Publication number: 20240129947Abstract: This disclosure provides systems, methods, and devices for wireless communication that support relaxed sensing for new radio (NR) sidelink over millimeter wave (mmW) operating frequencies. In a first aspect, a method by a user equipment (UE) of wireless communication includes identifying a resource selection trigger that indicates selection of one or more sidelink slots from a resource selection window. The UE may obtain long-term interference sensing statistics observed by the UE prior to the resource selection trigger. The UE can reduce a default sensing window length in accordance with the long-term interference sensing statistics and transmit a sidelink transmission in the selected sidelink slots. Other aspects and features are also claimed and described.Type: ApplicationFiled: September 12, 2023Publication date: April 18, 2024Inventors: Yisheng XUE, Xiaoxia ZHANG, Chih-Hao LIU, Jing SUN, Tao LUO

In aspects, a receiving user equipment (UE) may be configured to conduct combined reception/decoding of SCI repetitions (received from a transmitting UE over a sidelink) over multiple time-frequency slots at pre-defined occasions (e.g., occasions configured by a base station) to decode a sidelink transmission. In aspects, a receiving UE may receive from a transmitting UE over a sidelink, a sidelink transmission during a reception occasion that includes a plurality of reception opportunities for the receiving UE. Each reception opportunity of the plurality of reception opportunities includes a repetition of an SCI. The receiving UE decodes the SCI by combining the repetitions of the SCI received in one or more reception opportunities, and decodes a data transmission (e.g.Type: ApplicationFiled: December 18, 2023Publication date: April 11, 2024Inventors: Yisheng Xue, Jing Sun, Chih-Hao Liu, Xiaoxia Zhang, Tao Luo, Piyush Gupta

Patent number: 11930533Abstract: Channel occupancy time (COT) aware sensing and resource selection for new radio-unlicensed (NR-U) sidelink operations is disclosed. A first sidelink user equipment (UE) determines a sensing window or resource selection window (RSW) based on a projected listen-before-talk (LBT) completion time. The UE may sense for a subset of sideline resources within the RSW and COT-SI from a neighboring sidelink UE including identification of a COT initiated by the neighboring UE and one or more parameters associated with the COT. The UE may identify in-COT resources of located within the COT and out-of-COT resources located outside of the COT and then randomly select a set of transmission resources from the in-COT and out-of-COT resources. The UE may then transmit to a second UE using the set of transmission resources.Type: GrantFiled: September 12, 2022Date of Patent: March 12, 2024Assignee: QUALCOMM IncorporatedInventors: Chih-Hao Liu, Yisheng Xue, Jing Sun, Xiaoxia Zhang, Ozcan Ozturk, Tao Luo, Juan Montojo, Peter Gaal
