摘要： Techniques for supporting communication for different user equipments (UEs) on different system bandwidths are described. In one design, a base station transmits first control information to support communication for at least one first UE on a first system bandwidth and transmits second control information to support communication for at least one second UE on a second system bandwidth, which overlaps the first system bandwidth. The base station transmits data to the first and second UEs on the first and second system bandwidths, respectively. In one design, the base station receives third control information from the first UE(s) and fourth control information from the second UE(s) on a third system bandwidth. The base station receives data from the first UE(s) on the third system bandwidth and receives data from the second UE(s) on a fourth system bandwidth, which overlaps the third system bandwidth.

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.

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： 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 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 are provided for efficient allocation of frequency spectrum blocks. In one example, there is provided a method, operable by one or more network entities, for reallocating a portion of a first frequency band allocated to a first radio access technology (RAT) to a second RAT. The method may involve determining a migration block granularity for reallocating the portion of the first frequency band to the second RAT. The method may involve identifying spectrum block(s) of the determined granularity in the first frequency band. The method may involve aggregating the identified spectrum block(s) with a native carrier in a second frequency band allocated to the second RAT. The method may involve controlling of the aggregated spectrum block(s) via the native carrier for the second RAT.
