Abstract: A wireless device (14, 400) or a radio network node (12, 700) is configured to communicate in a wireless communication network (10). The wireless device (14, 400) or radio node in this regard transmits or receives a signal on an Narrowband Internet-of-Things, NB-IoT, carrier (16). The NB-IoT carrier (16) is within a bandwidth of a New Radio, NR, carrier (22), has a frequency center (24) whose position satisfies a requirement on that position relative to a channel raster (26), and has two or more subcarriers which each align in frequency with a respective subcarrier of the NR carrier (22).

Abstract: A network device transmits or receives using an LTE-M carrier with guard bands within the bandwidth of an NR carrier, wherein the subcarriers in the LTE-M carrier maximally align with subcarriers in NR. The center of the LTE-M carrier is located within the NR bandwidth such that: 1) a minimum number of NR resource blocks are occupied by any part of the LTE-M carrier and the guard bands at each end, given a predetermined bandwidth for each of the guard bands; and/or 2) given a predetermined number of NR resource blocks that can be occupied by any part of the LTE-M carrier and the guard bands at each end, a minimum guard band bandwidth from each end of the LTE-M carrier to the respective immediately adjacent NR resource block not occupied by any of part of the LTE-M carrier and the guard bands is maximized.

Abstract: In one aspect, a method for communicating in a wireless communication network includes transmitting or receiving (402) using an LTE-M carrier within the bandwidth of an NR carrier such that the LTE-M carrier overlaps at least a portion of NR guard band. The transmitting or receiving may be subject to aligning subcarriers in LTE-M and NR on the same grid and subject to raster placement. The LTE-M carrier may be positioned within the NR carrier so as to minimize the number of NR resource blocks occupied by the LTE-M carrier.
