Embodiment Construction

[0039] Those skilled in the art will recognize and understand that the details of the described examples are merely illustrations of some embodiments and that the teachings set forth herein apply to various alternatives.

[0040] The present invention relates to a wireless communication system with a paging mechanism followed by a Random Access (RA) response.

[0041] The present invention provides a method and system for reducing RA overhead when a UE is paged. This occurs without introducing additional overhead to the Paging Indication (PI) or Paging Message (PM). For the purposes of this invention, the term "paging related message" is intended to include PI and PM and any combination or equivalent thereof. RA preamble assignment signaling is usually implicit and has negligible impact on PI and / or PM length (if any). Instead of a 4-step contention-based RA process, a 2-step contention-free RA process is used. Therefore, the average RA latency of paged UEs is reduced.

Abstract

A method for enabling a wireless communication device to access services provided by a Radio Access Network, the method comprising paging one or more UEs, wherein a predetermined assigned RA preambleis communicated to the or each UE, at least partially in an implicit signalling over a paging related message

Description

technical field [0001] Embodiments of the present invention generally relate to a wireless communication system, and in particular to a method for enabling a wireless communication device such as a user equipment (User Equipment, referred to as UE) or a mobile device to access a radio access technology (Radio Access Technology, referred to as RAT) or radio access technology. Devices and methods for Radio Access Network (RAN for short). The present invention relates to, in particular but not limited to, reducing random access latency (latency) and overhead of paged User Equipment (UE) in New Radio (New Radio, NR) without introducing Improvements in or related to overhead. Background technique [0002] Wireless communication systems, such as third generation (3G) mobile phone standards and technologies, are well known. This 3G standard and technology has been developed by the Third Generation Partnership Project (3GPP). Third generation wireless communication is generally d...
