AI Technical Summary

Problems solved by technology

This unscheduled mode of operation is called "idle listening" and affects power consumption due to the continuous scanning of access points (APs) or other devices in the network for transmissions
For large bandwidth systems (for example, gigahertz (GHz) bandwidth), high-speed analog-to-digital converters (ADCs) are required for operation, and high-speed analog-to-digital converters can consume most of the idle listen mode power consumption

Abstract

In wireless communication systems, transmitters and receivers implement low-power synchronization techniques. The transmitter sends a packet including a two-part preamble. The first part of the two-part preamble is sent at a first reduced bandwidth that is less than the second bandwidth of the channel, and at least one of the second part of the two-part preamble and another part of the packet is sent at the second bandwidth of the channel. The receiver includes an interleaved ADC comprising a plurality of sub-analog-to-digital converters (ADCs). The receiver turns on a first subset of the plurality of sub-ADCs during an idle listening period, and turns on a second subset of the plurality of sub-ADCs upon detection of completion of the first part of the two-part preamble, wherein the first subset of the plurality of sub-ADCs A subset is smaller than a second subset of the plurality of sub-ADCs.

Description

technical field [0001] The present application relates generally to physical layer design aspects in wireless communication systems, and more particularly, to synchronization in high bandwidth wireless local area network (LAN) systems. Background technique [0002] A wireless LAN system, such as a wireless LAN system based on the Institute of Electrical and Electronics Engineers (IEEE) standard 802.11, is, for example, a packet-based communication system in which the entire information to be transmitted from a transmitter to a receiver is encoded in packets. A packet includes a preamble for synchronization, a header providing information about the content of the data, and a payload including the information to be transmitted. In current wireless local area network (LAN) systems, preambles, headers, and payloads are time multiplexed in packets and occupy the entire channel bandwidth for transmission and reception. [0003] In the unscheduled mode of operation using Carrier S...
