Abstract: A method of operating a wireless terminal comprises awaking from a sleep mode of operation to receive a first paging signal; performing a non-coherent demodulation operation on the first paging signal to produce demodulated information; determining if the demodulated information indicates that a paging message was transmitted; and if it is determined that the demodulated information indicates that a paging message was transmitted, performing a coherent demodulation operation on a second paging signal. A wireless terminal comprises means for performing a non-coherent demodulation operation on a first paging signal to recover modulated information indicating whether a paging message corresponding to the first paging signal will be transmitted, control means for controlling the wireless terminal to receive a second paging signal of a second type at a pre-selected time when information recovered from the first paging signal indicates a paging message corresponding to the first paging signal will be transmitted and for controlling the wireless terminal to enter a sleep mode of operation and remain in the sleep mode of operation until after the pre-selected time when the information recovered from the first paging signal indicates a paging message corresponding to the first paging signal will not be transmitted; and means for performing a coherent demodulation operation on the received second paging signal to recover modulated information including at least a portion of a paging message.

Abstract: Method and apparatus for an access termi-nal which makes handoff decisions between a number of potential alternative attachment points based on service level indicating metrics are described. The access terminal computes a service level indicating metric differently for a current connection than for a potential alternative connec-tion. A service level indicating metric is a function of load-ing information and received signal strength. A selection may be made by selecting between attachment points by se-lecting the attachment point having the highest service lev-el indicating metric from among a plurality of attachment points, one per possible carrier where the attachment point which is considered for a given carrier is the one having the best connection for the given carrier. The access termi-nal handoff decision approach provides handoff decisions which are nearly as optimal as those which can be achieved using a centralized control node but without the require-ment for centralized handoff decisions.

Abstract: Systems and methodologies are described that facilitate utilizing power-based rate signaling for uplink scheduling in a wireless communications system. A maximum nominal power (e.g., relative maximum transmit power that may be employed on an uplink) may be known to both a base station and a mobile device. For example, the base station and the mobile device may agree upon a maximum nominal power. According to another example, signaling related to a maximum nominal power for utilization on the uplink may be provided over a downlink. Further, selection of a code rate, modulation scheme, and the like for the uplink may be effectuated by a mobile device as a function of the maximum nominal power. Moreover, such selection may be based at least in part upon an interference cost, which may be evaluated by the mobile device.

Abstract: Methods and apparatus for efficient two-stage paging wireless communications systems are described. Wireless terminals 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. 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.

Abstract: Methods and apparatus related to communicating and/or using load information in support of decentralized traffic scheduling decisions are described. Individual wireless terminals corresponding to a peer to peer connection which desire to communicate traffic signals make transmitter yielding and/or receiver yielding decisions on a traffic slot by traffic slot basis. Loading information is used to intentionally skew transmitter yielding decisions in response to conditions and/or needs in the system. A link load weight value is generated based on intended transmitter loading related information and/or intended receiver loading related information. Traffic request parameters and/or link load weight values are communicated between wireless communications devices in request and/or request response signaling. As part of a transmitter yielding decision, one or more of: a spillage value, weighted SINR, and an interference cost estimate is calculated based on: one or more link load weight values and channel condition measurement information.
