Abstract: Technology for a user equipment (UE) operable to determine a transport block size (TBS) is disclosed. The UE can determine a number of assigned resource elements (REs) in one or more symbols for a transport block. The UE can determine a reference number of REs per physical resource block (PRB) in the transport block based on a reference number of REs for the transport block corresponding to each PRB and an assigned number of PRBs for the transport block. The UE can determine a TBS for the transport block based at least on the reference number of REs per PRB in the transport block. The UE can encode information in a selected transport block for transmission via a physical uplink shared channel (PUSCH) to a Next Generation NodeB (gNB) in accordance with the TBS determined at the UE.

Abstract: Provided herein are a method and an apparatus for interference measurement using a beam management reference signal (BM-RS). The disclosure provides an apparatus for a user equipment (UE), comprising circuitry configured to: decode one or more beam management reference signals broadcasted by a Transmission Reception Point (TRP) in a cell, wherein the one or more beam management reference signals are used by the TRP to perform beam management for respective one or more other UEs in the cell; and measure interference from the one or more other UEs in the cell based on the decoded one or more beam management reference signals. According to some embodiments, the overhead for the interference measurement can be reduced since it is not necessary to allocate a separate CSI-RS for the purpose of interference measurement.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for selecting a TCI-State for receiving downlink transmissions. In one example a processor/UE is configured to determine one or more candidate TCIs for a downlink slot; determine a scheduling offset between a physical downlink shared channel (PDSCH) and a physical downlink control channel (PDCCH); prioritize the candidate TCIs based on the scheduling offset; identify a highest priority candidate TCI; and select the highest priority candidate TCI for receiving the PDSCH.

Abstract: Various embodiments provide techniques to determine a TBS for use with 1024 QAM communications that use more than one multiple input, multiple output (MIMO) layer based on a reference TBS for use with 1024 QAM communications that use a single MIMO layer. The reference TBS may be determined based on a TBS index and a resource allocation for the communication. The TBS index may be determined based on a modulation and coding scheme (MCS) index. Other embodiments may be described and claimed.
