摘要： Methods and apparatus for improved beacon signaling in a wireless communication system are described. Information is encoded in the tone position of the beacon tone. The information encoded may include sector type, sector index and slope index, as well as some time index. The information is coded in the tone position so that any few of several beacons can be decoded in order to decode the information. The methods and apparatus described in the invention improve the robustness against frequency selective fading and do not require wireless terminals to establish synchronization for reliable base station detection.

摘要： A composite signal includes a high power beacon signal and low power corresponding wideband synchronization signal and is communicated over a time interval exceeding a single OFDM transmission time interval. A base station transmits one or more different such composite broadcast signals in a recurring timing structure. Each different potential beacon signal, e.g., a single tone signal, is paired with a unique wideband synchronization signal. A wideband synchronization signal includes at least some predetermined null tones and at least some predetermined non-null tones. For a given wideband synchronization signal, the predetermined null tones carry predetermined modulation symbol values, A wireless terminal receives a composite signal, identifies a beacon, determines a corresponding known wideband synchronization signal, compares received to known wideband synchronization signals, and determines at least one of a timing adjustment, frequency adjustment and channel estimation.

摘要： An access node, e.g., base station, determines a configuration of an end node, e.g., wireless terminal, intended to support a specific traffic flow and sends a configuration command to the wireless terminal. A base station may determine one or more parameters associated with classification, queue management, scheduling, and/or automatic repeat request, and then send a configuration command to the wireless terminal instructing it to implement a configuration operation. In some embodiments, a wireless terminal sets the value of an internal parameter to a value directly provided by the base station in a configuration command. In some embodiments, a wireless terminal determines and sets the value of an internal parameter as a function of information included in the configuration command from the base station.

摘要： Methods and apparatus related to assignment in a wireless communications system are described. A mobile is assigned an identifier and a mask value, e.g., as part of a state transition message. The mobile uses the assigned identifier and/or the assigned mask value in determining whether assignments included in assignment messages, e.g., traffic channel assignment messages, are directed to the wireless terminal. Predetermined associations between assignment slots, assigned segments, and/or mask values are utilized to limit control signaling overhead. Different groups of segments are available for assignment to different wireless terminals as a function of mask values. Different types of assignment messages use different amounts of information bits to convey the assignment. Some types of assignments use a wireless terminal identifier, while other types of assignments use a wireless terminal identifier and a mask identifier. The mask identifier, e.g., a single bit, allows for selection between a subset of the potential masks used in the system.

摘要： In a first mode of dedicated control channel (DCCH) operation, a wireless terminal is allocated more segments than in a second mode. The wireless terminal uses different information bit to modulation symbol mapping in the different modes. On a per DCCH segment basis, the same number of modulation symbols are communicated in either mode but more information bits are conveyed in the second mode. Information bits for a DCCH segment are partitioned into two subsets. The two subsets are used to generate another set, each of the two subsets and the another set are input to the same mapping function to generate three equal size sets of modulation symbols which are transmitted via the DCCH segment. Uplink tone hopping is used such that one of the equal size sets of modulation symbols for the DCCH segment uses the same tone but a different set uses a different tone.
