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.
