摘要： Systems and methods for service period recovery in a wireless communications system are provided. An initial service period for transmitting data is assigned to a first remote station. Data period schedule information, including the assignment of the initial service period, is transmitted from a central station. In response to determining that the first remote station is not transmitting during the initial service period, a modified service period is assigned to the first remote station. A service period change announcement, including the assignment of the modified service period, is transmitted from the central station. In response to determining that the first remote station is not transmitting during the modified service period, the initial service period is truncated and a service period truncation is transmitted from the central station.

摘要： In a communication system that utilizes at least a primary channel, a secondary channel, and a tertiary channel, a primary channel signal level in the primary channel is measured, and a secondary channel signal level in the secondary channel is measured. A first tertiary channel signal level in a first bandwidth portion of the tertiary channel is measured, and a second tertiary channel signal level in a second bandwidth portion of the tertiary channel is measured. It is determined whether the primary channel is idle based on the primary channel signal level, and it is determined whether the secondary channel is idle based on the secondary channel signal level. It is determined whether the tertiary channel is idle based on the first tertiary channel signal level and the second tertiary channel signal level. It is determined whether a valid signal is received via a first composite channel including the primary channel, the secondary channel, and the tertiary channel. A first composite channel signal level in the first composite channel is measured at least when it is determined that a valid signal was received via the first composite channel. It is determined whether the first composite channel is idle based on i) whether a valid signal was received via the first composite channel and ii) the first composite channel signal level at least when it is determined that a valid signal was received via the first composite channel.
