CROSS-LAYER MULTI-PACKET RECEPTION BASED MEDIUM ACCESS CONTROL AND RESOURCE ALLOCATION

摘要

A cross-layer multi-packet reception media access control and resource allocation technique is provided for wireless networks having receivers with multiple antennas. User devices on the wireless network access the network for data transmission by making a request to send (RTS) request after a random backoff time. In response to a request to send, an access point (or other receiver) determines transmission parameters that optimize the use of the physical layer based at least in part on channel state information. Those transmission parameters are transmitted along with a clear to send (CTS) message from the receiver to an indicated transmitter. Once the CTS message is received, data is transmitted in accordance with transmission parameters.
