Benefits of technology

The patent text describes a communication device and method for quickly accessing a Non-Standalone (NSA) 5G NR network. The invention helps to reduce latency and improve the overall performance of the network. The technical effects of this patent include improved speed, reliability, and overall user experience.

Problems solved by technology

In the early stages of transition to 5G network, 5G cells may be partially deployed leading to incomplete or partial 5G coverage.
There are certain existing initial access procedures proposed for NSA 5G NR implementation, which are complicated and time consuming, for example, as a result of the use of extensive cell (base station) search and / or beam search operations in the initial access procedure.

Embodiment Construction

[0012]Certain embodiments of the disclosure may be found in a communication device and method for low-latency initial access to NSA 5G NR network. Existing initial access procedures typically include two main steps, cell (or base station) search on the downlink and random access (RA) on the uplink. 5G NR-based systems or communication devices typically rely on directional beamforming in order to create a viable connection. The beamforming direction may be required to be learned and may be used in the IA process, which may be more complicated relative to communication systems operating at lower carrier frequencies.

[0013]Further in certain scenarios, a 5G-ready device, such as a customer premise equipment (CPE), may be situated at a distance which is beyond transmission range of a base station, and hence reception of the RF signal at the CPE may be adversely affected. Lack of refraction and diffraction in high radio frequencies also limits availability of links to line-of-sight (LOS) ...

Abstract

A communication device initiates beam acquisition in a receive-only mode. Beam reception is set to an omni mode in which different beams of RF signals are receivable at the communication device from different directions. A primary signal synchronization (PSS) search is executed from each signal synchronization block location based on control information acquired directly from a first base station over a long-term evolution (LTE) control plane link or from a customer premise equipment (CPE) or user equipment (UE) that is in a radio resource control (RRC) connected state. The communication of the beam of RF signals that has highest received signal strength is activated in a new radio (NR) frequency to the UE or the CPE based on at least a PSS detected in the PSS search, for low-latency non-standalone access to the beam of RF signals in NR frequency at the UE or the CPE.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS INCORPORATION BY REFERENCE[0001]None.FIELD OF TECHNOLOGY[0002]Certain embodiments of the disclosure relate to a communication device in a wireless telecommunication system. More specifically, certain embodiments of the disclosure relate to a communication device and method for low-latency initial access to non-standalone (NSA) next (5th) generation (5G) new radio network.BACKGROUND[0003]5G is the next generation of wireless telecommunication technology that delivers much faster data rate as compared to long term evolution (LTE or 4G) technology. Currently, there are two solutions proposed for 5G networks, known as Non-Standalone (NSA) and standalone (SA). In the Non-Standalone (NSA), the 5G networks will be supported by existing LTE infrastructure. In the early stages of transition to 5G network, 5G cells may be partially deployed leading to incomplete or partial 5G coverage. Thus, the 5G network needs to be interworked with the existing LTE n...
