    Abstract: Systems and methods for PDCCH reliability are disclosed. The PDCCH may be improved by introducing multi-TRP, multi-beam or repeated, PDCCH transmission and reception. In some methods and systems, PDCCH is transmitted on multiple CORESETs (Control Resource Set), where each CORESET is associated with a TCI state. In some cases, it is beneficial if a UE can determine that multiple received DCIs are duplicates, in order not to duplicate the corresponding UE action. Methods and systems for DCI duplication determination are disclosed. In some methods and systems, PDCCH is transmitted in a single CORESET, where the CORESET is associated with multiple TCI states. Various ways to apply the different TCI states to different disjoint frequency parts of the CORESET or the whole CORESET are proposed. Furthermore, the TCI state used for PDCCH may be used for subsequent PDSCH reception as well, in some cases. The disclosure also presents methods and systems on how to apply multiple TCI states of a received PDCCH to a subsequent PDSCH reception.

    Abstract: Multiple mobility sets are maintained for nodes of radio networks. The sets comprise information such as: transmit and receive point identities; cell identities; beam identities; frequency channels; channel bandwidth; and black lists. The sets may be defined at different levels, such as network and physical (PHY) level. A network mobility set, e.g., a new-radio (NR) mobility set may, be determined by the gNB, the cell, the UE, or another device. Multiple radio access network nodes and UEs may exchange mobility set information to achieve a distributed mobility solution. A UE may monitor its orientation relative to a TRP, e.g., via use of an onboard MEMS gyroscope, and alter its beamforming parameters in response to changes in orientation and/or changes in TRP connection strength. Cell selection and reselection for beam based networks may use Single Frequency Network (SFN) broadcast of initial access signals without beam sweeping.

    Abstract: Logical Channel Prioritization (LCP) may be enhanced by accounting for Quality of Service (QoS) attributes of single hop and multi-hop paths. QoS attributes may be communicated as a QoS budget comprising a number of attributes, or as a single composite QoS “resistance” factor that quantifies the compounded impact of number of hops, latency, load conditions, and the like. The QoS budget or resistance may dynamically adjusted, and may be used by LCP to provide differentiated uplink resource allocation to data of the bearer or logical channel subject to different transmission paths between the transmitter and the receiver, for example. QoS budget and resistance information may be used to, e.g., enhance Buffer Status Report (BSR) and Scheduling Request (SR) operations.

    Abstract: Downlink Control Information (DCI) may be expanded, or enhanced, to allow nodes such as UEs, eNBs, NR-nodes, gNBs, and TRPs in M2M, IoT, WoT networks to coordinate activities on PHY, MAC, and RRC layers. For example, DCI fields may be added or enhanced to include, for example, information regarding time resource allocation, frequency resource allocation, mini-slot allocation, and or Code Block Group (CBG) transmission. Such information, or similar information, may be used in operations such as mini-slot operations, Code Block Group (CBG) transmission, group common Physical Downlink Control Channel (PDCCH), grant-free and grant-less operations, response to Beam Failure Recovery Request (BFRR), UL Transmit (TX) beam change, Quasi-Co-Location (QCL) operations, aperiodic CSI-RS transmission and interference measurement, Band Width Part (BWP) operations, and Multi-Transmission and Reception Point (TRP)/Multi-Panel.
