Abstract:
PROBLEM TO BE SOLVED: To improve the success rate of an RA (Random Access).SOLUTION: In a base station 10, a path timing detection part 121 is configured to, from a reception Msg3 received after an RA (Random Access) preamble is received in an RA procedure, detect a path timing of each Msg3 included in the reception Msg3, and a cancellation part 123 is configured to, on the basis of the detected path timing of each Msg3, cancel each Msg3 from the reception Msg3, and a demodulating/decoding part 117 demodulates data to be demodulated after the Msg3 of a UE#1 is cancelled from the reception Msg3 to obtain the Msg3 of a UE#2 included in the reception Msg3, and the demodulating/decoding part 117 is configured to demodulate the data to be demodulated after the Msg3 of the UE#1 is cancelled from the reception Msg3 on the basis of a desired PA timing among detected PA timings. The desired timing is the PA timing other than the PA timing corresponding to the path timing of the Msg3 of the UE#1 among the PA timings detected by a preamble detection part 107.SELECTED DRAWING: Figure 4
