    Abstract: In embodiments, apparatuses, methods, and storage media may be described for mapping media access control (MAC) protocol data units (PDUs) that are used to transmit scheduling assignment (SA) discovery, and/or device-to-device (D2D) data. Embodiments herein may describe how one or more MAC PDUs may be mapped into a time resource pattern for transmissions (T-RPT). Embodiments herein may further describe examples of how and when a UE may skip subframes in transmissions of the SA and/or data. Additionally, embodiments herein may further describe examples of how a UE may behave if the UE cannot transmit one or more scheduled instances of SA or data. Additionally, embodiments herein may describe resolution of collisions of D2D discovery messages in the time domain. Other embodiments may be described and/or claimed.

    Abstract: Technology to support Hybrid Automatic Retransmission re-Quest (HARQ) for Carrier Aggregation (CA) is disclosed. For example, a device, at a processor residing on a User Equipment (UE), includes a sizing module and a window module. The sizing module can be configured to determine a first size of a first bundling window for a first Component Carrier (CC) and a second size of a second bundling window for a second CC. The window module can be configured to: generate a first virtual window comprising a selected number of DownLink (DL) sub-frames in the first bundling window that are added to DL sub-frames in the second bundling window; and generate a second virtual window comprising remaining DL sub-frames from the first bundling window that are not added to the first virtual window. The selected number of DL sub-frames can be proportional to a difference between the first size and the second size.

    Abstract: A UE configured for operating in a 5G NR network may decode signalling that schedules two physical downlink shared channels (PDSCHs) in a same time slot. When the UE is a reduced-bandwidth (RBW) reduced-capacity (RedCap) UE (RBW-RedCap UE), the UE may determine if a total number of allocated PRBs in an OFDM symbol for the two scheduled PDSCHs exceed a predetermined value when the two scheduled PDSCHs either partially or fully overlap in time in non-overlapping PRBs. The UE may also prioritize decoding of one of the two scheduled PDSCHs when the total number of allocated PRBs exceed the predetermined value and when the two scheduled PDSCHs either partially or fully overlap in time in non-overlapping PRBs. If a first of the two scheduled PDSCHs is a unicast PDSCH and a second of the two scheduled PDSCHs is a broadcast PDSCH, the UE may prioritize decoding of the unicast PDSCH.
