Patent number: 9949216Abstract: This disclosure relates to optimizing power consumption for cellular communication based on transport block size in combination with channel condition measurements via power amplifier biasing. According to one embodiment, an indication of a transport block size to be used for uplink communication with a base station may be received. It may be determined that the transport block size provides more robust communication characteristics than required for current channel conditions. A power amplifier (PA) bias current for uplink communication with the cellular base station may be selected based at least in part on determining that the transport block size provides more robust communication characteristics than required for the current channel conditions. In particular, PA bias current selection may be biased to reduce power consumption at a cost of greater non-linearity based on the transport block size providing more robust communication characteristics than required for the current channel conditions.Type: GrantFiled: September 22, 2014Date of Patent: April 17, 2018Assignee: Apple Inc.Inventors: Vinay R.

Patent number: 9942857Abstract: The present document relates to a method for transmitting and receiving signals by controlling interference on other wireless devices based on actual transmitted power or received power information in a wireless communication system, and an apparatus therefor. To this end, STA 1 receives from STA 2 a frame comprising power information about actual transmitted power or actual received power of STA 2. Through the frame, STA 1 determines transmitted power by correcting the existing transmitted power of STA 1 by using the power information of STA 2 and, when the determined transmitted power of STA 1 is less than or equal to a reference value, transmits signals through the frame.Type: GrantFiled: November 21, 2014Date of Patent: April 10, 2018Assignee: LG Electronics Inc.Inventors: Dongguk Lim, Jinyoung Chun, Wookbong Lee, Jinsoo Choi, Hangyu Cho
