摘要： To improve performance in devices capable of communication using multiple radio access technologies (RATs), a gap pattern may be constructed in which a first RAT is quieted during certain times to allow for a second RAT to operate without interference. Gap patterns may be constructed based on timeline constraints, such as grant scheduling and HARQ performance, or based on desired performance levels of one or more of the RATs. Gap patterns may be selected by a user equipment or base station. Gap patterns may be selected to protect information in certain subframes. Potential gap patterns may be assigned weights indicating their desirability.

摘要： A method for mitigating the impact of a power imbalance on a remote data rate in a wireless local area network (WLAN) includes transmitting a wireless local area network (WLAN) acknowledgement (ACK) packet at a first transmit power level to a remote device. The method further includes transmitting, to the remote device, a WLAN data packet at a second transmit power level that is lower than the first transmit power level of the WLAN ACK packet. Another method for mitigating the impact of a power imbalance on a remote data rate in a wireless local area network (WLAN) may include selecting a wireless local area network (WLAN) acknowledgement (ACK) packet transmit rate independent from a rate at which a WLAN data packet is received. This method further includes transmitting, to a remote device, a WLAN ACK packet at the selected WLAN ACK packet transmit rate.

摘要： In a multi-radio device, a configurable filter may be placed on the transmit side of an aggressor radio to reduce interference to receive side performance of a victim radio. The filter may be adaptively configured based on performance of the victim radio. The configurable filter may be in the form of a notch filter. The depth and width of the notch filter may be configured. The filter may be used to create a virtual guard band between an Industrial Scientific and Medical (ISM) band and a cellular band by puncturing a physical uplink control channel (PUCCH) transmission nearest to the ISM band or reducing power on the nearest PUCCH transmission.

摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译： 一种无线通信方法包括调整信道质量指示符（CQI）以补偿通信资源（例如LTE无线电和蓝牙无线电）之间经历的共存干扰。 CQI可以被设置为零，向服务增强型节点B虚拟地指示UE超出范围，从而在可能由替代无线电接入技术使用的LTE操作中产生间隙。 为了补偿波动的干扰，可以调整CQI以在一段时间内并入平均共存干扰。 或者，无论在该特定时间是否经历干扰，一次的CQI可以并入共存干扰。 还可以提升CQI值以补偿CQI回退。 可以调整CQI以避免死亡效应的螺旋。
