    Abstract: Aspects describe utilizing a dedicated reference signal for supporting Network MIMO, distributed MIMO, Coordinated MultiPoint, and the like. A data modulation symbol is transmitting in the same direction as a pilot modulation symbol is transmitted. Two or more wireless devices can coordinate communications such that transmission of the same pilot modulation symbol and the same data modulation symbol are transmitted to a device in different directions, each direction associated with a wireless device and intended for a particular mobile device. Cluster-specific scrambling and/or user-group specific scrambling can be employed and a scrambling code can be communicated prior to transmission of the pilot modulation symbols and data modulation symbols.

  • Reliability metric for decoding hypothesis
    Patent number: 9405616
    Abstract: A reliability metric is used for determining whether to prune a decoding hypothesis. For example, a reliability metric can be generated for each possible hypothesis generated during blind decoding operations. The reliability metric can then be used in a pruning process whereby a determination to prune a given hypothesis is based on whether the corresponding reliability metric is above or below a reliability metric threshold. In some aspects, the reliability metric is based on the correlation between the symbols of a hypothesis and re-encoded symbols that are based on the hypothesis, whereby the correlation is normalized using an estimated power parameter that is independent of the hypothesis. Through the use of the reliability metric, decoding may be achieved with a low probability of false passes (in the case of noise) and a low probability of missed detection (in the case of a real signal).

  • Dynamic encryption keys for use with XTS encryption systems employing reduced-round ciphers
    Patent number: 9405919
    Abstract: One feature pertains to encrypting data to improve data confidentiality. In one aspect, a modified form of XTS encryption is provided for use with reduced-round block ciphers. A data unit index of data to be applied to the reduced-round cipher is encrypted under a secret key to generate or otherwise obtain a modified secret key for applying to the reduced-round cipher. That is, data to be encrypted by the reduced-round cipher is not encrypted under a static key but is instead encrypted under a dynamic key that varies according to the index of the data. If an attacker were to derive the value of the key applied to the reduced-round cipher by analyzing data encrypted by the cipher, the attacker would only obtain the dynamic key corresponding to one particular data unit index, rather than a global static key applied to an entire address space. Decryption procedures are also described.
