    摘要： Systems and methods for processing a physical random access channel are provided. In some embodiments, a method can include: receiving a signal indicative of a strong user and a desired user on a physical random access channel; performing at least one of a single segment frequency domain detection or a multi-segment frequency domain detection on the signal indicative of a strong user and a desired user; generating a residual signal by cancelling out the signal indicative of a strong user; and obtaining a message transmitted by a user equipment by performing at least one of the single segment frequency domain detection or multi-segment frequency domain detection on the residual signal.

    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.

    摘要： Techniques for supporting communication on multiple carriers are disclosed. In one design, a user equipment (UE) is configured with a base carrier and a dependent carrier linked to the base carrier. Data transmission on the dependent carrier is scheduled via a scheduling carrier, which is different from the dependent carrier. The UE receives a scheduling grant on the scheduling carrier and determines whether the scheduling grant is for the base carrier and/or the dependent carrier. The UE communicates (e.g., sends or receives data) on the base carrier and/or the dependent carrier based on the scheduling grant. The scheduling grant may be (i) a separate grant carrying scheduling information for only one carrier, (ii) a common grant carrying scheduling information for both carriers, (iii) a joint grant carrying separate scheduling information for each carrier, or (iv) a composite grant that may be a separate grant, a common grant, or a joint grant.
