Indication of resource conflict

A method, comprising:

• receiving a first sidelink control information, SCI, from a first device indicating a first reserved radio resource for transmission by the first device;
• receiving a second SCI from a second device indicating a second reserved radio resource for transmission by the second device, the second re-served radio resource overlapping at least partially with the first reserved radio resource;
• determining a first received signal strength associated with the received first SCI;
• determining a second received signal strength associated with the received second SCI;
• determining at least one of a first modulation and coding scheme, MCS, applied by the first device or a second MCS applied by the second device;
• determining, based on at least one of the first MCS or the second MCS, at least one threshold;
• and
• determining, based on the at least one threshold and the determined first and second received signal strengths, whether or not to transmit a resource conflict indication to at least one of the first device or the second device.

A non-transitory computer program product comprising program instructions which, when executed by an apparatus, cause the apparatus at least to:

• receive a first sidelink control information, SCI, from a first device indicating a first reserved radio resource for transmission by the first device;
• receive a second SCI from a second device indicating a second re-served radio resource for transmission by the second device, the second reserved radio resource overlapping at least partially with the first reserved radio resource;
• determine a first received signal strength associated with the received first SCI;
• determine a second received signal strength associated with the received second SCI;
• determine at least one of a first modulation and coding scheme, MCS, applied by the first device or a second MCS applied by the second device;
• determine, based on at least one of the first MCS or the second MCS, at least one threshold;
• and
• determine, based on the at least one threshold and the determined first and second received signal strengths, whether or not to transmit a resource conflict indication to at least one of the first device or the second device.
