METHOD TO IMPROVE CELL SELECTION FOR 5G

Document Type and Number:

WIPO Patent Application WO/2021/237440

Kind Code:

A1

Abstract:

In one aspect, a method for wireless communication by a user equipment (UE) in a network includes establishing a first connection to a first cell, wherein the UE is operating in Evolved Universal Terrestrial Radio Access (E-UTRA) New Radio (NR) dual connectivity (ENDC) mode. The method also includes determining a channel quality associated with the first cell based on one or more reference signals received from the first cell, and determining whether the channel quality is less than a threshold. The method includes determining whether a cell reselection condition is satisfied in response to the channel quality being less than the threshold. The method further includes establishing a second connection to a second cell in response to the cell reselection condition being satisfied, wherein the second cell is one of a Universal Mobile Telecommunications System (UMTS) cell or a Global Systems for Mobile (GSM) cell. Other aspects and features are also claimed and described.
