RBG Allocation in Flexible Slots With Uplink Subbands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current communication systems, resource block groups (RBGs) are either exclusively used for uplink or downlink transmission, leading to inefficient utilization and slow information transfer due to unavailability of resources across subbands.
Innovation Solution
A method and apparatus for determining transmission resources by a user equipment (UE) and network device to utilize available RBGs for data transmission by configuring RBGs within downlink or flexible slots with uplink subbands, ensuring RBs do not overlap with guard or opposing subbands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RBGs are determined separately within UL BWP and DL BWP based on current manner, then uplink and downlink transmission can be performed, but all RBs within the RBG across the subband cannot be used for data transmission, resulting in low utilization efficiency of transmission resource
Solution Approach 1:
The patent segments the RBG determination process into separate downlink RBG determination and uplink RBG determination steps. The network device determines downlink RBGs based on downlink subband resources, and separately determines uplink RBGs based on uplink subband resources. This segmentation allows independent optimization of resource allocation for each direction, enabling better utilization of available resources while maintaining directional transmission integrity.
Solution Approach 2:
The patent introduces dynamic RBG determination where the network device can flexibly configure RBG sizes and quantities based on actual transmission conditions. The RBG configuration is not fixed but adapts to different subband resource availability, allowing the system to dynamically adjust resource allocation to maximize transmission efficiency and resource utilization under varying conditions.
2Reliability
If RBGs are determined separately within UL BWP and DL BWP, then directional transmission control is maintained, but resource utilization efficiency decreases due to unavailable resources across subbands
Solution Approach 1:
The patent applies local quality by determining RBGs based on local subband resource characteristics rather than uniform BWP-wide allocation. The network device evaluates downlink subband resources to determine downlink RBGs, and separately evaluates uplink subband resources to determine uplink RBGs. This localized approach allows each RBG to be optimized for its specific subband context, improving both control accuracy and resource utilization efficiency.
Solution Approach 2:
The patent segments the frequency spectrum into distinct subbands and determines RBGs independently within each subband for uplink and downlink. This segmentation enables precise control over which resources are allocated to which direction, maintaining transmission control accuracy while eliminating the waste of resources that occurs when entire RBGs are reserved for one direction and cannot be used for the other.

AI summary
The present disclosure belongs to the technical field of communications. Provided are a transmission resource determination method and apparatus, and a storage medium. The method comprises: by means of the interaction between a user equipment (UE) and a network device, the user equipment (UE) determining, according to a protocol agreement or indication information which is sent by the network device, an RBG in a downlink time slot or a flexible time slot in which an uplink sub-band is configured; and the network device determining, according to the protocol agreement or related indication information, the RBG in the downlink time slot or the flexible time slot in which the uplink sub-band is configured. Therefore, the problem of a resource utilization rate being low due to the unavailability of an edge RGB of a part of crossing sub-bands in a downlink time slot or a flexible time slot in which an uplink sub-band is configured is solved, and a downlink resource utilization rate is thus improved.
