TERMINAL AND METHOD FOR HANDLING TIMING REFERENCE IN A WIRELESS NETWORK

摘要

According to a first aspect of embodiments herein, the object is achieved by a method in a terminal for handling a timing reference. The terminal is served by multiple serving cells of a wireless network, and is configured with a first Timing Advance, TA, group comprising the multiple serving cells, one of which, a current TR cell, acts as the timing reference for the multiple serving cells. When the current TR cell becomes unavailable for the terminal, the terminal autonomously selects a new TR cell to act as the timing reference for the multiple serving cells in the TA group.
