Abstract: A user equipment (UE) receives physical downlink shared channel (PDSCH) in a downlink slot as scheduled using a downlink control indicator (DCI). The UE identifies that the downlink slot is part of a group of downlink slots based on the DCI and/or another DCI corresponding to the group. The UE identifies one or more uplink slots at which to transmit hybrid automatic repeat request (HARQ) feedback corresponding to the slots in the group, and transmits the HARQ feedback at one of these uplink slots. If HARQ feedback is not received, a semi-static codebook may prevent HARQ payload size misalignment.

Instead of encapsulating received data messages for storage, the data plane circuit in some embodiments encapsulates copies of the received data messages for storage. Accordingly, in these embodiments, the data plane circuit makes copies of the data messages that it needs to record.
