Claim 0:
1. A first apparatus comprising a processor, a memory, and communication circuitry, the first apparatus being connected to a network via the communication circuitry, the first apparatus further comprising computer-executable instructions stored in the memory which, when executed by the processor, cause the first apparatus to perform operations comprising:
determining whether conditions for requesting a resource grant are met, comprising determining the availability of resource grants for use in sidelink communication between the first apparatus and a third apparatus; and
if the conditions for requesting a resource grant are met, sending to a second apparatus a first request for a sidelink communications resource grant, the first request for a sidelink communications resource grant being for communications between the first apparatus and the third apparatus,
wherein the first request for a sidelink communication resource grant comprises a request for configuration information for another request for a sidelink communication resource grant, and wherein the instructions further cause the first apparatus to:
receive, from the second apparatus, configuration information, the configuration information pertaining to the first request for a sidelink communications resource grant;
receive, in response to the first request for a sidelink communications resource grant, a resource configuration for a second request for a sidelink communications resource grant; and
send, to the second apparatus, a second request for a sidelink communications resource grant,
wherein the configuration information comprises information regarding one or more shared sidelink communication resource grant request resources, and wherein the configuration comprises:
information regarding a pool of resources that are reserved for sidelink communication resource grant request transmission;
information regarding a probability, the information regarding probability being used by the first apparatus in determining whether to use the one or more shared sidelink communication resource grant request resources; and
a wait timer parameter, the wait time parameter being used by the first apparatus to evaluate whether a sidelink communication resource grant request transmission has failed.
