Systems and methods to reduce network access latency and improve quality of service in wireless communication

Abstract

In a grant based system, a user equipment (UE) sends data in an uplink in a request-grant process. The UE first sending a scheduling request, a gNodeB processing the request and scheduling a grant sometime in future, then UE then either sending data if the grant is sufficient or requesting for another grant with more capacity to accommodate data sending. Such a proceeding could cause serious latency in network access. Described in the present patent disclosure are embodiments to reduce the access time by giving proactive grants through inspecting downlink (DL) data sent to the UE or uplink data being transmitted from the UE. The uplink data may be predictive since it maybe in lieu of requirement for sending a TCP acknowledgement for the DL TCP data scheduled earlier. For voice calls, a ML system for system may be deployed to predict when proactive UL grants may be given.
