Conditional requests for asynchronous wireless communication

摘要

A wireless media access control supports asynchronous communication and overlapping transmissions. Here, a wireless node may determine whether to request or schedule a transmission based on control messages it receives from neighboring nodes. In some implementations a scheduled transmission may be divided up into several segments so that a transmitting node may receive and transmit control messages between segments. In some implementations a monitoring period is defined after a scheduled transmission period to enable the transmitting node to acquire control information that may otherwise have been transmitted during the scheduled transmission period. In some implementations data and control information are transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.

1. A method of wireless communication, comprising:
receiving, at a first wireless node, information that indicates a scheduled reception of data for a second wireless node, wherein the received information comprises at least one transmission parameter defined by the second wireless node and at least one timing parameter, and wherein the at least one transmission parameter comprises at least one transmit power parameter; determining, at the first wireless node based on the received information, whether transmission by the first wireless node to a third wireless node would interfere with reception at the second wireless node; and determining, based on the interference determination, whether to transmit from the first wireless node to the third wireless node during a time period associated with the scheduled reception of data.
