Patent number: 11997641Abstract: A control information communication method, a base station, and user equipment are provided. A determination is made whether downlink control information (DCI) is used for multicast transmission or for paging. When the DCI is determined to be used for multicast transmission, the DCI is scrambled by using a single cell radio network temporary identifier (SC-RNTI). The DCI includes indication information and scheduling information, the indication information indicating whether a multicast control channel is updated. When the DCI is determined to be used for paging, the DCI is scrambled by using a paging radio network temporary identifier (P-RNTI). The scrambled DCI can be sent to user equipment by using a first downlink control information format.Type: GrantFiled: February 12, 2019Date of Patent: May 28, 2024Assignee: Huawei Technologies Co., Ltd.Inventors: Zheng Yu, Xiangsheng Guan, Li Chen, Xingqing Cheng

Patent number: 11208869Abstract: Provided is a packer plug. The packer plug, in this example, may include an engagement member having a no go feature configured to engage a no go shoulder of an associated packer assembly. The packer plug, in the example, further includes a nose cone having one or more nose cone openings coupled proximate a downhole end of the engagement member, and a check valve coupled proximate the engagement member. The check valve, engagement member, and nose cone, in this example, create a fluid path between a lower end and an upper end of the packer plug. Further to this example, the check valve is configured to allow downhole fluid to pass uphole through the fluid path as the packer plug is being pushed downhole, but substantially prevent uphole fluid from passing downhole through the fluid path as the packer plug is being pulled uphole.Type: GrantFiled: August 13, 2019Date of Patent: December 28, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Thomas Owen Roane, Antonio Rosas, Zheng Guan
