Abstract:
A method for closed loop transmit diversity is disclosed. Data from user equipment (UE) that was transmitted using multiple transmit antennas is received. A new transmit antenna is selected for the UE. A new cycle period for the UE is determined. A new transmit antenna index and a testing indication based on the new cycle period are sent to the UE.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided in which a plurality of uplink carriers are utilized in a cellular communications system. In an aspect of the disclosure, a wireless terminal configured for use in a cellular network transmits an uplink with a plurality of uplink carriers including an anchor carrier and a secondary carrier, and receives a downlink with a plurality of downlink carriers. Here, the wireless terminal provides feedback information, such as a channel quality indicator and an acknowledgment, corresponding to the plurality of downlink carriers, on an uplink channel on each of respective carriers in a subset of the plurality of uplink carriers.
Abstract:
Systems and methods for effectuating a signal carrier configuration are disclosed. In one embodiment, the method comprises receiving an order, determining a signal carrier on which the order was received, determining a signal carrier configuration based at least in part on the order and the determined signal carrier, and changing the state of one or more signal carriers to effectuate the signal carrier configuration.
Abstract:
Systems and methods for packet acknowledgement are disclosed. In one embodiment, codewords are redundantly used in order to decrease the total number of bits required for feeding back acknowledgment information or in order to increase the Euclidean space between codewords.
Abstract:
Systems and methodologies are described that facilitate providing frequent secondary carrier measurement reports in multicarrier wireless communications. Secondary carrier measurement reports can be provided based on anchor carrier measurement reports. When an event or request to generate an anchor carrier measurement report is received, the anchor carrier measurement report can be generated along with a secondary carrier measurement report. In this regard, access points can receive the carrier measurement reports and determine mobility for a wireless device based on more than one carrier.
Abstract:
A cell identification method is provided. The method includes determining a reception state in a wireless device and comparing a reception cycle to a subframe parameter in the wireless device. The method also includes identifying a subsequent wireless cell within a predetermined time of the comparison.
Abstract:
A method for wireless communications is provided. The method includes generating at least one adjustable power parameter for an acquisition indicator channel (AICH) and generating at least one adjustable power parameter for an extended acquisition indicator channel (E-AICH). The method also includes generating at least one power offset representing differences between the AICH and the E-AICH.
Abstract:
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.
Abstract:
Systems and methodologies are described that facilitate providing uplink inter-cell interference cancellation. A radio network controller can receive measurement reports in order to identify non-serving nodes that are receiving interference from user equipment. Based on evaluation of such measurement reports, an interference message can be communicated to a Node B, wherein such measurement report can include information that allows the Node B to cancel or terminate the interference caused by such identified user equipment.
Abstract:
Scrambling/OVSF codes are varied with a TD-CDMA slot to overcome jamming effects by a dominant interferer. Interference is detected and a scambling code sequence is varied and employed to multiply a Walsh code assigned to a user device within a transmission time slot.
