Methods and apparatus to resolve paging monitoring conflicts in TD-SCDMA multimode terminal with MIMO

摘要

Certain aspects of the present disclosure propose techniques for resolving paging interval conflicts between two different radio access technology (RAT) paging intervals and for avoiding missing paging messages for a multimode terminal (MMT). Certain aspects provide a method for detecting messages associated with paging, by an MMT supporting multiple-input multiple-output (MIMO), from first and second networks using first and second RATs, such as Time Division Synchronous Code Division Multiple Access (TD-SCDMA) and Code Division Multiple Access (CDMA) IxRTT (Radio Transmission Technology), Evolution-Data Optimized (EVDO), or Wideband CDMA (WCDMA). The method generally includes using a first MIMO receive chain of the MMT to detect a first message associated with paging from the first network and simultaneously using a second MIMO receive chain of the MMT, different from the first receive chain, to detect a second message associated with paging from the second network.

1. A method for detecting messages associated with paging, by a multimode terminal (MMT) supporting multiple-input multiple-output (MIMO), from first and second networks using first and second radio access technologies (RATs), comprising:
using a first MIMO receive chain and a second MIMO receive chain for diversity reception on the first network; using the first MIMO receive chain of the MMT to detect a first message associated with paging from the first network; and simultaneously using the second MIMO receive chain of the MMT, different from the first MIMO receive chain, to detect a second message associated with paging from the second network in response to detecting an overlap between paging intervals of the first and second networks.
