Abstract
Various embodiments herein provide techniques for hybrid automatic repeat request (HARQ)-acknowledgement (ACK) transmission with multi-cell scheduling (e.g., of physical downlink shared channels (PDSCHs) and/or physical uplink shared channels (PUSCHs). For example, embodiments include mechanisms for HARQ-ACK feedback timing determination, and formatting of HARQ-ACK feedback. Other embodiments may be described and claimed.
Claims21
One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors of a user equipment (UE) configure the UE to:
- detect a downlink control information (DCI) to schedule multiple physical downlink shared channels (PDSCHs), wherein the respective PDSCHs are to be transmitted from different cells and include different transport blocks (TBs), and wherein the DCI indicates one or more K1 values;
- determine an uplink resource for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback for the PDSCHs based on the one or more K1 values and a reference channel;
- and
- encode the HARQ-ACK feedback for transmission in the determined uplink resource.
One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors of a next generation Node B (gNB) configure the gNB to:
- encode, for transmission to a user equipment (UE), a downlink control information (DCI) to schedule multiple physical downlink shared channels (PDSCHs), wherein the respective PDSCHs are to be transmitted from different cells and include different transport blocks (TBs), and wherein the DCI indicates one or more K1 values;
- identify an uplink resource for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback for the PDSCHs based on the one or more K1 values and a reference channel;
- and
- receive the HARQ-ACK feedback from the UE in the uplink resource.
