Classification: CPC H | IPC H

Claim 6:
7. A User Equipment, UE, for a cellular communication system, the UE configured to:
transmit a Random Access, RA, preamble;
receive a Random Access Response, RAR, from a base station, BS, containing information indicative of an added time delay, TF, between reception of the RA preamble by the BS and transmission of the RAR by the BS, the information indicative of the TF between the reception of the RA preamble by the BS and the transmission of the RAR by the BS comprising a value that corresponds to the TF, and the RAR further comprising a timing advance, TA, value indicative of a radio signal propagation delay between the UE and the BS;
determine a reference time, TR, value indicative of a time between transmitting the RA preamble and receiving the RAR;
determine a value, TERR, that is an absolute value of a difference between the TR value and a sum of the TA value and the TF value; and
determine that the RAR is not intended for the UE in response to determining that the TERR is greater than a predetermined threshold, TTHRESHOLD.
