Communication system, base station device and communication terminal device

Abstract

A communication system of the present disclosure includes a user equipment and a base station, in which a protocol stack between the user equipment and the base station includes PDCP, RLC, MAC and PHY. The base station includes a first node and one or more second nodes, the first node terminates the PDCP, each of the second nodes terminates the RLC, the MAC and the PHY. The base station is configured to perform radio communication with the user equipment that terminates the PDCP, the RLC, the MAC and the PHY.

1 . A communication system comprising a user equipment and a base station, in which a protocol stack between the user equipment and the base station includes PDCP, RLC, MAC and PHY, wherein
 the base station includes a first node and one or more second nodes,
 the first node terminates the PDCP, 
 each of the second nodes terminates the RLC, the MAC and the PHY, 
   
       and
 the base station is configured to perform radio communication with the user equipment that terminates the PDCP, the RLC, the MAC and the PHY. 
 
     
     
         2 . A base station used in a communication system comprising the base station and a user equipment, the base station comprising:
 a first node; and   one or more second nodes,   
       wherein a protocol stack between the user equipment and the base station includes PDCP, RLC, MAC and PHY, 
       the first node terminates the PDCP, 
       each of the second nodes terminates the RLC, the MAC and the PHY, and 
       the base station performs radio communication with the user equipment that terminates the PDCP, the RLC, the MAC and the PHY. 
     
     
         3 . A user equipment used in a communication system comprising a base station and the user equipment, wherein
 a protocol stack between the user equipment and the base station includes PDCP, RLC, MAC and PHY,   the user equipment terminates the PDCP, the RLC, the MAC and the PHY, and   the user equipment performs radio communication with the base station including a first node which terminates the PDCP, and one or more second nodes each of which terminates the RLC, the MAC and the PHY.
