Abstract: Network devices and systems in 5G and new radio (NR) infrastructures can utilize beam management operations to ensure communications for beam management procedure triggering including beam reporting, even during fall-back mode when the current receive (Rx) beam for downlink (DL) and transmit (Tx) beam for uplink (UL) fail. Additionally, reduction in overhead can be achieved with a reference beam pair link based beam reporting in a fall-back mode or not. This beam reporting can be a group based beam reporting and based on Reference Signal Received Powers (RSRPs) of beams and a differential RSRP corresponding thereto.

Abstract: Technology for a user equipment (UE) operable for beam management is disclosed. The UE can be configured to decode, at the UE, a transmission configuration indicator (TCI), wherein the TCI is configured for a control channel and a data channel for all bandwidth parts (BWPs) of the UE or all component carriers (CCs) of the UE. The UE can be configured to decode, at the UE, a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS) for beam management with a repetition parameter set to “ON” transmitted in one BWP or one CC in a first set of symbols. The UE can be configured to identify, at the UE, a scheduling restriction for the first set of symbols for the control channel and the data channel, wherein the scheduling restriction indicates that downlink transmission in the first set of symbols is not expected.

Abstract: In some embodiments, an apparatus of a Fifth Generation (5G) NodeB (gNB) comprises one or more baseband processors to encode one or more channel state information reference signals (CSI-RS) to be transmitted to a user equipment (UE). The one or more CSI-RS signals comprise a complex sequence mapped to a resource element (RE) such that all CSI-RS ports use an identical sequence for the one or more CSI-RS signals in a symbol. In other embodiments, the gNB comprises one or more baseband processors to encode a scrambling identity (ID) configuration for one or more demodulation reference signals (DMRS), wherein the scrambling ID configuration indicates one of two scrambling IDs to be signaled to a UE.

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.
