Skipping Indication for Scheduled Uplink Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, there is a challenge in efficiently managing scheduled resources, particularly in scenarios where user equipment (UE) has insufficient data for all allocated uplink shared channel occasions, leading to wasted resources and inefficient use of network entity processing power.
Innovation Solution
The UE receives a control signal activating a time window of scheduled resources, allocates data to a subset of uplink shared channel occasions, transmits the data, and then sends a control message indicating that a second subset will be skipped, allowing the network entity to refrain from decoding and reallocate those resources to other UEs during retransmission windows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network entity decodes all allocated uplink shared channel occasions, then reliable data reception is ensured, but power consumption increases and system capacity decreases
Solution Approach 1:
The network entity performs decoding only on a subset of uplink shared channel occasions where data is actually present, rather than decoding all allocated occasions. The UE indicates which occasions contain data, allowing the network to skip decoding of empty occasions, thus reducing power consumption while maintaining reliable reception of actual data transmissions.
2Reliability
If the network entity allocates resources to all configured UEs, then system reliability is maintained, but resource utilization efficiency decreases
Solution Approach 1:
The network entity allocates decoding resources only to UEs that have data to transmit in each time window, rather than maintaining constant allocation for all configured UEs. The UE's indication of data presence allows dynamic resource allocation, improving overall system resource utilization while maintaining reliability for active users.
3Reliability
If the UE transmits on all allocated uplink shared channel occasions, then data transmission completeness is ensured, but resource waste increases when data is insufficient
Solution Approach 1:
The UE transmits data only on uplink shared channel occasions where it actually has data available, rather than forcing transmissions on all allocated occasions. This partial action approach prevents resource waste on empty transmissions while the network entity's selective decoding ensures complete data reception for occasions that do contain data.

AI summary
Methods, systems, and devices for wireless communication are described. The method may include a user equipment (UE) receiving a first control signal activating a first time window of scheduled resources that includes a set of uplink shared channel occasions. Further, the UE may allocate data to a first subset of the set of uplink shared channel occasions and transmit the data using the first subset. Moreover, the UE may transmit, after transmitting the data using the first subset of the set of uplink shared channel occasions, a second control signal indicating that a second subset of the set of uplink shared channel occasions will be skipped for uplink data transmission by the UE.
