摘要： Providing for modified rate-matching of modulated data to convey mobile network system information is described herein. By way of example, a rate-matching state, such as a data offset, can be introduced into a coded data stream that is modulated to resources of a wireless signal. The state can further be correlated to a state of the network system, such as transmit antenna configuration. Terminals receiving the wireless signal can analyze the signal to identify the rate-matching state and obtain the correlated network system state. Components of the terminal can then be configured according to the particular network system state, resulting in improving access point detection, and in some cases improved channel throughput and reliability.

摘要： Systems and methodologies are described herein that facilitate processing and pruning of blind decoding results (e.g., associated with grant signaling) within a wireless communication environment. As described herein, blind decoding results associated with grant signaling and/or other suitable signaling can be pruned in various manners, thereby reducing false alarm probabilities associated with such results. For example, techniques are provided herein for constraining respective decoding candidates to possible radio network temporary identifier (RNTI) values, performing validity checking on payload of respective decoding candidates, and selecting a most likely decoding candidate from a previously pruned set of candidates. Further, techniques are described herein for generating filler bits (e.g., padding bits, reserved bits, etc.) in a grant message according to a predefined pattern, thereby enabling checking of such bits to further reduce false alarm rates.

摘要： Reliability metric(s), based on output of a decoder module, associated with each possible hypothesis associated with blind decoding are provided that aids a pruning process by rejecting unreliable CRC-passed hypotheses. In an aspect, a downlink control channel carries scheduling assignments and other control information. As location, size, and CRC masking associated with downlink control information are not known to a receiver, blind decoding over possible hypotheses may be performed. The complex structure of the downlink control channel blind decoding results in increasing false alarm(s). Intelligent rules for pruning the decoding results are employed so that unreliable CRC-passed hypotheses are rejected as a function of respective reliability metric.
