V2X resource map for semi-persistent scheduling with unicast/groupcast services

An apparatus, comprising:

• a memory;
• and
• one or more processors in communication with the memory, wherein the one or more processors are configured to:
• determine a resource map for use in scheduling semi-persistent resources for side-link communications with at least one wireless node, wherein the resource map request message includes a periodicity of the preferred resource blocks;
• generate instructions to transmit, to the at least one wireless node, a resource map request message indicating preferred resource blocks for use in the side-link communications, wherein the resource map request message includes a triggering threshold for triggering a report of downlink channel conditions, wherein a resource block is defined by a time and a frequency, and wherein the triggering threshold includes a threshold value and a period of time;
• receive, from the at least one wireless node, a confirmation message, wherein the confirmation message includes a report regarding a set of resource blocks of the preferred resource blocks indicated in the resource map request message;
• determine, based, at least in part, on the confirmation message, resource blocks to be used for the side-link communications with the at least one wireless node;
• and
• generate instructions to initiate the side-link communications with the at least one wireless node using the determined resource blocks.

A non-transitory computer readable memory medium storing program instructions executable by processing circuitry to cause a user equipment device (UE) to:

• determine a resource map for use in scheduling resources for side-link communications with at least one wireless node;
• generate instructions to transmit, to the at least one wireless node, a resource map request message indicating preferred resource blocks for use in the side-link communications, wherein a resource block is defined by a time and a frequency, wherein the resource map request message includes a triggering threshold for triggering a report of downlink channel conditions, and wherein the triggering threshold includes a threshold value and a period of time;
• receive, from the at least one wireless node, a confirmation message, wherein the confirmation message includes a report regarding a set of resource blocks of the preferred resource blocks indicated in the resource map request message, wherein the report regarding the set of resource blocks of the preferred resource blocks, is based, at least in part, on one or more downlink quality metrics for each of the preferred resource blocks;
• determine, based, at least in part, on the confirmation message, resource blocks to be used for the side-link communications with the at least one wireless node;
• and
• generate instructions to initiate the side-link communications with the at least one wireless node using the determined resource blocks.
