  • Patent number: 9119212
    Abstract: Communication techniques enable efficient communication to an UE (User Equipment) that is subject to a dominant interference signal that is transmitted by a different base station. Disclosed interference cancellation techniques, both UE-centric and network-centric, are suitable to this situation. These techniques are particularly advantageous when undesirable or difficult to introduce changes in the physical (PHY) and medium access control (MAC) layers at the existing base stations. UE-centric framework refers to an approach largely implemented by UEs to include pico or femto cells. Network-centric framework closed-loop coordination between base stations and UEs mitigate interference thereby improving network performance.

  • Patent number: 8639996
    Abstract: Systems, methods, apparatus, devices and computer program products enhance uplink inter-cell interference cancellation with HARQ retransmissions. The decoding of a data packet depends on whether the interfering packet was decoded. Since the interfering packet is itself transmitted using a HARQ process, the transmission by the victim UT can be accomplished to take this situation into account. The latency of the victim UT can be varied based on the need for energy efficient transmission. In accordance with one specific aspect, if the receiver can decode multiple packets simultaneously, high data rates can be achieved using packet pipelining.

  • Patent number: 8611474
    Abstract: Methods of detecting a pulse sequence in a received signal are disclosed, each of which entails operating on samples of the received signal. One method entails determining a correlation of samples with a reference sequence, and detecting the pulse sequence based on the correlation. Another method entails selecting a reference sample associated with a pulse, and detecting the pulse sequence by analyzing samples based on one or more lengths of a time hopping interval and the reference sample. Another method entails selecting a reference sample associated with non-restricted time hopping intervals, and detecting the pulse sequence by analyzing samples that are based on substantially one or more lengths of a half pulse interval and the reference sample. Further, disclosed is a method of determining a timing drift by selecting samples, determining a time delay between the selected samples, and determining the timing drift based on the determined time delay and an expected time delay.

  • Publication number: 20110183607
    Abstract: An apparatus is disclosed having a receiver configured to communicate, by a first apparatus, with a second apparatus in a first mode; determine side information by the first apparatus based on the communication during the first mode; and store the side information by the first apparatus for communication in a second mode with the second apparatus, wherein the first and second modes of communication have different date rates. A method for wireless communications is also disclosed.
