Patent number: 11758524Abstract: Methods, systems, and devices for wireless communications are described. A sidelink message may be scheduled for a UE during a first short transmission time interval (TTI). The first short TTI and a second short TTI for transmitting a sidelink feedback message corresponding to the sidelink message may both be shorter in duration than a another, longer type of TTI. The UE may transmit automatic gain control information in a first symbol period of the second TTI, transmit the sidelink feedback message in a second symbol period of the second TTI (after the first symbol period of the second TTI), and switch from operating in a transmitting mode to operating in a receiving mode during a third symbol period of the second TTI (after the second symbol period of the second TTI).Type: GrantFiled: August 26, 2021Date of Patent: September 12, 2023Assignee: QUALCOMM IncorporatedInventors: Chih-Hao Liu, Yisheng Xue, Jing Sun, Lik Hang Silas Fong, Xiaoxia Zhang

Patent number: 11757592Abstract: Aspects relate to techniques for signaling the capability of a wireless communication device (e.g., a UE) to support demodulation reference signal (DMRS) bundling for channel estimation across two or more slots in the sidelink or uplink. In some examples, a transmitting UE may transmit a DMRS bundling indication to a receiving device (e.g., a receiving UE for sidelink DMRS bundling or a base station for uplink DMRS bundling). The DMRS bundling indication may indicate a capability of the transmitting UE to support DMRS bundling. The transmitting UE may then transmit a respective set of DMRSs within each of two or more slots during a DMRS bundling window to the receiving device based on the transmitting wireless communication device and the receiving device supporting DMRS bundling.Type: GrantFiled: September 7, 2021Date of Patent: September 12, 2023Assignee: QUALCOMM IncorporatedInventors: Jung Ho Ryu, Sony Akkarakaran, Tao Luo, Junyi Li, Peter Gaal, Xiaojie Wang, Wooseok Nam, Juan Montojo, Xiaoxia Zhang, Jing Sun, Mahmoud Taherzadeh Boroujeni, Piyush Gupta, Hua Wang, Lik Hang Silas Fong, Tianyang Bai, Yan Zhou
