Resource management and dynamic sidelink search space for new radio sidelink

An apparatus for wireless communications, comprising:

• at least one processor;
• and
• and memory coupled to the at least one processor, the memory including instructions executable by the at least one processor to cause the apparatus to:
• reserve, at a first user equipment (UE), a portion of resources from a sidelink resource pool available to a plurality of first UEs in a network;
• generate resource information for one or more second UEs associated with the first UE that identifies the portion of resources from the sidelink resource pool that have been reserved for the first UE, wherein the portion of the resources that are reserved for the first UE are to be used for sidelink communication between the first UE and the one or more second UEs;
• and
• transmit a resource message to the one or more second UEs that includes the resource information, wherein the resource information is used to configure search space for monitoring transmissions within a set of subchannels that are calculated based on the portion of the resources that have been allocated to the first UE from the sidelink resource pool.

A method for wireless communications, comprising:

• receiving, at a first user equipment (UE), a resource message from a second UE that includes a resource information regarding a portion of resources that have been reserved by the second UE from a sidelink resource pool available;
• configuring a search space for sidelink communication between the first UE and the second UE based on the resource information, wherein the search space is a subset of subchannels calculated based in part on the portion of resources that have been reserved by the second UE;
• monitoring, at the first UE, the subset of subchannels for sidelink transmissions from the second UE that are within the search space;
• and
• decoding the sidelink transmissions from the second UE based on the monitoring of the subset of subchannels.
