Definitions

  • the method continues with the receiving of HARQ data indicating that the first data packet (carried by the first stream) was successfully decoded, while the second data packet (carried by the second stream) was not.
  • the wireless transceiver retransmits the second data packet in a single stream of a rank-1 MIMO transmission, and transmits corresponding control data for the single stream using the second associated control channel.
  • Figure 4 is a process flow diagram illustrating an example method for retransmission handling.
  • Figure 5 is a process flow diagram illustrating another example method for retransmission handling.
  • An access terminal can be a cellular telephone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device having wireless connection capability, computing device, or other processing device connected to a wireless modem.

Abstract

L'invention concerne une requête automatique de répétition hybride (HARQ) et des procédures de retransmission pour une transmission multiflux. Un procédé illustratif commence par l'envoi (410) simultané d'un premier et d'un deuxième paquet de données, respectivement dans le premier et le deuxième flux MIMO d'une transmission de classe 2, et par la transmission (420) de données de commande correspondantes respectivement pour le premier et le deuxième flux, à l'aide respectivement du premier et du deuxième canal de commande associé. Le premier et le deuxième canal de commande associé se distinguent par leur mappage respectif au signal transmis. Le procédé se poursuit par la réception (430) de données HARQ indiquant que le premier paquet de données a été décodé avec succès, tandis que le deuxième paquet de données ne l'a pas été. En réaction, l'émetteur sans fil retransmet (440) le deuxième paquet de données dans une transmission MIMO de classe 1 à flux unique, et transmet (450) des données de commande correspondantes pour le flux unique à l'aide du deuxième canal de commande associé.
