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 serial coexistence interface between two radio devices is involved in arbitrating access to an antenna. The serial interface involves messages that are sent from one radio to the other radio. Serial messages communicated across the same conductor can communicate: 1) timing-precise antenna arbitration and control information, and 2) communication system state information. Examples of antenna arbitration timing-precise information include a request to use the antenna and a corresponding grant or no grant response. Communication system state information, on the other hand, is not involved in the carrying out of the mechanics of the packet-by-packet arbitration for the antenna, but rather is higher level system information usable to make higher level decisions about the arbitration strategy used. Communication system state information may include an indication of a button press, an indication of a user action, or a change in the operational mode of the higher level communication system.

Abstract: Systems and methodologies are described herein that facilitate prioritization and arbitration of radio events associated with a set of potentially conflicting radios supported by a wireless device. As described herein, bin-based priority can be implemented for respective radio events such that events are assigned to bins of varying priority levels based on factors such as functional correlations of respective events to data loss, event deadlines, or relative radio priorities. Subsequently, selection of an event combination can be performed based on bins to which respective events are assigned. Techniques are additionally described herein for arbitrating among conflicting radio events assigned to the same bin using random selection, history-based arbitration, or the like. As further described herein, arbitration can be adjusted to favor selection of new, ongoing, or previously events.

Abstract: Systems and methodologies are described herein that facilitate implementation and use of a sleep mode for a multi-radio coexistence manager. As described herein, respective radios coordinated by a coexistence manager (CxM) can be grouped into radio or sleep clusters, for which the CxM can enter a low-power mode (e.g., a sleep mode) based on respective operating states of radios in the clusters. As further described herein, a CxM can provide an acquisition sequence and/or other suitable means to enable respective radios to synchronize with the CxM. In addition, techniques are provided herein by which a CxM can indicate its present operating mode (e.g., active, wakeable sleep, non-wakeable sleep, or disabled) to respective radios, and by which a radio can wake the CxM from a sleep operating mode under predetermined circumstances.

Abstract: The present invention is a novel method and apparatus for a dual-mode radio (DMR) in a wireless communication system. The present invention allows Bluetooth™ protocol and 802.11 protocol devices to co-exist. The present inventive method classifies Bluetooth™ protocol and 802.11 protocol events according to importance. In the basic dual-mode radio method, the present invention assigns two levels of importance or priority Bluetooth™ events: “high” and “low”. In the enhanced dual-mode radio method, the present invention assigns three levels of importance or priority to Bluetooth™ events: “high”, “low” and “promotable”. The present inventive apparatus provides a means for disabling 802.11 transmissions when high-priority Bluetooth™ events are detected.

Abstract: A novel method and apparatus for implementing an overlay adaptive frequency-hopping kernel in a wireless communication system is described. The present inventive method and apparatus selects hopping frequencies based on channel conditions. Hopping frequencies are selected using an inventive overlay adaptive frequency-hopping (OAFH) kernel that maps bad channels to good channels while retaining the pseudo-random properties of the original frequency-hopping sequence. The OAFH kernel uses existing FH kernels to initially select hopping frequencies. If the initially selected hopping frequency has bad channel condition characteristics, the OAFH kernel maps the initially selected hopping frequency to a substitute hopping frequency having good channel condition characteristics.

Abstract: A frequency synthesizer device with a fast off-to-lock time to enable intermittent operation and achieve power savings through automatic control of its On/Off sequence. A relatively fast off-to-lock time is achieved by controlling the sequence of how various components of the synthesizer are reactivated. The voltage controlled oscillator is reactivated, at first operating at its previous operating frequency prior to being deactivated. The phase frequency detector is inhibited while its input signals, a reference signal and a feedback signal, are activated. In a channel hopping communication scheme, the phase frequency detector coarsely tunes the synthesizer to its previous operating frequency, and then jumps to its new operating frequency. Another aspect of the invention provides improved channel locking by guaranteeing that the phase of the feedback signal in a phase lock loop initially lags the phase of the reference frequency signal at the phase frequency detector.
