摘要： Techniques for addressing high interference observed by a receiver in a wireless communication system are disclosed. The receiver may observe different interference power levels across a transmission symbol. In an aspect, the receiver applies different weights to different portions of the transmission symbol to account for fluctuation of interference power across the transmission symbol. In another aspect, a transmitter may send a transmission symbol such that a receiver can ignore a portion of a symbol period with high interference. In one design, the transmitter generates a transmission symbol including at least two copies of a signal component. The transmitter transmits at least one copy of the signal component in a portion of the symbol period in which the receiver does not observe high interference. The receiver processes the at least one copy of the signal component to recover data sent in the transmission symbol.

摘要： Systems and methodologies are described that facilitate indicating a type of waveform utilized for uplink transmission in a wireless communication environment. An access terminal can select a type of waveform from a set of possible waveform types. Moreover, a reference signal can be generated based upon the selected type of waveform. For instance, a sequence employed to yield the reference signal can be generated and/or chosen as a function of the selected type of waveform. According to another illustration, a tone location and/or a symbol location of the reference signal can be based upon the selected type of waveform. Further, the reference signal can be sent as part of the uplink transmission to the base station from the access terminal. The base station can detect the selected type of waveform utilized by the access terminal for the uplink transmission based upon parameter(s) recognized from the reference signal.

摘要： Systems and methodologies are described that facilitate performing fast cell selection in a user device wherein the user device can select a serving sector from a list of sectors in its virtual active set (VAS), while in communication with a wireless network. The serving sector can be different from a nominal sector whose scrambling code the user device employs for transmission on the uplink, which scrambling code can be known to all sectors listed in the VAS for the user device. In this manner, all sectors in whose coverage area the user device is located can be included in the user device's VAS and can receive and demodulate transmissions there from.

摘要： Techniques for transmitting data from multiple transmit antennas using space orthogonal resource transmit diversity (SORTD) are described. For the SORTD scheme, a different orthogonal resource may be assigned to each transmit antenna. Data may be sent from the multiple transmit antennas using multiple orthogonal resources. In one design, a UE may process at least one information bit (e.g., with joint or independent coding) to obtain first and second sets of at least one modulation symbol. The UE may process the first set of modulation symbol(s) for transmission from the first transmit antenna using a first orthogonal resource. The UE may process the second set of modulation symbol(s) for transmission from the second transmit antenna using a second orthogonal resource. Each orthogonal resource may include a different reference signal sequence or a different set of reference signal sequence and orthogonal sequence.

摘要： A method for wireless communication is provided, at a half-duplex node operating in TDD mode and may be used with an eNB in an LTE system. The method comprises receiving a configuration of a first set of subframes for a first link communication containing at least one downlink subframe and at least one uplink subframe. A second set of subframes for a second link communication is then determined. This second set includes at least one backward compatible downlink hybrid automatic repeat request process and at least one backward compatible uplink hybrid automatic repeat request process utilizing a second set of subframes. Communication begins with a first set of nodes using the first link and the first set of subframes. A second set of nodes using the second link and the second set of subframes is also used for communication. Communication to a legacy node is also supported.
