    摘要： The present methods and apparatus relate to interference mitigation at a user equipment during wireless communication, comprising determining that a first portion of a first radio access technology (RAT) activity scheduled during a first time slot overlaps in duration with a second portion of a second RAT activity scheduled during a second time slot; excluding the first portion of the first RAT activity based at least in part on determining that the first portion of the first RAT activity overlaps in duration with the second portion of the second RAT activity; and performing a non-overlap portion of the first RAT activity during the first time slot， wherein the non-overlap portion of the first RAT activity is a portion of the first RAT activity that remains after excluding of the first portion of the first RAT activity.

    摘要： Method and apparatus for decoding code words received over a communication channel are disclosed. A radius-adaptive sphere decoding methodology reduces the number of operations in sphere-constrained search. Imposing probabilistic noise constraint on top of sphere constraint, particularly at an early stage, provides a more stringent necessary condition. Hence, many branches that are unlikely to be selected are removed in the early stage of sphere search. The trade-off between computational complexity and performance can be controlled by adjusting the pruning probability.

    摘要： Methods for improving the time to acquire an identity of a base station by a mobile station, by relying on locally-unique attributes of the base stations instead of globally-unique attributes of the base stations, are presented. In some embodiments, data may be requested, the data may contain a globally unique attribute of a base station, a first locally unique attribute of the base station, and a second locally unique attribute of the base station. In some embodiments, data may be received in response to the request, the data may contain at least the first locally unique attribute and the second locally unique attribute. It may then be determined that the data did not contain the globally unique attribute, and an identity of the base station based at least in part on the first locally unique attribute and the second locally unique attribute may be acquired.

    摘要： TDD devices may transmit using multiple antennas. First and second antennas having first and second receive conditions may receive a communication. In an aspect, first and second transmit conditions for the first and second antennas may be determined based on the first and second receive conditions. In an aspect, the first and second transmit conditions may be compared to select the first or second antenna for transmissions. In an aspect, the first and second receive conditions may be compared to select the first or second antenna for transmissions. In an aspect, first and second transmission conditioning values, which may determine transmission powers, may be determined based on the first and second receive conditions. A first transmission chain, associated with an active RAT or carrier, and a second transmission chain, associated with an inactive RAT or carrier, may be activated to send transmissions from the first and second antennas.
