Abstract: Various embodiments herein provide techniques for dynamic transform precoding indication for a physical uplink shared channel (PUSCH) transmission and/or a msg3 transmission associated with a random access channel (RACH) procedure. For example, a downlink control information (DCI) that schedules a PUSCH may include a field to indicate whether transform precoding is enabled or disabled for the PUSCH. Additionally, or alternatively, the uplink grant received in the msg2 of the RACH procedure may include an indication of whether transform precoding is enabled or disabled for the msg3. Other embodiments may be described and claimed.

Abstract: A user equipment (UE) configured for operating in a fifth-generation (5G) new radio (NR) system may search for a 5G NR cell at Synchronization Signal (SS) block frequency positions associated with synchronization signal (SS) raster values. The UE may detect a Synchronization Signal Block (SSB) at one of the SS block frequency positions and may derive a cell reference frequency corresponding to a NR Absolute Radio Frequency Channel Number (NR ARFCN) value for the 5G NR cell from system information including a channel bandwidth. The frequency positions associated with the SS raster values are based on one or more Global Synchronization Channel Number (GSCN) values selected for the FR2 operating band n263. The cell reference frequency corresponds to one of a plurality of NR ARFCN values selected for the FR2 operating band n263.

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: Various embodiments herein provide techniques for multiple physical random access channel (PRACH) transmissions. For example, embodiments provide techniques to determine a random access response (RAR) window and/or a random access (RA)—radio network temporary identifier (RNTI) for multiple PRACH transmissions. Furthermore, embodiments relate to multiple PRACH transmissions triggered by physical downlink control channel (PDCCH) order. Other embodiments may be described and claimed.

Abstract: Various embodiments herein provide techniques for multiple physical random access channel (PRACH) transmissions for coverage enhancement. For example, embodiments may relate to PRACH window determination for multiple PRACH transmissions. In one example, the PRACH repetition window is determined in accordance with a number of consecutive valid PRACH occasions associated with a synchronization signal block (SSB). Other embodiments may be described and claimed.

Abstract: An apparatus for a UE includes processing circuitry coupled to memory. To configure the UE for shared spectrum channel access in a 5G-NR system, the processing circuitry is to decode a synchronization signal (SS)/physical broadcast channel (PBCH) block (SSB) to obtain a master information block (MIB). System information block 1 (SIB1) configuration information is determined using the MIB. The SIB1 configuration information is used to configure a Type 0 PDCCH common search space (CSS) set (CORESET). The processing circuitry is to monitor for a PDCCH in the Type 0 PDCCH CSS set over slots that include Type 0 PDCCH monitoring occasions. At least one of the slots includes the SSB and the CORESET multiplexed according to multiplexing pattern 1. The PDCCH is detected in at least one of the Type 0 PDCCH monitoring occasions. A SIB1 is decoded using downlink control information (DCI) received via the detected PDCCH.
