Patent number: 11877245Abstract: Apparatuses, systems, and methods to indicate power transmission capability for a wireless device. A wireless device may connect to a base station (BS). The wireless device may transmit information regarding transmit power capability to the BS. The wireless device may indicate support for full power transmit capability for a subset of TPMIs for which it provides full power transmit capability, e.g., in a bitmap. This subset of TPMIs may be less than all of the available TPMIs (i.e., it may be a strict subset of the available TPMIs). Full power transmission capability of these indicated TPMIs may be provided via antenna switching and/or antenna virtualization. The wireless device may perform uplink transmission to the BS according to the transmit power capability indicated in the information. For example, the UE may transmit data using the antenna virtualization related to the subset of the TPMIs.Type: GrantFiled: November 28, 2019Date of Patent: January 16, 2024Assignee: Apple Inc.Inventors: Haitong Sun, Wei Zhang, Tianyan Pu, Pengkai Zhao, Jia Tang, Yushu Zhang, Yuchul Kim, Hong He, Dawei Zhang, Wei Zeng

Publication number: 20230413087Abstract: A device may wirelessly communicate with a number of different cells used in a carrier aggregation. The device may monitor physical downlink control channels (PDCCHs) on the different cells, dynamically switching between a dormant monitoring state (DS) and an active monitoring state (AS). In the DS, the UE may not monitor any PDCCH candidates on the active secondary SCells corresponding to the DS, or it may monitor PDCCH candidates in the search space (SS) set with the largest monitoring periodicity among the multiple SS sets on the active bandwidth part (BWP). In the AS, the UE may monitor a set of PDCCH candidates in physical resources configured by higher layers on the BWPs. Switching from one monitoring state to another may be facilitated through the use of a new downlink control information (DCI) format without data scheduling, a modified existing DCI format with data scheduling, and/or use of a DS timer.Type: ApplicationFiled: August 28, 2023Publication date: December 21, 2023Inventors: Hong He, Pengkai Zhao, Wei Zeng, Dawei Zhang, Haitong Sun, Yuchul Kim, Chunhai Yao, Yushu Zhang, Wei Zhang, Weidong Yang, Chunxuan Ye
