    Abstract: In one embodiment, an apparatus includes memory storing instructions and processing circuitry coupled to the memory. The processing circuitry is to implement the instructions to select a resource block group (RBG) size configuration from a set of RBG size configurations based on a bandwidth part (BWP) size. Each RBG size configuration is to indicate RBG sizes associated with respective ranges of BWP sizes, and the RBG sizes are to indicate a number of frequency-domain physical resource blocks (PRBs) for physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) transmissions. The processing circuitry is further to implement the instructions to allocate PRBs for communication between the gNB device and a user equipment (UE) device via the PDSCH or PUSCH transmissions based on the selected RBG size, and to encode downlink control information (DCI) that indicates the allocated PRBs for transmission to the UE device.

    Abstract: Disclosed herein are timing determination techniques for 5G radio access network (RAN) cells. According to various such techniques, a user equipment (UE) may receive a downlink (DL) scheduling command to schedule a DL data transmission from a base station. The UE may identify a scheduled slot for transmission of hybrid automatic repeat request (HARQ) feedback corresponding to the DL data transmission based on a received slot of the DL data transmission and an applicable slot offset value. The applicable slot offset value may indicate a number of slots by which the received slot precedes the scheduled slot. The applicable slot offset value may be identified from a value set based on an indicator comprised in the DL scheduling command, or may be identified using the various other techniques described herein.

    Abstract: A device of a User Equipment (UE) includes a soft buffer including a plurality of soft buffer partitions to store a plurality of soft bits for a number of hybrid automatic retransmission request (HARQ) processes, wherein the number of HARQ processes includes first HARQ processes corresponding to a first Time Transmission Interval (TTI) Type of a first duration (TTI Type 1), and second HARQ processes corresponding to a second TTI Type of a second duration (TTI Type 2) shorter than the first duration. The device further includes processing circuitry to communicate with a base station in a cellular network, the processing circuitry further to effect a dynamic switching between a TTI Type 1 communication mode and a TTI Type 2 communication mode, and to selectively access the soft buffer partitions to perform, based on the switching, at least one of the first HARQ processes and the second HARQ processes.

    Abstract: Methods, apparatus, and systems are provided for signalling transmissions using carriers of different numerologies. In one example, a baseband processor of a base station is configured to perform operations including encoding a first signal to be transmitted on a physical downlink control channel (PDCCH) on a first component carrier with a first subcarrier spacing. The first signal includes downlink control information (DCI) indicating resources for a second signal to be transmitted on a second component carrier with a second subcarrier spacing. The DCI is based on a predetermined numerology and respective numerologies of the first component carrier and the second component carrier are different from one another in accordance with the first subcarrier spacing and the second subcarrier spacing. The baseband processor is configured to cause transmission of the first signal on the PDCCH.
