Context and power control information management for proximity services
Management of context and power control information enables different power control schemes for point-to-point or point-to-multipoint based on proximity services or applications. Context information may be defined as situation data about a service or application that is used to help define a power control scheme to be implemented. Power control information may be defined as control or status data for power control, which can be used for reporting or controlling the transmitting power of a peer in a P2P network. Context and power control information may be managed across multiple layers such as the application layer, service layer, media access control layer, or physical layer. Context and power control information is updated and exchanged between or among peers for context-related power control in proximity services.
