Title:
APPARATUS AND METHODS OF ENERGY EFFICIENT COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2014/008032
Kind Code:
A3
Abstract:
A method of energy efficient wireless communication, including obtaining a signal pattern defining resources for use in transmitting or receiving signals with variable signal density over time, the signals including a plurality of signals defining a signal burst, configuring the resources based on the signal pattern, including aligning a discontinuous reception (DRX) period with the signal burst, and transmitting or receiving the signals, including the signal burst aligned with the DRX period, according to the signal pattern to achieve variable density signal transmission or reception over time. Additionally, a method may include obtaining a signal pattern that defines a first set of signals with a first density and a first periodicity and a second set of signals with a second density different than the first density and a second periodicity different than the first periodicity, and communicating reference signals among the plurality of communications devices based on the signal pattern.
