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: Techniques discussed herein can facilitate reduced density CSI (Channel State Information)-RS (Reference Signals). One example embodiment can be employed at a UE (User Equipment) and can comprise processing circuitry configured to receive and process a configuration message that comprises one or more configuration parameters for one or more CSI (Channel State Information)-RS (Reference Signal) APs (Antenna Ports) of a configurable density CSI-RS. The configuration parameters indicate a density of CSI-RS resource per Physical Resource Block (PRB) per CSI-RS AP and a PRB offset. The processing circuitry is further configured to determine a set of REs (Resource Elements) for the one or more CSI-RS APs of the configurable density CSI-RS based on the one or more configuration parameters and perform measurements on the configurable density CSI-RS from the set of REs to determine one or more CSI parameters. The one or more configuration parameters are provided per CSI-RS resource configuration.

Abstract: Technology for a user equipment (UE) operable to perform downlink (DL) channel quality measurement reporting is disclosed. The UE can decode a system information block type y bandwidth reduced (SIBy-BR) received from an eNodeB. The SIB1-BR can instruct the UE to include a DL channel quality measurement report in a message 3 (Msg3) transmitted during a random access procedure between the UE and the eNodeB, wherein y is a positive integer greater than or equal to 1. The UE can determine a DL channel quality measurement for a DL channel between the UE and the eNodeB. The UE can encode the Msg3 for delivery over an uplink channel to the eNodeB. The Msg3 can be delivered during the random access procedure and can include the DL channel quality measurement report with the DL channel quality measurement.

Abstract: Methods, systems, and circuitries for configuring, measuring, and reporting channel state information are described. In one embodiment, an apparatus for a user equipment device (UE) includes processors configured to determine first channel state information (CSI) reference signal (RS) resource associated with a serving cell for the UE and determine a second CSI-RS resource associated with a non-serving cell for the UE. A first reference signal received in the first CSI-RS resource and a second reference signal received in the second CSI-RS resource are measured. First report quantities characterizing a channel between the UE and the serving cell are calculated based on the measurement of the first reference signal and second report quantities characterizing a channel between the UE and the non-serving cell are calculated based on the measurement of the second reference signal. The first and second report quantities are reported to the serving cell.
