摘要： An adaptive thresholding technique eliminates suboptimum threshold values by adjusting for varying channel conditions to eliminate interference where no channel energy is present, without discarding viable taps having useful channel energy. The adaptive thresholding technique adaptively optimizes receive threshold values for both wide and local area channels based only on measured C/I ratios 300. Thresholds are calculated based on instantaneous C/I estimates and/or weighted average C/I estimates calculated from WID/LID energies obtained from the current superframe WIC/LIC symbols respectively. In alternate embodiments, thresholds are calculated based on instantaneous C/I estimates and/or weighted average C/I estimates calculated from WTPC and LTPC symbols for the wide and local area channels, respectively The present adaptive thresholding technique dynamically reduces the threshold as the C/I estimate increases to mitigate performance degradation due to removal of weak signal taps. There is a separate threshold for each of the 12 coding and modulation modes supported by an exemplary receiver.

摘要： 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. For instance, the data plane can evaluate a set of requested events, select event(s) to be executed, and provide responses to the associated transceivers relating to the selection(s).

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 method of wireless communication includes determining denial rates for first and second communication attempts of a packet using a first communication resource (e.g., an LTE radio). The method also includes allowing a second communication resource (e.g., a Bluetooth radio) to communicate when communication attempts from the first communication resource are denied. The denial rates are chosen to achieve threshold levels of performance for the first and second communication resources. The second denial rate may be set and the first denial rate adjusted in a looped manner to achieve desired Bluetooth performance. The denial rates may be set to deny all first communication attempts but to allow all second communication attempts. Final attempts to transmit Bluetooth packets may be given priority regardless of the first and second denial rates.

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.
