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 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: 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: 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: 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.
