    摘要: Systems for providing coverage enhancement for Msg 3 PUSCH and PUCCH carrying the HARQ-ACK for Msg4 of PRACH initial access are described. The gNB provides a 2-bit aggregation factor for transmission of the Msg3 PUSCH in an RAR UL grant field. The PUSCH frequency resource allocation field is limited to 12 bits so that the RAR has an overall number of bits that is the same as an RAR that does not contain the aggregation factor. A default PUSCH TDRA table includes a field to indicate a repetition level for Msg3 PUSCH transmission. For retransmissions, fields in DCI format 0_0 are repurposed to indicate an aggregation factor. Inter-slot frequency hopping may be configured by higher layers. Different PRACH resources are used to indicate UE coverage status.

    摘要: The disclosure describes mechanisms for reliability enhancement on control channel and data channel and mechanisms in URLLC. An apparatus of a RAN node for URLLC includes baseband circuitry to configure at least one DCI for scheduling transmission of at least one PDSCH content having same information. For each DCI, the baseband circuitry determines a CORESET for transmitting the DCI. The disclosure further describes mechanisms for the support of low latency transmission in URLLC. To improve peak data rate and spectrum efficiency in FDD system, the RAN node configures a DCI for scheduling data transmission using blank resources of a self-contained slot structure. Further, CBG-based transmission with separate HARQ-ACK feedback is provided to configure a DCI for scheduling data transmission of a TB and to divide the TB into multiple CBGs, and to configure uplink control data to carry separate HARQ feedback for the CBGs.

    摘要: Devices and methods of enhanced coverage (EC) paging are generally described. An evolved Node-B (eNB) may transmit multiple EC paging messages to user equipment (UE) over at least one paging cycle. Each EC paging message may contain the same paging information. The UE may combine the individual EC paging messages to achieve a predetermined link budget and subsequently may decode the EC combined paging message to determine whether the combined paging message is directed to the UE. The EC paging messages may contain information for more than one UE and a legacy P-RNTI or a specific P-RNTI for EC mode UEs. The EC paging messages may be transmitted in legacy occasions over several paging cycles or non-legacy paging occasions over one or more paging cycles. The EC paging messages may be transmitted in continuous or non-continuous subframes in a particular paging cycle.
