    Abstract: Apparatus and methods for selective decoding of received code blocks are disclosed. An example method includes receiving a code block, determining a code block quality indicator for the received code block, and attempting to decode the received code block if the code block quality indicator is greater than or equal to a threshold. If the code block quality indicator is less than the threshold, the received code block is discarded without decoding attempts. The threshold may be a static or dynamic threshold.

    Abstract: In an aspect, a method assists with blind decoding of uplink control signals on a Physical Uplink Shared Channel (PUSCH) and Physical Uplink Control Channel (PUCCH). The method assists in determining the uplink control path in the event a user equipment (UE) misses an uplink grant and blind decoding occurs. It is determined whether an uplink acknowledgement, rank indicator, and/or channel quality indicator are found on a PUSCH. If not, it is determined whether a scheduling request is expected and whether special handling for the scheduling request is indicated. Depending on those determinations, and whether any decoding attempts for uplink signals are successful, either the PUSCH or PUCCH is selected as the uplink control path.

    Abstract: Aspects relate to mitigating interference in a communication network that does not employ a centralized scheduler. A transmission sent on a subset of resources is evaluated to determine a number of communication pairs that have selected that subset of resources on which to transmit. If there are a large number of communication pairs transmitting on that subset, the transmission is ignored by a receiving device. The number of degrees of freedom that contain energy on the subset is evaluated to determine if an expected number of degrees of freedom that should have energy is met or exceeded. If the expected threshold number is met or exceed, the transmission is decoded by the receiving device, else the transmission is not decoded.

    Abstract: To perform erasure detection for an intermittently active transport channel with unknown format, a receiver determines an energy metric and a symbol error rate (SER) for a received block with CRC failure. The receiver computes uncorrelated random variables u and v for the received block based on the energy metric and SER, the estimated means and standard deviations of the energy metric and SER, and a correlation coefficient indicative of the correlation between the energy metric and SER. The receiver then evaluates the uncorrelated random variables u and v based on at least one decision criterion and declares the received block to be an erased block or a DTX block based on the result of the evaluation. The decision criterion may be defined based on a target probability of false alarm and adjusted based on another metric, such as a zero state bit, for the received block.
