Scheduling Information Segmentation for WLAN Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing WLAN technologies face inefficiencies in transmitting scheduling information, particularly in indicating how public information can be used by receiving ends to parse user-specific information, leading to resource wastage and prolonged transmission times.
Innovation Solution
A method and device for transmitting scheduling information that includes acquiring scheduling results for User Equipment (UEs) and transmitting scheduling information comprising a first type (public) and a second type (user-specific) of scheduling information. The first type includes information for parsing the second type, determining resource scheduling conditions for UEs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scheduling information for all users is transmitted on the main channel and repeated on secondary channels according to traditional manner, then complete scheduling information can be delivered to all users, but transmission time increases and resource waste occurs
Solution Approach 1:
The patent segments scheduling information into two types: first type (public scheduling information) transmitted on main channel, and second type (user-specific scheduling information) transmitted only on secondary channels where resources are allocated. This segmentation allows receivers to obtain public information quickly while only processing user-specific information for their allocated resources, reducing overall transmission time and resource waste.
2Adaptability or versatility
If scheduling information is transmitted using large bandwidth, then more users can be scheduled, but overhead increases and transmission efficiency decreases for small data packets
Solution Approach 1:
The patent applies local quality by transmitting user-specific scheduling information only on secondary channels where actual resource allocations occur, rather than uniformly across all channels. This allows the system to adapt the information transmission to the local resource allocation pattern, reducing overhead for users with small data packets while maintaining capacity for multiple users.
3Ease of operation
If public scheduling information includes all user-specific details, then complete parsing information is available, but information overhead and processing complexity increase
Solution Approach 1:
The patent extracts user-specific scheduling information from the main public scheduling information block and transmits it separately on secondary channels. This extraction allows receivers to first obtain compact public scheduling information on the main channel, then selectively retrieve only their relevant user-specific information from secondary channels, reducing overall information overhead and processing complexity.

AI summary
A method and a device for transmitting or receiving scheduling information are described. In the method for transmitting scheduling information, information about a scheduling result of resources to be occupied by one or more User Equipment (UEs) is acquired; and scheduling information including a first type of scheduling information and a second type of scheduling information is transmitted to the one or more UEs according to the information about the scheduling result. The first type of scheduling information includes information for parsing the second type of scheduling information, and the scheduling information determines a resource scheduling condition of the user.
