User Equipment DCI Reception Segmentation for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE systems, user equipment (UE) experiences high workload and increased power consumption due to the need to process and receive all Downlink Control Information (DCI), leading to reduced efficiency in DCI reception.
Innovation Solution
A method where user equipment receives a first data packet carrying identity-related information, determines if it is intended for the UE, and only receives a second data packet containing corresponding DCI if the first packet indicates so, thereby reducing unnecessary processing and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment receives and processes all Downlink Control Information packets, then complete DCI reception is ensured, but workload and power consumption increase significantly
Solution Approach 1:
The DCI reception process is segmented into two stages: first receiving only the identity-related information packet to determine relevance, then receiving only the corresponding DCI packet if needed. This segmentation allows the UE to filter out unnecessary packets and process only relevant DCI, significantly reducing power consumption while maintaining reception completeness for relevant information.
Solution Approach 2:
The patent applies preliminary action by having the UE first receive and process the identity-related information packet before receiving the actual DCI packet. This preliminary step determines whether the DCI is relevant to the UE, allowing the UE to skip receiving unnecessary DCI packets entirely, thus reducing overall power consumption while ensuring complete reception of relevant DCI.
2Loss of information
If user equipment processes all received DCI packets, then no information is lost, but processing time and workload increase
Solution Approach 1:
The processing is segmented into a two-stage filter: first filtering by identity-related information, then filtering by receiving only the corresponding DCI packet. This segmentation eliminates the need to process all DCI packets, reducing processing time and workload while maintaining information completeness for relevant UE data.
Solution Approach 2:
The patent uses preliminary action by performing identity verification before DCI processing. The UE first checks the identity-related information packet to determine relevance, then only processes the corresponding DCI packet if the identity matches. This preliminary filtering action significantly reduces processing time and workload while ensuring no relevant information is lost.
3Adaptability or versatility
If user equipment receives all DCI packets, then comprehensive downlink control is obtained, but efficiency of DCI reception decreases
Solution Approach 1:
The DCI reception process is divided into two efficient stages: first receiving identity-related information to determine relevance, then receiving only the corresponding DCI packet. This segmentation maintains comprehensive downlink control coverage for relevant UE while significantly improving reception efficiency by eliminating unnecessary processing of irrelevant DCI packets.
Solution Approach 2:
The patent applies preliminary action by performing identity verification before full DCI reception. The UE first receives and processes the identity-related information packet, then only receives the corresponding DCI packet if the identity matches. This preliminary filtering action maintains comprehensive control coverage for relevant UE while dramatically improving reception efficiency by avoiding processing of irrelevant packets.

AI summary
The present invention relates to the field of communications technologies, and in particular, to a downlink information receiving method and sending method, user equipment, and a network device, to resolve a technical problem of relatively low efficiency of receiving DCI by UE. In embodiments of the present invention, first user equipment first receives a first data packet, and the first user equipment may determine whether the first data packet carries identity-related information of the first user equipment; and if the first data packet does not carry identity-related information of the first user equipment, the first user equipment does not need to receive a second data packet. For example, downlink information is DCI. In this way, time for receiving the DCI by the user equipment is reduced, efficiency of receiving the DCI by the user equipment is improved, and power consumption of the user equipment is reduced.
