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: An apparatus is configured to be employed within a base station. The apparatus comprises baseband circuitry which includes a radio frequency (RF) interface and one or more processors. The one or more processors are configured to select one or more recovery channels based on one or more recovery factors; determine a beam recovery frame structure using the selected one or more recovery channels and based at least partially on beam correspondence capabilities; and provide the selected one or more recovery channels and the determined beam recovery frame structure to the RF interface for transmission to a user equipment (UE) device.

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: Provided herein are method and apparatus for beam recovery. An embodiment provides an apparatus for a user equipment (UE) including a radio frequency (RF) interface; and processing circuitry configured to: determine, in response to a beam failure, a channel for transmission of a beam failure recovery request as one of: a Physical Uplink Control Channel (PUCCH), a non-contention based Physical Random Access Channel (PRACH), and a contention based Physical Random Access Channel (PRACH); and encode the beam failure recovery request for transmission to an access node via the determined channel using the RF interface. At least some embodiments allow for transmission of a beam failure recovery request for beam recovery, allow for beam failure detection or new Tx beam identification, and allow for determining whether to configure a scheduling delay between a PDCCH and a PDSCH.

Abstract: Technology for a user equipment (UE) configured to perform beam failure recovery. The UE can encode a beam failure recovery (BFR) request for transmission on a physical random-access channel (PRACH) or a physical uplink control channel (PUCCH) to a next generation node B (gNB). The UE can monitor a dedicated physical downlink control channel (PDCCH) control resource set (CORESET) for a response from the gNB to the beam failure recovery request. The UE can select a default physical downlink shared channel (PDSCH) beam, wherein it is assumed, at the UE that a same quasi co-location (QCL) assumption for a PDSCH as a QCL assumption for the dedicated PDCCH CORESET; or a PDSCH demodulation reference signal (DMRS) is QCLed with a downlink (DL) reference signal (RS) of an identified candidate beam by the UE. The UE can decode a beam failure recovery request response from the gNB.

Abstract: Provided herein are method and apparatus for perform radio link monitoring (RLM) based on a Reference signal (RS). An embodiment provides a user Equipment (UE) comprising circuitry configured to: decode a Reference Signal (RS) received from an access node; and determine beam quality for one or more beam pair links (BPLs) of the RS between the UE and the access node based on the decoded RS, wherein each of the BPLs comprises a transmit (Tx) beam of the access node and a receive (Rx) beam of the UE. Also provided is a procedure of RLM. At least some embodiments allow for beam recovery request for UE beam refinement, and allow for determining whether radio link failure (RLF) occurs.
