摘要： A wireless communication terminal that has the self-interference due to the support of carrier aggregation, aggregating and jointly using two or more component carriers for transmission and reception, performs a first set of measurements on a received signal on a first operating frequency, wherein the first set of measurements are performed during which the wireless terminal transmits or receives signals on a second operating frequency. In an alternative embodiment, the wireless communication terminal changes the maximum transmit power limit on a first operating frequency on a per-slot basis to reduce the impact of harmonic or intermodulation distortion on a received signal at a second operating frequency.

摘要： A method and system for adaptive control of sub-carriers is useful for increasing frequency diversity gain to improve bit error rate performance in an Interleaved Frequency Division Multiple Access (IFDMA) system. The method includes selecting a combination of a Repetition Factor (RF) and a repetition block size (Q), from possible combinations of a RF and a Q, based on a number of users (Nu) (step 1405).

摘要： A multi-rate interleaved frequency division multiple access (IFDMA) modulation scheme permits users to transmit at different data rates or to vary their data rates while providing frequency diversity and preserving low peak-to-average power ratios and orthogonality between users at different data rates. The modulation scheme allows user-specific data block and repetition sizes, as well as user-specific modulation codes. Code assignment rules are provided for maintaining orthogonality between users having different data rates. Block and phase ramp modulation codes can be used. Asynchronous transmissions by users are supported by ensuring that the length of the cyclic extension is sufficiently long to tolerate worst case relative signal arrival delays between users and the channel pulse response duration over the communication medium. The modulation scheme can be employed in wireless communication systems, such as cellular or paging systems.
