Abstract: A user equipment comprises a transmitter and an adaptive modulation and coding controller. The transmitter is configured to transmit data over an air interface in a single transmission time interval with a first specified modulation and coding scheme, where the single transmission time interval has a plurality of transport block sets. In response to receiving a repeat request for retransmission of at least one particular transport block set, the transmitter retransmits the at least one of the particular transport block sets. The adaptive modulation and coding controller is configured to change the specified modulation and coding scheme to a second specified modulation and coding scheme, enabling a combining of a particular transport block set transmitted at the first specified modulation and coding scheme with a retransmitted version of the particular transport block set transmitted at the second specified modulation and coding scheme.

Abstract: A method for multicasting a packet begins by providing a buffer for each of two user equipments (UEs) in communication with a base station. A determination is made whether there is a previously unsent packet at the base station. A second determination is made whether both UE buffers are non-empty. A non-empty buffer is flushed if there is no previously unsent packet and if one of the buffers is non-empty. A packet is selected to be transmitted if there is a previously unsent packet or if both buffers are non-empty. The buffers are updated based on feedback received from the UEs.

Abstract: A method of transmitting data in a wireless communication system from a transmitter to a receiver, including the steps of modulating data at the transmitter using a first signal constellation pattern to obtain a first data symbol. The first data symbol is transmitted to the receiver using a first diversity branch. Further, the data is modulated at the transmitter using a second signal constellation pattern to obtain a second data symbol. Then, the second data symbol is transmitted to the receiver over a second diversity path. Finally, the received first and second data symbols are diversity combined at the receiver. A transmitter and a receiver are embodied to carry out the method above.

Abstract: A method and apparatus for retransmission processing in a communication receiver includes improving the performance of Incremental Redundancy (IR) combining and retransmission processing at minimal increased complexity. One aspect of these improvements involves the use of prior decoding results, if the decoding block quality is above a threshold value, rather than or in addition to prior demodulation results, in retransmission processing. That is, the teachings herein propose selectively using the hard bit decisions obtained from decoding previously transmitted data blocks, to improve the decoding of retransmitted data blocks.

Abstract: Systems and methods are provided for decoding signal vectors in multiple-input multiple-output (MIMO) systems, where the receiver has received one or more signal vectors from the same transmitted vector. The receiver combines the received vectors by vector concatenation The concatenated vector may then be decoded using, for example, maximum-likelihood decoding. In some embodiments, the combined signal vector is equalized before decoding.

Abstract: Regular data packets are scheduled for transmission from a sender to multiple receivers in a multicast ARQ system. In a joint scheduling and encoding procedure, a composite data packet is formed as a weighted linear combination of regular data packets. The corresponding coding weights are adapted based on feedback information from the receivers about received data packets such the composite packet represents a new linearly independent coding of regular data packets different from any multicast data packet previously received in a selected set of the receivers during the multicast session. A weight vector with at least two different non-zero coding weights adds a further degree of freedom and guarantees the ability to form a composite data packet that represents a new linearly independent coding for transmission.

Abstract: A decoding method for decoding information content in at least one data packet, which is transmitted from a sender to a receiver via a data link. The information is represented by a bit sequence, which is transformed into a transmittable redundancy version. The information is initially transmitted for a first time in a first data packet from the sender to the receiver. The information is represented by a first redundancy version, which is self-decodable. An incorrect receipt is confirmed by sending a confirmation from the receiver to the sender. The information is retransmitted at least a second time in a second data packet from the sender to the receiver upon receipt of the confirmation, wherein, for representation of the information, a second redundancy version is used, the selection of which is performed in dependence on a coding parameter, describing whether the redundancy version is self-decodable or not.
