SDMA MULTI-DEVICE WIRELESS COMMUNICATIONS

COMMUNICATIONS SANS FIL MULTI-DISPOSITIF À ACCÈS MULTIPLE PAR RÉPARTITION SPATIALE (SDMA)
Abstract:
(EN)
The present disclosure includes systems and techniques relating to wireless communications. A described system, for example, includes a device configured to transmit signals, in a frequency band, to the wireless communication devices. The signals can include spatially steered first signals that concurrently provide data to the wireless communication devices. The signals can include one or more second signals to the wireless communication devices to control transmission of responses from the wireless communication devices in the frequency band. The device can monitor for the responses in the frequency band. The device can control, based on a lack of reception of an expected response, a transmission of a third signal in the frequency band to prevent a transmission from another wireless communication device different than the wireless communication devices. The third signal can include information to reschedule a transmission of a response from a wireless communication device.
(FR)
La présente invention porte sur des systèmes et des techniques concernant les communications sans fil. Un exemple de système décrit comprend un dispositif configuré de façon à adresser dans une bande de fréquence des signaux aux dispositifs de communication sans fil. Les signaux peuvent comprendre des premiers signaux spatialement orientés délivrant concurremment des données aux dispositifs de communication sans fil. Les signaux peuvent comprendre un ou plusieurs deuxièmes signaux destinés aux dispositifs de communication sans fil afin de commander l'envoi de réponses par les dispositifs de communication sans fil dans la bande de fréquence. Le dispositif peut surveiller les réponses dans la bande de fréquence. Le dispositif peut commander, sur la base d'une absence de réception d'une réponse attendue, l'envoi d'un troisième signal dans la bande de fréquence afin d'empêcher un envoi en provenance d'un autre dispositif de communication sans fil distinct des dispositifs de communication sans fil. Le troisième signal peut comprendre des informations destinés à planifier à nouveau l'envoi d'une réponse par un dispositif de communication sans fil.
