Problems solved by technology

Unfortunately, such filter techniques do not adequately deny the use of adjacent bands and frequencies by multiple radio technologies and / or applications in wireless devices, therefore, such filter techniques do not adequately mitigate multiple radio technologies in wireless devices. Mutual interference generated by technologies and / or applications

Embodiment Construction

[0025] Figure 1A is a diagram of an exemplary communication system 100 in which one or more disclosed embodiments may be implemented. Communication system 100 may be a multiple access system that provides voice, data, video, messaging, broadcast, etc. content to multiple wireless users. The communication system 100 allows multiple wireless users to access such content by sharing system resources including wireless bandwidth. For example, the communication system 100 may use one or more channel access methods, such as Code Division Multiple Access (CDMA) CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), Single Carrier FDMA (SC-FDMA), etc.

[0026] Such as Figure 1A As shown, communication system 100 may include wireless transmit / receive units (WTRUs) 102a, 102b, 102c, 108d, radio access network (RAN) 104, core network 106, public switched telephone network (PSTN) 108, Internet 110, and other Network 112, however,...

Abstract

Methods and apparatus for mitigating in-device interference are described. The methods may include an in-device interference event (e.g. an interference situation), and the processing of events may depend on the priority of the technologies. A handover to another frequency or radio access technology (RAT) may occur in case a co-existing technology may be activated. The network may signal to the device a list of frequencies or RATs that it may be allowed to measure and handoff to. A network may provide a scaling value that the device may use to speed up reaction to the interference. The device may apply a scaling factor to an "out of synch' counter and / or the radio link failure (RLF) timer used for the RLF procedure. The device may apply different scaling factors for the measurements and time to trigger events. The device may trigger a report to the network requesting gaps for an alternate RAT.

Description

[0001] cross reference [0002] This application claims the benefit under 35 U.S.C.§.119(e) of U.S. Provisional Patent Applications Nos. 61 / 373,539, 61 / 389,030, 61 / 410,645, 61 / 430,704, 61 / 441,963, and 61 / 471,060, the The disclosure is incorporated herein by reference. Background technique [0003] Today, there are many wireless devices that support multiple radio technologies and / or applications. For example, existing wireless devices may include multiple components or devices including transceivers, transmitters or receivers. Such components can support different radio technologies and / or applications, including Long Term Evolution (LTE) technologies such as LTE and LTE-Advanced (LTE-A), wireless local area network (WLAN) technologies such as Bluetooth and WiFi in within Industrial Science and Medical (ISM) technology, and Global Positioning System (GPS) technology. [0004] While supporting multiple wireless technologies and applications increases the capabilities of wire...
