Method for transmitting and receiving inter-UE coordination information in a wireless communication system and apparatus therefor

A first user equipment (UE) comprising:

• one or more transceivers;
• one or more processors configured to control the one or more transceivers;
• and
• one or more memories operably connected to the one or more processors,
• wherein the one or more memories are configured to store instructions performing operations based on being executed by the one or more processors,
• wherein the operations comprise:
• determining preferred resources or non-preferred resources related to transmission of a second UE;
• and
• transmitting, to the second UE, Inter-UE Coordination Information which includes information representing a set of the preferred resources or a set of the non-preferred resources,
• wherein the preferred resources or the non-preferred resources are determined based on a first resource pool, and
• wherein a resource pool used for the transmission of the Inter-UE Coordination Information is same as the first resource pool in which the set of the preferred resources or the set of the non-preferred resources is located,
• wherein, in case the set of the non-preferred resources is based on Inter-UE Coordination Scheme 1, a first resource location of the set of the non-preferred resources on a time domain is represented as a slot offset with respect to a reference slot for time resource indicator values (TRIV), and the first resource location is a predefined number of slots after the slot carrying the Inter-UE Coordination Information.

A device controlling a first user equipment (UE), the device comprising:

• one or more processors;
• and
• one or more memories operably connected to the one or more processors,
• wherein the one or more memories are configured to store instructions performing operations based on being executed by the one or more processors,
• wherein the operations comprise:
• determining preferred resources or non-preferred resources related to transmission of a second UE;
• and
• transmitting, to the second UE, Inter-UE Coordination Information which includes information representing a set of the preferred resources or a set of the non-preferred resources,
• wherein the preferred resources or the non-preferred resources are determined based on a first resource pool, and
• wherein a resource pool used for the transmission of the Inter-UE Coordination Information is same as the first resource pool in which the set of the preferred resources or the set of the non-preferred resources is located,
• wherein, in case the set of the non-preferred resources is based on Inter-UE Coordination Scheme 1, a first resource location of the set of the non-preferred resources on a time domain is represented as a slot offset with respect to a reference slot for time resource indicator values (TRIV), and the first resource location is a predefined number of slots after the slot carrying the Inter-UE Coordination Information.

One or more non-transitory computer readable mediums storing one or more instructions,

• wherein the one or more instructions configure a first user equipment (UE) to perform operations based on being executed by one or more processors,
• wherein the operations comprise:
• determining preferred resources or non-preferred resources related to transmission of a second UE;
• and
• transmitting, to the second UE, Inter-UE Coordination Information which includes information representing a set of the preferred resources or a set of the non-preferred resources,
• wherein the preferred resources or the non-preferred resources are determined based on a first resource pool, and
• wherein a resource pool used for the transmission of the Inter-UE Coordination Information is same as the first resource pool in which the set of the preferred resources or the set of the non-preferred resources is located,
• wherein, in case the set of the non-preferred resources is based on Inter-UE Coordination Scheme 1, a first resource location of the set of the non-preferred resources on a time domain is represented as a slot offset with respect to a reference slot for time resource indicator values (TRIV), and the first resource location is a predefined number of slots after the slot carrying the Inter-UE Coordination Information.

A method performed by a second user equipment (UE) comprising:

• receiving, from a first UE, Inter-UE Coordination Information which includes information representing a set of preferred resources or a set of non-preferred resources,
• wherein the preferred resources or the non-preferred resources related to transmission of the second UE are determined based on a first resource pool, and
• wherein the second UE receives the Inter-UE Coordination Information which is transmitted by using a resource pool same as the first resource pool in which the set of the preferred resources or the set of the non-preferred resources is located,
• wherein, in case the set of the non-preferred resources is based on Inter-UE Coordination Scheme 1, a first resource location of the set of the non-preferred resources on a time domain is represented as a slot offset with respect to a reference slot for time resource indicator values TRIV), and the first resource location is a predefined number of slots after the slot carrying the Inter-UE Coordination Information.

A second user equipment (UE) comprising:

• one or more transceivers;
• one or more processors configured to control the one or more transceivers;
• and
• one or more memories operably connected to the one or more processors,
• wherein the one or more memories are configured to store instructions performing operations based on being executed by the one or more processors,
• wherein the operations comprise:
• receiving, from a first UE, Inter-UE Coordination Information which includes information representing a set of preferred resources or a set of non-preferred resources,
• wherein the preferred resources or the non-preferred resources related to transmission of the second UE are determined based on a first resource pool, and
• wherein the second UE receives the Inter-UE Coordination Information which is transmitted by using a resource pool same as the first resource pool in which the set of the preferred resources or the set of the non-preferred resources is located,
• wherein, in case the set of the non-preferred resources is based on Inter-UE Coordination Scheme 1, a first resource location of the set of the non-preferred resources on a time domain is represented as a slot offset with respect to a reference slot for time resource indicator values (TRIV), and the first resource location is a predefined number of slots after the slot carrying the Inter-UE Coordination Information.
