摘要： Techniques for generating reference signals in a wireless communication system are described. A set of Q reference signal sequences may be generated based on G pseudo-random sequences and L scrambling sequences, where Q=G·L, G>1 and L>1. The Q reference signal sequences may be used for Q cell identities (IDs), one reference signal sequence for each cell ID. In one design, a Node B may determine first and second indices based on a cell ID of a cell. The Node B may generate a pseudo-random sequence based on the first index, generate a scrambling sequence based on the second index, and generate a reference signal sequence based on the pseudo-random sequence and the scrambling sequence. The Node B may then generate a reference signal for the cell based on the reference signal sequence, e.g., by generating an OFDM symbol with the reference signal sequence mapped to a set of subcarriers.

摘要： Systems and methodologies are described that facilitate efficient cell acquisition in a wireless communication system. In one aspect, a reference signal for use in cell acquisition can be constructed in a bandwidth-agnostic manner such that it contains a common central portion in a predetermined frequency band that is independent of a bandwidth utilized by an associated wireless communication system. The central portion can be constructed as a two-dimensional block in time and frequency that spans a default cell search bandwidth, a predetermined bandwidth specified by synchronization codes or other signals, or another suitable bandwidth. A reference signal can then be constructed form the central portion by tiling or expanding the central portion such that it spans the entire system bandwidth.

摘要： When there are different power classes of base stations (BSs), there may be a need to coordinate transmission from the different BSs to reduce interference to a user equipment (UE) on both control channels and data channels. There are different ways of coordination. For some embodiments, time division multiplex (TDM) resource partitioning may be performed across BSs on a subframe level. TDM resource partitioning may avoid control channel interference since resource mapping on time and frequency for control channels may span the whole frequency domain. However, the data rate for the UE may be limited due to the TDM partitioning of subframes. In other words, a limitation may derive from control channel interference coordination. For some embodiments, a UE may transmit and/or receive in subframes other than the ones partitioned for the UE.
摘要翻译：当存在基站（BS）的不同功率等级时，可能需要协调来自不同BS的传输，以减少对控制信道和数据信道上的用户设备（UE）的干扰。有不同的协调方式。对于一些实施例，可以在子帧级别上跨越BS执行时分复用（TDM）资源划分。 TDM资源分配可以避免控制信道干扰，因为控制信道的时间和频率上的资源映射可能跨越整个频域。然而，由于子帧的TDM划分，UE的数据速率可能受到限制。换句话说，限制可以来自控制信道干扰协调。对于一些实施例，UE可以在除了为UE分配的子帧之外的子帧中发送和/或接收。

摘要： Techniques for supporting synchronization in wireless communication are described. A Node B generates a primary synchronization code (PSC) having a length of L chips based on a first inner sequence and a first outer sequence, where L is less than 256. The Node B also generates a sequence of secondary synchronization codes (SSCs) based on a second inner sequence and a second outer sequence, with each SSC having a length of L chips. L may be equal to 64, and the PSC and SSCs may have lengths of 64 chips. The Node B sends the PSC in each slot of each frame and sends the sequence of SSCs in each frame, one SSC in each slot. A user equipment (UE) detects for the PSC and then detects for the sequence of SSCs using slot timing from the PSC detection. The UE may perform PSC detection using correlation results for the SSCs.

摘要： Systems and methodologies are described that provide techniques for efficient cell search in a wireless communication system. In one aspect, a frequency reuse pattern can be generated by applying frequency shifts to reference signals transmitted from cells that provide coverage for a NodeB based on cell IDs or cell group IDs for the cells. The frequency shifts applied to reference signals can then be utilized as a basis for multiplexing reference signals from different cells using frequency division multiplexing (FDM) or a combination of FDM and other multiplexing techniques. Other adjustments to reference signals transmitted from respective cells, such as transmit power adjustments, can further be made to improve detection performance.
