AI Technical Summary

Problems solved by technology

Increasing the number of small cells in the network will result in a significant increase in the number of measurements performed by mobile devices
Due to limited resources on the mobile device, the increase in measurements will result in decreased quality of service (QoS), poor mobile performance, etc.
Also, for some applications, when using existing WWAN radios, the performance of the network may be poor or not even available for communication

Embodiment Construction

[0027] In various embodiments, a second wireless unit (e.g., a wireless local area network (WLAN) wireless unit) of a mobile device may cooperate with a first wireless unit (e.g., a wireless wide area network (WWAN) wireless unit) to assist the WWAN wireless unit in performing WWAN operations (also referred to as applications). Specifically, the WWAN and WLAN radios of a mobile device may cooperate to assist the WWAN radio in various WWAN operations, including measurement, estimation, data acquisition, detection, and decoding of WWAN signals. WWAN operations may include: neighbor cell intra-frequency, inter-frequency, inter-RAT measurements; multiple Subscriber Identity Module (SIM) paging monitoring and paging / data processing; higher order diversity data acquisition and processing; interference avoidance, coordination and mitigation; System information detection and decoding; Reference Signal Time Difference (RSTD) measurements; Beacon detection for small cell identification;...

Abstract

A method of wireless communication includes communicating using a first radio based on a first radio technology; configuring a second radio based on a second radio technology different from the first radio technology to assist the first radio with a first-radio operation; and performing at least a portion of the first-radio operation at the second radio. The first-radio operation includes at least one of multiple subscriber identity module (SIM) page monitoring and page / data processing, higher order diversity data acquisition and processing, interference measurement and management, E-UTRAN cell global identifier (ECGI) determination and reporting, a reference signal time difference (RSTD) measurement, beacon detection for small cell identification, a minimization of drive test (MDT) measurement, and a speed estimation measurement. The first radio technology is a wireless wide area network (WWAN) technology and the second radio technology is a wireless local area network (WLAN) technology.
