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.

Abstract: A user equipment (UE) configured for operation in a fifth-generation new radio (5G NR) system may be configured for multi physical downlink shared channel (PDSCH) scheduling and may decode a first downlink control information (DCI) and a second DCI received from a gNodeB (gNB). The first DCI may schedule multiple PDSCHs and the second DCI may schedule one or more PDSCHs. The UE may check the timing relations of the scheduled PDSCHs for validity when the first DCI and the second DCI end at a same symbol. When the multiple PDSCHs scheduled by the first DCI and the one or more PDSCHs scheduled by the second DCI are determined to have overlapping time spans, the UE may identify all the PDSCHs scheduled by the first DCI the second DCI as invalid.

Abstract: The present disclosure is related to listen-before-talk (LBT) operations for multiple consecutive physical uplink shared channel (PUSCH) transmissions scheduled by a single downlink control information (DCI) or multiple DCIs. In a fifth generation (5G)/new radio (NR) system operating in an unlicensed spectrum, when multiple physical uplink shared channel (PUSCH) transmissions are scheduled (e.g., by one or more DCIs), and if LBT operation has failed before the start of a first PUSCH transmission of the multiple PUSCH transmissions, an LBT type and cyclic prefix (CP) extension for a subsequent PUSCH transmission of the multiple PUSCH transmissions is determined. In some examples, the multiple PUSCH transmissions are consecutive PUSCH transmission. Other embodiments may be described and/or claimed.

Abstract: Embodiments herein provide techniques for indication of a system frame number (SFN) in and/or associated with a random access response (RAR) for a random access procedure. A UE may transmit a physical random access channel (PRACH) preamble in a PRACH occasion (e.g., in a Msg1 or MsgA) and monitor for a message (e.g., Msg2 or MsgB) in a RAR window. The RAR window may be greater than one frame. The Msg2 or MsgB (e.g., a downlink control information (DCI) and/or a medium access control (MAC) RAR) may indicate the SFN associated with the RACH occasion. The UE may determine whether the message is for the UE or another UE based on the SFN. Other embodiments may be described and claimed.

Abstract: Various embodiments herein provide techniques for grant-based and configured grant physical uplink shared channel (PUSCH) transmissions in New Radio (NR) systems operation in unlicensed spectrum. Some embodiments relate to identification, based on an index to a table, a combination of a listen-before talk (LBT) type, an offset, and a channel access priority class (CAPC). Some embodiments relate to selecting, based on a duration of a first uplink (UL) transmission that is to follow a received downlink (DL) transmission, one of CAT-1 LBT and CAT-2 LBT. Other embodiments may be described and/or claimed.

Abstract: Various embodiments herein provide techniques for handling overlap of uplink (UL) channels (e.g., UL control channels and/or UL data channels), such as prioritizing and/or multiplexing uplink channels. In some embodiments, the overlapped channels may have different priorities. Other embodiments may be described and claimed.

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.
