    Abstract: A receiving device may identify a mutual information associated with a code block. The receiving device may identify whether the code block is decodable based on the mutual information. The receiving device may skip decoding the code block if the code block is identified as being not decodable. The receiving device may decode the code block if the code block is identified as being decodable. The code block may be identified as being not decodable if the mutual information is less than a second threshold. The code block may be identified as being decodable if the mutual information is greater than the second threshold. The receiving device may identify the second threshold based on an MCS associated with the code block or a code block length of the code block.

    Abstract: Methods, systems, and devices for wireless communication are described. For example, the described techniques provide for a wireless device transmitting an initial transmission associated with a data payload, such as a hybrid automatic repeat request (HARQ) payload. The initial transmission may include a set of bits modulated using a first bit ordering scheme, and the set of bits may include a first bit subset that are transmitted with a lower transmission reliability than a second bit subset of the set of bits. The wireless device may modulate the first bit subset using a second bit ordering scheme that differs from the first bit ordering scheme to generate a modulated bit set. The second bit ordering scheme may be associated with a higher transmission reliability for the first bit subset. The wireless device may transmit the second transmission for the data payload with the modulated bit set.

    Abstract: Mobile devices are used as temporary location anchor points, e.g., to supplement fixed location permanent location anchor points, in a wireless communications system in which mobile device locations are determined. A mobile device receives a command or request to operate as a location anchor point. In some embodiments, the command includes time information indicating the amount of time the mobile device is to operate as a location anchor point. In some embodiments, a mobile device operating as a location anchor point reports a received signal strength measurement along with information identifying the device from which the signal was received to a network element, e.g., a location server node. In some embodiments, a mobile device operating as a location anchor point broadcasts a signal providing location information. The mobile device receives compensation for operating as a location anchor point. Compensation may be monetary, services, or benefits provided by the network.

    Abstract: This disclosure provides methods, devices and systems for encoding data in wireless communications. Some implementations more specifically relate to performing a first encoding operation on data bits of a code block to shape the amplitudes of the resultant symbols such that the amplitudes have a non-uniform distribution. In some aspects, the probabilities associated with the respective amplitudes generally increase with decreasing amplitude. For example, the non-uniform distribution of the amplitudes of the symbols may be approximately Gaussian. In some aspects, the first encoding operation is or includes a prefix encoding operation having an effective coding rate greater than 0.94 but less than 1. The first encoding operation is followed by a second encoding operation that also adds redundancy but does not alter the data bits themselves. In some aspects, the second encoding operation is or includes a low-density parity-check (LDPC) encoding operation associated with a coding rate greater than 5/6.
