AI Technical Summary

Technical Problem

In wireless communications systems, self-scheduled uplink transmissions by user equipment (UE) incur substantial processing costs at the network side due to blind channel estimation and decoding, particularly when uplink resource pools are not differentiated for control information and data transmissions.

Method used

The network entity allocates separate uplink resource pools for uplink control information (UCI) and UE self-scheduled data transmissions, allowing the UE to transmit UCI messages that reserve resources for physical uplink shared channel communications, reducing the need for blind decoding on data transmission resources.

Benefits of technology

This approach reduces the network's processing load by minimizing blind decoding on data resources, optimizing resource utilization and improving transmission efficiency.

Abstract

Methods, systems, and devices for wireless communications are described. A network entity may allocate two resource pools for user equipments (UEs) to perform self-scheduled uplink transmission to the network entity. For example, the network entity may allocate a first uplink resource pool for uplink control information (UCI) and a second uplink resource pool for the UE self-scheduled data transmissions (e.g., physical uplink shared channel (PUSCH) communications that carry data). A UE may transmit a UCI message via a resource of the first uplink resource pool that reserves or schedules a resource of the second uplink resource pool for a PUSCH communication. Accordingly, the network entity may perform blind-decoding on the resources of the first resource pool but may refrain from performing blind decoding on the resources of the second resource pool.
