摘要
In a wireless local area network (LAN), such as one that is compatible with the HIPERLAN 2 standard, scheduling of long channel (LCH) PDUs and short channel (SCH) PDUs is based on an awareness of desired ARQ response time. Accordingly, mobile terminals and access points, particularly those that are communicating over time critical connections, are afforded a maximum amount of time to generate ARQ messages, while still achieving a fast response time. For example, in the more likely scenario where the uplink channel (ULCH) precedes the downlink channel (DLCH) in the Medium Access Control (MAC) data frame, the amount of time needed to generate an ARQ message may be maximized by scheduling the SCHs associated with a given connection so that they follow the corresponding LCHs in the ULCH of the MAC frame, and where the SCHs precede the corresponding LCHs in the DLCH of the MAC frame.
