Abstract: Methods and systems are disclosed for a more flexible use of bandwidth parts (BWP) and cells for the various transmissions within the BFR procedure, such as the UL beam failure recovery request (BFRQ) and the DL beam failure recovery response (BFRR). The proposed framework allows these transmission to occur in BWPs with different Id, as well as on different cells. Example benefits include support for BFR on DL-only SCells by allowing the BFR UL transmissions on another cell with UL, support for sequential/parallel multi-cell BFRQ for improved BFR reliability and latency performance, and support for less UE-initiated BWP switching for BFR.

Abstract: Methods and apparatuses are described herein for Intra-UE Prioritization in uplink (UL) transmissions. In an example, an apparatus may receive first information indicating a first uplink grant associated with a first transmission and second information indicating a second uplink grant associated with a second transmission. The apparatus may determine, based on the first information and the second information, that the first transmission and the second transmission overlap at least partially in time. The apparatus may determine a first priority associated with the first transmission and a second priority associated with the second transmission. The apparatus may then cause, based at least in part on the first priority and the second priority, at least one of: prioritization of one transmission over another transmission, or preemption of the first transmission by the second transmission.

Abstract: Switching between Orthogonal Multiple Access (OMA) and Non-Orthogonal Multiple Access (NOMA) modes of a user equipment (UE) can be determined and indicated by a gNB to a UE at an RRC connected state using one or more of the following schemes: at an RRC (Radio Resource Control) layer with an RRC configuration message, at a MAC (Medium Access Control) layer with MAC CE (MAC control element) signaling, at a PHY (Physical) layer with DCI (Downlink Control Information) signaling, jointly with RRC configuration and DCI signaling, and/or jointly with RRC configuration and MAC CE signaling. The OMA or NOMA mode that the UE operates after the transition may be requested by the UE, indicated by the gNB, and/or may be based on one or more rules for OMA-NOMA switching.

Abstract: Methods, systems, and apparatuses are described herein for beamforming based initial access, beam management, and beam based mobility designs for NR systems. Issues are identified and addressed related to one or more of initial access, control channel design, eMBB and URLLC mixing, and beam training. The methods, systems and apparatus may include a receiving scheduling information and a preemption indication via a DCI. In addition, there may be a detecting and decoding of the preemption indication, a determining of a HARQ feedback associated, and a sending, to a network node, of the HARQ feedback.

Abstract: Radio resource management measurements for new radio unlicensed are performed that are based on a measurement model where a missed received signal transmission opportunity indicator is provided to higher layers to adapt the measurement functions performed by the radio resource control when a missed received signal transmission opportunity is detected. Radio link monitoring for new radio unlicensed is performed based on in-sync or out-of-sync indications that are based on the estimated radio link quality in combination with missed radio link monitoring reference signal transmission opportunities.
