摘要： Techniques for mitigating interference in a wireless communication system are described. In an aspect, a base station may periodically broadcast a load indication to convey information such as whether or not to use interference mitigation, which interference mitigation scheme to use, resources to apply interference mitigation, duration of interference mitigation, etc. Terminals may receive the load indication and perform interference mitigation as indicated by the load indication. In one design, a terminal may receive a load indication from a base station that the terminal desires to access. The terminal may determine whether to obtain reserved resources having reduced interference based on the load indication. In another design, a terminal may receive a load indication from a neighbor base station. The terminal may determine whether to reduce its transmit power or to request for resources prior to transmission based on the load indication.

摘要： Systems and methodologies are described that facilitate implementing a linear adaptive equalizer receiver on the downlink link of a UMTS TDD wireless communication system. A reference signal can be generated based on multiple non-common midamble sequences in a time slot of a received transmission. Traffic-to-pilot ratios for channel codes in the time slot can be generated, and relative strengths of channel codes associated with specific midambles can be determined to weight the midamble. A plurality of the weighted midambles can then be utilized to generate a reference signal to train the equalizer, which can facilitate utilization of total aggregate midamble energy rather than midamble energy associated with a single midamble in the signal.

摘要： Beacon symbols are sent periodically from the base stations in an OFDM system. The entire power of the base station, or a large portion of it is concentrated in these symbols, thus they are very easily recognized by the mobile stations. The frequencies upon which these symbols are transmitted and the time at which they are transmitted communicates information such as the base station/sector identity and the preferred carrier of the given base station/sector to the mobile station. In order to avoid collision between the beacon symbols of different base stations and sectors, the beacon symbols from different base stations/sectors are transmitted at different symbols times and on different subcarriers.
摘要翻译：信标符号在OFDM系统中从基站周期性地发送。基站的整个功率或其大部分集中在这些符号中，因此它们被移动台非常容易地识别。发送这些符号的频率和它们被发送的时间将诸如基站/扇区标识和给定基站/扇区的优选载波的信息传送给移动站。为了避免不同基站和扇区的信标符号之间的冲突，来自不同基站/扇区的信标符号在不同的符号时间和不同子载波上发送。

摘要： Systems and methodologies are described that facilitate increasing system capacity in a code-limited WCDMA (e.g., TDD, FDD, …) wireless communication environment. According to one aspect, a larger code space can be defined by introducing multiple code clusters within a sector, wherein each cluster has a unique scrambling code. Codes within a cluster can have orthogonal Walsh sequences that can be assigned to user devices to facilitate communicating over a wireless network and can overlap with codes in another cluster. The unique scrambling code assigned to each cluster can ensure that duplicate Walsh sequences in another cluster in the same sector appear as a pseudo-noise codes.

摘要： Systems and methods are described that facilitate improving paging signal strength at or near sector perimeters in a wireless network region by transmitted identical paging waveforms simultaneously from all sectors in the region and permitting over-the-air signal aggregation to combine signal energy near sector perimeters. Waveforms can be modulated using an orthogonal frequency division multiplexing technique and can be simultaneously transmitted according to predefined transmission resources over a multi-sector broadcast paging channel reserved for such identical waveforms. Cyclic prefix can be added to the identical waveforms to mitigate problems associated with delay spread and/or time-of-arrival differences at or near sector perimeters.

摘要： To transmit a multi-carrier signal, a transmitter provides zero symbols for guard subbands, performs OFDM modulation, and filters the resultant time-domain samples with a pulse shaping filter. To transmit a single-carrier signal, the transmitter partitions the single-carrier signal into segments. Each segment contains up to K samples and is padded, if needed, to the length of an OFDM symbol. Each padded segment is transformed from the time domain to the frequency domain to generate a corresponding frequency-domain segment with K symbols. For each frequency-domain segment, the symbols corresponding to the guard subbands are set to zero. Each frequency-domain segment is then transformed from the frequency domain to the time domain to generate a corresponding time-domain segment. A cyclic prefix may or may not be appended to each time-domain segment. Each time-domain segment is filtered with the same pulse shaping filter to generate an output waveform for the single-carrier signal.

摘要： Dynamic resource allocation systems, apparatus, and methods are disclosed for selectively improving the ability of a receiver to determine a channel estimate in an Orthogonal Frequency Division Multiple Access (OFDMA) system. A wireless communication system can use a common pilot channel configuration to aid channel estimation in one or more receivers in communication with the system. A receiver in communication with the system may be unable to demodulate received data due to an inaccurate channel estimate. The receiver can communicate to a transmitter in the system a request for additional channel estimation resources. The wireless communication system can provide additional channel estimation resources by inserting dedicated pilot channels into one or more of the frequencies allocated to symbols for the receiver. If the receiver is still unable to demodulate received data, the wireless communication system can incrementally insert additional pilot channels in the symbol associated with the receiver.
