Data channel and control/management channel separation

Abstract:

Methods, systems, and devices for wireless communications are described. In some systems (e.g., Wi-Fi systems), two stations (STAs) may support communicating different information simultaneously via multiple links, channels, resource units, etc. Simultaneous communication may be enabled by a multi-band aggregation system, an enhanced preamble puncturing system, a multi-resource unit assignment system, a full duplex system, or some combination of these. A transmitting STA may transmit data to a receiving STA in a first set of resources while communicating different information with the STA in a second set of resources. The communicating may involve an additional transmission of data, control information, or management information, or receiving feedback from the receiving STA. In some examples, the data transmission may occur on a data channel, while the control information and feedback may occur on a control channel. The simultaneous communication may improve communication throughput while reducing feedback latency in the system.
