摘要： Transmission of sequences in wireless networks from a user equipment (UE) includes various types of reference signals, such as a sounding reference signal (SRS) and a physical uplink control channel (PUCCH) symbol. The UE receives (402) an indication of a reference signal sequence group number u, wherein physical uplink control channel (PUCCH) sequences are divided into groups having at least one sequence each and wherein sounding reference signal (SRS) sequences are divided into groups having at least one sequence each. The UE produces (414) a sequence from an SRS sequence group with the sequence group number u when an SRS is to be transmitted and produces (412) a sequence from a PUCCH sequence group with the sequence group number u when a PUCCH symbol is to be transmitted. The UE produces (416) a transmission signal using the produced sequence.

摘要： A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations. The transmission from the secondary to primary node in a wireless network (100) is obtained using a first and a second sequence. Embodiments of the present invention mitigate interference by restricting the choice of the first sequence. Thus, in an embodiment of the invention, the first sequence is selected from a set of M sequences wherein M is strictly less than N. In order to accommodate high-velocity (112) users, the restricted set contains a pair of sequences whose element-wise product is mirror symmetric. A transmission component for K-th logical time duration is obtained from the entire second sequence and K-th element of the first sequence.

摘要： Transmitting an ACWNACK response in a wireless cellular network by mapping the data value into a cyclic shifted version of a reference signal. A subframe is formed (704) with a plurality of symbols with certain symbols designated as reference signal (RS) symbols. The receiver and transmitter both know when an ACWNACK response is expected. If an ACWNACK response is not expected (706), then an RS is inserted (708) in the duration of symbols designated as RS symbols. If an ACWNACK response is expected, then the ACWNACK response is embedded (7 10) in one or more of the symbols designated as RS symbols. The subframe is transmitted (712) to a receiver, and the receiver can determine the ACWNACK value in the RS symbol, if present, and also use the RS symbol for coherent demodulation of a CQI (channel quality indicator) or data.

摘要： Transmission of information in a wireless network is performed by allocating a channel from a transmitter to a receiver. The channel has at least one time slot with each time slot having a plurality of symbols. Each slot contains at least one reference symbol (RS). As information becomes available for transmission, it is classified as prioritized information (PI) and other information (1304). Digital samples are produced using an element of prioritized information (1306). One or more priority symbols are generated using the digital samples (1308). Other symbols are generated using the other data (1310). Priority symbols are transmitted on the channel in a manner that separation of priority symbol(s) and a reference symbol does not exceed a time duration of one symbol. The other symbols are transmitted in available locations (1312).

摘要： Methods and apparatus to allocate reference signals in wireless communication systems are disclosed. A disclosed example apparatus comprises a reference signal generator (501) to generate a reference sequence (505) based on a parameter assigned to a wireless region, wherein the parameter specifies a first reference sequence to be transmitted by a first device of the wireless region during a first time interval, the first reference sequence being different from a second reference sequence assigned to a second device of a second wireless region adjacent to the first wireless region. The reference sequence generator comprises a cyclic shift selector (503) to select a cyclic shift for the first time interval based on the parameter and a cyclic shifter (506) to cyclically shift the first reference signal based on the selected cyclic shift. The example apparatus further comprises a transmit adapter (510) to transmit the cyclically shifted first reference sequence.

摘要： A transmission of information within a wireless cellular network may include a first and second group of samples. A first group (302b) of samples is created comprising at least a first (302a) and a last (402a) subgroup, wherein the last subgroup is same as the first subgroup. A second group (302d) of samples is created. A transformed set of samples is produced by jointly transforming the created first and second group with a discrete Fourier transform (DFT). The transformed set of samples is expanded to produce an expanded set, and the expanded set is transformed with an inverse discrete Fourier transform (IDFT) to produce an OFDM symbol with a fractional payload. The first group of samples is a reference signal (RS), which is known to the receiver before the transmission occurs, while the second group of samples is information data.
