UPLINK CONTROL CHANNEL GROUP AND CROSS-CARRIER SCHEDULING FOR USER EQUIPMENT COOPERATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18264712 titled 'UPLINK CONTROL CHANNEL GROUP AND CROSS-CARRIER SCHEDULING FOR USER EQUIPMENT COOPERATION

Simplified Explanation

The abstract describes a method for uplink control channel group and cross-carrier scheduling in cooperative communications of a virtual UE. The UE reports a cooperative configuration with member UEs of a virtual UE and reports associations between component carriers allocated to a cell group and each member UE. The UE then receives an uplink control transmission configuration message dividing member UEs into assigned uplink control transmission groups and assigns component carriers into CC sets, where each CC set is assigned to an uplink control transmission group. The UE also receives an uplink scheduling message from a serving base station, which includes an uplink schedule for CCs within the CC set assigned to an uplink control transmission group associated with the UE.

• Simplified Explanation:

- Method for uplink control channel group and cross-carrier scheduling in cooperative communications of a virtual UE. - UE reports cooperative configuration with member UEs and associations between component carriers and each member UE. - UE receives uplink control transmission configuration message dividing member UEs into groups and assigns component carriers to CC sets. - UE receives uplink scheduling message from base station with schedule for CCs within assigned CC set.

• • Potential Applications:

- 5G networks - Internet of Things (IoT) devices - Mobile communication systems

• • Problems Solved:

- Efficient allocation of resources in cooperative communications - Improved uplink control channel management - Enhanced cross-carrier scheduling

• • Benefits:

- Increased network efficiency - Enhanced communication reliability - Optimal resource utilization

• • Potential Commercial Applications:

- Telecommunications companies - Network equipment manufacturers - IoT device manufacturers

• • Possible Prior Art:

- Prior art related to uplink control channel management in wireless communication systems - Prior art on cross-carrier scheduling techniques in cellular networks

• • Unanswered Questions:

1. How does this method handle interference mitigation in cooperative communications? 2. What impact does this method have on overall network latency and throughput in a dense deployment scenario?

Original Abstract Submitted

Uplink control channel group and cross-carrier scheduling is disclosed for cooperative communications of a virtual UE. In an aspect, a UE reports a cooperative configuration with member UEs of a virtual UE and reports associations between a plurality of component carriers (CCs) allocated to a cell group and each member UE of the virtual UE. The UE may then receive an uplink control transmission configuration message dividing each member UE into an assigned uplink control transmission group and assign one or more component CCs into one or more CC sets, wherein each CC set is assigned to each uplink control transmission group. The UE may receive an uplink scheduling message from a serving base station, wherein the uplink scheduling message includes an uplink schedule for CCs within the CC set assigned to an uplink control transmission group associated with the UE. Other aspects and features are also claimed and described.
