VERFAHREN UND VORRICHTUNG ZUR EINLEITUNG EINES DIREKTZUGRIFFSVERFAHRENS

摘要

Embodiments of this application provide a method and an apparatus for initiating a random access process. The method includes: determining that a first time interval is greater than or equal to a first time threshold, and there is no available UL-SCH resource in a first time domain resource, where the first time interval is a time interval between a first moment of the first time domain resource and a second moment of a second time domain resource, and the second time domain resource is a time domain resource in which a grant-free UL-SCH resource is located; and initiating a random access process. In this application, when no PUCCH resource carrying a scheduling request is configured, sending of grant-free uplink transmission by a terminal device is prevented from being affected because the terminal device is prevented from frequently initiating a random access process, and a probability of initiating a random access process is reduced by limiting the first time threshold, to reduce a transmission latency of grant-free uplink data, and satisfy a service requirement of a service having a low latency requirement.
