Patent number: 12273741Abstract: Methods and apparatus are provided for a UE to determine a UL spatial relation for an UL transmission in response to an unknown UL spatial relation switch. The UE may determine whether the UL spatial relation is based on an SRS transmission in UL, a CSI-RS in DL, or an SSB in the DL. If the UL spatial relation is based on the SRS transmission, the UE may select the UL spatial relation for the UL transmission corresponding to a Tx beam of the SRS transmission. If the UL spatial relation is based on the CSI-RS or the SSB, the UE may select the UL spatial relation for the UL transmission based on whether the unknown UL spatial relation switch is due to a corresponding resource for beam training not being configured by a communication network or a corresponding beam information being expired.Type: GrantFiled: December 15, 2020Date of Patent: April 8, 2025Assignee: APPLE INC.Inventors: Jie Cui, Yang Tang, Dawei Zhang, Hong He, Chunhai Yao, Chunxuan Ye, Haitong Sun, Weidong Yang, Wei Zeng, Yuchul Kim, Yushu Zhang, Zhibin Wu, Oghenekome Oteri

Patent number: 12267160Abstract: A user equipment wireless communication device in a wireless communication environment receives a signal from the network that includes a radio network temporary ID. From the radio network temporary ID, the user equipment is capable of determining whether a phase tracking reference signal is present based on the radio network temporary ID. If any of these are identified by the radio network temporary ID, then the user equipment determines that a phase tracking reference signal is present. After the user equipment has determined that the phase tracking reference signal is present, the user equipment can then determine which phase tracking reference signal antenna ports are to be used based on the values of the transmitted precoding matrix indicator value and the transmit rank indicator.Type: GrantFiled: January 8, 2020Date of Patent: April 1, 2025Assignee: Apple Inc.Inventors: Yushu Zhang, Gang Xiong, Yujian Zhang, Guotong Wang
