Abstract: Aspects of the disclosure are directed to a method, apparatus, and computer software for wireless communication. In various examples, a method of wireless communication performed by a user equipment (UE) includes measuring channel quality over a measurement period associated with a voice call corresponding to a first subscription supported by the user equipment, determining whether the channel quality is sufficient to enable an adaptive multi-rate (AMR) decoder to ignore one or more bursts of a plurality of bursts carrying a block of data received at the user equipment, and causing the adaptive multi-rate decoder to decode the block of data without the one or more bursts when the channel quality is determined to be sufficient to enable the adaptive multi-rate decoder to ignore the one or more bursts. The channel quality may be measured by measuring a bit error rate for a transmission on a slow associated control channel (SACCH).

Abstract: Apparatus and methods enable rejection of adjacent channel interference (ACI) in a way that mitigates reductions in performance, such as increased bit error rates, which might otherwise occur with conventional filtering algorithms used to combat ACI. For example, a filter or a filter stage may be shifted in frequency by an amount that corresponds to a measured power of the ACI. In some examples, the amount to shift the filter may correspond to a carrier to interference (C/I) ratio, which itself is based in part on the ACI. In some examples, the amount to shift the filter may further depend on the noise power in the wireless channel, since a lesser shift of the filter frequency may be beneficial in noisy environments.

Abstract translation: 装置和方法能够以减轻性能降低的方式抑制相邻信道干扰（ACI），例如增加的比特错误率，否则可能会发生在用于防范ACI的常规过滤算法中。 例如，滤波器或滤波器级可以在频率上移动与ACI的测量功率对应的量。 在一些示例中，移位滤波器的量可以对应于本身部分地基于ACI的载波干扰（C / I）比。 在一些示例中，移动滤波器的量可进一步取决于无线信道中的噪声功率，因为​​滤波频率的较小偏移在噪声环境中可能是有益的。

Abstract: In some examples, a method and apparatus for wireless communication are disclosed. A wireless user equipment (UE) may receive an over-the-air tone pilot and apply the received pilot to a mixer. The mixer may mix the pilot with a local tone to generate a baseband signal. Here, the UE may determine an estimate of one or more parameters corresponding to a residual side band (RSB) in the baseband signal resulting from the mixer, and may accordingly apply the estimated one or more parameters to compensate for the RSB. The estimated RSB parameters may be refreshed online, by taking samples of the over-the-air tone pilot at a suitable refresh rate.
