摘要： First incoming data comprising at least one OFDM symbol is received (302). A plurality of timing relationships is determined and each of the plurality of timing relationships relates to an alignment window of a fast Fourier transform (FFT) (304). Each of the plurality of timing relationships is applied to the first incoming data (306) and a plurality of achievable interference metrics associated with the first incoming data is responsively determined (308). Each of the plurality of achievable interference metrics is associated with a selected one of the plurality of timing relationships. The preferred interference metric is chosen from amongst the plurality of achievable interference metrics.

摘要： An interference contribution associated with a selected subcarrier of a plurality of subcarriers associated with a previously transmitted OFDM symbol or a current OFDM symbol is determined (300). A fast Fourier transform (FFT) output for the current OFDM symbol is also determined (304). The interference contribution is subtracted from the FFT output of the current OFDM symbol to form a modified FFT output (308).

摘要： A communication system having spreading code resources (11) (such as, for example, Walsh codes), and upon providing (12) an initial quantity of those spreading code resources to support a voice communication by a given mobile station, then determines (13) whether to alter that initial allocation during that voice communication. For example, when the voice communication for this mobile station does not actively comprise speech, a determination can be made to allocate a reduced allotment of the spreading code resources. The system then switches (14) the new allocation of spreading code resources for the initial allocation and the mobile station continues its voice communication using the new (increased or decreased) quantity of spreading code resources.

摘要： A base station communicates a positioning reference signal (PRS) to wireless communication devices over a downlink in a wireless communication system by encoding a PRS into a first set of transmission resources, encoding other information into a second set of transmission resources, multiplexing the two sets of resources into a subframe such that the first set of resources is multiplexed into at least a portion of a first set of orthogonal frequency division multiplexed (OFDM) symbols based on an identifier associated with the base station and the second set of resources is multiplexed into a second set of OFDM symbols. Upon receiving the subframe, a wireless communication device determines which set of transmission resources contains the PRS based on the identifier associated with the base station that transmitted the subframe and processes the set of resources containing the PRS to estimate timing (e.g., time of arrival) information.

摘要： The cell searcher module (CSM) of a wireless communication device detects that the device is in coverage region of an eNB by processing received signal associated with the primary synchronization (PSCH) and secondary synchronization (SSCH) sequences transmitted by the eNB. The wireless device determines whether candidate SCH signals from candidate neighbor cells are synchronous with SCH sequences from the serving cell by implementing one of three methods. In a first method, the CSM generates a joint estimate of the received power of SSCH sequences corresponding to already detected/identified serving cell and a hypothetical neighbor cell. In a second method, the CSM re-constructs SCH sequences corresponding to already detected cells and subtracts the re-constructed SCH sequences from the received signal to obtain a residual signal with reduced serving cell interference. In a third embodiment, the CSM performs a correlation of estimated channel responses to determine whether the neighbor cell is present.
摘要翻译：无线通信设备的小区搜索器模块（CSM）通过处理与eNB发送的主同步（PSCH）和次同步（SSCH）序列相关联的接收信号来检测设备在eNB的覆盖区域。无线设备通过实施三种方法之一来确定来自候选相邻小区的候选SCH信号是否与来自服务小区的SCH序列同步。在第一种方法中，CSM产生对应于已经检测/识别的服务小区和假想相邻小区的SSCH序列的接收功率的联合估计。在第二种方法中，CSM重新构建对应于已经检测到的小区的SCH序列，并从接收信号中减去重构的SCH序列，以获得具有减少的服务小区干扰的残留信号。在第三实施例中，CSM执行估计的信道响应的相关性，以确定相邻小区是否存在。
