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： 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 wireless communication modifies an actual buffer status report value to create a modified buffer status report that is reported to a base station. The modified buffer status report value results in the base station sending fewer uplink grants to a user equipment. The fewer grants result in transmission gaps in a first radio access technology of the user equipment. The user equipment may use those transmission gaps in the first radio access technology to communicate using a second radio access technology.

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）以补偿在通信资源（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。

摘要： Radios (transceivers) in a multi- radio device (multi-mode device) may be represented by parameter nodes, each parameter node representing a communication configuration of a particular radio, i.e, a combination of radio resources that a transceiver may us, for instance, a particular frequency and a certain transmit power. A coexistence manager at the multi -radio device may determine compatible subsets of parameter nodes "compatible" means they may operate together without interference. The subsets represent communication configurations of the radios that are compatible for simultaneous operation which reduces interference. Compatible subset generation may occur during an evaluation phase of a coexistence manager of a multi -radio device. Compatible subsets are generated based on resolvability of radio events or other potential collisions of the subsets, such as by use of a progressive resolution (PR) graph, associated compatibility graphs, and instructions and logic corresponding to such graphs. A Bron-kerbosch algorithm of graphic theroy may be aplied therefore.

摘要： In user equipments (UEs) with multiple radios, interference between those radios may be reduced by monitoring radio performance and adjusting aggressor transmit power levels to ensure victim and aggressor performance stay within desired operational levels. Various factors may determine when a reduced power approach is desired. Such factors may include aggressor transmit power, received signal strength indicator, victim error rate, throughput loss, coverage impact, etc. Various methods of reducing transmit power may be used. For example, for Long Term Evolution communications, a power headroom report may be altered to adjust a modulation coding scheme and bandwidth allocated for a particular UE. For Bluetooth communications a power control mechanism may be overridden to ensure a device stays within a desired transmit power. A power reduction loop may be employed to monitor a device's transmit power.

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： 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.
