User equipment initiated uplink timing advance acquisition for self-scheduled transmission

Abstract

Methods, systems, and devices for wireless communication are described. Various aspects relate generally to mechanisms according to which a user equipment (UE) may acquire an uplink timing advance for a UE self-scheduled transmission. Some aspects more specifically relate to a configuration of a set of random access resources associated with an uplink timing advance acquisition for UE self-scheduled transmissions. In some examples, the UE may receive information indicative of the set of random access resources via control signaling and may transmit a random access message in accordance with a random access resource from the set of random access resources to acquire an uplink timing advance for a UE self-scheduled transmission. The UE may transmit the random access message in accordance with the random access resource from the set of random access resources to indicate an intention of the UE to acquire an uplink timing advance for a UE self-scheduled transmission.
