摘要： A plug-and-play radio base station autonomously establishes X2 logical interfaces and S1 logical interfaces with existing base stations and upper nodes. A new radio base station which is installed in a network advertises an IP address of the new radio base station over a transport network. An existing radio base station or an upper node which receives the IP address detects the number of hops from the new radio base station to the existing radio base station or the upper node. An initial logical interface with the new radio base station is established when the detected number of hops is below a predetermined threshold.

摘要： In a retransmission request transmitting method, an RLC sublayer of a receiving-side apparatus determines whether or not an RLC-PDU-data (or an RLC-data-Sub-PDU) not received yet is under retransmission control processing in a MAC sublayer; and generates and transmits a STATUS-PDU (NACK) including only a RLC-data-PDU which has neither been received yet nor is under the retransmission control processing in the MAC sublayer, on the basis of the determination result, at a timing when the STATUS-PDU is generated.
