    Abstract: A plurality of report dictionaries, e.g., uplink transmission backlog request report dictionaries, are supported in a wireless communications system. Each report dictionary provides bit mapping definition information corresponding to a set of fixed bit size request reports. Different report dictionaries are structured to accommodate different reporting conditions, needs, and/or requirements. A communications device selects a report dictionary, e.g., on a per connection basis, to be used in communicating transmission backlog information, from among the plurality of possible report dictionaries. Information characterizing active traffic flows such as the number of distinct quality of service profiles and/or the current mixture of best effort and latency constrained traffic flows is used in performing the selection of a report dictionary. The selected report dictionary is subsequently utilized to generate reports and interpret information communicated in those generated reports.

    Abstract: Methods and apparatus for indicating parameter change points with respect to multiple connections (wireless links) by transmitting a single message, e.g., over one of the connections, is described. A base station corresponding to at least one connection, considers the approximate timing relationship between the connections, selects one of the connections, selects an intended parameter switching point for that connection, determines a symbol time offset from the selected switching point such that the other intended switching points of other wireless links can be unambiguously interpreted by the wireless terminal from information indicating the offset with respect to the selected link, and communicates information indicating the offset and the wireless link to which said offset applies. A wireless terminal receives the information, identifies a time referenced with respect the timing structure of the identified wireless link and then determines individual parameter switching points for the other wireless links.

    Abstract: Wireless terminal for use with a multi-mode base station that supports a transmit standby mode and an active mode is described. Transmit standby mode of base station operation is a low power/low interference level of operation as compared to active mode. In transmit standby mode at least some of the synchronization signaling such as pilot tone signaling is reduced in power level and/or rate with respect to the active mode. In transmit standby mode, the base station has no active state registered wireless terminals being serviced but may have some sleep state registered wireless terminals being serviced. Mode transitions from active to transmit standby may be in response to: a detected period of inactivity, scheduling information, base station mode change signals, and/or detected wireless terminal state transition. Mode transitions from transmit standby to active may be in response to: scheduling information, access signals, wake-up signals from the wireless terminal, hand-off signals, etc.

    Abstract: In modern iterative coding systems such as LDPC decoder and turbo-convolutional decoder in which the invention may be used, the core computations can often be reduced to a sequence of additions and subtractions alternating between logarithm and linear domains A computationally efficient and robust approximation method for log and exp functions is described which involves using a simple bit mapping between fixed point fractional data format and floating point format. The method avoids costly lookup tables and complex computations and further reduces the core processing to a sequence of additions and subtractions using alternating fixed point and floating point processing units. The method is well suited for use in highly optimized hardware implementations which can take advantage of modern advances in standard floating point arithmetic circuit design as well as for software implementation on a wide class of processors equipped with FPU where the invention avoids the need for a typical multi-cycle series of log / exp instructions and especially on a SIMD FPU-equipped processors where log / exp functions are typically scalar.

    Abstract: Methods and apparatus for communicating information using a plurality of report dictionaries are described. A plurality of request dictionaries are implemented for a wireless terminal to use for multi-bit uplink transmission backlog request reports communicated via the dedicated control channel. Each dictionary defines a different bit mapping interpretation for a set of multi-bit uplink transmission backlog request reports, e.g. a 3 bit uplink request report and a 4 bit uplink request report. The plurality of request dictionaries includes a default dictionary and additional dictionaries. The implementation of a plurality of alternative request dictionaries expands the reporting possibilities allowing a wireless terminal to use a reporting format well- suited to its current needs. The default dictionary is mandated to be used under certain predefined conditions, e.g., upon entry into the active state. Rules for transitioning between different dictionaries and continuing to use a selected dictionary are described.
