Dynamic selection of multicarrier mode based on QoS parameters

A method in a transceiver configured to transmit and receive wireless transmissions, the method comprising:

• in a first time interval, modulating and transmitting data on a first portion of a frequency band, using a first multicarrier modulation mode having a first subcarrier spacing;
• and
• in a second time interval, modulating and transmitting data on a second portion of the frequency band, using a second multicarrier modulation mode having a second subcarrier spacing;
• wherein the first subcarrier spacing differs from the second subcarrier spacing;
• wherein the transceiver is comprised in a radio base station and wherein the method further comprises receiving, from a user equipment, an indication of said user equipment's capabilities with respect to multicarrier modulation modes.

A wireless transmitter, comprising:

• a transceiver circuit configured to transmit and receive wireless transmissions according to multicarrier modulation schemes;
• and
• a processing circuit operatively connected to the transceiver circuit and configured to control the transceiver circuit to:
• in a first time interval, modulate and transmit data on a first portion of a frequency band, using a first multicarrier modulation mode having a first subcarrier spacing;
• and
• in a second time interval, modulate and transmit data on a second portion of the frequency band, using a second multicarrier modulation mode having a second subcarrier spacing;
• wherein the first subcarrier spacing differs from the second subcarrier spacing;
• wherein the transceiver is configured for operation in a user equipment and wherein the processing circuit is further configured to control the transceiver to send, to a radio base station, an indication of the user equipment's capabilities with respect to multicarrier modulation modes.
