Abstract: Methods and apparatuses for enhanced protection of data stored in a FLASH memory system involve a controller capable of adapting to the failure of one or more FLASH memory devices in the memory system. The controller stores data in the form of page stripes, each page stripe composed of data pages, and each data page stored in a different FLASH memory device. The controller also detects failure of a FLASH memory device in which a data page of a particular page stripe is stored, reconstructs the data page, and stores the reconstructed data page in a new page stripe, where the number of data pages in the new page stripe is less than the number of data pages in the particular page stripe, and where no page of the new page stripe is stored in a memory location within the failed FLASH memory device.

Abstract: Aspects of a method and system for a transmitting antenna selection failure recover mode are presented. Aspects of the system may include a transmitting mobile terminal that enables selection of a sequence of protocol data units (PDU), for example a sequence of sounding frames, which may be transmitted during an antenna selection procedure. During transmission of the selected PDU sequence, the transmitting mobile terminal may receive an antenna selection failure indication frame. The transmitting mobile terminal may enable retransmission of at least one previously transmitted PDU in the PDU sequence based on the failure indication. Transmission of subsequent PDUs in the PDU sequence may resume after the retransmission. Alternatively, upon receipt of the failure indication frame the transmitting mobile terminal may restart the selected frame sequence from the beginning, or may select a subsequent PDU frame sequence.

Abstract: Method and system for data-rate control by randomized bit-puncturing in communication systems. An encoder encodes at least one information bit thereby generating a group of encoded bits or an encoded frame. The encoder may be any type of encoder including a turbo encoder, an LDPC (Low Density Parity Check) encoder, a RS (Reed-Solomon) encoder, or other type of encoder. Any sub-portion of an encoded frame generated by such an encoder can be viewed as being a group of encoded bits. If the encoded frame is sub-divided into multiple groups of bits, each group can under processing in accordance with the means presented herein to effectuate rate matching. Based on a number of bits to be punctured from the group or frame generated by the encoder, a set of pointers and random-generated displacements is used to generate addresses for bits in the group or frame to be transmitted or punctured.
