Patent number: 11943065Abstract: In one configuration, multiple TRPs, or base stations such a next generation node B (gNB) base stations send different transport blocks (TBs) to a user equipment (UE) at the same time or at different times. In another configuration, multiple base stations may send the same data at the same time to a UE. When the same data is being sent by multiple base stations to a UE, the UE must be notified by some mechanism. Disclosed herein are multiple mechanism for notifying the UE that multiple base stations will be transmitting toe same data at the same time. When there is a backhaul between a TRP and another, each TRP can choose to send the same data stream to increase the reliability of the transmission when, for example, the UE receives at a low signal-to-noise ratio (SNR).Type: GrantFiled: May 3, 2021Date of Patent: March 26, 2024Assignee: ZTE CorporationInventors: Chuangxin Jiang, Zhaohua Lu, Yu Ngok Li, Shujuan Zhang, Zhen He, Huahua Xiao, Xinquan Ye, Rongchen Sun, Hao Wu
