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.

Description

technical field [0001] In general, the following description relates to wireless communications, and more specifically, to transmitting power-based rate signaling for uplink scheduling in wireless communications systems. Background technique [0002] Wireless communication systems have been widely used to provide various types of communication; for example, voice and / or data may be provided via a wireless communication system. A typical wireless communication system or network provides multiple users with access to one or more shared resources. For example, the system may use various multiple access techniques such as Frequency Division Multiplexing (FDM), Time Division Multiplexing (TDM), Code Division Multiplexing (CDM), and Orthogonal Frequency Division Multiplexing (OFDM), among others . [0003] A typical wireless communication system uses one or more base stations to provide coverage. A typical base station may transmit multiple data streams for broadcast, multicast...
