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. | 2019-02-14 |

20190052410 | ROBUST TELEMETRY REPEATER NETWORK SYSTEM AND METHOD - A robust network telemetry repeater system exploits the repeater structure of data propagation and transmission and reception bi-directionality to increase network robustness. For example, multiple perceived receive attempts are created with no additional overhead. The system can be configured whereby nodes “hear” the transmissions of both adjacent and non-adjacent nodes forming implicit acknowledgement (“Acks”), and originating nodes can retransmit until implicit acknowledgments (“Acks”) are “heard,” indicating a successful link relay. Implicit acknowledgment can be applied to bidirectional networks, and bidirectional action can enable all nodes in the network to know the status of all other nodes. | 2019-02-14 |
20190052411 | METHOD AND APPARATUS FOR TRANSMITTING RECEIPT ACKNOWLEDGEMENT IN WIRELESS COMMUNICATION SYSTEM - One embodiment of the present invention relates to a method for a second user equipment transmitting a receipt acknowledgement in a wireless communication system, the method for transmitting the receipt acknowledgement comprising the steps of: the second UE receiving data from the first UE; determining a subframe to transmit the receipt acknowledgement by comparing a time resource pattern for transmission (T-RPT) of the first UE and a T-RPT of the second UE; and transmitting the receipt acknowledgement relating to the data from the determined subframe to the first UE. | 2019-02-14 |
