    Abstract: In an example aspect, a method for submitting a PDCP PDU for transmission is provided. The method comprises submitting the PDCP PDU to a first entity for transmission over a first physical layer, and submitting the PDCP PDU to a second entity for transmission over a second physical layer. The method also comprises, after a predetermined time following submission of the PDCP PDU to the first entity and/or the second entity, instructing the first entity and the second entity to discard the PDCP PDU without transmission, or instructing the one of the first entity and the second entity to discard the PDCP PDU in response to an indication of transmission or delivery of the PDCP PDU by the other of the first entity and the second entity.

    Abstract: Various communication systems may benefit from an improved signaling protocol. For example, single-cell point-to-multipoint transmissions may benefit from improved packet retransmissions. A method includes receiving a transmission comprising one or more machine type communication packets from a network entity at a user equipment via a multicast signal. The method also includes sending feedback to the network entity during a feedback window that at least one of the one or more machine type communication packets was not properly received. In addition, the method includes receiving from the network entity a retransmission comprising at least one of the one or more machine type communication packets based on the feedback.

    Abstract: A method for communication by a scanner is described. The method includes receiving a broadcast message from a broadcasting device in a connectionless mode. The method also includes performing back channel communication with the broadcasting device on a contention basis while maintaining the connectionless mode. The scanner may send a packet to the broadcasting device while maintaining a connectionless relationship with the broadcasting device.

    Abstract: Procédé d'amélioration de la fiabilité de transmission et de la qualité de réception de flux de données vidéos sur un réseau sans fil régi par des protocoles de communication de type WIFI. Les données vidéos sont codées sous forme de paquets comportant chacun K premiers blocs de données et N blocs de redondance pour la correction au moyen d'un algorithme de correction d'erreur directe (FEC). Le flux vidéo comprend une succession desdits paquets de données émis en multicast par an moins un émetteur en direction de dispositifs de visualisation clients (5) de visualisation de type smartphones ou tablettes. Des messages d'acquittement négatif envoyés par les dispositifs clients sont utilisés par le serveur pour construire un tableau statistique à partir duquel certaines au moins des données mandantes sont renvoyées aux dispositifs clients.

    Abstract: A new air interface that is interference cancellation friendly is proposed. In one novel aspect, a novel code rate assignment with rate splitting is proposed. In one embodiment, a base station decomposes a codeword {x 1 } into two codewords {x 1a } and {x 1b }. The two codewords are applied with different code rates and/or modulation orders. More specifically, the code rate or modulation order of codeword {x 1a } is set appropriately so that a victim UE can decode and cancel {x 1a } under the channel quality of the victim UE. Typically, the channel quality of a victim UE is poorer than the channel quality of the intended UE. As a result, the MCS for {x 1a } can be lower than the MCS for {x 1b } such that the victim UE is able to apply CWIC to decode and cancel {x 1a }.

    提出了一种新的干扰消除友好型空中接口。 在一个新颖的方面,提出了一种具有速率分裂的新的码率分配。 在一个实施例中,基站将码字{x 1}分解为两个码字{x 1,y}和{x 1,...,1b}。 这两个码字以不同的码率和/或调制顺序来应用。 更具体地,码字{x1a1}的码率或调制阶数被适当地设置,使得受害者UE可以在信道质量下解码和取消{x1a} 受害者UE。 通常,受害者UE的信道质量比预期的UE的信道质量差。 结果,用于{x1aL}的MCS可以低于用于UE的MCS,使得受害者UE能够应用CWIC来解码和取消 {X <子> 1A }。
