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: An NR network slicing architecture may be used to facilitate network slice discovery and selection. Mechanisms to discover and select network slices may differ depending on whether a user equipment is in an idle mode or a connected mode. Further, in various examples, the network slice discovery and selection may be performed by a UE, a radio access network (RAN), or a core network (CN), based on a variety of selection criteria.

Abstract: Flexibly configured containers consisting of resources within time-frequency blocks may be used to support multiple numerologies in new radio architectures. Uplink control may be defined in resources within a container, or in dedicated resources, by various nodes. Sounding reference signal resources may be dynamically configured for each numerology. The sequence length may be adapted, as well as the time domain location of symbols. Time, frequency, and orthogonal resources may be allocated via a downlink control channel or a radio resource control. Sounding reference signals may be pre-coded, and pre-coding weights may be based on a codebook or non-codebook approaches, e.g., via a radio resource control or a downlink RRC or DL control channel. Pre-coded sounding reference signals may be adapted to user equipment antenna configuration. Further, NR-SRS may be used as UL demodulation RS (DM-RS).

Abstract: The application describes an apparatus including a non-transitory memory including instructions to perform random access in a beam sweeping network having a cell. The network includes a downlink sweeping subframe, an uplink sweeping subframe and a regular sweeping subframe. The apparatus also includes a processor operably coupled to the non-transitory memory. The processor is configured to execute the instructions of selecting an optimal downlink transmission beam transmitted by the cell during the downlink sweeping subframe. The processor is also configured to execute the instructions of determining an optimal downlink reception beam from the optimal downlink transmission beam. The processor is further configured to execute the instructions of determining a random access preamble and a physical random access channel (PRACH) resource via resource selection from the optimal downlink transmission beam. The processor is even further configured to execute the instructions of transmitting, to a node, the selected random access preamble via the PRACH resource and an uplink transmission beam of the uplink subframe.

Abstract: Beam management for the downlink can be based on user equipment (UE) measurement of downlink (DL) reference signal (RS) and UE reporting. An alternative approach that may reduce overall RS overhead and latency is BM for the downlink based on uplink (UL) RS. With this approach, the network measures UL RS transmissions on multiple beams and uses these measurements for managing beams for the DL. Disclosed herein are various problems and enhancements related to UL RS based DL BM, in particular beam failure detection and recovery.

Abstract: Wireless User Equipment, UE, and network apparatuses may be adapted to facilitate continuity of Multicast/Broadcast Service, MBS, across cells. A UE in idle/inactive mode, for example, may receive MBS assistance information comprising scheduling information defining MBS reception windows and perform a cell reselection evaluation process accordingly. An UE in connected mode may conduct and report MBS quality measurements and receive an RRC reconfiguration comprising an MBS configuration for a target cell, determine that MBS transmission progress differs between the source cell and the target cell, and recover lost MBS PDUs or delete duplicate MBS PDUs accordingly. A network apparatus, such as a gNB for example, may map a GPRS Tunneling Protocol Sequence Number of an MBS PDU, to a Packet Data Convergence Protocol Sequence Number in a target cell, and determine an MBS configuration for use by a UE requesting a handover accordingly.
