Patent number: 11646817Abstract: A method of narrowband physical downlink control channel (NPDCCH) monitoring with early decoding and reduced monitoring is proposed.

Patent number: 11558822Abstract: Channel state information reference signal transmission can be used to estimate channel state information. Although resources needed for channel state information reference signals can be small, when multiple bandwidths are deployed within the same orthogonal frequency division multiplexing bandwidth, estimating the channel state information can comprise a channel state information reference signal resource grid for every bandwidth.

Power levels are determined comprising: a first power level for transmission of the first feedback via the first resource; and a second power level for transmission of the second feedback via the second resource. In response to a sum of the power levels being larger than an allowed transmission power, a configured transmission of the first feedback via the first resource is dropped. The dropping is based on a first priority of the first channel. The second feedback is transmitted via the second resource.Type: GrantFiled: July 13, 2021Date of Patent: January 3, 2023Assignee: Beijing Xiaomi Mobile Software Co., Ltd.Inventors: Alireza Babaei, Esmael Hejazi Dinan, Hua Zhou, Hyoungsuk Jeon, Kyungmin Park

Patent number: 11546859Abstract: Certain aspects of the present disclosure provide techniques for interference control for uplink transmission, for example, using multiple transmission configurations (e.g., antennas, beams, and/or antenna panels). A method that may be performed by a user equipment (UE) includes determining a transmit power for one or more uplink transmissions to a base station (BS) using one or more transmit power parameters. The one or more transmit power parameters are based, at least in part, on a transmission configuration of the one or more uplink transmissions. The method generally includes transmitting the one or more uplink transmissions to the BS using the determined transmit power.Type: GrantFiled: December 10, 2019Date of Patent: January 3, 2023Assignee: QUALCOMM IncorporatedInventors: Jung Ho Ryu, Tianyang Bai, Kiran Venugopal, Junyi Li
