摘要： Systems and methods are provided for processing path components in a wireless communications network. A communications system is provided that includes one or more path analyzers to determine path magnitudes with respect to a set of channel paths employed in a wireless communications network. Such analysis can include analog or digital signal processing to determine such aspects as peak energy content, phase estimates, or other parameter of a signal path. From the path determinations, one or more threshold components select a subset of the channel paths for communications based in part on the path magnitudes.

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.

摘要： A closed-loop reverse-link power control algorithm for a frequency hopping orthogonal frequency division multiple access (FH-OFDMA) system is described. The power control algorithm adjusts the user's transmit power based on effective carrier-to-interference (C/I) and Received-Power-Over-Thermal (RpOT) measurements. The algorithm is inherently stable and is effective for FH-OFDMA systems with retransmissions.

摘要： A forward link (FL) RLP and a reverse link (RL) RLP that are different in design are used for data transmission on the forward and reverse links, respectively. The asymmetric RLP designs may be quantified by, e.g., different feedback mechanisms and/or different data transmission mechanisms used for these RLPs. The FL RLP may utilize a negative acknowledgment (NAK)-based feedback mechanism whereas the RL RLP may utilize an acknowledgment (ACK)-based feedback mechanism. The NAK-based FL RLP may transmit each RLP frame once in sequential order and retransmit RLP frames out of sequence when not received correctly. The ACK-based RL RLP may transmit RLP frames in sequential order, one frame at a time until the frame is received correctly or the maximum number of transmissions have been attempted. Timers with adaptive values computed based on actual traffic conditions may be used to facilitate data transmission by the NAK-based FL RLP.

摘要： To transmit overhead information for broadcast and multicast services in a system that utilizes multiple radio technologies, time slots used for OFDM in a super-frame are initially ascertained. Overhead information for multiple streams to be sent in the time slots used for OFDM is generated. The overhead information conveys the time slots and the coding and modulation used for the streams and may be given in various forms. Multiple records may be formed for the overhead information for the streams. The overhead information for the streams is processed and time division multiplexed with the data for the streams in the super-frame. Information indicating the time slots used for OFDM in the super-frame may be sent separately or included in the overhead information. An indicator may also be appended to each stream to indicate whether there is any change in the overhead information for the stream in the next super-frame.

摘要： To reduce inter-sector interference for "weak" users and combat a potentially large variation in interference levels observed by "strong" and weak users, system resources (e.g., frequency subbands) available for data transmission in a system are partitioned into multiple (e.g., three) disjoint sets. Each sector in the system is assigned one subband set. Neighboring sectors are assigned different subband sets such that the subband set assigned to each sector is orthogonal to the subband sets assigned to neighboring sectors. Each sector has an assigned subband set and an unassigned subband set, which contains all subbands not in the assigned set. Weak users in each sector (which are typically strong interferers to neighboring sectors) are allocated subbands in the assigned set. Strong users in each sector are allocated subbands in the unassigned set. The weak users in each sector are then orthogonal to strong interferers in neighboring sectors.

摘要： A system and method for power control and scheduling of sub-carriers in an OFDM communication system. The receiver dynamic range can be minimized by a power control loop that attempts to maintain received power over a noise floor in a predetermined range. If the received power relative to a noise floor in allocated sub-carriers exceeds the predetermined range and the total received power is at the minimum, the scheduling system allocates an additional sub-carrier to the communication link. Additionally, if the received power relative to the noise floor is less than the predetermined range minimum, and the total received power is at a maximum, the scheduling system de-allocates a sub-carrier from the communication link. The scheduling system may also adjust an encoding rate to maintain a relatively constant symbol rate in each sub-carrier.

摘要： Techniques for transmitting data in a relay communication network are described. In an aspect, stations in the relay network may be grouped into multiple depths, and stations at each depth may send the same transmission in each time interval. Packets may be transmitted in a pipelined manner in the relay network. Transmissions of a packet may be sent by stations at progressively higher depth in successive time intervals. A station may perform auto-configuration, attempt to decode transmissions from stations at different depths, and determine its depth based on decoding results. In another aspect, stations at each depth may transmit the same synchronization signal, and stations at different depths may transmit different synchronization signals. In one design, the synchronization signals for different depths may be different pilots, which may be generated with different scrambling codes or different orthogonal codes or may be multiplexed in frequency and/or time.
