METHOD AND APPARATUS OF DYNAMIC BEAM INDICATION AND SWITCHING: abstract simplified (18190842)

• This abstract for appeared for patent application number 18190842 Titled 'METHOD AND APPARATUS OF DYNAMIC BEAM INDICATION AND SWITCHING'

Simplified Explanation

This abstract describes methods and devices used in a wireless communication system for dynamic beam indication and switching. The user equipment (UE) receives downlink control information (DCI) which includes a first field indicating a transmission configuration indication (TCI) codepoint. The UE also receives radio resource control (RRC) signaling which includes a parameter indicating whether a second field indicating a different TCI codepoint is present in the DCI. Based on this information, the UE identifies the presence or absence of the second field and determines a set of TCI states. The first field is a TCI field, and the second field utilizes bits from existing DCI fields.

Original Abstract Submitted

Methods and apparatuses for dynamic beam indication and switching in a wireless communication system. A method performed by a user equipment (UE) includes receiving, in downlink control information (DCI), at least a first DCI field to indicate a first transmission configuration indication (TCI) codepoint and receiving radio resource control (RRC) signaling including a first parameter indicating whether a second DCI field indicating a second TCI codepoint is present in the DCI. The method further includes identifying, based on the first parameter, a presence or absence of the second DCI field in the DCI and identifying, based on the first and second DCI fields, a set of a first TCI state and a second TCI state. The first DCI field is a TCI field, and the second DCI field uses one or more bits of one or more existing DCI fields in the DCI.
