A method and apparatus for forming a resource block (RB) structure in a wireless communication system is provided. A user equipment (UE) receives a downlink (DL) signal via first physical resource blocks (PRBs), which are indexed by a network from a center of a band or from a center of a carrier, from the network. And, the UE transmits an uplink (UL) signal via second PRBs, which are aligned with the first PRBs according to synchronization signal (SS) blocks, to the network. Accordingly, a global PRB indexing and a local PRB indexing can be aligned with each other.

Methods on radio resource management (RRM) configurations and procedures in wireless communication are described herein. In particular, methods are described for providing a reference signal strength indicator (RSSI) measurement timing configuration (RMTC). In some embodiments, a UE may perform a RSSI measurement based on the RMTC on at least on downlink (DL) symbol outside of a synchronization signal (SS) block. Also described herein are methods for inter-frequency SSB measurement, and methods for RLM configurations and procedures. The methods on RRM and RLM configurations and procedures of the present invention can improve the user experience.

Bandwidth part (BWP) and discontinuous reception (DRX) are critical designs to help devices save power. Unlike DRX, a time-domain power-saving mechanism, the BWP is a frequency-domain mechanism newly proposed in the 3GPP NR system. The interaction between the two mechanisms needs investigation for performance optimization. Therefore, this work proposed a joint design for the BWP switching algorithm and analytical models. The simulation results showed that when the DRX cycle is 320 ms, and the packet arrival rate is 0.01/ms, our method improves 31.4% of packet delay or 19.5% of power consumption compared to the baselines. We also showed the range of the traffic arrival rate that a UE with both mechanisms configured is sensitive to the BWP switch strategy.

A physical resource block PRB grid indication method and a device are disclosed. The method includes: receiving, by a terminal device, location information sent by a network device, where the location information is used to indicate a relative location relationship between a first predetermined location in a synchronization signal block PRB grid and any PRB in a system common PRB grid with a first subcarrier spacing; and determining, by the terminal device, a second predetermined location of the any PRB based on the first predetermined location and the location information.

Utilizing wide bandwidth available in the millimeter wave channel is a promising candidate for the 5G and beyond 5G wireless sytems. To overcome severe channel degradation in millimeter wave channel, adopting massive MIMO with directional beamforming is essential, and base station and user should acquire best analog transmit/receive beam pair to establish a reliable link. The best analog transmit/receive beam pairs are found by maximizing a performance metric over the whole bandwidth. For efficient use of wideband in mmWave channel and to save energy at user, bandwith part (BWP) is adopted in NR which the user can be configured to use only a part of whole bandwith. With BWP, a user cannot use whole frequency information for best analog beam selection. In this paper, we have studied the impact of partial use of sub-carriers on the best analog transmit/receive beam selection.
