    摘要: A method of wireless communication includes partitioning coexistence tasks between short term policy setting tasks and policy implementing tasks, processing the short term policy setting tasks using a first set of computing resources, and processing the policy implementing tasks using a second set of computing resources. The first set may be software resources configured for slower execution of tasks and the second set may be hardware resources configured for just-in-time execution of tasks. The policy may determine a time after which a first radio event is not to be interrupted and granting or denying later events based on whether they would begin before or after the do-not-interrupt time. The do-not-interrupt time may be based on a weighted priority of the first radio event.

    摘要: Techniques for estimating the response of a communications channel. In an aspect, a channel autocorrelation matrix is derived based on, e.g., certain assumptions about the time delay profile, Doppler profile. An eigenvector decomposition is performed on the autocorrelation matrix, and a set of dominant eigenvectors is determined. A received pilot signal vector is projected onto a projection matrix derived from the dominant eigenvectors to generate a set of eigen-coefficients, which is then used to reconstruct an estimated channel vector. In an exemplary embodiment, the eigenvector-based approach is combined with a simplified minimum mean-square error based approach to generate an estimated channel vector when the received signal-to-noise ratio is below a threshold.

    摘要: In a multi-radio user equipment, a power backoff or similar restraint may be placed on communications of a first radio, such as LTE, in order to protect operations of a second radio, such as Bluetooth, depending on the time remaining for completion of the communications of the second radio. Such protected operations may include paging or inquiry operations. A power backoff may be applied to an LTE radio in order to protect completion of the paging or inquiry operations. The power backoff may be increased as the time to completion of the paging or inquiry operations approaches.

    摘要: In a communications system, transmitter power gain can be changed between symbols. A power gain change of a first part of a transmit chain is initiated a first time, whereas a power gain change of a second part of the transmit chain is initiated at a second time, such that the resulting power gain changes of the first and second parts both occur substantially within an inter-symbol time in a desired relationship to one another. In one example, the power gain change of the first part is initiated before the beginning of the inter-symbol time to account for expected serial bus latency between initiation and execution of the power gain change of the first part. The power gain change of the second part is initiated during the inter-symbol time such that overall power does not exceed an amount (for example, a maximum permitted under a communication standard).

    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: 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.
