Determination of network synchronization

摘要

User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.

1. A method for wireless communications, said method comprising:
obtaining a synchronization indicator, at a user equipment (UE) located within a cell of a network, from a detected signal, wherein the synchronization indicator comprises information indicative of synchronization of the cell with respect to one of: a synchronous network or an asynchronous network; determining a synchronization status of the network in which said UE is located based on said synchronization indicator; and operating in one of: a synchronous mode of operation or an asynchronous mode of operation, in response to the determined synchronization status of the network.
