  • Patent number: 8341482
    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.

  • Publication number: 20120307622
    Abstract: A medium access control-high speed (MAC-hs) comprises a hybrid automatic repeat request (H-ARQ) device configured to receive data blocks over a wideband-code division multiple access (W-CDMA) high speed-downlink shared channel (HS-DSCH). The H-ARQ device generates an acknowledgement (ACK) or negative acknowledgement (NACK) for each said data block received. Each received data block having a transmission sequence number. The H-ARQ device receives a new transmission instead of a pending retransmission at any time. At least one reordering device has an input configured to receive an output of the H-ARQ device and the at least one reordering device configured to reorder the received data blocks based on each received data block's transmission sequence number (TSN). Received data blocks are immediately forwarded for processing for higher layers when the received data blocks are received in sequence.

  • Patent number: 8233501
    Abstract: Data of a transport block set is to be transmitted in a wireless communication system. The wireless communication system uses adaptive modulation and coding and has a physical layer hybrid automatic repeat request mechanism. Segmentation information for potential segmentation of the transport block set is provided. The transport block set is transmitted with a first specified modulation and coding scheme. The transport bock set is received and whether the received transport block set is determined to meet a specified quality. When the specified quality is not met, a repeat request is transmitted. The first specified modulation and coding set is changed to a second specified modulation and coding set. In response to the repeat request, the transmit block set is segmented into a plurality of segments supported by the second specified modulation and coding set in accordance with the provided segmentation information. The segments are transmitted and at least two of the segments are transmitted separately.

  • Publication number: 20120189035
    Abstract: The number of users and data capacity of wireless systems are increased by employing apparatus and method for increasing the number of spreading codes available in the system by providing a mechanism to reuse the already allocated spreading code or use the codes that may correlate to those already being used within the same sector/cell. This, in return, provides capacity improvement proportional to the number of added base station (BS) antennas for each cell. An antenna null steering technique for code allocation maintains the cross correlation properties of the codes only for the desired user and to obtain a gain in capacity improvement.

  • Patent number: 8116804
    Abstract: A criterion for biasing a binary decision requiring an unequal protection which utilizes a measured signal to interference ratio (SIR). The SIR may be derived from a determination of channel estimation. The SIR is compared against a threshold, the threshold being selected to bias the decision toward a not acknowledge (NACK) as opposed to an acknowledge (ACK) determination. The technique is advantageous for providing biased binary decisions for high speed downlink packets (HSDP) but may be utilized for both uplink and downlink applications.

  • Patent number: 7831886
    Abstract: A stopping rule for Turbo decoding that is applied for both good and bad code blocks is disclosed. If the iteration either converges or diverges, decoding is terminated. In an alternative embodiment, the result of the stopping rule testing may be used for H-ARQ acknowledgement generation: if the iteration converges, an ACK is generated and if the iteration diverges, a NACK is generated. Optionally, the maximum number of decoding iterations may be dynamically selected based on MCS levels.
