Abstract

A wireless communication device includes: an antenna for receiving inbound signals on dual receive channels and transmitting outbound signals on dual transmit channels; a transceiver coupled to the antenna to receive the inbound signals from the antenna and convey the outbound signals; a power controller coupled to the transceiver to control power levels of the outbound signals so a maximum nominal power level of the outbound signals is a first power level; and a processor coupled to the transceiver and the antenna to cause the power controller to control the power levels of the outbound signals so if a power level of a received one of the inbound signals is below a threshold value, then the maximum nominal power level of the outbound signals is a second power level lower than the first power level, wherein the second power level is lower than the first power level.

Description

[0001] Priority claims based on 35 U.S.C. §119 [0002] This patent application claims Provisional Application No. 61 / 303,588, filed February 11, 2010, entitled "Additional Maximum Power Reduction with Dual Uplink Transmissions in HSPA" and filed February 12, 2010, entitled " Priority to Provisional Application No. 61 / 304,231 for Additional Maximum Power Reduction with Dual Uplink Transmissions in HSPA", both of which have been assigned to the assignee of the present application and are expressly incorporated herein by reference. technical field [0003] Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to power control methods and apparatus for dual uplink transmissions in High Speed ​​Packet Access (HSPA) networks. Background technique [0004] Wireless communication networks are widely deployed to provide various communication services such as calling, video, data, messaging, broadcasting, and so on. These networ...
