  • Publication number: 20210298075
    Abstract: Systems and methods of adjusting contention window size (CWS) in a LBT procedure for both UL and DL unlicensed spectrum transmissions are described. The UE makes a HARQ-ACK determination for at least one code block group (CBG) of a transport block (TB) in a reference burst from a base station, determines whether the HARQ-ACK determination for the CBG meets a predetermined number of NACKs, transmits to the base station a single bit HARQ-ACK feedback for the TB that is dependent on whether the predetermined number of NACKs has been met, and receives or determines the adjusted CWS and uses the adjusted CWS for communication with the base station.

  • Publication number: 20210251016
    Abstract: 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.
