Sub-channels are defined for a physical random access channel of a wireless time division duplex communication system using code division multiple access. The sub-channels carry information between system users and a system network. A series of radio frames have a sequence of timeslots. For a particular timeslot number of the sequence, each sub-channel of the particular timeslot number is uniquely defined by one radio frame of the series.

L'invention concerne des sous-canaux qui sont définis pour un canal physique d'accès aléatoire d'un système de communication en duplex à répartition dans le temps utilisant un accès multiple par code de répartition. Les sous-canaux transmettent des informations entre des utilisateurs du système et un réseau du système. Une série de trames radio présente une suite d'intervalles de temps. Pour un intervalle de temps particulier de la suite, chaque sous-canal du numéro de l'intervalle de temps particulier est uniquement défini par une trame radio de la série.
