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.

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.

Abstract: Data of a time transmission interval is to be transmitted in a wireless communication system. The wireless communication system uses adaptive modulation and coding and has automatic repeat request mechanism. A transmission time interval has a plurality of transport block sets. The transport block sets are transmitted with a first specified modulation and coding scheme. Each transport block set is received and a determination is made as to whether the transport block sets meet a specified quality. When the specified quality is not met, a repeat request is transmitted. The specified modulation and coding scheme is changed to a second specified modulation and coding scheme that may support a reduced number of TBS's within the transmission time interval. In response to the repeat request, at least one of the transport block sets is retransmitted. The retransmitted transport block set is received. The retransmitted transport block set may be combined with a corresponding previously received transport block set.

Abstract: An ACK/NACK method and system for use in time division duplex (TDD) and frequency division duplex (FDD) systems. In high speed downlink packet access (HSDPA), based on the assignment of timeslots for the high speed shared information channel (HS-SICH), each user equipment (UE) can be assigned two (2) different channelization codes. It is then possible to adopt the signaling convention that one code represents acknowledge error-free (Ack) and the other code shall represent acknowledge error condition (Nack). The Node B is able to distinguish the presence of the transmitted channelization code as opposed to the channelization code which is not transmitted. The probability of error, using this invention is an order of a magnitude smaller than if the Ack/Nack were signaled using typical modulation techniques.

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 NACK as opposed to an 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.

Abstract: A system and method in a wireless communication network that efficiently determine when a message is intended for a particular wireless transmit/receive unit (WTRU). In accordance with the present invention, each WTRU is configured to receive communications on multiple communication channels. The WTRU receives and processes incoming signals on the multiple communication channels at the physical layer for an indication of which, if any, of the multiple communication channels is intended for the WTRU. If the indication is consistent with an expected indication for that mobile unit, the mobile unit accesses the particular communication channel and processes the information being sent therein.

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. The transmitted segments are received. The segmentation process may be applied more than once for a particular TBS transmission.

Abstract: A method for data related downlink signaling including selectively tailoring the UE ID to create a UE ID value, which is then added to a data field to create a data mask. This data mask is then further processed as the CRC field and transmitted with the data burst to provide CRC-related functions. An alternative embodiment discloses initializing a CRC generator with UE identification prior to CRC generation. This implicitly includes the UE ID within the CRC without requiring additional overhead signaling.
