  • Patent number: 10278189
    Abstract: In wireless communication systems, a determination may be made whether to hand off a user equipment (UE) based on whether the UE encounters time varying interference, such as UE to UE interference. The time varying interference may be present only in a specific set of time/frequency resources or subframes. Measurement reporting may be restricted to time/frequency resources which do not experience the time varying interference.

  • Patent number: 8612502
    Abstract: Systems and methodologies are described that facilitate equalization of received signals in a wireless communication environment. Multiple transmit and/or receive antennas and utilize MIMO technology to enhance performance. A single tile of transmitted data, including a set of modulation symbols, can be received at multiple receive antennas, resulting in multiple tiles of received modulation symbols. Corresponding modulation symbols from multiple received tiles can be processed as a function of channel and interference estimates to generate a single equalized modulation symbol. Typically, the equalization process is computationally expensive. However, the channels are highly correlated. This correlation is reflected in the channel estimates and can be utilized to reduce complex equalization operations. In particular, a subset of the equalizers can be generated based upon the equalizer function and the remainder can be generated using interpolation. In addition, the equalizer function itself can be simplified.

  • Patent number: 8457152
    Abstract: A MIMO communication system is adapted to encode multiple data streams at the same adaptable rate. Accordingly, the set of all possible modulation/rate combinations to all modulations with common rates is decreased thus resulting in the reduction of the number of possible packet formats carrying the data streams. Rate prediction is made more error-resilient, in part, due to the averaging over all information rates. Furthermore, the signaling overhead of the packets is reduced. Therefore, the tradeoff between the desired transmission rate granularity on the one hand, and robustness/signaling overhead on the other hand, is controlled by adjusting the coding rate.

  • Patent number: 8396438
    Abstract: Systems and methodologies are described that facilitate combining received signals from multiple receive antennas in a wireless communication environment. The received signals from the multiple receive antennas can be weighted utilizing an adaptive combination of maximal ratio combining (MRC) and interference nulling. The combination of MRC and interference nulling can be controlled based upon one or more configurable parameters. For instance, a covariance matrix can be modified to include the one or more configurable parameters, and the modified covariance matrix can be utilized in connection with interference nulling. Further, respective values for the one or more configurable parameters can be selected as a function of at least one input (e.g., measured interference-over-thermal (IoT) value, received loading level indicator, eigenvalue distribution of a covariance matrix, . . . ) related to noise correlation.

  • Patent number: 8335248
    Abstract: Systems and methodologies are described that facilitate equalization of received signals in a wireless communication environment. Using multiple transmit and/or receive antennas and MIMO technology, multiple data streams can be transmitted within a single tone. During equalization, receivers can separate data received within a tone into individual data streams. The equalization process generally is computationally expensive. Equalizer functions include the inverse operation, which can be computed using the fast square root method; however, the fast square root method involves large numbers of computations for a set of matrices, where the size of a matrix in the set of matrices increases with the number of transmit or receive antennas. Utilizing a modification of the fast square root method, a subset of the elements of the matrices can be selected and updated to reduce the number and/or complexity of computations.

  • Publication number: 20120155425
    Abstract: Techniques for transmitting pilot and for processing received pilot to obtain channel and interference estimates are described. A terminal may generate pilot symbols for a first cluster in a time frequency block based on a first sequence and may generate pilot symbols for a second cluster in the time frequency block based on a second sequence. The first and second sequences may include common elements arranged in different orders and may be considered as different versions of a single sequence. The terminal may transmit the pilot symbols in their respective clusters. A base station may obtain received pilot symbols from multiple clusters in the time frequency block. The base station may form each of multiple basis vectors with multiple versions of the sequence assigned to the terminal and may process the received pilot symbols with the multiple basis vectors to obtain a channel estimate for the terminal.

  • Patent number: 8189719
    Abstract: Techniques for sending and receiving signaling messages in a control segment are described. The control segment may be sent with CDM in multiple OFDM symbols. At a receiver, a received sequence is obtained for the control segment. A time-domain signaling sequence is generated based on a signaling message hypothesized to have been sent in the control segment. A correlating sequence is generated based on the signaling sequence. In one design, the signaling sequence is partitioned into multiple sub-sequences, one sub-sequence for each symbol period in which the control segment was sent. Each sub-sequence is cyclically shifted by an amount determined by a channel tap delay. The correlating sequence is then formed by concatenating all of the cyclically shifted sub-sequences. The correlating sequence may also be generated in other manners. The received sequence is correlated with the correlating sequence to determine whether the signaling message was sent in the control segment.
