TRANSMITTING AND A RECEIVING DEVICE AND RESPECTIVE METHODS PERFORMED THEREBY FOR IMPROVING RETRANSMISSIONS IN WIRELESS NETWORKS

TELEFONAKTLEBOLAGET LM ER...

1. A method performed by a wireless receiving device for receiving a retransmission of a packet from a transmitting device
following a broadcast transmission of a plurality of packets from the transmitting device, wherein packets successfully decoded
during the broadcast transmission have been acknowledged by the wireless receiving device to the transmitting device and stored
in a memory associated with the wireless receiving device and unsuccessfully decoded packets have been negatively acknowledged
by the wireless receiving device to the transmitting device, the method comprising:
receiving the retransmission of the packet from the transmitting device;
sending, to the transmitting device, an acknowledge, ACK, message with respect to the received retransmitted packet;
decoding the received retransmitted packet using the stored previously successfully decoded packets;
based on a determination that the received retransmitted packet was successfully decoded, decoding stored previously partially
decoded retransmitted packets if any using the successfully decoded packet, and storing the successfully decoded packet; and,

based on a determination that the received retransmitted packet was only partially successfully decoded, storing the partially
decoded retransmitted packet.

SYSTEMS AND METHODS FOR SELF-DEFERRAL WITH DOWNLINK AND UPLINK TRANSMISSION OPPORTUNITY SHARING

Telefonaktlebolaget LM Er...

1. A method by a network node for self-deferring transmissions in a multi-carrier network, the method comprising:determining, by a first controller seeking to initiate a carrier sensing procedure in a first cell operating on a first carrier, that a second cell associated with a second controller has initiated a first transmission opportunity after a successful carrier sensing procedure, the first transmission opportunity on a second carrier that is adjacent to the first carrier;
determining, by the first controller associated with the first cell, a first transmission opportunity duration associated with the first transmission opportunity initiated in the second cell;
deferring, by the first controller, the carrier sensing procedure to be performed in the first cell, the carrier sensing procedure deferred by the first transmission opportunity duration associated with the first transmission opportunity initiated in the second cell; and
initiating the carrier sensing procedure in the first cell after the first transmission opportunity duration unless instructed by the second controller.
