摘要： Techniques for managing interference in a wireless communication system are disclosed. In one aspect, an estimated interference associated with data transmission over a plurality of subcarriers on an uplink is determined. The estimated interference may relate to intermodulation products associated with a parallel transmission over the plurality of subcarriers.

摘要： Techniques for adjusting transmit timing of base stations and user equipments (UEs) in a wireless network are described. In one operating scenario, a femto base station communicates with a femto UE, and a macro base station communicates with a macro UE located within the coverage of the femto base station. In an aspect, the transmit timing of the femto base station may be delayed relative to the transmit timing of the macro base station, e.g., to time align downlink signals from the femto and macro base stations at the femto and macro UEs. In another aspect, the transmit timing of the femto UE may be advanced relative to the transmit timing of femto base station by an amount larger than twice the propagation delay between the femto UE and the femto base station, e.g., to time align uplink signals from the femto and macro UEs at the femto base station.

摘要： Techniques for supporting data transmission based on a low-complexity transmission scheme are described. In one design, a first user equipment (UE) generates a first transmission for a single subcarrier assigned to the first UE. The first UE sends the first transmission on the single subcarrier concurrently with a SC-FDMA transmission sent on multiple subcarriers by a second UE. In one design, the first UE generates a continuous sinusoidal signal at a frequency corresponding to the single subcarrier. The first UE modulates the continuous sinusoidal signal with data symbols and reference symbols. In one design, the first transmission includes a cyclic prefix followed by a useful portion in each symbol period and has phase discontinuity at symbol boundary. A base station processes a received signal to recover the first transmission sent by the first UE and the SC-FDMA transmission sent by the second UE.

摘要： Techniques for supporting communication in an asynchronous TDD wireless network are described. In an aspect, downlink transmissions and uplink transmissions may be sent on different carriers in an asynchronous TDD wireless network to mitigate interference. In one design, a station (e.g., a base station or a UE) may send a first transmission on a first carrier in a first time period and may receive a second transmission on a second carrier in a second time period. The station may only transmit, or only receive, or neither in each time period. In one design, allocation of carriers for the downlink and uplink may be performed when strong interference is detected, e.g., by a base station or a UE. When strong interference is not detected, the first and second carriers may each be used for both the downlink and uplink.

摘要： Techniques for supporting communication for wireless devices in a wireless network are described. The wireless network may support a first physical channel having a first minimum SNR for reliable reception. Some wireless devices may require operation at a lower SNR. In an aspect, low SNR operation may be supported by transmitting data on a second physical channel that can be reliably received at a second minimum SNR that is lower than the first minimum SNR. In another aspect, low SNR operation may be supported by transmitting data on both the first and second physical channels. In yet another aspect, low SNR operation may be supported by transmitting data in multiple instances of the first and/or second physical channel. In yet another aspect, low power operation may be supported by transmitting the second physical channel in a portion of the system bandwidth instead of across the entire system bandwidth.

摘要： Techniques for sending a transmission in a manner to reduce peak-to-average power ratio (PAPR) of the transmission are described. A transmitter may select phases for a plurality of resource blocks based on a metric, e.g., PAPR. The transmitter may apply the selected phases to modulation symbols to be sent on the resource blocks. In one design, the transmitter may select one phase for each resource block and may apply the phase to all modulation symbols to be sent on the resource block. In another design, the transmitter may select multiple phases for multiple spatial layers in each resource block, one phase for each spatial layer. The transmitter may then apply each phase to all modulation symbols to be sent on one spatial layer in one resource block. For both designs, the transmitter may generate at least one OFDM symbol or at least one SC-FDMA symbol based on the modulation symbols after applying the selected phases.

摘要： Techniques for establishing and maintaining peer-to-peer (P2P) communication are described. In an aspect, P2P communication on an unlicensed spectrum may be established and maintained with network assistance. In one design, a user equipment (UE) may communicate with a wide area network (WAN) to establish P2P communication with at least one other UE on a first frequency band that is not licensed to the WAN. For example, the UE may receive an assignment of at least one frequency channel in the first frequency band for P2P communication. The UE may then communicate peer-to-peer with the other UE(s) on the at least one frequency channel. The UE may also communicate with the WAN to maintain P2P communication with the other UE(s), e.g., to switch to another frequency channel if necessary.

摘要： Systems, methods and apparatuses are provided that facilitate selecting resources, such as time slots, subframes, etc., for performing bandwidth switching related to activating and/or deactivating one or more carriers. A data portion of one or more subframes can be selected for performing bandwidth switching. In addition, a device can determine whether one or more downlink grants are received in the one or more subframes, and can avoid selecting such subframes. The device can alternatively perform the bandwidth switching and request retransmission of the data portion. Additionally or alternatively, the device can determine a type of the one or more subframes and/or signals transmitted in the one or more subframes to determine whether to perform bandwidth switching in the subframes. The bandwidth switching can include changing a sampling rate, reconfiguring frequency filters, modifying a local oscillator, etc.
