Abstract

A radio communication node ( 100 B) configures a number of first symbols to be used for dynamically adjusting transmission timing when performing uplink transmission in a first radio link connected to the upper node, and notifies the upper node thereof.

Claims (10)

1 . A radio communication node comprising:

a processor that configures a number of guard symbols respectively in a first adjustment method of adjusting transmission timing of a downlink between an upper node and the radio communication node, and a second adjustment method of adjusting transmission timing or reception timing of an uplink therebetween in addition to the transmission timing of the downlink; and

a transmitter that notifies the upper node or a lower node of the number of the guard symbols, which has been configured,

wherein the processor configures the number of the guard symbols in the first adjustment method and the number of guard symbols in the second adjustment method to be different number from each other.

2 . The radio communication node according to claim 1 , wherein the processor configures the number of the guard symbols in transition between a first function of connecting with the upper node, and a second function of connecting with the lower node.

3 . The radio communication node according to claim 1 , wherein the transmitter notifies the numbers of the guard symbols using a control element of Medium Access Control (MAC).

4 . A radio communication method in a radio communication node, the method comprising:

configuring a number of guard symbols respectively in a first adjustment method of adjusting transmission timing of a downlink between an upper node and the radio communication node, and a second adjustment method of adjusting transmission timing or reception timing of an uplink therebetween in addition to the transmission timing of the downlink; and

notifying the upper node or a lower node of the number of the guard symbols, which has been configured,

wherein the number of the guard symbols in the first adjustment method and the number of guard symbols in the second adjustment method are configured to be different number from each other.
