INTER-CELL BEAM MANAGEMENT CELL SWITCH: abstract simplified (18191666)

• This abstract for appeared for patent application number 18191666 Titled 'INTER-CELL BEAM MANAGEMENT CELL SWITCH'

Simplified Explanation

This abstract describes methods and apparatuses for facilitating serving cell changes in a wireless communications network. It focuses on beam management procedures, which involve the use of transmission configuration indicators (TCI) and cell switch commands. The user equipment (UE) mentioned in the abstract consists of a transceiver and a processor. The transceiver receives a TCI state identifier associated with a target serving cell and a cell switch command. In response to the cell switch command, the transceiver transmits a channel conveying a positive hybrid automatic repeat request acknowledgement (HARQ-ACK). The processor, on the other hand, performs a cell switch at a specific time, which is determined by a slot starting after a cell switch application time from the last symbol of the channel conveying the positive HARQ-ACK.

Original Abstract Submitted

Methods and apparatuses for methods and apparatuses for facilitating serving cell changes based on signaling related to beam management procedures in a wireless communications network. A user equipment (UE) comprises a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to receive a transmission configuration indicator (TCI) state identifier (ID) associated with a target serving cell, receive a cell switch command, and transmit, in response to reception of the cell switch command, a channel conveying a positive hybrid automatic repeat request acknowledgement (HARQ-ACK). The processor is configured to perform, based on the cell switch command, a cell switch at a time, wherein the time corresponds to a slot that starts after a cell switch application time from a last symbol of the channel conveying the positive HARQ-ACK.
