Systems and methods are described for radio frequency (RF) calibration in a multiple antenna system (MAS) with multi-user (MU) transmissions (“MU-MAS”) exploiting uplink / downlink channel reciprocity. The RF calibration is used to compute open-loop downlink precoder based on uplink channel estimates, thereby avoiding feedback overhead for channel state information as in closed-loop schemes. For example, a MU-MAS of one embodiment comprises a wireless cellular network with one or multiple beacon stations, multiple client devices and multiple distributed antennas operating cooperatively via precoding methods to eliminate inter-client interference and increase network capacity.

The application discloses a method and device for estimating the adjustment effect of a handover parameter of a wireless cellular network. The application can realize accurate estimation of the KPI value after adjustment of the handover parameter by introducing causal information between the handover parameter and the KPI. In addition, the application can provide a basis for intelligent adjustment of the handover parameter, and improve network operation efficiency.

Embodiments of the present disclosure relate to techniques for gap-based feedback measurement in new radio wireless cellular networks. Embodiments of the present disclosure provide techniques for determining a synchronization signal (SS) / physical broadcast channel (PBCH) block (SSB)-based measurement timing configuration (SMTC) of measurement objects for which a user equipment is to measure its feedback information in one or more measurement gaps. Other embodiments are also described and claimed.

Systems, apparatuses, methods, and computer-readable media are provided to transmit multiple channel state information (CSI)-reference signal (RS) resources in different slots for non-Codebook based physical uplink shared channel (PUSCH) transmission in multi-transmission-reception point (TRP) operation. Other embodiments may be described and claimed.

Various embodiments herein provide techniques for a unified transmission configuration indicator (TCI) framework for multi-transmission-reception point (TRP) operation in a wireless cellular network. For example, embodiments may relate to use of a joint TCI codepoint to indicate one or more TCI states (e.g., a joint uplink (UL) / downlink (DL) TCI state, a UL TCI state, and / or a DL TCI state). The techniques may be used for multi-downlink control information (DCI) multi-TRP operation and / or single-DCI multi-TRP operation. Embodiments further relate to techniques for transmission repetition and uplink power control. Other embodiments may be described and claimed.
