Flexible Indication for Start Position of Data Channel

A method in a node of a wireless communication network of controlling radio transmission in a wireless communication network, the method comprising:

• managing sending of downlink control information to a user equipment, the downlink control information controlling reception by the user equipment of a data channel which is based on modulation using subcarriers from a first frequency subband and a second frequency subband, and the downlink control information indicating, for the first frequency subband, a first start position for transmission of the data channel, and, for a second frequency subband, a second start position for transmission of the data channel, and
• based on the first start position and the second start position, controlling transmission of data on the data channel.

A method in a user equipment of controlling radio transmission in a wireless communication network, the method comprising:

• receiving downlink control information from the wireless communication network, the downlink control information controlling reception by the user equipment of a data channel which is based on modulation using subcarriers from a first frequency subband and a second frequency subband, and the downlink control information indicating, for the first frequency subband, a first start position for transmission of the data channel and, for the second frequency subband, a second start position for transmission of the data channel, and
• based on the first start position and the second start position, controlling receiving of data on the data channel.

A node for a wireless communication network, the node comprising:

• one or more processors and a memory, the memory including program code executable by the one or more processors whereby the node is configured to:
• manage sending of downlink control information to a user equipment, the downlink control information controlling reception by the user equipment of a data channel based on modulation using subcarriers from a first frequency subband and a second frequency subband, and the downlink control information indicating, for the first frequency subband, a first start position for transmission of the data channel and, for the second frequency subband, a second start position for transmission of the data channel, and
• based on the first start position and the second start position, control transmission of data on the data channel.

A user equipment comprising:

• one or more processors and a memory, the memory including program code executable by the one or more processors whereby the user equipment is configured to:
• receive downlink control information from a wireless communication network, the control information controlling reception by the user equipment of a data channel which is based on modulation using subcarriers from a first frequency subband and a second frequency subband, and the downlink control information indicating, for the first frequency subband, a first start position for transmission of a data channel and, for the second frequency subband, a second start position for transmission of the data channel, and
• based on the first start position and the second start position, control receiving of data on the data channel.
