Patent ID: 10893549

Abstract:
A method performed by a user equipment (UE) is described. The method includes performing a random access procedure in a first downlink frequency resource and/or a first uplink frequency resource; in the random access procedure, monitoring an NPDCCH in the first downlink frequency resource; detecting an NPDCCH in the first downlink frequency resource; transmitting, to an evolved Node B (eNB), a narrowband physical uplink shared channel (NPUSCH) on a second uplink frequency resource based on detection of the NPDCCH on the first downlink frequency resource, in a case that the NPDCCH contains an uplink (UL) grant for contention resolution; and receiving, from the evolved Node B (eNB), a narrowband physical downlink shared channel (NPDSCH) on a second downlink frequency resource based on detection of the NPDCCH on the first downlink frequency resource, in a case that the NPDCCH contains a downlink (DL) assignment for contention resolution.
