    摘要: A frontend receiver of a user equipment (UE) is configured with multiple transform operations assigned to separate sets of cells. One set of cells includes the serving cell of the UE and at least one additional cell within a first offset range of the serving cell. Another set or sets of cells include additional interferer cells within another offset range of the serving cell. After tracking the common frequency/timing offsets of each set of cells the assigned transform operation for that set transforms the time domain samples into frequency domain symbols. The individual frequency/timing offsets for each cell within the set are then tracked.

    摘要: Techniques for transmitting UE-specific reference signals (UE-RSs) in a wireless network are described. In an aspect, a UE-RS may be transmitted in different manners depending on the number of layers used for data transmission. In one design, a cell may determine subcarriers for a UE-RS based on a frequency shift if data is transmitted on one layer and based on a predetermined set of subcarriers (with no frequency shift) if data is transmitted on multiple layers. In another aspect, a UE-RS may be transmitted on subcarriers determined based on a frequency shift for data transmission on multiple layers. In yet another aspect, a UE-RS may be transmitted from a plurality of cells to a UE for coordinated multi-point (CoMP). In yet another aspect, a UE-RS may be transmitted in a data section of a subframe including only the data section.

    摘要: Systems and methodologies are described that facilitate signaling Physical Hybrid Automatic Repeat Request (HARQ) Indicator Channel (PHICH) resource assignments in a wireless communication environment. At least a portion of a current PHICH resource assignment for a current Transmission Time Interval (TTI) and at least a portion of a subsequent PHICH resource assignment for a subsequent TTI can be encoded within a common encoded signal. Further, the common encoded signal can be sent to an access terminal during the current TTI. For instance, the common encoded signal can be transmitted via a Physical Broadcast Channel (PBCH). Alternatively, the common encoded signal can be sent through dedicated Radio Resource Control (RRC) signaling during handover. The access terminal can decode the common encoded signal received from the base station to identify the current PHICH resource assignment (or portion thereof) and the subsequent PHICH resource assignment (or portion thereof).

    摘要: Techniques for facilitating cell search by user equipments (UEs) in a wireless communication system are described. In an aspect, a primary synchronization code (PSC) sequence may be generated based on a Frank sequence and a constant amplitude sequence that is repeated multiple times. In another aspect, a set of PSC sequences may be generated based on complementary sequences having good aperiodic correlation properties and efficient implementations. In one design, PSC sequences A+B and B+A may be formed based on Golay complementary sequences A and B, there “+” denotes concatenation. In yet another aspect, a set of secondary synchronization code (SSC) sequences may be generated based on a set of base sequences and different modulation symbols of a modulation scheme. Each base sequence may be modulated by each of M possible modulation symbols for the modulation scheme to obtain M different SSC sequences.

    摘要: Techniques for transmitting beacon signals to assist user equipments (UEs) perform cell search and techniques for detecting for beacon signals are described. In an aspect, cells may be assigned beacon patterns defined based on orthogonal grouping of subcarriers. U subcarriers usable for beacon may be arranged into G orthogonal groups, with each group including S subcarriers. P=SG different beacon patterns may be defined based on the G groups of S subcarriers. In another aspect, the cells may transmit their beacon signals at configurable transmit power levels, which may be determined based on target beacon detection performance. In yet another aspect, a UE may perform overlapping DFTs in order to capture more received power when symbol timing at the UE is not aligned with symbol timing of cells being detected. In yet another aspect, the UE may perform beacon detection with maximal likelihood decoding.

    摘要: Systems and methodologies are described that facilitate detecting cell interference and/or loading by analyzing control data transmitted between devices communicating in the cell. Control data resources can be transmitted related to communication received over data channels, and the control data resources can comprise quality indicators related to the data as well as resource identifiers that specify a resource over the data channel related to the data. Multiple control data resources can be transmitted per communication specifying a beginning and ending resource identifier of related data channel resources. If this control data is decodable at a wireless device, the associated resources corresponding to the resource identifiers can be marked as interfered and/or avoided in subsequent communication or resource allocation requests by the wireless device.
