Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for uplink (UL) beam selection in a New Radio (NR) network, the processing circuitry is to decode a medium access control (MAC) control element (CE) from a base station. The MAC CE identifies a sounding reference signal (SRS) resource set and a plurality of spatial relationship reference signals. An SRS is selected from the SRS resource set. A beam direction associated with a spatial relationship reference signal of the plurality of spatial relationship reference signals is derived. The spatial relationship reference signal corresponds to the selected SRS. The SRS is encoded for beamforming to transmit the selected SRS in the derived beam direction.

Abstract: The disclosure describes configuration schemes for secondary cell (SCell), bandwidth part (BWP) and physical resource block (PRB) indexing. An apparatus of user equipment (UE) for BWP activation and deactivation operation is disclosed. The apparatus includes baseband circuitry that includes a radio frequency (RF) interface, and one or more processors. The one or more processors are to receive radio resource control (RRC) data via the RF interface, configure a timer for a BWP according to the RRC data, and trigger the timer for the BWP in response to detection of an event associated with an access node after the BWP has been activated.

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for configuring and implementing secondary cell beam failure recovery procedures. For example, some embodiments are directed to a user equipment (UE) that includes radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to detect that a first beam associated with a secondary cell (SCell) is misaligned. The first beam is associated with a first reference signal (RS). The processor circuitry can further be configured to configure a beam failure recovery (BFR) procedure for the SCell and perform the BFR procedure to replace the first beam with a second beam, wherein the second beam is associated with the SCell.

Abstract: An approach is described for a source device associated with a source cell, where the source device includes radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry is configured to transmit configuration information to a user equipment (UE); transmit a request for a transmission or receiving time offset (TO) to the UE; receive the transmission or receiving TO from the EE. The processor circuitry is further configured to transmit the configuration information and the transmission or receiving TO to a second source device associated with a second source cell for a CLI reference signal measurement, wherein the EE is associated with the source cell, and the configuration information comprises an SRS instruction for the EE to enable an uplink (EE) CSI acquisition or tracking.

Abstract: Technology for a base station operable to encode a physical uplink control channel (PUCCH) resource indicator field length for transmission to a user equipment (UE) for enhanced Ultra Reliable Low Latency Communications (URLLC) (eURLLC) is disclosed. The gNB can determine the PUCCH resource indicator field length that indicates a length of a PUCCH resource indicator field, wherein the PUCCH resource indicator field length is related to transmission of a number of PUCCH symbols for eURLLC. The gNB can encode the PUCCH resource indicator field length for transmission in downlink control information (DCI) to the UE.
