated in a plurality of data channels included in a frame and map scheduling priorities. In this case, the terminal determines positions of resources of a first message as a resource request message and a second message as a response message for the first message in the first channel.

Abstract: Disclosed is a technique for switching from a master node to a secondary node in a communication system. A method of a first communication node may comprise: adding the first communication node as a primary secondary cell (PSCell) to a second communication node through dual connectivity (DC); generating a first user plane path for smart dynamic switching (SDS) and a first instance for supporting the first user plane path according to a request from the second communication node; transmitting information on the first user plane path and the first instance to a terminal; receiving user data based on the first user plane path from the terminal as the first instance; and transmitting the user data to a core network using the first user plane path.
