Hyper Cell Uplink Access via Preconfigured Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication systems, user equipment (UE) transitions from an idle state to a connected state slowly due to complex signaling procedures, leading to inefficiencies, especially in hotspot areas with dense small cell deployments where mobility management becomes challenging.
Innovation Solution
The introduction of a hyper cell concept, where a network follows the UE, allowing the UE to operate in a power saving state with preconfigured dedicated user equipment identity (DUI) and resources, enabling quick entry into an activated state without performing a complex RRC connection setup process, using grant-free resources and tracking signals for efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE performs complex signaling procedures (random access and RRC connection setup) to transition from idle state to connected state, then the UE can establish proper communication connection, but the transition time is long and access efficiency is low
Solution Approach 1:
The network pre-configures uplink resources and transmission parameters for UE in idle state before actual data transmission is needed. This preliminary configuration includes allocating uplink grant resources, setting transmission power parameters, and configuring reference signals, so that when UE needs to access the network, it can immediately transmit data without waiting for the complete random access and RRC connection setup procedure.
Solution Approach 2:
The patent extracts the essential communication functionality from the complete RRC connection setup procedure. By allowing UE to transmit data in idle state using pre-configured resources, the patent separates the data transmission function from the full connection establishment process, enabling selective activation of only the necessary communication components rather than the entire connection setup sequence.
2Productivity
If UE enters connected state frequently to send uplink data, then data transmission can be performed, but signaling overhead and network load increase
Solution Approach 1:
UE in idle state is empowered to autonomously transmit uplink data using pre-configured resources without needing to first transition to connected state. The UE self-manages the transmission by selecting appropriate pre-configured resources, adjusting transmission parameters based on channel conditions, and directly injecting data into the uplink channel, thereby eliminating the need for control plane signaling that would otherwise be required to establish connection state.
Solution Approach 2:
The patent implements partial connection establishment by configuring only the minimal necessary resources for uplink transmission in idle state, rather than establishing the complete connected state with all its associated signaling and resource allocations. This partial action approach provides just enough capability for immediate data transmission without the full overhead of complete connection setup.
3Area of stationary object
If traditional cell-based mobility management is used in dense small cell deployments, then coverage can be provided, but mobility management becomes challenging and complex
Solution Approach 1:
The patent merges multiple small cell coverage areas into a unified hyper cell structure, where a single set of pre-configured uplink resources and transmission parameters serves the entire hyper cell region. This consolidation reduces mobility management complexity by eliminating the need for separate resource configurations and handover procedures for each individual small cell, while still providing comprehensive coverage across all constituent cells.
Solution Approach 2:
The pre-configured uplink resources and transmission parameters are designed to be universally applicable across the entire hyper cell region, serving multiple functions including initial access, data transmission, and mobility management. This universal configuration eliminates the need for cell-specific resource allocation and simplifies the UE's ability to operate across different small cells without requiring complex mobility procedures.

AI summary
Embodiments of the present invention provide a communication method and apparatus applied to a hyper cell. The method includes: determining, by UE in a power saving state that is in a hyper cell, that there is to-be-sent uplink data, where the hyper cell includes a plurality of TPs, the hyper cell identifies the UE by using a DUI, and the UE in the power saving state reserves the DUI; sending, by the UE, an uplink instruction message to a controller based on the DUI by using a preconfigured uplink resource, where the uplink instruction message is used to instruct the UE to enter an activated state; and sending, by the UE in the activated state, the uplink data to the controller. In the embodiments of the present invention, not only the UE in the power saving state reserves the DUI, but also the uplink resource is preconfigured for the UE. Therefore, when the UE has the to-be-sent uplink data, the UE can quickly enter the activated state based on the DUI by using the uplink resource, with no need to perform a complex RRC connection setup process. This improves efficiency of entering the activated state by the UE.
