    Abstract: A mobile device estimates a data symbol from a received signal by using one or more interference cancellation algorithms. For one interference cancellation algorithm, the mobile device calculates (302) a Channel State Information (CSI) of an interfering sector and calculates (304) a CSI of a serving sector at a different time. The mobile device then determines (310) a correction factor to the CSI of the interfering sector by, for example, estimating a Doppler speed and a time difference between a first time interval like a preamble symbol and a second time interval like any symbol of interest in the data zone. Using the correction factor, the mobile device updates outdated interference information. The mobile device can cancel interference in the received signal distorted by co-channel interference by using the updated interference information. Also, the mobile device can be configured to combine results of multiple interference cancellation algorithms based on the applicability of the individual interference cancellation algorithms in particular scenarios.

    Abstract: A wireless communication device (200) including a first CRC coder that generates a first block of CRC parity bits on a transport block and associates the first block of CRC parity bits with the transport block, a segmenting entity that segments the transport blocks into multiple code blocks after associating, and a second coder that generates a second block of CRC parity bits on each code block and associates a second block of CRC parity bits with each code block. The first and second blocks of CRC parity bits are based on first and second generator polynomials. In one embodiment, the first and second generator polynomials are different. In another embodiment, the generator polynomials are the same and the transport block is interleaved before segmenting or the code block are interleaved before encoding with the second block of CRC parity bits.

    Abstract: The present disclosure describes a method and apparatus for transmit power calibration in a frequency division multiplexed wireless system (100). The method may include receiving (315) an uplink scheduling grant at a user equipment (120), establishing (320) a desired power level based on at least the uplink scheduling grant, and setting (325) hardware power settings based on the desired power level. The method may also include transmitting (330) data in a first subframe at a first power level based on the hardware power settings, measuring (335) the first power level in the first subframe, and determining (340) a difference between the desired power level and the measured first power level. The method may additionally include modifying (345) the hardware power settings based on the difference and transmitting (350) at a second power level based on the modified hardware power settings in a next transmission corresponding to the transmission in the first subframe.

    Abstract: A communication device is disclosed. The device is configured to generate a first block of first cyclic redundancy check (CRC) parity bits on a transport block wherein the first block of CRC parity bits is based on a first generator polynomial, to attach the first block of CRC parity bits to the transport block and to segment the transport block into multiple code blocks. The processor is also configured to generate a second block of CRC parity bits on each code block wherein the second block of CRC parity bits is based on a second generator polynomial that is different than the first generator polynomial. The first and second generator polynomials have a common degree. A second block of CRC parity bits is attached to each code block and the code blocks are concatenated after channel encoding.
