Subframe multiplexing with different subcarrier spacings

A method, in a wireless device, for operating in a wireless communications network and operable for communicating with radio network equipment in the wireless communications network, the method comprising: receiving a first downlink signal comprising information indicating a plurality of uplink access configurations, each uplink access configuration including a random access configuration; receiving a second downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration among the indicated plurality of uplink access configurations, and transmitting to the wireless communication network a random access transmission in accordance with the random access configuration included in the identified uplink access configuration; characterized in that the method further comprises: receiving, in response, in a first downlink subframe, a first orthogonal frequency division multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second downlink subframe , a second OFDM transmission formatted according to a second numerology, the second numerology differs from the first numerology, in which the first numerology has a first subcarrier spacing and the second numerology has a second subcarrier spacing, the first subcarrier spacing differs from the second subcarrier spacing,
