Abstract:
1. A transceiver for a wireless mobile device, comprising: a transmitter configured to transmit over a transmission band occupying a first portion of a first white space TV channel, wherein the first portion of the first white space TV channel has a narrower bandwidth than a standard TV channel to enable the transceiver to satisfy a predetermined spectrum mask requirement; a receiver configured to receive over a receiving band occupying a second portion of a second white space TV channel; and a bandwidth-determination mechanism configured to determine an optimal downlink-to-uplink bandwidth ratio based on a current power budget of the mobile device to satisfy the predetermined spectrum mask requirement under the current power budget, wherein the downlink-to-uplink bandwidth ratio indicates a ratio of the second portion of the second white space TV channel to the first portion of the first white space TV channel, and wherein while determining the optimal downlink-to-uplink bandwidth ratio, the bandwidth-determination mechanism is further configured to: determine whether the wireless mobile device is on battery power; and in response to determining that the mobile device is on battery power, reduce the first portion of the first white space TV channel to a smaller portion.
