Patent number: 8341482Abstract: 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.Type: GrantFiled: December 5, 2011Date of Patent: December 25, 2012Assignee: Intel CorporationInventors: Stephen E.

Patent number: 8233501Abstract: 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.Type: GrantFiled: May 7, 2004Date of Patent: July 31, 2012Assignee: InterDigital Technology CorporationInventors: Stephen E.

Publication number: 20120189035Abstract: 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.Type: ApplicationFiled: April 3, 2012Publication date: July 26, 2012Applicant: INTERDIGITAL TECHNOLOGY CORPORATIONInventors: Nader Bolourchi, Leonid Kazakevich, Rui Yang

Patent number: 8116804Abstract: 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.Type: GrantFiled: March 7, 2011Date of Patent: February 14, 2012Assignee: InterDigital Technology CorporationInventors: Stephen G.
