摘要： A method for transmitting information in a multi-carrier system includes: identifying a first set of carrier signals, associated with a first code rate; and identifying a second set of carrier signals, associated with a second code rate. The method also includes partitioning a first sequence of bits representing a single symbol into a first group of bits associated with the first code rate and at least a second group of bits associated with the second code rate; interleaving a subset of bits from the first group to map multiple bits from the first group to respective carrier signals in the first set of carrier signals to achieve the first code rate; and interleaving a subset of bits from the second group to map multiple bits from the second group to respective carrier signals in the second set of carrier signals to achieve the second code rate.

摘要： Transmitting information between stations in a network includes: modulating first main information and auxiliary information onto a first portion of a signal according to a predetermined constellation having multiple regions and the same sub-constellation within each region having multiple points, with the first main information being modulated using a first selected region of the constellation, and the auxiliary information being modulated using a first selected point of the sub-constellation within the first selected region; modulating second main information and a copy of the auxiliary information onto a second portion of the signal according to the constellation, with the second main information being modulated using a second selected region of the constellation, and the copy of the auxiliary information being modulated using a second selected point of the sub-constellation within the second selected region, where the second selected point occurs at a different portion of the sub-constellation than the first selected point; and transmitting the signal from a first station in the network to a second station in the network.

摘要： Dynamic channel reuse in multi-access communication systems. A first station in a communication network may receive a transmission over a communication medium. The first station may generate a reuse determination based on information from the received transmission. The reuse determination may be usable with at least one other reuse determination to coordinate reuse of the communication medium.

摘要： Communicating between stations in a network is described. A plurality of stations coordinate according to a distributed protocol to select a first station to transmit over a shared medium. The communication includes transmitting between the first station and a second station over the shared medium during a time period in which stations other than the first and second stations refrain from transmitting over the shared medium. The first station transmits information that grants permission to the second station to transmit during the time period.
