摘要： Methods, systems, and devices for wireless communications are described. A transmitting wireless device may identify different sets of bits that are included in information bits of a signal to be transmitted. For example, a first set of bits may be used as an index for a second set of bits, and the second set of bits may include multiple groups of bits, where each group may have a same size (e.g., a same quantity of bits). Based on the groups of bits having the same size, the transmitting wireless device may obtain candidate partial transmit sequences (PTSs) based on applying phase rotations to respective inverse Fast Fourier Transform (IFFT) outputs associated with each group of bits. The transmitting wireless device may select a PTS from the candidate PTSs and may transmit the signal including the information bits to a receiving wireless device using the selected PTS.

摘要： Embodiments herein include a method in a user equipment (UE) for transmitting uplink control information in time slots of a subframe over a radio channel to a radio base station. The uplink control information is comprised in a block of bits. The UE maps the block of bits to a sequence of complex valued modulation symbols. The UE block spreads the sequence across Discrete Fourier Transform Spread-Orthogonal Frequency Division Multiplexing (DFTS-OFDM) symbols. This is performed by applying a spreading sequence to the sequence of complex valued modulation symbols, to achieve a block spread sequence of complex valued modulation symbols. The UE further transforms the block-spread sequence, per DFTS-OFDM symbol. This is performed by applying a matrix that depends on a DFTS-OFDM symbol index and/or slot index to the block-spread sequence. The UE also transmits the block spread sequence, as transformed, over the radio channel to the radio base station.

摘要： The present disclosure describes the generation of long sequences from short sequences to support concurrent transmissions of large numbers of machine-type communication devices operating in a wireless communication system. These long sequences may be assigned to devices so that the devices can use the long sequences scramble their transmissions. The use of such long sequences permits many machine-type communication devices to transmit during the same time and frequency resource.

摘要： A seeding control system and method to improve yield by minimizing overplanting and underplanting during planting operations. As the planter traverses the field, a precise seed placement map is created by associating the time of each seed pulse generated by the seed sensors with the location of a GPS unit. Based on the generated seed placement map, a stop-planting boundary is defined by previously planted seed or other field boundary such that when a swath of the planter crosses over the stop-planting boundary the swath controllers disengage the drivers of the corresponding seed meters to prevent planting of seeds. The swath controllers cause the drivers to reengage allowing planting to resume when the affected swaths pass out of the stop planting boundary.
