摘要： Methods and apparatuses are provided that include a mobile station modem (MSM) embedded in a repeater for enhancing repeater functionality. The MSM can determine a timing of a base station based on one or more signals received therefrom. Using the timing, the repeater can align timing to that of the base station, determine cyclic prefix of the received signals, cancel echo from received signals, switch between receiving uplink and downlink signals, transmit PRSs according to the timing, and/or the like.

摘要： Systems and methodologies are described that enable serving cell selection in a wireless network with a multiple antenna repeater operable to support MIMO communications. In one example, a repeater using orthogonal frequency division multiplexing on the downlink can be equipped to receive, by one or more receive antennas, one or more signals using one or more radio frequency (RF) isolation schemes. The repeater can further be equipped to amplify and delay the one or more signals using one or more combination schemes. Moreover, the repeater can be equipped to transmit, by one or more transmit antennas, the amplified and delayed one or more signals, wherein at least one of the one or more receive antennas or the one or more transmit antennas includes two or more antennas.

摘要： Techniques for transmitting data using single-carrier frequency division multiple access (SC-FDMA) multiplexing schemes are described. In one aspect, data is sent on sets of adjacent subbands that are offset from one another to achieve frequency diversity. A terminal may be assigned a set of N adjacent subbands that is offset by less than N (e.g., N/2) subbands from another set of N adjacent subbands assigned to another terminal and would then observe interference on only subbands that overlap. In another aspect, a multi-carrier transmission symbol is generated with multi-carrier SC-FDMA. Multiple waveforms carrying modulation symbols in the time domain on multiple sets of subbands are generated. The multiple waveforms are pre-processed (e.g., cyclically delayed by different amounts) to obtain pre-processed waveforms, which are combined (e.g., added) to obtain a composite waveform. A cyclic prefix is appended to the composite waveform to generate the multi-carrier transmission symbol.
摘要翻译：描述了使用单载波频分多址（SC-FDMA）复用方案发送数据的技术。在一个方面，在彼此偏移的相邻子带的集合上发送数据以实现频率分集。可以向终端分配一组N个相邻子带，该组N个相邻子带从N个相邻子带的N个（例如，N / 2个）子带偏移，分配给另一个终端，然后将仅对重叠的子带观察到干扰。在另一方面，使用多载波SC-FDMA生成多载波传输符号。产生在多个子带组上的时域中承载调制符号的多个波形。多个波形被预处理（例如，循环地延迟不同的量）以获得预处理的波形，其被组合（例如，添加）以获得复合波形。循环前缀附加到复合波形以产生多载波传输符号。

摘要： Systems and methodologies are described that facilitate mitigation of interference through uplink scheduling in a wireless communication environment. Access points can assign multiple terminals to a single tile or segment of shared resource (e.g., a time frequency region) to maximize the number of terminals supported. However, combinations of certain types of terminals can cause a significant increase in interference. In particular, allocating multiple terminals having a relatively high velocity (e.g., terminals located in moving vehicles) to a single tile can cause an unacceptable increase in interference. To mitigate interference, high velocity terminals can be identified. Once identified, terminals can be allocated to the available tiles based at least in part upon avoiding combinations that result in a significant increase in interference.
