摘要： Timing acquisition may be performed without typical correlation computations by determining a power of a received signal at certain points in time and using the determined power to identify gaps in the received signal. By determining gaps in the received signal, frame timing may be estimated, particularly in time-division networks where the location of guard periods within a frame is known. Gap detection may thus be used for timing acquisition.

摘要： In wireless communication systems, received signal estimation and detection is computationally intensive. During such processing, received signal matrices may be conditioned prior to inversion to improve stability. In particular, code domain conditioning, followed by time domain conditioning prior to inversion results in improved receiver performance. Such code and time domain conditioning may be particularly suited to a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system where code values are not averaged out of a received signal matrix.

摘要： Methods and apparatus are provided for operating in a first RAN at a working frequency, determining a priority of measurement tasks enabled by the first RAN, and dynamically scheduling the tasks according to the priority. For certain aspects, the first RAN may be a TD-SCDMA network. The measurement tasks are intended to measure at least one parameter of a serving cell in the first RAN on a primary frequency, at least one cell in the first RAN on at least one frequency other than the primary frequency, one or more cells in at least one RAN other than the first RAN (e.g., a GSM network) or any combination thereof. This dynamic assignment allows the UE to make scheduling decisions on which frequencies and RANs to measure, as well as how often these frequencies and RANs are measured, thereby providing for more efficient use of idle slots over conventional haphazard scheduling.

摘要： Enhanced frequency division multiple access (EFDMA) is a multiplexing scheme that sends modulation symbols in the time domain and achieves a lower PAPR than OFDM. An EFDMA symbol occupies multiple subband groups that are spaced apart in a frequency band, with each subband group containing multiple adjacent subbands. To generate an EFDMA symbol, multiple modulation symbols are mapped onto a first sequence of symbols. A transform (e.g., a DFT) is performed on the first sequence to obtain a second sequence of values. The values in the second sequence corresponding to the subbands used for the EFDMA symbol are retained, and the remaining values are zeroed out to obtain a third sequence of values. An inverse transform (e.g., an IDFT) is performed on the third sequence to obtain a fourth sequence of samples. A phase ramp may be applied on the fourth sequence, and a cyclic prefix is appended to form the EFDMA symbol.
摘要翻译：增强型频分多址（EFDMA）是在时域中发送调制符号并实现比OFDM更低的PAPR的复用方式。 EFDMA符号占据在频带中间隔开的多个子带组，每个子带组包含多个相邻子带。为了产生EFDMA符号，将多个调制符号映射到第一符号序列上。对第一序列执行变换（例如，DFT）以获得第二值序列。对应于用于EFDMA符号的子带的第二序列中的值被保留，并且剩余的值被清零以获得第三值序列。对第三序列执行逆变换（例如，IDFT）以获得第四序列。可以在第四序列上施加相位斜坡，并且附加循环前缀以形成EFDMA符号。
