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： 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： 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： Methods, systems, apparatus and computer program products are provided to facilitate the configuration and allocation of control information associated with transmissions of a wireless communication system. In systems that utilize multiple component carriers, cross-carrier signaling may be used to carry the control information associated with one component carrier on a different component carrier. By allowing control information messages to share their allocated search spaces, the number of decoding attempts needed to obtain control information can be kept within desirable limits while improving scheduling and resource allocation flexibility. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the disclosed subject matter. Therefore, it is to be understood that it should not be used to interpret or limit the scope or the meaning of the claims.

摘要： Techniques for transmitting and detecting for overhead channels and signals in a wireless network are described. In an aspect, a base station may blank (i.e., not transmit) at least one overhead transmission on certain resources in order to detect for the at least one overhead transmission of another base station. In one design, the base station may (i) send the overhead transmission(s) on a first subset of designated resources and (ii) blank the overhead transmission(s) on a second subset of the designated resources. The designated resources may be resources on which the overhead transmission(s) are sent by macro base stations. The base station may detect for the overhead transmission(s) from at least one other base station on the second subset of the designated resources. In another aspect, the base station may transmit the overhead transmission(s) on additional resources different from the designated resources.
