Abstract: Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.

Abstract: 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) 1xRTT (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.
