CA 2542384

Techniques for MAC processing for efficient use of high throughput systems that is backward compatible with various types of legacy systems are disclosed. In one aspect a first signal is transmitted according to a legacy transmission format to reserve a portion of a shared medium, and communication according to a second transmission format transpires during the reserved portion. In another aspect, a communication device may contend for access on a legacy system, and then communicate according to a new class communication protocol with one or more remote communication devices during the access period. In another aspect, a device may request access to a shared medium according to a legacy protocol, and, upon grant of access, the device may communicate with or facilitate communication between one or more remote stations according to a new protocol.

L'invention concerne des techniques de traitement de contrôle d'accès à des supports permettant une utilisation efficace de systèmes à rendement élevé, compatibles avec divers types de systèmes existants. Dans un aspect de l'invention, un premier signal est transmis sur la base du format de transmission existant pour réserver une partie d'un support partagé et une communication avec un second format de transmission apparaît durant la partie réservée. Dans un aspect, un dispositif de communication peut rivaliser pour l'accès sur un système existant, puis communiquer avec une nouvelle classe de protocole de communication avec un ou plusieurs dispositifs de communication à distance durant la période d'accès. Dans un autre aspect, un dispositif peut demander l'accès à un support partagé en fonction d'un protocole existant et, lors de l'autorisation d'accès, communiquer avec un ou plusieurs postes à distance ou faciliter la communication entre un ou plusieurs postes à distance en fonction d'un nouveau protocole.
