Abstract

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 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 data and control information are transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.

112. The apparatus of claim 100, wherein the time segments and each time interval are contiguous.

113. The apparatus of claim 100, further comprising:

means for defining a rate prediction state based on control information received prior to the first time period;

means for determining, based on the rate prediction state, at least one parameter for achieving sustainable reception of data during at least one of the time segments; and

means for scheduling, based on the at least one parameter, a requested transmission that provides the data received during the time segments.

114. The apparatus of claim 113, wherein the at least one parameter comprises at least one of the group consisting of:

a transmission time period, a transmission rate, a quantity of redundancy bits to transmit, and a code rate.
