Abstract

Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

Claims (50)

1. A method in a radio network node, the method comprising:

receiving a message from a first user equipment (UE) according to one of a plurality of uplink access configurations, the one of the plurality of uplink access configurations corresponding to an uplink access configuration index previously transmitted to the first UE; and

subsequently transmitting, to the first UE, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission having a first subcarrier spacing and a second OFDM transmission having a second subcarrier spacing, differing from the first subcarrier spacing.

2. The method of claim 1 , wherein the method further comprises:

broadcasting system access information for accessing the wireless communications network; and,

transmitting additional system information in response to a request from the first UE.
