摘要： A method for load control in uplink interference cancellation systems with soft decision is disclosed. It is determined whether interference is to be cancelled from a received signal based on a packet size of the received signal. If the signal is to be cancelled, a maximal correlation factor between an interfering portion and a useful portion of the received signal is determined based on a transport block size of the received signal. If the signal is to be cancelled, a reduced target load for a base station is also determined based on the maximal correlation factor. If the signal is to be cancelled, uplink transmit power for one or more wireless communication devices is adjusted based on the reduced target load.

摘要： Techniques for reporting acknowledgement (ACK) information and channel quality indication (CQI) information in a wireless communication system are described. A user equipment (UE) may be able to receive data from up to two cells with dual-cell operation. The UE may determine CQI information for a first cell, determine CQI information for a second cell, and send the CQI information for both cells on a feedback channel with a single channelization code. The UE may process a control channel from each cell and, if control information is received from the cell, may further process a data channel from the cell to receive data sent to the UE. The UE may determine ACK information for each cell based on processing results for the data and control channels from that cell. The UE may send the ACK information for both cells on the feedback channel with the single channelization code.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which a single channelization code may be utilized on an uplink channel for providing a HARQ ACK/NACK response corresponding to DC-HSDPA+MIMO. Here, the set of channelization codes includes four codeword groups, each codeword group corresponding to a scenario wherein a node B schedules a single transport block or dual transport blocks on each of the two downlink carriers. Thereby, each of the four codeword groups may be designed to have an improved distance property in comparison to the utilization of a single codeword group for all HARQ ACK/NACK hypotheses, reducing errors.

摘要： Techniques for supporting UE operation with enhanced uplink are described. A UE may select a first signature from a first set of signatures available for random access for enhanced uplink, generate an access preamble based on the first signature, and send the access preamble for random access while operating in an inactive state. The UE may receive an acquisition indicator (AI) for the first signature on an acquisition indicator channel (AICH) from a Node B. The UE may use a default enhanced dedicated channel (E-DCH) resource configuration for the first signature if the AI has a first predetermined value. The UE may determine an E-DCH resource configuration allocated to the UE based on an extended acquisition indicator (EAI) and a second signature if the AI has a second predetermined value. In any case, the UE may send data to the Node B using the allocated E-DCH resource configuration.
