Method and apparatus for available bandwidth estimation by a user equipment in idle and/or connected mode

摘要

A method and apparatus for determining available downlink bandwidth are described. The described aspects may include estimating an available link capacity of a cell for a user equipment. The described aspects may include estimating an available fraction of cell resources for the user equipment. The described aspects may include estimating available bandwidth of the cell for the user equipment as a function of the estimated available link capacity and the estimated available fraction of cell resources. Available bandwidth may be estimated for a cell in a Universal Mobile Telecommunications System (UMTS) system when the user equipment is in an idle mode and/or a connected mode. Available bandwidth may be estimated for a cell in a Long Term Evolution (LTE) system when the user equipment is in an idle mode and/or a connected mode.

主权项

1. A method for determining available downlink bandwidth, comprising:
estimating a supported rate of a cell for a user equipment based at least in part on a measured signal energy of the cell, wherein a function of the supported rate comprises determining a total bandwidth corresponding to a total number of an available number of codes used by the cell for the supported rate; estimating an available number of codes for the cell based at least in part on a number of codes per one or more past scheduling events, wherein a function of the available number of codes comprises scaling a total bandwidth based on at least one of an available number of codes; estimating an available bandwidth of the cell for the user equipment as a function of the supported rate and the available number of codes; and performing, by the user equipment, one or more network communications procedures with the cell based at least in part on the estimated available bandwidth.
