Wireless Uplink Resource Set Allocation for Reliable UE Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in signal transmission and reception procedures, particularly in managing uplink resources for user equipment (UE) in diverse communication scenarios.
Innovation Solution
A method involving a user equipment (UE) transmitting a resource request for uplink transmission, receiving uplink resource allocation, and transmitting uplink data using allocated N uplink resources within a selected resource set, with the resource request including M candidate resource sets, and the allocation being indicated by downlink control information (DCI).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple candidate resource sets are configured for uplink transmission, then the reliability of resource allocation is improved, but the device complexity and signaling overhead increase
Solution Approach 1:
The resource sets are segmented into multiple candidate sets (first resource set, second resource set, etc.), each containing multiple uplink resources. This segmentation allows the system to provide multiple alternatives for resource allocation, improving reliability by enabling fallback options while keeping each individual resource set manageable in size and structure.
Solution Approach 2:
The network configures multiple candidate resource sets in advance before actual uplink transmission is needed. This preliminary configuration includes defining multiple resource sets with different resource configurations, which are then activated based on channel conditions or transmission requirements, reducing the complexity of real-time resource management decisions.
2Adaptability or versatility
If multiple candidate resource sets are configured for uplink transmission, then the adaptability to different transmission scenarios is improved, but the signaling overhead increases
Solution Approach 1:
The system dynamically selects which resource set to activate based on current transmission requirements and channel conditions. The network can indicate to the user equipment which candidate resource set should be used for a given transmission, allowing adaptability to different scenarios while managing signaling overhead by only transmitting necessary activation indicators rather than all resource configurations continuously.

AI summary
A method by which a user equipment (UE) transmits a signal in a wireless communication system according to at least one of embodiments disclosed in the present specification may comprise: transmitting, to a network, a first signal including a resource request for uplink transmission; receiving, from the network, a second signal including uplink resource allocation, in response to the resource request of the UE; and transmitting uplink data on the basis of the second signal, wherein the resource request of the UE included in the first signal includes M candidate resource sets, each having N uplink resources, one of the M candidate resource sets is allocated to the UE through the uplink resource allocation included in the second signal, and the uplink data can be transmitted through the N uplink resources included in one resource set allocated to the UE.
