Abstract: A computer-readable storage medium stores instructions to configure a UE for cross-carrier scheduling of data transmissions in a 5G NR and beyond wireless network, and to cause the UE to perform operations including decoding configuration signaling received from a base station. The configuration signaling indicates a first numerology parameter for a scheduling cell of the base station and a second numerology parameter for a scheduled cell of the base station. DCI is received via a PDCCH of the scheduling cell. The DCI schedules a DL data transmission in the scheduled cell of the base station. The DL data transmission is received via a PDSCH of the scheduled cell when a difference between the first numerology parameter and the second numerology parameter is smaller than or equal to a pre-configured numerology threshold value. The UE refrains from decoding the DL data transmission when the difference is greater than the threshold value.

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: 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: An apparatus of a user equipment (UE) includes processing circuitry, where to configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode higher layer signaling, the higher layer signaling including a default slot duration for a transmission of control signaling. The control signaling includes a synchronization signal (SS) and a physical broadcast channel (PBCH) signaling. Synchronization information within a SS block is decoded. The SS block is received within a SS burst set and occupying a plurality of symbols within a slot having the default slot duration. A synchronization procedure is performed with a next generation Node-B (gNB) based on the synchronization information within the SS block and the PBCH signaling.

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: Techniques for xPDCCH (5G (Fifth Generation) Physical Downlink Control Channel) design are discussed. In various aspects, xPDCCH can be transmitted via one or more OFDM (Orthogonal Frequency Division Multiplexing) symbols, with each OFDM symbol comprising a xPDCCH search space. Each xPDCCH search space can have one or two distinct xPDCCH sets, with each xPDCCH set having a xCCE (5G Control Channel Element) starting position that can be based on one of several predetermined rules, and can depend on one or more factors.
