Systems and methodologies are described that provide half-duplex communication in a frequency division duplex (FDD) system. Communications in an FDD system may be divided into half-duplex interlaces, wherein a terminal may receive at one time period and transmit at another time period. An access network in an FDD system may then utilize half-duplex communication to communicate with an access terminal that is not capable of transmitting and receiving simultaneously by using a half-duplex interlace. Further, an access network may also utilize full-duplex communication to communicate with an access terminal that is capable of transmitting and receiving simultaneously.

L'invention concerne des systèmes et des méthodologies qui assurent la communication en semi-duplex dans un système duplex par répartition de fréquence (FDD). Les communications dans un système FDD peuvent être divisées en entrelacements en semi-duplex, un terminal pouvant recevoir à un moment donné et émettre à un autre moment donné. Un réseau d'accès dans un système FDD peut alors utiliser la communication en semi-duplex pour communiquer avec un terminal d'accès qui ne peut pas émettre et recevoir simultanément en utilisant un entrelacement en semi-duplex. De plus, un réseau d'accès peut également utiliser la communication en semi-duplex pour communiquer avec un terminal d'accès pouvant émettre et recevoir simultanément.
