Abstract: A method of wireless communication includes adjusting a channel quality indicator (CQI) to compensate for coexistence interference experienced between communication resources (such as an LTE radio and a Bluetooth radio). The CQI may be set to zero, falsely indicating to a serving enhanced NodeB that a UE is out of range, thereby creating a gap in LTE operation that may be used by an alternate radio access technology. To compensate for fluctuating interference, the CQI may be adjusted to incorporate average coexistence interference over a period of time. Alternatively, the CQI at a time may incorporate coexistence interference regardless of whether interference is experienced at that specific time. A CQI value may also be boosted to compensate for a CQI backoff. CQI may be adjusted to avoid a spiral of death effect.

Abstract: Dynamic adjustment of antenna selection period at a wireless communication device or user equipment having two or more antennas. The described approaches consider an antenna selection performance metric. The antenna selection performance metric may include both measurement overhead (capacity loss due to measurements) and antenna switching capacity gain (gain in capacity through switching antenna subsets). The antenna selection performance metric may further include an estimate of UE speed or an antenna selection change rate. The antenna selection period may be adjusted by increasing or decreasing the antenna selection period based on the antenna selection performance metric. Antenna selection may be enabled or disabled based on the antenna selection performance metric.

Abstract: A method of wireless communication includes monitoring coexistence issues among supported radios in a User Equipment (UE). The method includes determining a coexistence policy for communication resource operation within a user equipment (UE) and configuring communication resources of the user equipment in accordance with the determined coexistence policy. The policy may give priority to an LTE modem, an ISM modem, or may implement a variable priority scheme. The policy may be communicated to each modem from a host over a software messaging communication line. Modems in the UE may communicate with each other through logical lines providing real time communication. The policy may determine the operation of each modem and the treatment of the logical lines by each modem.

Abstract: The present disclosure includes systems and methods for operating a wireless communication system in multiple modes. The system is configured in a first mode when a transmission interference in a receiver of a wireless device is below a first threshold. The system is configured in one or more intermediate modes when the transmission interference is above the first threshold and below a second threshold. The system is configured in a second mode when the transmission interference is above the second threshold. The one or more intermediate modes activate interference management processes and the wireless device transmits data and receives data simultaneously. In some embodiments, transmission interference may be based on an SINR measurement.

Abstract: Systems and methodologies are described herein that facilitate a centralized structure for managing multi-radio coexistence for a mobile device and/or other suitable device(s). As described herein, a control plane coexistence manager (CxM) entity and/or a data plane CxM entity can be implemented to directly interact with a set of associated transceivers (e.g., radios, etc.) in order to manage conflicts between events corresponding to the transceivers. Further, CxM operation can be divided between the control and data planes such that the control plane handles configuration and long-term operations such as radio registration, sleep mode management, long-term event resolution, interaction with upper layers, etc., while the data plane handles short-term operations with respect to radio event management based on incoming notifications or event requests.

Abstract: A method of wireless communication includes determining a frame offset between communications of a first communication resource (e.g., an LTE radio) and communications of a second communication resource (e.g., a Bluetooth or WLAN radio). The method also includes determining potential time slot configurations for the communications of the second communication resource. A time slot configuration is selected from the determined potential time slot configurations, to reduce degradation of the first communication resource due to conflicting time slots between the first communication resource and the second communication resource, based on the determined frame offset. The selection may be based on the determined frame offset.

Abstract: To mitigate potential interference between radio access technologies (RATs) on a multi-RAT device, traffic scheduling rules may be implemented so that communications of the individual RATs are timed in a manner that reduces interference. For example, communications of a Bluetooth/WLAN RAT may be scheduled such that initial and responsive communications of the Bluetooth/WLAN RAT occur during sub-frames of an LTE RAT that are less likely to cause cross-RAT interference.

Abstract: Interference between potentially conflicting radio access technologies (RATs) in a wireless device may be managed through a coexistence manager. The coexistence manager allows a first active RAT to yield conflicting resources to a second idle RAT for purposes of receiving signals to allow proper operation by the second RAT. These signals may be, for example, paging signals to a Long Term Evolution (LTE) radio or beacons to a wireless local area network (WLAN) radio.

Abstract: Systems and methodologies are described herein that facilitate a decentralized structure for managing multi-radio coexistence for a mobile device and/or other suitable device(s). As described herein, a coexistence manager (CxM) and/or other suitable means can be implemented in connection with a set of radios (or other transceivers) in order to manage conflicts between events corresponding to the radios. Functionality can be divided such that the CxM operates on the control plane and handles configuration and long-term operations such as registration, sleep mode management, interaction with upper layers, etc., while the respective radios operate on the data plane and handle short-term radio event management operations based on incoming notifications or event requests. For instance, radios can identify conflicts between requested external events and internally associated events and accordingly provide responses that allow or disallow the external events on an absolute basis or a conditional basis (e.g.

Abstract: Prior to implementing a coexistence solution for a multi-radio device, a measurement determines whether interference experienced by one radio is caused by another radio on the device. This determination includes comparing measurements of the first radio during times when the other radio is operational and when the other radio is inactive. If the compared performance measurements are within a certain range, a coexistence/interference management solution may be implemented.

Abstract: A multi-radio device, such as User Equipment (UE), may experience coexistence issues among various ones of its constituent radio devices that operate at the same time. Various aspects of the disclosure provide techniques to mitigate coexistence issues in multi-radio devices, where significant in-device coexistence problems can exist. In particular, a method for coexistence of multi-radio devices is described. The method includes identifying, at an upper layer of a multi-radio UE, a type of incoming broadcast stream data. The method further includes determining a coexistence policy for operation of communication resources within the multi-radio UE based on the type of the incoming broadcast stream data. The method also includes arbitrating, at a lower layer of the multi-radio UE, between the communication resources based on the coexistence policy.

The method generally includes scheduling a first antenna at the wireless device for communication using one of a first radio access technology (RAT) or a second RAT, scheduling one or more other antennas at the wireless device configured for communication using the first RAT, for communication using the second RAT in order to enable one of transmit or receive diversity on the second RAT or simultaneous communication on the first and second RATs, and transmitting an idle-mode indication to force he first RAT to an idle mode.

Abstract: A user equipment (UE) may detect a potential collision between a discontinuous reception (DRX) pattern of a first radio access technology (RAT) and a reception time of a message from a second RAT of a remote device. The reception time may be unknown. The UE may dynamically reconfigure the DRX pattern to reduce a likelihood of the potential collision. The UE may also configure transmission of a different message by the second RAT during a DRX off-period to reduce a likelihood of the potential collision.
