Title:
BEAM INDICATION METHODS IN WIRELESS COMMUNICATION SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2021/093179
Kind Code:
A1
Abstract:
Methods, systems, and devices for signaling beam indications in mobile communication technology are described. An example method for wireless communication includes transmitting, by a network node to a wireless device, in a current timeslot, a beam reference information in a message comprising information related to transmission parameters for receiving control channel information by the wireless device in a dedicated timeslot that is subsequent to the current timeslot, the beam reference information comprising a quasi colocation configuration or spatial relation configuration.
