Dynamic bandwidth switching for reducing power consumption in wireless communication devices

摘要

Systems, methods, apparatuses, and computer-program products for performing dynamic bandwidth switching between control signals and data signals of differing bandwidths are disclosed. Frame formats are disclosed in which control signals are transmitted at different bandwidths than data signals. Receiver architectures for receiving the signaling formats are disclosed. A receiver can receive a relatively narrowband control signal while consuming a relatively low power and then dynamically adjust characteristics of various components to receive a data signal at a higher bandwidth while consuming a relatively higher power.

主权项

1. A method of wireless communication, comprising:
transmitting a control signal to a mobile device using a first bandwidth; and transmitting a data signal to the mobile device using a second bandwidth wider than the first bandwidth, wherein the control signal and the data signal are transmitted over a single carrier frequency, wherein the control signal comprises an indication of a characteristic of the data signal, and wherein the data signal is transmitted after the control signal such that the data signal and control signal are separated by a time interval, wherein the time interval is based on a switching latency of the mobile device.
