1. A method for wireless communications, comprising:
reserving, 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;
generating resource information for a plurality of second UEs associated with the first UE that identifies the portion of the 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 plurality of second UEs; and
transmitting a resource message to the plurality of 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 reserved for the first UE from the sidelink resource pool, wherein the search space for monitoring transmissions within the set of subchannels that are calculated based on the portion of the resources that have been reserved for the first UE from the sidelink resource pool comprises:
identifying a subset of the subchannels from the set of subchannels in the search space that fall outside of the portion of the resources that are reserved for the first UE; and
omitting transmissions received in the subset of the subchannels identified from the set of subchannels in the search space.
