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.

Abstract: Systems and methods are provided for a network to indicate beamforming information to user equipment (UE) for identification and measurement of reference signals. For example, a network may indicate whether all the reference signals are beamformed or not, or which reference signals are using the same transmission beamforming on the time domain, the frequency domain, or both time and frequency domains. In other embodiments, a network may indicate combining or averaging information to a UE.

Abstract: Techniques discussed herein can facilitate power ramping of PRACH (Physical Random Access Channel), for example, in connection with change of best gNB (next generation Node B) Tx (Transmit) beam and/or dynamic beam switching for control and/or data channels. Power ramping techniques discussed herein can comprise techniques for determining at least one of a power ramping counter or power offset for PRACH in connection with a change in best DL (Downlink) Tx (Transmit) beam. Dynamic beam switching techniques discussed herein can comprise employing DCI comprising at least one beam indication field indicating a beam index of a new beam of a BPL (Beam Pair Link) for at least one of a data channel or a control SS (Search Space).

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: A scrambling sequence generation method is disclosed for reference signals, data, and downlink and uplink control channels. The scrambling sequence generation method determines an initial seed value used to calculate the scrambling sequence. The initial seed value is based on different parameters relating to the to be transmitted signals, and some of these parameters are explicitly defined for New Radio.
