Abstract:
1. A method of controlling transmit power in a data terminal constrained to operate within an aggregate transmit power limit, the data terminal including N wireless modems having their respective transmit outputs combined to produce an aggregate transmit output, the method comprising: (a) establishing an individual transmit power limit in each of the N modems; (b) scheduling each of a plurality of the N modems to transmit respective data; (c) receiving a respective, reported transmit power estimate from each of the N modems; and (d) adjusting the individual transmit power limits in at least some of the N modems based on the aggregate transmit power limit and the respective transmit power estimates from the N modems, to cause each individual transmit power limit to track a corresponding individual modem transmit power; and (e) periodically repeating steps (b), (c) and (d) to cause the individual transmit power limits to track changes in the corresponding modem transmit powers over time.
