ACKNOWLEDGEMENT SIGNALING FOR MULTI-PUSCH AND MULTI-PDSCH SCHEDULING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17593302 titled 'ACKNOWLEDGEMENT SIGNALING FOR MULTI-PUSCH AND MULTI-PDSCH SCHEDULING

Simplified Explanation

The patent application relates to acknowledgement signaling sent by a user equipment (UE) in response to downlink control information (DCI) received from a base station. The DCI schedules the use of multiple physical uplink control channels (multi-PUSCH) or multiple physical downlink control channels (multi-PDSCH). The acknowledgement signaling informs the base station whether the DCI scheduling the multi-PUSCH/multi-PDSCH was received or not. This allows the base station to reclaim the scheduled resources if the UE remains unaware of them.

• The patent application discusses methods for performing acknowledgement signaling, including the use of HARQ-ACK codebooks and aperiodic sounding reference signals (A-SRS).
• The application contemplates embodiments involving DCI received across multiple component carriers of different serving cells of the UE.
• It also discusses acknowledgment signaling according to multi-PUSCH/multi-PDSCH subgroups, monitoring windows, acknowledgment signaling enablement/disablement, and the use of DCI to trigger acknowledgment signaling.

Potential applications of this technology:

• This technology can be applied in wireless communication systems that use multiple physical uplink control channels or multiple physical downlink control channels.
• It can be used in 5G and future generations of wireless networks to improve resource allocation and scheduling efficiency.

Problems solved by this technology:

• The technology solves the problem of the base station not being aware of whether the UE has received the DCI scheduling the multi-PUSCH/multi-PDSCH.
• It addresses the issue of wasted resources when the UE remains unaware of the scheduled resources.

Benefits of this technology:

• Improved resource allocation and scheduling efficiency in wireless communication systems.
• Reduced waste of resources due to the ability to reclaim scheduled resources if the UE remains unaware of them.

Original Abstract Submitted

Systems and methods disclosed herein relate to acknowledgement signaling sent by a user equipment (UE) in response to downlink control information (DCI) received from a base station that schedules the use of multiple physical uplink control channels (multi-PUSCH) or multiple physical downlink control channels (multi-PDSCH). Acknowledgement signaling may inform the base station that DCI scheduling the multi-PUSCH/multi-PDSCH was received (or not), so that the base station may reclaim those scheduled resources in the case that the UE remains unaware of them. Methods for performing this signaling include, e.g., the use of HARQ-ACK codebooks (whether in a semi-static or dynamic manner), and aperiodic sounding reference signals (A-SRS). Embodiments involving such DCI received across multiple component carriers of different serving cells of the UE are contemplated. Acknowledgment signaling according to multi-PUSCH/multi-PDSCH subgroups, monitoring windows, acknowledgment signaling enablement/disablement, and the use of DCI to trigger acknowledgment signaling are also discussed.
