Publication number: 20220278733Abstract: An integrated terrestrial/non-terrestrial network may allow for enhanced network coverage. However, there are control and management challenges associated with an integrated terrestrial/non-terrestrial network because the network and user equipments (UEs) are no longer confined to only using conventional cellular communication via terrestrial transmit-and-receive points (T-TRPs). One challenge is how to perform beam management. In some embodiments, methods and systems are disclosed in which an indication of angular direction (e.g. beam direction) is provided by the T-TRP. The indication of angular direction may be used by a UE for communicating with a non-terrestrial TRP (NT-TRP), e.g. using beamforming. However, the methods are not limited to integrated terrestrial/non-terrestrial networks or the involvement of NT-TRPs, but apply more generally to indicating angular direction for directional communication.Type: ApplicationFiled: May 19, 2022Publication date: September 1, 2022Applicant: HUAWEI TECHNOLOGIES CO., LTD.Inventors: AMAN JASSAL, AMINE MAAREF, JIANGLEI MA

Patent number: 11323223Abstract: Aspects of the present application use diversity of more than one TCI state, QCL assumption, precoder and/or SRI on the network side to enable multiple transmission beams in a transmission period having multiple transmission opportunities to provide robust beam transmission from the network side. An example of transmission opportunities in a transmission period may be OFDM symbols in a slot. Aspects of the present application use diversity of more than one TCI state, QCL assumption, precoder and/or SRI at the UE to enable the UE to transmit multiple transmission beams in a configured transmission period having multiple transmission opportunities to provide robust transmission from the UEs. When using multiple transmission beams, in the event that data transmitted on one beam cannot be decoded (e.g. due to beam blockage, poor radio conditions, etc.), data transmitted on other beams can still be decoded successfully.Type: GrantFiled: July 22, 2020Date of Patent: May 3, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Yongxia Lyu, Aman Jassal, Jianglei Ma
