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.

摘要： A transmission of information between a secondary to a primary node in a wireless network occurs in a plurality of N logical time durations (310-319). Bundled feedback information for multiple downlink (DL) transmissions (340 and 342) is provided in one uplink (UL) transmission. Each downlink transmission (310) is indicated by a downlink grant (320) comprising an M-bit downlink assignment indicator (DAI) field (330). The primary node increments the value of the M-bit downlink assignment indicator field in successively transmitted downlink grants. The secondary node examines the value of the M-bit downlink assignment indicator field in received downlink grants, to determine the bundled feedback information.

摘要： Transmission of random access preamble structures within a cellular wireless network is based on the use of cyclic shifted constant amplitude zero autocorrelation ("CAZAC") sequences to generate the random access preamble signal. A pre-defined set of sequences is arranged in a specific order. Within the predefined set of sequences is an ordered group of sequences that is a proper subset of the pre-defined set of sequences. Within a given cell, up to 64 sequences may need to be signaled. In order to minimize the associated overhead due to signaling multiple sequences, only one logical index is transmitted by a base station serving the cell and a user equipment within the cell derives the subsequent indexes according to the pre-defined ordering. Each sequence has a unique logical index. The ordering of sequences is identified by the logical indexes of the sequences, with each logical index uniquely mapped to a generating index. When a UE needs to transmit, it produces (1410) a second sequence using the received indication of the logical index of the first sequence and an auxiliary value and then produces a transmission signal by modulating the second sequence. The auxiliary value is selected (1408) from one of two sets based on a set indicator broadcast (1404) by the eNB.

摘要： Apparatus and methods for accessing a wireless telecommunications network by transmitting a random access signal. The random access signal includes a random access preamble signal selected from a set of random access preamble signals constructed by cyclically shift selected root CAZAC sequences. The random access signal may be one or more transmission sub-frames in duration, the included random access preamble sequence's length being extended with the signal to provide improved signal detection performance in larger cells and in higher interference environments. The random access signal may include a wide-band pilot signal facilitating base station estimation of up-link frequency response in some situations. Each of the plurality of available random access preamble sequences may be assigned a unique information value. The base station may use the information encoded in the random access preamble to prioritize responses and resource allocations. Random access signal collisions are dealt with by a combination of preamble code space randomness and back-off procedures.

摘要： A transmission of information from a secondary to a primary node occurs in a plurality of transmission instances which are logical time durations. A secondary node receives (702) an allocation of periodic transmission instances for a schedule request indicator (SRI) and an allocation if periodic transmission instances for a sounding reference signal (SRS). In a particular transmission instance allocated (704) for the transmission of both SRS and SRI, the secondary node transmits (710) the SRI without transmitting the SRS if the SRI indicates (706) a pending scheduling request; otherwise, the secondary node transmits (708) the SRS without transmitting the SRI.

摘要： In described examples, a wireless device (101) includes a preamble detector configured to identify preambles transmitted via a random access channel of a wireless network (100). The preamble detector includes a noise floor estimator. The noise floor estimator is configured to estimate, for a given preamble root sequence identified by the preamble detector, a noise floor value as mean energy of received signal samples, excluding detected preamble samples on the given preamble root sequence, below a noise floor threshold assigned to the given preamble root sequence. The noise floor estimator is configured to compute the noise floor threshold as a product of: average energy of the received signal samples less total signal energy contained in each cyclic prefix window in which a preamble is detected using the given preamble root sequence; and a predetermined normalized relative noise floor threshold based on a target false preamble detection rate.

摘要： Methods, systems, and devices for wireless communications are described. In some systems, a wireless device may perform blind detection to attempt to receive and decode a polar encoded transmission with unknown transmission parameters. The device may receive a decoding candidate for a codeword and may attempt to decode the candidate according to a first number of information bits. If an error detection check (EDC) fails for the decoding paths resulting from this decoding attempt, the wireless device may extract, from the decoding paths, additional decoding paths of a shorter length. These extracted paths may correspond to a second number of information bits smaller than the first number of information bits. The device may perform an EDC on these extracted paths to determine if any path corresponds to the successfully decoded codeword. This procedure supports reducing the number of decoding processes needed to test different information bit sizes for a codeword.

摘要： Systems and methods for automated workflow comprise assigning a set of first targets to an uncompiled first workflow. The uncompiled first workflow specifies a first set of process modules. Each such module is associated with a subset of unit operations. Each unit operation includes a time interval and specifies an instrument. For each target in the set of first targets, the uncompiled workflow is translated into an instance of a compiled first workflow comprising a linear temporal order of unit operations, each including execution instructions for an addressed instrument. A set of second targets is obtained and assigned a second uncompiled workflow. Compilation of the second uncompiled workflow for each second target produces a different instance of a compiled second workflow. Each second compiled workflow comprises a linear temporal order of unit operations, with each unit operation including execution instructions for an addressed instrument and specifying a time interval.
