Abstract: Technology to support mapping for Hybrid Automatic Retransmission re-Quest (HARQ) for Carrier Aggregation (CA) is disclosed. One method can include a user equipment (UE) identifying, within a radio frame, a type 2 DownLink (DL) sub-frame within a virtual bundling window associated with a Secondary Component Carrier (SCC). The type 2 DL sub-frame can be virtually moved from a Primary Component Carrier (PCC) for HARQ-ACKnowledge (HARQ-ACK) multiplexing of the virtual bundling window. The UE can extract a Component Carrier Element (CCE) number for a first CCE used by a Physical Downlink Control CHannel (PDCCH) transmission corresponding to the type 2 DL sub-frame. The UE can determine a Physical Uplink Control CHannel (PUCCH) resource for carrying a HARQ-ACK multiplexing message based on the CCE number when a PCC window size of the PCC is greater than an SCC window size of the SCC.

Abstract: An apparatus and system to permit a UE idle or inactive mode to operate as an URLLC initiating device operating in a shared spectrum in a PRACH procedure are described. The UE receives a gNB control signal that contains an indication that the UE is able to operate as an initiating device and in response transmits a physical random access channel (PRACH) message within a Fixed Frame Period (FFP) of the UE. Transmission of the PRACH message is contingent on non-overlap of the PRACH message transmission with the idle period of a gNB FFP.

Abstract: Technology for an eNodeB operable to apply scrambling to coded bits transported via a physical downlink shared channel (PDSCH) to a user equipment (UE) is disclosed. The eNodeB can generate a code word that comprises coded bits for transmission to the UE. The UE can be a bandwidth-reduced low complexity (BL) UE or a coverage enhancement (CE) UE. The eNodeB can identify, for the BL UE or the CE UE, a scrambling sequence to be applied to the coded bits. The scrambling sequence can be initialized using a defined initialization value (cinit). The eNodeB can apply the scrambling sequence with the defined initialization value to the coded bits to obtain scrambled coded bits. The eNodeB can encode the scrambled coded bits for transmission to the UE via the PDSCH.

Abstract: An apparatus and system of supporting simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission are described. A user equipment (UE) that supports service types with different priority levels is configured by a 5th generation NodeB (gNB) to multiplex transmissions with different priorities on different serving cells in different bands. The UE multiplexes and prioritizes high priority (HP) and low priority (LP) uplink transmissions with and without simultaneous PUCCH and PUSCH transmissions based on repetition and scheduling request (SR).

Abstract: Various embodiments herein are directed to the request of Msg3 physical uplink shared channel (PUSCH) repetitions. In order to improve the coverage, repetition is supported for Msg3 PUSCH during the 4-step RACH procedure. In this case, either separate PRACH occasions or shared PRACH occasions with separate PRACH preambles may be configured to differentiate the enhanced UE that requests the Msg3 PUSCH repetition and legacy UEs that do not.

Abstract: An apparatus and system for deferring hybrid automatic repeat request (HARQ) feedback for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) transmissions in a time-domain duplexing (TDD) system are described. After an SPS PDSCH configuration indicating that deferral of the SPS HARQ feedback is enabled is received, a user equipment (UE) determines whether a PUCCH associated with a particular SPS PDSCH transmission is able to be transmitted on valid uplink (UL) symbols. The PUCCH carries a SPS HARQ-ACK bits to acknowledge the particular SPS PDSCH transmission. If the PUCCH is unable to be transmitted using the timing of the SPS PDSCH configuration, the transmission is deferred until the next valid occasion on which the PUCCH is able to be transmitted.

Abstract: Devices and methods of enhancing narrowband communications are generally described. NPSS and NSSS are modulated to include an additional bit that indicates a duplexing scheme, a raster frequency offset (zero or non-zero), an operating mode (in-band or standalone/guard-band) or frame timing used by the eNB. The NPSS modulation uses conjugate ZC sequences multiplied by a cover code for each OFDM symbol. The NMIB may provide additional information related to the operating mode or offset. NSSS cyclic shifts may be used to indicate the offset or TDD/FDD use, as may relative locations of the NPSS and NSSS. The NSSS may use symbol-level modulation and time domain cyclic shifts to indicate the frame timing.
