摘要： The disclosure provides for determining whether an encoded multi-part message in a channel is intended for a user equipment (UE). The UE may receive a codeword that can be a component of the encoded multi-part message. The UE may also de-mask the received codeword based on an assigned identifier assigned to the UE to provide a data sequence. The UE may also damask the received codeword based on re-encoding the data sequence to provide a detected identifier. The UE can also compare the detected identifier to the assigned identifier. The UE can be determined to be the intended recipient of the encoded multi-part message when the detected identifier is equal to the assigned identifier. The disclosure also provides for jointly determining a mask and a data sequence that approximates the encoded multi-part message.

摘要： UEs are adapted to facilitate reconstruction of a segment of corrupted bits. According to one example, a UE can receive a control channel transmission such as a HS-SCCH transmission. The control channel transmission may include a plurality of information bits and a plurality of cyclic redundancy check (CRC) bits. The UE may further determine that a contiguous segment of the received information bits is corrupt. The UE may accordingly utilize the uncorrupted information bits and CRC bits to reconstruct the corrupt information bits. In some instances, the UE may utilize the uncorrupted bits to reconstruct the corrupt information bits using a new generator polynomial. In other instances, the UE may utilize the uncorrupted bits to reconstruct the corrupt information bits using the original generator polynomial.

摘要： One aspect provides a method. The method comprises receiving a signal comprising a sequence of encoded symbols, each corresponding to one of a plurality of possible states. For each symbol in the sequence, the method further comprises determining a set of state metrics, each representing a probability that the respective symbol corresponds to the plurality of states. The method further comprises decoding the signal by processing runs of recursions using runs of forward recursions, whereby a later state metric in the sequence is updated based on a preceding state metric, and runs of recursions using runs of reverse recursions, whereby a preceding state metric in the sequence is updated based on a later state metric. The method further comprises outputting the decoded signal to a device. The decoding comprises performing a plurality of repeated iterations over the sequence.

摘要： A method in a communication system, where a systematic code obtained by systematic encoding of information bits having dummy bits inserted and by deletion of the dummy bits from results of the systematic encoding is transmitted. On a receiving side, the deleted dummy bits are inserted into the received systematic code and then decoded. The method includes: deciding a size of dummy bits for insertion into information bits; segmenting the information bits into a number of code blocks when a bit size of the information bits is greater than a stipulated size; inserting dummy bits into each block of the segmented information bits in conformity with a dummy bit insertion pattern; performing systematic encoding of each block of the information bits into which the dummy bits are inserted, and deleting the dummy bits from the results of the systematic encoding to generate a systematic code.

摘要： Virtual limited buffer modification for rate matching. A reduced-size memory module is employed within a communication device to assist in storage of log-likelihood ratios (LLRs) employed in accordance with turbo decoding. This architecture is also applicable to other types of error correction code (ECC) besides turbo code as well. The memory size is selected to match the number of coded bits (e.g., including information bits and redundancy/parity bits) that is included within a transmission. The received signals may be various transmissions made in accordance with hybrid automatic repeat request (HARQ) transmissions. When the LLRs calculated from a first HARQ transmission is insufficient to decode, those LLRs are selectively stored in the memory module. When LLRs corresponding to a second HARQ transmission is received, LLRs corresponding to both the first HARQ transmission and the second HARQ transmission are passed from the memory module for joint use in decoding.

摘要： Techniques to increase the capacity of a W-CDMA wireless communications system. In an exemplary embodiment, early termination (400) of one or more transport channels on a W-CDMA wireless communications link is provided. In particular, early decoding (421, 423) is performed on slots as they are received over the air, and techniques are described for signaling (431, 432) acknowledgment messages (ACK's) for one or more transport channels correctly decoded to terminate the transmission of those transport channels. The techniques may be applied to the transmission of voice signals using the adaptive multi-rate (AMR) codec. Further exemplary embodiments describe aspects to reduce the transmission power and rate of power control commands sent over the air, as well as aspects for applying tail-biting convolutional codes (1015) in the system.

摘要： A method, apparatus and program. The method comprises: receiving a signal comprising a sequence of encoded symbols, each corresponding to one of a plurality of possible states; for each symbol in the sequence, determining a set of state metrics each representing a probability that the respective symbol corresponds to each of the plurality of states; and decoding the signal by processing runs of recursions, using runs of forward recursions and runs of reverse recursions. The decoding comprises performing a plurality of repeated iterations over the sequence, and for each iteration: dividing the sequence into a plurality of smaller windows, processing the windows using separate runs of recursions, and performing an associated warm-up run of recursions for each window. The decoding further comprises, for each repeated recursion: alternating the direction of the warm-up runs between forward and reverse with each successive iteration over the sequence, storing one of the sets of state metrics from each window, and initialising the warm-up run of each window using a corresponding stored set of state metrics from a previous iteration.
