Publication number: 20250096879Abstract: Various solutions for sensing beam management in integrated sensing and communications (ISAC) system are described. From the receiver's perspective, a sensing receiver may determine or receive a beam configuration and a reference signal (RS) configuration for a sensing of a target object. The sensing receiver may further perform sweeping(s) of receiving (Rx) beam(s) to receive RS(s) based on the beam configuration and the RS configuration. Then, the sensing receiver may perform the sensing of the target object based on the RSs. From the transmitter's perspective, a sensing transmitter may determine or transmit the beam configuration and the RS configuration for the sensing of the target object, and then perform sweeping(s) of transmitting (Tx) beam(s) to transmit the RS(s) based on the beam configuration and the RS configuration.Type: ApplicationFiled: August 29, 2024Publication date: March 20, 2025Inventors: Aimin Tang, Qimin Zhao, Wenze Qu

Patent number: 11646817Abstract: A method of narrowband physical downlink control channel (NPDCCH) monitoring with early decoding and reduced monitoring is proposed. Instead of blind decoding the NPDCCH at the end of each decoding instance, the UE tries to decode the NPDCCH at early decoding instances as well. The early decoding instances are determined based on the SNR of a received radio signal. Once NPDCCH is successfully decoded, UE stops the RF module. Furthermore, the UE skips some subframes for NPDCCH monitoring within each blind decoding interval, and turns on the RF only for synchronization and channel estimation purpose outside an NPDCCH monitoring length. The NPDCCH monitoring length is also determined based on the SNR of the received radio signal. By applying early decoding and reduced monitoring, UE power consumption can be reduced.Type: GrantFiled: October 17, 2017Date of Patent: May 9, 2023Assignee: MEDIATEK SINGAPORE PTE.

Publication number: 20220231883Abstract: Methods are proposed to derive measurement results for User Equipment (UE) antenna selection, beam selection, cell selection, handover, and radio resource management (RRM). First, UE determines its mobility state by using at least two of the following metrics: 1) Doppler information (e.g., from mobility detection gear, MD); 2) beam ping-pong rate, beam change rate, beam change per time period; and 3) moving speed and moving direction from an accelerometer sensor, rotation speed from a gyroscope, ambient magnetic field from a magnetic field sensor, and at least one active antenna set. Next, UE uses an averaging number that is adapted based on its mobility state to derive an average measurement result including at least one of RSRP, RSRQ, RSSI, IL, SNR, and SINR. Finally, UE performs antenna selection, beam selection, cell selection, or RRM based on the average measurement result and joint consideration.Type: ApplicationFiled: February 22, 2021Publication date: July 21, 2022Inventors: Kuan-Hung Chou, Wenze Qu
