Transmission In A Guard Band Of A RAT

A base station for configuring a radio node to transmit, within a guard band for a first radio access technology (RAT), a radio signal according to a second RAT, the base station comprising:

• processing circuitry;
• and
• memory containing instructions executable by the processing circuitry whereby the base station is configured to:
• determine, based on a channel bandwidth of the first RAT, one or more transmit parameters for transmission of the radio signal according to the second RAT, for transmission of the radio signal to comply with emission limits for the first RAT, wherein the one or more transmit parameters include a frequency position of the radio signal within the guard band of the first RAT;
• and
• configure the radio node with the one or more transmit parameters for transmitting the radio signal according to the second RAT within the guard band of the first RAT.

A user equipment for transmitting, within a guard band for a first radio access technology (RAT), a radio signal according to a second RAT, the user equipment comprising:

• processing circuitry;
• and
• memory containing instructions executable by the processing circuitry whereby the user equipment is configured to:
• determine, based on a channel bandwidth of the first RAT, one or more transmit parameters for transmission of the radio signal according to the second RAT, for transmission of the radio signal to comply with emission limits for the first RAT, wherein the one or more transmit parameters include a frequency position of the radio signal within the guard band of the first RAT;
• and
• transmit the radio signal with the one or more transmit parameters according to the second RAT within the guard band of the first RAT.
