    Abstract: A user equipment (UE) configured for operation in a sixth generation (6G) network may perform a random access channel (RACH) procedure with a generation node B (gNB). The UE may encode a physical random access channel (PRACH) preamble for transmission in a PRACH occasion (RO) For carrier frequencies above 52.6 GHz, the UE may determine a Radio Network Temporary Identifier (RNTI) (i.e., either a RA-RNTI or a MsgB-RNTI) based on an index of the PRACH occasion RO index. The UE may also decode a response from the gNB that includes the RNTI. The UE may determine the RNTI based on the RO index in a time domain and the RO index in a frequency domain.

    Abstract: A generation node B (gNB) configured for aperiodic channel state information reference signal (CSI-RS) triggering and transmission may encode signalling for transmission to a user equipment (UE). The signalling to indicate an aperiodic Triggering Offset (aperiodicTriggeringOffset). The aperiodic Triggering Offset may comprise a slot offset. The gNB may encode a downlink control information (DCI) for transmission that may trigger transmission of a CSI-RS in one or more aperiodic CSI-RS resource set(s) (i.e., in one or more slots (n)). The DCI triggers transmission of the aperiodic CSI-RS within a triggered slot with the slot offset (i.e., the aperiodicTriggeringOffset). The gNB may transmit the CSI-RS in resource elements of the triggered slot in accordance with the slot offset, when CSI-RS resources are available in the slot at the slot offset. The gNB may postpone transmission of the aperiodically triggered CSI-RS to a first available downlink slot when the CSI-RS resources are not available in the triggered slot at the slot offset.

    Abstract: Various embodiments herein provide techniques related to hybrid automatic repeat request acknowledgement (HARQ-ACK) transmission in cellular networks. Some embodiments may relate to HARQ-ACK transmission in networks that use a relatively high carrier frequency (e.g., a carrier frequency above approximately 52.6 gigahertz (GHz)). Some embodiments may relate to HARQ-ACK codebook size determination for multi-physical downlink shared channel (PDSCH) scheduling. Some embodiments may relate to downlink control and HARQ-ACK transmission for multi-PDSCH scheduling. Other embodiments may be described and/or claimed.
