摘要： A method of symbol combining and incremental redundancy for link adaptation and code space management was proposed. In order to reduce constraints on the Walsh codes allocation, MCS level change, as well as frame duration change for the initial transmission and re-transmissions, a “rate matching” stage is proposed between the Turbo encoder and block interleaver on the transmitter. In the initial transmission, the Turbo encoded symbols are interleaved with or without any puncturing or repeating (i.e. puncture/repeat factor is set to 1). The coded symbols are also stored in the memory for possible retransmissions. In the re-transmission, the transmitter first determines the number of Walsh codes available for this user and MCS level and frame duration according to the C/I feedback values from MS. The stored coded symbols are then punctured or repeated according to “rate matching factors”. On the receiver side, “rate matching factors” can be derived from the number of code channels, MCS level and frame duration of current re-transmissions and initial transmission. Then, de-puncturing/de-repeating is performed before coded symbol combining. A similar rate matching based IR/symbol combining scheme can be used to design different IR using different rate matching algorithms. It has low implementation complexity and is easily made backward compatible.

摘要： A method and apparatus are provided that uses the feedback information from an ARQ signal that is received to control the transmit diversity of a transmitter. The method provides for improved performance over some existing ARQ plus open loop transmit diversity schemes in terms of bit-error rate for a given Eb/No. Furthermore, the method does not require extra signaling used by closed loop TD schemes.

摘要： A Hybrid Automatic Retransmission Request (H-ARQ) technique is provided for Multi-Input Multi-Output (MIMO) systems. The technique changes the basis (V) upon retransmission, which helps reduce the error probability upon retransmission. This basis hopping technique provides for improved performance gain without significant increase in design complexity. In one embodiment, communication device (100) includes a receiver section (114) for receiving an acknowledgment (ACK) or a non-acknowledgment (NACK) signal in response to information transmitted by the transmitter section of the communication device. If a NACK is received, a new basis is selected from a set of basis stored in a basis set unit (110). The new basis that is selected is then used by a linear transformation unit (106) in the retransmission of the information.

摘要： Transmit diversity (TD) has become a common technique used in modern wireless communications systems to improve performance. TD uses multiple antennas (e.g., 110 and 111) at a transmitter (e.g., 105) to transmit multiple encoded datastreams and a single (or multiple) antenna (e.g., 116) at a receiver (e.g., 115) to receive the datastreams. Preferred embodiments of the present invention provide a general architecture (e.g., 705) that can support different TD schemes and even non-TD, simplifying receiver design and minimizing hardware usage.

摘要： A method is provided to decode data encoded by any block code in a manner that substantially improves the error correction capability of the block codes, and that is independent of the encoder. The structure associated with the method desirably allows the testing of those hypotheses that are known to exist, such that one can use the a priori knowledge of the possible set of hypotheses to only search from among them. The method of decoding data is both advantageous and desirable since knowing the subset of the code word space that is being utilized in essence allows the distance between the code words to be increased yielding significant decoding benefits.
摘要翻译： 提供了一种方法来解码由任何块码编码的数据，其方式使得块码的纠错能力大大提高，并且独立于编码器。 与该方法相关联的结构期望允许测试已知存在的那些假设，使得可以使用先验知识可能的假设集合来仅从其中搜索。 解码数据的方法是有利的和期望的，因为知道正在使用的码字空间的子集本质上允许增加码字之间的距离，从而产生显着的解码优点。
