Apparatuses and methods for resource selection in sidelink communications

A user equipment (UE) for sidelink communications, the UE comprising:

• a memory storing an instruction;
• and
• a processor configured to execute the instruction stored in the memory to:
• collect at least one of sidelink sensing information or resource reservation information of a first sidelink communication;
• collect at least one of sidelink sensing information or resource reservation information of a second sidelink communication, wherein subcarrier spacing (SCS) used in the first sidelink communication is greater than SCS used in the second sidelink communication;
• determine one or more candidate resources based on at least one of:
• the sidelink sensing information of the first sidelink communication, the resource reservation information of the first sidelink communication, the sidelink sensing information of the second sidelink communication, or the resource reservation information of the second sidelink communication;
• select one or more resources among the one or more candidate resources;
• and
• transmit, using the one or more selected resources, one or more packets,
• wherein determining the one or more candidate resources further comprises:
• excluding one or more resources from a set of resources based on:
• one or more resource reservations of the first sidelink communication having one or more corresponding sidelink reference signal received powers (SL-RSRPs) above a first threshold and one or more resource reservations of the second sidelink communication having one or more corresponding SL-RSRPs above a second threshold different from the first threshold.

A non-transitory computer-readable medium storing instructions that are executable by one or more processors of a user equipment (UE), to perform a method for resource selection and packet transmission in sidelink communications, the method comprising:

• collecting at least one of sidelink sensing information or resource reservation information of a first sidelink communication;
• collecting at least one of sidelink sensing information or resource reservation information of a second sidelink communication, wherein subcarrier spacing (SCS) used in the first sidelink communication is greater than SCS used in the second sidelink communication;
• determining one or more candidate resources based on at least one of:
• the sidelink sensing information of the first sidelink communication, the resource reservation information of the first sidelink communication, the sidelink sensing information of the second sidelink communication, or the resource reservation information of the second sidelink communication;
• selecting one or more resources among the one or more candidate resources;
• and
• transmitting, using the one or more selected resources, one or more packets,
• wherein determining the one or more candidate resources further comprises:
• excluding one or more resources from a set of resources based on:
• one or more resource reservations of the first sidelink communication having one or more corresponding sidelink reference signal received powers (SL-RSRPs) above a first threshold and one or more resource reservations of the second sidelink communication having one or more corresponding SL-RSRPs above a second threshold different from the first threshold.
