    Abstract: One or more bits are used in peer discovery signals to signal a device's ability and/or willingness to participate in a cooperative manner with regard to one or more mobile device location determination related operations. In some embodiments, the one or more bits are located at predetermined locations within a header portion of a peer discovery signal. Different bits, in some embodiments, are associated with different specific cooperative location determination related operations. The peer discovery signal is transmitted, e.g., broadcast, periodically or on some predetermined basis by a mobile wireless communications device. In this manner, a device listening to the peer discovery signals can determine other devices' willingness to perform particular location discovery related operations with very little signaling overhead.

    Abstract translation: 在一个或多个移动设备位置确定相关操作中，在对等体发现信号中使用一个或多个比特来表示设备的能力和/或以协作方式参与的愿意。 在一些实施例中，一个或多个比特位于对等体发现信号的报头部分内的预定位置。 在一些实施例中，不同的位与不同的具体协作位置确定相关的操作相关联。 通过移动无线通信设备周期性地或在某些预定的基础上发送对等体发现信号，例如广播。 以这种方式，监听对等体发现信号的设备可以以非常少的信令开销来确定其他设备执行特定位置发现相关操作的意愿。

    Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for decoding low-density parity check (LDPC) codes, for example, using a parity check matrix having full row-orthogonality. An exemplary method for performing low-density parity-check (LDPC) decoding includes receiving soft bits associated to an LDPC codeword and performing LDPC decoding of the soft bits using a parity check matrix, wherein each row of the parity check matrix corresponds to a lifted parity check of a lifted LDPC code, at least two columns of the parity check matrix correspond to punctured variable nodes of the lifted LDPC code, and the parity check matrix has row orthogonality between each pair of consecutive rows that are below a row to which the at least two punctured variable nodes are both connected.

    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: Various aspects of the disclosure relate to encoding information and decoding information. In some aspects, the disclosure relates to an encoder and a decoder for Polar codes with HARQ. If a first transmission of the encoder fails, information bits associated with a lower quality channel may be retransmitted. At the decoder, the resulting decoded retransmitted bits may be used to decode the first transmission by substituting the retransmitted bits for the original corresponding (low quality channel) bits. In some aspects, to decode the first transmission, soft-combining is applied to the decoded retransmitted bits and the original corresponding (low quality channel) bits. In some aspects, CRC bits for a first transmission may be split between a first subset of bits and a second subset of bits. In this case, the second subset of bits and the associated CRC bits may be used for a second transmission (e.g., a retransmission).

    Abstract: Aspects of the disclosure relate to polar coding. A polar codeword may be generated by sorting a plurality of synthetic channels utilized for transmission of the polar codeword over an air interface in order of reliability utilizing a convex combination of the mutual information calculated for each synthetic channel based on an Additive White Gaussian Noise (AWGN) channel and the mutual information calculated for each synthetic channel based on a binary erasure channel. A polar codeword may further be generated by sorting the plurality of synthetic channels in order of reliability utilizing cumulative sums calculated for each synthetic channel. Each cumulative sum may be calculated from a binary representation of a position of the synthetic channel within the plurality of synthetic channels.
