    摘要： Methods and apparatus for noise estimation in a communication system. In an aspect, a method for noise and interference estimation is provided. The method includes identifying one or more unmodulated subcarriers in a received waveform, processing the one or more unmodulated subcarriers to produce a demodulated output, and determining a noise variance based on the demodulated output. In another aspect, an apparatus for providing a noise and interference estimation is provided. The apparatus includes selection logic configured to identify one or more unmodulated subcarriers in a received waveform, a processor configured to demodulate the one or more unmodulated subcarriers to produce a demodulated output, and variance determination logic configured to determine a noise variance based on the demodulated output.

    摘要： Systems and methods are provided for determining position location information in a wireless network. In one embodiment, timing offset information is communicated between multiple transmitters and one or more receivers. Such information enables accurate position or location determinations to be made that account for timing differences throughout the network. In another embodiment, transmitter phase adjustments are made that advance or delay transmissions from the transmitters to account for potential timing differences at receivers. In yet another embodiment, combinations of timing offset communications and/or transmitter phase adjustments can be employed in the wireless network to facilitate position location determinations.

    摘要： The present disclosure describes methods and apparatuses for improved transport block decoding in devices capable of wireless communication, which may include user equipment and network entities. For example, the present disclosure presents methods and apparatuses for decoding a code block from a plurality of code blocks corresponding to a transport block, obtaining a reliability indicator that identifies a reliability of the decoding of the code block, comparing the reliability indicator to a reliability threshold, and determining whether to decode a subsequent code block from the plurality of code blocks based on the comparing. Furthermore, these methods and apparatuses may include determining not to decode at least one subsequent code block of the transport block where the comparing indicates that the reliability indicator is less than the reliability threshold. As such, device power is not unnecessarily consumed by decoding likely superfluous code blocks.
