Abstract: Some embodiments include systems, apparatuses, methods, and computer-readable media for use in a wireless network for determining a reception (Rx) beam sweep scale factor, N, that enables a user equipment (UE) to perform Rx beam refinement. Some embodiments are directed to a 5G Node B (gNB) that includes processor circuitry and radio front end circuitry. The processor circuitry can be configured to receive, using the radio front end circuitry, a MaxNumberRxB cam capability of the UE. The processor circuitry can determine based at least on the MaxNumberRxBeam capability of the UE and/or a Channel-State Information (CSI)-reference signal (RS) set with a repetition parameter configured to be ON, the value of N. The processor circuitry can generate a message comprising the value N, and encode the message for transmission to the UE, where N Rx beam sweeps enable the UE to perform Rx beam refinement.

The processor circuitry can be further configured to determine a measurement gap status of the LIE. Moreover, the processor circuitry can be further configured to prioritize between the SSB measurement signal and the uplink transmission signal based on the collision signal status and the measurement gap status. Additionally, the processor circuitry can be further configured to perform a wireless measurement according to the prioritization between the intra-frequency measurement signal and the uplink transmission signal.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for beam failure management, and in particular for beam management for high-speed train (HST) in Frequency Range 2 (FR2). According to embodiments of the present disclosure, a terminal device receives from a network device a configuration concerning a high-speed mode of the terminal device, the terminal device determines a reduced evaluation period for beam management in the high-speed mode based on the configuration. The reduced evaluation period determined by the terminal device is shorter than an evaluation period in a non-high-speed mode. Then, the terminal device performs the beam management using the reduced evaluation period.

Abstract: Systems and methods for determining a timing of a random access channel (RACH) occasion (RO) used to transmit a contention free random access (CFRA) preamble triggered by the receipt of a physical downlink control channel (PDCCH) order in a PDCCH are disclosed herein. A user equipment (UE) receives the PDCCH order and determines a timing offset value between the RO and a signal (e.g., a synchronization signal block (SSB), the PDCCH, a reference signal, etc.) to be used as a timing source. The UE also determines the arrival time of the signal to be used at the timing source. The UE then determines a time of the RO (during which the CFRA preamble will be transmitted) according to the arrival time and the timing offset value. Timing advance (TA) value(s) may also be accounted for as part of such a determination.
