Methods and systems for inter-RAT handover in multi-mode mobile station

摘要

Described herein are aspects related to communicating with a first radio access technology (RAT) and a second RAT, wherein a set of multi-input, multi-output (MIMO) resources is allocated for communication between a mobile station (MS) and a base station (BS) of the first RAT. A request message is sent to the BS of the first RAT requesting reallocation of at least a portion of the set of MIMO resources in a scan duration. During the scan duration, signals are received from a BS of the second RAT over a reallocated subset of the set of MIMO resources and communications occur with the BS of the first RAT over a non-reallocated subset of the set of MIMO resources. During a normal duration subsequent to the scan duration, communications occur with the BS of the first RAT using the set of MIMO resources including at least some of the reallocated subset of the set of MIMO resources.

1. A method for communicating with a first radio access technology (RAT) and a second RAT, wherein a set of multi-input, multi-output (MIMO) resources is allocated for communication between a mobile station (MS) and a base station (BS) of the first RAT, the method comprising:
sending, to the BS of the first RAT, a request message requesting reallocation of at least a portion of the set of MIMO resources in a scan duration; during the scan duration, at least receiving signals from a BS of the second RAT over a reallocated subset of the set of MIMO resources and communicating with the BS of the first RAT over a non-reallocated subset of the set of MIMO resources; and during a normal duration subsequent to the scan duration, communicating with the BS of the first RAT using the set of MIMO resources including at least some of the reallocated subset of the set of MIMO resources.
