COMMUNICATION METHOD, APPARATUS AND SYSTEM FOR MULTIPLE ACCESS POINTS

摘要

Embodiments of the present invention provide a communication method, apparatus and system for multiple access points. The method includes: simultaneously sending, by a primary sending terminal and a secondary sending terminal, data corresponding to each receiving terminal to each receiving terminal through a shared channel; sending, by the primary sending terminal, BAR corresponding to the data to each receiving terminal; receiving, by the primary sending terminal, BA corresponding to the BAR and sent by each receiving terminal; and if the BA indicates that the data are correctly received by each receiving terminal, clearing the data cached in the primary sending terminal, and if the BA indicates that the data is not correctly received by each receiving terminal, retransmitting data which is not correctly received, and clearing correctly received data cached in the primary sending terminal.

主权项

1. A communication system, comprising a primary sending terminal, at least one secondary sending terminal sharing a channel with the primary sending terminal and at least one receiving terminal, wherein,
the primary sending terminal is configured to: send data corresponding to each receiving terminal to the each receiving terminal respectively; send a block acknowledgement request (BAR) corresponding to the data to the each receiving terminal respectively; receive a block acknowledgement (BA) corresponding to the BAR, which is sent by the each receiving terminal respectively; and if the BA indicates that the data is correctly received by the each receiving terminal, clear the data cached in the primary sending terminal, and if the BA indicates that the data is not correctly received by the each receiving terminal, retransmit data which is not correctly received, and clear correctly received data cached in the primary sending terminal; the secondary sending terminal is configured to: send the data to the each receiving terminal with the primary sending terminal simultaneously through a shared channel; and the receiving terminal is configured to: receive the data sent by the primary sending terminal and the secondary sending terminal; receive the BAR corresponding to the data, which is sent by the primary sending terminal; and send the BA corresponding to the BAR to the primary sending terminal.
