Abstract: Various embodiments herein provide techniques to provide a default transmission configuration indicator (TCI) state to a user equipment for receiving a physical downlink shared channel (PDSCH) that is scheduled using cross-carrier scheduling. In embodiments, a next generation Node B (gNB) may indicate the default TCI state to the UE using one or both of radio resource control (RRC) signaling and/or a medium access control (MAC) control element (CE). Other embodiments may be described and 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: A computer-readable storage medium stores instructions to configure one or more processors of a Further Reduced Capacity (F-RedCap) UE for operation in a 5G NR network, and to cause the F-RedCap UE to perform operations including decoding a PBCH to obtain a numerology parameter. A maximum resource block (RB) allocation is determined for a bandwidth associated with the numerology parameter. The maximum RB allocation is adjusted based on a reduced bandwidth associated with the F-RedCap UE to obtain an adjusted RB allocation. A maximum data rate is determined based on the numerology parameter and the adjusted RB allocation. Data is encoded for an uplink (UE) transmission to a base station. The UE transmission uses the maximum data rate.

Abstract: A user equipment (UE) configured for multi-slot physical downlink control channel (PDCCH) monitoring may decode higher-layer signalling comprising configuration information received from a gNodeB (gNB) that configure the UE with search space (SS) sets for multi-slot PDCCH monitoring. At least some slots of the SS sets may be indicated to have a PDCCH monitoring occasion (MO). A SS set may be configured in a number (Y) of consecutive non-overlapping slots (MO slots) within slot groups of a number (X) of consecutive non-overlapping slots. The number (X) of consecutive slots of the slot group may be at least twice the number (Y) of consecutive MO slots within each SS set. The number (X) of consecutive slots of the slot group and the number (Y) of consecutive MO slots within each SS set that comprise the PDCCH MO may also be based on a subcarrier spacing (SCS).

Abstract: A computer-readable storage medium stores instructions to configure a UE for communications using HD-FDD multiplexing In a 5G NR and beyond wireless network, and to cause the UE to perform operations. The operations include decoding DCI received via a PDCCH. The DCI indicates a dynamically scheduled DL reception on a PDSCH. The operations further include detecting an overlap between the dynamically scheduled DL reception and a semi-statically configured UL transmission on a PUSCH. The operations further include determining to perform one of the dynamically scheduled DL reception or the semi-statically configured UL transmission based on a start time (T0) of the semi-statically configured UL transmission and a pre-configured offset time (Toffset).

Abstract: Various embodiments provide techniques for channel state information reference signal (CSI-RS) transmission in a wireless cellular network. CSI-RS transmission bandwidth is determined based on a frequency domain allocation of a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), or a physical downlink control channel (PDCCH). A user equipment (UE) receives the CSI-RS according to the frequency domain allocation and a time domain allocation.
