摘要

A method includes: receiving one or more synchronization signals; deriving a synchronization reference from the one or more synchronization signals; receiving a plurality of reference signals; based on the derived synchronization reference, performing a plurality of measurements on the plurality of reference signals; based on the plurality of measurements, selecting a plurality of random access resources; and selecting a random access resource from the plurality of random access resources for transmitting a random access signal to at least one of the one or more TP's.

說明書

In some embodiments, if the device has obtained multiple random access configurations corresponding to multiple sets of allowed random access resources, the device may first select which of those sets to select from. For example, such a selection may be based on the measurement results corresponding to the different sync references, as described in the operation 106 of FIG. 1. In other embodiments, the network may decide based on which sync reference the device will perform random access. In LTE, for example, the UE may initially choose to which cell to perform random access, typically based on the measurement results. Then the UE would apply the random access configuration of that cell and select a corresponding resource. During handover, on the other hand, the serving cell decides to which cell the UE should perform random access.
