Multi channel stop and wait arq communication method and apparatus
TL;DR: In this paper, the authors propose a method in which a communication system (100) includes transmitting from a source user (101) a first data packet (111) over a first time frame (121) having a finite time period (131).
Patent
Mobile assisted downlink beamforming with antenna weight feedback
TL;DR: In this paper, the downlink beamforming weights were derived at the subscriber unit from a prior downlink transmission from the base station (102) to the subscriber device (104) and an uplink sounding signal was used to carry derived downlink beacon forming weights to the base-station (102).

Power control for CDMA communication systems
Amitava Ghosh,Kamyar Rohani +1 more
TL;DR: In this paper, the received power control groups are analyzed and compared to several levels of energy thresholds (73, 75, 77, 79, 80, 81) and the results of the comparisons are converted into a power control signal and returned to the mobile.
Patent
Method and apparatus for uplink resource allocation in a frequency division multiple access communication system
TL;DR: In this article, a resource allocation scheme that results in a better tradeoff between cell-edge performance and overall spectral efficiency was proposed to achieve a level of performance desired for uplink transmissions in 3GPP (Third Generation Partnership Project).
