摘要:
A method for Automatic Gain Control (AGC) in a receiver is performed by a circuit having an inner loop and an outer loop. The method includes performing an outer loop energy detection, mitigating interference using the outer loop energy detection, and performing a frequency domain energy measurement in the inner loop. The method also includes adjusting a digital gain component in the inner loop and an analog gain component in the outer loop in response to the frequency domain energy measurement.

Certain aspects of the present disclosure propose techniques for independently signaling features supported by a user equipment (UE) in different duplexing modes. The UE may be capable of communicating in frequency division duplexing (FDD) and time division duplexing (TDD) modes. The UE may obtain a FDD-specific feature group indicators (FGIs) set and a TDD-specific FGIs set, and signal at least one of the FDD-specific FGIs set or TDD-specific FGIs set. In addition, the UE may take one or more actions to reduce the likelihood of transitioning to a mode of operation that is different from its current mode of operation.

In a wireless communication system employing frequency division duplexing (FDD) that may be synchronous or asynchronous for transmitting data, in which the underlying Rx signals have different statistics, and where the hypothesis testing is degraded thereby, the improvement of generating a complementary searcher metric that is a noise metric (NM) comprising: projecting the Rx signals into the noise subspace of a pilot sequence.

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus updates a CIE in guaranteed non-MBSFN subframes. The apparatus refrains from updating at least one of an AGC, a TTL, an FTL, or an SNR estimation (FTL_SNR) in potential MBSFN subframes before a SIB is decoded to ascertain which subframes of a radio frame are MBSFN subframes and non-MBSFN subframes. The MBSFN subframes include a subset of the potential MBSFN subframes. The non-MBSFN subframes include a remaining subset of the potential MBSFN subframes and the guaranteed non-MBSFN subframes.

Techniques for windowing a transmission are disclosed herein. In one aspect of the disclosure, the length of a window used for windowing may be configurable and determined for a transmission based on a configuration of the transmission. The configuration of the transmission may be determined based on one or more parameters such as a system bandwidth, a bandwidth assigned for the transmission, the location of the assigned bandwidth within the system bandwidth, a modulation type used for the transmission, etc. In another aspect of the disclosure, a preferred length for a window may be determined for each of a number of possible configurations of a transmission. Different possible window lengths may be evaluated for each possible configuration based on one or more performance metrics. For each configuration, a window length that can provide the best performance for that configuration may be selected as a preferred window length for that configuration.
