摘要： A method for reducing the peak-to-average ratio into an OFDM communication signal is provided. The method includes defining a constellation having a plurality of symbols, defining a symbol duration for the OFDM communication signal, and defining a plurality of time instants in the symbol duration. A plurality of tones are allocated to a particular communication device, and a discrete signal is constructed in the time domain by mapping symbols from the constellation to the time instants. A continuous signal is generated by applying an interpolation function to the discrete signal such that the continuous signal only includes sinusoids having frequencies which are equal to the allocated tones.

摘要： Improved beacon signaling methods are described. Beacon signals are transmitted on the same tone in at least two consecutive symbol periods facilitating accurate energy measurements over a symbol period even if timing synchronization with the transmitter is not maintained. A low power wideband signal is also combined with the beacon signal to facilitate channel estimation and other operation such as timing synchronization operations.

摘要： In many cellular systems, reusing spectrum bandwidth, creates problems in boundary regions between the cells and sectors where the signal strength received from adjacent base stations or adjacent sector transmissions of a single base station may be nearly equivalent. The invention creates a new type of diversity, referred to as multiple carrier diversity by utilizing multiple carriers, assigning different power levels to each carrier frequency at each base station, and/or offsetting sector antennas. The cell and/or sector coverage areas can be set so as to minimize or eliminate overlap between cell and/or sector boundary regions of different carrier frequencies. Mobile nodes traveling throughout the system can exploit multiple carrier diversity by detecting carriers and selecting to use a non-boundary carrier based on other system criteria in order to improve performance. Boundary carriers may, but need not be, identified and excluded from consideration for use by a wireless terminal.

摘要： A terminal is assigned an active identifier for use while in an active state of a connection with a base station. The base station periodically broadcasts the status of the active identifiers for that base station, e.g., via status validation bits that indicate whether each active identifier is currently assigned to a terminal or not assigned to any terminal. The base station may also broadcast the identity (e.g., a scrambling mask) of the terminal assigned with each active identifier that is currently in use. If a terminal believes that it is assigned a particular active identifier, then the terminal checks the status validation bit for this active identifier. If this status validation bit indicates that the active identifier is currently in use, then the terminal may further check the scrambling mask sent for the active identifier in order to determine whether the terminal is actually assigned the active identifier.

摘要： Methods and apparatus of efficient communication of resource allocation are described. A base station transmits a resource assignment message, e.g., a state transition message, to a wireless terminal including a first part, e.g., a base station assigned wireless terminal On state identifier, identifying a resource being assigned and a second part, e.g., an ON state mask, identifying a portion of the resource allocated to the wireless terminal. The same resource allocation message information also communicates one of a plurality of different modes of commanded On state operation. The resource allocation message structure supports flexible allocation of available resources facilitating a resource to be partitioned differently at different times accommodating current needs. A predetermined recurring channel structure and association of segments with particular mask bits, facilitates allocated control segments to be used unambiguously without the need to include an overhead wireless terminal identifier field with the control report bits being communicated.

摘要： Techniques for paging terminals in a wireless (e.g., OFDMA) communication system to achieve both fast paging response and low power consumption for the terminals are described. A terminal receives paging indicator from a base station. If the paging indicator indicates that the terminal is potentially being paged, then the terminal receives at least one paging message from a paging channel. The terminal determines whether any one of the at least one paging message is for the terminal, e.g., based on identification information included in each paging message. If a paging message indicates that the terminal is paged, then the terminal sends an acknowledgement for the paging message. The base station may estimate the timing of the terminal based on the acknowledgement and may send timing adjustment to the terminal. The terminal may adjust its timing based on the timing adjustment and may be able to quickly access the system with no contention.

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： Methods and apparatus for efficient two-stage paging wireless communications systems are described. Wireless terminals (300) are assigned to paging groups. A few first paging message information bits are modulated (using non-coherent modulation) into a first paging signal and communicated from a base station to wireless terminals (200). WTs wake-up, receive the first paging signal and quickly ascertain whether its paging group should expect a second paging signal, if so, the WT is operated to receive the second paging signal; otherwise, the WT goes back to sleep conserving power. The base station modulates (using coherent modulation) a number of second message information bits into a second paging signal and transmits the signal to WTs. From the information in first and second paging signals, a WT can determine that it is the paged WT and process the paging instructions. The intended paged WT can transmit an acknowledgement signal on a dedicated uplink resource.

摘要： More efficient utilization of available bandwidth is implemented in an OFDM wireless communication system. The partitions of bandwidth may be of different sizes and may be different from the original system design parameters. Basic system structure such as the number of tones used and the number of OFDM symbol times in a slot is maintained throughout the system. Bandwidth is varied by adjusting the inter-tone spacing or bandwidth associated with a single tone. As the inter-tone spacing is increased, the OFDM symbol transmission time is decreased following an inverse proportional relationship. A wireless communications device, during a first period of time transmits signals using a first uplink frequency band of a first number of uniformly distributed tones and during a second period of time transmits signals using a second uplink frequency band of a second number of uniformly distributed tones, the second number being the same as the first number, the second frequency band being wider than the first frequency band.
